Merge tag 'docs-4.16' of git://git.lwn.net/linux 

Pull documentation updates from Jonathan Corbet:
 "Documentation updates for 4.16.

  New stuff includes refcount_t documentation, errseq documentation,
  kernel-doc support for nested structure definitions, the removal of
  lots of crufty kernel-doc support for unused formats, SPDX tag
  documentation, the beginnings of a manual for subsystem maintainers,
  and lots of fixes and updates.

  As usual, some of the changesets reach outside of Documentation/ to
  effect kerneldoc comment fixes. It also adds the new LICENSES
  directory, of which Thomas promises I do not need to be the
  maintainer"

refcount_t API compared to atomic_t
===================================
.. contents:: :local:
Introduction
============
The goal of refcount_t API is to provide a minimal API for implementing
an object's reference counters. While a generic architecture-independent
implementation from lib/refcount.c uses atomic operations underneath,
there are a number of differences between some of the ``refcount_*()`` and
``atomic_*()`` functions with regards to the memory ordering guarantees.
This document outlines the differences and provides respective examples
in order to help maintainers validate their code against the change in
these memory ordering guarantees.
The terms used through this document try to follow the formal LKMM defined in
github.com/aparri/memory-model/blob/master/Documentation/explanation.txt
memory-barriers.txt and atomic_t.txt provide more background to the
memory ordering in general and for atomic operations specifically.
Relevant types of memory ordering
=================================
.. note:: The following section only covers some of the memory
ordering types that are relevant for the atomics and reference
counters and used through this document. For a much broader picture
please consult memory-barriers.txt document.
In the absence of any memory ordering guarantees (i.e. fully unordered)
atomics & refcounters only provide atomicity and
program order (po) relation (on the same CPU). It guarantees that
each ``atomic_*()`` and ``refcount_*()`` operation is atomic and instructions
are executed in program order on a single CPU.
This is implemented using :c:func:`READ_ONCE`/:c:func:`WRITE_ONCE` and
compare-and-swap primitives.
A strong (full) memory ordering guarantees that all prior loads and
stores (all po-earlier instructions) on the same CPU are completed
before any po-later instruction is executed on the same CPU.
It also guarantees that all po-earlier stores on the same CPU
and all propagated stores from other CPUs must propagate to all
other CPUs before any po-later instruction is executed on the original
CPU (A-cumulative property). This is implemented using :c:func:`smp_mb`.
A RELEASE memory ordering guarantees that all prior loads and
stores (all po-earlier instructions) on the same CPU are completed
before the operation. It also guarantees that all po-earlier
stores on the same CPU and all propagated stores from other CPUs
must propagate to all other CPUs before the release operation
(A-cumulative property). This is implemented using
:c:func:`smp_store_release`.
A control dependency (on success) for refcounters guarantees that
if a reference for an object was successfully obtained (reference
counter increment or addition happened, function returned true),
then further stores are ordered against this operation.
Control dependency on stores are not implemented using any explicit
barriers, but rely on CPU not to speculate on stores. This is only
a single CPU relation and provides no guarantees for other CPUs.

Parameters and member arguments
-------------------------------
The kernel-doc function comments describe each parameter to the function and
function typedefs or each member of struct/union, in order, with the
``@argument:`` descriptions. For each non-private member argument, one
``@argument`` definition is needed.
The ``@argument:`` descriptions begin on the very next line following
the opening brief function description line, with no intervening blank
comment lines.
The ``@argument:`` descriptions may span multiple lines.
.. note::
If the ``@argument`` description has multiple lines, the continuation
of the description should be starting exactly at the same column as
the previous line, e. g.::
* @argument: some long description
* that continues on next lines
or::
* @argument:
* some long description
* that continues on next lines
If a function or typedef parameter argument is ``...`` (e. g. a variable
number of arguments), its description should be listed in kernel-doc
notation as::
* @...: description
Private members
~~~~~~~~~~~~~~~
Inside a struct or union description, you can use the ``private:`` and
``public:`` comment tags. Structure fields that are inside a ``private:``
area are not listed in the generated output documentation.
The ``private:`` and ``public:`` tags must begin immediately following a
``/*`` comment marker. They may optionally include comments between the
``:`` and the ending ``*/`` marker.
Example::
/**
* struct my_struct - short description
* @a: first member
* @b: second member
* @d: fourth member
*
* Longer description
*/
struct my_struct {
int a;
int b;
/* private: internal use only */
int c;
/* public: the next one is public */
int d;
};
Function documentation
----------------------
The general format of a function and function-like macro kernel-doc comment is::
/**
* function_name() - Brief description of function.
* @arg1: Describe the first argument.
* @arg2: Describe the second argument.
* One can provide multiple line descriptions
* for arguments.
*
* A longer description, with more discussion of the function function_name()
* that might be useful to those using or modifying it. Begins with an
* empty comment line, and may include additional embedded empty
* comment lines.
*
* The longer description may have multiple paragraphs.
*
* Return: Describe the return value of foobar.
*
* The return value description can also have multiple paragraphs, and should
* be placed at the end of the comment block.
*/
The brief description following the function name may span multiple lines, and
ends with an argument description, a blank comment line, or the end of the
comment block.
Return values
~~~~~~~~~~~~~
The return value, if any, should be described in a dedicated section
named ``Return``.
.. note::
#) The multi-line descriptive text you provide does *not* recognize
line breaks, so if you try to format some text nicely, as in::
* Return:
* 0 - OK
* -EINVAL - invalid argument
* -ENOMEM - out of memory
this will all run together and produce::
Return: 0 - OK -EINVAL - invalid argument -ENOMEM - out of memory
So, in order to produce the desired line breaks, you need to use a
ReST list, e. g.::
* Return:
* * 0 - OK to runtime suspend the device
* * -EBUSY - Device should not be runtime suspended
#) If the descriptive text you provide has lines that begin with
some phrase followed by a colon, each of those phrases will be taken
as a new section heading, with probably won't produce the desired
effect.
Structure, union, and enumeration documentation

The general format of a struct, union, and enum kernel-doc comment is::
/**
* struct struct_name - Brief description.
* @argument: Description of member member_name.
*
* Description of the structure.
*/
On the above, ``struct`` is used to mean structs. You can also use ``union``
and ``enum`` to describe unions and enums. ``argument`` is used
to mean struct and union member names as well as enumerations in an enum.
The brief description following the structure name may span multiple lines, and
ends with a member description, a blank comment line, or the end of the
comment block.
The kernel-doc data structure comments describe each member of the structure,
in order, with the member descriptions.
Nested structs/unions
~~~~~~~~~~~~~~~~~~~~~
It is possible to document nested structs unions, like::
/**
* struct nested_foobar - a struct with nested unions and structs
* @arg1: - first argument of anonymous union/anonymous struct
* @arg2: - second argument of anonymous union/anonymous struct
* @arg3: - third argument of anonymous union/anonymous struct
* @arg4: - fourth argument of anonymous union/anonymous struct
* @bar.st1.arg1 - first argument of struct st1 on union bar
* @bar.st1.arg2 - second argument of struct st1 on union bar
* @bar.st2.arg1 - first argument of struct st2 on union bar
* @bar.st2.arg2 - second argument of struct st2 on union bar
struct nested_foobar {
/* Anonymous union/struct*/
union {
struct {
int arg1;
int arg2;
}
struct {
void *arg3;
int arg4;
}
}
union {
struct {
int arg1;
int arg2;
} st1;
struct {
void *arg1;
int arg2;
} st2;
} bar;
};
.. note::
#) When documenting nested structs or unions, if the struct/union ``foo``
is named, the argument ``bar`` inside it should be documented as
``@foo.bar:``
#) When the nested struct/union is anonymous, the argument ``bar`` on it
should be documented as ``@bar:``

The DbC support has been added to the xHCI driver. You can get a
debug device provided by the DbC at runtime.
