rpc/rpc-transport: fix frame-loss during rdma-reads.

2010-09-24T14:10:27+00:00

- total no of rdma reads in progress was tracked using refcount of post
    (refcount = total rdma reads + 1). However doing rdma_post_unref _after_
    rdma_do_reads, can result in race condition between execution of
    rdma_post_unref and procedure handling rdma read completion. This makes
    it impossible to find out whether the current rdma read was the last
    rdma-read being done in procedure handling rdma read-completion.
    The fix to this should either do rdma_post_unref before posting an rdma
    read or use another variable to track the number of rdma-reads.
    This patch implements second method.

rpc-transport/rdma: fix memory corruptions caused by rdma.

2010-09-07T18:48:01+00:00

- disconnect notification should be sent before unrefing transport,
    since transport might be freed when unrefed.
  - set trans->listener. This member is used by rpcsvc to decide whether
    a listener or a new connection is dead.

- An ioq entry is added to ioq-list only when it is not processed due to lack
   of quota. For all other cases, it should be freed to avoid memory leak.
