Most fscrypt-enabled filesystems store the crypto context in an xattr, but that's problematic for ceph as xatts are governed by the XATTR cap, but we really want the crypto context as part of the AUTH cap. Because of this, the MDS has added two new inode metadata fields: fscrypt_auth and fscrypt_file. The former is used to hold the crypto context, and the latter is used to track the real file size. Parse new fscrypt_auth and fscrypt_file fields in inode traces. For now, we don't use fscrypt_file, but fscrypt_auth is used to hold the fscrypt context. Allow the client to use a setattr request for setting the fscrypt_auth field. Since this is not a standard setattr request from the VFS, we add a new field to __ceph_setattr that carries ceph-specific inode attrs. Have the set_context op do a setattr that sets the fscrypt_auth value, and get_context just return the contents of that field (since it should always be available).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
