2013-10-29path_check_timestamp: only keep the most recent timestampTom Gundersen
There is no point in keeping one timestamp for each directory, as we only ever care about the most recent one.
2013-10-29udev: link-config - add proper parsingTom Gundersen
2013-10-29conf-parser: add macro for ENUMVTom Gundersen
Parses a whitespace separated list of strings into a vector of enums.
2013-10-28udev: link-config - move naming policy from udev rulesTom Gundersen
This introduces a new key NamePolicy, which takes an ordered list of naming policies. The first successful one is applide. If all fail the value of Name (if any) is used. The possible policies are 'onboard', 'slot', 'path' and 'mac'. This patch introduces a default link file, which replaces the equivalent udev rule.

2013-10-26STRV_FOREACH_BACKWARDS: improve readability a bitTom Gundersen
The indentation was wrong, also put the semicolon on a separate line to make it clear it is a for-loop with an epmyt body.
2013-10-26udev: move udev_rules_check_timestamp to sharedTom Gundersen
I want to use this from a bulitin in a subsequent patch.
2013-10-26STRV_FOREACH_BACWARDS: start at the tail of the listTom Gundersen
Otherwise, the user would have to manually initialize the pointer. Nobody currently uses this code, so the change in behaviour sohuld be fine.

2013-10-20log: avoid calling the logging functions for log levels above the current ↵Kay Sievers
maximum Messages with log levels above the current maximum log level will be dropped inside log_meta(). But to be able to call the function, all parameters for the function need to be provided. This can easily get expensive, if values need to be calculated or functions are used in parameters. Avoid all useless work by checking inside the macro, before we look at any parameters passed to the logging functions.
2013-10-19kerne-command-line: introduce option 'systemd.restore_state'Tom Gundersen
When set to 0 this will stop tools like the backlight and rfkill tools to restore state from previous boot. This is useful in case the stored state is bogus to the extent that it is preventing you from resetting it (e.g., the backlight settings cause the screen to be off on boot on a system where the backlight can not be adjusted directly from the keyboard).
2013-10-17timedated: expose time and NTP sync flag via the busLennart Poettering
This way, timedatectl can be run over the network and determine all properties correctly from the server rather than the client.
2013-10-16macro: clean up usage of gcc attributesLennart Poettering
Always use our own macros, and name all our own macros the same style.
2013-10-14Fix bad assert in show_pid_arrayZbigniew Jędrzejewski-Szmek
This function should get the same treatment as other qsort uses did in 7ff7394 "Never call qsort on potentially NULL arrays". Reported-by: Oleksii Shevchuk <alxchk@gmail.com>
2013-10-14shared/util: Fix glob_extend() argumentBastien Nocera
glob_extend() would completely fail to work, or return incorrect data if it wasn't being passed the current getopt "optarg" variable as it used the global variable, instead of the passed parameters.
2013-10-14list: make our list macros a bit easier to use by not requring type spec on ↵Lennart Poettering
each invocation We can determine the list entry type via the typeof() gcc construct, and so we should to make the macros much shorter to use.
2013-10-14util: allow trailing semicolons on define_trivial_cleanup_func linesLennart Poettering
Emacs C indenting really gets confused by these lines if they carry no trailing semicolon, hence let's make this nicer for good old emacs. The other macros which define functions already do this too, so let's copy the scheme here. Also, let's use an uppercase name for the macro. So far our rough rule was that macros that are totally not function-like (like this ones, which define a function) are uppercase. (Well, admittedly it is a rough rule only, for example function and variable decorators are all lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and also they at least got underscore prefixes.) Also, the macros that define functions that we already have are all uppercase, so let's do the same here...

