Axel Burri 0e6c1f9025 btrbk: fix regression: call "sudo readlink" for backend=btrfs-progs-sudo 
It is possible that the subvolume path is not accessible by the user
calling btrbk. When resolving mount points, "readlink" is used on the
path, which also needs to be wrapped with "sudo".

The FORCE_PRESERVE information is set on the node, and was lost for
"latest common target" as get_receive_targets() returned vinfo without
node information.

Axel Burri 526e332b02 ssh_filter_btrbk.sh: bugfix: ignore --restrict-path for "btrfs subvolume list" 
btrbk now runs "btrfs subvolume list" from the mountpoint instead of
the volume path, which for some users is not below --restrict-path. As
the output of "btrfs subvolume list" is the same (complete btrfs tree
for the filesystem), it is ok to ignore the restrict-path here.

Axel Burri 069304f3bb btrbk: use system_list_mountinfo(), remove system_list_mounts(); rename fs_spec -> mount_source 
Reasons for changing to `cat /proc/self/mountinfo`:
 - `/proc/self/mounts` (or `/proc/mounts`) lacks extra info
   (namespaces) and is not documented in kernel (deprecated?).
 - findmnt(8) also uses /proc/self/mountinfo

Axel Burri 0d124a4373 btrbk: fix regression in get_related_subvolumes(): correctly match same btrbk file name scheme 
Since we consider all accessible subvolumes in get_related_subvolumes,
checking for equal BTRBK_BASENAME and empty SUBVOL_DIR does not work
when checking for same btrbk file name scheme.

fixes regression: b37ef84e36 (btrbk: always read mountpoints; include all snapshots from mountpoint as candidates for best common parent)

Axel Burri faec212324 btrbk: check if received subvolume is really garbled before deleting it 
Improve error handling in btrfs_send_receive: on error, always try to
read the target subvolume and only delete it automatically if it is
garbled (read/write, no received_uuid).

This is especially important if the target subvolume was already
present before send/receive.

Reverts: 4c4afe77 btrbk: skip target metadata test if send/receive has errors

Axel Burri de57efff82 btrbk: bugfix: print all errors if send/receive fails 
If stream_compress is enabled and compress command is not found, we
now print "command not found".

Axel Burri 9aeaf2b15c btrbk: fix regression introduced with btrfs_subvolume_list_complete 
If btrfs_subvolume_show($vol, rootid => 5) fails, there are no
"received_uuid" and no "gen" keys in the root node.

Fixes: 0acbf74c57 (btrbk: add btrfs_subvolume_list_complete: fetch all subvolumes with all flags)

Axel Burri 669a34357a btrbk: bugfix: handle corner case: url="ssh://my.host" (without trailing slash) 
As we allow <url> to be specified as "<hostname>:<directory>", an URL
"ssh://my.host" (without trailing slash) was parsed as hostname="ssh",
directory="/my.host".

Axel Burri 0acbf74c57 btrbk: add btrfs_subvolume_list_complete: fetch all subvolumes with all flags 
Wrapper, returns complete list of all subvolumes (including btrfs
root, id=5) with all flags. Requires three calls to btrfs-progs.

Adaptions and cleanup in btr_tree().

Axel Burri de5004c744 btrbk: abort subvolume if it is btrfs root (id=5) 
Btrfs root subvolume (id=5) have no UUID and cannot be backed
up. Abort if "subvolume ." is configured on btrfs root, e.g.:

  volume /path/to/btrfs_root
    subvolume .

Axel Burri b0d58fd0f1 btrbk: btr_tree: always read btrfs root node (id=5), hoping to get its uuid 
Note that the UUID for btrfs root (id=5) is not always present:

 - btrfs-progs < 4.12 does not support rootid lookup
 - UUID can be missing if filesystem was created with btrfs-progs < 4.16

Still we need to always read it, as the whole tree is cached and we
don't know if it will be used.

Axel Burri 1aa0fe1aad btrbk: remove obsolete realpath_cache update in btrfs_subvolume_show() 
Recent btrfs-progs do not print the real path any more, this is now
handled by btrfs_mountpoint() -> system_realpath().
