The DSA layer frees the original skb when an xmit function returns NULL, meaning an error occurred. But if the tagging code copied the original skb, it is responsible of freeing the copy if an error occurs. The ksz tagging code currently has two issues: if skb_put_padto fails, the skb copy is not freed, and the original skb will be freed twice. To fix that, move skb_put_padto inside both branches of the skb_tailroom condition, before freeing the original skb, and free the copy on error.

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.
