a5bd3c32ab sd_pid_notify_with_fds: fix computing msg_controllen
CMSG_SPACE(0) may return value other than 0. This caused sendmsg to fail
with EINVAL, when have_pid or n_fds was 0.

Wrong smack label of the symlink in CGROUP root directory when enabling '--with-smack-run-label' (v3)

bcce71873b core: freeze execution if /etc/mtab exists
The mount monitor that was added to libmount v2.27 requires /etc/mtab to be
non-existant. As systemd now uses that functionality, we cannot monitor any
mounts anymore, and hence not support .mount units.

Systems that have /etc/mtab around as regular file are unsupported by
systemd since a long time.

This patch makes that condition fatal, so we do not boot up with
non-working mount monitor support.

f8c1a81c51 smack: bugfix the smack label of symlink when '--with-smack-run-label' is set
Even though systemd has its own smack label since
'--with-smack-run-label' configuration is set, the smack label of each
CGROUP root directory should have the star (i.e. *) label. This is
mainly because current Linux Kernel set the label in this way.
(Refer to smack_d_instantiate() in security/smack/smack_lsm.c)

However, if systemd has its own smack label and arg_join_controllers is
explicitly set or initialized by initialize_join_controllers() function,
current systemd creates the symlink in CGROUP root directory with its
own smack label as below.

lrwxrwxrwx. 1 root root System  11 Dec 31 16:00 cpu -> cpu,cpuacct
dr-xr-xr-x. 4 root root *        0 Dec 31 16:01 cpu,cpuacct
lrwxrwxrwx. 1 root root System  11 Dec 31 16:00 cpuacct -> cpu,cpuacct

This patch fixes that bug by copying the smack label from the origin.

ba056b738d smack: introduce new mac_smack_copy() function
This adds a new mac_smack_copy() function in order to read the smack
label from the source and apply it to the destination.

158df4b6a6 gpt-auto: fix ESP options and description
Since 59512f21 the parameters were passed in the wrong order, causing the
options to be interpreted as the description.

Also, while "false" was supposed to be passed for "rw", the ESP should actually
be mounted read-write. It just happened to be "true" since the description char*
was passed for "rw".

4610de5022 inspawn: switch from SOCK_DGRAM to SOCK_SEQPACKET for internal socketpairs
SOCK_DGRAM and SOCK_SEQPACKET have very similar semantics when used with
socketpair(). However, SOCK_SEQPACKET has the advantage of knowing a
hangup concept, since it is inherently connection-oriented.

Since we use socket pairs to communicate between the nspawn main process
and the nspawn child process, where the child might die abnormally it's
interesting to us to learn about this via hangups if the child side of
the pair is closed. Hence, let's switch to SOCK_SEQPACKET for these
internal communication sockets.

Fixes #956.
