7f6fbc4482 Drop broken/no-op proxyconfig.EndpointsHandler implementations 
Because the proxy.Provider interface included
proxyconfig.EndpointsHandler, all the backends needed to
implement its methods. But iptables, ipvs, and winkernel implemented
them as no-ops, and metaproxier had an implementation that wouldn't
actually work (because it couldn't handle Services with no active
Endpoints).

Since Endpoints processing in kube-proxy is deprecated (and can't be
re-enabled unless you're using a backend that doesn't support
EndpointSlice), remove proxyconfig.EndpointsHandler from the
definition of proxy.Provider and drop all the useless implementations.

f3708fa016 Do not attempt to overwrite higher system (sysctl) values 
With this commit kube-proxy accepts current system values (retrieved by sysctl) which are higher than the internally known and expected values.
The code change was mistakenly created as PR in the k3s project (see https://github.com/k3s-io/k3s/pull/3505). 
A real life use case is described in Rancher issue https://github.com/rancher/rancher/issues/33360.

When Kubernetes runs on a Node which itself is a container (e.g. LXC), and the value is changed on the (LXC) host, kube-proxy then fails at the next start as it does not recognize the current value and attempts to overwrite the current value with the previously known one. This result in:

```
I0624 07:38:23.053960      54 conntrack.go:103] Set sysctl 'net/netfilter/nf_conntrack_max' to 524288
F0624 07:38:23.053999      54 server.go:495] open /proc/sys/net/netfilter/nf_conntrack_max: permission denied
```

However a sysctl overwrite only makes sense if the current value is lower than the previously known and expected value. If the value was increased on the host, that shouldn't really bother kube-proxy and just go on with it.

kube-proxy detect IP family based on nodeIP
 2020-06-18 19:04:21 -07:00

56df70b639 kube-proxy detect IP family based on nodeIP 
We were detecting the IP family that kube-proxy should use
based on the bind address, however, this is not valid when
using an unspecified address, because on those cases
kube-proxy adopts the IP family of the address reported
in the Node API object.

The IP family will be determined by the nodeIP used by the proxier
The order of precedence is:
1. config.bindAddress if bindAddress is not 0.0.0.0 or ::
2. the primary IP from the Node object, if set
3. if no IP is found it defaults to 127.0.0.1 and IPv4
