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.

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. Link: https://lore.kernel.org/r/20220911221505.117655-6-jsmart2021@gmail.comCo-developed-by:

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. Link: https://lore.kernel.org/r/20220911221505.117655-5-jsmart2021@gmail.comCo-developed-by:

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.

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.

In resetting the controller, SATA devices may be lost. The issue is that when we insert the bcast events to rescan the topology in hisi_sas_rescan_topology(), when we subsequently nexus reset the SATA devices in hisi_sas_async_I_T_nexus_reset(), there is a small timing window in which the remote phy is down and we process the bcast event (meaning that libsas judges that the disk is lost). Ensure that all bcast events are processed prior to the nexus reset to close this window. Link: https://lore.kernel.org/r/1662378529-101489-4-git-send-email-john.garry@huawei.comSigned-off-by:

Mike Christie authored
If a driver returns: - DID_TARGET_FAILURE - DID_NEXUS_FAILURE - DID_ALLOC_FAILURE - DID_MEDIUM_ERROR we hit a couple bugs: 1. The SCSI error handler runs because scsi_decide_disposition() has no case statements for them and we return FAILED. 2. For SG IO the userspace app gets a success status instead of failed, because scsi_result_to_blk_status() clears those errors. This patch adds a new internal error code byte for use by the SCSI midlayer. This will be used instead of the above error codes, so we don't have to play that clearing the host code game in scsi_result_to_blk_status() and drivers cannot accidentally use them. A subsequent commit will then remove the internal users of the above codes and convert us to use the new ones.

DID_ALLOC_FAILURE is internal to the SCSI layer. Drivers must not use it because: 1. It's not propagated upwards, so SG IO/passthrough users will not see an error and think a command was successful. 2. There is no handling for it in scsi_decide_disposition() so it results in entering SCSI error handling. By the code comment, it looks like the driver wanted a retryable error code, so this has it use DID_ERROR.
