The qdio layer currently provides its own infrastructure to scan for Request Queue completions & to report them to the device driver. This comes with several drawbacks - having an async tasklet & timer construct in qdio introduces additional lifetime complexity, and makes it harder to integrate them with the rest of the device driver. The timeouts are also currently hard-coded, and can't be tweaked without affecting other qdio drivers (ie. qeth). But due to recent enhancements to the qdio layer, zfcp can actually take full control of the Request Queue completion processing. It merely needs to opt-out from the qdio layer mechanisms by setting the scan_threshold to 0, and then use qdio_inspect_queue() to scan for completions. So re-implement the tasklet & timer mechanism in zfcp, while initially copying the scan conditions from qdio's handle_outbound() and qdio_outbound_tasklet(). One minor behavioural change is that zfcp_qdio_send() will unconditionally reduce the timeout to 1 HZ, rather than leaving it at 10 Hz if it was last armed by the tasklet. This just makes things more consistent. Also note that we can drop a lot of the accumulated cruft in qdio_outbound_tasklet(), as zfcp doesn't even use PCI interrupt requests any longer. This also slightly touches the Response Queue processing, as qdio_get_next_buffers() will no longer implicitly scan for Request Queue completions. So complete the migration to qdio_inspect_queue() here as well and make the tasklet_schedule() visible.

The error path from zfcp_adapter_enqueue() no longer attempts to remove the diagnostics attributes if they haven't been created yet. So remove the manual 'sysfs_established' guard for this case, and use device_add_groups() to add all adapter-related sysfs attributes in one go.

When zfcp_adapter_enqueue() fails to create the zfcp_sysfs_adapter_attrs group, it calls zfcp_adapter_unregister() to tear down the adapter state again. This then unconditionally attempts to remove the zfcp_sysfs_adapter_attrs group, resulting in a "group not found" WARN from sysfs code. Avoid this by copying most of zfcp_adapter_unregister() into the error path, allowing for more fine-granular roll-back. Then skip the sysfs tear-down steps if we haven't progressed this far in the initialization.

INIT_LIST_HEAD() is only needed for actual list heads, while req->list is used as a list entry. Note that when the error path in zfcp_fsf_req_send() removes the request from the adapter's list of pending requests, it actually looks up the request from the zfcp_reqlist - rather than just calling list_del(). So there's no risk of us calling list_del() on a request that hasn't been added to any list yet.

Commit a6dcfe08 ("scsi: qla2xxx: Limit interrupt vectors to number of CPUs") lowers the number of allocated MSI-X vectors to the number of CPUs. That breaks vector allocation assumptions in qla83xx_iospace_config(), qla24xx_enable_msix() and qla2x00_iospace_config(). Either of the functions computes maximum number of qpairs as: ha->max_qpairs = ha->msix_count - 1 (MB interrupt) - 1 (default response queue) - 1 (ATIO, in dual or pure target mode) max_qpairs is set to zero in case of two CPUs and initiator mode. The number is then used to allocate ha->queue_pair_map inside qla2x00_alloc_queues(). No allocation happens and ha->queue_pair_map is left NULL but the driver thinks there are queue pairs available. qla2xxx_queuecommand() tries to find a qpair in the map and crashes: if (ha->mqenable) { uint32_t tag; uint16_t hwq; struct qla_qpair *qpair = NULL; tag = blk_mq_unique_tag(cmd->request); hwq = blk_mq_unique_tag_to_hwq(tag); qpair = ha->queue_pair_map[hwq]; # <- HERE if (qpair) return qla2xxx_mqueuecommand(host, cmd, qpair); } BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [#1] SMP PTI CPU: 0 PID: 72 Comm: kworker/u4:3 Tainted: G W 5.10.0-rc1+ #25 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.0.0-prebuilt.qemu-project.org 04/01/2014 Workqueue: scsi_wq_7 fc_scsi_scan_rport [scsi_transport_fc] RIP: 0010:qla2xxx_queuecommand+0x16b/0x3f0 [qla2xxx] Call Trace: scsi_queue_rq+0x58c/0xa60 blk_mq_dispatch_rq_list+0x2b7/0x6f0 ? __sbitmap_get_word+0x2a/0x80 __blk_mq_sched_dispatch_requests+0xb8/0x170 blk_mq_sched_dispatch_requests+0x2b/0x50 __blk_mq_run_hw_queue+0x49/0xb0 __blk_mq_delay_run_hw_queue+0xfb/0x150 blk_mq_sched_insert_request+0xbe/0x110 blk_execute_rq+0x45/0x70 __scsi_execute+0x10e/0x250 scsi_probe_and_add_lun+0x228/0xda0 __scsi_scan_target+0xf4/0x620 ? __pm_runtime_resume+0x4f/0x70 scsi_scan_target+0x100/0x110 fc_scsi_scan_rport+0xa1/0xb0 [scsi_transport_fc] process_one_work+0x1ea/0x3b0 worker_thread+0x28/0x3b0 ? process_one_work+0x3b0/0x3b0 kthread+0x112/0x130 ? kthread_park+0x80/0x80 ret_from_fork+0x22/0x30 The driver should allocate enough vectors to provide every CPU it's own HW queue and still handle reserved (MB, RSP, ATIO) interrupts.

