[ Upstream commit 28427f368f0e08d504ed06e74bc7cc79d6d06511 ] Fix skb_ensure_writable() size. Don't use nft_tcp_header_pointer() to make it explicit that pointers point to the packet (not local buffer). Fixes: 99d1712bc41c ("netfilter: exthdr: tcp option set support") Fixes: 7890cbea66e7 ("netfilter: exthdr: add support for tcp option removal") Cc: stable@vger.kernel.org Signed-off-by: Xiao Liang <shaw.leon@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
