[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. It is both, a bug for the
  former 6.06 LTS, the actual gutsy and a wishlist/bug for hardy (8.04
  LTS).
  
  It affects both the lacking NFSv3/v4 and the SMB(2)/CIFS network file
  system support for ACL's of the ubuntu kernel and user tools. E.g.
  accordingly patched get/setfacl, lacking of nfs4-acl-tools (see [3]) and
  not compiled NFSv3 ACL support in the generic kernel.
  
  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). So the kernel support must be
  mature and the user tools exist.
  
  I consider this as a BUG concerning the "ubuntu linux kernel" flavour
  and "user tools" and cannot find any comment/roadmap from official side
  (canonical) - except [3] - on giving a solution to both client and
  server's side.
  
  I also asked for an answer here at lauchpad with Question #18907 (see
- links below [1]) and Bug #173324 (Will nfs4-acl-tools be in 8.04?).
- Please refer this for additional information. .
+ links below [1]) and Bug #173324 (Will nfs4-acl-tools be in 8.04? -
+ [update] converted into Question #19120 see [7]). Please refer this for
+ additional information.
  
  Conclusion:
  
  1. With 8.04 LTS in mind there should be a clear statement concerning
  NFS/SMB(2)/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
