From 88f8c39912bc727e2531a5fab0361a1caa9d1a35 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Thu, 7 Nov 2019 18:29:52 +0000 Subject: [PATCH] ipv4: Fix table id reference in fib_sync_down_addr [ Upstream commit e0a312629fefa943534fc46f7bfbe6de3fdaf463 ] Hendrik reported routes in the main table using source address are not removed when the address is removed. The problem is that fib_sync_down_addr does not account for devices in the default VRF which are associated with the main table. Fix by updating the table id reference.