In order to use this, you need to make sure your kernel has been
configured to support USB_XHCI_DBGCAP. A sysfs attribute under
the xHCI device node is used to enable or disable DbC. By default,
DbC is disabled::
root@target:/sys/bus/pci/devices/0000:00:14.0# cat dbc
disabled
Enable DbC with the following command::
root@target:/sys/bus/pci/devices/0000:00:14.0# echo enable > dbc
You can check the DbC state at anytime::
root@target:/sys/bus/pci/devices/0000:00:14.0# cat dbc
enabled
Connect the debug target to the debug host with a USB 3.0 super-
speed A-to-A debugging cable. You can see /dev/ttyDBC0 created
on the debug target. You will see below kernel message lines::
root@target: tail -f /var/log/kern.log
[ 182.730103] xhci_hcd 0000:00:14.0: DbC connected
[ 191.169420] xhci_hcd 0000:00:14.0: DbC configured
[ 191.169597] xhci_hcd 0000:00:14.0: DbC now attached to /dev/ttyDBC0
Accordingly, the DbC state has been brought up to::
root@target:/sys/bus/pci/devices/0000:00:14.0# cat dbc
configured
On the debug host, you will see the debug device has been enumerated.
You will see below kernel message lines::
root@host: tail -f /var/log/kern.log
[ 79.454780] usb 2-2.1: new SuperSpeed USB device number 3 using xhci_hcd

[ 79.475392] usb 2-2.1: Manufacturer: Linux Foundation
[ 79.475393] usb 2-2.1: SerialNumber: 0001
The debug device works now. You can use any communication or debugging

kernel-doc nano-HOWTO
=====================
How to format kernel-doc comments
---------------------------------
In order to provide embedded, 'C' friendly, easy to maintain,
but consistent and extractable documentation of the functions and
data structures in the Linux kernel, the Linux kernel has adopted
a consistent style for documenting functions and their parameters,
and structures and their members.
The format for this documentation is called the kernel-doc format.
It is documented in this Documentation/kernel-doc-nano-HOWTO.txt file.
This style embeds the documentation within the source files, using
a few simple conventions. The scripts/kernel-doc perl script, the
Documentation/sphinx/kerneldoc.py Sphinx extension and other tools understand
these conventions, and are used to extract this embedded documentation
into various documents.
In order to provide good documentation of kernel functions and data
structures, please use the following conventions to format your
kernel-doc comments in Linux kernel source.
We definitely need kernel-doc formatted documentation for functions
that are exported to loadable modules using EXPORT_SYMBOL.
We also look to provide kernel-doc formatted documentation for
functions externally visible to other kernel files (not marked
"static").
We also recommend providing kernel-doc formatted documentation
for private (file "static") routines, for consistency of kernel
source code layout. But this is lower priority and at the
discretion of the MAINTAINER of that kernel source file.
Data structures visible in kernel include files should also be
documented using kernel-doc formatted comments.
The opening comment mark "/**" is reserved for kernel-doc comments.
Only comments so marked will be considered by the kernel-doc scripts,
and any comment so marked must be in kernel-doc format. Do not use
"/**" to be begin a comment block unless the comment block contains
kernel-doc formatted comments. The closing comment marker for
kernel-doc comments can be either "*/" or "**/", but "*/" is
preferred in the Linux kernel tree.
Kernel-doc comments should be placed just before the function
or data structure being described.
Example kernel-doc function comment:
/**
* foobar() - short function description of foobar
* @arg1: Describe the first argument to foobar.
* @arg2: Describe the second argument to foobar.
* One can provide multiple line descriptions
* for arguments.
*
* A longer description, with more discussion of the function foobar()
* that might be useful to those using or modifying it. Begins with
* empty comment line, and may include additional embedded empty
* comment lines.
*
* The longer description can have multiple paragraphs.
*
* Return: Describe the return value of foobar.
*/
The short description following the subject can span multiple lines
and ends with an @argument description, an empty line or the end of
the comment block.
The @argument descriptions must begin on the very next line following
this opening short function description line, with no intervening
empty comment lines.
If a function parameter is "..." (varargs), it should be listed in
kernel-doc notation as:
* @...: description
The return value, if any, should be described in a dedicated section
named "Return".
Example kernel-doc data structure comment.
/**
* struct blah - the basic blah structure
* @mem1: describe the first member of struct blah
* @mem2: describe the second member of struct blah,
* perhaps with more lines and words.
*
* Longer description of this structure.
*/
The kernel-doc function comments describe each parameter to the
function, in order, with the @name lines.
The kernel-doc data structure comments describe each structure member
in the data structure, with the @name lines.
The longer description formatting is "reflowed", losing your line
breaks. So presenting carefully formatted lists within these
descriptions won't work so well; derived documentation will lose
the formatting.
See the section below "How to add extractable documentation to your
source files" for more details and notes on how to format kernel-doc
comments.
Components of the kernel-doc system
-----------------------------------
Many places in the source tree have extractable documentation in the
form of block comments above functions. The components of this system
are:
- scripts/kernel-doc
This is a perl script that hunts for the block comments and can mark
them up directly into DocBook, ReST, man, text, and HTML. (No, not
texinfo.)
- scripts/docproc.c
This is a program for converting SGML template files into SGML
files. When a file is referenced it is searched for symbols
exported (EXPORT_SYMBOL), to be able to distinguish between internal
and external functions.
It invokes kernel-doc, giving it the list of functions that
are to be documented.
Additionally it is used to scan the SGML template files to locate
all the files referenced herein. This is used to generate dependency
information as used by make.
- Makefile
The targets 'xmldocs', 'latexdocs', 'pdfdocs', 'epubdocs'and 'htmldocs'
are used to build XML DocBook files, LaTeX files, PDF files,
ePub files and html files in Documentation/.
How to extract the documentation
--------------------------------
If you just want to read the ready-made books on the various
subsystems, just type 'make epubdocs', or 'make pdfdocs', or 'make htmldocs',
depending on your preference. If you would rather read a different format,
you can type 'make xmldocs' and then use DocBook tools to convert
Documentation/output/*.xml to a format of your choice (for example,
'db2html ...' if 'make htmldocs' was not defined).
If you want to see man pages instead, you can do this:
$ cd linux
$ scripts/kernel-doc -man $(find -name '*.c') | split-man.pl /tmp/man
$ scripts/kernel-doc -man $(find -name '*.h') | split-man.pl /tmp/man
Here is split-man.pl:
-->
#!/usr/bin/perl
if ($#ARGV < 0) {
die "where do I put the results?\n";
}
mkdir $ARGV[0],0777;
$state = 0;
while (<STDIN>) {
if (/^\.TH \"[^\"]*\" 9 \"([^\"]*)\"/) {
if ($state == 1) { close OUT }
$state = 1;
$fn = "$ARGV[0]/$1.9";
print STDERR "Creating $fn\n";
open OUT, ">$fn" or die "can't open $fn: $!\n";
print OUT $_;
} elsif ($state != 0) {
print OUT $_;
}
}
close OUT;
<--
If you just want to view the documentation for one function in one
file, you can do this:
$ scripts/kernel-doc -man -function fn file | nroff -man | less
or this:
$ scripts/kernel-doc -text -function fn file
How to add extractable documentation to your source files
---------------------------------------------------------
The format of the block comment is like this:
/**
* function_name(:)? (- short description)?
(* @parameterx(space)*: (description of parameter x)?)*
(* a blank line)?
* (Description:)? (Description of function)?
* (section header: (section description)? )*
(*)?*/
All "description" text can span multiple lines, although the
function_name & its short description are traditionally on a single line.
Description text may also contain blank lines (i.e., lines that contain
only a "*").
"section header:" names must be unique per function (or struct,
union, typedef, enum).
