commit d5dcc336 upstream. The TRB_SMM flag indicates that DMA has completed the TD service with this TRB. Usually it’s a last TRB in TD. In case of ISOC transfer for bInterval > 1 each ISOC transfer contains more than one TD associated with usb request (one TD per ITP). In such case the TRB_SMM flag will be set in every TD and driver will recognize the end of transfer after processing the first TD with TRB_SMM. In result driver stops updating request->actual and returns incorrect actual length. To fix this issue driver additionally must check TRB_CHAIN which is not used for isochronous transfers.

commit b46a6b09 upstream. ISO OUT endpoint is enabled during queuing first usb request in transfer ring and disabled when TRBERR is reported by controller. After TRBERR and before next transfer added to TR driver must again reenable endpoint but does not. To solve this issue during processing TRBERR event driver must set the flag EP_UPDATE_EP_TRBADDR in priv_ep->flags field.

commit f9b995b4 upstream. Since 1599069a ("phy: core: Warn when phy_power_on is called before phy_init") the driver complains. In my case (Amlogic SoC) the warning is: phy phy-fe03e000.phy.2: phy_power_on was called before phy_init So change the order of the two calls.

commit 1b1b672c upstream. This adds the necessary ACPI ID for Intel Meteor Lake IOM devices. The callback function is_memory() is modified so that it also checks if the resource descriptor passed to it is a memory type "Address Space Resource Descriptor". On Intel Meteor Lake the ACPI memory resource is not described using the "32-bit Memory Range Descriptor" because the memory is outside of the 32-bit address space. The memory resource is described using the "Address Space Resource Descriptor" instead. Intel Meteor Lake is the first platform to describe the memory resource for this device with Address Space Resource Descriptor, but it most likely will not be the last. Therefore the change to the is_memory() callback function is made generic. Signed-off-by:

commit c1e5c2f0 upstream. Fix incorrect pin assignment values when connecting to a monitor with Type-C receptacle instead of a plug. According to specification, an UFP_D receptacle's pin assignment should came from the UFP_D pin assignments field (bit 23:16), while an UFP_D plug's assignments are described in the DFP_D pin assignments (bit 15:8) during Mode Discovery. For example the LG 27 UL850-W is a monitor with Type-C receptacle. The monitor responds to MODE DISCOVERY command with following DisplayPort Capability flag: dp->alt->vdo=0x140045 The existing logic only take cares of UPF_D plug case, and would take the bit 15:8 for this 0x140045 case. This results in an non-existing pin assignment 0x0 in dp_altmode_configure. To fix this problem a new set of macros are introduced to take plug/receptacle differences into consideration.

commit 5f73aa2c upstream. The recent commit 87d0e2f4 ("usb: typec: ucsi: add a common function ucsi_unregister_connectors()") introduced a regression that caused NULL dereference at reading the power supply sysfs. It's a stale sysfs entry that should have been removed but remains with NULL ops. The commit changed the error handling to skip the entries after a NULL con->wq, and this leaves the power device unreleased. For addressing the regression, the straight revert is applied here. Further code improvements can be done from the scratch again.

Fix the dwc3_core_exit() (e.g. called during suspend) and open-coded dwc3_probe() error-path sequences that got this wrong.

commit 33e32158 upstream. After xHC controller is started, either in probe or resume, it can take a while before any of the connected usb devices are visible to the roothub due to link training. It's possible xhci driver loads, sees no acivity and suspends the host before the USB device is visible. In one testcase with a hotplugged xHC controller the host finally detected the connected USB device and generated a wake 500ms after host initial start. If hosts didn't suspend the device duringe training it probablty wouldn't take up to 500ms to detect it, but looking at specs reveal USB3 link training has a couple long timeout values, such as 120ms RxDetectQuietTimeout, and 360ms PollingLFPSTimeout. So Add a 500ms grace period that keeps polling the roothub for 500ms after start, preventing runtime suspend until USB devices are detected. Cc: stable@vger.kernel.org Signed-off-by:

commit fe8f65b0 upstream. Xen blkfront advertises its support of the persistent grants feature when it first setting up and when resuming in 'talk_to_blkback()'. Then, blkback reads the advertised value when it connects with blkfront and decides if it will use the persistent grants feature or not, and advertises its decision to blkfront. Blkfront reads the blkback's decision and it also makes the decision for the use of the feature. Commit 402c43ea ("xen-blkfront: Apply 'feature_persistent' parameter when connect"), however, made the blkfront's read of the parameter for disabling the advertisement, namely 'feature_persistent', to be done when it negotiate, not when advertise. Therefore blkfront advertises without reading the parameter. As the field for caching the parameter value is zero-initialized, it always advertises as the feature is disabled, so that the persistent grants feature becomes always disabled. This commit fixes the issue by making the blkfront does parmeter caching just before the advertisement.

commit 9f5e0fe5 upstream. The advertisement of the persistent grants feature (writing 'feature-persistent' to xenbus) should mean not the decision for using the feature but only the availability of the feature. However, commit 74a85247 ("xen-blkfront: add a parameter for disabling of persistent grants") made a field of blkfront, which was a place for saving only the negotiation result, to be used for yet another purpose: caching of the 'feature_persistent' parameter value. As a result, the advertisement, which should follow only the parameter value, becomes inconsistent. This commit fixes the misuse of the semantic by making blkfront saves the parameter value in a separate place and advertises the support based on only the saved value.

