2022-09-16crypto: hisilicon/qm - get hardware features from hardware registersWeili Qian5-69/+170
Before hardware V3, hardwares do not provide the feature registers, driver resolves hardware differences based on the hardware version. As a result, the driver does not support the new hardware. Hardware V3 and later versions support to obtain hardware features, such as power-gating management and doorbell isolation, through the hardware registers. To be compatible with later hardware versions, the features of the current device is obtained by reading the hardware registers instead of the hardware version.

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.

2022-09-15scsi: lpfc: Move scsi_host_template outside dynamically allocated/freed phbaJames Smart4-34/+48
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.

2022-09-15scsi: lpfc: Fix multiple NVMe remoteport registration calls for the same NPort IDJames Smart3-40/+36
When a target makes the mistake of registering a FC4 type with the fabric, but then rejects a PRLI of that type, the lpfc driver incorrectly retries the PRLI causing multiple registrations with the transport. The driver needs to detect the reject reason data and stop any retry. Rework the PRLI reject scenarios.

2022-09-15scsi: lpfc: Add missing free iocb and nlp kref put for early return VMID casesJames Smart1-3/+7
Sometimes VMID targets are not getting rediscovered after a port reset. The iocb is not freed in lpfc_cmpl_ct_cmd_vmid(), which is the completion function for the appid CT commands. So after a port reset, the count of sges is less than the expected count of 250. This causes post reset operation logic to fail and keep the port offline. Fix by freeing the iocb and kref put for the lpfc_cmpl_ct_cmd_vmid() early return cases.

2022-09-15scsi: lpfc: Fix mbuf pool resource detected as busy at driver unloadJames Smart1-0/+7
In a situation where the node state changes while a REG_LOGIN is in progress, the LPFC_MBOXQ_t structure is cleared and reused for an UNREG_LOGIN command to release RPI resources without first freeing the mbuf pool resource allocated for REG_LOGIN. Release mbuf pool resource prior to repurposing of the mailbox command structure from REG_LOGIN to UNREG_LOGIN.

2022-09-15scsi: lpfc: Fix FLOGI ACC with wrong SID in PT2PT topologyJames Smart1-2/+7
When a FLOGI is received before we have issued our FLOGI, the ACC response to the received FLOGI is issued with SID 2 instead of the expected fabric controller SID. Certain target vendors ignore the malformed ACC with SID 2 and wait for a properly filled ACC with a fabric controller SID. 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. Fix by adding a check for the defer_flogi_acc flag to know whether or not to clear the FC_PT2PT flag on link up.

2022-09-15scsi: lpfc: Fix prli_fc4_req checks in PRLI handlingJames Smart1-2/+2
The if statment check (prli_fc4_req & PRLI_NVME_TYPE) evaluates to true when receiving a PRLI request for bogus FC4 type codes that happen to have the 3rd or 5th bit set because PRLI_NVME_TYPE is 0x28. This leads to sending a PRLI_NVME_ACC even for bogus FC4 type codes. Change the bitwise & check to an exact == type code check to ensure we send PRLI_NVME_ACC only for NVME type coded PRLI requests.

ahd_linux_setup_iocell_info() intentionally writes to the const-marked aic79xx_iocell_info array, but is called during __init, so the location is actually writable at this point on most architectures. Annotate this explicitly with __ro_after_init to avoid static analysis confusion.
