When processing a duplicate cookie-echo chunk, for case 'A' and 'B', after sctp_process_init for the new asoc, if auth is enabled for the cookie-ack chunk, the active key should also be initialized. Otherwise, the cookie-ack chunk made later can not be set with auth shkey properly, and a crash can even be caused by this, as after Commit1b1e0bc994("sctp: add refcnt support for sh_key"), sctp needs to hold the shkey when making control chunks.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