Use the section header "Return" for sections describing the return value
of a function.
Avoid putting a spurious blank line after the function name, or else the
description will be repeated!
All descriptive text is further processed, scanning for the following special
patterns, which are highlighted appropriately.
'funcname()' - function
'$ENVVAR' - environment variable
'&struct_name' - name of a structure (up to two words including 'struct')
'@parameter' - name of a parameter
'%CONST' - name of a constant.
NOTE 1: The multi-line descriptive text you provide does *not* recognize
line breaks, so if you try to format some text nicely, as in:
Return:
0 - cool
1 - invalid arg
2 - out of memory
this will all run together and produce:
Return: 0 - cool 1 - invalid arg 2 - out of memory
NOTE 2: If the descriptive text you provide has lines that begin with
some phrase followed by a colon, each of those phrases will be taken as
a new section heading, which means you should similarly try to avoid text
like:
Return:
0: cool
1: invalid arg
2: out of memory
every line of which would start a new section. Again, probably not
what you were after.
Take a look around the source tree for examples.
kernel-doc for structs, unions, enums, and typedefs
---------------------------------------------------
Beside functions you can also write documentation for structs, unions,
enums and typedefs. Instead of the function name you must write the name
of the declaration; the struct/union/enum/typedef must always precede
the name. Nesting of declarations is not supported.
Use the argument mechanism to document members or constants.
Inside a struct description, you can use the "private:" and "public:"
comment tags. Structure fields that are inside a "private:" area
are not listed in the generated output documentation. The "private:"
and "public:" tags must begin immediately following a "/*" comment
marker. They may optionally include comments between the ":" and the
ending "*/" marker.
Example:
/**
* struct my_struct - short description
* @a: first member
* @b: second member
*
* Longer description
*/
struct my_struct {
int a;
int b;
/* private: internal use only */
int c;
};
Including documentation blocks in source files
----------------------------------------------
To facilitate having source code and comments close together, you can
include kernel-doc documentation blocks that are free-form comments
instead of being kernel-doc for functions, structures, unions,
enums, or typedefs. This could be used for something like a
theory of operation for a driver or library code, for example.
This is done by using a DOC: section keyword with a section title. E.g.:
/**
* DOC: Theory of Operation
*
* The whizbang foobar is a dilly of a gizmo. It can do whatever you
* want it to do, at any time. It reads your mind. Here's how it works.
*
* foo bar splat
*
* The only drawback to this gizmo is that is can sometimes damage
* hardware, software, or its subject(s).
*/
DOC: sections are used in ReST files.

Configure Git
=============
This chapter describes maintainer level git configuration.
Tagged branches used in :ref:`Documentation/maintainer/pull-requests.rst
<pullrequests>` should be signed with the developers public GPG key. Signed
tags can be created by passing the ``-u`` flag to ``git tag``. However,
since you would *usually* use the same key for the same project, you can
set it once with
::
git config user.signingkey "keyname"
Alternatively, edit your ``.git/config`` or ``~/.gitconfig`` file by hand:
::
[user]
name = Jane Developer
email = jd@domain.org
signingkey = jd@domain.org
You may need to tell ``git`` to use ``gpg2``
::
[gpg]
program = /path/to/gpg2
You may also like to tell ``gpg`` which ``tty`` to use (add to your shell rc file)
::

Creating Pull Requests
======================
This chapter describes how maintainers can create and submit pull requests
to other maintainers. This is useful for transferring changes from one
maintainers tree to another maintainers tree.
This document was written by Tobin C. Harding (who at that time, was not an
experienced maintainer) primarily from comments made by Greg Kroah-Hartman
and Linus Torvalds on LKML. Suggestions and fixes by Jonathan Corbet and
Mauro Carvalho Chehab. Misrepresentation was unintentional but inevitable,
please direct abuse to Tobin C. Harding <me@tobin.cc>.
Original email thread::
http://lkml.kernel.org/r/20171114110500.GA21175@kroah.com
Create Branch
-------------
To start with you will need to have all the changes you wish to include in
the pull request on a separate branch. Typically you will base this branch
off of a branch in the developers tree whom you intend to send the pull
request to.
In order to create the pull request you must first tag the branch that you
have just created. It is recommended that you choose a meaningful tag name,
in a way that you and others can understand, even after some time. A good
practice is to include in the name an indicator of the sybsystem of origin
and the target kernel version.
Greg offers the following. A pull request with miscellaneous stuff for
drivers/char, to be applied at the Kernel version 4.15-rc1 could be named
as ``char-misc-4.15-rc1``. If such tag would be produced from a branch
named ``char-misc-next``, you would be using the following command::
git tag -s char-misc-4.15-rc1 char-misc-next
that will create a signed tag called ``char-misc-4.15-rc1`` based on the
last commit in the ``char-misc-next`` branch, and sign it with your gpg key
(see :ref:`Documentation/maintainer/configure_git.rst <configuregit>`).
Linus will only accept pull requests based on a signed tag. Other
maintainers may differ.
When you run the above command ``git`` will drop you into an editor and ask
you to describe the tag. In this case, you are describing a pull request,
so outline what is contained here, why it should be merged, and what, if
any, testing has been done. All of this information will end up in the tag
itself, and then in the merge commit that the maintainer makes if/when they
merge the pull request. So write it up well, as it will be in the kernel
tree for forever.
As said by Linus::
Anyway, at least to me, the important part is the *message*. I want
to understand what I'm pulling, and why I should pull it. I also
want to use that message as the message for the merge, so it should
not just make sense to me, but make sense as a historical record
too.
Note that if there is something odd about the pull request, that
should very much be in the explanation. If you're touching files
that you don't maintain, explain _why_. I will see it in the
diffstat anyway, and if you didn't mention it, I'll just be extra
suspicious. And when you send me new stuff after the merge window
(or even bug-fixes, but ones that look scary), explain not just
what they do and why they do it, but explain the _timing_. What
happened that this didn't go through the merge window..
I will take both what you write in the email pull request _and_ in
the signed tag, so depending on your workflow, you can either
describe your work in the signed tag (which will also automatically
make it into the pull request email), or you can make the signed
tag just a placeholder with nothing interesting in it, and describe
the work later when you actually send me the pull request.
And yes, I will edit the message. Partly because I tend to do just
trivial formatting (the whole indentation and quoting etc), but
partly because part of the message may make sense for me at pull
time (describing the conflicts and your personal issues for sending
it right now), but may not make sense in the context of a merge
commit message, so I will try to make it all make sense. I will
also fix any speeling mistaeks and bad grammar I notice,
particularly for non-native speakers (but also for native ones
;^). But I may miss some, or even add some.
Linus
Greg gives, as an example pull request::
Char/Misc patches for 4.15-rc1
Here is the big char/misc patch set for the 4.15-rc1 merge window.
Contained in here is the normal set of new functions added to all
of these crazy drivers, as well as the following brand new
subsystems:
- time_travel_controller: Finally a set of drivers for the
latest time travel bus architecture that provides i/o to
the CPU before it asked for it, allowing uninterrupted
processing
- relativity_shifters: due to the affect that the
time_travel_controllers have on the overall system, there
was a need for a new set of relativity shifter drivers to
accommodate the newly formed black holes that would
threaten to suck CPUs into them. This subsystem handles
this in a way to successfully neutralize the problems.
There is a Kconfig option to force these to be enabled
when needed, so problems should not occur.
All of these patches have been successfully tested in the latest
linux-next releases, and the original problems that it found have
all been resolved (apologies to anyone living near Canberra for the
lack of the Kconfig options in the earlier versions of the
linux-next tree creations.)
Signed-off-by: Your-name-here <your_email@domain>
The tag message format is just like a git commit id. One line at the top
for a "summary subject" and be sure to sign-off at the bottom.
