Hi, This is v3 of a net series that fixes several related issues in ovpn's UDP endpoint and route-cache handling. This version was rebased on top of net and includes suggestions from Sabrina. The former patch 5/5 was dropped from this series and will be sent as RFC on netdev, where it is more appropriate since it involves changes broader than ovpn alone.
This series preserves IPv6 scope IDs supplied through netlink, handles unspecified source addresses correctly, invalidates cached routes when mutable socket route inputs change and avoids in-place updates of RCU-published peer binds. 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, Ralf Lici Mandelbit Srl --- Changes since v2 https://lore.kernel.org/openvpn-devel/[email protected]/ - Split former patch 4/5 into three separate patches. (Sabrina) - Dropped former patch 5/5 from this series as it introduces IPv6 routing changes and needs to be discussed as an RFC on netdev. (Sabrina) Changes since v1 https://lore.kernel.org/openvpn-devel/[email protected] - Patch 5/5: add memory barriers around IPv6 FIB generation reads to avoid reordering on weakly ordered architectures (Sashiko). Ralf Lici (6): ovpn: preserve IPv6 scope id for netlink peer endpoints ovpn: skip UDP source validation for unspecified addresses ovpn: track UDP socket route key for peer dst cache ovpn: validate peer state before caching UDP dst ovpn: replace bind when learning local endpoint ovpn: replace bind when clearing stale local source drivers/net/ovpn/netlink.c | 6 ++ drivers/net/ovpn/peer.c | 44 ++++++----- drivers/net/ovpn/peer.h | 19 ++++- drivers/net/ovpn/udp.c | 193 +++++++++++++++++++++++++++++++++++++-------- 4 files changed, 206 insertions(+), 56 deletions(-) base-commit: 1b78070aaef63512688aebfbc82365ef9d6660f1 -- 2.55.0 _______________________________________________ Openvpn-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/openvpn-devel
