net: Eliminate NETIF_F_GEN_CSUM and NETIF_F_V[46]_CSUM

2015-12-15T21:50:20+00:00

These netif flags are unnecessary convolutions. It is more
straightforward to just use NETIF_F_HW_CSUM, NETIF_F_IP_CSUM,
and NETIF_F_IPV6_CSUM directly.

This patch also:
    - Cleans up can_checksum_protocol
    - Simplifies netdev_intersect_features

net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK

2015-12-15T21:50:08+00:00

The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
    use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

ipv4: Pass struct net into ip_defrag and ip_check_defrag

2015-10-13T02:44:16+00:00

The function ip_defrag is called on both the input and the output
paths of the networking stack.  In particular conntrack when it is
tracking outbound packets from the local machine calls ip_defrag.

So add a struct net parameter and stop making ip_defrag guess which
network namespace it needs to defragment packets in.

macvlan: Don't segment multiple tagged packets on macvlan device

2015-08-03T21:24:49+00:00

Macvlan/macvtap devices don't need to segment multiple tagged packets
since the lower devices can segment them.

macvlan: Propagate promiscuity setting to lower devices.

2015-05-04T04:14:13+00:00

When a macvlan device is placed in promiscuous mode, it currently
just sets it's multicast mask to permissive, but doesn't change
the state of the lower device.  As a result, not all multicast
traffic can be received on such device.  Additionally, none of
a vlan traffic can be received on such device as well.
This patch propagates the promiscuous mode setting to lower device
so that lower device may receive all packets that macvlan may
be interested in.

net: Kill dev_rebuild_header

Now that there are no more users kill dev_rebuild_header and all of it's
implementations.

This is long overdue.

If device is already used as an ipvlan port then refuse to
use it as a macvlan port at early stage of port creation.
