For SD card reader devices that have the BLIST_IGN_MEDIA_CHANGE flag set, a MEDIUM MAY HAVE CHANGED unit attention is established after resuming from runtime suspend. Send a REQUEST SENSE to consume the UA. The "downside" is that for these devices we now rely on users to not change the medium (SD card) *during* a runtime suspend/resume cycle, i.e. when not unmounting. To enable runtime PM for an SD cardreader (device number 0:0:0:0), do: echo 0 > /sys/module/block/parameters/events_dfl_poll_msecs echo 1000 > /sys/bus/scsi/devices/0:0:0:0/power/autosuspend_delay_ms echo auto > /sys/bus/scsi/devices/0:0:0:0/power/control [mkp: use scsi_device flag instead of poking at BLIST] Link: https://lore.kernel.org/r/20210704075403.147114-3-martin.kepplinger@puri.smReviewed-by:

Add a new flag for devices that erroneously establish MEDIUM MAY HAVE CHANGED unit attentions. Drivers can set this flag to make the SCSI layer ignore media change events during resume.

libsas needs to include some header files in the scsi directory. However these are currently hardcoded with the path "../" in the C files. Do this in the Makefile to avoid hardcoding the path.

It is useful for testing purposes to be able to inject errors by writing bad protection information to media with checking disabled and then attempting to read it back.

The function used to dump sectors containing protection information errors was useful during initial development over a decade ago. However, dump_sector() substantially slows down the system during testing due to writing an entire sector's worth of data to syslog on every error. We now log plenty of information about the nature of detected protection information errors throughout the stack. Dumping the entire contents of an offending sector is no longer needed.

When a node moves to NPR state due to a device recovery event, the nlp_fc4_types in the node are cleared. An ADISC received for a node in the NPR state triggers an ADISC. Without fc4 types being known, the calls to register with the transport are no-op'd, thus no additional references are placed on the node by transport re-registrations. A subsequent RSCN could trigger another unregister request, which will decrement the reference counts, leading to the ref count hitting zero and the node being freed while futher discovery on the node is being attempted by the RSCN event handling. Fix by skipping the trigger of an ADISC when in NPR state. The normal ADISC process will kick off in the regular discovery path after receiving a response from name server.

During RSCN storms, some instances of LIP on SLI-3 adapters lead to a situation where FLOGIs keep failing with firmware indicating an illegal command error code. This situation was preceded by an ADISC completion that was processed while the link was down. This path on SLI-3 performs a CLEAR_LA and attempts to activate a VPI with REG_VPI. Later, as the FLOGI completes, it's no longer in sync with the VPI state. In SLI-3 it is illegal to have an active VPI during FLOGI. Resolve by circumventing the SLI-3 path that performs the CLEAR_LA and REG_VPI. The path will be taken after the FLOGI after the next Link Up.

In the PLOGI and ADISC completion handling, the device removal event could be skipped during some link errors. This could leave a stale node in UNUSED state. Driver unload would hang for a long time waiting for this node to be freed. Resolve by taking the following steps: - Always post ADISC completion events to discovery state machine upon ADISC completion. - In case of a completion error for PLOGI/ADISC, ensure that init refcount is dropped if not registered with transport.

On an RSCN event, the nodes specified in RSCN payload and in MAPPED state are moved to NPR state in order to revalidate the login. This triggers an immediate unregister from SCSI/NVMe backend. The assumption is that the node may be missing. The re-registration with the backend happens after either relogin (PLOGI/PRLI; if ADISC is disabled or login truly lost) or when ADISC completes successfully (rediscover with ADISC enabled). However, the NVMe-FC standard provides for an RSCN to be triggered when the remote port supports a discovery controller and there was a change of discovery log content. As the remote port typically also supports storage subsystems, this unregister causes all storage controller connections to fail and require reconnect. Correct by reworking the code to ensure that the unregistration only occurs when a login state is truly terminated, thereby leaving the NVMe storage controllers in place. The changes made are: - Retain node state in ADISC_ISSUE when scheduling ADISC ELS retry. - Do not clear wwpn/wwnn values upon ADISC failure. - Move MAPPED nodes to NPR during RSCN processing, but do not unregister with transport. On GIDFT completion, identify missing nodes (not marked NLP_NPR_2B_DISC) and unregister them. - Perform unregistration for nodes that will go through ADISC processing if ADISC completion fails. - Successful ADISC completion will move node back to MAPPED state.

If a LOGO is received for a node that is in the NPR state, post a DEVICE_RM event to allow clean up of the logged out node.
