* net: sctp: probe: allow more advanced ingress filtering by markDaniel Borkmann2013-09-041-5/+13
| | | | | | | | | | | | This is a follow-up commit for commit b1dcdc68b1f4 ("net: tcp_probe: allow more advanced ingress filtering by mark") that allows for advanced SCTP probe module filtering based on skb mark (for a more detailed description and advantages using mark, refer to b1dcdc68b1f4). The current option to filter by a given port is still being preserved. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S.

* net: neighbour: Remove CONFIG_ARPDTim Gardner2013-09-044-22/+0
| | | | | | | | | | | | | | | | | | | | | | | This config option is superfluous in that it only guards a call to neigh_app_ns(). Enabling CONFIG_ARPD by default has no change in behavior. There will now be call to __neigh_notify() for each ARP resolution, which has no impact unless there is a user space daemon waiting to receive the notification, i.e., the case for which CONFIG_ARPD was designed anyways.

* virtio-net: Set RXCSUM feature if GUEST_CSUM is availableThomas Huth2013-09-041-0/+2
| | | | | | | | | | | | | | If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest does not have to calculate the checksums on all received packets. This is pretty much the same feature as RX checksum offloading on real network cards, so the virtio-net driver should report this by setting the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she can see whether the virtio-net interface has to calculate RX checksums or not.

* Merge branch 'addr_assign_type'David S. Miller2013-09-0412-11/+26
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bjørn Mork says: ==================== net: set addr_assign_type when inheriting a dev_addr Copying the dev_addr from a parent device is an operation common to a number of drivers. The addr_assign_type should be updated accordingly, either by reusing the value from the source device or explicitly indicating that the address is stolen by setting addr_assign_type to NET_ADDR_STOLEN. This patch set adds a helper copying both the dev_addr and the addr_assign_type, and use this helper in drivers which don't currently set the addr_assign_type. Using NET_ADDR_STOLEN might be more appropriate in some of these cases. Please let me know, and I'll update the patch accordingly. Changes in v2: - assuming addr_len == ETH_ALEN to allow optimized memcpy - dropped the vt6656 patch due to addr_len being unset in that driver ==================== Signed-off-by: David S.
