2014-06-15udev: check the return value from udev_enumerate_scan_devicesThomas Hindoe Paaboel Andersen
The return value from udev_enumerate_scan_devices was stored but never used. I assume this was meant to be checked. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-06-15udev: really exclude device-mapper from block device ownership event lockingChristian Hesse
Arguments were wrong order, no? This fixes commits: e918a1b5a94f270186dca59156354acd2a596494 3d06f4183470d42361303086ed9dedd29c0ffc1b Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-06-07udev: make sure we always get "change" for the diskKay Sievers
The kernel will return 0 for REREADPT when no partition table is found, we have to send out "change" ourselves. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-06-07udev: synthesize "change' events for partitions when tools change the diskKay Sievers
This should make sure that fdisk-like programs will automatically cause an update of all partitions, just like mkfs-like programs cause an update of the partition. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-06-01udev-builtin-keyboard: do tell on which device EVIOCSKEYCODE failed.Cristian Rodríguez
I am getting "Error calling EVIOCSKEYCODE (scan code 0xc022d, key code 418): Invalid argument", the error message does not tell on which specific device the problem is, add that info. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-05-23udevadm-settle: fixed return code for empty queueHarald Hoyer
If the udev queue is empty and "/run/udev/queue" does not exist, "udevadm settle" would return with EXIT_FAILURE, because the inotify on "/run/udev/queue" would fail with ENOENT. This patch lets "udevadm settle" exit with EXIT_SUCCESS in this case. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-05-17udev: avoid use of uninitialized errThomas Hindoe Paaboel Andersen
After 1ea972174baba40dbc80c51cbfc4edc49764b59b err is no longer set unless we hit a special case. Initialize it to 0 and remove a check that will never fail. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-04-24udev: increase the size of RESULT bufferRobert Milasan
Under some conditions, in udev_rules_apply_to_event the fact that result is 1024 bytes, creates problems if the output of the running command/app is bigger then 1024 bytes. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-04-24udev: remove seqnum API and all assumptions about seqnumsKay Sievers
The way the kernel namespaces have been implemented breaks assumptions udev made regarding uevent sequence numbers. Creating devices in a namespace "steals" uevents and its sequence numbers from the host. It confuses the "udevadmin settle" logic, which might block until util a timeout is reached, even when no uevent is pending. Remove any assumptions about sequence numbers and deprecate libudev's API exposing these numbers; none of that can reliably be used anymore when namespaces are involved. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-03-28udev: persistent naming - we cannot use virtio numbers as they are not stableTom Gundersen
This reverts commit 8741f2defaf26aafe5ee0fd29954cfdf84ee519c: 'Add virtio-blk support to path_id' and commit e3d563346c4237af23335cc6904e0662efdf62ad: 'udev: net_id - handle virtio buses'. Distros may want to take note of this, as it changes behavior. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-03-17input_id: Recognize buttonless joystick typesMartin Pitt
Input devices like rudders or pedals are joystick-like; they don't have buttons, but axes like RX, THROTTLE, or RUDDER. These don't interfere with other device types with absolute axes (touch screens, touchpads, and accelerometers), so it's fairly safe to mark them as ID_INPUT_JOYSTICK and thus hand out dynamic ACLs to the user. https://bugs.freedesktop.org/show_bug.cgi?id=70734
2014-03-17udev: properly detect reference to unexisting part of PROGRAM's resultLukas Nykryn
2014-03-17Use strlen even for constant stringsJosh Triplett
GCC optimizes strlen("string constant") to a constant, even with -O0. Thus, replace patterns like sizeof("string constant")-1 with strlen("string constant") where possible, for clarity. In particular, for expressions intended to add up the lengths of components going into a string, this often makes it clearer that the expression counts the trailing '\0' exactly once, by putting the +1 for the '\0' at the end of the expression, rather than hidden in a sizeof in the middle of the expression.

If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

Use PID_FMT/USEC_FMT/... in more places. Also update logind error messages to print the full path to a file that failed. This should make debugging easier for people who do not know off the top of their head where logind stores it state. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-02-02use memzero(foo, length); for all memset(foo, 0, length); callsGreg KH
In trying to track down a stupid linker bug, I noticed a bunch of memset() calls that should be using memzero() to make it more "obvious" that the options are correct (i.e. 0 is not the length, but the data to set). So fix up all current calls to memset(foo, 0, length) to memzero(foo, length). Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-01-20udev/udevadm-hwdb.c: remove usage of qsort_rrofl0r
while theoretically a nice interface, qsort_r on GLIBC was implemented with a prototype that shuffles the argument order around when compared to the traditional BSD implementations, yielding in 2 separate incompatible implementations. even worse, the arguments are all of pointer type so one would not even notice that the order is wrong and so this would yield in crashes or silent memory corruption. thus musl does not implement it, because configure scripts would check for its existance and use it unconditionally, even when assuming the BSD version. a more portable solution is to use TLS via __thread, which any modern GCC should provide. (even 3.4.6 on x86/x86_64 does so). Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
