I think there's a problem in the dst refcounting in sctp_v4_get_dst()
There's a dst_entry struct that has >0 refcnt after running the testcase,
which makes it impossible to delete the loopback device, as that dst is
never freed.
I'll try to make a patch.
Are you looking at the second for loop there, which uses ip_route_output_key,
but discards the result if dst is already set? That does look a bit wonky, and
the same problem may exist in the ipv6 path. Let me know what the result is.
Yes, that was it. Did you receive the email I sent with the patch?
(I'm not seeing that message e.g. at spinics.net linux-sctp archive, so
just wondering if that email got lost somehow...)
I'll check the ipv6 case, did not try it yet.
