From a931ad47a8623163a29d898224d8a8c1177ffdaf Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 5 Nov 2014 17:57:23 +0100 Subject: core: introduce new Delegate=yes/no property controlling creation of cgroup 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. --- src/machine/machined-dbus.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/machine') diff --git a/src/machine/machined-dbus.c b/src/machine/machined-dbus.c index 3c7d4be8d2..7f8c631ef6 100644 --- a/src/machine/machined-dbus.c +++ b/src/machine/machined-dbus.c @@ -622,6 +622,10 @@ int manager_start_scope( if (r < 0) return r; + r = sd_bus_message_append(m, "(sv)", "Delegate", "b", 1); + if (r < 0) + return r; + if (more_properties) { r = sd_bus_message_copy(m, more_properties, true); if (r < 0) -- cgit v1.2.3-54-g00ecf
