2015-05-03udev: keyboard-builtin: Add support for setting IBM trackpoint sensitivityHans de Goede
IBM / Lenovo trackpoints allow specifying a sensitivity setting through a ps/2 command, which changes the range of the deltas sent when using the trackpoint. On some models with normal usage only deltas of 1 or 2 are send, resulting in there only being 2 mouse cursor movement speeds, rather than the expected fluid scale. Changing the sensitivity to a higher level than the bootup default fixes this. This commit adds support for setting a POINTINGSTICK_SENSITIVITY value in hwdb to allow changing the sensitivity on boot through udev / hwdb. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-04-12udevd: fix synchronization with settle when handling inotify eventsDaniel Drake
udev uses inotify to implement a scheme where when the user closes a writable device node, a change uevent is forcefully generated. In the case of block devices, it actually requests a partition rescan. This currently can't be synchronized with "udevadm settle", i.e. this is not reliable in a script: sfdisk --change-id /dev/sda 1 81 udevadm settle mount /dev/sda1 /foo The settle call doesn't synchronize there, so at the same time we try to mount the device, udevd is busy removing the partition device nodes and readding them again. The mount call often happens in that moment where the partition node has been removed but not readded yet. This exact issue was fixed long ago: http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=bb38678e3ccc02bcd970ccde3d8166a40edf92d3 but that fix is no longer valid now that sequence numbers are no longer used. Fix this by forcing another mainloop iteration after handling inotify events before unblocking settle. If the inotify event caused us to generate a "change" event, we'll pick that up in the following loop iteration, before we reach the end of the loop where we respond to settle's control message, unblocking it.

2015-04-12udev: restore udevadm settle timeoutNir Soffer
Commit 9ea28c55a2 (udev: remove seqnum API and all assumptions about seqnums) introduced a regresion, ignoring the timeout option when waiting until the event queue is empty. Previously, if the udev event queue was not empty when the timeout was expired, udevadm settle was returning with exit code 1. To check if the queue is empty, you could invoke udevadm settle with timeout=0. This patch restores the previous behavior. (David: fixed timeout==0 handling and dropped redundant assignment) Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-04-12udev: builtin-keyboard: add support for EVDEV_ABS_*Anthony G. Basile
Parse properties in the form EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>" and apply them to the kernel device. Future processes that open that device will see the updated EV_ABS range. This is particularly useful for touchpads that don't provide a resolution in the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974). All values in the property are optional, e.g. a string of "::45" is valid to set the resolution to 45. The order intentionally orders resolution before fuzz and flat despite it being the last element in the absinfo struct. The use-case for setting fuzz/flat is almost non-existent, resolution is probably the most common case we'll need. To avoid multiple hwdb invocations for the same device, replace the hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules file. The new 60-evdev.rules is called for all event nodes anyway, we don't need a separate rules file and second callout to the hwdb builtin. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-04-12udev: builtin-keyboard: move actual key mapping to a helper functionPeter Hutterer
No changes in the mapping, but previously we opened the device only on successful parsing. Now we open the mapping as soon as we have a value that looks interesting. Since errors are supposed to be the exception, not the rule, this is probably fine. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-04-12udev: builtin-keyboard: immediately EVIOCSKEYCODE when we have a pairPeter Hutterer
Rather than building a map and looping through the map, immediately call the ioctl when we have a successfully parsed property. This has a side-effect: before the maximum number of ioctls was limited to the size of the map (1024), now it is unlimited. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-04-12udev: builtin-keyboard: move fetching the device node upPeter Hutterer

2015-04-12udev: input_id: tag accelerometers as ID_INPUT_ACCELEROMETERHans de Goede
input_id already (tries to) tag accelerometers as such, but this only works for absolute accelerometers. Recent kernels mark accelerometers through an input prop. Trust that prop and always tag devices with it with ID_INPUT_ACCELEROMETER. Note that detection by the prop bit works the same as the existing detection and will ensure that no other tags get set on the device. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-04-12udev: input_id: tag pointing sticks as ID_INPUT_POINTINGSTICKAnthony G. Basile
Also referred to as trackpoint, trackstick. These are marked by recent kernels through an input prop. Forward that prop as udev property so userspace can easily determine whether there is a pointing stick present. These devices were previously marked as ID_INPUT_MOUSE, for backwards compatibility we keep that in place, the new property is an addition.y Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-03-18selinux: fix SEGV during switch-root if SELinux policy loadedWill Woods
If you've got SELinux policy loaded, label_hnd is your labeling handle. When systemd is shutting down, we free that handle via mac_selinux_finish(). But: switch_root() calls mkdir_p_label(), which tries to look up a label using that freed handle, and so we get a bunch of garbage and eventually SEGV in libselinux. (This doesn't happen in the switch-root from initramfs to real root because there's no SELinux policy loaded in initramfs, so label_hnd is NULL and we never attempt any lookups.) So: make sure that mac_selinux_finish() actually sets label_hnd to NULL, so nobody tries to use it after it becomes invalid. https://bugzilla.redhat.com/show_bug.cgi?id=1185604 Signed-off-by: Anthony G.
