A change in remote port removal introduced a spurious put which can cause a premature structure teardown. The affects were most notable when the driver attempted to unload as a null pointer would be hit. Fix by removing the unnecessary put. Signed-off-by:

On link down, transport is calling driver to abort outstanding ios. Driver erroneously rejects the abort if the port indicates it isn't logged in - which will be the case after the link down. Thus, the io can't clean up. This prevents reconnection at the transport level. Fix by allowing abort to proceed. Signed-off-by:

virtio_scsi tries to do exception handling after the default 30 seconds timeout expires. However, it's better to let the host control the timeout, otherwise with a heavy I/O load it is likely that an abort will also timeout. This leads to fatal errors like filesystems going offline. Disable the 'sd' timeout and allow the host to do exception handling, following the precedent of the storvsc driver. Hannes has a proposal to introduce timeouts in virtio, but this provides an immediate solution for stable kernels too. [mkp: fixed typo] Reported-by:

There's no need to use the static UTS_RELEASE string, since utsname()->release contains the same. This avoids rebuilding this file for every change of the release string. Signed-off-by:

FC disks issue I/O directly to the host storage port driver, this is diffirent to VHD disks where I/O is virtualized and timeout is handled by the host VSP (Virtualization Service Provider). FC disks are usually setup in a multipath system, and they don't want to reset timer on I/O timeout. Timeout is detected by multipath as a good time to failover and recover. Signed-off-by:

When running nvme detach-ns /dev/nvme0n1 -n 1 command, the nvmet lpfc driver crashes with this stack dump: kernel BUG at /root/NVME/lpfc_8.4/lpfc_sli.c:1393! invalid opcode: 0000 [#1] SMP Workqueue: nvmet-fc-cpu0 nvmet_fc_do_work_on_cpu [nvmet_fc] lpfc_sli4_issue_wqe+0x357/0x440 [lpfc] lpfc_nvmet_xmt_fcp_abort+0x36b/0x5c0 [lpfc] nvmet_fc_abort_op+0x30/0x50 [nvmet_fc] nvmet_fc_do_work_on_cpu+0xd9/0x130 [nvmet_fc] process_one_work+0x14e/0x410 worker_thread+0x116/0x490 kthread+0xc7/0xe0 ret_from_fork+0x3f/0x70 Crash is due to an uninitialized iocbq->vport pointer. Explicitly set the iocbq->vport field to phba->pport in lpfc_nvmet_sol_fcp_issue_abort as it does all abort iocbq initialization in the routine. Using phba->pport is ok because target does not support NPIV instances. Signed-off-by:

During every reset, IOCBs are allocated. So, at one point, number of allocated IOCBs reaches maximum limit and lpfc_sli_next_iotag fails. Allocate IOCBs only during initialization. Reuse them after every reset instead of allocating new set of IOCBs. Signed-off-by:

OS crashes after the completion of firmware download. Failure in posting SCSI SGL buffers because number of SGL buffers is less than total count. Some of the pending IOs are not completed by driver. SGL buffers for these IOs are not added back to the list. Pending IOs are not completed because lpfc_wq_list list is initialized before completion of pending IOs. Postpone lpfc_wq_list reinitialization by moving lpfc_sli4_queue_destroy() after lpfc_hba_down_post(). Signed-off-by:

In a server with an 8G adapter and a 32G adapter, running NVME and FCP, the server would crash with the following stack.

It's not supposed to have one. NVME is not supported on the 8G adapter, so the NVME PRLI, which started this flow shouldn't have been sent in the first place. Correct discovery engine to recognize when on an SLI3 rport, which doesn't support SLI3, if the rport supports only NVME, don't send a NVME PRLI. Instead, as no FC4 will be used, a LOGO is sent. If rport is FCP and NVME, only execute the SCSI PRLI. Signed-off-by:

Add skeleton driver for v3 hw in hisi_sas_v3_hw.c File hisi_sas_v3_hw.c will serve 2 purposes: - probing and initialisation of the controller based on pci device - hw layer for v3-based controllers The controller design is quite similar to v2 hw in hip07. However key differences include: -All v2 hw bugs are fixed (hopefully), so workarounds are not required -support for device deregistration -some interrupt modifications -configurable max device support Signed-off-by:
