Permanent target failures are non-retryable and should be classified as TARGET_ERROR; otherwise dm-multipath will retry an IO request that will always fail at the target. A SCSI command that fails with ILLEGAL_REQUEST sense and Additional sense 0x20, 0x21, 0x24 or 0x26 represents a permanent TARGET_ERROR. Signed-off-by:

The provisioning_mode parameter in sysfs did not get updated in the SD_LBP_DISABLE case. Make sure the provisioning mode is always set correctly. Signed-off-by:

The error reported up the stack for a discard failure did not clearly indicate that the command was processed and subsequently failed by the target device. Return -EREMOTEIO so multipathing does not classify this condition as a path failure. Signed-off-by:

In some configurations user may not have boot targets configured. In such cases the debug messages printed out by driver look like some kind of failure happening. However this could be a valid case, so modified the messages to appear as warning messages versus failure messages. Signed-off-by:

qla4xxx_verify_boot_idx can falsely report a DDB to be boot target if ha->pri_ddb_idx and ha->sec_ddb_idx are not initialized correctly. What this could cause is if there is DDB entry in FLash at index 0, then qla4xxx_verify_boot_idx would return wrong result as ha->pri_ddb_idx is not set correctly. Fixed the qla4xxx_get_boot_info to set the ha->pri_ddb_idx and ha->sec_ddb_idx correctly. Signed-off-by:

Fix the un-necessary wait for completion of a sendtarget on an invalid DDB entry. The state of an invalid DDB entry is 0 (unassigned) This will also avoid the delays during system boot. Signed-off-by:

While we wait for GPN_FT response, if the ctlr link goes down, the stack generates a completion for GPN_FT with error FC_EXCH_CLOSED, and reports a discovery error. Discovery is not retried in this case, and rightly so. However, the 'pending' flag stays set, which does not allow subsequent discovery to succeed as GPN_FT will never be issued. Fix it by clearing the pending flag when the discovery fails due to GPN_FT failure. Signed-off-by:

Adding and removing the host into the zone causes this panic. BUG: unable to handle kernel NULL pointer dereference at 00000000000000a0 IP: [<ffffffffa0491707>] fc_exch_recv+0xc57/0xe70 [libfc] Call Trace: [<ffffffffa050e04b>] bnx2fc_l2_rcv_thread+0x37b/0x430 [bnx2fc] [<ffffffffa050dcd0>] ? bnx2fc_l2_rcv_thread+0x0/0x430 [bnx2fc] [<ffffffff81090886>] kthread+0x96/0xa0 [<ffffffff8100c14a>] child_rip+0xa/0x20 [<ffffffff810907f0>] ? kthread+0x0/0xa0 [<ffffffff8100c140>] ? child_rip+0x0/0x20 During fc_exch_reset, the active exchanges are aborted and the exch is deleted. As part of processing ABTS response, due to 'ep' being NULL, any access to ep in fc_exch_recv_bls() causes this panic. Fixed to access 'ep' only if non-NULL. Reviewed-by:

The reference counting was necessary on these instances because it was possible for NPIV ports to be destroyed after the N_Port. A previous patch ensures that all NPIV ports are destroyed before the N_Port making the need to track references on the interface unnecessary. Signed-off-by:

Currently all port deletion is routed though the FCoE workqueue (fcoe_wq). When fc_remove_host is called on an N_Port (for example, from fcoe_destroy) the vports are queued into a FC Transport workqueue. fc_remove_host flushes that queue and each vport is passed to fcoe's fcoe_vport_destroy, which simply queues the associated fcoe_ports for later deletion. This queue cannot be flushed within the N_Ports destroy path because of circular locking issues. The result is that the NPIV ports are destroyed after the N_Port, which is reverse of how they are created. This quirk causes fcoe to keep references on the fcoe_interface shared by each of these ports (N_Port and NPIV). Changing the ordering such that NPIV ports are destroyed before the N_Port will allow us to remove reference counting on the fcoe_interface instances. This patch simply allows fcoe_vport_destory to destroy NPIV ports without deferring them to a workqueue context. This ensures that when fc_remove_host is called the NPIV ports will be destroyed first before the N_Port and allows reference counting on the fcoe's fcoe_interface to be remove in a later patch.

The label implies that it should be called when there is 'nomod.' I read that to mean that the module reference 'get' failed. However, it's only called when the module reference 'get' succeeded. I think it makes more sense to name the label, 'out_putmod' since it should be called when we need to 'put' the module reference taken in the routine before returning. Signed-off-by:

This is more of a debug statement. As a KERN_ERR we generate log entries anytime any netdev goes up or down, so when booting there are notification log entries for all system interfaces including 'lo'. This is too much. Let's just log when necessary. Signed-off-by:

A device logout sent in the delete path of a fcport would clear the port handle binding inside the firmware. This could lead to queued work items for the fcport, if any, getting incorrect results. This patch fixes the issue by checking for device name changes after a call to get port database. Signed-off-by:

Rather than continuously allocating and freeing swl within the discovery process, simply pre-allocate it the first time that it's needed, cache it through the rest of the lifecycle of the driver and free it at module unload. Signed-off-by:
