Given bpf fs wasn't mounted before, then mount it with stricter permissions than the default ones (777). Also add few other options as discussed in #10793 such as `nosuid,nodev,noexec` though at least from bpf fs side these are ignored. Fixes: #10793 Reported-by: Travis Glenn Hansen <travisghansen@yahoo.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
