Hi Doug,
I am trying to rping server, but it fails when bound to any address other then IF_ANY.
# rping -s -a 102.1.1.129 -C1 -p 9999 -vd
created cm_id 0x23d7800
rdma_bind_addr: No such file or directory
destroy cm_id 0x23d7800
If bound to IF_ANY address, server starts but client fails to establish connection.
# rping -s -C1 -p 9999 -vvvd
created cm_id 0xc34800
rdma_bind_addr successful
rdma_listen
And the commit which introduced this regression is
commit abae1b71dd37bab506b14a6cf6ba7148f4d57232

IB/cma: cma_validate_port should verify the port and netdevice
Previously, cma_validate_port searched for GIDs in IB cache and then
tried to verify the found port. This could fail when there are
identical GIDs on both ports. In addition, netdevice should be taken
into account when searching the GID table.
Fixing cma_validate_port to search only the relevant port's cache
and netdevice.

The bug is easily reproducible with latest rc and breaks basic rdma functionality.
Since 4.4 is already in -rc8, can we have a quick fix.
Thanks,
