| |
Hi:
I found a bug when remove an ip address which is referenced by a routing entry.
step to reproduce:
ip li add type dummy ip li set dummy0 up ip ad add 10.0.0.1/24 dev dummy0 ip ad add 10.0.0.2/24 dev dummy0 ip ro add default via 10.0.0.2/24 ip ad del 10.0.0.2/24 dev dummy0
after deleting the secondary ip address, the routing entry still pointing to 10.0.0.2
# ip ro default via 10.0.0.2 dev dummy0 10.0.0.0/24 dev dummy0 proto kernel scope link src 10.0.0.1
but actually, kernel considers the default route is directly connected.
# ip ro get 1.1.1.1 1.1.1.1 dev dummy0 src 10.0.0.1 cache
