Merge tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-genericPull compiler version requirement update from Arnd Bergmann: "Require gcc-8 and binutils-2.30 x86 already uses gcc-8 as the minimum version, this changes all other architectures to the same version. gcc-8 is used is Debian 10 and Red Hat Enterprise Linux 8, both of which are still supported, and binutils 2.30 is the oldest corresponding version on those. Ubuntu Pro 18.04 and SUSE Linux Enterprise Server 15 both use gcc-7 as the system compiler but additionally include toolchains that remain supported. With the new minimum toolchain versions, a number of workarounds for older versions can be dropped, in particular on x86_64 and arm64. Importantly, the updated compiler version allows removing two of the five remaining gcc plugins, as support for sancov and structeak features is already included in modern compiler versions. I tried collecting the known changes that are possible based on the new toolchain version, but expect that more cleanups will be possible. Since this touches multiple architectures, I merged the patches through the asm-generic tree."* tag 'gcc-minimum-version-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: Makefile.kcov: apply needed compiler option unconditionally in CFLAGS_KCOV Documentation: update binutils-2.30 version reference gcc-plugins: remove SANCOV gcc plugin Kbuild: remove structleak gcc plugin arm64: drop binutils version checks raid6: skip avx512 checks kbuild: require gcc-8 and binutils-2.30 List of files: /linux/lib/tests/stackinit_kunit.c

d985e4399adffb58e10b38dbb5479ef29d53cde6 - kunit/stackinit: Use fill byte different from Clang i386 pattern

Tue, 04 Mar 2025 23:56:11 +0100

kunit/stackinit: Use fill byte different from Clang i386 patternThe byte initialization values used with -ftrivial-auto-var-init=pattern(CONFIG_INIT_STACK_ALL_PATTERN=y) depends on the compiler, architecture,and byte position relative to struct member types. On i386 with Clang,this includes the 0xFF value, which means it looks like nothing changesbetween the leaf byte filling pass and the expected "stack wiping"pass of the stackinit test.Use the byte fill value of 0x99 instead, fixing the test for i386 Clangbuilds.Reported-by: ernsteiswuerfelCloses: https://github.com/ClangBuiltLinux/linux/issues/2071Fixes: 8c30d32b1a32 ("lib/test_stackinit: Handle Clang auto-initialization pattern")Tested-by: Nathan Chancellor Link: https://lore.kernel.org/r/20250304225606.work.030-kees@kernel.orgSigned-off-by: Kees Cook List of files: /linux/lib/tests/stackinit_kunit.c
