Normally the extended attributes in the inode body would have been
checked when the inode is first opened, but if someone is writing to
the block device while the file system is mounted, it's possible for
the inode table to get corrupted.  Add bounds checking to avoid
reading beyond the end of allocated memory if this happens.

In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock
by calling ext4_handle_dirty_dirblock() when it already has taken the
directory lock.  There is a similar self-deadlock in
ext4_incvert_inline_data_nolock() for data files which we'll fix at
the same time.

A simple reproducer demonstrating the problem:

    mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64
    mount -t ext4 -o dirsync /dev/vdc /vdc

If there are failures while changing the mount options in
__ext4_remount(), we need to restore the old mount options.

This commit fixes two problem.  The first is there is a chance that we
will free the old quota file names before a potential failure leading
to a use-after-free.  The second problem addressed in this commit is
if there is a failed read/write to read-only transition, if the quota
has already been suspended, we need to renable quota handling.

The ext4_dirhash() will *almost* never fail, especially when the hash
tree feature was first introduced.  However, with the addition of
support of encrypted, casefolded file names, that function can most
certainly fail today.

So make sure the callers of ext4_dirhash() properly check for
failures, and reflect the errors back up to their callers.

When ext4_iomap_overwrite_begin() calls ext4_iomap_begin() map blocks may
fail for some reason (e.g. memory allocation failure, bare disk write), and
later because "iomap->type ! = IOMAP_MAPPED" triggers WARN_ON(). When ext4
iomap_begin() returns an error, it is normal that the type of iomap->type
may not match the expectation. Therefore, we only determine if iomap->type
is as expected when ext4_iomap_begin() is executed successfully.

It reduces ext4's compiled text size, and makes the code more efficient
(we remove an extra indirect reference and a potential byte
swap on big endian systems), and there is no downside. It also avoids the
potential KASAN / syzkaller failure, as a bonus.

When using cached extent stored in extent status tree in tree->cache_es
another process holding ei->i_es_lock for reading can be racing with us
setting new value of tree->cache_es. If the compiler would decide to
refetch tree->cache_es at an unfortunate moment, it could result in a
bogus in_range() check. Fix the possible race by using READ_ONCE() when
using tree->cache_es only under ei->i_es_lock for reading.

Ext4 has a filesystem wide lock protecting ext4_writepages() calls to

                  ext4_writepages() tries to acquire sbi->s_writepages_rwsem
                    and blocks forever

In ext4_xattr_move_to_block(), the value of the extended attribute
which we need to move to an external block may be allocated by
kvmalloc() if the value is stored in an external inode.  So at the end
of the function the code tried to check if this was the case by
testing entry->e_value_inum.

However, at this point, the pointer to the xattr entry is no longer
valid, because it was removed from the original location where it had
been stored.  So we could end up calling kvfree() on a pointer which
was not allocated by kvmalloc(); or we could also potentially leak
memory by not freeing the buffer when it should be freed.  Fix this by
storing whether it should be freed in a separate variable.

If a malicious fuzzer overwrites the ext4 superblock while it is

Previously, ext4_get_group_info() would treat an invalid group number
as BUG(), since in theory it should never happen.  However, if a
malicious attaker (or fuzzer) modifies the superblock via the block
device while it is the file system is mounted, it is possible for
s_first_data_block to get set to a very large number.  In that case,
when calculating the block group of some block number (such as the
starting block of a preallocation region), could result in an
underflow and very large block group number.  Then the BUG_ON check in
ext4_get_group_info() would fire, resutling in a denial of service
attack that can be triggered by root or someone with write access to
the block device.

For a quality of implementation perspective, it's best that even if
the system administrator does something that they shouldn't, that it
will not trigger a BUG.  So instead of BUG'ing, ext4_get_group_info()
will call ext4_error and return NULL.  We also add fallback code in
all of the callers of ext4_get_group_info() that it might NULL.

