Casey Callendrello 017f57a6b0 proxy: add some useful metrics 
This adds some useful metrics around pending changes and last successful
sync time.

The goal is for administrators to be able to alert on proxies that, for
whatever reason, are quite stale.

Merge pull request #75265 from JacobTanenbaum/ClearExternalIPs 
Clear conntrack entries on 0 -> 1 endpoint transition with externalIPs
 2019-03-18 11:06:23 -07:00
Jacob Tanenbaum 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

Tim Hockin 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.

clusterIP but not for externalIP of the service. This change adds

Jacob Tanenbaum 144280e7a7 Correctly Clear conntrack entrty on endpoint changes when using nodeport 
When using NodePort to connect to an endpoint using UDP, if the endpoint is deleted on
restoration of the endpoint traffic does not flow. This happens because conntrack holds
the state of the connection and the proxy does not correctly clear the conntrack entry
for the stale endpoint.

Introduced a new function to conntrack ClearEntriesForPortNAT that uses the endpointIP
and NodePort to remove the stale conntrack entry and allow traffic to resume when
the endpoint is restored.

Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
