Cap slot values to the announced maximum

A malicious device may announce N slots but then send a slot index >= N. The
slot state is almost always allocated (definitely the case in libevdev and
true for most callers), so providing a slot number higher than the announced
maximum is likely to lead to invalid dereferences. Don't allow that.
Likewise, don't allow negative slot numbers.

Note that the kernel filters these events anyway, the only way to trigger this
is to change the device fd to something outside the kernel's control.

Peter Hutterer [Thu, 27 Feb 2014 03:10:35 +0000 (13:10 +1000)]
Reduce memory requirement for MT syncing

Changes the algorithm: before we'd ioctl all axes for all slots, then generate
events for all slots one-by-one.

Now we ioctl the slot state for each axis, copy the new event value into
the device and mark a bitfield that we've updated the value. Then loop through
the slots and generate events where changed.

Side-effect: this makes it easy to check if anything in the slot has updated,
so we can skip empty slot events during sync.

Min memory requirement for the state storage was:
  MAX_SLOTS  * (ABS_MT_CNT + 1) * sizeof(int) = 1980
Min memory requirement now:
  (ABS_MT_CNT + 1) * sizeof(int) + NLONGS((MAX_SLOTS * ABS_MT_CNT) bits) = 544

This is sigsafe code, so this was stack memory. Reducing the requirement
allows us to up MAX_SLOTS in the future if we need to.

Require autoconf 2.62

According to Gaetan, that's what we really require. And as a bonus point, this makes libevdev build
on RHEL6 out-of-the-box.

Check max to see if an event type is valid

There's a gap in the range between EV_SW and EV_LED. Trying to enable one
of those bits will segfault.

11 years agoReset the struct on set_fd

Reset the struct on set_fd

libevdev_set_fd may fail at a number of points. If it does, it errors out but does nothing
otherwise. Thus, a client may call set_fd again for the same struct but on a different fd and have
it succeed. Depending on when set_fd bailed out the first time, some fields may already be set.

Thus, reset the whole struct at set_fd time to make sure we're nulled out appropriately.
