2015-05-20util: introduce reset_uid_gid() for resetting all uids and gids to 0Lennart Poettering
2015-05-20core,nspawn: unify code that moves the root dirLennart Poettering
2015-05-19bootctl: modernizationZbigniew Jędrzejewski-Szmek
Use strjoina to avoid error handling, and openat to simplify things. Some fixes on the way: - ferror does not set errno, so the return value was wrong in some cases - errors are propagated in more cases - EFI/systemd was created, but EFI/systemd-boot was deleted - something is always printed on error - when checking the version, comparison was done against "systemd-bo" for some reason - return value was converted from negative to EXIT_SUCCESS/EXIT_FAILURE twice, resulting in EXIT_SUCCESS all the time

2015-05-19shared/json: Added DOM-like JSON parserPavel Odvody
This makes working with complexly structured documents easy and more reliable as the parser is not susceptible to element re-ordering. Also fixes a bug when the tokenizer would choke after reading a number.

2015-05-19hostname: Allow comments in /etc/hostnameMartin Pitt
The hostname(1) tool allows comments in /etc/hostname. Introduce a new read_hostname_config() in hostname-util which reads a hostname configuration file like /etc/hostname, strips out comments, whitespace, and cleans the hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code. Update hostname manpage. Add tests. https://launchpad.net/bugs/1053048
2015-05-19core: introduce seperate reverse dependencies for Requires= and Requisite=Lennart Poettering
This allows us to ensure that Requisite= dependencies never cause propagation between units, while Requires= dependencies might. http://lists.freedesktop.org/archives/systemd-devel/2015-May/031742.html
2015-05-19journalctl: clean up how we log errorsLennart Poettering
All functions should either log the errors they run into, or only return them in which case the caller should log them. Make sure this rule is followed, so that each error is logged precisely once, and neither never, nor more than once.

2015-05-18fstab-generator: add x-systemd.requires and x-systemd.requires-mounts-forKarel Zak
Currently we have no way how to specify dependencies between fstab entries (or another units) in the /etc/fstab. It means that users are forced to bypass fstab and write .mount units manually. The patch introduces new systemd fstab options: x-systemd.requires=<PATH> - to specify dependence an another mount (PATH is translated to unit name) x-systemd.requires=<UNIT> - to specify dependence on arbitrary UNIT x-systemd.requires-mounts-for=<PATH ...> - to specify dependence on another paths, implemented by RequiresMountsFor=. The option may be specified more than once. For example two bind mounts where B depends on A: /mnt/test/A /mnt/test/A none bind,defaults /mnt/test/A /mnt/test/B none bind,x-systemd.requires=/mnt/test/A More complex example with overlay FS where one mount point depends on "low" and "upper" directories: /dev/sdc1 /mnt/low ext4 defaults /dev/sdc2 /mnt/high ext4 defaults overlay /mnt/merged overlay lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high https://bugzilla.redhat.com/show_bug.cgi?id=812826 https://bugzilla.redhat.com/show_bug.cgi?id=1164334
2015-05-16util: loop_write - accept 0-length messageTom Gundersen
write() can send empty messages, so make sure loop_write() can do the same.
2015-05-15socket-util: socket_address_parse() should not log errors on its ownLennart Poettering
Given that socket_address_parse() is mostly a "library" call it shouldn't log on its own, but leave that to its caller. This patch removes logging from the call in case IPv6 is not available but and IPv6 address shall be parsed. Instead a new call socket_address_parse_and_warn() is introduced which first invokes socket_address_parse() and then logs if necessary. This should fix "make check" on ipv6-less kernels: http://lists.freedesktop.org/archives/systemd-devel/2015-April/031385.html

