This patch is to fix the replay attack issue for strreset asoc requests. When a duplicated strreset asoc request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. But note that if the result saved in asoc is performed, the sender's next tsn and receiver's next tsn for the response chunk should be set. It's safe to get them from asoc. Because if it's changed, which means the peer has received the response already, the new response with wrong tsn won't be accepted by peer.

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.
