63c01133f8 proxy/userspace: add dcbw and danwinship to OWNERS approvers
Per recommendation of @thockin:

https://github.com/kubernetes/kubernetes/pull/71735#pullrequestreview-189515580

IMO this code is as dead as it could be. The only significant user is OpenShift as far as I know. I'd rather never touch it again, but I know that is not realistic.

Also, it seems like maybe this could be broken into a couple commits for easier review?

I raised some questions about this design, but I think you should add yourselves as approvers in OWNERS for this subdir. If it evolves, I will lose context on the impl. I don't think it is covered by e2e, either (more argument for breaking it to a separate repo and having its own e2e tests)

8cf0076e23 proxy/userspace: respect minSyncInterval and simplify locking
The userspace proxy does not have any ratelimiting and when many
services are used will hammer iptables every time a service or
endpoint change occurs. Instead build up a map of changed
services and process all those changes at once instead of each
time an event comes in. This also ensures that no long-running
processing happens in the same call chain as the OnService*
calls as this blocks other handlers attached to the proxy's
parent ServiceConfig object for long periods of time.

Locking can also now be simplified as the only accesses to the
proxy's serviceMap happen from syncProxyRules(). So instead of
locking in many functions just lock once in syncProxyRules()
like the other proxies do.

cf7225f561 proxy/userspace: replace IsServiceIPSet() with ShouldSkipService()
Keeps things consistent with iptables/IPVS proxies. Proxies don't
handle ServiceTypeExternalName even if the ClusterIP is set.

ddab79a233 proxy/userspace: add proxy shutdown function and use in testcases

4b07f80d20 proxy: consolidate ServicesHandler/EndpointsHandler into ProxyProvider
Proxies should be able to cleanly figure out when endpoints have been synced,
so make all ProxyProviders also implement EndpointsHandler and pass those
through to loadbalancers when required.

c3548165d5 Clear conntrack entries on 0 -> 1 endpoint transition with externalIPs
As part of the endpoint creation process when going from 0 -> 1 conntrack entries
are cleared. This is to prevent an existing conntrack entry from preventing traffic
to the service. Currently the system ignores the existance of the services external IP
addresses, which exposes that errant behavior

This adds the externalIP addresses of udp services to the list of conntrack entries that
get cleared. Allowing traffic to flow

de25d6cb95 Kube-proxy: REJECT LB IPs with no endpoints
We REJECT every other case.  Close this FIXME.

To get this to work in all cases, we have to process service in
filter.INPUT, since LB IPS might be manged as local addresses.
