ALSA dummy driver can switch the timer backend between system timer and hrtimer via its hrtimer module option. This can be also switched dynamically via sysfs, but it may lead to a memory corruption when switching is done while a PCM stream is running; the stream instance for the newly switched timer method tries to access the memory that was allocated by another timer method although the sizes differ. As the simplest fix, this patch just disables the switch via sysfs by dropping the writable bit.

KEY_FLAG_KEEP should only be applied to a key if the keyring it is being linked into has KEY_FLAG_KEEP set.

Without undoing this change, it becomes impossible to delete, revoke or invalidate keys added to keyrings through __key_instantiate_and_link() where the keyring has itself been linked to. To test this, run the following command sequence: keyctl newring foo @s keyctl add user a a %:foo keyctl unlink %user:a %:foo keyctl clear %:foo With the commit mentioned above the third and fourth commands fail with EPERM when they should succeed.

Runtime suspend during driver probe and removal can cause problems. The driver's runtime_suspend or runtime_resume callbacks may invoked before the driver has finished binding to the device or after the driver has unbound from the device. This problem shows up with the sd and sr drivers, and can cause disk or CD/DVD drives to become unusable as a result. The fix is simple. The drivers store a pointer to the scsi_disk or scsi_cd structure as their private device data when probing is finished, so we simply have to be sure to clear the private data during removal and test it during runtime suspend/resume.
