Both ip6_input_finish (non-GRO) and esp6_gro_receive (GRO) strip the IPv6 header without adjusting skb->csum accordingly. As a result CHECKSUM_COMPLETE breaks and "hw csum failure" is written to the kernel log by netdev_rx_csum_fault (dev.c). Fix skb->csum by substracting the checksum value of the pulled IPv6 header using a call to skb_postpull_rcsum. This affects both transport and tunnel modes. Note that the fix occurs far from the place that the header was pulled. This is based on existing code, see: ipv6_srh_rcv() in exthdrs.c and rawv6_rcv() in raw.c Signed-off-by: Yossi Kuperman <yossiku@mellanox.com> Signed-off-by: Ilan Tayari <ilant@mellanox.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> |

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.
