2015-03-13udev: make set_usec_initialized() internal to libudevTom Gundersen
Instead introduce ensure_usec_initialized(), which copies the timestamp if possible otherwise sets it to now(CLOCK_MONOTONIC).
2015-03-13udev: dont use EWOULDBLOCKDavid Herrmann
EWOULDBLOCK is the same as EAGAIN, stop using it.
2015-03-12udevd: improve handling of failed workerTom Gundersen
The information in the db is stale, so it does not make sense to expose it any longer. Also, don't drop the kernel event, but simply pass it on to userspace without ammending it.
2015-03-12udevd: don't free event when killing the worker, wait until it has been reapedTom Gundersen
This will allow us to clean up the device when we are notified about the worker being killed.
2015-03-09udev: simplify event_queue_update() and add debug loggingTom Gundersen
This essentially replaces open("/run/udev/queue", O_WRONLY|O_CREAT|O_CLOEXEC|O_TRUNC|O_NOFOLLOW, 0444) with open("/run/udev/queue", O_WRONLY|O_CREAT|O_CLOEXEC|O_NOCTTY, 0644), which is ok for our purposes.
2015-03-09udevd: close race in udev settleTom Gundersen
The udev-settle guarantees that udevd is no longer processing any of the events casued by udev-trigger. The way this works is that it sends a synchronous PING to udevd after udev-trigger has ran, and when that returns it knows that udevd has started processing the events from udev-trigger. udev-settle will then wait for the event queue to empty before returning. However, there was a race here, as we would only update the /run state at the beginning of the event loop, before reading out new events and before processing the ping. That means that if the first uevent arrived in the same event-loop iteration as the PING, we would return the ping before updating the queue state in /run (which would happen on the next iteration). The race window here is tiny (as the /run state would probably get updated before udev-settle got a chance to read /run), but still a possibility. Fix the problem by updating the /run state as the last step before returning the PING. We must still update it at the beginning of the loop as well, otherwise we risk being stuck in poll() with a stale state in /run. Reported-by: Daniel Drake <drake@endlessm.com>
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-12include <poll.h> instead of <sys/poll.h>Thomas Hindoe Paaboel Andersen
include-what-you-use automatically does this and it makes finding unnecessary harder to spot. The only content of poll.h is a include of sys/poll.h so should be harmless.
2015-01-22Assorted format fixesZbigniew Jędrzejewski-Szmek
Types used for pids and uids in various interfaces are unpredictable. Too bad.

2014-12-24util: fix strict aliasing violations in use of struct inotify_event v5Shawn Paul Landden
There is alot of cleanup that will have to happen to turn on -fstrict-aliasing, but I think our code should be "correct" to the rule.
2014-12-10core: unify how we iterate over inotify eventsLennart Poettering
Let's add some syntactic sugar for iterating through inotify events, and use it everywhere.
2014-12-03udevd: don't take reference for NULL rtnl objectTom Gundersen
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
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.
2014-11-28udevd: don't set receive buffer size when socket activatedTom Gundersen
The socket unit does this, so no need to redo it in udevd.
2014-11-28treewide: drop unnecessary trailing \n in log_*() callsMichal Schmidt
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().

2014-11-05udev: avoid magic constants in kernel-cmdline parsersDavid Herrmann
Lets recognize the fact that startswith() returns a pointer to the tail on success. Use it instead of hard-coding string-lengths as magic constants.

2014-09-18udev: fix typosTom Gundersen
Spotted by Andreas Henriksson.
2014-09-18udevd: check return of various functionsTom Gundersen
One reported by Coverity. Fixes CID #996252.
2014-09-18udevd: parse_argv - warn if argumens are invalidTom Gundersen
Found by Coverity. Fixes CID #1238780.
2014-09-16udevd: use safe_ato*() in place of strto*()Tom Gundersen
2014-09-16udev: apply permissions to static nodes before signallying READYTom Gundersen
Processes expecting static nodes to have the right permissions may order themselves after systemd-udevd.service, make sure that actually guarantees what is expected.
2014-09-16udev: only print after final log level has been determinedTom Gundersen
This delays label_init(), and drops the (duplicate) printing of version information.
2014-09-16udevd: initialize epoll_event structs on allocationTom Gundersen
Also move the rest of event initialization next to the event loop (no functional change).
2014-09-16udev: don't close std{in,out,err}Tom Gundersen
Rather than printing debug output to stderr and redirecting this to /dev/null when not wanted, use the correct log_*() function in the first place.
2014-09-16udev: drop duplicate loggingTom Gundersen
Once upon a time logging during early boot was unreliable, so extra logging messages were sent by udev to stderr. That is no longer a concern, so drop all fprintf() calls from udved.
2014-09-16udev: split out parse_argv()Tom Gundersen
Also rename some global variables to arg_* to make it clearer where they come from.
2014-09-16udev: split out help and modernise a bitTom Gundersen
2014-09-11udev: timeout - warn after a third of the timeout before killingTom Gundersen
2014-09-10udev: timeout - increase timeoutTom Gundersen
Some kernel modules still take more than one minute to insmod, we no longer rely on the timeout killing insmod within a given period of time, so just bump this to a much higher value. Its only purpose is to make sure that nothing stays aronud forever.
2014-09-09udev - drop print_kmsgTom Gundersen
The only remaining user was 'starting version XXX', which is now logged using log_info().
2014-09-09udev: event - keep one rtnl per worker, rather than per eventTom Gundersen
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.

2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird

2014-07-29udev: unify event timeout handlingKay Sievers
2014-07-29udevd: add --event-timeout commandline optionHannes Reinecke
Some events take longer than the default 30 seconds. Killing those events will leave the machine halfway configured. Add a commandline option '--event-timeout' to handle these cases.
2014-07-24udev: exclude MD from block device ownership event lockingKay Sievers
MD instantiates devices at open(). This is incomptible with the locking logic, as the "change" event emitted when stopping a device will bring it back.
