With refcnt support for sh_key, chunks auth sh_keys can be decided before enqueuing it. Changing the active key later will not affect the chunks already enqueued. Furthermore, this is necessary when adding the support for authinfo for sendmsg in next patch. Note that struct sctp_chunk can't be grown due to that performance drop issue on slow cpu, so it just reuses head_skb memory for shkey in sctp_chunk.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
