2022-05-19Input: ili210x - fix reset timingMarek Vasut1-2/+2
According to Ilitek "231x & ILI251x Programming Guide" Version: 2.30 "2.1. Power Sequence", "T4 Chip Reset and discharge time" is minimum 10ms and "T2 Chip initial time" is maximum 150ms. Adjust the reset timings such that T4 is 12ms and T2 is 160ms to fit those figures. This prevents sporadic touch controller start up failures when some systems with at least ILI251x controller boot, without this patch the systems sometimes fail to communicate with the touch controller.

2022-04-01Revert "Input: clear BTN_RIGHT/MIDDLE on buttonpads"José Expósito1-6/+0
This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40. The touchpad present in the Dell Precision 7550 and 7750 laptops reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However, the device is not a clickpad, it is a touchpad with physical buttons. In order to fix this issue, a quirk for the device was introduced in libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property: [Precision 7x50 Touchpad] MatchBus=i2c MatchUdevType=touchpad MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50* AttrInputPropDisable=INPUT_PROP_BUTTONPAD However, because of the change introduced in 37ef4c19b4 ("Input: clear BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped anymore breaking the device right click button and making impossible to workaround it in user space. In order to avoid breakage on other present or future devices, revert the patch causing the issue.

Add support for the IST3038C touchscreen IC from Imagis, based on downstream driver. The driver supports multi-touch (10 touch points) The IST3038C IC supports touch keys, but the support isn't added because the touch screen used for testing doesn't utilize touch keys. Looking at the downstream driver, it is possible to add support for other Imagis ICs of IST30**C series.

We need to support parsing the HID device in both the Vivaldi and the Hammer drivers so that we can properly expose the function row physmap to userspace when a hammer device uses a vivaldi keyboard layout for the function row keys. Extract the feature mapping logic from the vivaldi driver into an hid specific vivaldi library so we can use it from both HID drivers. To allow more code sharing we mandate that vivaldi data must be placed at the very beginning of the driver data attached to the HID device instance.

Command 'ip link ... set nomaster' causes that ice_plug_aux_dev() is called from ice_service_task() context, aux device is created and associated device->lock is taken. 2. Command 'ip link ... set master...' calls ice's notifier under RTNL lock and that notifier calls ice_unplug_aux_dev(). That function tries to take aux device->lock but this is already taken by ice_plug_aux_dev() in step 1 3. Later ice_plug_aux_dev() tries to take RTNL lock but this is already taken in step 2 4. Dead-lock The patch fixes this issue by following changes: - Bit ICE_FLAG_PLUG_AUX_DEV is kept to be set during ice_plug_aux_dev() call in ice_service_task() - The bit is checked in ice_clear_rdma_cap() and only if it is not set then ice_unplug_aux_dev() is called. If it is set (in other words plugging of aux device was requested and ice_plug_aux_dev() is potentially running) then the function only clears the bit - Once ice_plug_aux_dev() call (in ice_service_task) is finished the bit ICE_FLAG_PLUG_AUX_DEV is cleared but it is also checked whether it was already cleared by ice_clear_rdma_cap(). If so then aux device is unplugged.

Ideally if there isn't a wol_irq, or there is something else that keeps the device from being able to wakeup it should display: "Supports Wake-on: d" This patch checks whether the device can wakup, before using the hard-coded supported flags. This corrects the ethtool reporting, as well as the WOL configuration because ethtool verifies that the mode is supported before attempting it.

If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished. The xenbus driver has a similar problem, as it doesn't check the success of removing the granted access of a shared ring buffer. - blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. - netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path.

2022-03-09net/mlx5: Fix a race on command flush flowMoshe Shemesh1-7/+8
Fix a refcount use after free warning due to a race on command entry. Such race occurs when one of the commands releases its last refcount and frees its index and entry while another process running command flush flow takes refcount to this command entry. The process which handles commands flush may see this command as needed to be flushed if the other process released its refcount but didn't release the index yet. Fix it by adding the needed spin lock. It fixes the following warning trace: refcount_t: addition on 0; use-after-free. WARNING: CPU: 11 PID: 540311 at lib/refcount.c:25 refcount_warn_saturate+0x80/0xe0 ... RIP: 0010:refcount_warn_saturate+0x80/0xe0 ...

2022-03-09net:mcf8390: Use platform_get_irq() to get the interruptMinghao Chi (CGEL ZTE)1-5/+5
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ) for requesting IRQ's resources any more, as they can be not ready yet in case of DT-booting. platform_get_irq() instead is a recommended way for getting IRQ even if it was not retrieved earlier. It also makes code simpler because we're getting "int" value right away and no conversion from resource to int is required.
