2014-10-08systemctl: add add-wants and add-requires verbsLukas Nykryn
2014-10-07core: don't allow enabling if unit is maskedJan Synacek
2014-10-02Rename user_runtime to user_runtime_dirZbigniew Jędrzejewski-Szmek
This makes this function name similar to user_config_home() and makes it match the name of the environment variable.
2014-10-02add a transient user unit directorySteven Allen
This patch adds a transient user unit directory under `$XDG_RUNTIME_DIR/systemd/user/` and stores transient user-instance units (such as those created by `systemd-run --user`) under there instead of putting them in $XDG_CONFIG_HOME/systemd/user/. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=67331
2014-09-16shared: fix resource leak in config_parse_default_instanceAndreas Henriksson
The recently allocated "printed" is not freed on error path. Found by coverity. Fixes: CID#1237745
2014-09-15hashmap: introduce hash_ops to make struct Hashmap smallerMichal Schmidt
It is redundant to store 'hash' and 'compare' function pointers in struct Hashmap separately. The functions always comprise a pair. Store a single pointer to struct hash_ops instead. systemd keeps hundreds of hashmaps, so this saves a little bit of memory.
2014-08-27systemctl: fix broken list-unit-files with --rootLukas Nykryn
2014-08-26Revert "systemctl: fix broken list-unit-files with --root"Lennart Poettering
This reverts commit 41a451cc2901a5deb985aea4cc8de204a22e5612. This breaks checks for masking of units file, since we invoke null_or_empty_path() on the resulting path.
2014-08-25systemctl: fix broken list-unit-files with --rootLukas Nykryn
This patch modifies unit_file_get_list which will now return hashmap of structures where f->path is *without* root_dir prefix. This change should be ok, because current code either does not use root_dir at all or calls basename() on the f->path.
2014-08-21install: simplify usage of _cleanup_ macrosLennart Poettering
2014-08-20systemctl: fail in the case that no unit files were foundLukas Nykryn
Previously systemctl died with message -bash-4.2# systemctl --root /rawhi list-unit-files (src/systemctl/systemctl.c:868) Out of memory. in the case that no unit files were found in the --root or the directory did not exist. So lets return ENOENT in the case that --root does not exist and empty list in the case that there are no unit files.
2014-08-13util: allow strappenda to take any number of argsDave Reisner
This makes strappenda3 redundant, so we remove its usage and definition. Add a few tests along the way for sanity.
2014-07-31Properly report invalid quoted stringsZbigniew Jędrzejewski-Szmek
$ systemd-analyze verify trailing-g.service [./trailing-g.service:2] Trailing garbage, ignoring. trailing-g.service lacks ExecStart setting. Refusing. Error: org.freedesktop.systemd1.LoadFailed: Unit trailing-g.service failed to load: Invalid argument. Failed to create trailing-g.service/start: Invalid argument
2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird
2014-07-26Add utility function to append root to pathZbigniew Jędrzejewski-Szmek
2014-07-26Always check asprintf return codeKarel Zak
There is a small number of the places in sources where we don't check asprintf() return code and assume that after error the function returns NULL pointer via the first argument. That's wrong, after error the content of pointer is undefined.
2014-07-16test-tables: add new entriesZbigniew Jędrzejewski-Szmek
One missing string found. A few things had to be moved around to make it possible to test them.
2014-07-16Let config_parse open file where applicableZbigniew Jędrzejewski-Szmek
Special care is needed so that we get an error message if the file failed to parse, but not when it is missing. To avoid duplicating the same error check in every caller, add an additional 'warn' boolean to tell config_parse whether a message should be issued. This makes things both shorter and more robust wrt. to error reporting.
2014-07-15Constify ConfigTableItem tablesZbigniew Jędrzejewski-Szmek
2014-06-20conf-files: include root in returned file pathsMichael Marineau
This restores the original root handling logic that was present prior to 112cfb18 when path expansion moved to path_strv_canonicalize_absolute. That behavior partially went away in 12ed81d9. Alternatively all users of conf_files_list* could be updated to concatenate the paths themselves as unit_file_query_preset did but since no user needs the un-concatenated form that is pointless duplication.

instances
2014-06-17install: introduce new DefaultInstance= field for [Install] sectionsLennart Poettering
The DefaultInstance= name is used when enabling template units when only specifying the template name, but no instance. Add DefaultInstance=tty1 to getty@.service, so that when the template itself is enabled an instance for tty1 is created. This is useful so that we "systemctl preset-all" can work properly, because we can operate on getty@.service after finding it, and the right instance is created.
2014-06-17install: when looking for a unit file for enabling, search for templates ↵Lennart Poettering
only after traversing all search directories Let's always make sure to look in all search directories for the full unit names first, before looking for templates for them.

