Toshiaki Makita says: ==================== Fix vlan tag handling for vlan packets without ethernet headers Eric Dumazet reported syzbot found a new bug which leads to underflow of size argument of memmove(), causing crash[1]. This can be triggered by tun devices. The underflow happened because skb_vlan_untag() did not expect vlan packets without ethernet headers, and tun can produce such packets. I also checked vlan_insert_inner_tag() and found a similar bug. This series fixes these problems.

README
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.
