From c199105d154e029cd8c94cccd35bd073e64acc45 Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Wed, 3 Sep 2014 12:01:18 -0400 Subject: net-timestamp: only report sw timestamp if reporting bit is set The timestamping API has separate bits for generating and reporting timestamps. A software timestamp should only be reported for a packet when the packet has the relevant generation flag (SKBTX_..) set and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set. The second check was accidentally removed. Reinstitute the original behavior. Tested: Without this patch, Documentation/networking/txtimestamp reports timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set. After the patch, it only reports them when the flag is set.
