Revision 963916fdb3e5ad4af57ac959b5a03bf23f7568ca authored by Kalderon, Michal on 06 July 2017, 20:22:11 UTC, committed by Doug Ledford on 20 July 2017, 15:24:13 UTC
Once in_dev_get is called to receive in_device pointer, the
in_device reference counter is increased, but if there are
no ipv4 addresses configured on the net-device the ifa_list
will be null, resulting in a flow that doesn't call in_dev_put
to decrease the ref_cnt.
This was exposed when running RoCE over ipv6 without any ipv4
addresses configured

Fixes: commit 8e3867310c90 ("IB/cma: Fix a race condition in iboe_addr_get_sgid()")
