From: Allison Henderson <[email protected]> Hi all,
This is subset 3 of the larger RDS-TCP patch series I posted last Oct. The greater series aims to correct multiple rds-tcp issues that can cause dropped or out of sequence messages. I've broken it down into smaller sets to make reviews more manageable. In this set, we introduce extension headers for byte accounting and fix several RDS/TCP protocol issues including message preservation during connection transitions and multipath lane handling. The entire set can be viewed in the rfc here: https://lore.kernel.org/netdev/[email protected]/ Questions, comments, flames appreciated! Thanks!
