2025-05-09drm/fdinfo: Protect against driver unbindTvrtko Ursulin
commit 5b1834d6202f86180e451ad1a2a8a193a1da18fc upstream. If we unbind a driver from the PCI device with an active DRM client, subsequent read of the fdinfo data associated with the file descriptor in question will not end well. Protect the path with a drm_dev_enter/exit() pair.

2025-05-09cpufreq: intel_pstate: Unchecked MSR aceess in legacy modeSrinivas Pandruvada
commit ac4e04d9e378f5aa826c2406ad7871ae1b6a6fb9 upstream. When turbo mode is unavailable on a Skylake-X system, executing the command: # echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo results in an unchecked MSR access error: WRMSR to 0x199 (attempted to write 0x0000000100001300). This issue was reproduced on an OEM (Original Equipment Manufacturer) system and is not a common problem across all Skylake-X systems. This error occurs because the MSR 0x199 Turbo Engage Bit (bit 32) is set when turbo mode is disabled. The issue arises when intel_pstate fails to detect that turbo mode is disabled. Here intel_pstate relies on MSR_IA32_MISC_ENABLE bit 38 to determine the status of turbo mode. However, on this system, bit 38 is not set even when turbo mode is disabled. According to the Intel Software Developer's Manual (SDM), the BIOS sets this bit during platform initialization to enable or disable opportunistic processor performance operations. Logically, this bit should be set in such cases. However, the SDM also specifies that "OS and applications must use CPUID leaf 06H to detect processors with opportunistic processor performance operations enabled." Therefore, in addition to checking MSR_IA32_MISC_ENABLE bit 38, verify that CPUID.06H:EAX[1] is 0 to accurately determine if turbo mode is disabled.

2025-05-09Revert "rndis_host: Flag RNDIS modems as WWAN devices"Christian Heusel
commit 765f253e28909f161b0211f85cf0431cfee7d6df upstream. This reverts commit 67d1a8956d2d62fe6b4c13ebabb57806098511d8. Since this commit has been proven to be problematic for the setup of USB-tethered ethernet connections and the related breakage is very noticeable for users it should be reverted until a fixed version of the change can be rolled out.

2025-05-02usb: xhci: Fix Short Packet handling rework ignoring errorsMichal Pecio
commit 9e3a28793d2fde7a709e814d2504652eaba6ae98 upstream. A Short Packet event before the last TRB of a TD is followed by another event on the final TRB on spec-compliant HCs, which is most of them. A 'last_td_was_short' flag was added to know if a TD has just completed as Short Packet and another event is to come. The flag was cleared after seeing the event (unless no TDs are pending, but that's a separate bug) or seeing a new TD complete as something other than Short Packet. A rework replaced the flag with an 'old_trb_comp_code' variable. When an event doesn't match the pending TD and the previous event was Short Packet, the new event is silently ignored. To preserve old behavior, 'old_trb_comp_code' should be cleared at this point, but instead it is being set to current comp code, which is often Short Packet again. This can cause more events to be silently ignored, even though they are no longer connected with the old TD that completed short and indicate a serious problem with the driver or the xHC. Common device classes like UAC in async mode, UVC, serial or the UAS status pipe complete as Short Packet routinely and could be affected. Clear 'old_trb_comp_code' to zero, which is an invalid completion code and the same value the variable starts with. This restores original behavior on Short Packet and also works for illegal Etron events, which the code has been extended to cover too.

2025-05-02iommu: Handle race with default domain setupRobin Murphy
commit b46064a18810bad3aea089a79993ca5ea7a3d2b2 upstream. It turns out that deferred default domain creation leaves a subtle race window during iommu_device_register() wherein a client driver may asynchronously probe in parallel and get as far as performing DMA API operations with dma-direct, only to be switched to iommu-dma underfoot once the default domain attachment finally happens, with obviously disastrous consequences. Even the wonky of_iommu_configure() path is at risk, since iommu_fwspec_init() will no longer defer client probe as the instance ops are (necessarily) already registered, and the "replay" iommu_probe_device() call can see dev->iommu_group already set and so think there's nothing to do either. Fortunately we already have the right tool in the right place in the form of iommu_device_use_default_domain(), which just needs to ensure that said default domain is actually ready to *be* used. Deferring the client probe shouldn't have too much impact, given that this only happens while the IOMMU driver is probing, and thus due to kick the deferred probe list again once it finishes.

