Dominik Csapak 264779e704 server/worker_task: simplify task log writing
instead of prerotating 1000 tasks
(which resulted in 2 writes each time an active worker was finished)
simply append finished tasks to the archive (which will be rotated)

page cache should be good enough so that we can get the task logs fast

since existing installations might have an 'index' file, we
still have to read tasks from there, but only if it exists

this simplifies the TaskListInfoIterator a good amount

by moving the properties of the storage status out again to the top

also introduce proper structs for the types used, to get type-safety

this changes the backup counts from an array of [groups,snapshots] to
an object/struct with { groups, snapshots } and include 'other' types
(though we do not have any at this moment)

this way it is better documented

this also adapts the ui code to cope with the api changes

Dominik Csapak 5499bd3dee fix #2998: encode mtime as i64 instead of u64
saves files mtime as i64 instead of u64 which enables backup of
files with negative mtime

the catalog_decode_i64 is compatible to encoded u64 values (if < 2^63)
but not reverse, so all "old" catalogs can be read with the new
decoder, but catalogs that contain negative mtimes will decode wrongly
on older clients

also remove the arbitrary maximum value of 2^63 - 1 for
encode_u64 (we just use up to 10 bytes now) and correctly
decode them and update the comments accordingly

adds also test for i64 encode/decode and for compatibility between
u64 encode and i64 decode

Dominik Csapak 8b4f4d9ee4 tools/logrotate: fix compression logic
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)

Thomas Lamprecht b4b14dc16e do_verification_job: fix "never-reverify" and refactor/comment
commit a4915dfc2b made a wrong fix, as
it did not observed that the last expressions was done under the
invariant that we had a last verification result, because if none
could be loaded we already returned true (include).

It thus broke the case for "never re-verify", which is important when
using multiple schedules, a more high frequent one for new,
unverified snapshots, and a low frequency to re-verify older snapshots,
e.g., monthly.

Fix this case again, rework the code to avoid this easy to oversee
invariant. Use a nested match to better express the implication of
each setting, and add some comments.

Stefan Reiter 91c9b42da3 fix #2934: list to-be-installed packages in updates
As always, libapt is mocking us with complexity, but we can get the
approximate result we want by retrieving dependencies of all
to-be-updated packages and then seeing if they are missing.

If they are, we assume they will be installed.

For this, query_detailed_info is extended to allow reading details for
non-installed packages, and this is also exposed in
list_installed_apt_packages via 'all_versions_for'. This is necessary so
we can retrieve changelogs for such packages.

Note that we cannot retrieve all that information all the time, as
querying details for packages that aren't installed takes a rather long
time.

Dylan Whyte afef7f3bba fix #3038: check user before renewing ticket
Fixes a bug in which the userid of the ticket cache is updated,
when a user connects, but the ticket itself is not.
This means a newly connected user has a previously connected
user's ticket and thus, cannot do anything, as the client will
attempt to use the invalid ticket.

e.g. if john@pbs connected to the server first, followed by
mike@pbs, the following would be stored in the ticket cache.

{
  "localhost": {
    "mike@pbs": {
      "ticket": "PBS:john@pbs:AAAA",
      "timestamp": 1601039326,

Thomas Lamprecht 9e870b5f39 log rotate: do NOT compress first rotation
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.

Thomas Lamprecht e6ca9c3235 log rotate: do NOT overwrite file with possible writers
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.

Thomas Lamprecht 8e7e2223d8 server/rest: implement request access log
reuse the FileLogger module in append mode.
As it implements write, which is not thread safe (mutable self) and
we use it in a async context we need to serialize access using a
mutex.

Try to use the same format we do in pveproxy, namely the one which is
also used in apache or nginx by default.

Use the response extensions to pass up the userid, if we extract it
from a ticket.

The privileged and unprivileged dameons log both to the same file, to
have a unified view, and avoiding the need to handle more log files.
We avoid extra intra-process locking by reusing the fact that a write
smaller than PIPE_BUF (4k on linux) is atomic for files opened with
the 'O_APPEND' flag. For now the logged request path is not yet
guaranteed to be smaller than that, this will be improved in a future
patch.

Thomas Lamprecht 4703ba81ce server: rest: implement max URI path and query length request limits
Add a generous limit now and return the correct error (414 URI Too
Long). Otherwise we could to pretty larger GET requests, 64 KiB and
possible bigger (at 64 KiB my simple curl test failed due to
shell/curl limitations).

