[PATCH v2] xhci: Allow RPM on the USB controller (1022:43f7) by default

by Basavaraj Natikar

The AMD USB host controller (1022:43f7) does not enter PCI D3 by default when nothing is connected. This is due to the policy introduced by 'commit a611bf473d1f ("xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devices")', which only covers 1.2 or later devices. Therefore, by default, allow RPM on the AMD USB controller [1022:43f7].

[PATCH v2 2/2] of: overlay: Synchronize of_overlay_remove() with the devlink removals

by Herve Codina

In the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are destroyed and devlinks are removed. During the step 2, OF nodes are destroyed but __of_changeset_entry_destroy() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 ... Indeed, during the devlink removals performed at step 1, the removal itself releasing the device (and the attached of_node) is done by a job queued in a workqueue and so, it is done asynchronously with respect to function calls. When the warning is present, of_node_put() will be called but wrongly too late from the workqueue job. In order to be sure that any ongoing devlink removals are done before the of_node destruction, synchronize the of_overlay_remove() with the devlink removals.

[PATCH v2] USB:UAS:return ENODEV when submit urbs fail with device not attached.

by Weitao Wang

In the scenario of entering hibernation with udisk in the system, if the udisk was gone or resume fail in the thaw phase of hibernation. Its state will be set to NOTATTACHED. At this point, usb_hub_wq was already freezed and can't not handle disconnect event. Next, in the poweroff phase of hibernation, SYNCHRONIZE_CACHE SCSI command will be sent to this udisk when poweroff this scsi device, which will cause uas_submit_urbs to be called to submit URB for sense/data/cmd pipe. However, these URBs will submit fail as device was set to NOTATTACHED state. Then, uas_submit_urbs will return a value SCSI_MLQUEUE_DEVICE_BUSY to the caller. That will lead the SCSI layer go into an ugly loop and system fail to go into hibernation. On the other hand, when we specially check for -ENODEV in function uas_queuecommand_lck, returning DID_ERROR to SCSI layer will cause device poweroff fail and system shutdown instead of entering hibernation. To fix this issue, let uas_submit_urbs function to return a value -ENODEV when submit URB fail with device in NOTATTACHED state. At the same time, we need to translate -ENODEV to DID_NOT_CONNECT for the SCSI layer.

[PATCH 6.1.y 0/6] Delay VERW - 6.1.y backport

by Pawan Gupta

This is the backport of recently upstreamed series that moves VERW execution to a later point in exit-to-user path. This is needed because in some cases it may be possible for data accessed after VERW executions may end into MDS affected CPU buffers. Moving VERW closer to ring transition reduces the attack surface. Patch 1/6 includes a minor fix that is queued for upstream: https://lore.kernel.org/lkml/170899674562.398.6398007479766564897.tip-bot2@… Patch 1,2,5 and 6 needed conflict resolution. I saw a few new warnings: arch/x86/entry/entry.o: warning: objtool: mds_verw_sel+0x0: unreachable instruction I tried using REACHABLE, but that did not fix the warning. For the below warning: vmlinux.o: warning: objtool: .altinstr_replacement+0x17: unsupported relocation in alternatives section not sure if this is related to this series or a pre-existing warning, I will check later without this series. I am not too concerned because the alternative did substitute verw correctly: entry_SYSCALL_64: ... 0xffffffff8200013d <+253>: swapgs 0xffffffff82000140 <+256>: verw 0xffffffff82000000 0xffffffff82000148 <+264>: sysretq 0xffffffff8200014b <+267>: int3 --- Pawan Gupta (5): x86/bugs: Add asm helpers for executing VERW x86/entry_64: Add VERW just before userspace transition x86/entry_32: Add VERW just before userspace transition x86/bugs: Use ALTERNATIVE() instead of mds_user_clear static key KVM/VMX: Move VERW closer to VMentry for MDS mitigation Sean Christopherson (1): KVM/VMX: Use BT+JNC, i.e. EFLAGS.CF to select VMRESUME vs. VMLAUNCH Documentation/x86/mds.rst | 38 +++++++++++++++++++++++++----------- arch/x86/entry/entry.S | 22 +++++++++++++++++++++ arch/x86/entry/entry_32.S | 3 +++ arch/x86/entry/entry_64.S | 11 +++++++++++ arch/x86/entry/entry_64_compat.S | 1 + arch/x86/include/asm/cpufeatures.h | 2 +- arch/x86/include/asm/entry-common.h | 1 - arch/x86/include/asm/nospec-branch.h | 25 ++++++++++++------------ arch/x86/kernel/cpu/bugs.c | 15 ++++++-------- arch/x86/kernel/nmi.c | 3 --- arch/x86/kvm/vmx/run_flags.h | 7 +++++-- arch/x86/kvm/vmx/vmenter.S | 9 ++++++--- arch/x86/kvm/vmx/vmx.c | 12 ++++++++---- 13 files changed, 103 insertions(+), 46 deletions(-) --- base-commit: 81e1dc2f70014b9523dd02ca763788e4f81e5bac change-id: 20240226-delay-verw-backport-6-1-y-4b0cec84087c

[PATCH v2 1/2] driver core: Introduce device_link_wait_removal()

by Herve Codina

The commit 80dd33cf72d1 ("drivers: base: Fix device link removal") introduces a workqueue to release the consumer and supplier devices used in the devlink. In the job queued, devices are release and in turn, when all the references to these devices are dropped, the release function of the device itself is called. Nothing is present to provide some synchronisation with this workqueue in order to ensure that all ongoing releasing operations are done and so, some other operations can be started safely. For instance, in the following sequence: 1) of_platform_depopulate() 2) of_overlay_remove() During the step 1, devices are released and related devlinks are removed (jobs pushed in the workqueue). During the step 2, OF nodes are destroyed but, without any synchronisation with devlink removal jobs, of_overlay_remove() can raise warnings related to missing of_node_put(): ERROR: memory leak, expected refcount 1 instead of 2 Indeed, the missing of_node_put() call is going to be done, too late, from the workqueue job execution. Introduce device_link_wait_removal() to offer a way to synchronize operations waiting for the end of devlink removals (i.e. end of workqueue jobs). Also, as a flushing operation is done on the workqueue, the workqueue used is moved from a system-wide workqueue to a local one.
