Sebastian Andrzej Siewior authored
The USB completion callback does not disable interrupts while acquiring the ->lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

The redragon asura keyboard registers two input devices. The initial commit 85455dd9 ("HID: redragon: Fix modifier keys for Redragon Asura Keyboard") considered this an error and prevented one of the devices from registering. However, once this is done the num lock and caps lock leds no longer toggle on and off, although the key functionality is not affected. This commit removes the code that prevents the input device registration and restores the num lock and caps lock LEDs.

Due to the autofs4 module using a file system type name of autofs different from the module containing directory name autoload did not function properly. To work around this kernel configurations have often elected to build the module into the kernel. This can result in selinux policies that prohibit autoloading of the autofs module which need to be changed. Add a comment about this to "possible changes" section of the autofs4 module help.

WHen registering a new binfmt_misc handler, it is possible to overflow the offset to get a negative value, which might crash the system, or possibly leak kernel data.

Most part of these functions was removed in 2012 by Dmitry Kasatkin - 7cf4206a ("Remove unused code from MPI library") - 9e235dca ("Revert "crypto: GnuPG based MPI lib - additional ...") - bc95eead ("lib/mpi: removed unused functions") however headers wwere not updated properly.

percpu_ida() decouples disabling interrupts from the locking operations. This breaks some assumptions if the locking operations are replaced like they are under -RT. The same locking can be achieved by avoiding local_irq_save() and using spin_lock_irqsave() instead. percpu_ida_alloc() gains one more preemption point because after unlocking the fastpath and before the pool lock is acquired, the interrupts are briefly enabled.

Improve the scalability of the IDA by using the per-IDA xa_lock rather than the global simple_ida_lock. IDAs are not typically used in performance-sensitive locations, but since we have this lock anyway, we can use it. It is also a step towards converting the IDA from the radix tree to the XArray.
