Why is ib_sa_get_mcmember_rec being called? Or is this issue separate from what
udaddy is showing?
The IPOIB port space allows for UD interoperability between IPoIB and
RDMA-CM based apps. For that end, among other params such as the mgid
derivation, the qkey used for the UD QP must be the same. To achieve
that, a query on the broadcast group is done to the core multicast
data-base to retrieve the associated record from which the qkey is
extracted. When the port goes down, this db is being flushed and
ib_sa_get_mcmember_rec returns EADDRNOTAVAIL which is exactly what
udaddy is getting (you can also get it with mckey).
Can you determine what call in the kernel is actually failing during the bind?
mcast_find being called from ib_sa_get_mcmember_rec
Or.
