Fri, 25 Sep 2026 23:46:32 +0200

random: vDSO: avoid call to memset() when zeroing reserved parameterAfter a recent change in LLVM [1], builds with the random vDSOimplementation, such as PowerPC and RISC-V, fail when checking the vDSO: arch/powerpc/kernel/vdso/vdso32.so.dbg: dynamic relocations are not supported arch/riscv/kernel/vdso/vdso.so.dbg: dynamic relocations are not supportedmemset() is now generated when zeroing params->reserved for some buildsbecause LLVM has an optimization (now run in more instances) that canrecognize at compile time when it is assigning a static value to acontiguous area of memory and turn that into a call to memset(). Bothclang and GCC assume memset() is always available [2].Clang has an internal fiddly hook, -max-store-memset, which we can setto a high number, to disable generating out of line memset calls [3].Similarly, GCC has -finline-stringops=memset to do the same [4], shouldthis issue ever hit future version of GCC. While these options wouldn'tmake sense for normal kernel code, it is fine for the extremely limitedand intentionally compact vDSO code.Link: https://github.com/llvm/llvm-project/commit/90cebef1411617fc3eedd359bdf00cb44b1c2439 [1]Link: https://gcc.gnu.org/onlinedocs/gcc-16.2.0/gcc/Standards.html#index-ffreestanding [2]Link: https://github.com/llvm/llvm-project/commit/b28eeb28bea39148738dc375e8a97072a1907e64 [3]Link: https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-finline-stringops [4]Closes: https://github.com/ClangBuiltLinux/linux/issues/2183Cc: stable@vger.kernel.org # v6.12+Signed-off-by: Nathan Chancellor Signed-off-by: Jason A.

Sat, 27 Apr 2024 16:55:02 +0200

kbuild: use $(src) instead of $(srctree)/$(src) for source directoryKbuild conventionally uses $(obj)/ for generated files, and $(src)/ forchecked-in source files. It is merely a convention without any functionaldifference. In fact, $(obj) and $(src) are exactly the same, as definedin scripts/Makefile.build: src := $(obj)When the kernel is built in a separate output directory, $(src) doesnot accurately reflect the source directory location. While Kbuildresolves this discrepancy by specifying VPATH=$(srctree) to search forsource files, it does not cover all cases. For example, when adding aheader search path for local headers, -I$(srctree)/$(src) is typicallypassed to the compiler.This introduces inconsistency between upstream and downstream Makefilesbecause $(src) is used instead of $(srctree)/$(src) for the latter.To address this inconsistency, this commit changes the semantics of$(src) so that it always points to the directory in the source tree.Going forward, the variables used in Makefiles will have the followingmeanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source treeConsequently, $(srctree)/$(src) in upstream Makefiles need to be replacedwith $(src).Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux/arch/powerpc/kernel/vdso/Makefile

Fri, 10 Mar 2023 20:07:50 +0100

vdso: Improve cmd_vdso_check to check all dynamic relocationsThe actual intention is that no dynamic relocation exists in the VDSO. Forthis the VDSO build validates that the resulting .so file does not have anyrelocations which are specified via $(ARCH_REL_TYPE_ABS) per architecture,which is fragile as e.g. ARM64 lacks an entry for R_AARCH64_RELATIVE. Asideof that ARCH_REL_TYPE_ABS is a misnomer as it checks for relativerelocations too.However, some GNU ld ports produce unneeded R_*_NONE relocation entries. Ifa port fails to determine the exact .rel[a].dyn size, the trailing zerosbecome R_*_NONE relocations. E.g. ld's powerpc port recently fixedhttps://sourceware.org/bugzilla/show_bug.cgi?id=29540). R_*_NONE aregenerally a no-op in the dynamic loaders. So just ignore them.Remove the ARCH_REL_TYPE_ABS defines and just validate that the resulting.so file does not contain any R_* relocation entries except R_*_NONE.Signed-off-by: Fangrui Song Signed-off-by: Thomas Gleixner Tested-by: Vincenzo Frascino # for aarch64Reviewed-by: Christophe Leroy Reviewed-by: Vincenzo Frascino # for vDSO, aarch64Acked-by: Michael Ellerman (powerpc)Link: https://lore.kernel.org/r/20230310190750.3323802-1-maskray@google.com List of files: /linux/arch/powerpc/kernel/vdso/Makefile
