sd_notify is not synchronous, iow. it only waits until the message
reaches the queue not until it is processed by systemd
when the process that sent such a message exits before systemd could
process it, it cannot be associated to the correct pid
so in case of reloading, we send a message with 'MAINPID=<newpid>'
to signal that it will change. if now the old process exits before
systemd knows this, it will not accept the 'READY=1' message from the
child, since it rejects the MAINPID change
since there is no (AFAICS) library interface to check the unit status,
we use 'systemctl is-active <SERVICE_NAME>' to check the state until
it is not 'reloading' anymore.
on newer systemd versions, there is 'sd_notify_barrier' which would
allow us to wait for systemd to have all messages from the current
pid to be processed before acknowledging to the child, but on buster
the systemd version is to old...

writing to a file can explode quite easily.
time formatting to rfc3339 should be more robust, but it has a few
conditions where it could fail, so catch that too (and only really
do it if required).
The writes to stdout are left as is, it normally is redirected to
journal which is in memory, and thus breaks later than most stuff,
and at that point we probably do not care anymore anyway.

We renamed the last one always to a file without compression
extension, even if it was .zst previously. So always add the correct
ending to the new last one, if compress was true.
Further, we cannot detect if there'd be a compression required if we
rotated (renamed) it already to the file with .zst included.
So check on rotation itself if it would be a "no .zst" -> ",zst"
transition, and call compress there.

we never actually compressed any files, since we only looked at
the extension:
* if it was 'zst' (which was always true for newly rotated files), we
would not compress it
* even if it was not 'zst', we compressed it inplace, never adding '.zst'
(possibly compressing them multiple times as zstd)
now we add new rotated files simply as '.X' and add a 'target' to the
compress fn, where we rename it to (but now we have to unlink the source
path)

The first rotation is normally the one still opened by one or more
processes for writing, so it must NOT be replaced, removed, ..., as
this then makes the remaining logging, until those processes are
noticed that they should reopen the logfile due to rotation, goes
into nirvana, which is far from ideal for a log.
Only rotating (renaming) is OK for this active file, as this does not
invalidates the file and keeps open FDs intact.
So start compressing with the second rotation, which should be clear
to use, as all writers must have been told to reopen the log during
the last rotation, reopen is a fast operation and normally triggered
at least day ago (at least if one did not dropped the state file
manually), so we are fine to archive that one for real.
If we plan to allow faster rotation the whole rotation+reopen should
be locked, so that we can guarantee that all writers switched over,
but this is unlikely to be needed.
Again, this is was logrotate sanely does by default since forever.

this is not the job of logrotate, and the real 20+ years battle
tested log rotate binary does not do so either as it's actually
pretty dangerous.
If we "replace" the file we break any logger which already opened a
new one here, e.g., a dameon starting up, and thus that writer would
log to nirvana.
It's the job of a logger to create a file if not existing, it makes
no sense to do it here.

If a fuse_loop instance dies suddenly (e.g. SIGKILL), the FUSE mount and
loop device assignment are left behind. We can determine this scenario
on specific unmap, when the PID file is either missing or contains a PID
of a non-running process, but the backing file and potentially loop
device are still there.
If that's the case, do an "emergency cleanup", by unassigning the
loopdev, calling 'fusermount -u' and then cleaning any leftover files
manually.
With this in place, pretty much any situation is now recoverable via
only the 'proxmox-backup-client' binary, by either calling 'unmap' with
or without parameters.

On unmap, only report success if the instance we are killing actually

A 'map' call will only clean up what it needs, that is only leftover
files or dangling instances of it's own name.
For a full cleanup the user can call 'unmap' without any arguments.
The 'cleanup on error' behaviour of map_loop is removed. It is no longer
needed (since the next call will clean up anyway), and in fact fixes a
bug where trying to map an image twice would result in an error, but
also cleanup the .pid file of the running instance, causing 'unmap' to
fail afterwards.

So user doesn't need to remember which loop devices he has mapped to
what.
systemd unit encoding is used to transform a unique identifier for the
mapped image into a suitable name. The files created in /run/pbs-loopdev
will be named accordingly.
The encoding all happens outside fuse_loop.rs, so the fuse_loop module
does not need to care about encodings - it can always assume a name is a
valid filename.
'unmap' without parameter displays all current mappings. It's
autocompletion handler will list the names of all currently mapped
images for easy selection. Unmap by /dev/loopX or loopdev number is
maintained, as those can be distinguished from mapping names.
Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
Allows mapping fixed-index .img files (usually from VM backups) to be
mapped to a local loopback device.
The architecture uses a FUSE-backed temp file mapped to a loopdev:
/dev/loopX -> FUSE /run/pbs-loopdev/xxx -> backup client -> PBS
Since unmapping requires some cleanup (unmap the loopdev, stop FUSE,
remove the temp files) a special 'unmap' command is added, which uses a
PID file to send SIGINT to the backup-client instance started with
'map', which will handle the cleanup itself.
The polling with select! in mount.rs needs to be split in two, since we
have a chicken and egg problem between running FUSE and setting up the
loop device - so we need to do them concurrently, until the loopdev is
assigned, at which point we can report success and daemonize, and then
continue polling the FUSE loop future.
A loopdev module is added to tools containing all required functions for
mapping a loop device to the FUSE file, with the ioctls moved into an
inline module to avoid exposing them directly.
The client code is placed in the 'mount' module, which, while
admittedly a loose fit, allows reuse of the daemonizing code.
