The Partially Reliable SCTP (PR-SCTP) extension defined in [RFC3758] provides a generic method for senders to abandon user messages. The decision to abandon a user message is sender side only, and the exact condition is called a "PR-SCTP policy". This patchset implements 3 policies: 1. Timed Reliability: This allows the sender to specify a timeout for a user message after which the SCTP stack abandons the user message. 2. Limited Retransmission Policy: Allows limitation of the number of retransmissions. 3. Priority Policy: Allows removal of lower-priority messages if space for higher-priority messages is needed in the send buffer. Patch 1-3 add some sockopts in sctp to set/get pr_sctp policy status. Patch 4-6 implement these 3 policies one by one. ==================== Acked-by: Marcelo Ricardo Leitner Signed-off-by: David S. Miller --- 4154cb40e71a7255bae0c67734fe85950c9254e5
