2014-11-24smack: introduce new SmackProcessLabel optionWaLyong Cho
In service file, if the file has some of special SMACK label in ExecStart= and systemd has no permission for the special SMACK label then permission error will occurred. To resolve this, systemd should be able to set its SMACK label to something accessible of ExecStart=. So introduce new SmackProcessLabel. If label is specified with SmackProcessLabel= then the child systemd will set its label to that. To successfully execute the ExecStart=, accessible label should be specified with SmackProcessLabel=. Additionally, by SMACK policy, if the file in ExecStart= has no SMACK64EXEC then the executed process will have given label by SmackProcessLabel=. But if the file has SMACK64EXEC then the SMACK64EXEC label will be overridden. [zj: reword man page]
2014-11-22Do not check for existence of remote binariesZbigniew Jędrzejewski-Szmek
systemd-run would fail when run with -M or -H and an absolute path, if this path did not exists locally. Allow it to continue, since we don't have a nice way of checking if the binary exists remotely. The case where -M or -H is used and a local path is unchanged, and we still iterate over $PATH to find the binary. We need to convert to an absolute path, and we don't have a nice mechanism to check remotely, so we assume that the binary will be located in the same place locally and remotely. http://lists.freedesktop.org/archives/systemd-devel/2014-November/025418.html
2014-11-22missing: add IFLA_BRPORT_LEARNING and friendsZbigniew Jędrzejewski-Szmek
IFLA_BRPORT_LEARNING was added in v3.10-rc4-583-g9ba18891f7, and IFLA_BRPORT_UNICAST_FLOOD in v3.10-rc4-584-g867a59436f.
2014-11-22missing: add __NR_getrandom for a few more archsZbigniew Jędrzejewski-Szmek
Mips has getrandom() too, but there's just too many variants for me too care. Either someone who cares does it, or they get compile-time warnings with old kernel headers.

2014-11-13sd-bus: sync with kdbus upstream (ABI break)Daniel Mack
kdbus has seen a larger update than expected lately, most notably with kdbusfs, a file system to expose the kdbus control files: * Each time a file system of this type is mounted, a new kdbus domain is created. * The layout inside each mount point is the same as before, except that domains are not hierarchically nested anymore. * Domains are therefore also unnamed now. * Unmounting a kdbusfs will automatically also detroy the associated domain. * Hence, the action of creating a kdbus domain is now as privileged as mounting a filesystem. * This way, we can get around creating dev nodes for everything, which is last but not least something that is not limited by 20-bit minor numbers. The kdbus specific bits in nspawn have all been dropped now, as nspawn can rely on the container OS to set up its own kdbus domain, simply by mounting a new instance. A new set of mounts has been added to mount things *after* the kernel modules have been loaded. For now, only kdbus is in this set, which is invoked with mount_setup_late().
2014-11-10strv: rework strv_split_quoted() to use unquote_first_word()Lennart Poettering
This should make the unquoting scheme a bit less naive.

2014-11-10shared/install: when unit contains only Also=, report 'indirect'Jan Synacek
If a unit contains only Also=, with no Alias= or WantedBy=, it shouldn't be reported as static. New 'indirect' status shall be introduced. https://bugzilla.redhat.com/show_bug.cgi?id=864298

After all, this is about files, not arguments, hence EFBIG is more appropriate than E2BIG

2014-11-06switch-root: explain why we don't care about base_filesystem_create() failingLennart Poettering
2014-11-06shared: create files even if the SELinux policy has no context for themMichal Schmidt
The SELinux policy defines no context for some files. E.g.: $ matchpathcon /run/lock/subsys /dev/mqueue /run/lock/subsys <<none>> /dev/mqueue <<none>> We still need to be able to create them. In this case selabel_lookup_raw() returns ENOENT. We should then skip setfscreatecon(), but still return success. It was broken since c34255bdb2 ("label: unify code to make directories, symlinks").
2014-11-06switch_root: do not fail, if base_filesystem_create() failedHarald Hoyer
Not all switch roots are like base_filesystem_create() wants them to look like. They might even boot, if they are RO and don't have the FS layout. Just ignore the error and switch_root nevertheless. base_filesystem_create() should have logged, what went wrong.

Now that we only have one file with condition implementations around, we can drop the -util suffix and simplify things a bit.

2014-11-05core: introduce new Delegate=yes/no property controlling creation of cgroup ↵Lennart Poettering
subhierarchies For priviliged units this resource control property ensures that the processes have all controllers systemd manages enabled. For unpriviliged services (those with User= set) this ensures that access rights to the service cgroup is granted to the user in question, to create further subgroups. Note that this only applies to the name=systemd hierarchy though, as access to other controllers is not safe for unpriviliged processes. Delegate=yes should be set for container scopes where a systemd instance inside the container shall manage the hierarchies below its own cgroup and have access to all controllers. Delegate=yes should also be set for user@.service, so that systemd --user can run, controlling its own cgroup tree. This commit changes machined, systemd-nspawn@.service and user@.service to set this boolean, in order to ensure that container management will just work, and the user systemd instance can run fine.

Explicitly ignore return value of ioctl to set window size. Fixes CID#1250804 and CID#1250800.

Let's be strict here, since its better to be safe than sorry.
2014-11-04barrier: explicitly ignore return values of barrier_place()David Herrmann
The barrier implementation tracks remote states internally. There is no need to check the return value of any barrier_*() function if the caller is not interested in the result. The barrier helpers only return the state of the remote side, which is usually not interesting as later calls to barrier_sync() will catch this, anyway. Shut up coverity by explicitly ignoring return values of barrier_place() if we're not interested in it.
2014-11-04util: introduce negative_errno()David Herrmann
Imagine a constructor like this: int object_new(void **out) { void *my_object; int r; ... r = ioctl(...); if (r < 0) return -errno; ... *out = my_object; return 0; } We have a lot of those in systemd. If you now call those, gcc might inline the call and optimize it. However, gcc cannot know that "errno" is negative if "r" is. Therefore, a caller like this will produce warnings: r = object_new(&obj); if (r < 0) return r; obj->xyz = "foobar"; In case the ioctl in the constructor fails, gcc might assume "errno" is 0 and thus the error-handling is not triggered. Therefore, "obj" is uninitialized, but accessed. Gcc will warn about that. The new negative_errno() helper can be used to mitigate those warnings. The helper is guaranteed to return a negative integer. Furthermore, it spills out runtime warnings if "errno" is non-negative. Instead of returning "-errno", you can use: return negative_errno(); gcc will no longer assume that this can return >=0, thus, it will not warn about it. Use this new helper in libsystemd-terminal to fix some grdev-drm warnings.
