The supplied script takes a signed module file and extracts the tailmost
signature (there could theoretically be more than one) and dumps all or
part of it or the unsigned file to stdout.
Call as:
scripts/extract-module-sig.pl -[0adnks] module-file >out
where the initial flag indicates which bit of the signed file you want dumping
to stdout:
(*) "-0". Dumps the unsigned data with the signature stripped.
(*) "-a". Dumps all of the signature data, including the magic number.
(*) "-d". Dumps the signature information block as a sequence of decimal
numbers in text form with spaces between (crypto algorithm type,
hash type, identifier type, signer's name length, key identifier
length and signature length).
(*) "-n". Dumps the signer's name contents.
(*) "-k". Dumps the key identifier contents.
(*) "-s". Dumps the cryptographic signature contents.
In the case that the signature is a PKCS#7 (or CMS) message, -n and -k will
print a warning to stderr and dump nothing to stdout, but will otherwise
complete okay; the entire PKCS#7/CMS message will be dumped by "-s"; and "-d"
will show "0 0 2 0 0 <pkcs#7-msg-len>".

The supplied script takes a vmlinux file - and if necessary a System.map
file - locates the system certificates list and extracts it to the named
file.
Call as:
./scripts/extract-sys-certs vmlinux certs
if vmlinux contains symbols and:
./scripts/extract-sys-certs -s System.map vmlinux certs
if it does not.
It prints something like the following to stdout:
Have 27 sections
No symbols in vmlinux, trying System.map
Have 80088 symbols
Have 1346 bytes of certs at VMA 0xffffffff8201c540
Certificate list in section .init.data
Certificate list at file offset 0x141c540
If vmlinux contains symbols then that is used rather than System.map - even
if one is given.

This patch is more of a personal preference, rather than a fix for a problem.
The current implementation used a combination of both 'cat' and 'sed'
to generate an unsorted list of kernel modules separated by while space.

Commit 3716001bcb ("deb-pkg: add source package") added the ability to
create a debian changelog file. This exposed that previously the
builddeb script hasn't cleared debian/files between builds.
As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty. With outdated entries in debian/files, builddeb
script will exit with failure. This regression impacts those who use
"make deb-pkg" target to build kernel into a .deb package and never use
"make mrproper" or other means to clean kernel tree from generated
directories.
To fix the regression, remove debian/files before starting build and in
the generated clean rule.

This patch adds arch specific code for kernel address sanitizer
(see Documentation/kasan.txt).
1/8 of kernel addresses reserved for shadow memory. There was no
big enough hole for this, so virtual addresses for shadow were
stolen from vmalloc area.
At early boot stage the whole shadow region populated with just
one physical page (kasan_zero_page). Later, this page reused
as readonly zero shadow for some memory that KASan currently
don't track (vmalloc).
After mapping the physical memory, pages for shadow memory are
allocated and mapped.
Functions like memset/memmove/memcpy do a lot of memory accesses.
If bad pointer passed to one of these function it is important
to catch this. Compiler's instrumentation cannot do this since
these functions are written in assembly.
KASan replaces memory functions with manually instrumented variants.
Original functions declared as weak symbols so strong definitions
in mm/kasan/kasan.c could replace them. Original functions have aliases
with '__' prefix in name, so we could call non-instrumented variant
if needed.
Some files built without kasan instrumentation (e.g. mm/slub.c).
Original mem* function replaced (via #define) with prefixed variants
to disable memory access checks for such files.

Currently the encoding of documents generated by DocBook depends on
the current locale. Make the output reproducible independently of
the locale, by setting the encoding to UTF-8 (LC_CTYPE=C.UTF-8) by
preference, or ASCII (LC_CTYPE=C) as a fallback.
LC_CTYPE can normally be overridden by LC_ALL, but the top-level
Makefile unsets that.

The sign-file.c program actually uses CMS rather than PKCS#7 to sign a file
since that allows the target X.509 certificate to be specified by
subjectKeyId rather than by issuer + serialNumber.
However, older versions of the OpenSSL crypto library (such as may be found
in CentOS 5.11) don't support CMS. Assume everything prior to
OpenSSL-1.0.0 doesn't support CMS and switch to using PKCS#7 in that case.
Further, the pre-1.0.0 OpenSSL only supports PKCS#7 signing with SHA1, so
give an error from the sign-file script if the caller requests anything
other than SHA1.
The compiler gives the following error with an OpenSSL crypto library
that's too old:
HOSTCC scripts/sign-file
scripts/sign-file.c:23:25: fatal error: openssl/cms.h: No such file or directory

[ The whole "openssl isn't compatible with gpl" is really just

nobody cares. - Linus ]

The "highlight" code is very sensible to the order of the hash keys,
but the order of the keys cannot be predicted. It generates
faulty DocBook entries like:
- @<function>device_for_each_child</function>
Sorting the result is not enough some times (as it's deterministic but
we can't control it).
We should use an array for that job, so we can guarantee that the order
of the regex execution on dohighlight is correct.
[jc: I think this is kind of papering around the real problem, that people
are saying @function() when "function" is not a parameter. But this makes
things better than they were before, so...]

Currently kernel-doc generates a dummy DocBook file when asked to
convert a C source file with no structured comments. For an
out-of-tree build (objtree != srctree), the title of the output file
is the absolute path name of the C source file, which later results
in a manual page being created alongside the C source file.
Change the title to be a relative path.

Docproc processes the EXPORT_SYMBOL(f1) macro and uses -nofunc f1 to
avoid duplicated documentation in the next call.
It works for most of the cases, but there are some specific situations
where a struct has the same name of an already-exported function.
Current kernel-doc behavior ignores those structs and does not add them
to the final documentation. This patch fixes it.
This is unusual, the only case I've found is the drm_modeset_lock
(function and struct) defined in drm_modeset_lock.h and
drm_modeset_lock.c. Considering this, it should only affect the DRM
documentation by including struct drm_modeset_lock to the final Docbook.

"CONST <comparison> variable" checks like:
if (NULL != foo)
and
while (0 < bar(...))
where a constant (or what appears to be a constant like an upper case
identifier) is on the left of a comparison are generally preferred to be
written using the constant on the right side like:
if (foo != NULL)
and
while (bar(...) > 0)
Add a test for this.
Add a --fix option too, but only do it when the code is immediately
surrounded by parentheses to avoid misfixing things like "(0 < bar() +
constant)"