2013-10-13Never call qsort on potentially NULL arraysZbigniew Jędrzejewski-Szmek
This extends 62678ded 'efi: never call qsort on potentially NULL arrays' to all other places where qsort is used and it is not obvious that the count is non-zero.
2013-10-13unicode: treat cute symbol block as fullwidthZbigniew Jędrzejewski-Szmek
UNICODE standards only talk about fullwidth characters for East Asian scripts. But it seems that all those symbols are fullwidth too.
2013-10-13util, utf8: make ellipsize take multi-byte characters into accountShawn Landden
rename old versions to ascii_* Do not take into account zerowidth characters, but do consider double-wide characters. Import needed utf8 helper code from glib. v3: rebase ontop of utf8 restructuring work [zj: tweak the algorithm a bit, move new code to separate file]
2013-10-11smack: minimize ifdef use, and move all labeling to smack-util.cKay Sievers
2013-10-11macro: add new assert_return() macro for early parameter checking in functionsLennart Poettering
For the library functions we expose we currently repeatedly use checks like the following: if (!value_is_ok(parameter1)) return -EINVAL; if (!value_is_ok(parameter2)) return -EINVAL; And so on. Let's turn this into a macro: assert_return(value_is_ok(parameter1), -EINVAL); assert_return(value_is_ok(paramater2), -EINVAL); This makes our code a bit shorter and simpler, and also allows us to add a _unlikely_() around the check.
2013-10-10event: add timer accuracy/coalescing logicLennart Poettering
In order to improve energy consumption we should minimize our wake-ups when handling timers. Hence, for each timer take an accuracy value and schedule the actual wake-up time somewhere between the specified time and the specified timer plus the accuracy. The specified time of timer event sources hence becomes the time the handler is called the *earliest*, and the specified time plus the accuracy the time by which it is called the *latest*, leaving the library the freedom to schedule the wake-up somewhere inbetween. If the accuracy is specified as 0 the default of 250ms will be used. When scheduling timeouts we will now try to elapse them at the same point within each second, across the entire system. We do this by using a fixed perturbation value keyed off the boot id. If this point within a second is not in the acceptable range, we try again with a fixed time within each 250ms time step. If that doesn't work either, we wake up at the last possible time.

2013-10-10security: rework selinux, smack, ima, apparmor detection logicLennart Poettering
Always cache the results, and bypass low-level security calls when the respective subsystem is not enabled.
2013-10-10bus: add minimal event loop APILennart Poettering
So far we tried to use epoll directly wherever we needed an event loop. However, that has various shortcomings, such as the inability to handle larger amounts of timers (since each timerfd costs one fd, which is a very limited resource, usually bounded to 1024), and inability to do priorisation between multiple queued events. Let's add a minimal event loop API around epoll that is suitable for implementation of our own daemons and maybe one day can become public API for those who desire it. This loop is part of libsystemd-bus, but may be used independently of it.

2013-10-09Smack: Test if smack is enabled before mountingAuke Kok
Since on most systems with xattr systemd will compile with Smack support enabled, we still attempt to mount various fs's with Smack-only options. Before mounting any of these Smack-related filesystems with Smack specific mount options, check if Smack is functionally active on the running kernel. If Smack is really enabled in the kernel, all these Smack mounts are now *fatal*, as they should be. We no longer mount smackfs if systemd was compiled without Smack support. This makes it easier to make smackfs mount failures a critical error when Smack is enabled. We no longer mount these filesystems with their Smack specific options inside containers. There these filesystems will be mounted with there non-mount smack options for now.

2013-10-02nspawn: always copy /etc/resolv.conf rather than bind mountLennart Poettering
We were already creating the file if it was missing, and this way containers can reconfigure the file without running into problems. This also makes resolv.conf handling more alike to handling of /etc/localtime, which is also not a bind mount.

Let read()/write() report any error/EOF.
2013-10-01hashmap: size hashmap bucket array dynamicallyLennart Poettering
Instead of fixing the hashmap bucket array to 127 entries dynamically size it, starting with a smaller one of 31. As soon as a fill level of 75% is reached, quadruple the size, and so on. This should siginficantly optimize the lookup time in large tables (from O(n) back to O(1)), and save memory on smaller tables (which most are).
