[GSoC'20 Weekly Update] Adding audit(4) support to NFS

[Shivank Garg]

Hi,

This project aims to add audit(4) support to NFS, which will allow
auditd(8) to just run on the NFS server and audit all activities within the
NFS network. Audit works mostly on the syscall level and NFS is implemented
within the kernel, which means the NFS RPCs don't generate any audit
records on the server.
Note that audit(4) can still be used on the NFS network but auditd(8) must
run on every NFS client.

This week I made the following progress:
* This week I completed the NFSAuditTestSuite for auditing all NFSv3 RPCs.
* NFSAuditTestSuite: https://github.com/shivankgarg98/NFSAuditTestSuite

Currently, I'm:
* improving the NFSv3 audit code in /sys for plausible bugs and making it
ready for the review.
