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: 5b79bcdf ("bpftool: Don't crash on missing jited insns or ksyms") Fixes: cae73f23 ("bpftool: use bpf_program__get_prog_info_linear() in prog.c:do_dump()") Signed-off-by:
