Element phy_type is a bitmask and it only ever has 2 bits possibly set, and it is overkill to define as a u64, so redefine as a u32. This change resolves static code check complaint that "phy->phy_type &= ~PORT_TYPE_SAS;" would unintentionally clear the high 32 bits as well. Structure hisi_sas_phy is also reordered to ensure packing efficiency. Reported-by:

The symbolic name VLC_SA_RECEIVE_CREDENTIAL is not used anywhere in the kernel. Additionally, since SPC 5 the RECEIVE CREDENTIAL command is obsolete. The VLC_SA_RECEIVE_CREDENTIAL definition is misleading since it occurs outside the list of other variable length CDB service action codes (READ_32, WRITE_32, ...). Hence remove this definition.

Both aac_send_raw_srb() and aac_get_hba_info() may copy stack allocated structs to userspace without initializing all members of these structs. Clear out this memory to prevent information leaks.

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:

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:

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:
