xfs: Check for delayed allocations before setting extsize

commit 2a492ff66673c38a77d0815d67b9a8cce2ef57f8 upstream.

Extsize should only be allowed to be set on files with no data in it.
For this, we check if the files have extents but miss to check if
delayed extents are present. This patch adds that check.

While we are at it, also refactor this check into a helper since
it's used in some other places as well like xfs_inactive() or
xfs_ioctl_setattr_xflags()

**Without the patch (SUCCEEDS)**

$ xfs_io -c 'open -f testfile' -c 'pwrite 0 1024' -c 'extsize 65536'

wrote 1024/1024 bytes at offset 0
1 KiB, 1 ops; 0.0002 sec (4.628 MiB/sec and 4739.3365 ops/sec)

**With the patch (FAILS as expected)**

xfs: allow read IO and FICLONE to run concurrently

commit 14a537983b228cb050ceca3a5b743d01315dc4aa upstream.

One of our VM cluster management products needs to snapshot KVM image
files so that they can be restored in case of failure. Snapshotting is
done by redirecting VM disk writes to a sidecar file and using reflink
on the disk image, specifically the FICLONE ioctl as used by
"cp --reflink". Reflink locks the source and destination files while it
operates, which means that reads from the main vm disk image are blocked,
causing the vm to stall. When an image file is heavily fragmented, the
copy process could take several minutes. Some of the vm image files have
50-100 million extent records, and duplicating that much metadata locks
the file for 30 minutes or more. Having activities suspended for such
a long time in a cluster node could result in node eviction.

Clone operations and read IO do not change any data in the source file,
so they should be able to run concurrently. Demote the exclusive locks
taken by FICLONE to shared locks to allow reads while cloning. While a
clone is in progress, writes will take the IOLOCK_EXCL, so they block
until the clone completes.

Merge tag 'xfs-6.6-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Chandan Babu:

- Fix an integer overflow bug when processing an fsmap call

- Fix crash due to CPU hot remove event racing with filesystem mount
operation

- During read-only mount, XFS does not allow the contents of the log to
be recovered when there are one or more unrecognized rcompat features
in the primary superblock, since the log might have intent items
which the kernel does not know how to process

- During recovery of log intent items, XFS now reserves log space
sufficient for one cycle of a permanent transaction to execute.
Otherwise, this could lead to livelocks due to non-availability of
log space

- On an fs which has an ondisk unlinked inode list, trying to delete a
file or allocating an O_TMPFILE file can cause the fs to the shutdown
if the first inode in the ondisk inode list is not present in the
inode cache. The bug is solved by explicitly loading the first inode
in the ondisk unlinked inode list into the inode cache if it is not
already cached

A similar problem arises when the uncached inode is present in the
middle of the ondisk unlinked inode list. This second bug is
triggered when executing operations like quotacheck and bulkstat. In
this case, XFS now reads in the entire ondisk unlinked inode list

xfs: reload entire iunlink lists

This is the second part of correcting XFS to reload the incore unlinked
inode list from the ondisk contents. Whereas part one tackled failures
from regular filesystem calls, this part takes on the problem of needing
to reload the entire incore unlinked inode list on account of somebody
loading an inode that's in the /middle/ of an unlinked list. This
happens during quotacheck, bulkstat, or even opening a file by handle.

In this case we don't know the length of the list that we're reloading,
so we don't want to create a new unbounded memory load while holding
resources locked. Instead, we'll target UNTRUSTED iget calls to reload
the entire bucket.

Note that this changes the definition of the incore unlinked inode list
slightly -- i_prev_unlinked == 0 now means "not on the incore list".

Teach quotacheck to reload the unlinked inode lists when walking the

that a reloaded inode will get inactivated before quotacheck tries to

xfs: reload entire unlinked bucket lists

The previous patch to reload unrecovered unlinked inodes when adding a
newly created inode to the unlinked list is missing a key piece of
functionality. It doesn't handle the case that someone calls xfs_iget
on an inode that is not the last item in the incore list. For example,
if at mount time the ondisk iunlink bucket looks like this:

AGI -> 7 -> 22 -> 3 -> NULL

None of these three inodes are cached in memory. Now let's say that
someone tries to open inode 3 by handle. We need to walk the list to
make sure that inodes 7 and 22 get loaded cold, and that the
i_prev_unlinked of inode 3 gets set to 22.

xfs: use i_prev_unlinked to distinguish inodes that are not on the unlinked list

Alter the definition of i_prev_unlinked slightly to make it more obvious
when an inode with 0 link count is not part of the iunlink bucket lists
rooted in the AGI. This distinction is necessary because it is not
sufficient to check inode.i_nlink to decide if an inode is on the
unlinked list. Updates to i_nlink can happen while holding only
ILOCK_EXCL, but updates to an inode's position in the AGI unlinked list
(which happen after the nlink update) requires both ILOCK_EXCL and the
AGI buffer lock.

The next few patches will make it possible to reload an entire unlinked
bucket list when we're walking the inode table or performing handle
operations and need more than the ability to iget the last inode in the
chain.

The upcoming directory repair code also needs to be able to make this
distinction to decide if a zero link count directory should be moved to
the orphanage or allowed to inactivate. An upcoming enhancement to the
online AGI fsck code will need this distinction to check and rebuild the
AGI unlinked buckets.
