[RFC net-next af_unix v1 0/1] Allow delivery of SIGURG on AF_UNIX streams socket

[rao.shoaib@oracle.com]

From: Rao Shoaib <rao.shoaib@oracle.com>

We have a use case where thousands of processes connect locally to a
database and issue queries that are serviced by a pool of threads.
Communication is done over AF_UNIX sockets. Currently, there is no way
for the submitter to signal the servicing thread about an urgent
condition such as abandoning the query. This patch addresses that
requirement by adding support for MSG_OOB flag for AF_UNIX sockets.
On receipt of such a flag, the kernel sends a SIGURG to the peer.