Now that you have a local signed tag, you need to push it up to where it
can be retrieved::
git push origin char-misc-4.15-rc1
Create Pull Request
-------------------
The last thing to do is create the pull request message. ``git`` handily
will do this for you with the ``git request-pull`` command, but it needs a
bit of help determining what you want to pull, and on what to base the pull
against (to show the correct changes to be pulled and the diffstat). The
following command(s) will generate a pull request::
git request-pull master git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/ char-misc-4.15-rc1
Quoting Greg::
This is asking git to compare the difference from the
'char-misc-4.15-rc1' tag location, to the head of the 'master'
branch (which in my case points to the last location in Linus's
tree that I diverged from, usually a -rc release) and to use the
git:// protocol to pull from. If you wish to use https://, that
can be used here instead as well (but note that some people behind
firewalls will have problems with https git pulls).
If the char-misc-4.15-rc1 tag is not present in the repo that I am
asking to be pulled from, git will complain saying it is not there,
a handy way to remember to actually push it to a public location.
The output of 'git request-pull' will contain the location of the
git tree and specific tag to pull from, and the full text
description of that tag (which is why you need to provide good
information in that tag). It will also create a diffstat of the
pull request, and a shortlog of the individual commits that the
pull request will provide.
Linus responded that he tends to prefer the ``git://`` protocol. Other
maintainers may have different preferences. Also, note that if you are
creating pull requests without a signed tag then ``https://`` may be a
better choice. Please see the original thread for the full discussion.
Submit Pull Request
-------------------
A pull request is submitted in the same way as an ordinary patch. Send as
inline email to the maintainer and CC LKML and any sub-system specific
lists if required. Pull requests to Linus typically have a subject line
something like::
[GIT PULL] <subsystem> changes for v4.15-rc1

.. SPDX-License-Identifier: GPL-2.0
Linux kernel licensing rules
============================
The Linux Kernel is provided under the terms of the GNU General Public
License version 2 only (GPL-2.0), as published by the Free Software
Foundation, and provided in the COPYING file. This documentation file is
not meant to replace the COPYING file, but provides a description of how
each source file should be annotated to make the licensing it is governed
under clear and unambiguous.
The license in the COPYING file applies to the kernel source as a whole,
though individual source files can have a different license which is
required to be compatible with the GPL-2.0::
GPL-1.0+ : GNU General Public License v1.0 or later
GPL-2.0+ : GNU General Public License v2.0 or later
LGPL-2.0 : GNU Library General Public License v2 only
LGPL-2.0+ : GNU Library General Public License v2 or later
LGPL-2.1 : GNU Lesser General Public License v2.1 only
LGPL-2.1+ : GNU Lesser General Public License v2.1 or later
Aside from that, individual files can be provided under a dual license,
e.g. one of the compatible GPL variants and alternatively under a
permissive license like BSD, MIT etc.
The User-space API (UAPI) header files, which describe the interface of
user-space programs to the kernel are a special case. According to the
note in the kernel COPYING file, the syscall interface is a clear boundary,
which does not extend the GPL requirements to any software which uses it to
communicate with the kernel. Because the UAPI headers must be includable
into any source files which create an executable running on the Linux
kernel, the exception must be documented by a special license expression.
The common way of expressing the license of a source file is to add the
matching boilerplate text into the top comment of the file. Due to
formatting, typos etc. these "boilerplates" are hard to validate for
tools which are used in the context of license compliance.
An alternative to boilerplate text is the use of Software Package Data
Exchange (SPDX) license identifiers in each source file. SPDX license
identifiers are machine parsable and precise shorthands for the license
under which the content of the file is contributed. SPDX license
identifiers are managed by the SPDX Workgroup at the Linux Foundation and
have been agreed on by partners throughout the industry, tool vendors, and
legal teams. For further information see https://spdx.org/
The Linux kernel requires the precise SPDX identifier in all source files.
The valid identifiers used in the kernel are explained in the section
`License identifiers`_ and have been retrieved from the official SPDX
license list at https://spdx.org/licenses/ along with the license texts.
License identifier syntax
-------------------------
1. Placement:
The SPDX license identifier in kernel files shall be added at the first
possible line in a file which can contain a comment. For the majority
or files this is the first line, except for scripts which require the
'#!PATH_TO_INTERPRETER' in the first line. For those scripts the SPDX
identifier goes into the second line.
|
2. Style:
The SPDX license identifier is added in form of a comment. The comment
style depends on the file type::
C source: // SPDX-License-Identifier: <SPDX License Expression>
C header: /* SPDX-License-Identifier: <SPDX License Expression> */
ASM: /* SPDX-License-Identifier: <SPDX License Expression> */
scripts: # SPDX-License-Identifier: <SPDX License Expression>
.rst: .. SPDX-License-Identifier: <SPDX License Expression>
.dts{i}: // SPDX-License-Identifier: <SPDX License Expression>
If a specific tool cannot handle the standard comment style, then the
appropriate comment mechanism which the tool accepts shall be used. This
is the reason for having the "/\* \*/" style comment in C header
files. There was build breakage observed with generated .lds files where
'ld' failed to parse the C++ comment. This has been fixed by now, but
there are still older assembler tools which cannot handle C++ style
comments.
|
3. Syntax:
A <SPDX License Expression> is either an SPDX short form license
identifier found on the SPDX License List, or the combination of two
SPDX short form license identifiers separated by "WITH" when a license
exception applies. When multiple licenses apply, an expression consists
of keywords "AND", "OR" separating sub-expressions and surrounded by
"(", ")" .
License identifiers for licenses like [L]GPL with the 'or later' option
are constructed by using a "+" for indicating the 'or later' option.::
// SPDX-License-Identifier: GPL-2.0+
// SPDX-License-Identifier: LGPL-2.1+
WITH should be used when there is a modifier to a license needed.
For example, the linux kernel UAPI files use the expression::
// SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
// SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
Other examples using WITH exceptions found in the kernel are::
// SPDX-License-Identifier: GPL-2.0 WITH mif-exception
// SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
Exceptions can only be used with particular License identifiers. The
valid License identifiers are listed in the tags of the exception text
file. For details see the point `Exceptions`_ in the chapter `License
identifiers`_.
OR should be used if the file is dual licensed and only one license is
to be selected. For example, some dtsi files are available under dual
licenses::
// SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
Examples from the kernel for license expressions in dual licensed files::
// SPDX-License-Identifier: GPL-2.0 OR MIT
// SPDX-License-Identifier: GPL-2.0 OR BSD-2-Clause
// SPDX-License-Identifier: GPL-2.0 OR Apache-2.0
// SPDX-License-Identifier: GPL-2.0 OR MPL-1.1
// SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) OR MIT
// SPDX-License-Identifier: GPL-1.0+ OR BSD-3-Clause OR OpenSSL
AND should be used if the file has multiple licenses whose terms all
apply to use the file. For example, if code is inherited from another
project and permission has been given to put it in the kernel, but the
original license terms need to remain in effect::
// SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
Another other example where both sets of license terms need to be
adhered to is::
// SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+
License identifiers
-------------------
The licenses currently used, as well as the licenses for code added to the
kernel, can be broken down into:
1. _`Preferred licenses`:
Whenever possible these licenses should be used as they are known to be
fully compatible and widely used. These licenses are available from the
directory::
LICENSES/preferred/
in the kernel source tree.
The files in this directory contain the full license text and
`Metatags`_. The file names are identical to the SPDX license
identifier which shall be used for the license in source files.
Examples::
LICENSES/preferred/GPL-2.0
Contains the GPL version 2 license text and the required metatags::
LICENSES/preferred/MIT
Contains the MIT license text and the required metatags
_`Metatags`:
The following meta tags must be available in a license file:
- Valid-License-Identifier:
One or more lines which declare which License Identifiers are valid
inside the project to reference this particular license text. Usually
this is a single valid identifier, but e.g. for licenses with the 'or
later' options two identifiers are valid.
