scsi: use 64-bit LUNs

2014-07-17T20:07:37+00:00

The SCSI standard defines 64-bit values for LUNs, and large arrays
employing large or hierarchical LUN numbers become more and more
common.

So update the linux SCSI stack to use 64-bit LUN numbers.

bnx2fc: Improve stats update mechanism

Its due to the fact that we call a potentially sleeping function from the bnx2fc
rcv path with preemption disabled (via the get_cpu call embedded in the per-cpu
variable stats lookup in bnx2fc_l2_rcv_thread.

Easy enough fix, we can just move the stats collection later in the function
where we are sure we won't preempt or sleep.  This also allows us to not have to
enable pre-emption when doing a per-cpu lookup, since we're certain not to get
rescheduled.

bnx2fc: do not scan uninitialized lists in case of error.

2014-06-25T11:29:30+00:00

In case of of error, the bnx2fc_cmd_mgr_alloc() function will call
the bnx2fc_cmd_mgr_free() to perform the cleanup.
The problem is that in one case the latter may try to scan
some not-yet initialized lists, resulting in a kernel panic.

This patch prevents this from happening by freeing the lists
before calling bnx2fc_cmd_mgr_free().

Pull SCSI updates from James Bottomley:
 "This patch consists of the usual driver updates (qla2xxx, qla4xxx,
  lpfc, be2iscsi, fnic, ufs, NCR5380) The NCR5380 is the addition to
  maintained status of a long neglected driver for older hardware.  In
  addition there are a lot of minor fixes and cleanups and some more
  updates to make scsi mq ready"

bnx2fc: fix memory leak and potential NULL pointer dereference.

2014-05-19T17:29:57+00:00

If bnx2fc_allocate_hash_table() for some reasons fails, it is possible that the
hash_tbl_segments or the hash_tbl_pbl pointers are NULL.
In this case bnx2fc_free_hash_table() will panic the system.

this patch also fixes a memory leak, the hash_tbl_segments pointer was never
freed.
