From: Jeff Mahoney <jeffm@suse.com>
Subject: openslp: Use TCPDIAG for checking listeners
References: bnc#601002
The use of /proc/net/tcp is deprecated and can cause performance issues on
large systems. The issue is that there are a great many locks that must
be claimed and released in order to produce the contents of the proc file.
The replacement mechanism is to use the INETDIAG/TCPDIAG interface to
get the results. This has the advantage of using in-kernel filtering as
well as a binary interface so that the parsing of the proc file is
unnecessary.
Support is limited to TCP so the use of /proc/net/udp is still required.
If for whatever reason the netlink connection is lost and can't be
re-established, we fall back to reading /proc/net/tcp until the daemon
is restarted.
