示例1: standaloneTLSTicketKeyRotation
// standaloneTLSTicketKeyRotation governs over the array of TLS ticket keys used to de/crypt TLS tickets.
// It periodically sets a new ticket key as the first one, used to encrypt (and decrypt),
// pushing any old ticket keys to the back, where they are considered for decryption only.
//
// Lack of entropy for the very first ticket key results in the feature being disabled (as does Go),
// later lack of entropy temporarily disables ticket key rotation.
// Old ticket keys are still phased out, though.
//
// Stops the ticker when returning.
func standaloneTLSTicketKeyRotation(c *tls.Config, ticker *time.Ticker, exitChan chan struct{}) {
defer ticker.Stop()
// The entire page should be marked as sticky, but Go cannot do that
// without resorting to syscall#Mlock. And, we don't have madvise (for NODUMP), too. ☹
