Hm, sorry i hope there was no misunderstanding ?! As i mentioned some times before, there was a strange behaviour when i test the kernels the first time. Sometimes a kernel boot successfully for one or two times and crash not before the third try ... I could reproduce this behaviour on different computers, but at the beginning of the tests i declare kernel would be ok by mistake this way. Maybe someone else are able to explain such a behaviour ... When i tested the kernels the second time, i try to boot every kernel three time to ensure getting the correct tag.

@Seth : Yes, this problem is very confusing Since posting #8 i used a dedicated test system with a fresh kubuntu 16.04.1 installation on a well tested system. During the testing i modify /etc/fstab switching between noauto/auto options of nfs shares and later changing server uri to ip address or adding new entries from other servers. And i install the test kernels, of course ;) Today i install the commit 50f208e18014589971583a8495987194724d56e4 again ... and it crashes as i said before. Unfortunately the kernel 4.4.0-54 is not available any longer from offical repos ... so i not able to test this one again ... but maybe this kernel had also the problem ?! At the beginning i was very confused because of some kernel crashes ... not on the first try but on the second or third try.

Sorry, the same behavior. But i found something else... It is very frustrating, to be apparent the only one having this problem, so i try to setup a nfsv4 server on Ubuntu (14.04.5 with linux-generic-lts-wily kernel 4.2.0-42) /etc/exports: /home/exports *(rw,fsid=0,crossmnt,no_subtree_check,sync) /home/exports/user *(rw,nohide,insecure,no_subtree_check,sync) /home/exports/staff *(rw,nohide,insecure,no_subtree_check,sync) Client (Ubuntu 16.04.1) /etc/fstab server:/user /home/server/user nfs _netdev,auto,rw,noatime,nfsvers=4,sync 0 0 server:/staff /home/server/staff nfs _netdev,auto,rw,noatime,nfsvers=4,sync 0 0 mount -a or command line mount works without problem ... --- The behavior is not exactly the same as in our enviorment with a FreeBSD Server but similar i think.

I tested something else ... Now i change only the group permissions ( chgrp staff and chmod 750 ... but the result is the same. Fristlevel subshare with the need of checking permissions will work, the second level subshare not. By the way ... one reason why we use a Solaris Fork or FreeBSD as a NFSv4 fileserver is the possibility of using NFS4-ACLs. So when i change the trivial permissions on the fileserver with chmod the NFS4-ACLs also modified. and on the client those permission are also active. Maybe the problem is in the part of the NFS4-ACLs.

apport information ** Tags added: apport-collected xenial ** Description changed: 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.

Very strange ... for us the problem is not solved ... all Kernel Versions for Trusty and Xenial since 4.4.0-31-generic are affected ... 4.4.0-54 also. Through the report here and Bug #1604396 i tested some mainline kernel ... By todays post the latest 4.4 mainline kernel ( 4.4.37-040437-generic )work for us without problems But 4.8 and 4.9 kernel have still the access denied error for NFS subshares -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1603719 Title: [regression] NFS client: access problems after updating to kernel 4.4.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1604396] Re: Kernel 4.4.0-31 cd into NFS4 directory: Operation not permitted
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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604396 Title: Kernel 4.4.0-31 cd into NFS4 directory: Operation not permitted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1604396/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
