Subject: [PATCH] Add fix to _do_madrpc to set the errno after umad_recv.
Date: Mon, 18 Feb 2013 14:10:29 -0800 [thread overview]
Message-ID: <5122A6D5.10400@oracle.com> (raw)
_do_madrpc() (in libibmad-1.3.3/src/rpc.c) sends the mad request through umad_send() and waits for a response from umad_recv() with the timeout passed by caller. Linux error
number sent by peer in 'status' is not copied over to the process/thread local 'errno'.
