* udev: event - move renaming of udev_device to libudevTom Gundersen2015-01-261-13/+15
| | | | | This is not exposed in the public API. We want to simplify the internal libudev-device API as much as possible so that it will be simpler to rip the whole thing out in the future.
* Assorted format fixesZbigniew Jędrzejewski-Szmek2015-01-221-10/+10
| | | | | Types used for pids and uids in various interfaces are unpredictable. Too bad.
* treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt2014-11-281-12/+12
| | | | | | | | | | | If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
* treewide: yet more log_*_errno + return simplificationsMichal Schmidt2014-11-281-4/+2
| | | | | | | | | | | | | Using: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/(if\s*\([^\n]+\))\s*{\n(\s*)(log_[a-z_]*_errno\(\s*([->a-zA-Z_]+)\s*,[^;]+);\s*return\s+\g4;\s+}/\1\n\2return \3;/msg; print;' $f done And a couple of manual whitespace fixups.

* udev: fix path for database names on 'change' eventRobert Milasan2014-09-181-0/+1
| | | | | | | | | | | If a device does not have a major/minor number attached, we use different database names than if it does. On "change" events, we didn't copy the devnum over, therefore, we used different paths than on 'add' or 'remove' events (where devnum was properly copied). Fix this by always copying the devnum into the udev-device. (David: added commit-log from email)

|
* udev: netif_rename - don't log to kmsgTom Gundersen2014-09-091-1/+1
| | | | As of 3.17, the kernel will do this on its own, so just do regular log_debug() logging from udev.
* udev: event - keep one rtnl per worker, rather than per eventTom Gundersen2014-09-091-15/+8
| | | | | | | | Creating the rtnl context is cheap, but freeing it may not be, due to synchronous close(). Also drop some excessive logging. We now log about the changing ifname exactly once.

* api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering2014-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.

* rtnl: drop "sd_" prefix from cleanup macrosLennart Poettering2014-02-131-1/+1
| | | | | | | | | The "sd_" prefix is supposed to be used on exported symbols only, and not in the middle of names. Let's drop it from the cleanup macros hence, to make things simpler. The bus cleanup macros don't carry the "sd_" either, so this brings the APIs a bit nearer.
* use memzero(foo, length); for all memset(foo, 0, length); callsGreg KH2014-01-311-2/+2
| | | | | | | | 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).

* udev: properly handle symlink removal by 'change' eventKay Sievers2012-11-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
