2013-03-31ModernizationZbigniew Jędrzejewski-Szmek
Use _cleanup_ and wrap lines to ~80 chars and such.
2013-03-31bus: parse matches locally and allow registration of callbacks for themLennart Poettering
This includes code to parse and split up match strings which will also be useful to calculate bloom filter masks when the time comes.
2013-03-30bus: implement server mode, and anonymous authenticationLennart Poettering
2013-03-29Always use errno > 0 to help gccZbigniew Jędrzejewski-Szmek
gcc thinks that errno might be negative, and functions could return something positive on error (-errno). Should not matter in practice, but makes an -O4 build much quieter.
2013-03-28catalog: open up catalog internalsZbigniew Jędrzejewski-Szmek
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.
2013-03-27shared: free dt (temporary dir name) on failVáclav Pavlín
[zj: modified to not to try to rmdir() dir we haven't created.]
2013-03-26Simplify the meaning of %sZbigniew Jędrzejewski-Szmek
The rules governing %s where just too complicated. First of all, looking at $SHELL is dangerous. For systemd --system, it usually wouldn't be set. But it could be set if the admin first started a debug shell, let's say /sbin/sash, and then launched systemd from it. This shouldn't influence how daemons are started later on, so is better ignored. Similar reasoning holds for session mode. Some shells set $SHELL, while other set it only when it wasn't set previously (e.g. zsh). This results in fragility that is better avoided by ignoring $SHELL totally. With $SHELL out of the way, simplify things by saying that %s==/bin/sh for root, and the configured shell otherwise. get_shell() is the only caller, so it can be inlined. Fixes one issue seen with 'make check'.
2013-03-25bus: implement support for FD passingLennart Poettering
2013-03-22util: workaround two gcc warningsZbigniew Jędrzejewski-Szmek
gcc does not know that errno cannot be negative, and warns about unitialized variables later on. Kill the warnings by returning -errno only after checking that errno is positive.
2013-03-22util: be more picky when validating hostnamesLennart Poettering
No longer allow dots at the beginning or end of host names, Or double dots. https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1152187/comments/14
2013-03-22journalctl: give a nice hint about group membership based on ACLs of ↵Lennart Poettering
/var/log/journal If we notice that we unprivileged and not in any of the groups which have access to /var/log/journal, print a nice message about which groups do. This checks and prints all groups that are in the default ACL for /var/log/journal, which is not necessarily correct for all journal files, but pretty close.

2013-03-20Make PrivateTmp dirs also inaccessible from the outsideZbigniew Jędrzejewski-Szmek
Currently, PrivateTmp=yes means that the service cannot see the /tmp shared by rest of the system and is isolated from other services using PrivateTmp, but users can access and modify /tmp as seen by the service. Move the private /tmp and /var/tmp directories into a 0077-mode directory. This way unpriviledged users on the system cannot see (or modify) /tmp as seen by the service.
2013-03-15core: reuse the same /tmp, /var/tmp and inaccessible dirMichal Sekletar
All Execs within the service, will get mounted the same /tmp and /var/tmp directories, if service is configured with PrivateTmp=yes. Temporary directories are cleaned up by service itself in addition to systemd-tmpfiles. Directory which is mounted as inaccessible is created at runtime in /run/systemd.
2013-03-08util: fix printing of welcome messageMichal Schmidt
Commit 984a2be4 failed to adjust this caller of status_printf().

