ipv6: del unreachable route when an addr is deleted on lo
[ Upstream commit 64c6d08e6490fb18cea09bb03686c149946bd818 ]
When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), two routes
are added:
- one in the local table:
local 2002::1 via :: dev lo proto none metric 0
- one the in main table (for the prefix):
unreachable 2002::1 dev lo proto kernel metric 256 error -101
When the address is deleted, the route inserted in the main table remains
because we use rt6_lookup(), which returns NULL when dst->error is set, which
is the case here! Thus, it is better to use ip6_route_lookup() to avoid this
kind of filter.
