[PATCH 1/8] qla2xxx: klocwork - Array index may go out of bound

[Nilesh Javali]

Klocwork reports array 'vha->host_str' of size 16
may use index value(s) 16..19.
Use snprintf instead of sprintf.

Please add BUG_ON(!cur_dsd) above the first cur_dsd dereference instead 
of making the above change. The above change hides a bug. Hiding bugs 
doesn't help anyone.

Thanks for the review.
We can prevent the crash and notify the occurrence of this
rare case by adding warn_on like,

+       WARN_ON_ONCE(!cur_dsd);
+       if (cur_dsd) {
+               cur_dsd->address = 0;
+               cur_dsd->length = 0;
+               cur_dsd++;
+       }
        cmd_pkt->control_flags |= cpu_to_le16(CF_DATA_SEG_DESCR_ENABLE);
        return 0;
 }

Thanks,
Nilesh

I think there is a much better solution: drop the new "if (cur_dsd) {" 
test and instead add the following code:

  	/* No data transfer */

  		cmd_pkt->byte_count = cpu_to_le32(0);
  		return 0;
  	}

Is the above change sufficient to suppress the Klocwork warning?

Thanks,

This looks good and does not generate any new klocwork warning.
I will re-send the series with this change included.

[PATCH 3/8] qla2xxx: klocwork - Check for a valid fcport pointer

[Nilesh Javali]

Klocwork reported warning of null pointer may be dereferenced.
The routine exits when sa_ctl is NULL and fcport is allocated after
the exit call thus causing NULL fcport pointer to dereference at the
time of exit.

Add a check for a valid fcport pointer at the time of exit.

Please change the "goto done" statements that occur before fcport is set 
into "return rval" instead of making the above change.

From: Quinn Tran <qutran@marvell.com>

Klocwork warning: Buffer Overflow - Array Index Out of Bounds

Driver uses fc_els_flogi to calculate size of buffer.
The actual buffer is nested inside of fc_els_flogi
which is smaller.

Replace structure name to allow proper size calculation.

Please use ARRAY_SIZE() instead of open-coding it.
