Alexander Kapshuk cbb57d10af ver_linux: libc, input redirection to sed fails in some distros
The current implementation has been found not to work across all distros.

The proposed implementation relies on 'sed' to both output the string
'Linux C Library' as well as to open '/proc/self/maps' without having
to use output redirection.

Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2

Alexander Kapshuk 12b2732c82 ver_linux: util-linux, 'fdformat' not ubiquitous any longer
The current implementation relies on 'fdformat' to output the version of
'util-linux'. This does not seem to be reliable any longer, as 'fdformat'
does not seem to come preinstalled in all ditros these days.

The proposed implementation uses 'mount' to output both the version
of 'util-linux' and 'mount' proper, as 'mount' is also a part of the
'util-linux' package.

Riku Voipio 8d740a37b9 builddeb: remove debian/files before build
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  With outdated entries in debian/files, builddeb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.

Michael Ellerman bd960f0983 scripts/kconfig/Makefile: Fix KBUILD_DEFCONFIG check when building with O=
My recent commit d2036f30cf ("scripts/kconfig/Makefile: Allow
KBUILD_DEFCONFIG to be a target"), contained a bug in that when it
checks if KBUILD_DEFCONFIG is a file it forgets to prepend $(srctree) to
the path.

This causes the build to fail when building out of tree (with O=), and
when the value of KBUILD_DEFCONFIG is 'defconfig'. In that case we will
fail to find the 'defconfig' file, because we look in the build
directory not $(srctree), and so we will call Make again with
'defconfig' as the target. From there we loop infinitely calling 'make
defconfig' again and again.

The fix is simple, we need to look for the file under $(srctree).

Gabriel de Perthuis ed94fea5ba kconfig/merge_config.sh: Support KCONFIG_CONFIG
All make targets support $KCONFIG_CONFIG because they
run scripts/kconf.  Make sure merge_config.sh accesses the
correct file in all cases.

Previously this script broke in two different code paths,
one for targets like kvmconfig (which use merge_config.sh -m
then call a target that respects KCONFIG_CONFIG) and one for
direct use of the script without -m, which called make rules
that edit KCONFIG_CONFIG but verified a different file.

The buildsystem will now only search for Qt 4 and Qt 5. Support for Qt 2
and 3 was dropped in the previous commits (Qt 3 was EOL'ed in 2010 or
so...).

For Qt 5, to be future-proof with the future direction notice appearing
in the 5.5 release, C++11 support is automatically enabled.

Andrey Ryabinin 39d114ddc6 arm64: add KASAN support
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.

The section mismatch warning can be easy to miss during the kernel build

Setting CONFIG_SECTION_MISMATCH_WARN_ONLY=y causes these warnings to be

Michael Ellerman d2036f30cf scripts/kconfig/Makefile: Allow KBUILD_DEFCONFIG to be a target
Arch Makefiles can set KBUILD_DEFCONFIG to tell kbuild the name of the
defconfig that should be built by default.

However currently there is an assumption that KBUILD_DEFCONFIG points to
a file at arch/$(SRCARCH)/configs/$(KBUILD_DEFCONFIG).

We would like to use a target, using merge_config, as our defconfig, so
adapt the logic in scripts/kconfig/Makefile to allow that.

To minimise the chance of breaking anything, we first check if
KBUILD_DEFCONFIG is a file, and if so we do the old logic. If it's not a
file, then we call the top-level Makefile with KBUILD_DEFCONFIG as the
target.

David Howells 283e8ba2df MODSIGN: Change from CMS to PKCS#7 signing if the openssl is too old
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

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.

Danilo Cesar Lemes de Paula 23aebb3c05 scripts/kernel-doc: Processing -nofunc for functions only
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.

Linus Torvalds b793c005ce Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris:
 "Highlights:

   - PKCS#7 support added to support signed kexec, also utilized for
     module signing.  See comments in 3f1e1bea.

     ** NOTE: this requires linking against the OpenSSL library, which
        must be installed, e.g.  the openssl-devel on Fedora **

   - Smack
      - add IPv6 host labeling; ignore labels on kernel threads
      - support smack labeling mounts which use binary mount data

   - SELinux:
      - add ioctl whitelisting (see
        http://kernsec.org/files/lss2015/vanderstoep.pdf)
      - fix mprotect PROT_EXEC regression caused by mm change

   - Seccomp:
      - add ptrace options for suspend/resume"

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (57 commits)
  PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use them
  Documentation/Changes: Now need OpenSSL devel packages for module signing
  scripts: add extract-cert and sign-file to .gitignore
  modsign: Handle signing key in source tree
  modsign: Use if_changed rule for extracting cert from module signing key
  Move certificate handling to its own directory
  sign-file: Fix warning about BIO_reset() return value
  PKCS#7: Add MODULE_LICENSE() to test module
  Smack - Fix build error with bringup unconfigured

Zhao Lei 35108d7138 scripts/spelling.txt: add some typo-words
I wrote a small script to show word-pair from all linux spelling-typo
commits, and get following result by sort | uniq -c:

    181 occured -> occurred
     78 transfered -> transferred
     67 recieved -> received
     65 dependant -> dependent
     58 wether -> whether
     56 accomodate -> accommodate
     54 occured -> occurred
     51 recieve -> receive
     47 cant -> can't
     40 sucessfully -> successfully
     ...

Some of them are not in spelling.txt, this patch adds the most common
word-pairs into spelling.txt.

Robert Jarzmik e260fe01fa scripts: decode_stacktrace: fix ARM architecture decoding
Fix the stack decoder for the ARM architecture.
An ARM stack is designed as :

[   81.547704] [<c023eb04>] (bucket_find_contain) from [<c023ec88>] (check_sync+0x40/0x4f8)
[   81.559668] [<c023ec88>] (check_sync) from [<c023f8c4>] (debug_dma_sync_sg_for_cpu+0x128/0x194)
[   81.571583] [<c023f8c4>] (debug_dma_sync_sg_for_cpu) from [<c0327dec>] (__videobuf_s

The current script doesn't expect the symbols to be bound by
parenthesis, and triggers the following errors :

  awk: cmd. line:1: error: Unmatched ( or \(: / (check_sync$/
  [   81.547704] (bucket_find_contain) from (check_sync+0x40/0x4f8)

Fix it by chopping starting and ending parenthesis from the each symbol
name.

As a side note, this probably comes from the function
dump_backtrace_entry(), which is implemented differently for each
architecture.  That makes a single decoding script a bit a challenge.

Bart Van Assche d40e1e6532 kerneldoc: Convert error messages to GNU error message format
Editors like emacs and vi recognize a number of error message formats.
The format used by the kerneldoc tool is not recognized by emacs.

Change the kerneldoc error message format to the GNU style such that the
emacs prev-error and next-error commands can be used to navigate through
kerneldoc error messages.  For more information about the GNU error
message format, see also
  https://www.gnu.org/prep/standards/html_node/Errors.html.

misspelled words for check:-

I myself did these spell mistakes in changelog for patches, Thus
suggesting to add in spelling.txt, so that checkpatch.pl warns it
earlier.  References:-

./arch/powerpc/kernel/exceptions-64e.S:456: . . . make sure you chcek
