This package is an initial implementation of something that can read netfilter and iptables rules from the Linux kernel without needing to shell out to an external utility; it speaks directly to the kernel using syscalls and parses the data returned. Currently this is read-only since it only knows how to parse a subset of the available data. Signed-off-by: Andrew Dunham <andrew@tailscale.com> Change-Id: Iccadf5dcc081b73268d8ccf8884c24eb6a6f1ff5
