tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

udev: add emacs header line Otherwise emacs wants to use 2-space indentation and other attrocities.

tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easy 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.

util-lib: split out allocation calls into alloc-util.[ch]

util-lib: move a number of fs operations into fs-util.[ch]

util-lib: move more file I/O related calls into fileio.[ch]

util-lib: split our string related calls from util.[ch] into its own file 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.

Revert "hwdb: actually search /run/udev/hwdb.d"

hwdb: actually search /run/udev/hwdb.d The documentation claims hwdb entries may be placed in the volatile /run/udev/hwdb.d directory but nothing actually looked at it.

remove unused includes 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.

Assorted format fixes Types used for pids and uids in various interfaces are unpredictable. Too bad.

systemd-hwdb: introduce new tool This pulls out the hwdb managment from udevadm into an independent tool. The old code is left in place for backwards compatibility, and easy of testing, but all documentation is dropped to encourage use of the new tool instead.

udevadm: port to sd-hwdb

libudev: make libudev-hwdb a wrapper around sd-hwdb

udevadm hwdb: discard extra leading whitespaces in hwdb Currently a property in the form of FOO=bar is stored as " FOO=bar", i.e. the property name contains a leading space. That's quite hard to spot. This patch discards all extra whitespaces but the first one which is required by libudev's hwdb_add_property. [zj: modify the check a bit] https://bugs.freedesktop.org/show_bug.cgi?id=82311

treewide: no need to negate errno for log_*_errno() It corrrectly handles both positive and negative errno values.

treewide: auto-convert the simple cases to log_*_errno() 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().

udev hwdb: Support shipping pre-compiled database in system images 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.

udevadm: hwdb - check return value of fseeko() Fonud by Coverity. Fixes CID #996255.

udev: make sure we always return a valid error code in trie_store()

everywhere: make use of new0() and macro() macros, and stop using perror()

Update some message formats Use PID_FMT/USEC_FMT/... in more places. Also update logind error messages to print the full path to a file that failed. This should make debugging easier for people who do not know off the top of their head where logind stores it state.

log: log_error() and friends add a newline after each line anyway, so avoid including it in the log strings

udevadm,scsi_id: add short options to help strings and to the man page Also clean things up a bit here and there.

Fix write-only use of a few variables Since the invention of read-only memory, write-only memory has been considered deprecated. Where appropriate, either make use of the value, or avoid writing it, to make it clear that it is not used.

udev: fix two trivial memleaks in error path Based-on-a-patch-by: Ian Stakenvicius <axs@gentoo.org>

hwdb: allow list of lookup keys per given record This allows to specify: dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Model 231*:pvr* dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Series 12*:pvr* KEY_A=value KEY_B=value Instead of: dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Model 231*:pvr* KEY_A=value KEY_B=value dmi:bvn*:bvr*:bd*:svnVENDOR:pn:Series 12*:pvr* KEY_A=value KEY_B=value

hwdb: remove support for (not fully implemented) conditional properties

move _cleanup_ attribute in front of the type http://lists.freedesktop.org/archives/systemd-devel/2013-April/010510.html

udevadm: do not free node on success A fix for ff03aed06a422.

udevadm-hwdb: avoid leak in error path

catalog: open up catalog internals In order to write tests for the catalog functions, they are made non-static and start taking a 'database' parameter, which is the name of a file with the preprocessed catalog entries. This makes it possible to make test-catalog part of the normal test suite, since it now only operates on files in /tmp. Some more tests are added.

udev: udevadm hwdb - add --root= https://bugs.freedesktop.org/show_bug.cgi?id=60398

udev: remove HWDB_BIN

hwdb: fix usage --create is not a valid option.

hwdb: use $(localstatedir)/lib/udev/hwdb.bin for the binary database It's not configuration, so it doesn't belong in udev. Also, remove the catalog when uninstalling udev.

use the same email address everywhere
