From e5eefe77435a8958681a92546c46e3c05b93ac7b Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Tue, 15 Mar 2022 01:07:02 +0100 Subject: tcp: Refactor to use events instead of states, split out spliced implementation Using events and flags instead of states makes the implementation much more straightforward: actions are mostly centered on events that occurred on the connection rather than states. An example is given by the ESTABLISHED_SOCK_FIN_SENT and FIN_WAIT_1_SOCK_FIN abominations: we don't actually care about which side started closing the connection to handle closing of connection halves. Split out the spliced implementation, as it has very little in common with the "regular" TCP path. Refactor things here and there to improve clarity. Add helpers to trace where resets and flag settings come from. No functional changes intended.
