XFS_IFORK_Q is supposed to be a predicate, not a function returning a
value. Its usage is in xchk_bmap_check_rmaps is incorrect, but that
function only cares about whether or not the "size" of the data is zero
or not. Convert that logic to use a proper boolean, and teach the
caller to skip the call entirely if the end result would be that we'd do
nothing anyway. This avoids a crash later in this series.

Now that we fully verify the inode forks before they are added to the
inode cache, the crash reported in
https://bugzilla.kernel.org/show_bug.cgi?id=204031
can't happen anymore, as we'll never let an inode that has inconsistent
nextents counts vs the presence of an in-core attr fork leak into the
inactivate code path. So remove the work around to try to handle the
case, and just return an error and warn if the fork is not present.

Call the data/attr local fork verifiers as soon as we are ready for them.
This keeps them close to the code setting up the forks, and avoids a

The split between xfs_inode_verify_forks and the two helpers
implementing the actual functionality is a little strange. Reshuffle
it so that xfs_inode_verify_forks verifies if the data and attr forks
are actually in local format and only call the low-level helpers if
that is the case. Handle the actual error reporting in the low-level
handlers to streamline the caller.

xfs_ifork_ops add up to two indirect calls per inode read and flush,
despite just having a single instance in the kernel. In xfsprogs
phase6 in xfs_repair overrides the verify_dir method to deal with inodes
that do not have a valid parent, but that can be fixed pretty easily
by ensuring they always have a valid looking parent.

xfs_iformat_fork is a weird catchall. Split it into one helper for
the data fork and one for the attr fork, and then call both helper
as well as the COW fork initialization from xfs_inode_from_disk. Order
the COW fork initialization after the attr fork initialization given
that it can't fail to simplify the error handling.
Note that the newly split helpers are moved down the file in

While QAing the new xfs_repair quotacheck code, I uncovered a quota
corruption bug resulting from a bad interaction between dquot buffer
initialization and quotacheck. The bug can be reproduced with the
following sequence:
# mkfs.xfs -f /dev/sdf
# mount /dev/sdf /opt -o usrquota
# su nobody -s /bin/bash -c 'touch /opt/barf'
# sync
# xfs_quota -x -c 'report -ahi' /opt
User quota on /opt (/dev/sdf)
Inodes
User ID Used Soft Hard Warn/Grace
---------- ---------------------------------
root 3 0 0 00 [------]
nobody 1 0 0 00 [------]
# xfs_io -x -c 'shutdown' /opt
# umount /opt
# mount /dev/sdf /opt -o usrquota
# touch /opt/man2
# xfs_quota -x -c 'report -ahi' /opt
User quota on /opt (/dev/sdf)
Inodes
User ID Used Soft Hard Warn/Grace
---------- ---------------------------------
root 1 0 0 00 [------]
nobody 1 0 0 00 [------]
# umount /opt
Notice how the initial quotacheck set the root dquot icount to 3
(rootino, rbmino, rsumino), but after shutdown -> remount -> recovery,
xfs_quota reports that the root dquot has only 1 icount. We haven't
deleted anything from the filesystem, which means that quota is now
under-counting. This behavior is not limited to icount or the root
dquot, but this is the shortest reproducer.
I traced the cause of this discrepancy to the way that we handle ondisk
dquot updates during quotacheck vs. regular fs activity. Normally, when
we allocate a disk block for a dquot, we log the buffer as a regular
(dquot) buffer. Subsequent updates to the dquots backed by that block
are done via separate dquot log item updates, which means that they
depend on the logged buffer update being written to disk before the
dquot items. Because individual dquots have their own LSN fields, that
initial dquot buffer must always be recovered.
However, the story changes for quotacheck, which can cause dquot block
allocations but persists the final dquot counter values via a delwri
list. Because recovery doesn't gate dquot buffer replay on an LSN, this
means that the initial dquot buffer can be replayed over the (newer)
contents that were delwritten at the end of quotacheck. In effect, this
re-initializes the dquot counters after they've been updated. If the
log does not contain any other dquot items to recover, the obsolete
dquot contents will not be corrected by log recovery.
Because quotacheck uses a transaction to log the setting of the CHKD
flags in the superblock, we skip quotacheck during the second mount
call, which allows the incorrect icount to remain.
Fix this by changing the ondisk dquot initialization function to use
ordered buffers to write out fresh dquot blocks if it detects that we're
running quotacheck. If the system goes down before quotacheck can
complete, the CHKD flags will not be set in the superblock and the next
mount will run quotacheck again, which can fix uninitialized dquot
buffers. This requires amending the defer code to maintaine ordered
buffer state across defer rolls for the sake of the dquot allocation
code.
For regular operations we preserve the current behavior since the dquot
items require properly initialized ondisk dquot records.

The attr fork can transition from shortform to leaf format while
empty if the first xattr doesn't fit in shortform. While this empty
leaf block state is intended to be transient, it is technically not
due to the transactional implementation of the xattr set operation.
We historically have a couple of bandaids to work around this
problem. The first is to hold the buffer after the format conversion
to prevent premature writeback of the empty leaf buffer and the
second is to bypass the xattr count check in the verifier during
recovery. The latter assumes that the xattr set is also in the log
and will be recovered into the buffer soon after the empty leaf
buffer is reconstructed. This is not guaranteed, however.
If the filesystem crashes after the format conversion but before the
xattr set that induced it, only the format conversion may exist in
the log. When recovered, this creates a latent corrupted state on
the inode as any subsequent attempts to read the buffer fail due to
verifier failure. This includes further attempts to set xattrs on
the inode or attempts to destroy the attr fork, which prevents the
inode from ever being removed from the unlinked list.
To avoid this condition, accept that an empty attr leaf block is a
valid state and remove the count check from the verifier. This means
that on rare occasions an attr fork might exist in an unexpected
state, but is otherwise consistent and functional. Note that we
retain the logic to avoid racing with metadata writeback to reduce
the window where this can occur.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.
