* Input: scancode in get/set_keycodes should be unsignedDmitry Torokhov2010-03-091-1/+1
| | | | | | | | | | | | The HID layer has some scan codes of the form 0xffbc0000 for logitech devices which do not work if scancode is typed as signed int, so we need to switch to unsigned it instead. While at it keycode being signed does not make much sense either.

* Input: mark input interfaces as non-seekableDmitry Torokhov2010-02-041-0/+2
| | | | | | | Seeking does not make sense for input interfaces such as evdev and joydev so let's use nonseekable_open to mark them non-seekable. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
* Input: evdev - be less aggressive about sending SIGIO notifiesAdam Jackson2010-01-061-1/+2
| | | | | | | | | | | | | | | | | | When using realtime signals, we'll enqueue one signal for every event. This is unfortunate, because (for example) keyboard presses are three events: key, msc scancode, and syn. They'll be enqueued fast enough in kernel space that all three events will be ready to read by the time userspace runs, so the first invocation of the signal handler will read all three events, but then the second two invocations still have to run to do no work. Instead, only send the SIGIO notification on syn events. This is a slight abuse of SIGIO semantics, in principle it ought to fire as soon as any events are readable. But it matches evdev semantics, which is more important since SIGIO is rather vaguely defined to begin with.

* Input: fix EVIOCGNAME/JSIOCGNAME regressionDaniel Mack2009-07-141-2/+1Star
| | | | | | | | | | | | | | | | | Commit 3d5cb60e ("Input: simplify name handling for certain input handles") introduced a regression for the EVIOCGNAME/JSIOCGNAME ioctl. Before this, patch, the platform device's name was given back to userspace which was good to identify devices. After this patch, the device is ("event%d", minor) which is not descriptive at all. This fixes the behaviour by taking dev->name.

* Rationalize fasync return valuesJonathan Corbet2009-03-161-4/+1Star
| | | | | | | | | | | | | | | | | | | | Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

| * saner FASYNC handling on file closeAl Viro2008-11-011-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
