[Openvpn-devel] [PATCH ovpn net 0/5] ovpn: fix UDP route cache and endpoint handling

Hi,

This series fixes several related issues in ovpn's UDP endpoint and
route-cache handling.

It preserves IPv6 scope IDs supplied through netlink, handles
unspecified source addresses correctly, invalidates cached routes when
mutable socket route inputs change, avoids in-place updates of
RCU-published peer binds, and prevents stale IPv6 routes from being
cached across FIB updates.

Support for honoring UDP sockets bound to a device or local address will
follow separately for net-next, after these route-cache fixes are
available there.

Cheers,