- SPDX-URL:
The URL of the SPDX page which contains additional information related
to the license.
- Usage-Guidance:
Freeform text for usage advice. The text must include correct examples
for the SPDX license identifiers as they should be put into source
files according to the `License identifier syntax`_ guidelines.
- License-Text:
All text after this tag is treated as the original license text
File format examples::
Valid-License-Identifier: GPL-2.0
Valid-License-Identifier: GPL-2.0+
SPDX-URL: https://spdx.org/licenses/GPL-2.0.html
Usage-Guide:
To use this license in source code, put one of the following SPDX
tag/value pairs into a comment according to the placement
guidelines in the licensing rules documentation.
For 'GNU General Public License (GPL) version 2 only' use:
SPDX-License-Identifier: GPL-2.0
For 'GNU General Public License (GPL) version 2 or any later version' use:

|
2. Not recommended licenses:
These licenses should only be used for existing code or for importing
code from a different project. These licenses are available from the
directory::
LICENSES/other/
in the kernel source tree.
The files in this directory contain the full license text and
`Metatags`_. The file names are identical to the SPDX license
identifier which shall be used for the license in source files.
Examples::
LICENSES/other/ISC
Contains the Internet Systems Consortium license text and the required
metatags::
LICENSES/other/ZLib
Contains the ZLIB license text and the required metatags.
Metatags:
The metatag requirements for 'other' licenses are identical to the
requirements of the `Preferred licenses`_.
File format example::
Valid-License-Identifier: ISC
SPDX-URL: https://spdx.org/licenses/ISC.html
Usage-Guide:
Usage of this license in the kernel for new code is discouraged
and it should solely be used for importing code from an already
existing project.
To use this license in source code, put the following SPDX
tag/value pair into a comment according to the placement
guidelines in the licensing rules documentation.
SPDX-License-Identifier: ISC
License-Text:
Full license text
|
3. _`Exceptions`:
Some licenses can be amended with exceptions which grant certain rights
which the original license does not. These exceptions are available
from the directory::
LICENSES/exceptions/
in the kernel source tree. The files in this directory contain the full
exception text and the required `Exception Metatags`_.
Examples::
LICENSES/exceptions/Linux-syscall-note
Contains the Linux syscall exception as documented in the COPYING
file of the Linux kernel, which is used for UAPI header files.
e.g. /\* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note \*/::
LICENSES/exceptions/GCC-exception-2.0
Contains the GCC 'linking exception' which allows to link any binary
independent of its license against the compiled version of a file marked
with this exception. This is required for creating runnable executables
from source code which is not compatible with the GPL.
_`Exception Metatags`:
The following meta tags must be available in an exception file:
- SPDX-Exception-Identifier:
One exception identifier which can be used with SPDX license
identifiers.
- SPDX-URL:
The URL of the SPDX page which contains additional information related
to the exception.
- SPDX-Licenses:
A comma separated list of SPDX license identifiers for which the
exception can be used.
- Usage-Guidance:
Freeform text for usage advice. The text must be followed by correct
examples for the SPDX license identifiers as they should be put into
source files according to the `License identifier syntax`_ guidelines.
- Exception-Text:
All text after this tag is treated as the original exception text
File format examples::
SPDX-Exception-Identifier: Linux-syscall-note
SPDX-URL: https://spdx.org/licenses/Linux-syscall-note.html
SPDX-Licenses: GPL-2.0, GPL-2.0+, GPL-1.0+, LGPL-2.0, LGPL-2.0+, LGPL-2.1, LGPL-2.1+
Usage-Guidance:
This exception is used together with one of the above SPDX-Licenses
to mark user-space API (uapi) header files so they can be included
into non GPL compliant user-space application code.
To use this exception add it with the keyword WITH to one of the
identifiers in the SPDX-Licenses tag:
SPDX-License-Identifier: <SPDX-License> WITH Linux-syscall-note
Exception-Text:
Full exception text
::
SPDX-Exception-Identifier: GCC-exception-2.0
SPDX-URL: https://spdx.org/licenses/GCC-exception-2.0.html
SPDX-Licenses: GPL-2.0, GPL-2.0+
Usage-Guidance:
The "GCC Runtime Library exception 2.0" is used together with one
of the above SPDX-Licenses for code imported from the GCC runtime
library.
To use this exception add it with the keyword WITH to one of the
identifiers in the SPDX-Licenses tag:
SPDX-License-Identifier: <SPDX-License> WITH GCC-exception-2.0
Exception-Text:
Full exception text
All SPDX license identifiers and exceptions must have a corresponding file
in the LICENSE subdirectories. This is required to allow tool
verification (e.g. checkpatch.pl) and to have the licenses ready to read
and extract right from the source, which is recommended by various FOSS
organizations, e.g. the `FSFE REUSE initiative <https://reuse.software/>`_.

Kernel addresses
----------------
Printing kernel addresses to userspace leaks sensitive information about
the kernel memory layout. Care should be exercised when using any printk
specifier that prints the raw address, currently %px, %p[ad], (and %p[sSb]
in certain circumstances [*]). Any file written to using one of these
specifiers should be readable only by privileged processes.
Kernels 4.14 and older printed the raw address using %p. As of 4.15-rc1
addresses printed with the specifier %p are hashed before printing.

GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our 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. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, 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 a 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 tell them 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.
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 Agreement 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 work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
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
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual 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 General
Public License.
d) 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.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 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
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying 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.
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.
7. 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 the 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
the license, you may choose any version ever published by the Free Software
Foundation.
8. 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
9. 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.
10. 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
Appendix: 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 humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, 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., 675 Mass Ave, Cambridge, MA 02139, 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) 19xx 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 a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

this definition, "control" means (a) the power, direct or indirect,
to cause the direction or management of such entity, whether by
contract or otherwise, or (b) ownership of more than fifty percent
(50%) of the outstanding shares or beneficial ownership of such
entity.
2. Source Code License.
2.1. The Initial Developer Grant.
The Initial Developer hereby grants You a world-wide, royalty-free,
non-exclusive license, subject to third party intellectual property
claims:
(a) under intellectual property rights (other than patent or
trademark) Licensable by Initial Developer to use, reproduce,
modify, display, perform, sublicense and distribute the Original
Code (or portions thereof) with or without Modifications, and/or
as part of a Larger Work; and
(b) under Patents Claims infringed by the making, using or
selling of Original Code, to make, have made, use, practice,
sell, and offer for sale, and/or otherwise dispose of the
Original Code (or portions thereof).
(c) the licenses granted in this Section 2.1(a) and (b) are
effective on the date Initial Developer first distributes
Original Code under the terms of this License.
(d) Notwithstanding Section 2.1(b) above, no patent license is
granted: 1) for code that You delete from the Original Code; 2)
separate from the Original Code; or 3) for infringements caused
by: i) the modification of the Original Code or ii) the
combination of the Original Code with other software or devices.
2.2. Contributor Grant.
Subject to third party intellectual property claims, each Contributor
hereby grants You a world-wide, royalty-free, non-exclusive license
(a) under intellectual property rights (other than patent or
trademark) Licensable by Contributor, to use, reproduce, modify,
display, perform, sublicense and distribute the Modifications
created by such Contributor (or portions thereof) either on an
unmodified basis, with other Modifications, as Covered Code
and/or as part of a Larger Work; and
(b) under Patent Claims infringed by the making, using, or
selling of Modifications made by that Contributor either alone
and/or in combination with its Contributor Version (or portions
of such combination), to make, use, sell, offer for sale, have
made, and/or otherwise dispose of: 1) Modifications made by that
Contributor (or portions thereof); and 2) the combination of
Modifications made by that Contributor with its Contributor
Version (or portions of such combination).
