4c586062b2 Fix the Debian packaging script on systems with no codename
When calling `make deb-pkg` on a system with no codename (for example
Arch Linux), lsb_release sometimes outputs `n/a` as the codename.

This breaks dpkg-parsechangelog, which can't process the changelog
correctly.

ca617dc68b builddeb: fix file permissions before packaging
Builddep is not very explicit about file permissions. Actually the file
permissions in the package are largely influenced by the umask of the
user cloning the git and building the package. If that umask does not
set go+r the resulting linux-headers package will prevent non-root users
from building out-of-tree modules. And that is probably just one
unexpected effect.
Being a packaging/install tool builddep should make sure the file
permissions are set correctly and not just derived from a value that is
never checked.

This patch sets ugo read permissions for all packaged files and derives
the executable bit for directories and executables from the file-owner.

On May 4th, Bjørn Mork provided patch 697bbc7b83 ("builddeb: include
objtool binary in headers package"). However, that one only works if
$srctree=$objtree, because the objtool binaries are not written to the

6b90bd4ba4 GCC plugin infrastructure
This patch allows to build the whole kernel with GCC plugins. It was ported from
grsecurity/PaX. The infrastructure supports building out-of-tree modules and
building in a separate directory. Cross-compilation is supported too.
Currently the x86, arm, arm64 and uml architectures enable plugins.

The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory
there. The plugins compile with these options:
 * -fno-rtti: gcc is compiled with this option so the plugins must use it too
 * -fno-exceptions: this is inherited from gcc too
 * -fasynchronous-unwind-tables: this is inherited from gcc too
 * -ggdb: it is useful for debugging a plugin (better backtrace on internal
    errors)
 * -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h)
 * -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version
    variable, plugin-version.h)

The infrastructure introduces a new Makefile target called gcc-plugins. It
supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script
chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++).
This script also checks the availability of the included headers in
scripts/gcc-plugins/gcc-common.h.

The gcc-common.h header contains frequently included headers for GCC plugins
and it has a compatibility layer for the supported gcc versions.

The gcc-generate-*-pass.h headers automatically generate the registration
structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes.

Note that 'make clean' keeps the *.so files (only the distclean or mrproper
targets clean all) because they are needed for out-of-tree modules.

Based on work created by the PaX Team.

27c3bffd23 kbuild/mkspec: support 'update-bootloader'-based systems
When uninstalling kernel RPM, we're unconditionally calling
"new-kernel-pkg --remove". This is useless on systems which are based on
'update-bootloader' script instead.

Support update-bootloader removal method as well in case the script is
present; contrary to new-kernel-pkg, this needs to be done in %postun,
otherwise update-bootloader will refuse to remove entry for kernel for
which the binary still exists.

c8b08ca558 kbuild/mkspec: fix grub2 installkernel issue
mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

4b63f60313 package Makefile: fix perf-tar targets when outdir is set
building with $srctree != $objtree, perf-tar-* targets fail
to read the MANIFEST file and add the PERF-VERSION-FILE needed
by out-of-tree builds. The build errors and an incorrect tar is created:

$ make O=build-x86 perf-targz-src-pkg
  TAR
cat: ../tools/perf/MANIFEST: No such file or directory
tar: perf-4.1.0-rc8/PERF-VERSION-FILE: Cannot stat: No such file or
dir..
tar: Exiting with failure status due to previous errors

Kbuild sets objtree to "." and srctree to ".." The command to output
MANIFEST becomes:

   $(cd ..; echo $(cat ../tools/perf/MANIFEST))

Without MANIFEST, the entire kernel source tree is added to the perf
source tarball. The *correct* fix is to keep the cd and remove srctree
from cat command line since MANIFEST has wildcards that fail to expand
working directory isn't srctree.

Second, PERF-VERSION-FILE gets not added, because in-tree build path is
hardcoded to Makefile:

   util/PERF-VERSION-GEN ../../$(perf-tar)/ 2>/dev/null)

The PERF-VERSION-GEN needs to be run from tools/perf directory,
and the output directory needs to be changed from relative to
to absolute. This can be achieved using the $(CURDIR) variable.

Also remove the error redirect to /dev/null which hid the error.

63a478fbc0 deb-pkg: Add automatic support for armhf architecture
The Debian armhf architecture uses the ARM EABI hard-float variant,
whereas armel uses the soft-float variant.  Although the kernel
doesn't use FP itself, CONFIG_VFP must be enabled to support
hard-float userland and will probably be disabled when supporting a
soft-float userland.  So set the architecture to armhf by default when
CONFIG_AEABI and CONFIG_VFP are both enabled.

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.

3716001bcb deb-pkg: add source package
Make deb-pkg build both source and binary package like make rpm-pkg does.
For people who only need binary kernel package, there is now bindeb-pkg
target, same target also used to build the .deb files if built from the
source package using dpkg-buildpackage.

Generated source package will build the same kernel .config than what
was available for make deb-pkg. The name of the source package can
be set with KDEB_SOURCENAME enviroment variable.

The source package is useful for GPL compliance, or for feeding to a
automated debian package builder.

bea107b1f1 fallback to hostname in scripts/package/builddeb

../scripts/package/Makefile:90: recipe for target 'deb-pkg' failed

In scripts/package/builddeb it tries to construct an email address (that
can be queried in /proc/version later on) but with no network,
the "hostname -f" fails. The following patch falls back to just use the
shortname if we cannot determine our FQDN.

