GLIB has recently started to officially support the gcc cleanup
attribute in its public API, hence let's do the same for our APIs.
With this patch we'll define an xyz_unrefp() call for each public
xyz_unref() call, to make it easy to use inside a
__attribute__((cleanup())) expression. Then, all code is ported over to
make use of this.
The new calls are also documented in the man pages, with examples how to
use them (well, I only added docs where the _unref() call itself already
had docs, and the examples, only cover sd_bus_unrefp() and
sd_event_unrefp()).
This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we
tend to call our destructors these days.
Note that this defines no public macro that wraps gcc's attribute and
makes it easier to use. While I think it's our duty in the library to
make our stuff easy to use, I figure it's not our duty to make gcc's own
features easy to use on its own. Most likely, client code which wants to
make use of this should define its own:
#define _cleanup_(function) __attribute__((cleanup(function)))
Or similar, to make the gcc feature easier to use.
Making this logic public has the benefit that we can remove three header
files whose only purpose was to define these functions internally.
See #2008.

There are more than enough to deserve their own .c file, hence move them
over.

string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

Turns this:
r = -errno;
log_error_errno(errno, "foo");
into this:
r = log_error_errno(errno, "foo");
and this:
r = log_error_errno(errno, "foo");
return r;
into this:
return log_error_errno(errno, "foo");

Replace this:
if (fd >= 0)
safe_close(fd);
by this:
safe_close(fd);
|
|
Replace this:
close(fd);
fd = -1;
write this:
fd = safe_close(fd);

Push the extraction of the envp + argv as close as possible to their use, to avoid code
duplication. As a sideeffect fix logging when delaing execution.

This fixes CID#1304688.

udevd: event - don't log about failures of spawn processes when this …
|
|
|
|
PROGRAM and IMPORT{program} uses the exit code of the spawn process to decide if a rule matches or not,
a failing process is hence normal operation and not something we should warn about.
We still warn about other types of failing processes.
|
|
|
|
We used to block all signals, and restore the original signal mask before exec'ing
external processes.
Now we just block the signals we care about and unconditionally unblock all signals
before exec'ing.
|
|
Mostly for documentation purposes.
|
|
No functional changes.
|
|
This allows us to drop the special sigterm handling in spawn_wait()
as this will now be passed directly to the worker event loop.
We now log failing spawend processes at 'warning' level, and timeouts
are in terms of CLOCK_BOOTTIME when available, otherwise the behavior
is unchanged.

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.
|
|
|
|
Instead introduce ensure_usec_initialized(), which copies the timestamp if possible otherwise
sets it to now(CLOCK_MONOTONIC).
|
|
This allows us to move the db reading from udevd to libudev.
|
|
We were explicitly eagerly loading the db, then deletenig the backing file and then processing the
rules/symlinks. Instead we delete the backnig db file as the last step and let the db loading be
lazy as everywhere else.
This may save us a bit of work in casese where the db is not needed, but more importantly it hides
some implementation details of libudev-device form udevd.
|
|
To copy properties from one device to another. Drop the equivalent functionality from udevd.
|
|
This should have been committed with
udev_device_add_property - implicitly mark properties for saving to db
|
|
|
|
This should be internal to the library as it is only about reflecting the sysfs state in the udev_device.
|
|
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.
|
|
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.
|
|
Stay uniform and use 'dev' rather than 'event->dev', as these are aliases (and event->dev looks
like it may be a typo for event->dev_db).
|
|
|
|
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.
|
|
Types used for pids and uids in various interfaces are unpredictable.
Too bad.
|
|
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.
|
|
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.

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.

This fixes CID #1237641.

As of 3.17, the kernel will do this on its own, so just do regular log_debug() logging from udev.
|
|
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.