[ Upstream commit 8782fb61 ] The mmap lock protects the page walker from changes to the page tables during the walk. However a read lock is insufficient to protect those areas which don't have a VMA as munmap() detaches the VMAs before downgrading to a read lock and actually tearing down PTEs/page tables. For users of walk_page_range() the solution is to simply call pte_hole() immediately without checking the actual page tables when a VMA is not present. We now never call __walk_page_range() without a valid vma. For walk_page_range_novma() the locking requirements are tightened to require the mmap write lock to be taken, and then walking the pgd directly with 'no_vma' set. This in turn means that all page walkers either have a valid vma, or it's that special 'novma' case for page table debugging. As a result, all the odd '(!walk->vma && !walk->no_vma)' tests can be removed. Fixes: dd2283f2 ("mm: mmap: zap pages with read mmap_sem in munmap") Reported-by:

[ Upstream commit 0204750b ] KVM should not claim to virtualize unknown IA32_ARCH_CAPABILITIES bits. When kvm_get_arch_capabilities() was originally written, there were only a few bits defined in this MSR, and KVM could virtualize all of them. However, over the years, several bits have been defined that KVM cannot just blindly pass through to the guest without additional work (such as virtualizing an MSR promised by the IA32_ARCH_CAPABILITES feature bit). Define a mask of supported IA32_ARCH_CAPABILITIES bits, and mask off any other bits that are set in the hardware MSR.

[ Upstream commit ee0175b3 ] By using 16-bit I/O on the GPIO peripheral, which is apparently not safe on MIPS, the IMR can end up containing garbage. This then results in interrupt triggers for lines that don't have an interrupt handler associated. The irq_desc lookup fails, and the ISR will not be cleared, keeping the CPU busy until reboot, or until another IMR operation restores the correct value. This situation appears to happen very rarely, for < 0.5% of IMR writes. Instead of using 8-bit or 16-bit I/O operations on the 32-bit memory mapped peripheral registers, switch to using 32-bit I/O only, operating on the entire bank for all single bit line settings. For 2-bit line settings, with 16-bit port values, stick to manual (un)packing. This issue has been seen on RTL8382M (HPE 1920-16G), RTL8391M (Netgear GS728TP v2), and RTL8393M (D-Link DGS-1210-52 F3, Zyxel GS1900-48).

[ Upstream commit f233d2be ] The driver does not check if the cooling state passed to gpio_fan_set_cur_state() exceeds the maximum cooling state as stored in fan_data->num_speeds. Since the cooling state is later used as an array index in set_fan_speed(), an array out of bounds access can occur. This can be exploited by setting the state of the thermal cooling device to arbitrary values, causing for example a kernel oops when unavailable memory is accessed this way.

[ Upstream commit 35f73cca ] The function raspberrypi_fw_get_rate (e.g. used for the recalc_rate hook) can fail to get the clock rate from the firmware. In this case we cannot return a signed error value, which would be casted to unsigned long. Fix this by returning 0 instead. Signed-off-by:

[ Upstream commit 9b1ac046 ] Commit 4c08d4bb ("powerpc/papr_scm: Add perf interface support") added performance monitoring support for papr-scm nvdimm devices via perf interface. Commit also added an array in papr_scm_priv structure called "nvdimm_events_map", which got filled based on the result of H_SCM_PERFORMANCE_STATS hcall. Currently there is an assumption that the order of events in the stats buffer, returned by the hypervisor is same. And order also happens to matches with the events specified in nvdimm driver code. But this assumption is not documented in Power Architecture Platform Requirements (PAPR) document. Although the order of events happens to be same on current generation od system, but it might not be true in future generation systems. Fix the issue, by adding a static mapping for nvdimm events to corresponding stat-id, and removing the dynamic map from papr_scm_priv structure. Also remove the function papr_scm_pmu_check_events from papr_scm.c file, as we no longer need to copy stat-ids dynamically.

[ Upstream commit 4b592061 ] In the original commit 9a34b453 ("clk: Add support for runtime PM"), the commit message mentioned that pm_runtime_put_sync() would be done at the end of clk_core_unprepare(). This mirrors the operations in clk_core_prepare() in the opposite order. However, the actual code that was added wasn't in the order the commit message described. Move clk_pm_runtime_put() to the end of clk_core_unprepare() so that it is in the correct order. Fixes: 9a34b453 ("clk: Add support for runtime PM") Signed-off-by:

[ Upstream commit 35b0fac8 ] In the previous commits that added CLK_OPS_PARENT_ENABLE, support for this flag was only added to rate change operations (rate setting and reparent) and disabling unused subtree. It was not added to the clock gate related operations. Any hardware driver that needs it for these operations will either see bogus results, or worse, hang. This has been seen on MT8192 and MT8195, where the imp_ii2_* clk drivers set this, but dumping debugfs clk_summary would cause it to hang.
