The patch refactors the general ELS handling paths to migrate to SLI-4 structures or common element abstractions. The fabric login paths are revised as part of this patch: - New generic lpfc_sli_prep_els_req_rsp jump table routine - Introduce ls_rjt_error_be and ulp_bde64_le unions to correct legacy endianness assignments - 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. This replaces the set-as-SLI3 then translate to SLI4 behavior of the past. - Clean up poor indentation on some of the ELS paths Link: https://lore.kernel.org/r/20220225022308.16486-5-jsmart2021@gmail.comCo-developed-by: NJustin Tee <justin.tee@broadcom.com> Signed-off-by: NJustin Tee <justin.tee@broadcom.com> Signed-off-by: NJames Smart <jsmart2021@gmail.com> Signed-off-by: NMartin K.

Introduce lpfc_prep_wqe routine. The lpfc_prep_wqe() routine is used with lpfc_sli_issue_iocb() and lpfc_sli_issue_iocb_wait(). The routine performs additional SLI-4 wqe field setting that the generic routines did not perform as they kept their actions compatible with both SLI3 and SLI4.

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.comCo-developed-by: NJustin Tee <justin.tee@broadcom.com> Signed-off-by: NJustin Tee <justin.tee@broadcom.com> Signed-off-by: NJames Smart <jsmart2021@gmail.com> Signed-off-by: NMartin K.

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.

The soft_wwpn/soft_wwn functionality, which allows the driver to modify service parameters in an attempt to override the adapter-assigned WWN, was originally attempted to be removed roughly 6 yrs ago as new fabric features were being introduced that clashed with the implementation. In the end, the feature was left in with the user being responsible if things went south. We've reached a point where soft_wwn is no longer functional and is failing in almost all production use cases. Use of Fabric features such as Fabric Assigned WWPN and Automatic DPORT is now prevalent and the features require coordination between the adapter and driver that can't be solved by the simplistic update of the service parameters. As it is no longer functional, the feature is to be removed. There are still ways to override the adapter-assigned WWN but they require the admin to invoke bios/efi level menus.

The driver uses irq_set_affinity_hint to set the affinity for the lpfc interrupts to a mask corresponding to the local NUMA node to avoid performance overhead on AMD architectures. However, irq_set_affinity_hint() setting the affinity is an undocumented side effect that this function also sets the affinity under the hood. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Also, as per the commit dcaa2136 ("scsi: lpfc: Change default IRQ model on AMD architectures"): "On AMD architecture, revert the irq allocation to the normal style (non-managed) and then use irq_set_affinity_hint() to set the cpu affinity and disable user-space rebalancing." we don't really need to set the affinity_hint as user-space rebalancing for the lpfc interrupts is not desired. Hence, replace the irq_set_affinity_hint() with irq_set_affinity() which only applies the affinity for the interrupts.

The driver is calling schedule_timeout after the DA_ID nameserver request and LOGO commands are issued to the fabric by the initiator virtual endport. These fixed delay functions are causing long delays in the driver's worker thread when processing discovery I/Os in a serialized fashion, which is then triggering mailbox timeout errors artificially. To fix this, don't wait on the DA_ID request to complete and call wait_event_timeout to allow the vport delete thread to make progress on an event driven basis rather than fixing the wait time.

During heavy I/O testing with issue_lip to bounce the link, occasionally I/O is terminated with status 3 result 9, which means the RPI is suspended. The I/O is completed and this type of error will result in immediate retry by the SCSI layer. The retry count expires and the I/O fails and returns error to the application. To avoid these quick retry/retries exhausted scenarios change the return code given to the midlayer to DID_REQUEUE rather than DID_ERROR. This gets them retried, and eventually succeed when the link recovers.

During rmmod testing, messages appeared indicating lpfc_mbuf_pool entries were still busy. This situation was only seen doing rmmod after at least 1 vport (NPIV) instance was created and destroyed. The number of messages scaled with the number of vports created. When a vport is created, it can receive a PLOGI from another initiator Nport. When this happens, the driver prepares to ack the PLOGI and prepares an RPI for registration (via mbx cmd) which includes an mbuf allocation. During the unsolicited PLOGI processing and after the RPI preparation, the driver recognizes it is one of the vport instances and decides to reject the PLOGI. During the LS_RJT preparation for the PLOGI, the mailbox struct allocated for RPI registration is freed, but the mbuf that was also allocated is not released. Fix by freeing the mbuf with the mailbox struct in the LS_RJT path. As part of the code review to figure the issue out a couple of other areas where found that also would not have released the mbuf. Those are cleaned up as well.

