kbuild: rpm-pkg: fix build error when _arch is undefined

2022-07-27T12:18:00+00:00

Cross-building (bin)rpm-pkg fails on several architectures.

For example, 'make ARCH=arm binrpm-pkg' fails like follows:

  sh ./scripts/package/mkspec prebuilt > ./binkernel.spec
  rpmbuild  --define "_builddir ." --target \
          arm -bb ./binkernel.spec
  Building target platforms: arm
  Building for target arm

  make[2]: *** [Makefile:1768: modules_install] Error 2
  error: Bad exit status from /var/tmp/rpm-tmp.0S8t2F (%install)

By default, 'buildroot' contains %{_arch} (see /usr/lib/rpm/macros).

_arch is generally defined in /usr/lib/rpm/platforms/*/macros, where
the platform sub-directory is specified by --target= option for cross
builds.

If the given arch does not exist, %{_arch} is not expanded.
In the example above, --target=arm is passed to rpmbuild, but
/usr/lib/rpm/platforms/arm-linux/ does not exist.

The '%' character in the path confuses GNU make and rpmbuild.

The same occurs for such architectures as csky, microblaze, nios2, etc.

Define _arch if it has not been defined.

objtool: Add CONFIG_OBJTOOL

2022-04-22T10:32:03+00:00

Now that stack validation is an optional feature of objtool, add
CONFIG_OBJTOOL and replace most usages of CONFIG_STACK_VALIDATION with
it.

CONFIG_STACK_VALIDATION can now be considered to be frame-pointer
specific.  CONFIG_UNWINDER_ORC is already inherently valid for live
patching, so no need to "validate" it.

builddeb: Fix rootless build in setuid/setgid directory

2020-11-02T02:31:00+00:00

Building 5.10-rc1 in a setgid directory failed with the following
error:

dpkg-deb: error: control directory has bad permissions 2755 (must be
>=0755 and <=0775)

When building with fakeroot, the earlier chown call would have removed
the setgid bits, but in a rootless build they remain.

kbuild: deb-pkg: clean up package name variables

The kernel package is different for ARCH=um. Change the code

kbuild: deb-pkg: do not build linux-headers package if CONFIG_MODULES=n

2020-10-14T03:49:34+00:00

Since commit 269a535ca931 ("modpost: generate vmlinux.symvers and
reuse it for the second modpost"), with CONFIG_MODULES disabled,
"make deb-pkg" (or "make bindeb-pkg") fails with:

  find: ‘Module.symvers’: No such file or directory

If CONFIG_MODULES is disabled, it doesn't really make sense to build
the linux-headers package.

builddeb: Add support for all required debian/rules targets

2020-10-09T15:41:35+00:00

These have been required by the Debian policy for a while, even though
the tooling can detect and workaround their omission, but are a hard
requirement when using rootless builds.

[masahiro:
The following Debian policy is particularly important for rootless builds:
"Both binary-* targets should depend on the build target, or on the
 appropriate build-arch or build-indep target, so that the package is
 built if it has not been already."

This makes it possible to build the Debian packages without requiring
(pseudo-)root privileges, when the build drivers support this mode
of operation.

We should not be encoding the timestamp, otherwise we end up generating
