FC-LS-5 specifies that a received RDF implies a possible change to fabric supported diagnostic functions. Endpoints are to re-perform the RDF exchange with the fabric to enable possible new features or adapt to changes in values. This patch adds the logic to RDF receive to re-perform the RDF exchange with the switch. Link: https://lore.kernel.org/r/20210514195559.119853-11-jsmart2021@gmail.comCo-developed-by:

Default behavior for the driver, when aborting an I/O, is to terminate the I/O with the adapter. The adapter will initiate an ABTS to terminate the exchange on the link and mark the exchange is terminated so that no further use of the sgl or any traffic for the exchange is worked on. Completion on the Abort is then posted to the driver, which as the I/O is terminated can complete the I/O to the OS. This completion may occur prior to the ABTS handshake completing on the wire. The ABTS handshake can take a long time to complete with timeouts and retries reaching 60+ seconds. Note: if retries fail, LOGO occurs. Some devices want to ensure that the ABTS handshake fully completes (this device has fully ack'd it) before the I/O completion is posted back to the OS, where a failed I/O may be retried via a different path. To support this behavior, an option was added to the driver to change I/O completion from the Abort cmd completion to the Exchange termination (aka ABTS) completion.

The driver is encountering a crash in lpfc_free_iocb_list() while performing initial attachment. Code review found this to be an errant failure path that was taken, jumping to a tag that then referenced structures that were uninitialized. Fix the failure path.

When a link bounce happens, there is a possibility that responses to requests posted prior to the link bounce could be received. This is problematic as the counter to track reglogin completion after link up can become out of sync with the real state. As there is no reason to process a request made in a prior link up context, eliminate all the disturbance by tagging the request with the event_tag maintained by the SLI Port for the link. The event_tag will change on every link state transition. As long as the tag matches the current event_tag, the response can be processed. If it doesn't match, just discard the response.

During link bounce testing, RPI counts were seen to differ from the number of nodes. For fabric and domain controllers, a temporary RPI is assigned, but the code isn't registering it. If the nodes do go away, such as on link down, the temporary RPI isn't being released. Change the way these two fabric services are managed, make them behave like any other remote port. Register the RPI and register with the transport. Never leave the nodes in a NPR or UNUSED state where their RPI is in limbo. This allows them to follow normal dev_loss_tmo handling, RPI refcounting, and normal removal rules. It also allows fabric I/Os to use the RPI for traffic requests. Note: There is some logic that still has a couple of exceptions when the Domain controller (0xfffcXX). There are cases where the fabric won't have a valid login but will send RDP. Other times, it will it send a LOGO then an RDP. It makes for ad-hoc behavior to manage the node. Exceptions are documented in the code.

When lpfc is handling a solicited and unsolicited PLOGI with another initiator, the remote initiator is never recovered. The node for the initiator is erroneouosly removed and all resources released. In lpfc_cmpl_els_plogi(), when lpfc_els_retry() returns a failure code, the driver is calling the state machine with a device remove event because the remote port is not currently registered with the SCSI or NVMe transports. The issue is that on a PLOGI "collision" the driver correctly aborts the solicited PLOGI and allows the unsolicited PLOGI to complete the process, but this process is interrupted with a device_rm event. Introduce logic in the PLOGI completion to capture the PLOGI collision event and jump out of the routine. This will avoid removal of the node. If there is no collision, the normal node removal will occur.

An 'unexpected timeout' message may be seen in a point-2-point topology. The message occurs when a PLOGI is received before the driver is notified of FLOGI completion. The FLOGI completion failure causes discovery to be triggered for a second time. The discovery timer is restarted but no new discovery activity is initiated, thus the timeout message eventually appears. In point-2-point, when discovery has progressed before the FLOGI completion is processed, it is not a failure. Add code to FLOGI completion to detect that discovery has progressed and exit the FLOGI handling (noop'ing it).

While testing NPIV and watching logins and used RPI levels, it was seen the used RPI count was much higher than the number of remote ports discovered. Code inspection showed that remote port removals on any NPIV instance are releasing the RPI, but not performing an UNREG_RPI with the adapter thus the reference counting never fully drops and the RPI is never fully released. This was happening on NPIV nodes due to a log of fabric ELS's to fabric addresses. This lack of UNREG_RPI was introduced by a prior node rework patch that performed the UNREG_RPI as part of node cleanup. To resolve the issue, do the following: - Restore the RPI release code, but move the location to so that it is in line with the new node cleanup design. - NPIV ports now release the RPI and drop the node when the caller sets the NLP_RELEASE_RPI flag. - Set the NLP_RELEASE_RPI flag in node cleanup which will trigger a release of RPI to free pool. - Ensure there's an UNREG_RPI at LOGO completion so that RPI release is completed. - Stop offline_prep from skipping nodes that are UNUSED. The RPI may not have been released. - Stop the default RPI handling in lpfc_cmpl_els_rsp() for SLI4. - Fixed up debugfs RPI displays for better debugging.

If an RTPG fails, we can't infer anything wrt. the state of the ports in the port group except that we were unable to reach the one port on which the RTPG had failed. "offline" is just a secondary port state, which means that we can't infer the state of any port in the PG from the failure (in fact, even the failed port might still be in "active/optimized" primary port access state). Therefore, when we encounter an RTPG failure, we should retry the RTPG on a different port. This avoids falsely setting port states to offline for unreachable ports. To do this, ports on which an RTPG has failed are temporarily set to "disabled" to avoid repeating the failed I/O on the same target port. Once the RTPG has either succeeded on one port or failed on all ports of the PG, the ports are enabled again. Link: https://lore.kernel.org/r/20210514153214.5626-1-mwilck@suse.comSigned-off-by:

The controller expects all data it sends/receives to be little-endian. Therefore, the packet struct definitions should use the __le16/32/64 types. Once those are correct, sparse reports several issues with the driver code, which are fixed here as well. The main issue observed was at the call to scsi_set_resid(), where the byteswapped parameter would eventually trigger the alignment check at drivers/scsi/sd.c:2009. At that point, the kernel would continuously complain about an "Unaligned partial completion", and no further I/O could occur. This gets the controller working on big endian powerpc64.

Currently, all command packet structs used by this driver are packed. However, only one (TW_SG_Entry) actually needs to be packed, because it uses 64-bit addresses at 32-bit alignment. To improve the quality of generated code, stop packing all of the other command packet structs. This requires adjusting the type of one misaligned "reserved" member. After this change, pahole reports that only one type had its layout change: the tw_compat_info member of TW_Device_Extension is now naturally aligned.
