* core: rework serializationLennart Poettering2018-10-261-4/+0
| | | | | | | | | | | | | | | | | Let's be more careful with what we serialize: let's ensure we never serialize strings that are longer than LONG_LINE_MAX, so that we know we can read them back with read_line(…, LONG_LINE_MAX, …) safely. In order to implement this all serialization functions are move to serialize.[ch], and internally will do line size checks. We'd rather skip a serialization line (with a loud warning) than write an overly long line out. Of course, this is just a second level protection, after all the data we serialize shouldn't be this long in the first place. While we are at it also clean up logging: while serializing make sure to always log about errors immediately. Also, (void)ify all calls we don't expect errors in (or catch errors as part of the general fflush_and_check() at the end.
* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-4/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

* timedatectl: stop using xstrftimeZbigniew Jędrzejewski-Szmek2017-10-181-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | When using strftime in arbitrary locales, we cannot really say how big the buffer should be. Let's make the buffer "large", which will work fine pretty much always, and just print n/a if the timestamp does not fit. strftime returns 0 if the buffer is too small and a NUL-terminated string otherwise, so we can drop the size specifications in string formatting. $ export LANG=fa_IR.UTF-8 $ date چهارشنبه ۱۸ اكتبر ۱۷، ساعت ۱۰:۵۴:۲۴ (+0330) $ timedatectl Assertion 'xstrftime: a[] must be big enough' failed at ../src/timedate/timedatectl.c:105, function print_status_info().

* Parse "timeout=0" as infinity in various generators (#6264)Zbigniew Jędrzejewski-Szmek2017-07-031-0/+1
| | | | | | | | | | | | This extends 2d79a0bbb9f651656384a0a86ed814e6306fb5dd to the kernel command line parsing. The parsing is changed a bit to only understand "0" as infinity. If units are specified, parse normally, e.g. "0s" is just 0. This makes it possible to provide a zero timeout if necessary. Simple test is added. Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1462378.
* time-util: add new call usec_shift_clock() for converting times between clocksLennart Poettering2017-06-221-0/+2
| | | | We use that quite often, let's implement one clean version of it.
* time-util: rename usec_sub() to usec_sub_signed() and add usec_sub_unsigned()Lennart Poettering2017-06-221-5/+9
| | | | | Quite often we just want to subtract two normal usec_t values, hence provide an implementation for that.
* time-util: refuse formatting/parsing times that we can't storeLennart Poettering2017-02-021-0/+11
| | | | | | | | | | | usec_t is always 64bit, which means it can cover quite a number of years. However, 4 digit year display and glibc limitations around time_t limit what we can actually parse and format. Let's make this explicit, so that we never end up formatting dates we can#t parse and vice versa. Note that this is really just about formatting/parsing. Internal calculations with times outside of the formattable range are not affected.

* util-lib: make timestamp generation and parsing reversible (#3869)Lennart Poettering2016-08-031-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves parsing and generation of timestamps and calendar specifications in two ways: - The week day is now always printed in the abbreviated English form, instead of the locale's setting. This makes sure we can always parse the week day again, even if the locale is changed. Given that we don't follow locale settings for printing timestamps in any other way either (for example, we always use 24h syntax in order to make uniform parsing possible), it only makes sense to also stick to a generic, non-localized form for the timestamp, too. - When parsing a timestamp, the local timezone (in its DST or non-DST name) may be specified, in addition to "UTC". Other timezones are still not supported however (not because we wouldn't want to, but mostly because libc offers no nice API for that). In itself this brings no new features, however it ensures that any locally formatted timestamp's timezone is also parsable again. These two changes ensure that the output of format_timestamp() may always be passed to parse_timestamp() and results in the original input. The related flavours for usec/UTC also work accordingly. Calendar specifications are extended in a similar way. The man page is updated accordingly, in particular this removes the claim that timestamps systemd prints wouldn't be parsable by systemd. They are now. The man page previously showed invalid timestamps as examples. This has been removed, as the man page shouldn't be a unit test, where such negative examples would be useful. The man page also no longer mentions the names of internal functions, such as format_timestamp_us() or UNIX error codes such as EINVAL.
* time-util: add triple timestamp objectLennart Poettering2016-06-061-1/+26
| | | | | | | | | | | | We already have a double timestamp object that we use whenever we need both a MONOTONIC and a REALTIME timestamp taken and stored. With this change we also add a triple timestamp object that in addition stores a BOOTTIME timestamp, which is useful for a few usecases. Note that we keep dual_timestamp around, as it is useful in many cases where triple_timestamp is not, in particular because retrieving the monotonic and realtime timestamps is much cheaper on Linux that getting the boottime timestamp.
* tree-wide: don't assume CLOCK_BOOTIME is generally availableLennart Poettering2016-04-221-0/+1
| | | | | | | | | | | | Before we invoke now(CLOCK_BOOTTIME), let's make sure we actually have that clock, since now() will otherwise hit an assert. Specifically, let's refuse CLOCK_BOOTTIME early in sd-event if the kernel doesn't actually support it. This is a follow-up for #3037, and specifically: https://github.com/systemd/systemd/pull/3037#issuecomment-210199167
* time-util: Rename and fix call of deserialize_timestamp_value()Benjamin Robin2016-02-151-1/+1
| | | | | | The deserialize_timestamp_value() is renamed timestamp_deserialize() to be more consistent with dual_timestamp_deserialize() And add the NULL check back on realtime and monotonic
* time-util: introduce deserialize_timestamp_value()Alexander Kuleshov2016-02-161-0/+1
| | | | | | | | | | | | | The time-util.c provides dual_timestamp_deserialize() function to convert value to usec_t and set it as value of ts->monotonic and ts->realtime. There are some places in code which do the same but only for one clockid_t (realtime or monotonic), when dual_timestamp_deserialize() sets value of both. This patch introduces the deserialize_timestamp_value() which converts a given value to usec_t and write it to a given timestamp.

* basic: nicer xsprintf and xstrftime assert messagesMichal Schmidt2015-09-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | It's nicer if the assertion failure message from a bad use of xsprintf actually mentions xsprintf instead of the expression the macro is implemented as. The assert_message_se macro was added in the previous commit as an internal helper, but it can also be used for customizing assertion failure messages like in this case. Example: char buf[10]; xsprintf(buf, "This is a %s message.\n", "long"); Before: Assertion '(size_t) snprintf(buf, ELEMENTSOF(buf), "This is a %s message.\n", "long") < ELEMENTSOF(buf)' failed at foo.c:6, function main(). Aborting. After: Assertion 'xsprintf: buf[] must be big enough' failed at foo.c:6, function main(). Aborting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation of the unified cgroup support, let's clean up cgtop: a) rework time code to be based on "nsec_t" rather than "struct timespec" b) Introduce long option --order= for selecting ordering c) count number of processes only in the main hierarchy, don't bother with the controller hierarchies. We don't allow orthogonal hierarchies in systemd anymore, hence there's no point to check the other hierarchies. d) Deal with non-monotonic cpuacct values (see #749) e) When sorting groups, don't do prefix compare when ordering by number of tasks, since this is not accumulative for all children. f) Actually make --cpu without parameter work g) Don't output control characters when we get them as input. Fixes #749.

| | | | | | | | | | | | | | Some of the operations machined/machinectl implement are also very useful when applied to the host system (such as machinectl login, machinectl shell or machinectl status), hence introduce a pseudo-machine by the name of ".host" in machined that refers to the host system, and may be used top execute operations on the host system with. This copies the pseudo-image ".host" machined already implements for image related commands. (This commit also adds a PK privilege for opening a PTY in a container, which was previously not accessible for non-root.)
