2015-03-01shared: introduce cmsg_close_all() callLennart Poettering
The call iterates through cmsg list and closes all fds passed via SCM_RIGHTS. This patch also ensures the call is used wherever appropriate, where we might get spurious fds sent and we should better close them, then leave them lying around. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-02-11udev: event - move renaming of udev_device to libudevTom Gundersen
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. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2015-02-08util: rework strappenda(), and rename it strjoina()Lennart Poettering
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. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2015-01-25src/shared/util.{c,h}: fix build when mkostemp is not supportedPeter Seiderer
Not all instance of mkostemp were protected with #ifndef HAVE_DECL_MKOSTEMP. We fix this for the definition of the wrapper mkostemp_safe() in the c file and in the header. Signed-off-by: Peter Seiderer <ps.report@gmx.net> Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-12-29util: 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. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-12-20util: rename ignore_file() to hidden_file()Lennart Poettering
hidden_file() is a bit more precise, since dot files usually shouldn't be ignored, but certainly be considered hidden. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-12-20util: when using basename() for creating temporary files, verify the ↵Lennart Poettering
resulting name is actually valid Also, rename filename_is_safe() to filename_is_valid(), since it actually does a full validation for what the kernel will accept as file name, it's not just a heuristic.

2014-12-11core: unify how we iterate over inotify eventsLennart Poettering
Let's add some syntactic sugar for iterating through inotify events, and use it everywhere. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>
2014-11-28util: add function getting proc environJakub Filak
On the contrary of env, the added function returns all characters cescaped, because it improves reproducibility. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

2014-10-31hashmap: rewrite the implementationMichal Schmidt
We reintroduce hashmap.{h,c}, list.h and set.h verbatim from upstream, before we punt dead code. The following is the upstream message: This is a rewrite of the hashmap implementation. Its advantage is lower memory usage. It uses open addressing (entries are stored in an array, as opposed to linked lists). Hash collisions are resolved with linear probing and Robin Hood displacement policy. See the references in hashmap.c. Some fun empirical findings about hashmap usage in systemd on my laptop: - 98 % of allocated hashmaps are Sets. - Sets contain 78 % of all entries, plain Hashmaps 17 %, and OrderedHashmaps 5 %. - 60 % of allocated hashmaps contain only 1 entry. - 90 % of allocated hashmaps contain 5 or fewer entries. - 75 % of all entries are in hashmaps that use trivial_hash_ops. Clearly it makes sense to: - store entries in distinct entry types. Especially for Sets - their entries are the most numerous and they require the least information to store an entry. - have a way to store small numbers of entries directly in the hashmap structs, and only allocate the usual entry arrays when the direct storage is full. The implementation has an optional debugging feature (enabled by defining the ENABLE_HASHMAP_DEBUG macro), where it: - tracks all allocated hashmaps in a linked list so that one can easily find them in gdb, - tracks which function/line allocated a given hashmap, and - checks for invalid mixing of hashmap iteration and modification. Since entries are not allocated one-by-one anymore, mempools are not used for entries. Originally I meant to drop mempools entirely, but it's still worth it to use them for the hashmap structs. My testing indicates that it makes loading of units about 5 % faster (a test with 10000 units where more than 200000 hashmaps are allocated - pure malloc: 449±4 ms, mempools: 427±7 ms). Here are some memory usage numbers, taken on my laptop with a more or less normal Fedora setup after booting with SELinux disabled (SELinux increases systemd's memory usage significantly): systemd (PID 1) Original New Change dirty memory (from pmap -x 1) [KiB] 2152 1264 -41 % total heap allocations (from gdb-heap) [KiB] 1623 756 -53 % Signed-off-by: Anthony G.

2014-08-22util: change return value of startswith() to non-consteudev/v1.10Lennart Poettering
This way we can use it on non-const strings, and don't end up with a const'ified result. This is similar to libc's strstr() which also takes a const string but returns a non-const one. Signed-off-by: Anthony G. Basile <blueness@gentoo.org>

The structure of the source tree is basically correct and this is about as far as we can go without hacking at the C code.
2012-11-15Isolation of udev code from remaining systemdAnthony G. Basile
This commit is a first attempt to isolate the udev code from the remaining code base. It intentionally does not modify any files but purely delete files which, on a first examination, appear to not be needed. This is a sweeping commit which may easily have missed needed code. Files can be retrieved by doing a checkout from the previous commit: git checkout 2944f347d0 -- <filename>

2012-11-02util : fallback to plain ASCII drawing if locale is not UTF-8Michal Schmidt
When printing cgroup and sysfs hierarchies, avoid using UTF-8 box drawing characters if the locale is not UTF-8. https://bugzilla.redhat.com/show_bug.cgi?id=871153
2012-11-02util: add is_locale_utf8()Michal Schmidt
journalctl and vconsole-setup both implement utf8 locale detection. Let's have a common function for it. The next patch will add another use.
2012-10-30shared: "max" in the string->number conversion is meant to be inclusiveMichal Schmidt
2012-10-30shared, core: do not always accept numbers in string lookupsMichal Schmidt
The behaviour of the common name##_from_string conversion is surprising. It accepts not only the strings from name##_table but also any number that falls within the range of the table. The order of items in most of our tables is an internal affair. It should not be visible to the user. I know of a case where the surprising numeric conversion leads to a crash. We will allow the direct numeric conversion only for the tables where the mapping of strings to numeric values has an external meaning. This holds for the following lookup tables: - netlink_family, ioprio_class, ip_tos, sched_policy - their numeric values are stable as they are defined by the Linux kernel interface. - log_level, log_facility_unshifted - the well-known syslog interface. We allow the user to use numeric values whose string names systemd does not know. For instance, the user may want to test a new kernel featuring a scheduling policy that did not exist when his systemd version was released. A slightly unpleasant effect of this is that the name##_to_string conversion cannot return pointers to constant strings anymore. The strings have to be allocated on demand and freed by the caller.
