[Bug 173267] Re: Kernel ACL support for NFS/CIFS in 8.04?

[Axel Pospischil]

** Description changed:

  First: in my opinion this is NOT a duplicate of Bug #67175, because it
- affects the NEXT long term supported ubuntu. And it affects both the NFS
- and the CIFS(samba) network file system support of the ubuntu kernel. It
- is both, a bug for the actual gutsy and a wishlist/bug for hardy (8.04
- LTS).
+ affects the NEXT long term supported ubuntu. And it affects both the
+ NFSv3/v4 and the CIFS(samba) network file system support of the ubuntu
+ kernel and user tools (get/setfacl - nfs4-acl-tools, see [3]).
+ 
+ It is both, a bug for the former 6.06 LTS, the actual gutsy and a
+ wishlist/bug for hardy (8.04 LTS).
  
  I also asked for an answer here at lauchpad with Question #18907 (see
  links below [1]). Please refer this question for additional information.
- There are several similar post out there addressing the problem (see
- links below).
  
- I am not a kernel developer but I cannot understand where the problem is
- if major distributions (redhat/suse) seem to support nfs/cifs with acl
- out of the box - for about 2 years now (2005), right when ACL support
- came for SMB (see [4] page 133).

+ the tools exist.
  
  Because I consider this as a BUG concerning the ubuntu linux kernel
- flavour, and cannot find any comment/roadmap from the official side
- (canonical). I even don't see any effort being made on giving a solution
- to both client and server's side.

  [4] (see links below) gives a very excellent and detailed view of the
  actual state in NFS/CIFS linux development.
  
  Conclusion:
  
  1. With 8.04 LTS in mind there should be a clear statement concerning
  NFS/CIFS + ACL support in the kernel, so customers could decide - and
  ubuntu would like to address customers wishes, do they ;) One should not
  be forced to recompile the kernel and loose support.
  
  2. One also has to check/assure, that gnome, kde and xfce file managers
  are supporting mounted directories via nfs/smb/cifs and handle acl's
  properly.
  
  Sincerely yours Axel
