From 4af4e406b16ef791aa069930768b495358033708 Mon Sep 17 00:00:00 2001 From: Stephen Suryaputra Date: Thu, 4 Jul 2019 11:39:51 +0800 Subject: [PATCH] ipv4: Use return value of inet_iif() for __raw_v4_lookup in the while loop [ Upstream commit 38c73529de13e1e10914de7030b659a2f8b01c3b ] In commit 19e4e768064a8 ("ipv4: Fix raw socket lookup for local traffic"), the dif argument to __raw_v4_lookup() is coming from the returned value of inet_iif() but the change was done only for the first lookup. Subsequent lookups in the while loop still use skb->dev->ifIndex.