21a59991ce scripts/package/Makefile: rpmbuild is needed for rpm targets
Before rpm release 4.1, in 2002, either the rpm command or the
rpmbuild command could be used in the rpm-pkg or binrpm-pkg targets,
and the Makefile chose the rpm command if the rpmbuild command wasn't
found.

After release 4.1, however, the rpm command could no longer be used in
place of the rpmbuild command.  As the rpmbuild command is not
installed by default, this can lead to failures with the rpm-pkg and
binrpm-pkg targets:

rpm --define "_builddir ." --target \
    x86_64 -bb ./binkernel.spec
    rpm --target: unknown option
    scripts/package/Makefile:60: recipe for target 'binrpm-pkg' failed

Change the Makefile to use rpmbuild unconditionally to avoid this.

64178cb62c builddeb: fix stripped module signatures if CONFIG_DEBUG_INFO and CONFIG_MODULE_SIG_ALL are set
If CONFIG_MODULE_SIG_ALL is set, then user expects that all modules are
automatically signed in the result package, as it's for rpm-pkg, binrpm-pkg,
tar, tar-*. For deb-pkg this is correct only if CONFIG_DEBUG_INFO
is NOT set. In that case deb-package contains signed modules.

But if CONFIG_DEBUG_INFO is set, builddeb creates separate package with
debug information. To do that, debug information from all modules
is copied into separate files by objcopy. And loadable kernel modules are
stripped afterwards. Stripping removes previously (during modules_install)
added signatures from loadable kernel modules. Therefore final deb-package
contains unsigned modules despite of set option CONFIG_MODULE_SIG_ALL.

This patch resigns all stripped modules if CONFIG_MODULE_SIG_ALL is set
to solve this problem.

d9f711db83 builddeb: Try to determine distribution
lsb_release command is a good choice to determine the distribution
name for the changelog file in the generated Debian packages [1].
Its installation is no precondition.
In Debian it is still not essential or build-essential.

Ben gave some helpful informations and detailed explanations in [2].
There he also suggested to have an option to explicitly set the
distribution name (see $KDEB_CHANGELOG_DIST variable).

Embedded the improvement as suggested by Thorsten (see [3]):

"This is suboptimal: if KDEB_CHANGELOG_DIST is defined,
lsb_release is not necessary. The following snippet
also omits using its output if it fails but still
produces any:"

Dealing with this issue I learned about "The Colon in the Shell." and
possible pitfalls in this area (see [4,5]). Furthermore, refreshed my
knowledge about redirecting outputs with the echo command (see [5]).
Special thanks to Thorsten, I enjoyed the IRC session with you.

Cooked together the snippets of Ben and Thorsten (see [2,3]).
Tested against Linux v3.19-rc2.

Thanks goes to Alexander, Ben, maximilian and Thorsten for the very
vital help.

4204111c02 deb-pkg: remove obsolete -isp option to dpkg-gencontrol
The -isp option has been deprecated, after it became the default
behaviour back in 2006.

Since dpkg 1.17.11, dpkg-gencontrol emits a warning on -isp usage.

22739edfc5 deb-pkg: Add support for powerpc little endian
The Debian powerpc little endian architecture is called ppc64el.  This
is the default architecture used by Ubuntu for powerpc.

The below checks the kernel config to see if we are compiling little
endian and sets the Debian arch appropriately.

2d08713969 builddeb: put the dbg files into the correct directory
Since the conversion of objtree to use relative pathnames (commit
7e1c04779e, "kbuild: Use relative path for $(objtree)"), the debug
info files have been ending up in /debian/dbgtmp/ in the regular
linux-image package instead of the debug files package. Fix up the
paths so that the debug files end up in the -dbg package.

This is based on a similar patch by Darrick.

c7eb3a7a17 kbuild: Fix tar-pkg with relative $(objtree)
Commit 7e1c0477 (kbuild: Use relative path for $(objtree)) assumes that
the build process does not change its working directory. make tar-pkg
was a couterexample, fix this by changing directory only for the tar
command and not for the whole script, which at one point references the
now relative $(objtree).

a1323fd163 deb-pkg: Add automatic support for s390x architecture
The Debian s390x architecture has 64-bit userland whereas s390 has
32-bit userland.  A 64-bit kernel can be used with either.  Now that
Debian supports multiarch and officially supports s390x, it makes more
sense to assign a 64-bit kernel package to s390x.

Architecture: any and use control file variables to fill in the
description.

a614d01bdd perf tools: Fix version when building out of tree
When building perf out of tree:

  $ make perf-tar-src-pkg
  $ tar -xf perf-<ver>.tar -C /tmp
  $ cd /tmp/perf<ver>
  $ make -C tools/perf

you get this warning message:
    make[1]: *** No rule to make target `kernelversion'.  Stop.

Fix it by saving the perf version in the tar file and using that for the
out of tree builds.

v2: removed short form request and fixed up version string from usual output.

7848ea7902 kbuild: Add MIPS specific files to generated package.
A lot of 64-bit systems supported by Linux/MIPS have boot firmware or
bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32
target exists to support these systems.  Therefore, it'd be nice if the tar-pkg
target recognised this, and included the right version when packaging up a
binary of the kernel.

This updates buildtar to support MIPS targets.  MIPS may use 'vmlinux'
or 'vmlinux.32' depending on the target system.  This uses 'vmlinux.32'
in preference to 'vmlinux' where present (although I should check which
is newer), including either file as /boot/vmlinux-${version}.
