Merge tag 'lsm-pr-20230829' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:

 - Add proper multi-LSM support for xattrs in the
   security_inode_init_security() hook

   Historically the LSM layer has only allowed a single LSM to add an
   xattr to an inode, with IMA/EVM measuring that and adding its own as
   well. As we work towards promoting IMA/EVM to a "proper LSM" instead
   of the special case that it is now, we need to better support the
   case of multiple LSMs each adding xattrs to an inode and after
   several attempts we now appear to have something that is working
   well. It is worth noting that in the process of making this change we
   uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also
   fixed in this pull request.

 - Additional LSM hook constification

   Two patches to constify parameters to security_capget() and
   security_binder_transfer_file(). While I generally don't make a
   special note of who submitted these patches, these were the work of
   an Outreachy intern, Khadija Kamran, and that makes me happy;
   hopefully it does the same for all of you reading this.

 - LSM hook comment header fixes

   One patch to add a missing hook comment header, one to fix a minor
   typo.

 - Remove an old, unused credential function declaration

   It wasn't clear to me who should pick this up, but it was trivial,
   obviously correct, and arguably the LSM layer has a vested interest
   in credentials so I merged it. Sadly I'm now noticing that despite my
   subject line cleanup I didn't cleanup the "unsued" misspelling, sigh

* tag 'lsm-pr-20230829' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm:
  lsm: constify the 'file' parameter in security_binder_transfer_file()
  lsm: constify the 'target' parameter in security_capget()
  lsm: add comment block for security_sk_classify_flow LSM hook
  security: Fix ret values doc for security_inode_init_security()
  cred: remove unsued extern declaration change_create_files_as()
  evm: Support multiple LSMs providing an xattr
  evm: Align evm_inode_init_security() definition with LSM infrastructure
  smack: Set the SMACK64TRANSMUTE xattr in smack_inode_init_security()
  security: Allow all LSMs to provide xattrs for inode_init_security hook
  lsm: fix typo in security_file_lock() comment header
