After seeing some interoperability issues with ADISC, it was determined the ELS definitions in lpfc were using types that allowed the compiler to add pad to the structure, causing the structure to no longer be per spec. The offending structures are ADISC, FAN, and RNID. This patch implements the simple fix of eliminating the pad by forcing the compiler to pack the structure. Care was taken to ensure field accesses won't be by operations that would hit a bad field alignment. The better solution would be to convert to the uapi fc header definitions, but the number of changes required to do is rather intrusive so this course of action was deferred. Signed-off-by:

When connected to a high number of remote ports, the driver is encountering PLOGI errors. The errors are due to adapter detected failures indicating illegal field values. Turns out the driver was prematurely clearing an RPI bitmask before waiting for an UNREG_RPI mailbox completion. This allowed the RPI to be reused before it was actually available. Fix by clearing RPI bitmask only after UNREG_RPI mailbox completion. Signed-off-by:

scsi-mq operation inherently performs pre-allocation of resources for blk-mq request queues. Even though the kdump environment reduces the configuration to a single CPU, thus 1 hardware queue, which helps significantly, the resources are still rather large due to the per request allocations. blk-mq pre-allocations can be over 4KB per request. With adapter can_queue values in the 4k or 8k range, this can easily be 32MBs before any other driver memory is factored in. Driver SGL DMA buffer allocation can be up to 8KB per request as well adding an additional 64MB. Totals are well over 100MB for a single shost. Given kdump memory auto-sizing utilities don't accommodate this amount of memory well, it's very possible for kdump to fail due to lack of memory. Fix by having the driver recognize that it is booting within a kdump context and reduce the number of requests it will support to a more reasonable value. Signed-off-by:

Static structure ufs_hba_qcom_vops, of type ufs_hba_variant_ops, is used only once, when it is passed as the second argument to function ufshcd_pltfrm_init(). In the definition of ufshcd_pltfrm_init(), its second parameter (corresponding to ufs_hba_qcom_vops) is declared as constant. Hence declare ufs_hba_qcom_vops itself constant as well to protect it from unintended modification. Issue found with Coccinelle. Signed-off-by:

As spin_unlock_irq will enable interrupts. Function lpfc_findnode_rpi is called from lpfc_sli_abts_err_handler (./drivers/scsi/lpfc/lpfc_sli.c) <- lpfc_sli_async_event_handler <- lpfc_sli_process_unsol_iocb <- lpfc_sli_handle_fast_ring_event <- lpfc_sli_fp_intr_handler <- lpfc_sli_intr_handler and lpfc_sli_intr_handler is an interrupt handler. Interrupts are enabled in interrupt handler. Use spin_lock_irqsave/spin_unlock_irqrestore instead of spin_(un)lock_irq in IRQ context to avoid this.

Avoid code duplication between qla2x00_alloc_offload_mem() and qla2x00_alloc_fw_dump() by moving the FCE and EFT buffer allocation and initialization to separate functions. Cleanly track failure and success by making sure that the ha->eft, ha->fce and respective eft_dma, fce_dma members are set if and only if the buffers are properly allocated and initialized. Avoid pointless buffer reallocation. Eliminate some goto statements. Make sure the fce_enabled flag is cleared when the FCE buffer is freed.

When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make sure they can be included from user-space. Currently, scsi_bsg_fc.h, scsi_netlink.h, and scsi_netlink_fc.h are excluded from the test coverage. To make them join the compile-test, we need to fix the build errors attached below.

This patch provides a module parameter and sysfs interface to select whether the queue depth for each device should be based on the value suggested by firmware (the default) or the maximum supported by the controller (can_queue). Although we have a sysfs interface per sdev to change the queue depth of individual scsi devices, this implementation provides a single sysfs entry per shost to switch between the controller max and the value reported by firmware. The module parameter can provide an interface for one time grub settings and provides persistent settings across the boot. [mkp: tweaked commit desc] Signed-off-by:
