Subject: [PATCH linux-next 0/4] fix possile NULL pointer dereference in ndo_get_iflink callback functions


The four callback functions deferference the pointers without test. 
As ipoib_get_iflink failed, it is a good reason to fix the other three
functions. Those functions will return zero on error, as valid ifindex
greater than zero.

I understand that those simple patches should be emerged into a single
patch. However, those files have be maintained by different maintainers.
So, I split it for review. It also will be convenient to remove one or
more patches with the rest not be affected.

Honggang Li (4):
  infiniband/ipoib: fix possible NULL pointer dereference in
 ipoib_get_iflink
  ipvlan: fix possible NULL pointer dereference in ipvlan_get_iflink
  macvlan: fix possible NULL pointer dereference in macvlan_dev_get_iflink
  net/dsa: fix possible NULL pointer dereference in dsa_slave_get_iflink
