Florian Westphal 77b337196a netfilter: conntrack: don't refresh sctp entries in closed state
Vivek Thrivikraman reported:
 An SCTP server application which is accessed continuously by client
 application.
 When the session disconnects the client retries to establish a connection.
 After restart of SCTP server application the session is not established
 because of stale conntrack entry with connection state CLOSED as below.

 (removing this entry manually established new connection):

 sctp 9 CLOSED src=10.141.189.233 [..]  [ASSURED]

Just skip timeout update of closed entries, we don't want them to
stay around forever.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
