netvsc: fix use-after-free in netvsc_change_mtu()

2017-03-02T22:41:36+00:00

'nvdev' is freed in rndis_filter_device_remove -> netvsc_device_remove ->
free_netvsc_device, so we mustn't access it, before it's re-created in
rndis_filter_device_add -> netvsc_device_add.

Pull char/misc driver updates from Greg KH:
 "Here is the big char/misc driver patchset for 4.11-rc1.

  Lots of different driver subsystems updated here: rework for the
  hyperv subsystem to handle new platforms better, mei and w1 and extcon
  driver updates, as well as a number of other "minor" driver updates.

  All of these have been in linux-next for a while with no reported
  issues"

Remove it no longer used xmit_more in sendpacket in netvsc as well.

net-next: treewide use is_vlan_dev() helper function.

2017-02-06T21:33:29+00:00

This patch makes use of is_vlan_dev() function instead of flag
comparison which is exactly done by is_vlan_dev() helper function.

Drivers: hv: vmbus: finally fix hv_need_to_signal_on_read()

2017-01-31T09:59:48+00:00

Commit a389fcfd2cb5 ("Drivers: hv: vmbus: Fix signaling logic in
hv_need_to_signal_on_read()")
added the proper mb(), but removed the test "prev_write_sz < pending_sz"
when making the signal decision.

As a result, the guest can signal the host unnecessarily,
and then the host can throttle the guest because the host
thinks the guest is buggy or malicious; finally the user
running stress test can perceive intermittent freeze of
the guest.

This patch brings back the test, and properly handles the
in-place consumption APIs used by NetVSC (see get_next_pkt_raw(),
put_pkt_raw() and commit_rd_index()).

netvsc: call netif_receive_skb

2017-01-24T21:29:02+00:00

To improve performance, netvsc can call network stack directly and
avoid the local backlog queue. This is safe since incoming packets are
handled in softirq context already because the receive function
callback is called from a tasklet.
