Toke Høiland-Jørgensen 9fc0420864 libbpf: Don't crash on object files with no symbol tables ... [ Upstream commit 03e601f48b ] If libbpf encounters an ELF file that has been stripped of its symbol table, it will crash in bpf_object__add_programs() when trying to dereference the obj->efile.symbols pointer. Fix this by erroring out of bpf_object__elf_collect() if it is not able able to find the symbol table. v2: - Move check into bpf_object__elf_collect() and add nice error message Fixes: 6245947c1b ("libbpf: Allow gaps in BPF program sections to support overriden weak functions") Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Link: https://lore.kernel.org/bpf/20210901114812.204720-1-toke@redhat.com Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-11-18 19:16:22 +01:00
