Hello Nicholas Bellinger,
This is a semi-automatic email about new static checker warnings.
The patch 2c0532cbbbb5: "qla2xxx: Add LLD target-mode infrastructure
for >= 24xx series" from May 3, 2012, leads to the following Smatch
complaint:
drivers/scsi/qla2xxx/qla_target.c:2965 qlt_abort_task()
error: we previously assumed 'sess' could be null (see line 2958)
drivers/scsi/qla2xxx/qla_target.c
2957 sess = ha->tgt.tgt_ops->find_sess_by_loop_id(vha, loop_id);
2958 if (sess == NULL) {
^^^^^^^^^^^^
New check.
2959 ql_dbg(ql_dbg_tgt_mgt, vha, 0xf025,
2960 "qla_target(%d): task abort for unexisting "
2961 "session\n", vha->vp_idx);
2962 res = qlt_sched_sess_work(ha->tgt.qla_tgt,
2963 QLA_TGT_SESS_WORK_ABORT, iocb, sizeof(*iocb));
2964 if (res != 0)
2965 sess->tgt->tm_to_unknown = 1;
^^^^^^^^^
New dereference.
2966
2967 return res;
regards,
dan carpenter
