ALSA: timer: Remove kernel warning at compat ioctl error paths

2018-02-13T18:32:19Z

commit 3d4e8303f2c747c8540a0a0126d0151514f6468b upstream. Some timer compat ioctls have NULL checks of timer instance with snd_BUG_ON() that bring up WARN_ON() when the debug option is set. Actually the condition can be met in the normal situation and it's confusing and bad to spew kernel warnings with stack trace there. Let's remove snd_BUG_ON() invocation and replace with the simple checks. Also, correct the error code to EBADFD to follow the native ioctl error handling.

ALSA: timer: Add missing mutex lock for compat ioctls

2018-01-01T20:51:00Z

commit 79fb0518fec8c8b4ea7f1729f54f293724b3dbb0 upstream. The races among ioctl and other operations were protected by the commit af368027a49a ("ALSA: timer: Fix race among timer ioctls") and later fixes, but one code path was forgotten in the scenario: the 32bit compat ioctl. As syzkaller recently spotted, a very similar use-after-free may happen with the combination of compat ioctls. The fix is simply to apply the same ioctl_lock to the compat_ioctl callback, too.

ALSA: timer: Fix broken compat timer user status ioctl

2016-04-01T00:54:35Z

commit 3a72494ac2a3bd229db941d51e7efe2f6ccd947b upstream. The timer user status compat ioctl returned the bogus struct used for 64bit architectures instead of the 32bit one. This patch addresses it to return the proper struct. Signed-off-by: Takashi Iwai Signed-off-by: Ben Hutchings

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
