OpenVPN is an open source VPN daemon
c654225701
This patch introduces a tiny netlink interface, optimized for the openvpn use case. It basically exposes all those operations that are currently handled by directly calling the /sbin/ip command (or even ifconfig/route, if configured). By using netlink, openvpn won't need to spawn new processes when configuring the tun interface or routes. This new approach will also allow openvpn to be granted CAP_NET_ADMIN and be able to properly work even though it dropped the root privileges (currently handled via workarounds). By moving this logic into the sitnl module, tun.c and route.c also benefit from some code simplification Signed-off-by: Antonio Quartulli <a@unstable.cc> Acked-by: Arne Schwabe <arne@rfc2549.org> Message-Id: <20181219050118.6568-3-a@unstable.cc> URL: https://www.mail-archive.com/openvpn-devel@lists.sourceforge.net/msg18030.html Signed-off-by: Gert Doering <gert@greenie.muc.de> |