For now allow a 3072 characters as combined length of URI path and
query.

This is conform with the HTTP/1.1 RFCs (e.g., RFC 7231, 6.5.12 and
RFC 2616, 3.2.1) which do not specify any limits, upper or lower, but
require that all server accessible resources mus be reachable without
getting 414, which is normally fulfilled as we have various length
limits for stuff which could be in an URI, in place, e.g.:
 * user id: max. 64 chars
 * datastore: max. 32 chars

The only known problematic API endpoint is the catalog one, used in
the GUI's pxar file browser:
GET /api2/json/admin/datastore/<id>/catalog?..&filepath=<path>

The <path> is the encoded archive path, and can be arbitrary long.

But, this is a flawed design, as even without this new limit one can
easily generate archives which cannot be browsed anymore, as hyper
only accepts requests with max. 64 KiB in the URI.
So rather, we should move that to a GET-as-POST call, which has no
such limitations (and would not need to base32 encode the path).

Note: This change was inspired by adding a request access log, which
profits from such limits as we can then rely on certain atomicity
guarantees when writing requests to the log.

Thomas Lamprecht fe0efb25e8 backup: index readers: drop useless shared lock
This is only acquired in those two methods, both as shared. So it has
no use.

It seems, that it was planned in the past that the index deletion
should take the exclusive, while read and write takes the shared
flock on the index, as one can guess from the lock comments in commit
0465218953

But then later, in commit c8ec450e37)
the documented semantics where changed to use a temp file and do an
atomic rename instead for atomicity.

The reader shared flock on the index file was done inbetween,
probably as preparatory step, but was not removed again when strategy
was changed to using the file rename instead.

Do so now, to avoid confusion of readers and a useless flock.

Fabian Grünbichler d479f0c810 reader: track index chunks and limit access
a reader connection should not be allowed to read arbitrary chunks in
the datastore, but only those that were previously registered by opening
the corresponding index files.

this mechanism is needed to allow unprivileged users (that don't have
full READ permissions on the whole datastore) access to their own
backups via a reader environment.

Thomas Lamprecht 41bfd24919 server: add Datastore.Allocate privilege
Previously only Datastore.Modify was required for creating a new
datastore.

But, that endpoint allows one to pass an arbitrary path, of which all
parent directories will be created, this can allow any user with the
"Datastore Admin" role on "/datastores" to do some damage to the
system. Further, it is effectively a side channel for revealing the
systems directory structure through educated guessing and error
handling.

Add a new privilege "Datastore.Allocate" which, for now, is used
specifically for the create datastore API endpoint.

Add it only to the "Admin" role.

Stefan Reiter 735ee5206a fuse_loop: handle unmap on crashed instance
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.

Stefan Reiter 2deee0e01f fuse_loop: add automatic cleanup of run files and dangling instances
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.

Stefan Reiter 2d7d6e61be mount/map: use names for map/unmap for easier use
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.

Stefan Reiter 45f9b32e0f client: implement map/unmap commands for .img backups
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.

while we probably do not add much more to them, it still looks ugly.

If this was made so that adding a World readable API call is "hard"
and not done by accident, it rather should be done as a test on build
time. But, IMO, the API permission schema definitions are easy to
review, and not often changed/added - so any wrong World readable API
call will normally still caught.

Thomas Lamprecht 79f6a79cfc assume correct backup, avoid verifying chunk existance
This can slow things down by a lot on setups with (relatively) high
seek time, in the order of doubling the backup times if cache isn't
populated with the last backups chunk inode info.

Effectively there's nothing known this protects us from in the
codebase. The only thing which was theorized about was the case
where a really long running backup job (over 24 hours) is still
running and writing new chunks, not indexed yet anywhere, then an
update (or manual action) triggers a reload of the proxy. There was
some theory that then a GC in the new daemon would not know about the
oldest writer in the old one, and thus use a less strict atime limit
for chunk sweeping - opening up a window for deleting chunks from the
long running backup.
But, this simply cannot happen as we have a per datastore process
wide flock, which is acquired shared by backup jobs and exclusive by
GC. In the same process GC and backup can both get it, as it has a
process locking granularity. If there's an old daemon with a writer,
that also has the lock open shared, and so no GC in the new process
can get exclusive access to it.

So, with that confirmed we have no need for a "half-assed"
verification in the backup finish step. Rather, we plan to add an
opt-in "full verify each backup on finish" option (see #2988)