(c) the licenses granted in Sections 2.2(a) and 2.2(b) are
effective on the date Contributor first makes Commercial Use of
the Covered Code.
(d) Notwithstanding Section 2.2(b) above, no patent license is
granted: 1) for any code that Contributor has deleted from the
Contributor Version; 2) separate from the Contributor Version;
3) for infringements caused by: i) third party modifications of
Contributor Version or ii) the combination of Modifications made
by that Contributor with other software (except as part of the
Contributor Version) or other devices; or 4) under Patent Claims
infringed by Covered Code in the absence of Modifications made by
that Contributor.
3. Distribution Obligations.
3.1. Application of License.
The Modifications which You create or to which You contribute are
governed by the terms of this License, including without limitation
Section 2.2. The Source Code version of Covered Code may be
distributed only under the terms of this License or a future version
of this License released under Section 6.1, and You must include a
copy of this License with every copy of the Source Code You
distribute. You may not offer or impose any terms on any Source Code
version that alters or restricts the applicable version of this
License or the recipients' rights hereunder. However, You may include
an additional document offering the additional rights described in
Section 3.5.
3.2. Availability of Source Code.
Any Modification which You create or to which You contribute must be
made available in Source Code form under the terms of this License
either on the same media as an Executable version or via an accepted
Electronic Distribution Mechanism to anyone to whom you made an
Executable version available; and if made available via Electronic
Distribution Mechanism, must remain available for at least twelve (12)
months after the date it initially became available, or at least six
(6) months after a subsequent version of that particular Modification
has been made available to such recipients. You are responsible for
ensuring that the Source Code version remains available even if the
Electronic Distribution Mechanism is maintained by a third party.
3.3. Description of Modifications.
You must cause all Covered Code to which You contribute to contain a
file documenting the changes You made to create that Covered Code and
the date of any change. You must include a prominent statement that
the Modification is derived, directly or indirectly, from Original
Code provided by the Initial Developer and including the name of the
Initial Developer in (a) the Source Code, and (b) in any notice in an
Executable version or related documentation in which You describe the
origin or ownership of the Covered Code.
3.4. Intellectual Property Matters
(a) Third Party Claims.
If Contributor has knowledge that a license under a third party's
intellectual property rights is required to exercise the rights
granted by such Contributor under Sections 2.1 or 2.2,
Contributor must include a text file with the Source Code
distribution titled "LEGAL" which describes the claim and the
party making the claim in sufficient detail that a recipient will
know whom to contact. If Contributor obtains such knowledge after
the Modification is made available as described in Section 3.2,
Contributor shall promptly modify the LEGAL file in all copies
Contributor makes available thereafter and shall take other steps
(such as notifying appropriate mailing lists or newsgroups)
reasonably calculated to inform those who received the Covered
Code that new knowledge has been obtained.
(b) Contributor APIs.
If Contributor's Modifications include an application programming
interface and Contributor has knowledge of patent licenses which
are reasonably necessary to implement that API, Contributor must
also include this information in the LEGAL file.
(c) Representations.
Contributor represents that, except as disclosed pursuant to
Section 3.4(a) above, Contributor believes that Contributor's
Modifications are Contributor's original creation(s) and/or
Contributor has sufficient rights to grant the rights conveyed by
this License.
3.5. Required Notices.
You must duplicate the notice in Exhibit A in each file of the Source
Code. If it is not possible to put such notice in a particular Source
Code file due to its structure, then You must include such notice in a
location (such as a relevant directory) where a user would be likely
to look for such a notice. If You created one or more Modification(s)
You may add your name as a Contributor to the notice described in
Exhibit A. You must also duplicate this License in any documentation
for the Source Code where You describe recipients' rights or ownership
rights relating to Covered Code. You may choose to offer, and to
charge a fee for, warranty, support, indemnity or liability
obligations to one or more recipients of Covered Code. However, You
may do so only on Your own behalf, and not on behalf of the Initial
Developer or any Contributor. You must make it absolutely clear than
any such warranty, support, indemnity or liability obligation is
offered by You alone, and You hereby agree to indemnify the Initial
Developer and every Contributor for any liability incurred by the
Initial Developer or such Contributor as a result of warranty,
support, indemnity or liability terms You offer.
3.6. Distribution of Executable Versions.
You may distribute Covered Code in Executable form only if the
requirements of Section 3.1-3.5 have been met for that Covered Code,
and if You include a notice stating that the Source Code version of
the Covered Code is available under the terms of this License,
including a description of how and where You have fulfilled the
obligations of Section 3.2. The notice must be conspicuously included
in any notice in an Executable version, related documentation or
collateral in which You describe recipients' rights relating to the
Covered Code. You may distribute the Executable version of Covered
Code or ownership rights under a license of Your choice, which may
contain terms different from this License, provided that You are in
compliance with the terms of this License and that the license for the
Executable version does not attempt to limit or alter the recipient's
rights in the Source Code version from the rights set forth in this
License. If You distribute the Executable version under a different
license You must make it absolutely clear that any terms which differ
from this License are offered by You alone, not by the Initial
Developer or any Contributor. You hereby agree to indemnify the
Initial Developer and every Contributor for any liability incurred by
the Initial Developer or such Contributor as a result of any such
terms You offer.
3.7. Larger Works.
You may create a Larger Work by combining Covered Code with other code
not governed by the terms of this License and distribute the Larger
Work as a single product. In such a case, You must make sure the
requirements of this License are fulfilled for the Covered Code.
4. Inability to Comply Due to Statute or Regulation.
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Code due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description
must be included in the LEGAL file described in Section 3.4 and must
be included with all distributions of the Source Code. Except to the
extent prohibited by statute or regulation, such description must be
sufficiently detailed for a recipient of ordinary skill to be able to
understand it.
5. Application of this License.
This License applies to code to which the Initial Developer has
attached the notice in Exhibit A and to related Covered Code.
6. Versions of the License.
6.1. New Versions.
Netscape Communications Corporation ("Netscape") may publish revised
and/or new versions of the License from time to time. Each version
will be given a distinguishing version number.
6.2. Effect of New Versions.
Once Covered Code has been published under a particular version of the
License, You may always continue to use it under the terms of that
version. You may also choose to use such Covered Code under the terms
of any subsequent version of the License published by Netscape. No one
other than Netscape has the right to modify the terms applicable to
Covered Code created under this License.
6.3. Derivative Works.
If You create or use a modified version of this License (which you may
only do in order to apply it to code which is not already Covered Code
governed by this License), You must (a) rename Your license so that
the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
"MPL", "NPL" or any confusingly similar phrase do not appear in your
license (except to note that your license differs from this License)
and (b) otherwise make it clear that Your version of the license
contains terms which differ from the Mozilla Public License and
Netscape Public License. (Filling in the name of the Initial
Developer, Original Code or Contributor in the notice described in
Exhibit A shall not of themselves be deemed to be modifications of
this License.)
7. DISCLAIMER OF WARRANTY.
COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
8. TERMINATION.
8.1. This License and the rights granted hereunder will terminate
automatically if You fail to comply with terms herein and fail to cure
such breach within 30 days of becoming aware of the breach. All
sublicenses to the Covered Code which are properly granted shall
survive any termination of this License. Provisions which, by their
nature, must remain in effect beyond the termination of this License
shall survive.
