| * scsi: lpfc: Fix crash when cpu count is 1 and null irq affinity maskJames Smart2019-08-071-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a configurations runs with a single cpu (such as a kdump kernel), which causes the driver to request a single vector, when the driver subsequently requests an irq affinity mask, the mask comes back null. The driver currently does nothing in this scenario, which leaves mappings to hardware queues incomplete and crashes the system. Fix by recognizing the null mask and assigning the vector to the first cpu in the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In qla2x00_alloc_fcport(), fcport is assigned to NULL in the error handling code on line 4880: fcport = NULL; Then fcport is used on lines 4883-4886: INIT_WORK(&fcport->del_work, qla24xx_delete_sess_fn); INIT_WORK(&fcport->reg_work, qla_register_fcport_fn); INIT_LIST_HEAD(&fcport->gnl_entry); INIT_LIST_HEAD(&fcport->list); Thus, possible null-pointer dereferences may occur. To fix these bugs, qla2x00_alloc_fcport() directly returns NULL in the error handling code. These bugs are found by a static analysis tool STCheck written by us.

| * scsi: mpt3sas: Use 63-bit DMA addressing on SAS35 HBASuganath Prabu2019-07-301-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as per hardware design, if DMA-able range contains all 64-bits set (0xFFFFFFFF-FFFFFFFF) then it results in a firmware fault. E.g. SGE's start address is 0xFFFFFFFF-FFFF000 and data length is 0x1000 bytes. when HBA tries to DMA the data at 0xFFFFFFFF-FFFFFFFF location then HBA will fault the firmware. Driver will set 63-bit DMA mask to ensure the above address will not be used.

| | | | | | | | | | | | | | | | | | | | Instead of using the generic 'fc_rport_priv' structure as argument and then having to painstakingly outcast this to fcoe_rport we should be passing the fcoe_rport structure itself and reduce complexity.

| | | | | | | | | | | | | | | | | | | | | | | | Gcc-9 complains for a memset across pointer boundaries, which happens as the code tries to allocate a flexible array on the stack. Turns out we cannot do this without relying on gcc-isms, so with this patch we'll embed the fc_rport_priv structure into fcoe_rport, can use the normal 'container_of' outcast, and will only have to do a memset over one structure.

| * | scsi: megaraid_sas: set an unlimited max_segment_sizeChristoph Hellwig2019-07-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using a virt_boundary_mask, as done for NVMe devices attached to megaraid_sas controllers, we require an unlimited max_segment_size as the virt boundary merging code assumes that. But we also need to propagate that to the DMA mapping layer to make dma-debug happy. The SCSI layer takes care of that when using the per-host virt_boundary setting, but given that megaraid_sas only wants to set the virt_boundary for actual NVMe devices, we can't rely on that. The DMA layer maximum segment is global to the HBA however, so we have to set it explicitly. This patch assumes that megaraid_sas does not have a segment size limitation, which seems true based on the SGL format, but will need to be verified.

This was fine before the introduction of CONFIG_GCC_PLUGIN_STRUCTLEAK_VERBOSE because each instance could occupy the same stack slot. However, now they each get their own copy, which leads to a huge increase in stack usage as seen from the compiler warning: drivers/scsi/lpfc/lpfc_debugfs.c: In function 'lpfc_debug_dump_all_queues': drivers/scsi/lpfc/lpfc_debugfs.c:6474:1: error: the frame size of 1712 bytes is larger than 100 bytes [-Werror=frame-larger-than=] Avoid this by not marking lpfc_debug_dump_qe() as inline so the compiler can choose to emit a static version of this function when it's needed or otherwise silently drop it. As an added benefit, not inlining multiple copies of this function means we save several kilobytes of .text section, reducing the file size from 47kb to 43. It is somewhat unusual to have a function that is static but not inline in a header file, but this does not cause problems here because it is only used by other inline functions. It would however seem reasonable to move all the lpfc_debug_dump_* functions into lpfc_debugfs.c and not mark them inline as a later cleanup.
