Implement graceful handling of surprise or orderly removal of PCIe HBA: - Detect a hot removal of the controller at certain critical places in the driver. Early detection will help to reduce the time taken for cleaning up the hot-removed controller at the driver level. - Poll the status of the port enable issued after reset once every 5 seconds to avoid a long delay in detecting unavailable controller.

Switch to the new generic PCI power management framework. Also, remove unnecessary calls to the PCI helper functions (such as pci_set_power_state(), pci_enable_wake(), pci_save_state(), pci_restore_state() etc).

The historical commit 5e018f7e ("Remove PC9800 support") from 2004 in linux's history.git removed the config WD33C93_PIO to tweak the scsi wd33c93 driver for the PC9800. Some dead code in drivers/scsi/wd33c93.[ch] under an ifdef WD33C93_PIO continued to remain in the repository until now. Remove this dead code.

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct fw_control_info.

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in struct hpt_iop_request_scsi_command and refactor the rest of the code, accordingly. The following pieces of code suggest that the one element of array sg_list in struct hpt_iop_request_scsi_command is not taken into account when calculating the total size for both struct hpt_iop_request_scsi_command and the maximum number of elements sg_list will contain: 1047 req->header.size = cpu_to_le32( 1048 sizeof(struct hpt_iop_request_scsi_command) 1049 - sizeof(struct hpt_iopsg) 1050 + sg_count * sizeof(struct hpt_iopsg)); 1400 req_size = sizeof(struct hpt_iop_request_scsi_command) 1401 + sizeof(struct hpt_iopsg) * (hba->max_sg_descriptors - 1); So it's safe to replace the one-element array with a flexible-array member and update the code above, accordingly: now we don't need to subtract sizeof(struct hpt_iopsg) from sizeof(struct hpt_iop_request_scsi_command) because this is implicitly done by the flex-array transformation.

This is caused by missing accounting for running_req for when an internal abort command completes. In commit 2cbbf489 ("scsi: pm8001: Use libsas internal abort support") we started to send internal abort commands as a proper sas_task. In this when we deliver a sas_task to HW the per-device running_req is incremented in pm8001_queue_command(). However it is never decremented for internal abort commnds, so decrement in pm8001_mpi_task_abort_resp().

When executing SMP task failed, the smp_execute_task_sg() calls del_timer() to delete "slow_task->timer". However, if the timer handler sas_task_internal_timedout() is running, the del_timer() in smp_execute_task_sg() will not stop it and a UAF will happen. The process is shown below: (thread 1) | (thread 2) smp_execute_task_sg() | sas_task_internal_timedout() ... | del_timer() | ... | ... sas_free_task(task) | kfree(task->slow_task) //FREE| | task->slow_task->... //USE Fix by calling del_timer_sync() in smp_execute_task_sg(), which makes sure the timer handler have finished before the "task->slow_task" is deallocated.

In order to help the compiler reason about the destination buffer in struct fc_nl_event, add a flexible array member for this purpose. However, since the header is UAPI, it must not change size or layout, so a union is used. The allocation size calculations are also corrected (it was potentially allocating an extra 8 bytes), and the padding is zeroed to avoid leaking kernel heap memory contents.

SCSI_MOD is a helper config symbol for configuring RAID_ATTRS properly, i.e., RAID_ATTRS needs to be m when SCSI=m. This helper config symbol SCSI_MOD still shows up even in kernel configurations that do not select the block subsystem and where SCSI is not even a configuration option mentioned and selectable. Make this SCSI_MOD depend on BLOCK, so that it only shows up when it is slightly relevant in the kernel configuration.

Removed the lpfc_fdmi_attr_entry and lpfc_fdmi_attr_def structures that had a union causing unintentional zero padding, which required the usage of __packed. They are replaced with explicit lpfc_fdmi_attr_u32, lpfc_fdmi_attr_wwn, lpfc_fdmi_attr_fc4types, and lpfc_fdmi_attr_string structure defines instead of living in a union. This rids of ambiguous compiler zero padding, and entailed cleaning up bitwise endian declarations. As such, all FDMI attribute registration routines are replaced with generic void *arg and handlers for each of the newly defined attribute structure types.

On a PCI hotplug capable system, it is possible for scsi_device_put() to happen after lpfc_pci_remove_one() is called. As a result, the sdev->host->hostt->module dereference is for a previously freed memory location because the phba structure containing the hostt template was already freed when lpfc_pci_remove_one() returned. Since the lpfc module is still loaded during power slot disable, all scsi_host_templates should be declared as part of the global data segment instead of inside the heap allocated phba structure. This way the sdev->host->hostt memory area is always valid as long as the module is loaded regardless if PCI hotplug dynamically allocates or frees phba structures. Move all scsi_host_templates in the phba structure to global variables. Create a small helper routine to determine appropriate sg_tablesize during shost allocation.

When a target makes the mistake of registering a FC4 type with the fabric, but then rejects a PRLI of that type, the lpfc driver incorrectly retries the PRLI causing multiple registrations with the transport.

Sometimes VMID targets are not getting rediscovered after a port reset. The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the completion function for the appid CT commands. So after a port reset, the count of sges is less than the expected count of 250. This causes post reset operation logic to fail and keep the port offline. Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid() early return cases. Link: https://lore.kernel.org/r/20220911221505.117655-5-jsmart2021@gmail.comCo-developed-by:

When a FLOGI is received before we have issued our FLOGI, the ACC response to the received FLOGI is issued with SID 2 instead of the expected fabric controller SID. Certain target vendors ignore the malformed ACC with SID 2 and wait for a properly filled ACC with a fabric controller SID. The lpfc_sli_prep_wqe() routine depends on the FC_PT2PT flag to fill in the fabric controller SID when in PT2PT mode, but due to a previous commit the flag was getting cleared. Fix by adding a check for the defer_flogi_acc flag to know whether or not to clear the FC_PT2PT flag on link up.

The if statment check (prli_fc4_req & PRLI_NVME_TYPE) evaluates to true when receiving a PRLI request for bogus FC4 type codes that happen to have the 3rd or 5th bit set because PRLI_NVME_TYPE is 0x28. This leads to sending a PRLI_NVME_ACC even for bogus FC4 type codes. Change the bitwise & check to an exact == type code check to ensure we send PRLI_NVME_ACC only for NVME type coded PRLI requests.

There are three error paths which return success: 1) Propagate the error code from mpi3mr_post_transport_req() if it fails. 2) Return -EINVAL if "ioc_status != MPI3_IOCSTATUS_SUCCESS". 3) Return -EINVAL if "le16_to_cpu(mpi_reply.response_data_length) != sizeof(struct rep_manu_reply)" Link: https://lore.kernel.org/r/YyMIJh1HU2Qz9+Rs@kili Fixes: 2bd37e28 ("scsi: mpi3mr: Add framework to issue MPT transport cmds") Acked-by:

ahd_linux_setup_iocell_info() intentionally writes to the const-marked aic79xx_iocell_info array, but is called during __init, so the location is actually writable at this point on most architectures. Annotate this explicitly with __ro_after_init to avoid static analysis confusion.
