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

This will allow for kube-proxy to be run without `privileged` and
with only adding the capability `NET_ADMIN`.

Laszlo Janosi e466bdc67e Changes according to the approved KEP. SCTP is supported for HostPort and LoadBalancer. Alpha feature flag SCTPSupport controls the support of SCTP. Kube-proxy config parameter is removed. 2018-08-27 05:58:36 +00:00
Laszlo Janosi a6da2b1472 K8s SCTP support implementation for the first pull request
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

optimize ipvs get nodeIP

**What this PR does / why we need it**:

Optimize ipvs get nodeIP.

The original ipvs `NodeIPs` need first get all local type address to set1, then get address of dummy device `kube-ipvs0` to set2, then do diff of set1 and set2 to get local addresses we need.
This work gonna result in unnecessary resource consumption, especially for large cluster, will have lots address in dummy device `kube-ipvs0`. 

This pr optimized the workaround.

Not step into ipvs.CleanupLeftovers() if canUseIPVS's false

**What this PR does / why we need it**:
Earlier we decide whether we should clean up the left-over ipvs rules inside `ipvs.CleanupLeftovers()`, therefore we call function  `ipvs.CanUseIPVSProxier()` two times (and `GetModules()` two times).  Actually no need to step into `ipvs.CleanupLeftovers()` if `canUseIPVS` is false.

Fixes #65263

**Special notes for your reviewer**:
To fix the issue,   
use `activeBindAddrs` map which represents ip address successfully bind to DefaultDummyDevice in the round of sync  
use `currentBindAddrs` map which represents ip addresses bind to DefaultDummyDevice from the system  
create a function `cleanLegacyBindAddr` to unbind address which is in `currentBindAddrs` map but not in `activeBindAddrs` map
