TLS requires a strict pdu pacing via MSG_EOR to signal the end of a record and subsequent encryption. If we do not set MSG_EOR at the end of a sequence the record won't be closed, encryption doesn't start, and we end up with a send stall as the message will never be passed on to the TCP layer. So do not check for the queue status when TLS is enabled but rather make the MSG_MORE setting dependent on the current request only.

If the user disabled a nvmet namespace, it is removed from the subsystem namespaces list. When nvmet processes a command directed to an nsid that was disabled, it cannot differentiate between a nsid that is disabled vs. a non-existent namespace, and resorts to return NVME_SC_INVALID_NS with the dnr bit set. This translates to a non-retryable status for the host, which translates to a user error. We should expect disabled namespaces to not cause an I/O error in a multipath environment. Address this by searching a configfs item for the namespace nvmet failed to find, and if we found one, conclude that the namespace is disabled (perhaps temporarily). Return NVME_SC_INTERNAL_PATH_ERROR in this case and keep DNR bit cleared.

When we teardown the controller, we wait for pending I/Os to complete (sq->ref on all queues to drop to zero) and then we go over the commands, and free their command buffers in case they are still fetching data from the host (e.g. processing nvme writes) and have yet to take a reference on the sq. However, we may miss the case where commands have failed before executing and are queued for sending a response, but will never occur because the queue socket is already down. In this case we may miss deallocating command buffers. Solve this by freeing all commands buffers as nvmet_tcp_free_cmd_buffers is idempotent anyways.

While I/O is running, if the pci bus error occurs then in-flight I/O can not complete. Worst, if at this time, user (logically) hot-unplug the nvme disk then the nvme_remove() code path can't forward progress until in-flight I/O is cancelled. So these sequence of events may potentially hang hot-unplug code path indefinitely. This patch helps cancel the pending/in-flight I/O from the nvme request timeout handler in case the nvme controller is in the terminal (DEAD/DELETING/DELETING_NOIO) state and that helps nvme_remove() code path forward progress and finish successfully.

On system where native nvme multipath is configured and iopolicy is set to numa but the nvme controller numa node id is undefined or -1 (NUMA_NO_NODE) then avoid calculating node distance for finding optimal io path. In such case we may access numa distance table with invalid index and that may potentially refer to incorrect memory. So this patch ensures that if the nvme controller numa node id is -1 then instead of calculating node distance for finding optimal io path, we set the numa node distance of such controller to default 10 (LOCAL_DISTANCE).

Linux 6.9 made the nvme multipath nodes not properly pick up changes when the LBA size goes smaller after an nvme format. This is because we now try to inherit the queue settings for the multipath node entirely from the individual paths. That is the right thing to do for I/O size limitations, which make up most of the queue limits, but it is wrong for changes to the namespace configuration, where we do want to pick up the new format, which will eventually show up on all paths once they are re-queried. Fix this by not inheriting the block size and related fields and always for updating them.

When KCSAN and CONSTRUCTORS are enabled, one can trigger the "Unpatched return thunk in use. This should not happen!" catch-all warning. Usually, when objtool runs on the .o objects, it does generate a section .return_sites which contains all offsets in the objects to the return thunks of the functions present there. Those return thunks then get patched at runtime by the alternatives.

The -Woverride-init warn about code that may be intentional or not, but the inintentional ones tend to be real bugs, so there is a bit of disagreement on whether this warning option should be enabled by default and we have multiple settings in scripts/Makefile.extrawarn as well as individual subsystems. Older versions of clang only supported -Wno-initializer-overrides with the same meaning as gcc's -Woverride-init, though all supported versions now work with both. Because of this difference, an earlier cleanup of mine accidentally turned the clang warning off for W=1 builds and only left it on for W=2, while it's still enabled for gcc with W=1. There is also one driver that only turns the warning off for newer versions of gcc but not other compilers, and some but not all the Makefiles still use a cc-disable-warning conditional that is no longer needed with supported compilers here. Address all of the above by removing the special cases for clang and always turning the warning off unconditionally where it got in the way, using the syntax that is supported by both compilers.

Pull SCSI fixes and updates from James Bottomley: "Fully half this pull is updates to lpfc and qla2xxx which got committed just as the merge window opened. A sizeable fraction of the driver updates are simple bug fixes (and lock reworks for bug fixes in the case of lpfc), so rather than splitting the few actual enhancements out, we're just adding the drivers to the -rc1 pull. The enhancements for lpfc are log message removals, copyright updates and three patches redefining types. For qla2xxx it's just removing a debug message on module removal and the manufacturer detail update. The two major fixes are the sg teardown race and a core error leg problem with the procfs directory not being removed if we destroy a created host that never got to the running state. The rest are minor fixes and constifications" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (41 commits) scsi: bnx2fc: Remove spin_lock_bh while releasing resources after upload scsi: core: Fix unremoved procfs host directory regression scsi: mpi3mr: Avoid memcpy field-spanning write WARNING scsi: sd: Fix TCG OPAL unlock on system resume scsi: sg: Avoid sg device teardown race scsi: lpfc: Copyright updates for 14.4.0.1 patches scsi: lpfc: Update lpfc version to 14.4.0.1 scsi: lpfc: Define types in a union for generic void *context3 ptr scsi: lpfc: Define lpfc_dmabuf type for ctx_buf ptr scsi: lpfc: Define lpfc_nodelist type for ctx_ndlp ptr scsi: lpfc: Use a dedicated lock for ras_fwlog state scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up() scsi: lpfc: Replace hbalock with ndlp lock in lpfc_nvme_unregister_port() scsi: lpfc: Update lpfc_ramp_down_queue_handler() logic scsi: lpfc: Remove IRQF_ONESHOT flag from threaded IRQ handling scsi: lpfc: Move NPIV's transport unregistration to after resource clean up scsi: lpfc: Remove unnecessary log message in queuecommand path scsi: qla2xxx: Update version to 10.02.09.200-k scsi: qla2xxx: Delay I/O Abort on PCI error scsi: qla2xxx: Change debug message during driver unload ...
