| * scsi: lpfc: Fix crash involving race between FLOGI timeout and devloss handlerJustin Tee2022-11-172-15/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a FLOGI completes with a sequence timeout error, a freed kref ptr dereference crash can occur due to a timing race involving ndlp referencing in lpfc_dev_loss_tmo_callbk. Fix by ensuring the driver accounts for an outstanding FLOGI when dev_loss is active. Also, don't remove the HBA_FLOGI_OUTSTANDING flag when the FLOGI is retried to allow the driver to handle the reference counts correctly in lpfc_dev_loss_tmo_handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dynamic mi_ver value holds the currently configured MI setting. mi_ver was being displayed as part of the cmf_info sysfs attribute, when the output string meant to display MI capabilities instead. Add a mi_cap member in the lpfc_pc_sli4_params structure that will store MI capabilities during initialization so that cmf_info prints out capabilities instead of current configuration.

| * scsi: lpfc: Correct bandwidth logging during receipt of congestion sync WCQEJustin Tee2022-11-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lpfc_cmf_timer adjusts phba->cmf_link_byte_count periodically and can artifically inflate bandwidth percent. During bandwidth calculation, correct for this by setting a cap of logging a maximum of 100%. Bandwidth calculation is only used for display under LOG_CGN_MGMT so there is no expectation of impacts on performance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adapter configurations with limited EQ resources may fail to initialize. Firmware resources are queried in lpfc_sli4_read_config(). The driver parameters cfg_irq_chann and cfg_hdw_queue are adjusted from defaults if constrained by firmware resources. The minimum resource check includes a special allocation for queues such as ELS, MBOX, NVME LS. However the additional reservation was also incorrectly applied to EQ resources. Reordered WQ|CQ|EQ resource checks to apply the special allocation adjustment to WQ and CQ resources only.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5e633302ace1 ("scsi: lpfc: vmid: Add support for VMID in mailbox command") introduced allocations for the VMID resources in lpfc_create_port() after the call to scsi_host_alloc(). Upon failure on the VMID allocations, the new code would branch to the 'out' label, which returns NULL without unwinding anything, thus skipping the call to scsi_host_put(). Fix the problem by creating a separate label 'out_free_vmid' to unwind the VMID resources and make the 'out_put_shost' label call only scsi_host_put(), as was done before the introduction of allocations for VMID.

| * scsi: lpfc: Rework FDMI attribute registration for unintential paddingJames Smart2022-09-162-669/+350
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During a stress offline/online test in PT2PT topology, target rediscovery can fail with a specific target vendor array. When the HBA transitions to online mode it is possible to receive an unsolicited FLOGI before processing the Link Up event. The received FLOGI will set the defer_flogi_acc_flag, which instructs the driver to wait until it transmits its own FLOGI before ACKing the received FLOGI. In this failure scenario, the link up processing clears the set defer_flogi_acc_flag before we have sent out the FLOGI. As the target has the higher WWPN and is responsible for sending the PLOGI, the target is stuck waiting for its FLOGI_ACC that the driver will never send. Remove the clear of defer_flogi_acc_flag from Link Up event processing. In this stress test case, the defer_flogi_acc_flag is cleared during the Link Down event processing anyways.
