vmlinux.lds.h: Add .symtab, .strtab, and .shstrtab to ELF_DETAILS When linking vmlinux with LLD, the synthetic sections .symtab, .strtab, and .shstrtab are listed as orphaned. Add them to the ELF_DETAILS section so there will be no warnings when --orphan-handling=warn is used more widely. (They are added above comment as it is the more common order[1].) ld.lld: warning: <internal>:(.symtab) is being placed in '.symtab' ld.lld: warning: <internal>:(.shstrtab) is being placed in '.shstrtab' ld.lld: warning: <internal>:(.strtab) is being placed in '.strtab' [1] https://lore.kernel.org/lkml/20200622224928.o2a7jkq33guxf...@google.com/ Reported-by: Fangrui Song <mask...@google.com> Signed-off-by: Kees Cook <keesc...@chromium.org> Signed-off-by: Ingo Molnar <mi...@kernel.org> Cc: linux-a...@vger.kernel.org Link: https://lore.kernel.org/r/20200821194310.3089815-6-keesc...@chromium.org --- include/asm-generic/vmlinux.lds.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/include/asm-generic/vmlinux.lds.h b/include/asm-generic/vmlinux.lds.h index cadcbc3..98d013d 100644 --- a/include/asm-generic/vmlinux.lds.h +++ b/include/asm-generic/vmlinux.lds.h @@ -823,7 +823,10 @@ /* Required sections not related to debugging. */ #define ELF_DETAILS \ - .comment 0 : { *(.comment) } + .comment 0 : { *(.comment) } \ + .symtab 0 : { *(.symtab) } \ + .strtab 0 : { *(.strtab) } \ + .shstrtab 0 : { *(.shstrtab) } #ifdef CONFIG_GENERIC_BUG #define BUG_TABLE \
