From: Denys Zagorui <dzagorui@cisco.com> stable inclusion from stable-v6.6.11 commit 0b39339f8afa7549125323072a1a29a237ca5c29 bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit ebc8484d0e6da9e6c9e8cfa1f40bf94e9c6fc512 ] This cast was made by purpose for older libbpf where the bpf_object_skeleton field is void * instead of const void * to eliminate a warning (as i understand -Wincompatible-pointer-types-discards-qualifiers) but this cast introduces another warning (-Wcast-qual) for libbpf where data field is const void * It makes sense for bpftool to be in sync with libbpf from kernel sources Signed-off-by: Denys Zagorui <dzagorui@cisco.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20230907090210.968612-1-dzagorui@cisco.com Stable-dep-of: 23671f4dfd10 ("bpftool: Align output skeleton ELF code") Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: ZhangPeng <zhangpeng362@huawei.com> --- tools/bpf/bpftool/gen.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/bpf/bpftool/gen.c b/tools/bpf/bpftool/gen.c index 2883660d6b67..04c47745b3ea 100644 --- a/tools/bpf/bpftool/gen.c +++ b/tools/bpf/bpftool/gen.c @@ -1209,7 +1209,7 @@ static int do_skeleton(int argc, char **argv) codegen("\ \n\ \n\ - s->data = (void *)%2$s__elf_bytes(&s->data_sz); \n\ + s->data = %2$s__elf_bytes(&s->data_sz); \n\ \n\ obj->skeleton = s; \n\ return 0; \n\ -- 2.25.1
