From 2dc4e9e88cfcc38454d52b01ed3422238c134003 Mon Sep 17 00:00:00 2001 From: Paul Blakey Date: Sun, 17 Oct 2021 14:58:51 +0300 Subject: [PATCH] net/sched: act_ct: Fix byte count on fragmented packets First fragmented packets (frag offset = 0) byte len is zeroed when stolen by ip_defrag(). And since act_ct update the stats only afterwards (at end of execute), bytes aren't correctly accounted for such packets. To fix this, move stats update to start of action execute.