A commit introduced formal regstration of all Fabric nodes to the SCSI transport as well as REG/UNREG RPI mailbox requests. The commit introduced the NLP_RELEASE_RPI flag for rports set in the lpfc_cmpl_els_logo_acc() routine to help clean up the RPIs. This new code caused the driver to release the RPI value used for the remote port and marked the RPI invalid. When the driver later attempted to re-login, it would use the invalid RPI and the adapter rejected the PLOGI request. As no login occurred, the devloss timer on the rport expired and connectivity was lost. This patch corrects the code by removing the snippet that requests the rpi to be unregistered. This change only occurs on a node that is already marked to be rediscovered. This puts the code back to its original behavior, preserving the already-assigned rpi value (registered or not) which can be used on the re-login attempts.

A link bounce to a slow fabric may observe FDISC response delays lasting longer than devloss tmo. Current logic decrements the final fabric node kref during a devloss tmo event. This results in a NULL ptr dereference crash if the FDISC completes for that fabric node after devloss tmo. Fix by adding the NLP_IN_RECOV_POST_DEV_LOSS flag, which is set when devloss tmo triggers and we've noticed that fabric node recovery has already started or finished in between the time lpfc_dev_loss_tmo_callbk queues lpfc_dev_loss_tmo_handler. If fabric node recovery succeeds, then the driver reverses the devloss tmo marked kref put with a kref get. If fabric node recovery fails, then the final kref put relies on the ELS timing out or the REG_LOGIN cmpl routine.

If an FC link down transition while PLOGIs are outstanding to fabric well known addresses, outstanding ABTS requests may result in a NULL pointer dereference. Driver unload requests may hang with repeated "2878" log messages. The Link down processing results in ABTS requests for outstanding ELS requests. The Abort WQEs are sent for the ELSs before the driver had set the link state to down. Thus the driver is sending the Abort with the expectation that an ABTS will be sent on the wire. The Abort request is stalled waiting for the link to come up. In some conditions the driver may auto-complete the ELSs thus if the link does come up, the Abort completions may reference an invalid structure. Fix by ensuring that Abort set the flag to avoid link traffic if issued due to conditions where the link failed.

A remote nport can stop responding to PLOGI beyond the ELS I/O timeout under some fault conditions. When this happens, the non-response triggers a dev_loss_tmo event from the transport which causes the driver to abort the PLOGI and stop any retries. This was due to a policy in the ELS completion handler whenever an ELS was terminated due to driver request. Revise the ELS completion path to detect PLOGIs that were aborted and allow retries.

An error is detected with the following report when unloading the driver: "KASAN: use-after-free in lpfc_unreg_rpi+0x1b1b" The NLP_REG_LOGIN_SEND nlp_flag is set in lpfc_reg_fab_ctrl_node(), but the flag is not cleared upon completion of the login. This allows a second call to lpfc_unreg_rpi() to proceed with nlp_rpi set to LPFC_RPI_ALLOW_ERROR. This results in a use after free access when used as an rpi_ids array index. Fix by clearing the NLP_REG_LOGIN_SEND nlp_flag in lpfc_mbx_cmpl_fc_reg_login().

Applications determine loop support in part by querying the 'pls' sysfs node. Reporting of 'pls' (Private Loop Support) is derived from the descriptor returned by the COMMON_GET_SLI4_PARAMETERS mailbox command, which is issued during initialization or after a reset. The value of this field may change if there is a dynamic SFP change. The driver currently will not pick up the change as there was no reset scenario. Rework to commonize the sending of the COMMON_GET_SLI4_PARAMETERS command. Add the calling of the routine after receipt of an async event indicating an SFP change.

A prior patch introduced HBA_NEEDS_CFG_PORT flag logic, but in lpfc_sli_brdrestart_s3() code path, right after HBA_NEEDS_CFG_PORT is set, the phba->hba_flag is cleared in lpfc_sli_brdreset(). Fix by calling lpfc_sli_chipset_init() to wait for successful restart of the HBA in lpfc_host_reset_handler() after lpfc_sli_brdrestart(). lpfc_sli_chipset_init() sets the HBA_NEEDS_CFG_PORT flag so that the lpfc_sli_hba_setup() routine from lpfc_online() will execute lpfc_sli_config_port() initialization step when the brdrestart is successful.

In cases when lpfc_enable_pci_dev() fails, lpfc_printf_log() with LOG_TRACE_EVENT set will call lpfc_dmp_dbg() which uses the phba->port_list_lock. However, phba->port_list_lock does not get initialized until lpfc_setup_driver_resource_phase1(). Thus, any initialization routine with LOG_TRACE_EVENT log message prior to lpfc_setup_driver_resource_phase1() will crash. Revert LOG_TRACE_EVENT back to LOG_INIT for all log messages in routines prior to lpfc_setup_driver_resource_phase1().

Except for the features passed to blk_queue_required_elevator_features, elevator.h is only needed internally to the block layer. Move the ELEVATOR_F_* definitions to blkdev.h, and the move elevator.h to block/, dropping all the spurious includes outside of that.
