udf_rename(): only access the child content on cross-directory rename

[ Upstream commit 9d35cebb794bb7be93db76c3383979c7deacfef9 ]

We can't really afford locking the source on same-directory rename;
currently vfs_rename() tries to do that, but it will have to be
changed. The logics in udf_rename() is lazy and goes looking for
".." in source even in same-directory case. It's not hard to get
rid of that, leaving that behaviour only for cross-directory case;
that VFS can get locks safely (and will keep doing that after the
coming changes).

udf: Fix bogus checksum computation in udf_rename()

[ Upstream commit 27ab33854873e6fb958cb074681a0107cc2ecc4c ]

Syzbot reports uninitialized memory access in udf_rename() when updating
checksum of '..' directory entry of a moved directory. This is indeed
true as we pass on-stack diriter.fi to the udf_update_tag() and because
that has only struct fileIdentDesc included in it and not the impUse or
name fields, the checksumming function is going to checksum random stack
contents beyond the end of the structure. This is actually harmless
because the following udf_fiiter_write_fi() will recompute the checksum
from on-disk buffers where everything is properly included. So all that
is needed is just removing the bogus calculation.

Merge tag 'v6.6-vfs.ctime' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs timestamp updates from Christian Brauner:
"This adds VFS support for multi-grain timestamps and converts tmpfs,
xfs, ext4, and btrfs to use them. This carries acks from all relevant
filesystems.

The VFS always uses coarse-grained timestamps when updating the ctime
and mtime after a change. This has the benefit of allowing filesystems
to optimize away a lot of metadata updates, down to around 1 per
jiffy, even when a file is under heavy writes.

Unfortunately, this has always been an issue when we're exporting via
NFSv3, which relies on timestamps to validate caches. A lot of changes
can happen in a jiffy, so timestamps aren't sufficient to help the
client decide to invalidate the cache.

Even with NFSv4, a lot of exported filesystems don't properly support
a change attribute and are subject to the same problems with timestamp
granularity. Other applications have similar issues with timestamps
(e.g., backup applications).

If we were to always use fine-grained timestamps, that would improve
the situation, but that becomes rather expensive, as the underlying
filesystem would have to log a lot more metadata updates.

This introduces fine-grained timestamps that are used when they are
actively queried.

This uses the 31st bit of the ctime tv_nsec field to indicate that
something has queried the inode for the mtime or ctime. When this flag
is set, on the next mtime or ctime update, the kernel will fetch a
fine-grained timestamp instead of the usual coarse-grained one.

As POSIX generally mandates that when the mtime changes, the ctime
must also change the kernel always stores normalized ctime values, so
only the first 30 bits of the tv_nsec field are ever used.

Filesytems can opt into this behavior by setting the FS_MGTIME flag in
the fstype. Filesystems that don't set this flag will continue to use
coarse-grained timestamps.

Various preparatory changes, fixes and cleanups are included:

- Fixup all relevant places where POSIX requires updating ctime
together with mtime. This is a wide-range of places and all
maintainers provided necessary Acks.

- Add new accessors for inode->i_ctime directly and change all
callers to rely on them. Plain accesses to inode->i_ctime are now
gone and it is accordingly rename to inode->__i_ctime and commented
as requiring accessors.

- Extend generic_fillattr() to pass in a request mask mirroring in a
sense the statx() uapi. This allows callers to pass in a request
mask to only get a subset of attributes filled in.

- Rework timestamp updates so it's possible to drop the @now
parameter the update_time() inode operation and associated helpers.

- Add inode_update_timestamps() and convert all filesystems to it
removing a bunch of open-coding"

Merge tag 'v6.5/vfs.rename.locking' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs rename locking updates from Christian Brauner:
"This contains the work from Jan to fix problems with cross-directory
renames originally reported in [1].

To quickly sum it up some filesystems (so far we know at least about
ext4, udf, f2fs, ocfs2, likely also reiserfs, gfs2 and others) need to
lock the directory when it is being renamed into another directory.

This is because we need to update the parent pointer in the directory
in that case and if that races with other operations on the directory,
in particular a conversion from one directory format into another, bad
things can happen.

So far we've done the locking in the filesystem code but recently
Darrick pointed out in [2] that the RENAME_EXCHANGE case was missing.
That one is particularly nasty because RENAME_EXCHANGE can arbitrarily
mix regular files and directories and proper lock ordering is not
achievable in the filesystems alone.

This patch set adds locking into vfs_rename() so that not only parent
directories but also moved inodes, regardless of whether they are
directories or not, are locked when calling into the filesystem.

This means establishing a locking order for unrelated directories. New
helpers are added for this purpose and our documentation is updated to
cover this in detail.

The locking is now actually easier to follow as we now always lock
source and target. We've always locked the target independent of
whether it was a directory or file and we've always locked source if
it was a regular file. The exact details for why this came about can
be found in [3] and [4]"
