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

2020-10-29T09:08:07Z

[ Upstream commit bac977cbc0d6731fb8e67c2be0e4acbd959e10b3 ] 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. Fixes: 269a535ca931 ("modpost: generate vmlinux.symvers and reuse it for the second modpost") Reported-by: Josh Triplett Signed-off-by: Masahiro Yamada Signed-off-by: Sasha Levin

kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables

2020-06-11T11:14:41Z

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.

kbuild: add variables for compression tools

2020-06-06T14:42:01Z

Allow user to use alternative implementations of compression tools, such as pigz, pbzip2, pxz. For example, multi-threaded tools to speed up the build: $ make GZIP=pigz BZIP2=pbzip2 Variables _GZIP, _BZIP2, _LZOP are used internally because original env vars are reserved by the tools. The use of GZIP in gzip tool is obsolete since 2015. However, alternative implementations (e.g., pigz) still rely on it. BZIP2, BZIP, LZOP vars are not obsolescent. The credit goes to @grsecurity. As a sidenote, for multi-threaded lzma, xz compression one can use: $ export XZ_OPT="--threads=0" Signed-off-by: Denis Efremov Signed-off-by: Masahiro Yamada

kbuild: deb-pkg: fix warning when CONFIG_DEBUG_INFO is unset

2020-03-30T00:23:00Z

Creating a Debian package without CONFIG_DEBUG_INFO produces a warning that no debug package was created. This patch excludes the debug package from the control file, if no debug package is created by this configuration. Signed-off-by: Reinhard Karcher Signed-off-by: Masahiro Yamada

builddeb: split libc headers deployment out into a function

builddeb: remove redundant make for ARCH=um

2020-01-28T16:51:30Z

The kernel build has already been done before builddeb is invoked. Signed-off-by: Masahiro Yamada

builddeb: avoid invoking sub-shells where possible

2020-01-28T16:51:30Z

The commands surrounded by ( ... ) is run in a sub-shell, but you do not have to spawn a sub-shell for every single line. Use just one ( ... ) for creating debian/hdrsrcfiles. For tar, use -C option instead. Signed-off-by: Masahiro Yamada

builddeb: remove redundant $objtree/

2020-01-28T16:51:30Z

This script works only when it is invoked in the $objtree, that is, it is already relying on $objtree is '.' Signed-off-by: Masahiro Yamada

builddeb: match temporary directory name to the package name

2020-01-28T16:51:30Z

The temporary directory names, debian/hdrtmp (linux-headers package) vs debian/headertmp (linux-libc-dev package), are confusing. Matching the directory name to the package name is clearer, IMHO. Signed-off-by: Masahiro Yamada
