Mahesh Bandewar says: ==================== ipvlan: packet scrub While crossing namespace boundary IPvlan aggressively scrubs packets. This is creating problems. First thing is that scrubbing changes the packet type in skb meta-data to PACKET_HOST. This causes erroneous packet delivery when dev_forward_skb() has already marked the packet type as OTHER_HOST. On the egress side scrubbing just before calling dev_queue_xmit() creates another set of problems. Scrubbing remove skb->sk so the prio update gets missed and more seriously, socket back-pressure fails making TSQ not function correctly. The first patch in the series just reverts the earlier change which was adding a mac-check, but that is unnecessary if packet_type that dev_forward_skb() has set is honored. The second path removes two of the scrubs which are causing problems described above. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
