Fix routing from node to mesh
Recent changes in the routing configuration of OpenWrt broke source address selection, sometimes leading to the node trying to contact other addresses in the mesh network from the next-node address. Revert the problematic commits until this has been solved upstream.

-Subject: [PATCH] ipv6: Fixed source specific default route handling.
|
||||
-
|
||||
-If there are only IPv6 source specific default routes present, the
|
||||
-host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
|
||||
-calls ip6_route_output first, and given source address any, it fails,
|
||||
-and ip6_route_get_saddr is never called.
|
||||
-
|
||||
-The change is to use the ip6_route_get_saddr, even if the initial
|
||||
-ip6_route_output fails, and then doing ip6_route_output _again_ after
|
||||
-we have appropriate source address available.
|
||||
-
|
||||
-Note that this is '99% fix' to the problem; a correct fix would be to
|
||||
-do route lookups only within addrconf.c when picking a source address,
|
||||
-and never call ip6_route_output before source address has been
|
||||
-populated.
