A bug report (https://bugzilla.kernel.org/show_bug.cgi?id=107071) noted
|
|
that the follwoing ip command is failing with v4.3:
|
|
|
|
$ ip route add 10.248.5.0/24 dev bond0.250 table vlan_250 src 10.248.5.154
|
|
RTNETLINK answers: Invalid argument
|
|
|
|
021dd3b8a142d changed the lookup of the given preferred source address to
|
|
use the table id passed in, but this assumes the local entries are in the
|
|
given table which is not necessarily true for non-VRF use cases. When
|
|
validating the preferred source fallback to the local table on failure.
|
|
|
|
Fixes: 021dd3b8a142d ("net: Add routes to the table associated with the device")

This is needed in v4.3.
