[PATCH v2 0/9] pynfs tests for setting ACL+MODE

[Chuck Lever <cel@kernel.org>]

From: Chuck Lever <chuck.lever@oracle.com>

There are plenty of corner cases when an NFSv4 client requests
setting an NFSv4 ACL and POSIX mode bits in the a single SETATTR
request. It's even worse for NFS server implementations that have
to translate NFSv4 ACLs to POSIX ACLs.

Note that the in-kernel Linux NFS client itself does not support 
NFSv4 ACLs since Linux is a POSIX ACL ecosystem. I believe it will
never send an OPEN(create) or SETATTR that sets an NFSv4 ACL and
mode bits simultaneously, relying on only user space tooling to set
the ACL. So we must depend on only pynfs for testing this particular
NFSD facility.

pynfs didn't have many tests in this particular category when I set
out to troubleshoot a recently reported ACL+MODE bug in NFSD. So
I've written a handful to exercise this specific case.

Changes since RFC:
* De-duplicate code shared between NFSv4.0 and NFSv4.1
* Remove named principals tests for now
* Replace incorrect usage of binary strings
* Add missing patch descriptions
