Pull networking fixes from David Miller:

 1) kvaser CAN driver has fixed limits of some of it's table, validate
    that we won't exceed those limits at probe time.  Fix from Olivier
    Sobrie.

 2) Fix rtl8192ce disabling interrupts for too long, from Olivier
    Langlois.

 3) Fix botched shift in ath5k driver, from Dan Carpenter.

 4) Fix corruption of deferred packets in TIPC, from Erik Hugne.

 5) Fix newlink error path in macvlan driver, from Cong Wang.

 6) Fix netpoll deadlock in bonding, from Ding Tianhong.

 7) Handle GSO packets properly in forwarding path when fragmentation is
    necessary on egress, from Florian Westphal.

 8) Fix axienet build errors, from Michal Simek.

 9) Fix refcounting of ubufs on tx in vhost net driver, from Michael S
    Tsirkin.

10) Carrier status isn't set properly in hyperv driver, from Haiyang
    Zhang.

11) Missing pci_disable_device() in tulip_remove_one), from Ingo Molnar.

12) AF_PACKET qdisc bypass mode doesn't adhere to driver provided TX
    queue selection method.  Add a fallback method mechanism to fix this
    bug, from Daniel Borkmann.

13) Fix regression in link local route handling on GRE tunnels, from
    Nicolas Dichtel.

14) Bonding can assign dup aggregator IDs in some sequences of
    configuration, fix by making the allocation counter per-bond instead
    of global.  From Jiri Bohac.

15) sctp_connectx() needs compat translations, from Daniel Borkmann.

16) Fix of_mdio PHY interrupt parsing, from Ben Dooks

netdevice: add queue selection fallback handler for ndo_select_queue

2014-02-17T05:36:34+00:00

Add a new argument for ndo_select_queue() callback that passes a
fallback handler. This gets invoked through netdev_pick_tx();
fallback handler is currently __netdev_pick_tx() as most drivers
invoke this function within their customized implementation in
case for skbs that don't need any special handling. This fallback
handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).

This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

net: core: explicitly select a txq before doing l2 forwarding

2014-01-10T18:23:08+00:00

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:

- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
  instead of lower device which misses the necessary txq synchronization for
  lower device such as txq stopping or frozen required by dev watchdog or
  control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
  watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
  when tso is disabled for lower device.

Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.

With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.

In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.
