Revision f4e7de63ab273b6a5e35c82eb4fc6363c855ddd4 authored by Doug Ledford on 23 April 2016, 00:14:58 UTC, committed by Doug Ledford on 23 April 2016, 00:26:44 UTC 
IB/core: Fix oops in ib_cache_gid_set_default_gid
 
When we fail to find the default gid index, we can't continue
processing in this routine or else we will pass a negative
index to later routines resulting in invalid memory access
attempts and a kernel oops.

Fixes: 03db3a2d81e6 (IB/core: Add RoCE GID table management)
