The conf_files_list family accepts an alternate root path to prefix all
directories in the list but path_strv_canonicalize_uniq doesn't use it.
This results in the suspicious behavior of resolving directory symlinks
based on the contents of / instead of the alternate root.
This adds a prefix argument to path_strv_canonicalize which will now
prepend the prefix, if given, to every path in the list. To avoid
answering what a relative path means when called with a root prefix
path_strv_canonicalize is now path_strv_canonicalize_absolute and only
considers absolute paths. Fortunately all users of already call
path_strv_canonicalize with a list of absolute paths.
Currently if the user logs out, the GC may never call user_stop(),
this will not terminate the systemd user and (sd-pam) of that user.
To fix this, remove the USER_CLOSING state check that is blocking the
GC from calling user_stop(). Since if user_check_gc() returns false
this means that all the sessions of the user were removed which will
make user_get_state() return USER_CLOSING.
Conclusion: that test will never be statisfied.
So we remove the USER_CLOSING check and replace it with a check inside
user_stop() this way we know that user_stop() has already queued stop
jobs, no need to redo.
This ensures that the GC will get its two steps correctly as pointed out
by Lennart:

Note: this also fixes another bug that prevents creating the user
private dbus socket which will break communications with the user
manager.
The kernel still doesn't support audit in containers, so let's make use
of seccomp and simply turn it off entirely. We can get rid of this big
as soon as the kernel is fixed again.
So far we followed the rule to always indicate the "flavour" of
constructors after the "_new_" or "_open_" in the function name, so
let's keep things in sync here for rtnl and do the same.
The "sd_" prefix is supposed to be used on exported symbols only, and
not in the middle of names. Let's drop it from the cleanup macros hence,
to make things simpler.
The bus cleanup macros don't carry the "sd_" either, so this brings the
APIs a bit nearer.
This is useful to prohibit execution of non-native processes on systems,
for example 32bit binaries on 64bit systems, this lowering the attack
service on incorrect syscall and ioctl 32→64bit mappings.
- Allow configuration of an errno error to return from blacklisted
syscalls, instead of immediately terminating a process.
- Fix parsing logic when libseccomp support is turned off
- Only keep the actual syscall set in the ExecContext, and generate the
string version only on demand.
Udev does not run in containers, so instead of relying on it to tell us when a
network device is ready to be used by networkd, we simply assume that any
device was fully initialized before being added to the container.
This allows customization of the arguments used by less. The main
motivation is that some folks might not like having --no-init on every
invocation of less.
Let's remove the tests for cg_path_get_machine_name(), since they no
longer operate solely on the cgroup path, but actually look up data in
/run. Since we have a test for cg_pid_get_machine_name() this shouldn't
be too much of a loss.
Otherwise we get a (harmless) message like:
systemd-logind[30845]: Failed to process message [type=signal sender=:1.36 path=/org/freedesktop/systemd1/job/4674 interface=org.freedesktop.DBus.Properties member=PropertiesChanged signature=sa{sv}as]: Invalid argument
In function user_get_state() remove the session_is_active() check, just
count on the session_get_state() function to get the correct session
state.
session_is_active() may return true before starting the session scope
and user service, this means it will return true even before the creation
of the session fifo_fd which will produce incorrect states.
So be consistent and just use session_get_state().
Also limit the range of vlan ids. Other implementations and
documentation use the ranges {0,1}-{4094,4095}, but we use
the one accepted by the kernel: 0-4094.
