From 811230cd853d62f09ed0addd0ce9a1b9b0e13fb5 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 28 Jan 2015 05:47:11 -0800 Subject: [PATCH] tcp: ipv4: initialize unicast_sock sk_pacing_rate When I added sk_pacing_rate field, I forgot to initialize its value in the per cpu unicast_sock used in ip_send_unicast_reply() This means that for sch_fq users, RST packets, or ACK packets sent on behalf of TIME_WAIT sockets might be sent to slowly or even dropped once we reach the per flow limit.
