This patch is to fix the replay attack issue for strreset and addstrm in requests. When a duplicated strreset in or addstrm in 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. For strreset in or addstrm in request, if the receiver side processes it successfully, a strreset out or addstrm out request(as a response for that request) will be sent back to peer. reconf_time will retransmit the out request even if it's lost. So when receiving a duplicated strreset in or addstrm in request and it's result was performed, it shouldn't reply this request, but drop it instead.

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.
