2022-03-29scsi: ufs: qcom: Drop custom Android boot parametersKrzysztof Kozlowski
The QCOM UFS driver requires an androidboot.bootdevice command line argument matching the UFS device name. If the name is different, it refuses to probe. This androidboot.bootdevice is provided by stock/vendor (from an Android-based device) bootloader. This does not make sense from Linux point of view. Driver should be able to boot regardless of bootloader. Driver should not depend on some Android custom environment data.

2022-03-29scsi: core: Fix sbitmap depth in scsi_realloc_sdev_budget_map()John Garry
In commit edb854a3680b ("scsi: core: Reallocate device's budget map on queue depth change"), the sbitmap for the device budget map may be reallocated after the slave device depth is configured. When the sbitmap is reallocated we use the result from scsi_device_max_queue_depth() for the sbitmap size, but don't resize to match the actual device queue depth. Fix by resizing the sbitmap after reallocating the budget sbitmap. We do this instead of init'ing the sbitmap to the device queue depth as the user may want to change the queue depth later via sysfs or other.

2022-03-29scsi: ibmvscsis: Increase INITIAL_SRP_LIMIT to 1024Tyrel Datwyler
The adapter request_limit is hardcoded to be INITIAL_SRP_LIMIT which is currently an arbitrary value of 800. Increase this value to 1024 which better matches the characteristics of the typical IBMi Initiator that supports 32 LUNs and a queue depth of 32. This change also has the secondary benefit of being a power of two as required by the kfifo API. Since, Commit ab9bb6318b09 ("Partially revert "kfifo: fix kfifo_alloc() and kfifo_init()"") the size of IU pool for each target has been rounded down to 512 when attempting to kfifo_init() those pools with the current request_limit size of 800.

2022-03-29scsi: pmcraid: Remove the PMCRAID_PASSTHROUGH_IOCTL ioctl implementationChristophe JAILLET
The whole passthrough ioctl path looks completely broken. For example it DMA maps the scatterlist and after that copies data to it, which is prohibited by the DMA API contract. Moreover, in pmcraid_alloc_sglist(), the pointer returned by a sgl_alloc_order() call is not recorded anywhere which is pointless. So remove the PMCRAID_PASSTHROUGH_IOCTL ioctl implementation entirely. Should it be needed, we should reimplement it using the proper block layer request mapping helpers.

2022-03-29scsi: lpfc: Fix queue failures when recovering from PCI parity errorJames Smart
When recovering from a pci-parity error the driver is failing to re-create queues, causing recovery to fail. Looking deeper, it was found that the interrupt vector count allocated on the recovery was fewer than the vectors originally allocated. This disparity resulted in CPU map entries with stale information. When the driver tries to re-create the queues, it attempts to use the stale information which indicates an eq/interrupt vector that was no longer created. Fix by clearng the cpup map array before enabling and requesting the IRQs in the lpfc_sli_reset_slot_s4 routine().

2022-03-29scsi: lpfc: Fix unload hang after back to back PCI EEH faultsJames Smart
When injecting EEH errors the port is getting hung up waiting on the node list to empty, message number 0233. The driver is stuck at this point and also can't unload. The driver makes transport remoteport delete calls which try to abort I/O's, but the EEH daemon has already called the driver to detach and the detachment has set the global FC_UNLOADING flag. There are several code paths that will avoid I/O cleanup if the FC_UNLOADING flag is set, resulting in transports waiting for I/O while the driver is waiting on transports to clean up. Additionally, during study of the list, a locking issue was found in lpfc_sli_abort_iocb_ring that could corrupt the list. A special case was added to the lpfc_cleanup() routine to call lpfc_sli_flush_rings() if the driver is FC_UNLOADING and if the pci-slot is offline (e.g. EEH). The SLI4 part of lpfc_sli_abort_iocb_ring() is changed to use the ring_lock. Also added code to cancel the I/Os if the pci-slot is offline and added checks and returns for the FC_UNLOADING and HBA_IOQ_FLUSH flags to prevent trying to send an I/O that we cannot handle.