8.2. If You initiate litigation by asserting a patent infringement
claim (excluding declatory judgment actions) against Initial Developer
or a Contributor (the Initial Developer or Contributor against whom
You file such action is referred to as "Participant") alleging that:
(a) such Participant's Contributor Version directly or indirectly
infringes any patent, then any and all rights granted by such
Participant to You under Sections 2.1 and/or 2.2 of this License
shall, upon 60 days notice from Participant terminate prospectively,
unless if within 60 days after receipt of notice You either: (i)
agree in writing to pay Participant a mutually agreeable reasonable
royalty for Your past and future use of Modifications made by such
Participant, or (ii) withdraw Your litigation claim with respect to
the Contributor Version against such Participant. If within 60 days
of notice, a reasonable royalty and payment arrangement are not
mutually agreed upon in writing by the parties or the litigation claim
is not withdrawn, the rights granted by Participant to You under
Sections 2.1 and/or 2.2 automatically terminate at the expiration of
the 60 day notice period specified above.
(b) any software, hardware, or device, other than such Participant's
Contributor Version, directly or indirectly infringes any patent, then
any rights granted to You by such Participant under Sections 2.1(b)
and 2.2(b) are revoked effective as of the date You first made, used,
sold, distributed, or had made, Modifications made by that
Participant.
8.3. If You assert a patent infringement claim against Participant
alleging that such Participant's Contributor Version directly or
indirectly infringes any patent where such claim is resolved (such as
by license or settlement) prior to the initiation of patent
infringement litigation, then the reasonable value of the licenses
granted by such Participant under Sections 2.1 or 2.2 shall be taken
into account in determining the amount or value of any payment or
license.
8.4. In the event of termination under Sections 8.1 or 8.2 above,
all end user license agreements (excluding distributors and resellers)
which have been validly granted by You or any distributor hereunder
prior to termination shall survive termination.
9. LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
(INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
10. U.S. GOVERNMENT END USERS.
The Covered Code is a "commercial item," as that term is defined in
48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
software" and "commercial computer software documentation," as such
terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
all U.S. Government End Users acquire Covered Code with only those
rights set forth herein.
11. MISCELLANEOUS.
This License represents the complete agreement concerning subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. This License shall be governed by
California law provisions (except to the extent applicable law, if
any, provides otherwise), excluding its conflict-of-law provisions.
With respect to disputes in which at least one party is a citizen of,
or an entity chartered or registered to do business in the United
States of America, any litigation relating to this License shall be
subject to the jurisdiction of the Federal Courts of the Northern
District of California, with venue lying in Santa Clara County,
California, with the losing party responsible for costs, including
without limitation, court costs and reasonable attorneys' fees and
expenses. The application of the United Nations Convention on
Contracts for the International Sale of Goods is expressly excluded.
Any law or regulation which provides that the language of a contract
shall be construed against the drafter shall not apply to this
License.
12. RESPONSIBILITY FOR CLAIMS.
As between Initial Developer and the Contributors, each party is
responsible for claims and damages arising, directly or indirectly,
out of its utilization of rights under this License and You agree to
work with Initial Developer and Contributors to distribute such
responsibility on an equitable basis. Nothing herein is intended or
shall be deemed to constitute any admission of liability.
13. MULTIPLE-LICENSED CODE.
Initial Developer may designate portions of the Covered Code as
"Multiple-Licensed". "Multiple-Licensed" means that the Initial
Developer permits you to utilize portions of the Covered Code under
Your choice of the MPL or the alternative licenses, if any, specified
by the Initial Developer in the file described in Exhibit A.

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

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

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
51 Franklin St, 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.
[This is the first released version of the library GPL. It is numbered 2
because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public Licenses are
intended to guarantee your freedom to share and change free software--to
make sure the software is free for all its users.
This license, the Library General Public License, applies to some specially
designated Free Software Foundation software, and to any other libraries
whose authors decide to use it. You can use it for your libraries, 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 library, or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You
must make sure that they, too, receive or can get the source code. If you
link a program with the library, you must provide complete object files to
the recipients so that they can relink them with the library, after making
changes to the library and recompiling it. And you must show them these
terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright the
library, and (2) offer you this license which gives you legal permission to
copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain that
everyone understands that there is no warranty for this free library. If
the library is modified by someone else and passed on, we want its
recipients to know that what they have is not the original version, 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 companies distributing free software will
individually obtain patent licenses, thus in effect transforming the
program into proprietary software. To prevent this, we have made it clear
that any patent must be licensed for everyone's free use or not licensed at
all.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General Public
License for libraries did not effectively promote software sharing, because
most developers did not use the libraries. We concluded that weaker
conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the users
of those programs of all benefit from the free status of the libraries
themselves. This Library General Public License is intended to permit
developers of non-free programs to use free libraries, while preserving
your freedom as a user of such programs to change the free libraries that
are incorporated in them. (We have not seen how to achieve this as regards
changes in header files, but we have achieved it as regards changes in the
actual functions of the Library.) The hope is that this will lead to faster
development of free libraries.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code
derived from the library, while the latter only works together with the
library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which contains a
notice placed by the copyright holder or other authorized party saying
it may be distributed under the terms of this Library General Public
License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which
has been distributed under these terms. A "work based on the Library"
means either the Library or any derivative work under copyright law:
that is to say, a work containing the Library or a portion of it, either
verbatim or with modifications and/or translated straightforwardly into
another language. (Hereinafter, translation is included without
limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making
modifications to it. For a library, 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 library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of running
a program using the Library is not restricted, and output from such a
program is covered only if its contents constitute a work based on the
Library (independent of the use of the Library in a tool for writing
it). Whether that is true depends on what the Library does and what the
program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete
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
distribute a copy of this License along with the Library.
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 Library or any portion of it,
thus forming a work based on the Library, 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) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating
that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to
all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table
of data to be supplied by an application program that uses the
facility, other than as an argument passed when the facility is
invoked, then you must make a good faith effort to ensure that, in
the event an application does not supply such function or table, the
facility still operates, and performs whatever part of its purpose
remains meaningful.
(For example, a function in a library to compute square roots has a
purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must be
optional: if the application does not supply it, the square root
function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library, 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 Library, 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 Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of a
storage or distribution medium does not bring the other work under the
scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so that
they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in these
notices.
Once this change is made in a given copy, it is irreversible for that
copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the
Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you 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.
If distribution of 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 satisfies the requirement to distribute the
source code, even though third parties are not compelled to copy the
source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with
it, is called a "work that uses the Library". Such a work, in isolation,
is not a derivative work of the Library, and therefore falls outside the
scope of this License.
However, linking a "work that uses the Library" with the Library creates
an executable that is a derivative of the Library (because it contains
portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License. Section 6
states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is
not. Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure
layouts and accessors, and small macros and small inline functions (ten
lines or less in length), then the use of the object file is
unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section
6. Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or link a
"work that uses the Library" with the Library to produce a work
containing portions of the Library, and distribute that work under terms
of your choice, provided that the terms permit modification of the work
for the customer's own use and reverse engineering for debugging such
modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work during
execution displays copyright notices, you must include the copyright
notice for the Library among them, as well as a reference directing the
user to the copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable
source code for the Library including whatever changes were used in
the work (which must be distributed under Sections 1 and 2 above);
and, if the work is an executable linked with the Library, with the
complete machine-readable "work that uses the Library", as object
code and/or source code, so that the user can modify the Library and
then relink to produce a modified executable containing the modified
Library. (It is understood that the user who changes the contents of
definitions files in the Library will not necessarily be able to
recompile the application to use the modified definitions.)
b) Accompany the work with a written offer, valid for at least three
years, to give the same user the materials specified in Subsection
6a, above, for a charge no more than the cost of performing this
distribution.
c) If distribution of the work is made by offering access to copy from a
designated place, offer equivalent access to copy the above specified
materials from the same place.
d) Verify that the user has already received a copy of these materials
or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library"
must include any data and utility programs needed for reproducing the
executable from it. 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.
