Author: Maíra Canal <[email protected]> Date: Wed Jan 22 22:24:03 2025 -0300 drm/v3d: Assign job pointer to NULL before signaling the fence commit 6e64d6b3a3c39655de56682ec83e894978d23412 upstream. In commit e4b5ccd392b9 ("drm/v3d: Ensure job pointer is set to NULL after job completion"), we introduced a change to assign the job pointer to NULL after completing a job, indicating job completion. However, this approach created a race condition between the DRM scheduler workqueue and the IRQ execution thread. As soon as the fence is signaled in the IRQ execution thread, a new job starts to be executed. This results in a race condition where the IRQ execution thread sets the job pointer to NULL simultaneously as the `run_job()` function assigns a new job to the pointer. This race condition can lead to a NULL pointer dereference if the IRQ execution thread sets the job pointer to NULL after `run_job()` assigns it to the new job. When the new job completes and the GPU emits an interrupt, `v3d_irq()` is triggered, potentially causing a crash.

Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a dedicated keycode, and multiple vendors have their keyboards emit this sequence in response to users pressing a dedicated "Copilot" key. Unfortunately the default keymap table in atkbd does not map scancode 0x6e (F23) and so the key combination does not work even if userspace is ready to handle it. Because this behavior is common between multiple vendors and the scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that key sequence is generated properly. MS documentation for the scan code: https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes Confirmed on Lenovo, HP and Dell machines by Canonical.

Since the power key is connected to the PMIC, and people expect to wake up a suspended system via this key, the NMI IRQ controller must stay alive when the system goes into suspend. Add the SKIP_WAKE flag to prevent the sunxi NMI controller from going to sleep, so that the power key can wake up those systems.

At the end of __regmap_init(), if dev is not NULL, regmap_attach_dev() is called, which adds a devres reference to the regmap, to be able to retrieve a dev's regmap by name using dev_get_regmap(). When calling regmap_exit, the opposite does not happen, and the reference is kept until the dev is detached. Add a regmap_detach_dev() function and call it in regmap_exit() to make sure that the devres reference is not kept.

If there's a persistent error in the hypervisor, the SCSI warning for failed I/O can flood the kernel log and max out CPU utilization, preventing troubleshooting from the VM side. Ratelimit the warning so it doesn't DoS the VM.

This patch addresses a null-ptr-deref in qt2_process_read_urb() due to an incorrect bounds check in the following: if (newport > serial->num_ports) { dev_err(&port->dev, "%s - port change to invalid port: %i\n", __func__, newport); break; } The condition doesn't account for the valid range of the serial->port buffer, which is from 0 to serial->num_ports - 1. When newport is equal to serial->num_ports, the assignment of "port" in the following code is out-of-bounds and NULL: serial_priv->current_port = newport; port = serial->port[serial_priv->current_port]; The fix checks if newport is greater than or equal to serial->num_ports indicating it is out-of-bounds.
