70b60c8d9b btrfs: wait for fixup workers before stopping cleaner kthread during umount 
commit 41fd1e94066a815a7ab0a7025359e9b40e4b3576 upstream.

During unmount, at close_ctree(), we have the following steps in this order:

1) Park the cleaner kthread - this doesn't destroy the kthread, it basically
   halts its execution (wake ups against it work but do nothing);

2) We stop the cleaner kthread - this results in freeing the respective
   struct task_struct;

3) We call btrfs_stop_all_workers() which waits for any jobs running in all
   the work queues and then free the work queues.

Syzbot reported a case where a fixup worker resulted in a crash when doing
a delayed iput on its inode while attempting to wake up the cleaner at
btrfs_add_delayed_iput(), because the task_struct of the cleaner kthread
was already freed. This can happen during unmount because we don't wait
for any fixup workers still running before we call kthread_stop() against
the cleaner kthread, which stops and free all its resources.

Fix this by waiting for any fixup workers at close_ctree() before we call
kthread_stop() against the cleaner and run pending delayed iputs.

The stack traces reported by syzbot were the following:

commit c3b47f49e83197e8dffd023ec568403bcdbb774b upstream.

[BUG]

   entry_SYSCALL_64_after_hwframe+0x77/0x7f

[CAUSE]
The allocation failure happens at the start_transaction() inside
prepare_to_relocate(), and during the error handling we call
unset_reloc_control(), which makes fs_info->balance_ctl to be NULL.

Then we continue the error path cleanup in btrfs_balance() by calling
reset_balance_state() which will call del_balance_item() to fully delete
the balance item in the root tree.

However during the small window between set_reloc_contrl() and
unset_reloc_control(), we can have a subvolume tree update and created a
reloc_root for that subvolume.

Then we go into the final btrfs_commit_transaction() of
del_balance_item(), and into btrfs_update_reloc_root() inside
commit_fs_roots().

That function checks if fs_info->reloc_ctl is in the merge_reloc_tree
stage, but since fs_info->reloc_ctl is NULL, it results a NULL pointer
dereference.

[FIX]
Just add extra check on fs_info->reloc_ctl inside
btrfs_update_reloc_root(), before checking
fs_info->reloc_ctl->merge_reloc_tree.

That DEAD_RELOC_TREE handling is to prevent further modification to the
reloc tree during merge stage, but since there is no reloc_ctl at all,
we do not need to bother that.

f08589057f btrfs: update target inode's ctime on unlink 
[ Upstream commit 3bc2ac2f8f0b78a13140fc72022771efe0c9b778 ]

Unlink changes the link count on the target inode. POSIX mandates that
the ctime must also change when this occurs.

According to https://pubs.opengroup.org/onlinepubs/9699919799/functions/unlink.html:

"Upon successful completion, unlink() shall mark for update the last data
 modification and last file status change timestamps of the parent
 directory. Also, if the file's link count is not 0, the last file status
 change timestamp of the file shall be marked for update."

912bcdc51b btrfs: initialize location to fix -Wmaybe-uninitialized in btrfs_lookup_dentry() 
[ Upstream commit b8e947e9f64cac9df85a07672b658df5b2bcff07 ]

Some arch + compiler combinations report a potentially unused variable
location in btrfs_lookup_dentry(). This is a false alert as the variable
is passed by value and always valid or there's an error. The compilers
cannot probably reason about that although btrfs_inode_by_name() is in
the same file.

   >  + /kisskb/src/fs/btrfs/inode.c: error: 'location.objectid' may be used
   +uninitialized in this function [-Werror=maybe-uninitialized]:  => 5603:9
   >  + /kisskb/src/fs/btrfs/inode.c: error: 'location.type' may be used
   +uninitialized in this function [-Werror=maybe-uninitialized]:  => 5674:5

   m68k-gcc8/m68k-allmodconfig
   mips-gcc8/mips-allmodconfig
   powerpc-gcc5/powerpc-all{mod,yes}config
   powerpc-gcc5/ppc64_defconfig

Initialize it to zero, this should fix the warnings and won't change the
behaviour as btrfs_inode_by_name() accepts only a root or inode item
types, otherwise returns an error.

c60676b81f btrfs: clean up our handling of refs == 0 in snapshot delete 
[ Upstream commit b8ccef048354074a548f108e51d0557d6adfd3a3 ]

