2023-10-18net: mdio-mux: fix C45 access returning -EIO after API changeVladimir Oltean1-0/+47
The mii_bus API conversion to read_c45() and write_c45() did not cover the mdio-mux driver before read() and write() were made C22-only. This broke arch/arm64/boot/dts/freescale/fsl-ls1028a-qds-13bb.dtso. The -EOPNOTSUPP from mdiobus_c45_read() is transformed by get_phy_c45_devs_in_pkg() into -EIO, is further propagated to of_mdiobus_register() and this makes the mdio-mux driver fail to probe the entire child buses, not just the PHYs that cause access errors. Fix the regression by introducing special c45 read and write accessors to mdio-mux which forward the operation to the parent MDIO bus.

2023-10-18nvmet-auth: complete a request only after freeing the dhchap pointersMaurizio Lombardi1-3/+6
It may happen that the work to destroy a queue (for example nvmet_tcp_release_queue_work()) is started while an auth-send or auth-receive command is still completing. nvmet_sq_destroy() will block, waiting for all the references to the sq to be dropped, the last reference is then dropped when nvmet_req_complete() is called. When this happens, both nvmet_sq_destroy() and nvmet_execute_auth_send()/_receive() will free the dhchap pointers by calling nvmet_auth_sq_free(). Since there isn't any lock, the two threads may race against each other, causing double frees and memory corruptions, as reported by KASAN.

The function vp_modern_map_capability() takes the size parameter, which corresponds to the size of virtio_pci_common_cfg. As a result, this indicates the size of memory area to map. Now the size is the size of virtio_pci_common_cfg, but some feature(such as the _F_RING_RESET) needs the virtio_pci_modern_common_cfg, so this commit changes the size to the size of virtio_pci_modern_common_cfg.

2023-10-18vhost: Allow null msg.size on VHOST_IOTLB_INVALIDATEEric Auger1-3/+1
Commit e2ae38cf3d91 ("vhost: fix hung thread due to erroneous iotlb entries") Forbade vhost iotlb msg with null size to prevent entries with size = start = 0 and last = ULONG_MAX to end up in the iotlb. Then commit 95932ab2ea07 ("vhost: allow batching hint without size") only applied the check for VHOST_IOTLB_UPDATE and VHOST_IOTLB_INVALIDATE message types to fix a regression observed with batching hit. Still, the introduction of that check introduced a regression for some users attempting to invalidate the whole ULONG_MAX range by setting the size to 0. This is the case with qemu/smmuv3/vhost integration which does not work anymore. It Looks safe to partially revert the original commit and allow VHOST_IOTLB_INVALIDATE messages with null size. vhost_iotlb_del_range() will compute a correct end iova.

A firmware error is triggered when configuring a 9k MTU on the PF after switching to switchdev mode and then using a vdpa device with larger (1k) rings: mlx5_cmd_out_err: CREATE_GENERAL_OBJECT(0xa00) op_mod(0xd) failed, status bad resource(0x5), syndrome (0xf6db90), err(-22) This is due to the fact that the hw VQ size parameters are computed based on the umem_1/2/3_buffer_param_a/b capabilities and all device capabilities are read only when the driver is moved to switchdev mode. The problematic configuration flow looks like this: 1) Create VF 2) Unbind VF 3) Switch PF to switchdev mode. 4) Bind VF 5) Set PF MTU to 9k 6) create vDPA device 7) Start VM with vDPA device and 1K queue size Note that setting the MTU before step 3) doesn't trigger this issue. This patch reads the forementioned umem parameters at the latest point possible before the VQs of the device are created. v2: - Allocate output with kmalloc to reduce stack frame size. - Removed stable from cc.

2023-10-18platform/x86: asus-wmi: Only map brightness codes when using asus-wmi ↵Hans de Goede1-11/+4
backlight control Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. This mapping is really only necessary when asus-wmi has registered a backlight-device for backlight control. In this case the mapping was used to decide to filter out the keypresss since in this case the firmware has already modified the brightness itself and instead of reporting a keypress asus-wmi will just report the new brightness value to userspace. OTOH when the firmware does not adjust the brightness itself then it seems to always report 0x2e for brightness-down presses and 0x2f for brightness up presses independent of the actual brightness level. So in this case the mapping of the code is not necessary and this translation actually leads to spurious brightness-down presses being send to userspace when pressing printscreen or capslock. Modify asus_wmi_handle_event_code() to only do the mapping when using asus-wmi backlight control to fix the spurious brightness-down presses.

2023-10-18platform/x86: asus-wmi: Change ASUS_WMI_BRN_DOWN code from 0x20 to 0x2eHans de Goede1-1/+1
Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX aka 0x20 - 0x2e events were mapped to 0x20. This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. The plan is disable the 0x11-0x2e special mapping on laptops where asus-wmi does not register a backlight-device to avoid the spurious brightness-down keypresses. New laptops always send 0x2e for brightness-down presses, change the special internal ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in preparation for fixing the spurious brightness-down presses. This change does not have any functional impact since all of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only then checked against the keymap code and the new 0x2e value is still in the 0x20 - 0x2e range.

2023-10-17drm/i915: Retry gtt fault when out of fence registersVille Syrjälä1-0/+1
If we can't find a free fence register to handle a fault in the GMADR range just return VM_FAULT_NOPAGE without populating the PTE so that userspace will retry the access and trigger another fault. Eventually we should find a free fence and the fault will get properly handled. A further improvement idea might be to reserve a fence (or one per CPU?) for the express purpose of handling faults without having to retry. But that would require some additional work. Looks like this may have gotten broken originally by commit 39965b376601 ("drm/i915: don't trash the gtt when running out of fences") as that changed the errno to -EDEADLK which wasn't handle by the gtt fault code either. But later in commit 2feeb52859fc ("drm/i915/gt: Fix -EDEADLK handling regression") I changed it again to -ENOBUFS as -EDEADLK was now getting used for the ww mutex dance. So this fix only makes sense after that last commit.

2023-10-17iio: afe: rescale: Accept only offset channelsLinus Walleij1-4/+15
As noted by Jonathan Cameron: it is perfectly legal for a channel to have an offset but no scale in addition to the raw interface. The conversion will imply that scale is 1:1. Make rescale_configure_channel() accept just scale, or just offset to process a channel. When a user asks for IIO_CHAN_INFO_OFFSET in rescale_read_raw() we now have to deal with the fact that OFFSET could be present but SCALE missing. Add code to simply scale 1:1 in this case.
