commit 6613b6173dee098997229caf1f3b961c49da75e6 upstream. When first DCCP packet is SYNC or SYNCACK, we insert a new conntrack that has an un-initialized timeout value, i.e. such entry could be reaped at any time. Mark them as INVALID and only ignore SYNC/SYNCACK when connection had an old state.

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.
