[Bug 1036647] Re: mount.cifs fails on mount DFS linked share


Jonathan Davies, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu server? ISO images are available from
http://cdimage.ubuntu.com/ubuntu-server/daily/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

  mount.cifs fails on mount DFS linked share

Status in “linux” package in Ubuntu:

Bug description:
  mount.cifs fails to mount a DFS linked share on 12.04, this behaviour
  worked fine on 10.04.

  The DFS structure is:


  Mounting running:

  $ sudo mount -t cifs //server1/TEST/SHARE-LINK /mnt/dfs-mount -o

  ..fails on a precise machine, while it works on lucid.

  My tests show that:

  10.04 | mount.cifs works on oneiric and precise kernels.
  12.04 | Stock kernel fails with both precise's mount.cifs and with lucid's mount.cifs compiled.
