Hi, for me the proposed kernel 4.4.0-46.67 do not work ... Permission denied ...
As mentioned above mainline 4.4.27 work without problem. Maybe some surveillance will help. In our enviroment the FreeBSD 11 server shares /apool/NFS/share/home as NFSv4 + Kerberos ... every directory is a zfs filesystem. The clients mount /home/nfs. Users home is located under /home/nfs/staff/username ... staff and username are also zfs filesystems. A user can accesss his homedirectory under /home/nfs/staff/username without error but the next level deeper will only work as a normal directory, not as another zfs filesystem or NFSv4 sub-share If i look at the mounts as the affected user with mount or df i see the base mountpoint /home/nfs and the sub-shares /home/nfs/staff and /home/nfs/staff/username With kernels having the problem, the next sub-share will not shown when i try to access it. With kernel working without the "Permission denied" problem i am able to access the next sub-share (data for example ) and mount or df shows also /home/nfs/staff/username/data This happend also on shares without kerberos. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1604396 Title: Kernel 4.4.0-31 cd into NFS4 directory: Operation not permitted Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Bug description: Since apt-upgrading my Ubuntu 16.04 PC to kernel 4.4.0-31 I can't cd into NFS4 subvolumes any more: zierke@rzpc100$ uname -a Linux rzpc100 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux zierke@rzpc100$ kinit Password for zie...@informatik.uni-hamburg.de: zierke@rzpc100$ cd /informatik2 zierke@rzpc100$ cd rz -bash: cd: /informatik2/rz: Operation not permitted When I reboot my PC with the previous kernel 4.4.0-28 this works fine.
