mount: don't consider activated until /sbin/mount returns
So far, we considered mount units activated as soon as the mount
appeared. This avoided seeing a difference between mounts started by
systemd, and e.g. by running `mount` from a terminal.
(`umount` was not handled this way).
However in some cases, options passed to `mount` require additional
system calls after the mount is successfully created. E.g. the
`private` mount option, or the `ro` option on bind mounts.
It seems best to wait for mount to finish doing that. E.g. in
the `private` case, the current behaviour could theoretically cause
non-deterministic results, as child mounts inherit the
private/shared propagation setting from their parent.
This also avoids a special case in mount_reload().

mount: clarify that umount retries do not (anymore) allow multiple timeouts
It _looks_ as if, back when we used to retry unsuccessful calls to umount,
this would have inflated the effective timeout. Multiplying it by
RETRY_UMOUNT_MAX. Which is set to 32.
I'm surprised if it's true: I would have expected it to be noticed during
the work on NFS timeouts. But I can't see what would have stopped it.
Clarify that I do not expect this to happen anymore. I think each
individual umount call is allowed up to the full timeout, but if umount
ever exited with a signal status, we would stop retrying.
To be extra clear, make sure that we do not retry in the event that umount
perversely returned EXIT_SUCCESS after receiving SIGTERM.
Alan Jenkins [Sat, 20 Jan 2018 20:05:52 +0000 (20:05 +0000)]
mount: mountinfo event is supposed to always arrive before SIGCHLD
"Due to the io event priority logic we can be sure the new mountinfo is
loaded before we process the SIGCHLD for the mount command."
I think this is a reasonable expectation. But if it works, then the
other comment must be false:
"Note that mount(8) returning and the kernel sending us a mount table
change event might happen out-of-order."
Therefore we can clean up the code for the latter.
If this is working as advertised, then we can make sure that mount units
fail if the mount we thought we were creating did not actually appear,
due to races or trickery (or because /sbin/mount did something unexpected
despite returning EXIT_SUCCESS).
Include a specific warning message for this failure.
If we give up when the mount point is still mounted after 32 successful
calls to /sbin/umount, that seems a fairly similar case. So make that
message a LOG_WARN as well (not LOG_DEBUG). Also, this was recently changed to only
retry while umount is returning EXIT_SUCCESS; in that case in particular
there would be no other messages in the log to suggest what had happened.

mount: forbid mount on path with symlinks
It was forbidden to create mount units for a symlink. But the reason is
that the mount unit needs to know the real path that will appear in
/proc/self/mountinfo. The kernel dereferences *all* the symlinks in the
path at mount time (I checked this with `mount -c` running under `strace`).
This will have no effect on most systems. As recommended by docs, most
systems use /etc/fstab, as opposed to native mount unit files.
fstab-generator dereferences symlinks for backwards compatibility.
A relatively minor issue regarding Time Of Check / Time Of Use also exists
here. I can't see how to get rid of it entirely. If we pass an absolute
path to mount, the racing process can replace it with a symlink. If we
chdir() to the mount point and pass ".", the racing process can move the
directory. The latter might potentially be nicer, except that it breaks
WorkingDirectory=.
I'm not saying the race is relevant to security - I just want to consider
how bad the effect is. Currently, it can make the mount unit active (and
hence the job return success), despite there never being a matching entry
in /proc/self/mountinfo. This wart will be removed in the next commit;
i.e. it will make the mount unit fail instead.

core: namespace: remove unnecessary mode on /dev/shm mount target
This should have no behavioural effect; it just confused me.
All the other mount directories in this function are created as 0755.
Some of the mounts are allowed to fail - mqueue and hugepages.
If the /dev/mqueue mount target was created with the permissive mode 01777,
to match the filesystem we're trying to mount there, then a mount failure
would allow unprivileged users to write to the /dev filesystem, e.g. to
exhaust the available space. There is no reason to allow this.
(Allowing the user read access (0755) seems a reasonable idea though, e.g. for
quicker troubleshooting.)
We do not allow failure of the /dev/shm mount, so it doesn't matter that
it is created as 01777. But on the same grounds, we have no *reason* to
create it as any specific mode. 0755 is equally fine.
This function will be clearer by using 0755 throughout, to avoid
unintentionally implying some connection between the mode of the mount
target, and the mode of the mounted filesystem.

add false option for tests (#7778)
Currently there is no way to prevent tests from building using meson.
This introduces two problems:
1) It adds a extra 381 files to compile.
2) One of these tests explicitly requires libgcrypt to be built even if systemd
is not using it.
3) It adds C++ to the requirements to build systemd.
When cross-compiling, this is uneccessary.

core: prevent spurious retries of umount
Testing the previous commit with `systemctl stop tmp.mount` logged the
reason for failure as expected, but unexpectedly the message was repeated
32 times.
The retry is a special case for umount; it is only supposed to cover the
case where the umount command was _successful_, but there was still some
remaining mount(s) underneath. Fix it by making sure to test the first
condition :).
Re-tested with and without a preceding `mount --bind /mnt /tmp`,
and using `findmnt` to check the end result.

zsh/coredumpctl: Never sort the completion candidates
That way, they're always sorted by date. I do not know how to make ZSH sort

zsh/coredumpctl: Fix the completion
An output from coredumpctl list is like
> TIME PID UID GID SIG COREFILE EXE
> Sun 2016-05-29 18:44:03 CEST 14578 1000 1000 6 none /tmp/pacaurtmp-wieland/python33/src/Python-3.3.6/python
^1 ^2 ^3 ^4 ^5
, but the previous sub() command turns that into
> TIMEPID UID GID SIG COREFILE EXE
> Sun2016-05-29 18:44:03 CEST 14578 1000 1000 6 none /tmp/pacaurtmp-wieland/python33/src/Python-3.3.6/python
^1 ^2 ^3 ^4 ^5
so the whole pipeline generated entries like
$UID:$DESCRIPTION
but that's not useful and probably not what was supposed to happen.
This now generates entries like
$PID:$DESCRIPTION
which make everything work.
Note that with this commmit, the completions will be sorted by PID by
ZSH.

core: fix output (logging) for mount units (#7603)
Documentation - systemd.exec - strongly implies mount units get logging.
It is safe for mounts to depend on systemd-journald.socket. There is no
cyclic dependency generated. This is because the root, -.mount, was
already deliberately set to EXEC_OUTPUT_NULL. See comment in
mount_load_root_mount(). And /run is excluded from being a mount unit.
Nor does systemd-journald depend on /var. It starts earlier, initially
logging to /run.
Tested before/after using `systemctl stop tmp.mount`.

process-util: make our freeze() routine do something useful
When we crash we freeze() our-self (or possibly we reboot the machine if
that is configured). However, calling pause() is very unhelpful thing to
do. We should at least continue to do what init systems being doing
since 70's and that is reaping zombies. Otherwise zombies start to
accumulate on the system which is a very bad thing. As that can prevent
admin from taking manual steps to reboot the machine in somewhat
graceful manner (e.g. manually stopping services, unmounting data
volumes and calling reboot -f).