In reada we BUG_ON(refs == 0), which could be unkind since we aren't
holding a lock on the extent leaf and thus could get a transient
incorrect answer.  In walk_down_proc we also BUG_ON(refs == 0), which
could happen if we have extent tree corruption.  Change that to return
-EUCLEAN.  In do_walk_down() we catch this case and handle it correctly,
however we return -EIO, which -EUCLEAN is a more appropriate error code.
Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert
that to proper error handling.  Also adjust the error message so we can
actually do something with the information.

ed1b61398c btrfs: replace BUG_ON with ASSERT in walk_down_proc() 
[ Upstream commit 1f9d44c0a12730a24f8bb75c5e1102207413cc9b ]

We have a couple of areas where we check to make sure the tree block is
locked before looking up or messing with references.  This is old code
so it has this as BUG_ON().  Convert this to ASSERT() for developers.

7e4c72dbaf btrfs: fix use-after-free after failure to create a snapshot 
commit 28b21c558a3753171097193b6f6602a94169093a upstream.

At ioctl.c:create_snapshot(), we allocate a pending snapshot structure and
then attach it to the transaction's list of pending snapshots. After that
we call btrfs_commit_transaction(), and if that returns an error we jump
to 'fail' label, where we kfree() the pending snapshot structure. This can
result in a later use-after-free of the pending snapshot:

1) We allocated the pending snapshot and added it to the transaction's
   list of pending snapshots;

2) We call btrfs_commit_transaction(), and it fails either at the first
   call to btrfs_run_delayed_refs() or btrfs_start_dirty_block_groups().
   In both cases, we don't abort the transaction and we release our
   transaction handle. We jump to the 'fail' label and free the pending
   snapshot structure. We return with the pending snapshot still in the
   transaction's list;

3) Another task commits the transaction. This time there's no error at
   all, and then during the transaction commit it accesses a pointer
   to the pending snapshot structure that the snapshot creation task
   has already freed, resulting in a user-after-free.

This issue could actually be detected by smatch, which produced the
following warning:

  fs/btrfs/ioctl.c:843 create_snapshot() warn: '&pending_snapshot->list' not removed from list

So fix this by not having the snapshot creation ioctl directly add the
pending snapshot to the transaction's list. Instead add the pending
snapshot to the transaction handle, and then at btrfs_commit_transaction()
we add the snapshot to the list only when we can guarantee that any error
returned after that point will result in a transaction abort, in which
case the ioctl code can safely free the pending snapshot and no one can
access it anymore.

8ec052c544 btrfs: delete pointless BUG_ON check on quota root in btrfs_qgroup_account_extent() 
[ Upstream commit f40a3ea94881f668084f68f6b9931486b1606db0 ]

The BUG_ON is deep in the qgroup code where we can expect that it
exists. A NULL pointer would cause a crash.

It was added long ago in 550d7a2ed5 ("btrfs: qgroup: Add new qgroup
calculation function btrfs_qgroup_account_extents()."). It maybe made
sense back then as the quota enable/disable state machine was not that
robust as it is nowadays, so we can just delete it.

[ Upstream commit e80e3f732cf53c64b0d811e1581470d67f6c3228 ]

Change BUG_ON to a proper error handling in the unlikely case of seeing
data when the command is started. This is supposed to be reset when the
command is finished (send_cmd, send_encoded_extent).

[ Upstream commit 6fbc6f4ac1f4907da4fc674251527e7dc79ffbf6 ]

The may_destroy_subvol() looks up a root by a key, allowing to do an
inexact search when key->offset is -1.  It's never expected to find such
item, as it would break the allowed range of a root id.

[ Upstream commit be73f4448b607e6b7ce41cd8ef2214fdf6e7986f ]

The pointer to root is initialized in btrfs_init_delayed_node(), no need
to check for it again. Change the BUG_ON to assertion.

6bcd0f95b8 btrfs: rename bitmap_set_bits() -> btrfs_bitmap_set_bits() 
commit 4ca532d64648d4776d15512caed3efea05ca7195 upstream.

bitmap_set_bits() does not start with the FS' prefix and may collide
with a new generic helper one day. It operates with the FS-specific
types, so there's no change those two could do the same thing.
Just add the prefix to exclude such possible conflict.

d88083916f btrfs: tree-checker: add dev extent item checks 
commit 008e2512dc5696ab2dc5bf264e98a9fe9ceb830e upstream.

