From 2d94b20b95b009eec1a267dcf026b01af627c0cd Mon Sep 17 00:00:00 2001 From: Brett Mastbergen Date: Tue, 8 Dec 2020 16:39:24 -0500 Subject: netfilter: nft_ct: Remove confirmation check for NFT_CT_ID Since commit 656c8e9cc1ba ("netfilter: conntrack: Use consistent ct id hash calculation") the ct id will not change from initialization to confirmation. Removing the confirmation check allows for things like adding an element to a 'typeof ct id' set in prerouting upon reception of the first packet of a new connection, and then being able to reference that set consistently both before and after the connection is confirmed.
