The parser used for MTU and Speed expects them to be size_t, not unsigned int.
This caused a corruption in the rest of the structure.
Reported by David O Neill <david.m.oneill@intel.com>.

Makes it a bit clearer what is going on, rather than jumping to the end of main().
No functional change.
|

First parse config, then sanitize environment before donig any further setup.
No functional change.

No functional change.

This uses kill_and_sigcont() instead of kill(), otherwise no functional change.
|
|
We were returning rather than continuing in some cases. The intention
was always to fully process all pending events before returning
from the SIGCHLD handler. Restore this behaviour.

This way it is more obvious that the queue flag file is always
up-to-date. Moreover, we only have to touch/unlink it when the
first/last event is allocated/freed.
|
|
EAGAIN means there are no more messages to read, so give up. EINTR means we got interrupted
reading a message, so try again.
|
|
When notifying the main daemon about event completion, make sure the message is sent
successfully, and not interrupted.
|
|
Path, Driver and Type are now strv rather than strings, so free them properly.
|
|
Bring this in line with the rest of the codebase.

|
Stop relying on global variables in event handlers, and move them
all to a Manager object instead.
|
|
|
|
This avoids updating the flag files twice for every loop, and also removes another dependency
in the main-loop, so we are freer to reshufle it as we want.
|
|
Rather than skippling ctrl handling whenever we have handlede inotify events
(and hence may have synthesized a 'change' event), just call the uevent
handling explicitly from on_inotify() so that the event queue is up-to-date.
|
|
|
|
This allows us to simplify the ctrl_msg handler. Eventually all this global state should move to
a Manager object or so.

Simply query the size of the hashmap keeping all the worker contexts instead.
|
|
This makes the code somewhat more readable.
|
|
Make the worker context have the same life-span as the worker process. It is created on fork()
and free'd on SIGCHLD.
The change means that we can get worker_returned() for a worker context that is no longer around,
this is not a problem and we can just drop the message. The only use for worker_returned() is to
know to reschedule events to workers that are still around, so if the worker has already exited
it is not important to keep track of. We still print a debug statement in this case to be on the
safe side.
|
|
Eeeew!
|
|
|
|
Follow the coding style and avoid the exit handlers.
|
|
We never return magic exit codes, but just EXIT_FAILUER or EXIT_SUCCESS.
|
|
|
|
|
|
|
|
Take and drop explicit references where it makes sense.
|
|
This is not used in the worker, so avoid having to free it there.
|
|
|
|
We used to use this to track failed events so they could be retriggered,
but that is no longer done, so the code can be dropped.
|
|
|
|
If the main daemon is not notified about a worker finishing an event
the refcounting of the worker struct will be wrong, and we will lose
track of the number of children we have to wait for.
This should not happen, but if it does we better complain loudly about
it. Worst case udev will wait for 30 seconsd at shutdown waiting for
nonexistent workers.
|
|
|
|
No need to include this explicitly, just use SCM_CREDENTIALS.
|
|
We should not be receiving these anyway, but let's be correct.
|
|
|
|
Remove some redundant logging, and reduce the log-level in most cases. The only
case that is really critical is if a worker failed while hanlding an event, so
keep that at error level.

This reverts b67f944. Lazy loading of device properties does not work for devices
that are received over netlink, as these are sealed. Reinstate the unconditional
loading of the device db.
Reported by: Mantas Mikulėnas <grawity@gmail.com>.
|
|
The old tags are read from the db when deciding which tags to clear,
make sure we don't write out the new db before the old one has been
read.
|
|
When running udevadm settle --timeout=0, the ping always times out, and
udevadm will return 0 without checking the queue state.
(David: Use a reasonable timeout to still get the barrier provided by
ctrl-ping)
|
|
Let's make Coverity happy about this one.

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.
