3b70b66e - selinux: move genheaders to security/selinux/

Fri, 06 Sep 2024 17:29:14 +0000

selinux: move genheaders to security/selinux/This tool is only used in security/selinux/Makefile.Move it to security/selinux/ so that 'make clean' can clean it up.Please note 'make clean' does not clean scripts/ because tools underscripts/ are often used for external module builds. Obviously, genheadersis not the case here.Signed-off-by: Masahiro Yamada Signed-off-by: Paul Moore List of files: /linux-6.15/scripts/remove-stale-files

4e9903b0 - fortify: refactor test_fortify Makefile to fix some build problems

Sat, 27 Jul 2024 15:02:36 +0000

fortify: refactor test_fortify Makefile to fix some build problemsThere are some issues in the test_fortify Makefile code.Problem 1: cc-disable-warning invokes compiler dozens of timesTo see how many times the cc-disable-warning is evaluated, changethis code: $(call cc-disable-warning,fortify-source)to: $(call cc-disable-warning,$(shell touch /tmp/fortify-$$$$)fortify-source)Then, build the kernel with CONFIG_FORTIFY_SOURCE=y. You will see alarge number of '/tmp/fortify-' files created: $ ls -1 /tmp/fortify-* | wc 80 80 1600This means the compiler was invoked 80 times just for checking the-Wno-fortify-source flag support.$(call cc-disable-warning,fortify-source) should be added to a simplevariable instead of a recursive variable.Problem 2: do not recompile string.o when the test code is updatedThe test cases are independent of the kernel. However, when the testcode is updated, $(obj)/string.o is rebuilt and vmlinux is relinkeddue to this dependency: $(obj)/string.o: $(obj)/$(TEST_FORTIFY_LOG)always-y is suitable for building the log files.Problem 3: redundant code clean-files += $(addsuffix .o, $(TEST_FORTIFY_LOGS))... is unneeded because the top Makefile globally cleans *.o files.This commit fixes these issues and makes the code readable.Signed-off-by: Masahiro Yamada Link: https://lore.kernel.org/r/20240727150302.1823750-2-masahiroy@kernel.orgSigned-off-by: Kees Cook List of files: /linux-6.15/scripts/remove-stale-files

5e9e95cc - kbuild: implement CONFIG_TRIM_UNUSED_KSYMS without recursion

Sun, 11 Jun 2023 15:50:57 +0000

kbuild: implement CONFIG_TRIM_UNUSED_KSYMS without recursionWhen CONFIG_TRIM_UNUSED_KSYMS is enabled, Kbuild recursively traversesthe directory tree to determine which EXPORT_SYMBOL to trim. If anEXPORT_SYMBOL turns out to be unused by anyone, Kbuild begins thesecond traverse, where some source files are recompiled with theirEXPORT_SYMBOL() tuned into a no-op.Linus stated negative opinions about this slowness in commits: - 5cf0fd591f2e ("Kbuild: disable TRIM_UNUSED_KSYMS option") - a555bdd0c58c ("Kbuild: enable TRIM_UNUSED_KSYMS again, with some guarding")We can do this better now. The final data structures of EXPORT_SYMBOLare generated by the modpost stage, so modpost can selectively emitKSYMTAB entries that are really used by modules.Commit f73edc8951b2 ("kbuild: unify two modpost invocations") is anotherground-work to do this in a one-pass algorithm. With the list of modules,modpost sets sym->used if it is used by a module. modpost emits KSYMTABonly for symbols with sym->used==true.BTW, Nicolas explained why the trimming was implemented with recursion: https://lore.kernel.org/all/2o2rpn97-79nq-p7s2-nq5-8p83391473r@syhkavp.arg/Actually, we never achieved that level of optimization where the chainreaction of trimming comes into play because: - CONFIG_LTO_CLANG cannot remove any unused symbols - CONFIG_LD_DEAD_CODE_DATA_ELIMINATION is enabled only for vmlinux, but not modulesIf deeper trimming is required, we need to revisit this, but I guessthat is unlikely to happen.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/remove-stale-files

kbuild: do not put .scmversion into the source tarball.scmversion is used by (src)rpm-pkg and deb-pkg to carry KERNELRELEASE.In fact, deb-pkg does not rely on it any more because the generateddebian/rules specifies KERNELRELEASE from the command line.Do likwise for (src)rpm-pkg, and remove this feature.For the same reason, you do not need to save LOCALVERSION in thespec file.Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/scripts/remove-stale-files

1476fee5 - kbuild: add a script to remove stale generated files

Sun, 25 Apr 2021 07:07:12 +0000

kbuild: add a script to remove stale generated filesWe maintain .gitignore and Makefiles so build artifacts are properlyignored by Git, and cleaned up by 'make clean'. However, the code isalways changing; generated files are often moved to another directory,or removed when they become unnecessary. Such garbage files tend to beleft over in the source tree because people usually git-pull withoutcleaning the tree.This is not only the noise for 'git status', but also a build issuein some cases.One solution is to remove a stale file like commit 223c24a7dba9 ("kbuild:Automatically remove stale file") did. Such workaroundshould be removed after a while, but we forget about that if we scatterthe workaround code in random places.So, this commit adds a new script to collect cleanings of stale files.As a start point, move the code in arch/arm/boot/compressed/Makefileinto this script.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/remove-stale-files
