From ced68234b6a244355aeab07c2681bc49f695eaed Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Wed, 14 Mar 2018 12:49:19 -0400 Subject: sock: remove zerocopy sockopt restriction on closed tcp state Socket option SO_ZEROCOPY determines whether the kernel ignores or processes flag MSG_ZEROCOPY on subsequent send calls. This to avoid changing behavior for legacy processes. Limiting the state change to closed sockets is annoying with passive sockets and not necessary for correctness. Once created, zerocopy skbs are processed based on their private state, not this socket flag. Remove the constraint. Signed-off-by: Willem de Bruijn Signed-off-by: David S.
