Re: [PATCH] Basic support for checking NFSv4 ACLs in Linux

[Bruno Haible]

Hi Ondrej,

Thanks for the proposed patch.

But before we go into details, I would like to understand the big picture:

  1) What is the scenario in which the patch should make a difference?
     An NFSv4 volume exported from a different machine, and mounted on Linux,
     right?
     Which OSes are supported for the exporting machine?
     Which configurations need to be applied on the exporting machine?
     Which mount options need to be used on the Linux machine?

  2) When I look at the acl-2.3.1 source code [1], I get the impression that
     the Linux kernel exports the ACL attributes also for NFS. Is this true?
     To which extend does the 'acl' package support NFSv4 ACLs? To which
     extent do the maintainers of this package plan to do so?