The variable rmd->blocks_per_row is used as a divisor and could be 0. Using rmd->blocks_per_row as a divisor without checking it for 0 first. Correct these possible divide by 0 conditions by insuring that rmd->blocks_per_row is not zero before usage. The check for non-0 was too late to prevent a divide by 0 condition.

This fixes an issue hitting the BUG_ON() in ibmvfc_do_work(). When going through a host action of IBMVFC_HOST_ACTION_RESET, we change the action to IBMVFC_HOST_ACTION_TGT_DEL, then drop the host lock, and reset the CRQ, which changes the host state to IBMVFC_NO_CRQ. If, prior to setting the host state to IBMVFC_NO_CRQ, ibmvfc_init_host() is called, it can then end up changing the host action to IBMVFC_HOST_ACTION_INIT. If we then change the host state to IBMVFC_NO_CRQ, we will then hit the BUG_ON(). Make a couple of changes to avoid this. Leave the host action to be IBMVFC_HOST_ACTION_RESET or IBMVFC_HOST_ACTION_REENABLE until after we drop the host lock and reset or reenable the CRQ. Also harden the host state machine to ensure we cannot leave the reset / reenable state until we've finished processing the reset or reenable.

The lpfc_hdw_queue attribute is to set the number of hardware queues to be created on the adapter. Normally, the value is set to a default, which allows the hw queue count to be sized dynamically based on adapter capabilities, CPU/platform architecture, or CPU type. Currently, when lpfc_hdw_queue is set to a specific value, is has no effect and the dynamic sizing occurs. The routine checking whether parameters are default or not ignores the lpfc_hdw_queue setting and invokes the dynamic logic. Fix the routine to additionally check the lpfc_hdw_queue attribute value before using dynamic scaling. Additionally, SLI-3 supports only a small number of queues with dedicated functions, thus it needs to be exempted from the variable scaling and set to the expected values.

In SLI-4, when performing a mailbox command with MBX_POLL, the driver uses the BMBX register to send the command rather than the MQ. A flag is set indicating the BMBX register is active and saves the mailbox job struct (mboxq) in the mbox_active element of the adapter. The routine then waits for completion or timeout. The mailbox job struct is not freed by the routine. In cases of timeout, the adapter will be reset. The lpfc_sli_mbox_sys_flush() routine will clean up the mbox in preparation for the reset. It clears the BMBX active flag and marks the job structure as MBX_NOT_FINISHED. But, it never frees the mboxq job structure. Expectation in both normal completion and timeout cases is that the issuer of the mbx command will free the structure. Unfortunately, not all calling paths are freeing the memory in cases of error. All calling paths were looked at and updated, if missing, to free the mboxq memory regardless of completion status.

During target port-swap testing with link flips, the initiator could encounter PRLI errors. If the target node disappears permanently, the ndlp is found stuck in UNUSED state with ref count of 1. The rmmod of the driver will hang waiting for this node to be freed. While handling a link error in PRLI completion path, the code intends to skip triggering the discovery state machine. However this is causing the final reference release path to be skipped. This causes the node to be stuck with ref count of 1 Fix by ensuring the code path triggers the device removal event on the node state machine.

Call traces are being seen that result from a nodelist structure ref counting error. They are typically seen after transmission of an LS_RJT ELS response. Aged code in lpfc_cmpl_els_rsp() calls lpfc_nlp_not_used() which, if the ndlp reference count is exactly 1, will decrement the reference count. Previously lpfc_nlp_put() was within lpfc_els_free_iocb(), and the 'put' within the free would only be invoked if cmdiocb->context1 was not NULL. Since the nodelist structure reference count is decremented when exiting lpfc_cmpl_els_rsp() the lpfc_nlp_not_used() calls are no longer required. Calling them is causing the reference count issue. Fix by removing the lpfc_nlp_not_used() calls. Link: https://lore.kernel.org/r/20210412013127.2387-4-jsmart2021@gmail.comCo-developed-by:

Fix a crash caused by a double put on the node when the driver completed an ACC for an unsolicted abort on the same node. The second put was executed by lpfc_nlp_not_used() and is wrong because the completion routine executes the nlp_put when the iocbq was released. Additionally, the driver is issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node into NPR. This call does nothing. Remove the lpfc_nlp_not_used call and additional set_state in the completion routine. Remove the lpfc_nlp_set_state post issue_logo. Isn't necessary.

Rmmod on SLI-4 adapters is sometimes hitting a bad ptr dereference in lpfc_els_free_iocb(). A prior patch refactored the lpfc_sli_abort_iocb() routine. One of the changes was to convert from building/sending an abort within the routine to using a common routine. The reworked routine passes, without modification, the pring ptr to the new common routine. The older routine had logic to check SLI-3 vs SLI-4 and adapt the pring ptr if necessary as callers were passing SLI-3 pointers even when not on an SLI-4 adapter. The new routine is missing this check and adapt, so the SLI-3 ring pointers are being used in SLI-4 paths. Fix by cleaning up the calling routines. In review, there is no need to pass the ring ptr argument to abort_iocb at all. The routine can look at the adapter type itself and reference the proper ring.