Also, since ext4_get_group_info() was already borderline to be an
inline function, un-inline it.  The results in a next reduction of the
compiled text size of ext4 by roughly 2k.

 "Just a few minor fixes for drivers, and a deletion of a file that is
  woefully out-of-date these days"

* tag 'block-6.4-2023-05-13' of git://git.kernel.dk/linux:
  Documentation/block: drop the request.rst file
  ublk: fix command op code check
  block/rnbd: replace REQ_OP_FLUSH with REQ_OP_WRITE
  nbd: Fix debugfs_create_dir error checking

SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout
(leaving only the last 2 bytes of the address):

  3bff <zen_untrain_ret>:
  3bff:       f3 0f 1e fa             endbr64
  3c03:       f6                      test   $0xcc,%bl

  3c05:       cc                      int3
  3c06:       0f ae e8                lfence

However, "the RET at __x86_return_thunk must be on a 64 byte boundary,
for alignment within the BTB."

Use SYM_START instead.

Pull more btrfs fixes from David Sterba:

 - fix incorrect number of bitmap entries for space cache if loading is
   interrupted by some error

 - fix backref walking, this breaks a mode of LOGICAL_INO_V2 ioctl that
   is used in deduplication tools

 - zoned mode fixes:
      - properly finish zone reserved for relocation
      - correctly calculate super block zone end on ZNS
      - properly initialize new extent buffer for redirty

 - make mount option clear_cache work with block-group-tree, to rebuild
   free-space-tree instead of temporarily disabling it that would lead
   to a forced read-only mount

 - fix alignment check for offset when printing extent item

* tag 'for-6.4-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux:
  btrfs: make clear_cache mount option to rebuild FST without disabling it
  btrfs: zero the buffer before marking it dirty in btrfs_redirty_list_add

Pull cifs client fixes from Steve French:

 - fix for copy_file_range bug for very large files that are multiples
   of rsize

 - do not ignore "isolated transport" flag if set on share

 - set rasize default better

 - three fixes related to shutdown and freezing (fixes 4 xfstests, and
   closes deferred handles faster in some places that were missed)

  cifs: fix pcchunk length type in smb2_copychunk_range

Pull vfs fix from Christian Brauner:
 "During the pipe nonblock rework the check for both O_NONBLOCK and
  IOCB_NOWAIT was dropped. Both checks need to be performed to ensure
  that files without O_NONBLOCK but IOCB_NOWAIT don't block when writing
  to or reading from a pipe.

  This just contains the fix adding the check for IOCB_NOWAIT back in"

Pull RISC-V fix from Palmer Dabbelt:
 "Just a single fix this week for a build issue. That'd usually be a
  good sign, but we've started to get some reports of boot failures on
  some hardware/bootloader configurations. Nothing concrete yet, but
  I've got a funny feeling that's where much of the bug hunting is going
  right now.

  Nothing's reproducing on my end, though, and this fixes some pretty
  concrete issues so I figured there's no reason to delay it:

   - a fix to the linker script to avoid orpahaned sections in
     kernel/pi"

Pipe reads or writes need to enable nonblocking attempts, if either
O_NONBLOCK is set on the file, or IOCB_NOWAIT is set in the iocb being
passed in. The latter isn't currently true, ensure we check for both
before waiting on data or space.

In case of CONFIG_BLKDEV_UBLK_LEGACY_OPCODES, type of cmd opcode could
be 0 or 'u'; and type can only be 'u' if CONFIG_BLKDEV_UBLK_LEGACY_OPCODES
isn't set.

So fix the wrong check.

Since flush bios are implemented as writes with no data and
the preflush flag per Christoph's comment [1].

And we need to change it in rnbd accordingly. Otherwise, I
got splatting when create fs from rnbd client.

The debugfs_create_dir function returns ERR_PTR in case of error, and the
only correct way to check if an error occurred is 'IS_ERR' inline function.
This patch will replace the null-comparison with IS_ERR.
