- Resolves a spurious "Unknown discovery response content-type" error in client-go discovery requests by tolerating extra content-type parameters in API responses ([#117638](https://github.com/kubernetes/kubernetes/pull/117638), [@seans3](https://github.com/seans3)) [SIG API Machinery]

* `kubeadm init` can now omit the tainting of the master node if configured to do so in `kubeadm.yaml` using `noTaintMaster: true`. For example, uses can create a file with the content:

```
apiVersion: [kubeadm.k8s.io/v1alpha1](http://kubeadm.k8s.io/v1alpha1)
kind: MasterConfiguration
kubernetesVersion: v1.9.1
noTaintMaster: true
```

// The common components(signatureR, signatureS, hashedMessage, privateKey and // random number) each takes block size of bytes. The block size is different for // different curves and is set by canUseKDSA function. var params [4096]byte // Copy content into the parameter block. In the sign case, // we copy hashed message, private key and random number into // the parameter block. We skip the signature slots. p := params[:2*blockSize] p = appendBlock(p, blockSize, hashToBytes(c, hash)) p = appendBlock(p,...