2013-03-05util: properly escape corner cases in bus_path_escape(), tooLennart Poettering
This follows the suggestions from: http://lists.freedesktop.org/archives/systemd-devel/2013-March/009363.html
2013-02-28util: split resolving of /dev/console into a new functionMichal Schmidt
2013-02-28util, core: add support for ephemeral status linesMichal Schmidt
Ephemeral status lines do not end with a newline and they expect to be overwritten by the next printed status line.
2013-02-14bootchart: use conf-parser & CamelCase names in .confThomas Hindoe Paaboel Andersen
2013-02-14honor SELinux labels, when creating and writing config filesHarald Hoyer
Also split out some fileio functions to fileio.c and provide a SELinux aware pendant in fileio-label.c see https://bugzilla.redhat.com/show_bug.cgi?id=881577
2013-02-13efi: efi_get_boot_options() should already sort the entries, the random ↵Lennart Poettering
order in the efivars fs is probably not useful This also introduces a new FOREACH_DIRENT macro and makes use of it.
2013-02-13Revert "log_error() if inotify_add_watch() fails"Lennart Poettering
This reverts commit 2826d14091e43ed3397d862dee79d09d0115c84e. We never should generate log messages from a library.
2013-02-13log_error() if inotify_add_watch() failsHarald Hoyer
[zj: Reworded message s/to watch/to add watch on/ to make it clear that it was the watch init action that failed, and not the "process of watching". I think this way it'll be clearer to people who don't know what inotify does.]
2013-02-13util: *DO NOT* loop for EINTR handling with close_nointr()Colin Walters
See the linked references for why we should not do this.

2013-02-13use strneq instead of strncmpThomas Hindoe Paaboel Andersen
2013-02-11binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services ↵Lennart Poettering
that work on .d/ directories This unifies much of the logic behind them: - All four will now ofllow the rule that the earlier file and earlier assignment in the .d/ directories wins. Before, sysctl was the only outlier, where the later setting always won. - All four now support getopt() and --help on the command line. - All four can now handle specification of configuration file names on the command line to apply. The tools will automatically find them, and apply them. Previously only tmpfiles could do that. This is useful for %post scripts in RPMs and suchlike. - This fixes various error path issues in conf_files_list()
2013-02-11util: rework load_env_file()Lennart Poettering
Inner library calls should not invoke log_oom(), that's something for main programs, not library calls. Don't read through uninitialized memory if a file ends in a continuation line. Add comments for the non-obvious bits. Don't choke on comment lines that are continuation lines. Simplify some things.
2013-02-11util: introduce FOREACH_LINE for iterating through filesLennart Poettering
2013-02-11env: considerably beef up environment cleaning logicLennart Poettering
Now, actually check if the environment variable names and values used are valid, before accepting them. With this in place are at some places more rigid than POSIX, and less rigid at others. For example, this code allows lower-case environment variables (which POSIX suggests not to use), but it will not allow non-UTF8 variable values. All in all this should be a good middle ground of what to allow and what not to allow as environment variables. (This also splits out all environment related calls into env-util.[ch])

2013-01-18util: continuation support for load_env_fileMichal Vyskocil
Variable definitions can be written on more than one line - if each ends with a backslash, then is concatenated with a previous one. Only backslash and unix end of line (\n) are treated as a continuation. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=58083 [zj: squashed two patches together; cleaned up grammar; removed comment about ignoring trailing backslash -- it is not ignored.] Document continuation support in systemd.exec
2013-01-18systemctl: add new "get-cgroup-attr" to query current cgroup attribute valueLennart Poettering
Also adds a pair of bus calls for this to the daemon.
2013-01-17systemctl add command list-dependenciesLukas Nykryn
systemctl list-dependencies lists all unit's dependecies and recursively expands all subsidiary target units into a tree. Primary purpose for this command is to show all units which are enabled in specified target.
2013-01-17util: fix bad memory accessLennart Poettering
2013-01-16systemctl,loginctl,cgls: do not ellipsize cgroup members when --full is ↵Lukas Nykryn
specified New file output.h with output flags and modes. --full parameter also for cgls and loginctl. Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup, show_cgroup_and_extra, show_cgroup_and_extra_by_spec). get_process_cmdline with max_length == 0 will not ellipsize output. Replace LINE_MAX with 0 in some calls of get_process_cmdline. [zj: Default to --full when under pager for clgs. Drop '-f' since it wasn't documented and didn't actually work. Reindent a bit. ]
