Xin Long f30ea678a2 sctp: ensure sk_state is set to CLOSED if hashing fails in sctp_listen_start 
[ Upstream commit 4d5c70e615 ]

If hashing fails in sctp_listen_start(), the socket remains in the
LISTENING state, even though it was not added to the hash table.
This can lead to a scenario where a socket appears to be listening
without actually being accessible.

This patch ensures that if the hashing operation fails, the sk_state
is set back to CLOSED before returning an error.

Note that there is no need to undo the autobind operation if hashing
fails, as the bind port can still be used for next listen() call on
the same socket.

Fixes: 76c6d988ae ("sctp: add sock_reuseport for the sock in __sctp_hash_endpoint")

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.
