2017-02-01net: reduce skb_warn_bad_offload() noiseEric Dumazet1-3/+9
Dmitry reported warnings occurring in __skb_gso_segment() [1] All SKB_GSO_DODGY producers can allow user space to feed packets that trigger the current check. We could prevent them from doing so, rejecting packets, but this might add regressions to existing programs. It turns out our SKB_GSO_DODGY handlers properly set up checksum information that is needed anyway when packets needs to be segmented. By checking again skb_needs_check() after skb_mac_gso_segment(), we should remove these pesky warnings, at a very minor cost.

2017-02-01rtnetlink: Handle IFLA_MASTER parameter when processing rtnl_newlinkTheuns Verwoerd1-1/+6
Allow a master interface to be specified as one of the parameters when creating a new interface via rtnl_newlink. Previously this would require invoking interface creation, waiting for it to complete, and then separately binding that new interface to a master. In particular, this is used when creating a macvlan child interface for VRRP in a VRF configuration, allowing the interface creator to specify directly what master interface should be inherited by the child, without having to deal with asynchronous complications and potential race conditions.
