with HTTPS clients is an important defense against potential security problems. [We
track][tls_history] the dynamic TLS ecosystem and adjust OkHttp to improve connectivity and
security.

OkHttp uses your platform's built-in TLS implementation. On Java platforms OkHttp also supports

// produces an incorrect value it fails with a hard error.
//
// erasureSelfTest tries to catch any issue in the erasure implementation
// early instead of silently corrupting data.
func erasureSelfTest() {
	// Approx runtime ~1ms
	var testConfigs [][2]uint8
	for total := uint8(4); total < 16; total++ {
		for data := total / 2; data < total; data++ {
			parity := total - data

The **TLS certificates** are **associated with a domain name**, not with an IP address.

So, to renew the certificates, the renewal program needs to **prove** to the authority (Let's Encrypt) that it indeed **"owns" and controls that domain**.

To do that, and to accommodate different application needs, there are several ways it can do it. Some popular ways are:

     * manage that 4 byte header specifically and therefore the initial
     * bufferIndex, and thus headerStart, would be 4).(NOTE: If one where
     * looking for a way to improve perfomance this is precisly what you
     * would want to do as the jcifs.smb1.netbios.SocketXxxputStream classes
     * arraycopy all data read or written into a new buffer shifted over 4!)
     */

* Allow for watching objects larger than 1MB given etcd accepts objects of size up to 1.5MB ([#72053](https://github.com/kubernetes/kubernetes/pull/72053), [@wojtek-t](https://github.com/wojtek-t))
* Improve efficiency of preemption logic in clusters with many pending pods. ([#72895](https://github.com/kubernetes/kubernetes/pull/72895), [@bsalamat](https://github.com/bsalamat))
