Title:
  NFS client : permission denied when trying to access subshare, since
  kernel 4.4.0-31

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Committed
Status in linux source package in Yakkety:
  Fix Committed

Bug description:
  SRU Justification

  Impact: A regression has caused mounting of NFS subshares with
  kerberos authentication to fail. This is a result of
  follow_automount() overriding the user credentials before calling
  dentry->d_automount().

  Fix: Cherry pick from linux-next.

  Regression Potential: The commit fixes a regression and makes the
  automount behavior more like it was prior to changes in 4.8 (which we
  also backported to xenial). Therefore the regression potential should
  be minimal.

  Similar like Bug #1603719 or Bug #1604396 i got a "Permission denied"
  when trying to access a NFS subshare from our NFSv4 Server.

  I tried this under (K)ubuntu Trusty and Xenial and also with the
  ubuntu based Mint Versions 17.3 Rosa an 18 Sarah.

  Kernel Versions higher than 4.4.0-31 from offical Ubuntu Repository has the problem.
  Before 4.4.0-31 not. For safety reasons i used the linux-generic-lts-wily meta package

  The 4.4 mainline kernel also works without problem currently
  (4.4.37-040437-generic)

  Our NFS server runs under FreeBSD 11, but same problems to the clients
  with FreeBSD 10.3 and OmniOS r151018.

  All NFS servers use ZFS as the filesystem and NFSv4 with kerberos for
  sharing. For the basic structure we use  also ZFS filesystems.

  So my homefolder is located on the server under
  /apool/AIS/share/home/staff/fili/linux ... each level is a ZFS
  filesystem. On the client nfs share /apool/AIS/share/home is mounted
  under /home/VI

  My posix homedirectory path is /home/VI/staff/fili/linux

  When i try to login i got access to /home/VI/staff/fili ... but when i
  try to access the linux directory / zfs filesystem i got the
  permission denied.

  The fstab options for /home/VI are
  _netdev,rw,sync,sec=krb5,nfsvers=4,clientaddr=w.x.y.z

  I tried also autofs but with the same result.
