Lustre has a 'squash credentials' concept similar to the "anon_uid" for nfsd. When accessing a file with squashed credentials, we need to also drop capabilities. Linux has cap_drop_fs_set() and cap_drop_nfsd_set(). Rather than taking a completely different approach, this patch changes lustre to use this same cap_drop_*_set() approach. With this change we also drop CAP_MKNOD and CAP_MAC_OVERRIDE which are probably appropriate, and don't drop CAP_SYS_ADMIN or CAP_SYS_BOOT which should be irrelevant for file permission checking Calling both cap_drop_*_set() seems a bit clumsy, but gets the job done.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
