2013-08-28Disallow invalid UTF-8 configurationZbigniew Jędrzejewski-Szmek
It is best to catch such errors early. If invalid UTF-8 ends up being given to dbus methods, the program will crash: process 20801: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file dbus-message.c line 2598.
2013-07-26journalctl: use _COMM= match for scriptsZbigniew Jędrzejewski-Szmek
In case of scripts, _EXE is set to the interpreter name, and _COMM is set based on the file name. Add a match for _COMM, and _EXE if the interpreter is not a link (e.g. for yum, the interpreter is /usr/bin/python, but it is a link to /usr/bin/python2, which in turn is a link to /usr/bin/python2.7, at least on Fedora, so we end up with _EXE=/usr/bin/python2.7). I don't think that such link chasing makes sense, because the final _EXE name is more likely to change.
2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).
2013-05-06fileio: split write_one_line_file into twoZbigniew Jędrzejewski-Szmek
The new function allows one to write to an already open file.

2013-04-18fileio.c: do not parse comments after non-whitespace charsHarald Hoyer
systemd does not want to understand comments after the first non-whitespace char occured. key=foo #comment will result into key == "foo #comment" key="foo" #comment will result into key == "foo#comment" "key= #comment" will result into key == "#comment" "key #comment" is an invalid line

2013-04-17core/execute: report invalid environment variables from filesHarald Hoyer
Because "export key=val" is not supported by systemd, an error is logged where the invalid assignment is coming from. Introduce strv_env_clean_log() to log invalid environment assignments, where logging is possible and allowed. parse_env_file_internal() is modified to allow WHITESPACE in keys, to report the issues later on.
2013-04-17fileio:parse_env_file_internal() fix environment file parsingHarald Hoyer
parse_env_file_internal() could not parse the following lines correctly: export key="val" key="val"#comment
2013-04-17fileio: also escape $ and ` when writing out env varsMantas Mikulėnas
These are also considered special by sh and bash.
2013-04-03fileio: don't check for errors more often than really necessaryLennart Poettering
2013-04-03fileio: write proper env var write-out codeLennart Poettering
This will properly escape all weird chars when writing env var files. With this in place we can now read and write environment files where the values contain arbitrary weird chars. This enables hostnamed and suchlike to finally properly save pretty host names with backlashes or quotes in them.
2013-04-03shared: rework env file readerLennart Poettering
Implement this with a proper state machine, so that newlines and escaped chars can appear in string assignments. This should bring the parser much closer to shell.
2013-04-03util: rename write_one_line_file() to write_string_file()Lennart Poettering
You can write much more than just one line with this call (and we frequently do), so let's correct the naming.
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.

2013-02-14honor 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
