rdma:smoke failure in NetBSD if RDMA_OPTION_ID_REUSEADDR is not defined

2015-04-16T06:39:23+00:00

By the change http://review.gluster.org/#/c/10014/, we only set
reuseaddr option if the macro RDMA_OPTION_ID_REUSEADDR is defined in
rdmacma.h . The variable optval is only used in the section where we
use conditional compiling based on the macro. So if the macro is not
defined, then compiler will throw a warning for optval.

the remote addr is always setting as the first address of
the vector.

rdma: pre-register iobuf_pool with rdma devices.

2015-03-27T11:34:08+00:00

        Back port pf : http://review.gluster.org/9506

registring buffers with rdma device is a time consuming
operation. So performing registration in code path will
decrease the performance.
Using a pre registered memory will give a bettor performance,
ie, register iobuf_pool during rdma initialization. For
dynamically created arena, we can register with all the
device.

rdma:read multiple wr from cq and ack them in one call

2015-03-27T11:33:47+00:00

        Back port of : http://review.gluster.org/9329

we are reading one work completion request at a time
from cq, though we can read multiple work completion
requests from cq. Also we can acknowledge them in
one call itself. Both will give a better performance
because of less mutual exclusion locks are being performed.

ibv_post-send will allow to send multiple work request
in a single call posting as linked list.

So if the payload count > 1, we can perform the data
operation in a single call to ibv_post_send.

        Back port of : http://review.gluster.org/9321

For a vectored read with payload count>1 will make two read
requests and to hold that a single contiguous memory is allocated.
So after completing the read request, instead of sending as vector
we will aggregate all the reads one.

rdma:vectored write fails for rdma.

2015-01-07T05:41:17+00:00

        Backport of http://review.gluster.org/9247

For rdma write with payload count greater than one
will fail due to insuffient memory to hold the
buffers in rpc transport layer. It was expecting
only one vector in payload, So it can only able
to decode the first iovec from payload, and the
rest will be discarded.

Thnaks to Raghavendra Gowdappa for fixing the
same.
