[ Upstream commit 46e16d4b956867013e0bbd7f2bad206f4aa55752 ] When processing a duplicate cookie-echo chunk, for case 'D', sctp will not process the param from this chunk. It means old asoc has nothing to be updated, and the new temp asoc doesn't have the complete info. So there's no reason to use the new asoc when creating the cookie-ack chunk. Otherwise, like when auth is enabled for cookie-ack, the chunk can not be set with auth, and it will definitely be dropped by peer. This issue is there since very beginning, and we fix it by using the old asoc 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.
