2012-11-15Second step of revamping the build systemAnthony G. Basile
The original Makefile.am was drawn to the top level. This commit breaks it out into the various directories with SUBDIRS connecting them. This makes each directory easier to maintain.
2012-11-15Isolation of udev code from remaining systemdAnthony G. Basile
This commit is a first attempt to isolate the udev code from the remaining code base. It intentionally does not modify any files but purely delete files which, on a first examination, appear to not be needed. This is a sweeping commit which may easily have missed needed code. Files can be retrieved by doing a checkout from the previous commit: git checkout 2944f347d0 -- <filename>
2012-11-13udev: properly handle symlink removal by 'change' eventKay Sievers
If a 'change' event is supposed to remove created symlinks, we create a new device structure from the sysfs device and fill it with the list of links, to compute the delta of the old and new list of links to apply. If the device is already 'remove'd by the kernel though, udev fails to create the device structure, so the links are not removed properly. > From: Neil Brown <nfbrown@suse.com> > Date: Thu, 8 Nov 2012 10:39:06 +0100 > Subject: [PATCH] If a 'change' event does not get handled by udev until > after the device has subsequently disappeared, udev mis-handles > it. This can happen with 'md' devices which emit a change > event and then a remove event when they are stopped. It is > normally only noticed if udev is very busy (lots of arrays > being stopped at once) or the machine is otherwise loaded > and reponding slowly. > > There are two problems. > > 1/ udev_device_new_from_syspath() will refuse to create the device > structure if the device does not exist in /sys, and particularly if > the uevent file does not exist. > If a 'db' file does exist, that is sufficient evidence that the device > is genuine and should be created. Equally if we have just received an > event from the kernel about the device, it must be real. > > This patch just disabled the test for the 'uevent' file, it doesn't > try imposing any other tests - it isn't clear that they are really > needed. > > 2/ udev_event_execute_rules() calls udev_device_read_db() on a 'device' > structure that is largely uninitialised and in particular does not > have the 'subsystem' set. udev_device_read_db() needs the subsystem > so it tries to read the 'subsystem' symlink out of sysfs. If the > device is already deleted, this naturally fails. > udev_event_execute_rules() knows the subsystem (as it was in the > event message) so this patch simply sets the subsystem for the device > structure to be loaded to match the subsystem of the device structure > that is handling the event. > > With these two changes, deleted handling of change events will still > correctly remove any symlinks that are not needed any more. Use udev_device_new() instead of allowing udev_device_new_from_syspath() to proceed without a sysfs device.

2012-10-19keymap: Tolerate invalid entries in keymapsMartin Pitt
Some keymaps apply to a large range of computer models, not all of which have all of the scan codes in the maps. If a single scan code is invalid, do not abort but continue with the next entry in the map. Instead just show the error message for that particular scan code, to help with debugging.
2012-10-19keymap: Fix parsing of hex scan codes in tablesMartin Pitt
Commit b1f87c76b1 changed sscanf from %i to %u, as scan codes are unsigned numbers which can be > 0x7FFFFFFF. However, sscanf doesn't accept hexadecimal numbers for %u. It works fine with %i, so revert this back.

Add support for scm block devices. Introduced here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=f30664e2 Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com>
2012-10-10keymap: Fix scan codes > 0x7FFFFFFFMartin Pitt
According to Linux drivers/input/evdev.c, scan codes are unsigned, not int nor uint32_t. Thanks to Dejan Tosovic <dejan@post.com> for reporting this!

2012-10-07udev: allow firmware requests to bypass the dependency trackingKay Sievers
The removal of the TIMEOUT= handling in udevd put firmware requests into the devpath parent/child dependency tracking. Drivers which block in module_init() asking userspace for firmware ran into a 30 sec device timeout. The whole firmware loading willl hopefully move into the kernel and the fragile-since-day-one fake async driver-core device dance involving udev can be retired: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=abb139e75c2cdbb955e840d6331cb5863e409d0e