[REPORT]
There is a corruption report that btrfs refused to mount a fs that has
overlapping dev extents:

  BTRFS error (device sdc): dev extent devid 4 physical offset 14263979671552 overlap with previous dev extent end 14263980982272
  BTRFS error (device sdc): failed to verify dev extents against chunks: -117
  BTRFS error (device sdc): open_ctree failed

[CAUSE]
The direct cause is very obvious, there is a bad dev extent item with
incorrect length.

With btrfs check reporting two overlapping extents, the second one shows
some clue on the cause:

  ERROR: dev extent devid 4 offset 14263979671552 len 6488064 overlap with previous dev extent end 14263980982272
  ERROR: dev extent devid 13 offset 2257707008000 len 6488064 overlap with previous dev extent end 2257707270144
  ERROR: errors found in extent allocation tree or chunk allocation

The second one looks like a bitflip happened during new chunk
allocation:
hex(2257707008000) = 0x20da9d30000
hex(2257707270144) = 0x20da9d70000
diff               = 0x00000040000

So it looks like a bitflip happened during new dev extent allocation,
resulting the second overlap.

Currently we only do the dev-extent verification at mount time, but if the
corruption is caused by memory bitflip, we really want to catch it before
writing the corruption to the storage.

Furthermore the dev extent items has the following key definition:

	(<device id> DEV_EXTENT <physical offset>)

Thus we can not just rely on the generic key order check to make sure
there is no overlapping.

[ENHANCEMENT]
Introduce dedicated dev extent checks, including:

- Fixed member checks
  * chunk_tree should always be BTRFS_CHUNK_TREE_OBJECTID (3)
  * chunk_objectid should always be
    BTRFS_FIRST_CHUNK_CHUNK_TREE_OBJECTID (256)

- Alignment checks
  * chunk_offset should be aligned to sectorsize
  * length should be aligned to sectorsize
  * key.offset should be aligned to sectorsize

- Overlap checks
  If the previous key is also a dev-extent item, with the same
  device id, make sure we do not overlap with the previous dev extent.

1d4e65fa62 btrfs: fix bitmap leak when loading free space cache on duplicate entry 
[ Upstream commit 320d8dc612660da84c3b70a28658bb38069e5a9a ]

If we failed to link a free space entry because there's already a
conflicting entry for the same offset, we free the free space entry but
we don't free the associated bitmap that we had just allocated before.
Fix that by freeing the bitmap before freeing the entry.

94818bdb00 btrfs: qgroup: fix quota root leak after quota disable failure 
[ Upstream commit a7e4c6a3031c74078dba7fa36239d0f4fe476c53 ]

If during the quota disable we fail when cleaning the quota tree or when
deleting the root from the root tree, we jump to the 'out' label without
ever dropping the reference on the quota root, resulting in a leak of the
root since fs_info->quota_root is no longer pointing to the root (we have
set it to NULL just before those steps).

Fix this by always doing a btrfs_put_root() call under the 'out' label.
This is a problem that exists since qgroups were first added in 2012 by
commit bed92eae26 ("Btrfs: qgroup implementation and prototypes"), but
back then we missed a kfree on the quota root and free_extent_buffer()
calls on its root and commit root nodes, since back then roots were not
yet reference counted.

05544fd3f1 btrfs: fix leak of qgroup extent records after transaction abort 
[ Upstream commit fb33eb2ef0d88e75564983ef057b44c5b7e4fded ]

Qgroup extent records are created when delayed ref heads are created and
then released after accounting extents at btrfs_qgroup_account_extents(),
called during the transaction commit path.

If a transaction is aborted we free the qgroup records by calling
btrfs_qgroup_destroy_extent_records() at btrfs_destroy_delayed_refs(),
unless we don't have delayed references. We are incorrectly assuming
that no delayed references means we don't have qgroup extents records.

We can currently have no delayed references because we ran them all
during a transaction commit and the transaction was aborted after that
due to some error in the commit path.

So fix this by ensuring we btrfs_qgroup_destroy_extent_records() at
btrfs_destroy_delayed_refs() even if we don't have any delayed references.

c48ab6a4cd btrfs: add missing mutex_unlock in btrfs_relocate_sys_chunks() 
commit 9af503d91298c3f2945e73703f0e00995be08c30 upstream.

