Florian Westphal says: ==================== tunnels: fix ipv4 pmtu icmp checksum The checksum of the generated ipv4 icmp pmtud message is only correct if the skb that causes the icmp error generation is linear. Fix this and add a selftest for this. ==================== Link: https://lore.kernel.org/r/20230803152653.29535-1-fw@strlen.de Signed-off-by: Jakub Kicinski <kuba@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.
