Hello Nicholas,
This is a semi-automatic email about new static checker warnings.
The patch 962f988d031f: "qla2xxx: Add LLD target-mode infrastructure
for >= 24xx series" from Mar 8, 2012, leads to the following Smatch
complaint:
drivers/scsi/qla2xxx/qla_target.c:2873 qla_tgt_abort_task()
error: we previously assumed 'sess' could be null (see line 2870)
drivers/scsi/qla2xxx/qla_target.c
2869 sess = ha->tgt_ops->find_sess_by_loop_id(vha, loop_id);
2870 if (sess == NULL) {
^^^^^^^^^^^^
Test.
2871 ql_dbg(ql_dbg_tgt_mgt, vha, 0xe129, "qla_target(%d): task abort for unexisting "
2872 "session\n", vha->vp_idx);
2873 res = qla_tgt_sched_sess_work(sess->tgt, QLA_TGT_SESS_WORK_ABORT,
^^^^^^^^^
NULL dereference.
2874 iocb, sizeof(*iocb));
2875 if (res != 0)
regards,
dan carpenter
