RequiredIPVSKernelModulesAvailable warning confuses users suggesting
that the IPVS proxier will not be used, which is not always the case.
Made the warning message less confusing:
[WARNING RequiredIPVSKernelModulesAvailable]:
The IPVS proxier may not be used because the following required kernel
modules are not loaded: [ip_vs_rr ip_vs_wrr ip_vs_sh]
or no builtin kernel ipvs support was found: map[ip_vs_wrr:{}
ip_vs_sh:{} nf_conntrack_ipv4:{} ip_vs:{} ip_vs_rr:{}].
However, these modules may be loaded automatically by kube-proxy for you
if they are available on your system.
To verify IPVS support:
Run "lsmod | grep 'ip_vs\|nf_conntrack'" and verify each of the above
modules are listed.
If they are not listed, you can use the following methods to load them:
1. For each missing module run 'modprobe $modulename' (e.g., 'modprobe
ip_vs', 'modprobe ip_vs_rr', ...)
2. If 'modprobe $modulename' returns an error, you will need to install
the missing module support for your kernel.
Fixes: kubernetes/kubeadm#975
- 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

The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master

Implement delete real server for fakeIPVS and add UTs
**What this PR does / why we need it**:
* Implement DeleteRealServer() for FakeIPVS because ipvs/proxier needs it.
* Add UTs - Since there are some real logics in fakeIPVS interface, it's important to add some UTs which can help avoiding some mistakes. Sadly, there is already a bug :(

bazel: build/test almost everything
**What this PR does / why we need it**: Miscellaneous cleanups and bug fixes. The main motivating idea here was to make `bazel build //...` and `bazel test //...` mostly work. (There's a few reasons these still don't work, but we're a lot closer.)
