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

2020-10-14T03:49:39+00:00

Hard-code the names of linux-headers and debug packages in the
control file.

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

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."

builddeb: Enable rootless builds

2020-10-09T14:59:16+00:00

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

kbuild: preprocess module linker script

2020-09-24T15:36:41+00:00

There was a request to preprocess the module linker script like we
do for the vmlinux one. (https://lkml.org/lkml/2020/8/21/512)

The difference between vmlinux.lds and module.lds is that the latter
is needed for external module builds, thus must be cleaned up by
'make mrproper' instead of 'make clean'. Also, it must be created
by 'make modules_prepare'.

You cannot put it in arch/$(SRCARCH)/kernel/, which is cleaned up by
'make clean'. I moved arch/$(SRCARCH)/kernel/module.lds to
arch/$(SRCARCH)/include/asm/module.lds.h, which is included from
scripts/module.lds.S.

scripts/module.lds is fine because 'make clean' keeps all the
build artifacts under scripts/.

You can add arch-specific sections in .
