2008-04-01Input: make sure input interfaces pin parent input devicesDmitry Torokhov1-4/+2
Recent driver core change causes references to parent devices being dropped early, at device_del() time, as opposed to when all children are freed. This causes oops in evdev with grabbed devices. Take the reference to the parent input device ourselves to ensure that it stays around long enough. Signed-off-by: Dmitry Torokhov <[email protected]>
2008-03-30evdev: Release eventual input device grabs when getting disconnectedBjörn Steinbrink1-0/+3
When getting disconnected we need to release eventual grabs on the underlying input device as we also release the input device itself. Otherwise, we would try to release the grab when the client that requested it closes its handle, accessing the input device which might already be freed.

2008-01-21Input: Add proper locking when changing device's keymapDmitry Torokhov1-3/+3
Take dev->event_lock to make sure that we don't race with input_event() and also force key up event when removing a key from keymap table. Signed-off-by: Dmitry Torokhov <[email protected]>
2007-10-19get rid of input BIT* duplicate definesJiri Slaby1-6/+6
get rid of input BIT* duplicate defines use newly global defined macros for input layer. Also remove includes of input.h from non-input sources only for BIT macro definiton. Define the macro temporarily in local manner, all those local definitons will be removed further in this patchset (to not break bisecting). BIT macro will be globally defined (1<<x) Signed-off-by: Jiri Slaby <[email protected]> Cc: <[email protected]> Acked-by: Jiri Kosina <[email protected]> Cc: <[email protected]> Acked-by: Marcel Holtmann <[email protected]> Cc: <[email protected]> Acked-by: Mauro Carvalho Chehab <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2007-06-03Input: reduce raciness when input handlers disconnectDmitry Torokhov1-1/+1
There is a race between input handler's release() and disconnect() methods: when input handler disconnects it wakes up all regular users and then process to walk user list to wake up async. users. While disconnect() walks the list release() removes elements of the same list causing oopses. While this is not a substibute for proper locking we can reduce odds of getting an oops if we wake up normal readers after walking the list. Signed-off-by: Dmitry Torokhov <[email protected]>
2007-05-11Input: evdev - fix overflow in compat_ioctlKenichi Nagai1-1/+1

2006-07-19Input: implement new force feedback interfaceAnssi Hannula1-17/+15
Implement a new force feedback interface, in which all non-driver-specific operations are separated to a common module. This includes handling effect type validations, locking, etc. The effects are now file descriptor specific instead of the previous strange half-process half-fd specific behaviour. The effect memory of devices is not emptied if the root user opens and closes the device while another user is using effects. This is a minor change and most likely no force feedback aware programs are affected by this negatively. Otherwise the userspace interface is left unaltered.

2006-07-06Input: introduce input_inject_event() functionDmitry Torokhov1-3/+3
Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device.

2006-06-23[PATCH] vfs: add lock owner argument to flush operationMiklos Szeredi1-1/+1
Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.
