Xin Long 2d4ddd5e36 sctp: set chunk transport correctly when it's a new asoc 
[ Upstream commit 4ff40b8626 ]

In the paths:

  sctp_sf_do_unexpected_init() ->
    sctp_make_init_ack()
  sctp_sf_do_dupcook_a/b()() ->
    sctp_sf_do_5_1D_ce()

The new chunk 'retval' transport is set from the incoming chunk 'chunk'
transport. However, 'retval' transport belong to the new asoc, which
is a different one from 'chunk' transport's asoc.

It will cause that the 'retval' chunk gets set with a wrong transport.
Later when sending it and because of Commit b9fd683982 ("sctp: add
sctp_packet_singleton"), sctp_packet_singleton() will set some fields,
like vtag to 'retval' chunk from that wrong transport's asoc.

This patch is to fix it by setting 'retval' transport correctly which
belongs to the right asoc in sctp_make_init_ack() and
sctp_sf_do_5_1D_ce().

Fixes: b9fd683982 ("sctp: add sctp_packet_singleton")

README 

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.