It may happen that this requirement contradicts the license restrictions
of other proprietary libraries that do not normally accompany the
operating system. Such a contradiction means you cannot use both them
and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library
side-by-side in a single library together with other library facilities
not covered by this License, and distribute such a combined library,
provided that the separate distribution of the work based on the Library
and of the other library facilities is otherwise permitted, and provided
that you do these two things:
a) Accompany the combined library with a copy of the same work based on
the Library, uncombined with any other library facilities. This must
be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part
of it is a work based on the Library, and explaining where to find
the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the
Library except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense, link with, or distribute the
Library 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.
9. 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 Library or its derivative works. These actions are prohibited by law
if you do not accept this License. Therefore, by modifying or
distributing the Library (or any work based on the Library), you
indicate your acceptance of this License to do so, and all its terms and
conditions for copying, distributing or modifying the Library or works
based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
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.
11. 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 Library at all. For example, if a patent license
would not permit royalty-free redistribution of the Library 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 Library.
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.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Library 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.
13. The Free Software Foundation may publish revised and/or new versions of
the Library 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 Library
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 Library does not specify a license
version number, you may choose any version ever published by the Free
Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
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
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE LIBRARY "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 LIBRARY IS WITH
YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION.
16. 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 LIBRARY 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 LIBRARY
(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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. 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 library's name and an idea of what it does.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 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.
[This is the first released version of the Lesser GPL. It also counts as
the successor of the GNU Library Public License, version 2, hence the
version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public Licenses are
intended to guarantee your freedom to share and change free software--to
make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software
Foundation and other authors who decide to use it. You can use it too, but
we suggest you first think carefully about whether this license or the
ordinary General Public License is the better strategy to use in any
particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, 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 and use pieces of it in new free
programs; and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for you if
you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for
a fee, you must give the recipients all the rights that we gave you. You
must make sure that they, too, receive or can get the source code. If you
link other code with the library, you must provide complete object files to
the recipients, so that they can relink them with the library after making
changes to the library and recompiling it. And you must show them these
terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any
free program. We wish to make sure that a company cannot effectively
restrict the users of a free program by obtaining a restrictive license
from a patent holder. Therefore, we insist that any patent license obtained
for a version of the library must be consistent with the full freedom of
use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU
General Public License. This license, the GNU Lesser General Public
License, applies to certain designated libraries, and is quite different
from the ordinary General Public License. We use this license for certain
libraries in order to permit linking those libraries into non-free
programs.
When a program is linked with a library, whether statically or using a
shared library, the combination of the two is legally speaking a combined
work, a derivative of the original library. The ordinary General Public
License therefore permits such linking only if the entire combination fits
its criteria of freedom. The Lesser General Public License permits more lax
criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does
Less to protect the user's freedom than the ordinary General Public
License. It also provides other free software developers Less of an
advantage over competing non-free programs. These disadvantages are the
reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to encourage
the widest possible use of a certain library, so that it becomes a de-facto
standard. To achieve this, non-free programs must be allowed to use the
library. A more frequent case is that a free library does the same job as
widely used non-free libraries. In this case, there is little to gain by
limiting the free library to free software only, so we use the Lesser
General Public License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free
software. For example, permission to use the GNU C Library in non-free
programs enables many more people to use the whole GNU operating system, as
well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a
modified version of the Library.
The precise terms and conditions for copying, distribution and modification
follow. Pay close attention to the difference between a "work based on the
library" and a "work that uses the library". The former contains code
derived from the library, whereas the latter must be combined with the
library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other
authorized party saying it may be distributed under the terms of this
Lesser General Public License (also called "this License"). Each
licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which
has been distributed under these terms. A "work based on the Library"
means either the Library or any derivative work under copyright law:
that is to say, a work containing the Library or a portion of it, either
verbatim or with modifications and/or translated straightforwardly into
another language. (Hereinafter, translation is included without
limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making
modifications to it. For a library, 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 library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of running
a program using the Library is not restricted, and output from such a
program is covered only if its contents constitute a work based on the
Library (independent of the use of the Library in a tool for writing
it). Whether that is true depends on what the Library does and what the
program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete
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
distribute a copy of this License along with the Library.
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 Library or any portion of it,
thus forming a work based on the Library, 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) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating
that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to
all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table
of data to be supplied by an application program that uses the
facility, other than as an argument passed when the facility is
invoked, then you must make a good faith effort to ensure that, in
the event an application does not supply such function or table, the
facility still operates, and performs whatever part of its purpose
remains meaningful.
(For example, a function in a library to compute square roots has a
purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must be
optional: if the application does not supply it, the square root
function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library, 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 Library, 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 Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of a
storage or distribution medium does not bring the other work under the
scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so that
they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in these
notices.
Once this change is made in a given copy, it is irreversible for that
copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the
Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of
it, under Section 2) in object code or executable form under the terms
of Sections 1 and 2 above provided that you 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.
If distribution of 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 satisfies the requirement to distribute the
source code, even though third parties are not compelled to copy the
source along with the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with
it, is called a "work that uses the Library". Such a work, in isolation,
is not a derivative work of the Library, and therefore falls outside the
scope of this License.
However, linking a "work that uses the Library" with the Library creates
an executable that is a derivative of the Library (because it contains
portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License. Section 6
states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is
not. Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure
layouts and accessors, and small macros and small inline functions (ten
lines or less in length), then the use of the object file is
unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section
6. Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a
"work that uses the Library" with the Library to produce a work
containing portions of the Library, and distribute that work under terms
of your choice, provided that the terms permit modification of the work
for the customer's own use and reverse engineering for debugging such
modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work during
execution displays copyright notices, you must include the copyright
notice for the Library among them, as well as a reference directing the
user to the copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable
source code for the Library including whatever changes were used in
the work (which must be distributed under Sections 1 and 2 above);
and, if the work is an executable linked with the Library, with the
complete machine-readable "work that uses the Library", as object
code and/or source code, so that the user can modify the Library and
then relink to produce a modified executable containing the modified
Library. (It is understood that the user who changes the contents of
definitions files in the Library will not necessarily be able to
recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a copy
of the library already present on the user's computer system, rather
than copying library functions into the executable, and (2) will
operate properly with a modified version of the library, if the user
installs one, as long as the modified version is interface-compatible
with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three
years, to give the same user the materials specified in Subsection
6a, above, for a charge no more than the cost of performing this
distribution.
d) If distribution of the work is made by offering access to copy from a
designated place, offer equivalent access to copy the above specified
materials from the same place.
e) Verify that the user has already received a copy of these materials
or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library"
must include any data and utility programs needed for reproducing the
executable from it. However, as a special exception, the materials to be
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.
It may happen that this requirement contradicts the license restrictions
of other proprietary libraries that do not normally accompany the
operating system. Such a contradiction means you cannot use both them
and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library
side-by-side in a single library together with other library facilities
not covered by this License, and distribute such a combined library,
provided that the separate distribution of the work based on the Library
and of the other library facilities is otherwise permitted, and provided
that you do these two things:
a) Accompany the combined library with a copy of the same work based on
the Library, uncombined with any other library facilities. This must
be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part
of it is a work based on the Library, and explaining where to find
the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the
Library except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense, link with, or distribute the
Library 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.
9. 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 Library or its derivative works. These actions are prohibited by law
if you do not accept this License. Therefore, by modifying or
distributing the Library (or any work based on the Library), you
indicate your acceptance of this License to do so, and all its terms and
conditions for copying, distributing or modifying the Library or works
based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
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 with this License.
11. 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 Library at all. For example, if a patent license
would not permit royalty-free redistribution of the Library 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 Library.
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.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Library 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.
13. The Free Software Foundation may publish revised and/or new versions of
the Lesser 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 Library
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 Library does not specify a license
version number, you may choose any version ever published by the Free
Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
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
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE LIBRARY "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 LIBRARY IS WITH
YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
NECESSARY SERVICING, REPAIR OR CORRECTION.
16. 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 LIBRARY 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 LIBRARY
(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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. 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 library's name and an idea of what it does.
