Merge tag 'lsm-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm updates from Paul Moore:

- Move the LSM hook comment blocks into security/security.c

For many years the LSM hook comment blocks were located in a very odd
place, include/linux/lsm_hooks.h, where they lived on their own,
disconnected from both the function prototypes and definitions.

In keeping with current kernel conventions, this moves all of these
comment blocks to the top of the function definitions, transforming
them into the kdoc format in the process. This should make it much
easier to maintain these comments, which are the main source of LSM
hook documentation.

For the most part the comment contents were left as-is, although some
glaring errors were corrected. Expect additional edits in the future
as we slowly update and correct the comment blocks.

This is the bulk of the diffstat.

- Introduce LSM_ORDER_LAST

Similar to how LSM_ORDER_FIRST is used to specify LSMs which should
be ordered before "normal" LSMs, the LSM_ORDER_LAST is used to
specify LSMs which should be ordered after "normal" LSMs.

This is one of the prerequisites for transitioning IMA/EVM to a
proper LSM.

- Remove the security_old_inode_init_security() hook

The security_old_inode_init_security() LSM hook only allows for a
single xattr which is problematic both for LSM stacking and the
IMA/EVM-as-a-LSM effort. This finishes the conversion over to the
security_inode_init_security() hook and removes the single-xattr LSM
hook.

- Fix a reiserfs problem with security xattrs

During the security_old_inode_init_security() removal work it became
clear that reiserfs wasn't handling security xattrs properly so we
fixed it.

ocfs2: Switch to security_inode_init_security()

In preparation for removing security_old_inode_init_security(), switch to
security_inode_init_security().

Extend the existing ocfs2_initxattrs() to take the
ocfs2_security_xattr_info structure from fs_info, and populate the
name/value/len triple with the first xattr provided by LSMs.

As fs_info was not used before, ocfs2_initxattrs() can now handle the case
of replicating the behavior of security_old_inode_init_security(), i.e.
just obtaining the xattr, in addition to setting all xattrs provided by
LSMs.

Supporting multiple xattrs is not currently supported where
security_old_inode_init_security() was called (mknod, symlink), as it
requires non-trivial changes that can be done at a later time. Like for
reiserfs, even if EVM is invoked, it will not provide an xattr (if it is
not the first to set it, its xattr will be discarded; if it is the first,
it does not have xattrs to calculate the HMAC on).

Finally, since security_inode_init_security(), unlike
security_old_inode_init_security(), returns zero instead of -EOPNOTSUPP if
no xattrs were provided by LSMs or if inodes are private, additionally
check in ocfs2_init_security_get() if the xattr name is set.

If not, act as if security_old_inode_init_security() returned -EOPNOTSUPP,
and set si->enable to zero to notify to the functions following
ocfs2_init_security_get() that no xattrs are available.

- After much discussion, David Laight's 'minmax: Relax type checks in

It does not contain the switch of the time fields to discrete 64 bit
