open netlink socket with CLOEXEC #71
Description
The netlink socket is opened without the CLOEXEC flag. Rust standard library sets CLOEXEC for all the stuff it opens. Maybe it would make sense to do it in neli as well to avoid accidental leaks when creating child processes?
Should be easy to change in src/socket.rs NlSocket::new but it does have some backward compatibility concerns..
