Merge tag 'v6.4/vfs.acl' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull acl updates from Christian Brauner:
"After finishing the introduction of the new posix acl api last cycle
the generic POSIX ACL xattr handlers are still around in the
filesystems xattr handlers for two reasons:

(1) Because a few filesystems rely on the ->list() method of the
generic POSIX ACL xattr handlers in their ->listxattr() inode
operation.

(2) POSIX ACLs are only available if IOP_XATTR is raised. The
IOP_XATTR flag is raised in inode_init_always() based on whether
the sb->s_xattr pointer is non-NULL. IOW, the registered xattr
handlers of the filesystem are used to raise IOP_XATTR. Removing
the generic POSIX ACL xattr handlers from all filesystems would
risk regressing filesystems that only implement POSIX ACL support
and no other xattrs (nfs3 comes to mind).

This contains the work to decouple POSIX ACLs from the IOP_XATTR flag
as they don't depend on xattr handlers anymore. So it's now possible
to remove the generic POSIX ACL xattr handlers from the sb->s_xattr
list of all filesystems. This is a crucial step as the generic POSIX
ACL xattr handlers aren't used for POSIX ACLs anymore and POSIX ACLs
don't depend on the xattr infrastructure anymore.

Adressing problem (1) will require more long-term work. It would be
best to get rid of the ->list() method of xattr handlers completely at
some point.

For erofs, ext{2,4}, f2fs, jffs2, ocfs2, and reiserfs the nop POSIX
ACL xattr handler is kept around so they can continue to use
array-based xattr handler indexing.

This update does simplify the ->listxattr() implementation of all
these filesystems however"

Pull vfs idmapping updates from Christian Brauner:

Merge tag 'fs.idmapped.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull vfs idmapping updates from Christian Brauner:

- Last cycle we introduced the dedicated struct mnt_idmap type for
mount idmapping and the required infrastucture in 256c8aed2b42 ("fs:
introduce dedicated idmap type for mounts"). As promised in last
cycle's pull request message this converts everything to rely on
struct mnt_idmap.

Currently we still pass around the plain namespace that was attached
to a mount. This is in general pretty convenient but it makes it easy
to conflate namespaces that are relevant on the filesystem with
namespaces that are relevant on the mount level. Especially for
non-vfs developers without detailed knowledge in this area this was a
potential source for bugs.

This finishes the conversion. Instead of passing the plain namespace
around this updates all places that currently take a pointer to a
mnt_userns with a pointer to struct mnt_idmap.

Now that the conversion is done all helpers down to the really
low-level helpers only accept a struct mnt_idmap argument instead of
two namespace arguments.

Conflating mount and other idmappings will now cause the compiler to
complain loudly thus eliminating the possibility of any bugs. This
makes it impossible for filesystem developers to mix up mount and
filesystem idmappings as they are two distinct types and require
distinct helpers that cannot be used interchangeably.

Everything associated with struct mnt_idmap is moved into a single
separate file. With that change no code can poke around in struct
mnt_idmap. It can only be interacted with through dedicated helpers.
That means all filesystems are and all of the vfs is completely
oblivious to the actual implementation of idmappings.

We are now also able to extend struct mnt_idmap as we see fit. For
example, we can decouple it completely from namespaces for users that
don't require or don't want to use them at all. We can also extend
the concept of idmappings so we can cover filesystem specific
requirements.

In combination with the vfs{g,u}id_t work we finished in v6.2 this
makes this feature substantially more robust and thus difficult to
implement wrong by a given filesystem and also protects the vfs.

- Enable idmapped mounts for tmpfs and fulfill a longstanding request.

A long-standing request from users had been to make it possible to
create idmapped mounts for tmpfs. For example, to share the host's
tmpfs mount between multiple sandboxes. This is a prerequisite for
some advanced Kubernetes cases. Systemd also has a range of use-cases
to increase service isolation. And there are more users of this.

However, with all of the other work going on this was way down on the
priority list but luckily someone other than ourselves picked this
up.

As usual the patch is tiny as all the infrastructure work had been
done multiple kernel releases ago. In addition to all the tests that
we already have I requested that Rodrigo add a dedicated tmpfs
testsuite for idmapped mounts to xfstests. It is to be included into
xfstests during the v6.3 development cycle. This should add a slew of
additional tests.
