Subject: [PATCH] xfsrestore: fix rootdir due to xfsdump bulkstat misuse
If rootino is wrong and misspecified to a subdir inode #,
the following assertion could be triggered:
assert(ino != persp->p_rootino || hardh == persp->p_rooth);
This patch adds a '-x' option (another awkward thing is that
the codebase doesn't support long options) to address
problamatic images by searching for the real dir, the reason
that I don't enable it by default is that I'm not very confident
with the xfsrestore codebase and xfsdump bulkstat issue will
also be fixed immediately as well, so this function might be
optional and only useful for pre-exist corrupted dumps.
In details, my understanding of the original logic is
1) xfsrestore will create a rootdir node_t (p_rooth);
2) it will build the tree hierarchy from inomap and adopt
the parent if needed (so inodes whose parent ino hasn't
detected will be in the orphan dir, p_orphh);
3) during this period, if ino == rootino and
hardh != persp->p_rooth (IOWs, another node_t with
the same ino # is created), that'd be definitely wrong.
So the proposal fix is that
- considering the xfsdump root ino # is a subdir inode, it'll
trigger ino == rootino && hardh != persp->p_rooth condition;
- so we log this node_t as persp->p_rooth rather than the
initial rootdir node_t created in 1);
- we also know that this node is actually a subdir, and after
the whole inomap is scanned (IOWs, the tree is built),
the real root dir will have the orphan dir parent p_orphh;
- therefore, we walk up by the parent until some node_t has
the p_orphh, so that's it.

Subject: [PATCH 1/4] xfsrestore: fix on-media inventory media unpacking
When xfsrestore reads the inventory from tape media it fails to convert
media file records from bigendian. If the xfsdump inventory is not
available xfsrestore will write this invalid record to the on-line
inventory.

The invalid start and end inode information cause xfsrestore to consider
that non-directory files do not reside in the current media and will
fail to restore them.
The behaviour of an initial restore may succeed if the position of the
tape is such that the data file is encountered before the inventory
file, or if there is only one dump session on tape, xfsrestore is
somewhat inconsistent in this regard. Subsequent restores will use the
invalid on-line inventory and fail to restore files.
Fix this by correctly unpacking the inventory data.

Subject: [PATCH] xfsrestore: suggest -x rather than assert for false roots
If we're going to have a fix for false root problems its a good idea to
let people know that there's a way to recover, error out with a useful
message that mentions the `-x` option rather than just assert.
Before
xfsrestore: searching media for directory dump
xfsrestore: reading directories
xfsrestore: tree.c:757: tree_begindir: Assertion `ino != persp->p_rootino || hardh == persp->p_rooth' failed.
Aborted
After
xfsrestore: ERROR: tree.c:791: tree_begindir: Assertion `ino != persp->p_rootino || hardh == persp->p_rooth` failed.
xfsrestore: ERROR: False root detected. Recovery may be possible using the `-x` option
Aborted
