For two releases those exported with version 183 by mistake, and then
they were fixed to have version 215 (015419c0df libudev: fix symbol
version for udev_queue_flush() and udev_queue_get_fd()). But that
breaks ABI compatibility for binaries compiled with udev from before
that commit. There most likely very few such binaries, if any, but as
a matter of principle we should export the old symbols too, in order
to keep full compatibility.

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.

This reverts commit d6d810fbf8071f8510450dbacd1d083f37603656.
It's apparently not OK to pass MSG_CMSG_CLOEXEC to recvmsg() of raw
sockets.

|
|
|
After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.
|
|
|
|
Hide the details a bit.

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.
|
|
|
|
Don't use recvmsg(2) return value to check for too long packets
(it doesn't work) but MSG_TRUNC flag.

Lets not pollute the global namespace. Prefix all our exported names and
macros with SD_HWDB_*.

Using the same scripts as in f647962d64e "treewide: yet more log_*_errno
+ return simplifications".
|
|
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.

When used in an initramfs, it's expected that the hwdb.bin file is
not present (it makes for a very large initramfs otherwise).
While it's nice to tell the user about this, as it's not strictly
speaking an error we really shouldn't be so forceful in our
reporting.

FILE * wants cleanup_fclose().
Spotted by udev hwdb segfaulting in gnome-continuous' buildroot
construction.

The term "priority" is misleading because higher levels have lower
priority. "Level" is clearer and shorter.
This commit touches only the textual descriptions, not function and variable
names themselves. "Priority" is used in various command-line switches and
protocol constants, so completly getting rid of "priority" is hard.
I also left "priority" in various places where the clarity suffered
when it was removed.

Invalid log levels lead to a assert failure later on.

This brings udev logging style a bit closer to normal systemd convention.
|
|
In some cases it is preferable to ship system images with a pre-generated
binary hwdb database, to avoid having to build it at runtime, avoid shipping
the source hwdb files, or avoid storing large binary files in /etc.
So if hwdb.bin does not exist in /etc/udev/, fall back to looking for it in
UDEVLIBEXECDIR. This keeps the possibility to add files to /etc/udev/hwdb.d/
and re-generating the database which trumps the one in /usr/lib.
Add a new --usr flag to "udevadm hwdb --update" which puts the database
into UDEVLIBEXECDIR.
Adjust systemd-udev-hwdb-update.service to not generate the file in /etc if we
already have it in /usr.
|
|
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.

The function still succeeds, so there is no functional change. This fixes CID #996288.

Use rmdir_parents() from src/shared instead.
|
|
Use shared versions instead. Difference is with overwriting of repeated user/group
name, and lack of logging.

This extends the udev parser to support OP_REMOVE (-=) and adds support
for TAG-= to remove previously set tags. We don't fail if the tag didn't
exist.
This is pretty handy if we ship default rules for seat-assignments and
users want to exclude specific devices from that. They can easily add
rules that drop any automatically added "seat" tags again.
|
|
The only remaining user was 'starting version XXX', which is now logged using log_info().
|
|
Those symbols were introduced in commit
14cb733684d3c3f50d088a3a370ddf8e8894dfa4 and released in v215.

They have different size on 32 bit, so they are really not interchangable.

No functional change expected :)

We have a bunch of reports from people who have a custom kernel and
are confused why udev is not running. Issue a warning on
error. Barring an error in the code, the only error that is possible
is ENOSYS.
