Currently mutex_is_held can only test locks in the that are global since it takes no arguments. This prevents rhashtable from being used in places where locks are lock, e.g., per-namespace locks. This patch adds a parent field to mutex_is_held and rhashtable_params so that local locks can be used (and tested). Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

Large receive offloading is known to cause problems if received packets are passed to other host. Therefore the kernel disables it by calling dev_disable_lro() whenever a network device is enslaved in a bridge or forwarding is enabled for it (or globally). For virtual devices we need to disable LRO on the underlying physical device (which is actually receiving the packets). Current dev_disable_lro() code handles this propagation for a vlan (including 802.1ad nested vlan), macvlan or a vlan on top of a macvlan. It doesn't handle other stacked devices and their combinations, in particular propagation from a bond to its slaves which often causes problems in virtualization setups. As we now have generic data structures describing the upper-lower device relationship, dev_disable_lro() can be generalized to disable LRO also for all lower devices (if any) once it is disabled for the device itself. For bonding and teaming devices, it is necessary to disable LRO not only on current slaves at the moment when dev_disable_lro() is called but also on any slave (port) added later. v2: use lower device links for all devices (including vlan and macvlan) Signed-off-by: NMichal Kubecek <mkubecek@suse.cz> Acked-by: NVeaceslav Falico <vfalico@gmail.com> Signed-off-by: NDavid S.

This patch fixes two issues after using iovec iterators: - vlan_offset should be initialized to zero, otherwise unexpected offset will be used in skb_copy_datagram_iter() - advance iovec iterator when vnet_hdr_sz is greater than sizeof(gso), this is the case when mergeable rx buffer were enabled for a virt guest.

Instead of calling fou and gue functions directly from ip_tunnel use ops for these that were previously registered. This patch adds the logic to add and remove encapsulation operations for ip_tunnel, and modified fou (and gue) to register with ip_tunnels. This patch also addresses a circular dependency between ip_tunnel and fou that was causing link errors when CONFIG_NET_IP_TUNNEL=y and CONFIG_NET_FOU=m.