2015-05-14util: introduce memmem_safe() and make use of itLennart Poettering
GNU memmem() requires a nonnull first parameter. Let's introduce memmem_safe() that removes this restriction for zero-length parameters, and make use of it where appropriate. http://lists.freedesktop.org/archives/systemd-devel/2015-May/031705.html
2015-05-14util: use GNU comparison function prototype for qsort_safe()Lennart Poettering
2015-05-13util: add generic calls for prefixing a root directory to a pathLennart Poettering
So far a number of utilities implemented their own calls for this, unify them in prefix_root() and prefix_roota(). The former uses heap memory, the latter allocates from the stack via alloca(). Port over most users of a --root= logic.
2015-05-13nspawn: skip symlink to a combined cgroup hierarchy if it already existsIago López Galeiras
If a symlink to a combined cgroup hierarchy already exists and points to the right path, skip it. This avoids an error when the cgroups are set manually before calling nspawn.
2015-05-13shared: Use O_EXCL with O_TMPFILE in open_tmpfileCristian Rodríguez
In this usecase, the file will never be materialized with linkat().
2015-05-12udevd: make udev_ctrl_connection globalTom Gundersen
This allows us to simplify the ctrl_msg handler. Eventually all this global state should move to a Manager object or so.
2015-05-11install: when exporting prefix InstallInfo to become UnitFileInstallInfoLennart Poettering
All other types exported from install.h should be namespaces like this, hence namespace InstallInfo the same way. Also, remove external forward definition of UnitFileScope type.
2015-05-11core: rename SystemdRunningAs to ManagerRunningAsLennart Poettering
It's primarily just a property of the Manager object after all, and we try to refer to PID 1 as "manager" instead of "systemd", hence let's to stick to this here too.
2015-05-11core,network: major per-object logging reworkLennart Poettering
This changes log_unit_info() (and friends) to take a real Unit* object insted of just a unit name as parameter. The call will now prefix all logged messages with the unit name, thus allowing the unit name to be dropped from the various passed romat strings, simplifying invocations drastically, and unifying log output across messages. Also, UNIT= vs. USER_UNIT= is now derived from the Manager object attached to the Unit object, instead of getpid(). This has the benefit of correcting the field for --test runs. Also contains a couple of other logging improvements: - Drops a couple of strerror() invocations in favour of using %m. - Not only .mount units now warn if a symlinks exist for the mount point already, .automount units do that too, now. - A few invocations of log_struct() that didn't actually pass any additional structured data have been replaced by simpler invocations of log_unit_info() and friends. - For structured data a new LOG_UNIT_MESSAGE() macro has been added, that works like LOG_MESSAGE() but prefixes the message with the unit name. Similar, there's now LOG_LINK_MESSAGE() and LOG_NETDEV_MESSAGE(). - For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(), LOG_NETDEV_INTERFACE() macros have been added that generate the necessary per object fields. The old log_unit_struct() call has been removed in favour of these new macros used in raw log_struct() invocations. In addition to removing one more function call this allows generated structured log messages that contain two object fields, as necessary for example for network interfaces that are joined into another network interface, and whose messages shall be indexed by both. - The LOG_ERRNO() macro has been removed, in favour of log_struct_errno(). The latter has the benefit of ensuring that %m in format strings is properly resolved to the specified error number. - A number of logging messages have been converted to use log_unit_info() instead of log_info() - The client code in sysv-generator no longer #includes core code from src/core/. - log_unit_full_errno() has been removed, log_unit_full() instead takes an errno now, too. - log_unit_info(), log_link_info(), log_netdev_info() and friends, now avoid double evaluation of their parameters
2015-05-11util: optimize free_and_strdup() if NOPLennart Poettering
Under the assumption that strcmp() is cheaper than memory allocation, let's avoid the allocation, if the new value is identical to the old.

2015-05-10Generate systemd-fsck-root.service in the initramfsZbigniew Jędrzejewski-Szmek
In the initrafms, generate a systemd-fsck-root.service to replace systemd-fsck@<sysroot-device>.service. This way, after we transition to the real root, systemd-fsck-root.service is marked as already done. This introduces an unnecessary synchronization point, because systemd-fsck@* is ordered after systemd-fsck-root also in the initramfs. In practice this shouldn't be a problem. https://bugzilla.redhat.com/show_bug.cgi?id=1201979 C.f. 956eaf2b8d6c9999024705ddadc7393bc707de02.

2015-05-05core: rework unit name validation and manipulation logicLennart Poettering
A variety of changes: - Make sure all our calls distuingish OOM from other errors if OOM is not the only error possible. - Be much stricter when parsing escaped paths, do not accept trailing or leading escaped slashes. - Change unit validation to take a bit mask for allowing plain names, instance names or template names or an combination thereof. - Refuse manipulating invalid unit name
2015-05-05util: be a bit safer in path_is_safe()Lennart Poettering
We should be more strict when verifying paths with path_is_safe() for potentially dangerous constructs, and that includes lengths of PATH_MAX-1 and larger. Be more accurate here.

2015-05-04generators: rename add_{root,usr}_mount to add_{sysroot,sysroot_usr}_mountZbigniew Jędrzejewski-Szmek
This makes it obvious that those functions are only usable in the initramfs. Also, add a warning when noauto, nofail, or automount is used for the root fs, instead of silently ignoring. Using those options would be a sign of significant misconfiguration, and if we bother to check for them, than let's go all the way and complain. Other various small cleanups and reformattings elsewhere.

2015-04-30core: rework cgroup path parse logicLennart Poettering
Various cleanups, be stricter when parsing unit paths. Most importantly: return the root slice "-.slice" when asked for slice of paths that contain no slice component.
2015-04-29sd-bus: properly handle creds that are known but undefined for a processLennart Poettering
A number of fields do not apply to all processes, including: there a processes without a controlling tty, without parent process, without service, user services or session. To distuingish these cases from the case where we simply don't have the data, always return ENXIO for them, while returning ENODATA for the case where we really lack the information. Also update the credentials dumping code to show this properly. Fields that are known but do not apply are now shown as "n/a". Note that this also changes some of the calls in process-util.c and cgroup-util.c to return ENXIO for these cases.

2015-04-23util: Fix assertion in split() on missing 'Martin Pitt
When parsing a unit with a trailing slash after an escaped line break, like ExecStart=/bin/echo 'foo \ bar' the split() function (through config_parse()) asserted and crashed pid 1: Assertion 'current[*l + 1] == quotechars[0]' failed at ../src/shared/util.c:583, function split(). Aborting. Fix this by returning an error in this case ("trailing garbage"). Add corresponding test case. Also fix the missing "unit" argument of config_parse_exec() in the comment. https://launchpad.net/bugs/1447243
