https://github.com/golang/go/issues/12262 . See #19254 for

ad07709461 Fully close sockets in kube-proxy 
We were trying to be clever and respect TCP's notion of half-open sockets, but
it causes leaks when we can't unblock io.Copy().  This fixes those leaks and
seems to follow most expectations.  I think we were just be too clever.

6bbf2aaab7 Refactor pkg/proxy/config's ServiceConfigHandler and EndpointsConfigHandler to have different update methods. 
Refactor `pkg/proxy/config`’s ServiceConfigHandler.OnUpdate and
EndpointsConfigHandler.OnUpdate to different method names as they have
different signatures.

This will let the new proxy
(https://github.com/GoogleCloudPlatform/kubernetes/issues/3760)
implement both interfaces.

Since we won’t need a separate loadbalancer structure (load balancing
is handled in the proxy rules), we will simply handle both event types
from the same object.

8ae203825b Implement multi-port endpoints 
Instead of endpoints being a flat list, it is now a list of "subsets"
where each is a struct of {Addresses, Ports}.  To generate the list of
endpoints you need to take union of the Cartesian products of the
subsets.  This is compact in the vast majority of cases, yet still
represents named ports and corner cases (e.g. each pod has a different
port number).

This also stores subsets in a deterministic order (sorted by hash) to
avoid spurious updates and comparison problems.

This is a fully compatible change - old objects and clients will
keepworking as long as they don't need the new functionality.

This is the prep for multi-port Services, which will add API to produce
endpoints in this new structure.

e8acfe5f81 change proxy to satisfy both gofmt 1.3 and 1.4 gofmt 
gofmt -s from 1.4  does not like
	for _ = range BLAH
it wants
	for range BLAH

But gofmt from 1.3 dies:
	./pkg/proxy/config/config.go:265:6: expected operand, found 'range'
	./pkg/proxy/config/config.go:268:3: expected '{', found 'EOF'

So instead, rewrite the code to make them both happy

411666decb Get rid of ServiceSpec.ProxyPort 
As far as I know, nobody uses it.  It was replaced by PublicIPs.  If I were
being very polite I would leave it in internal, but since I am 99.99% sure
nobody uses it, I am cutting it.  Let's argue about it.

3b5ea74a48 Fix a race in kube-proxy causing runaways 
It was an ABA problem where the proxy loop might see its own service as
"existing" when it had been destroyed and recreated (as in an update).

To prove this I added a counter of running ProxyLoop goroutines and check that
in tests.  If I undo my main change, the tests fail.  This makes the
proxier_test significantly slower (3 seconds vs 0.5 seconds).  Sorry.

295800201e Make pkg/proxy/config more like pkg/kubelet/config 
Split SourceAPI into two subobjects.

Parallel structure for endpoints, services will allow
changing to use generic code in pkg/client/cache/reflector.go.

Rename some funcs to be more like pkg/client/cache.

e045c6ce2f Split portals into host and container 
After this DNS is resolvable from the host, if the DNS server is targetted
explicitly.  This does NOT add the cluster DNS to the host's resolv.conf.  That
is a larger problem, with distro-specific tie-ins and circular deps.

c4e94efe16 Sticky Session Implementation 
- Added process to cleanup stale session affinity records
- Automatically set cloud provided load balancer for sticky session if the service requires it - Note, this only works on GCE right now.
- Changed sessionAffinityMap a map to pointers instead of structs to improve performance
- Commented out cookie and protocol from sessionAffinityDetail to avoid confusion as it is not yet implemented.

64f1084c1a Rename util.config.Watcher -> util.config.Broadcaster. 
Watch is a widely used term in the codebase, which doesn't capture
the key feature of this type: broadcasting a change to several
listeners.