The previous patch that replaced BUG_ON by error handling forgot to
unlock the mutex in the error path.

a2fb0eefa4 btrfs: fix kvcalloc() arguments order in btrfs_ioctl_send() 
commit 6ff09b6b8c2fb6b3edda4ffaa173153a40653067 upstream.

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:

fs/btrfs/send.c: In function 'btrfs_ioctl_send':
fs/btrfs/send.c:8208:44: warning: 'kvcalloc' sizes specified with 'sizeof'
in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
 8208 |         sctx->clone_roots = kvcalloc(sizeof(*sctx->clone_roots),
      |                                            ^

Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the result
and so this is not a bug. But it's still worth to fix it.

b34fdb24ab btrfs: always clear PERTRANS metadata during commit 
[ Upstream commit 6e68de0bb0ed59e0554a0c15ede7308c47351e2d ]

It is possible to clear a root's IN_TRANS tag from the radix tree, but
not clear its PERTRANS, if there is some error in between. Eliminate
that possibility by moving the free up to where we clear the tag.

e2a3a1df2f btrfs: make btrfs_clear_delalloc_extent() free delalloc reserve 
[ Upstream commit 3c6f0c5ecc8910d4ffb0dfe85609ebc0c91c8f34 ]

Currently, this call site in btrfs_clear_delalloc_extent() only converts
the reservation. We are marking it not delalloc, so I don't think it
makes sense to keep the rsv around.  This is a path where we are not
sure to join a transaction, so it leads to incorrect free-ing during
umount.

Helps with the pass rate of generic/269 and generic/475.

e2f5d61b5a btrfs: return accurate error code on open failure in open_fs_devices() 
[ Upstream commit 2f1aeab9fca1a5f583be1add175d1ee95c213cfa ]

When attempting to exclusive open a device which has no exclusive open
permission, such as a physical device associated with the flakey dm
device, the open operation will fail, resulting in a mount failure.

In this particular scenario, we erroneously return -EINVAL instead of the
correct error code provided by the bdev_open_by_path() function, which is
-EBUSY.

Fix this, by returning error code from the bdev_open_by_path() function.
With this correction, the mount error message will align with that of
ext4 and xfs.

This happens, because we're copying a 'struct btrfs_data_container' back
to user-space. This btrfs_data_container is allocated in
'init_data_container()' via kvmalloc(), which does not zero-fill the
memory.

Fix this by using kvzalloc() which zeroes out the memory on allocation.

[ Upstream commit 71537e35c324ea6fbd68377a4f26bb93a831ae35 ]

When running delayed inode updates, we do not record the inode's root in
the transaction, but we do allocate PREALLOC and thus converted PERTRANS
space for it. To be sure we free that PERTRANS meta rsv, we must ensure
that we record the root in the transaction.

commit 141fb8cd206ace23c02cd2791c6da52c1d77d42a upstream.

We use add_root_meta_rsv and sub_root_meta_rsv to track prealloc and
pertrans reservations for subvolumes when quotas are enabled. The
convert function does not properly increment pertrans after decrementing
prealloc, so the count is not accurate.

Note: we check that the fs is not read-only to mirror the logic in
qgroup_convert_meta, which checks that before adding to the pertrans rsv.

[ Upstream commit 26b66d1d366a375745755ca7365f67110bbf6bd5 ]

The get_parent handler looks up a parent of a given dentry, this can be
either a subvolume or a directory. The search is set up with offset -1
but it's never expected to find such item, as it would break allowed
range of inode number or a root id. This means it's a corruption (ext4
also returns this error code).

[ Upstream commit 7411055db5ce64f836aaffd422396af0075fdc99 ]

The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption,
as it could be caused only by two impossible conditions:

- at first the search key is set up to look for a chunk tree item, with
  offset -1, this is an inexact search and the key->offset will contain
  the correct offset upon a successful search, a valid chunk tree item
  cannot have an offset -1

- after first successful search, the found_key corresponds to a chunk
  item, the offset is decremented by 1 before the next loop, it's
  impossible to find a chunk item there due to alignment and size
  constraints

introduced when commit 173431b274a9 ("btrfs: defrag: reject unknown
flags of btrfs_ioctl_defrag_range_args") was backported to kernels
lacking this patch. Now with these two patches applied in reverse order,
range->flags needed to change back to range.flags.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.]

d2a9709728 btrfs: fix off-by-one chunk length calculation at contains_pending_extent() 
[ Upstream commit ae6bd7f9b46a29af52ebfac25d395757e2031d0d ]

At contains_pending_extent() the value of the end offset of a chunk we
found in the device's allocation state io tree is inclusive, so when
we calculate the length we pass to the in_range() macro, we must sum
1 to the expression "physical_end - physical_offset".