2022-03-29scsi: lpfc: Improve PCI EEH Error and Recovery HandlingJames Smart
Following EEH errors, the driver can crash or hang when deleting the localport or when attempting to unload. The EEH handlers in the driver did not notify the NVMe-FC transport before tearing the driver down. This was delayed until the resume steps. This worked for SCSI because lpfc_block_scsi() would notify the scsi_fc_transport that the target was not available but it would not clean up all the references to the ndlp. The SLI3 prep for dev reset handler did the lpfc_offline_prep() and lpfc_offline() calls to get the port stopped before restarting. The SLI4 version of the prep for dev reset just destroyed the queues and did not stop NVMe from continuing. Also because the port was not really stopped the localport destroy would hang because the transport was still waiting for I/O. Additionally, a devloss tmo can fire and post events to a stopped worker thread creating another hang condition. lpfc_sli4_prep_dev_for_reset() is modified to call lpfc_offline_prep() and lpfc_offline() rather than just lpfc_scsi_dev_block() to ensure both SCSI and NVMe transports are notified to block I/O to the driver. Logic is added to devloss handler and worker thread to clean up ndlp references and quiesce appropriately.

This patch refactors the BSG paths to use SLI-4 as the primary interface. - Conversion away from using SLI-3 iocb structures to set/access fields in common routines. Use the new generic get/set routines that were added. This move changes code from indirect structure references to using local variables with the generic routines. - Refactor routines when setting non-generic fields, to have both SLI3 and SLI4 specific sections.

Convert the SLI4 fast and slow paths to use native SLI4 wqe constructs instead of iocb SLI3-isms. Includes the following: - Create simple get_xxx and set_xxx routines to wrapper access to common elements in both SLI3 and SLI4 commands - allowing calling routines to avoid sli-rev-specific structures to access the elements. - using the wqe in the job structure as the primary element - use defines from SLI-4, not SLI-3 - Removal of iocb to wqe conversion from fast and slow path - Add below routines to handle fast path lpfc_prep_embed_io - prepares the wqe for fast path lpfc_wqe_bpl2sgl - manages bpl to sgl conversion lpfc_sli_wqe2iocb - converts a WQE to IOCB for SLI-3 path - Add lpfc_sli3_iocb2wcqecmpl in completion path to convert an SLI-3 iocb completion to wcqe completion - Refactor some of the code that works on both revs for clarity Link: https://lore.kernel.org/r/20220225022308.16486-3-jsmart2021@gmail.com Co-developed-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: Justin Tee <justin.tee@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

2022-03-15scsi: lpfc: SLI path split: Refactor lpfc_iocbqJames Smart
Currently, SLI3 and SLI4 data paths use the same lpfc_iocbq structure. This is a "common" structure but many of the components refer to sli-rev specific entities which can lead the developer astray as to what they actually mean, should be set to, or when they should be used. This first patch prepares the lpfc_iocbq structure so that elements common to both SLI3 and SLI4 data paths are more appropriately named, making it clear they apply generically. Fieldnames based on 'iocb' (sli3) or 'wqe' (sli4) which are actually generic to the paths are renamed to 'cmd': - iocb_flag is renamed to cmd_flag - lpfc_vmid_iocb_tag is renamed to lpfc_vmid_tag - fabric_iocb_cmpl is renamed to fabric_cmd_cmpl - wait_iocb_cmpl is renamed to wait_cmd_cmpl - iocb_cmpl and wqe_cmpl are combined and renamed to cmd_cmpl - rsvd2 member is renamed to num_bdes due to pre-existing usage The structure name itself will retain the iocb reference as changing to a more relevant "job" or "cmd" title induces many hundreds of line changes for only a name change. lpfc_post_buffer is also renamed to lpfc_sli3_post_buffer to indicate use in the SLI3 path only.
