Subject: [patch] RDMA/ocrdma: off by one in ocrdma_query_gid()
Date: Thu, 14 Jun 2012 21:36:09 +0300 [thread overview]
Message-ID: <20120614183609.GE6383@elgon.mountain> (raw)
The dev->sgid_tbl[] array is allocated in ocrdma_alloc_resources(). It
has OCRDMA_MAX_SGID elements so the test here is off by one.
