If anyone has any objections, please let me know. ------------------ From: Pablo Neira Ayuso [ Upstream commit d2dc429ecb4e79ad164028d965c00f689e6f6d06 ] If element timeout is unset and set provides no default timeout, the element expiration is silently ignored, reject this instead to let user know this is unsupported. Also prepare for supporting timeout that never expire, where zero timeout and expiration must be also rejected.