2025-05-02vmxnet3: Fix malformed packet sizing in vmxnet3_process_xdpDaniel Borkmann
commit 4c2227656d9003f4d77afc76f34dd81b95e4c2c4 upstream. vmxnet3 driver's XDP handling is buggy for packet sizes using ring0 (that is, packet sizes between 128 - 3k bytes). We noticed MTU-related connectivity issues with Cilium's service load- balancing in case of vmxnet3 as NIC underneath. A simple curl to a HTTP backend service where the XDP LB was doing IPIP encap led to overly large packet sizes but only for *some* of the packets (e.g. HTTP GET request) while others (e.g. the prior TCP 3WHS) looked completely fine on the wire. In fact, the pcap recording on the backend node actually revealed that the node with the XDP LB was leaking uninitialized kernel data onto the wire for the affected packets, for example, while the packets should have been 152 bytes their actual size was 1482 bytes, so the remainder after 152 bytes was padded with whatever other data was in that page at the time (e.g. we saw user/payload data from prior processed packets). We only noticed this through an MTU issue, e.g. when the XDP LB node and the backend node both had the same MTU (e.g. 1500) then the curl request got dropped on the backend node's NIC given the packet was too large even though the IPIP-encapped packet normally would never even come close to the MTU limit. Lowering the MTU on the XDP LB (e.g. 1480) allowed to let the curl request succeed (which also indicates that the kernel ignored the padding, and thus the issue wasn't very user-visible). Commit e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") was too eager to also switch xdp_prepare_buff() from rcd->len to rbi->len. It really needs to stick to rcd->len which is the actual packet length from the descriptor. The latter we also feed into vmxnet3_process_xdp_small(), by the way, and it indicates the correct length needed to initialize the xdp->{data,data_end} parts. For e127ce7699c1 ("vmxnet3: Fix missing reserved tailroom") the relevant part was adapting xdp_init_buff() to address the warning given the xdp_data_hard_end() depends on xdp->frame_sz. With that fixed, traffic on the wire looks good again.

In the field we observed that, for example, probing a bad micro-SD cards in an external USB card reader (or maybe cards were good but cables were flaky) sometimes takes longer than 2 minutes due to multiple retries at various levels of the stack. We can not block uevent_show() method for that long because udev is reading that attribute very often and that blocks udev and interferes with booting of the system. The change that introduced locking was concerned with dev_uevent() racing with unbinding the driver. However we can handle it without locking (which will be done in subsequent patch). There was also claim that synchronization with probe() is needed to properly load USB drivers, however this is a red herring: the change adding the lock was introduced in May of last year and USB loading and probing worked properly for many years before that.

2025-05-02iommu: Clear iommu-dma ops on cleanupRobin Murphy
[ Upstream commit 280e5a30100578106a4305ce0118e0aa9b866f12 ] If iommu_device_register() encounters an error, it can end up tearing down already-configured groups and default domains, however this currently still leaves devices hooked up to iommu-dma (and even historically the behaviour in this area was at best inconsistent across architectures/drivers...) Although in the case that an IOMMU is present whose driver has failed to probe, users cannot necessarily expect DMA to work anyway, it's still arguable that we should do our best to put things back as if the IOMMU driver was never there at all, and certainly the potential for crashing in iommu-dma itself is undesirable. Make sure we clean up the dev->dma_iommu flag along with everything else.

2025-05-02ACPI: EC: Set ec_no_wakeup for Lenovo Go SMario Limonciello
[ Upstream commit b988685388effd648150aab272533f833a2a70f0 ] When AC adapter is unplugged or plugged in EC wakes from HW sleep but APU doesn't enter back into HW sleep. The reason this happens is that, when the APU exits HW sleep, the power rails controlled by the EC will power up the TCON. The TCON has a GPIO that will be toggled at this time. The GPIO is not marked as a wakeup source, but the GPIO controller still has an unserviced interrupt. Unserviced interrupts will block entering HW sleep again. Clearing the GPIO doesn't help as the TCON continues to assert it until it's been initialized by i2c-hid. Fixing this would require TCON F/W changes and it's already broken in the wild on production hardware. To avoid triggering this issue add a quirk to avoid letting EC wake up system at all. The power button still works properly on this system.
