Turns out the xlated program instructions can also be missing if kptr_restrict sysctl is set. This means that the previous fix to check the jited_prog_insns pointer was insufficient; add another check of the xlated_prog_insns pointer as well. Fixes:5b79bcdf03("bpftool: Don't crash on missing jited insns or ksyms") Fixes:cae73f2339("bpftool: use bpf_program__get_prog_info_linear() in prog.c:do_dump()") Signed-off-by: Toke Høiland-Jørgensen <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Reviewed-by: Quentin Monnet <[email protected]> Link: https://lore.kernel.org/bpf/[email protected]
