2013-07-08[SCSI] qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()Bart Van Assche1-7/+7
Avoid that the fcport structure gets leaked if bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN, the fcport allocation succeeds and the !vha->flags.online branch is taken. This was detected by Coverity. However, Coverity does not recognize that all qla2x00_process_els() callers specify either FC_BSG_RPT_ELS or FC_BSG_HST_ELS_NOLOGIN in the field bsg_job->request->msgcode and that the value of that field is not modified inside that function. This results in a false positive report about a possible memory leak in an error path for bsg_job->request->msgcode values other than the two mentioned values. Make it easy for Coverity (and for humans) to recognize that there is no fcport leak in the error path by changing the bsg_job->request->msgcode == FC_BSG_HST_ELS_NOLOGIN test into bsg_job->request->msgcode != FC_BSG_RPT_ELS.

2013-06-20qla_target: remove qlt_check_fcport_existJörn Engel2-140/+17
Comment from original 2012 patch: In all our testing this function has never returned true. However, the dropping of hardware_lock necessary to call this function seems to cause a use-after-free we manage to hit rather frequently. Given this cost-benefit ratio, I'm willing to remove some 100 lines of code. And since the same problem exists around shutdown_sess and put_sess, this patch changes them from taking the hardware_lock to requiring the hardware_lock to be taken. In most cases the caller already had the lock and had to drop it for the called method to reacquire it. At best that hurts performance and in rare instances it causes races with fatal consequences. We dropped the original 2012 patch when upgrading our kernel and it took us nearly half a year to discover we still need it.

2013-06-14tcm_qla2xxx: Fix residual for underrun commands that failRoland Dreier1-1/+5
Suppose an initiator sends a DATA IN command with an allocation length shorter than the FC transfer length -- we get a target message like TARGET_CORE[qla2xxx]: Expected Transfer Length: 256 does not match SCSI CDB Length: 0 for SAM Opcode: 0x12 In that case, the target core adjusts the data_length and sets se_cmd->residual_count for the underrun. But now suppose that command fails and we end up in tcm_qla2xxx_queue_status() -- that function unconditionally overwrites residual_count with the already adjusted data_length, and the initiator will burp with a message like qla2xxx [0000:00:06.0]-301d:0: Dropped frame(s) detected (0x100 of 0x100 bytes). Fix this by adding on to the existing underflow residual count instead.

2013-05-12[SCSI] qla2xxx: Fix for locking issue between driver ISR and mailbox routinesgurinder.shergill@hp.com5-49/+27
The driver uses ha->mbx_cmd_flags variable to pass information between its ISR and mailbox routines, however, it does so without the protection of any locks. Under certain conditions, this can lead to multiple mailbox command completions being signaled, which, in turn, leads to a false mailbox timeout error for the subsequently issued mailbox command. The issue occurs frequently but intermittenly with the Qlogic 8GFC mezz card during card initialization, resulting in card initialization failure.

System crashes, in initiator mode operation, with qla2xxx_copy_atioqueues() in stack trace when firmware dump is attempted. Check for atio_q_length alone does not indicate if atio_ring is allocated, make explicit check of atio_ring to avoid the crash. Applicable to ISP24xx, ISP25xx, ISP81xx & ISP83xx line of HBAs.

2013-02-22[SCSI] qla2xxx: Don't process RSCNs for a vport on the same physical adapter.Chad Dupuis3-18/+33
Currently,the driver is processes RSCNs for each new NPIV ports that is created. Processing the RSCN includes a name server query to see what has changed at the name server side. The name server query is performed by the physical port and each virtual port on the physical adapter (since the RSCN is passed to each virtual port for processing). As the number of virtual ports being created increases, this causes a lot of traffic and busies the firmware. Processing the RSCN for a virtual port we already have a priori knowledge of is not necessary so check the 24-bit fabric ID of the RSCN entry and skip processing it if the RSCN is for a virtual port we already know about.

2013-02-22[SCSI] qla2xxx: Correct list-iteration bug in Report-ID Acquisition codes.Andrew Vasquez1-3/+8
Code in qla24xx_report_id_acquisition() incorrectly assumed that upon completion of list iteration (with no match), the 'pos' (vp) variable passed to list_for_each_entry() would be set to NULL. In this context, if the firmware were to return an unrecognized vp_idx, the follow-on assignments to vp-members could result in corruption of the structure.
