- Apply "terminate-peers-on-quit.patch" to introduce the new
internal PRIV_SOCK_QUIT command which vsftpd sends to privileged
parent processes to properly shut down the TLS connection in case
we've received QUIT from the session client. This change avoids
misleading error messages in the servers log file. [bsc#1199250]
