This allows setting 2 and 4 byte quantities in the tcp option space. Main purpose is to allow native replacement for xt_TCPMSS to work around pmtu blackholes. Writes to kind and len are now allowed at the moment, it does not seem useful to do this as it causes corruption of the tcp option space. We can always lift this restriction later if a use-case appears. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
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.