2014-06-17install: teach preset query logic --root= supportLennart Poettering
2014-06-17install: beef up preset logic to limit to only enable or only disable, and ↵Lennart Poettering
do all-unit preset operations The new "systemctl preset-all" command may now be used to put all installed units back into the enable/disable state the vendor/admin encoded in preset files. Also, introduce "systemctl --preset-mode=enable-only" and "systemctl --preset-mode=disable-only" to only apply the enable or only the disable operations of a "systemctl preset" or "systemctl preset-all" operation. "systemctl preset-all" implements this RFE: https://bugzilla.redhat.com/show_bug.cgi?id=630174

2014-06-13install: fix invalid free() in unit_file_mask()Andreas Henriksson
int unit_file_mask(...) in ./src/shared/install.c calls get_config_path(...) which can in 4 error cases return without setting "ret", and thus "prefix" can be uninitialized when unit_file_mask(...) finishes (which it does directly after the error is returned from get_config_path(...)).
2014-05-15Make systemctl --root look for files in the proper placesZbigniew Jędrzejewski-Szmek
Running systemctl enable/disable/set-default/... with the --root option under strace reveals that it accessed various files and directories in the main fs, and not underneath the specified root. This can lead to correct results only when the layout and configuration in the container are identical, which often is not the case. Fix this by adding the specified root to all file access operations. This patch does not handle some corner cases: symlinks which point outside of the specified root might be interpreted differently than they would be by the kernel if the specified root was the real root. But systemctl does not create such symlinks by itself, and I think this is enough of a corner case not to be worth the additional complexity of reimplementing link chasing in systemd. Also, simplify the code in a few places and remove an hypothetical memory leak on error.
2014-05-15shared/install: do not prefix created symlink with root pathZbigniew Jędrzejewski-Szmek
Before: /var/tmp/inst1//etc/systemd/system/default.target -> /var/tmp/inst1//usr/lib/systemd/system/graphical.target After: /var/tmp/inst1/etc/systemd/system/default.target -> /usr/lib/systemd/system/graphical.target

2014-04-16install: create_symlink() check unlink() return valueDjalal Harouni
create_symlink() do not check the return value of unlink(), this may confuse the user. Before the unlink() call we check the 'force' argument. If it is not set we fail with -EEXIST, otherwise we unlink() the file, therefore the next symlink() should not fail with -EEXIST (do not count races...). However since callers may not have appropriate privileges to unlink() the file we lose the -EPERM or any other errno code of unlink(), and return the -EEXIST of the next symlink(). Fix this by checking unlink() results. Before: $ systemctl --force --root=~/container-03 set-default multi-user.target Failed to set default target: File exists After: $ systemctl --force --root=~/container-03 set-default multi-user.target Failed to set default target: Permission denied
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-02-24Remove dead lines in various placesZbigniew Jędrzejewski-Szmek
As pointed-out by clang -Wunreachable-code. No behaviour changes.

2013-12-25bus: rename message "serial" to "cookie"Lennart Poettering
Even if the lower-leveld dbus1 protocol calls it "serial", let's expose the word "cookie" for this instead, as this is what kdbus uses and since it doesn't imply monotonicity the same way "serial" does.
2013-12-21install: replace readdir_r with readdirFlorian Weimer
The old code incorrectly assumed that readdir_r updates errno.
2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.
2013-11-25conf-parser: distinguish between multiple sections with the same nameTom Gundersen
Pass on the line on which a section was decleared to the parsers, so they can distinguish between multiple sections (if they chose to). Currently no parsers take advantage of this, but a follow-up patch will do that to distinguish [Address] Address=192.168.0.1/24 Label=one [Address] Address=192.168.0.2/24 Label=two from [Address] Address=192.168.0.1/24 Label=one Address=192.168.0.2/24 Label=two
2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.