In practice the wrong calculation should be harmless as chunks sizes
are never 1 byte and we should never have 1 byte ranges of unallocated
space. Nevertheless fix the wrong calculation.

2886fe308a btrfs: dev-replace: properly validate device names 
commit 9845664b9ee47ce7ee7ea93caf47d39a9d4552c4 upstream.

There's a syzbot report that device name buffers passed to device
replace are not properly checked for string termination which could lead
to a read out of bounds in getname_kernel().

Add a helper that validates both source and target device name buffers.
For devid as the source initialize the buffer to empty string in case
something tries to read it later.

This was originally analyzed and fixed in a different way by Edward Adam
Davis (see links).

a1ccc4f441 btrfs: do not pin logs too early during renames 
[ Upstream commit bd54f381a12ac695593271a663d36d14220215b2 ]

During renames we pin the logs of the roots a bit too early, before the
calls to btrfs_insert_inode_ref(). We can pin the logs after those calls,
since those will not change anything in a log tree.

In a scenario where we have multiple and diverse filesystem operations
running in parallel, those calls can take a significant amount of time,
due to lock contention on extent buffers, and delay log commits from other
tasks for longer than necessary.

So just pin logs after calls to btrfs_insert_inode_ref() and right before
the first operation that can update a log tree.

The following script that uses dbench was used for testing:

  $ cat dbench-test.sh
  #!/bin/bash

  DEV=/dev/nvme0n1
  MNT=/mnt/nvme0n1
  MOUNT_OPTIONS="-o ssd"
  MKFS_OPTIONS="-m single -d single"

  echo "performance" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

  umount $DEV &> /dev/null
  mkfs.btrfs -f $MKFS_OPTIONS $DEV
  mount $MOUNT_OPTIONS $DEV $MNT

  dbench -D $MNT -t 120 16

  umount $MNT

The tests were run on a machine with 12 cores, 64G of RAN, a NVMe device
and using a non-debug kernel config (Debian's default config).

The results compare a branch without this patch and without the previous
patch in the series, that has the subject:

 "btrfs: eliminate some false positives when checking if inode was logged"

Versus the same branch with these two patches applied.

16b70511bd btrfs: unify lookup return value when dir entry is missing 
[ Upstream commit 8dcbc26194eb872cc3430550fb70bb461424d267 ]

btrfs_lookup_dir_index_item() and btrfs_lookup_dir_item() lookup for dir
entries and both are used during log replay or when updating a log tree
during an unlink.

However when the dir item does not exists, btrfs_lookup_dir_item() returns
NULL while btrfs_lookup_dir_index_item() returns PTR_ERR(-ENOENT), and if
the dir item exists but there is no matching entry for a given name or
index, both return NULL. This makes the call sites during log replay to
be more verbose than necessary and it makes it easy to miss this slight
difference. Since we don't need to distinguish between those two cases,
make btrfs_lookup_dir_index_item() always return NULL when there is no
matching directory entry - either because there isn't any dir entry or
because there is one but it does not match the given name and index.

Also rename the argument 'objectid' of btrfs_lookup_dir_index_item() to
'index' since it is supposed to match an index number, and the name
'objectid' is not very good because it can easily be confused with an
inode number (like the inode number a dir entry points to).

fccb8a6109 btrfs: introduce btrfs_lookup_match_dir 
[ Upstream commit a7d1c5dc8632e9b370ad26478c468d4e4e29f263 ]

btrfs_search_slot is called in multiple places in dir-item.c to search
for a dir entry, and then calling btrfs_match_dir_name to return a
btrfs_dir_item.

In order to reduce the number of callers of btrfs_search_slot, create a
common function that looks for the dir key, and if found call
btrfs_match_dir_item_name.

aaf2d6b7ec btrfs: tree-checker: check for overlapping extent items 
[ Upstream commit 899b7f69f244e539ea5df1b4d756046337de44a5 ]

We're seeing a weird problem in production where we have overlapping
extent items in the extent tree.  It's unclear where these are coming
from, and in debugging we realized there's no check in the tree checker
for this sort of problem.  Add a check to the tree-checker to make sure
that the extents do not overlap each other.
