[ovs-dev] [PATCH v3] classifier: Prevent tries vs n_tries race leading to NULL dereference.

Currently classifier tries and n_tries can be updated not atomically, there is a race condition which can lead to NULL dereference. The race can happen when main thread updates a classifier tries and n_tries in classifier_set_prefix_fields() and at the same time revalidator or handler thread try

[ovs-dev] [PATCHv5] userspace: Add conntrack timeout policy support.

Commit 1f1613183733 ("ct-dpif, dpif-netlink: Add conntrack timeout policy support") adds conntrack timeout policy for kernel datapath. This patch enables support for the userspace datapath. I tested using the 'make check-system-userspace' which checks the timeout policies for ICMP and UDP cases.

When generating SB records that have tunnel_keys (e.g., Datapath, Port_Binding, Multicast_Group) ovn-northd tries to reuse the tunnel_key value from the original SB record, if any available. However, there's no check for tunnel_keys that would conflict with newly allocated keys for new records.
