kbuild: fix argument parsing in scripts/config

2025-06-04T12:41:58+00:00

[ Upstream commit f757f6011c92b5a01db742c39149bed9e526478f ] The script previously assumed --file was always the first argument, which caused issues when it appeared later. This patch updates the parsing logic to scan all arguments to find --file, sets the config file correctly, and resets the argument list with the remaining commands. It also fixes --refresh to respect --file by passing KCONFIG_CONFIG=$FN to make oldconfig. Signed-off-by: Seyediman Seyedarab Signed-off-by: Masahiro Yamada Signed-off-by: Sasha Levin

kconfig: merge_config: use an empty file as initfile

2025-06-04T12:41:53+00:00

[ Upstream commit a26fe287eed112b4e21e854f173c8918a6a8596d ] The scripts/kconfig/merge_config.sh script requires an existing $INITFILE (or the $1 argument) as a base file for merging Kconfig fragments. However, an empty $INITFILE can serve as an initial starting point, later referenced by the KCONFIG_ALLCONFIG Makefile variable if -m is not used. This variable can point to any configuration file containing preset config symbols (the merged output) as stated in Documentation/kbuild/kconfig.rst. When -m is used $INITFILE will contain just the merge output requiring the user to run make (i.e. KCONFIG_ALLCONFIG=<$INITFILE> make or make olddefconfig). Instead of failing when `$INITFILE` is missing, create an empty file and use it as the starting point for merges.

objtool: Silence more KCOV warnings, part 2

2025-05-02T05:51:04+00:00

commit 55c78035a1a8dfb05f1472018ce2a651701adb7d upstream. Similar to GCOV, KCOV can leave behind dead code and undefined behavior. Warnings related to those should be ignored. The previous commit: 6b023c784204 ("objtool: Silence more KCOV warnings") ... only did so for CONFIG_CGOV_KERNEL. Also do it for CONFIG_KCOV, but for real this time. Fixes the following warning: vmlinux.o: warning: objtool: synaptics_report_mt_data: unexpected end of section .text.synaptics_report_mt_data Fixes: 6b023c784204 ("objtool: Silence more KCOV warnings") Reported-by: kernel test robot Signed-off-by: Josh Poimboeuf Signed-off-by: Ingo Molnar Cc: Linus Torvalds Link: https://lore.kernel.org/r/a44ba16e194bcbc52c1cef3d3cd9051a62622723.1743481539.git.jpoimboe@kernel.org Closes: https://lore.kernel.org/oe-kbuild-all/202503282236.UhfRsF3B-lkp@intel.com/ Signed-off-by: Greg Kroah-Hartman

sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3

commit 558bdc45dfb2669e1741384a0c80be9c82fa052c upstream. ENGINE API has been deprecated since OpenSSL version 3.0 [1]. Distros have started dropping support from headers and in future it will likely disappear also from library. It has been superseded by the PROVIDER API, so use it instead for OPENSSL MAJOR >= 3.

selinux: Chain up tool resolving errors in install_policy.sh

2025-04-10T12:37:26+00:00

[ Upstream commit 6ae0042f4d3f331e841495eb0a3d51598e593ec2 ] Subshell evaluations are not exempt from errexit, so if a command is not available, `which` will fail and exit the script as a whole. This causes the helpful error messages to not be printed if they are tacked on using a `$?` comparison. Resolve the issue by using chains of logical operators, which are not subject to the effects of errexit.

kbuild: Move -Wenum-enum-conversion to W=2

2025-02-17T08:40:27+00:00

commit 8f6629c004b193d23612641c3607e785819e97ab upstream. -Wenum-enum-conversion was strengthened in clang-19 to warn for C, which caused the kernel to move it to W=1 in commit 75b5ab134bb5 ("kbuild: Move -Wenum-{compare-conditional,enum-conversion} into W=1") because there were numerous instances that would break builds with -Werror. Unfortunately, this is not a full solution, as more and more developers, subsystems, and distributors are building with W=1 as well, so they continue to see the numerous instances of this warning. Since the move to W=1, there have not been many new instances that have appeared through various build reports and the ones that have appeared seem to be following similar existing patterns, suggesting that most instances of this warning will not be real issues. The only alternatives for silencing this warning are adding casts (which is generally seen as an ugly practice) or refactoring the enums to macro defines or a unified enum (which may be undesirable because of type safety in other parts of the code). Move the warning to W=2, where warnings that occur frequently but may be relevant should reside.
