Output of expressions might be larger than one single register, this might clobber existing data. Reset tracking for all destination registers that required to store the expression output. This patch adds three new helper functions: - nft_reg_track_update: cancel previous register tracking and update it. - nft_reg_track_cancel: cancel any previous register tracking info. - __nft_reg_track_cancel: cancel only one single register tracking info. Partial register clobbering detection is also supported by checking the .num_reg field which describes the number of register that are used. This patch updates the following expressions: - meta_bridge - bitwise - byteorder - meta - payload to use these helper functions. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.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.
