access.W_OK yields -1 EACCES (permission denied) on NFS mountpoints
Status in linux package in Ubuntu:

Bug description:
When upgrading from xenial kernel (4.4.0-145) to linux-image-generic-
hwe-16.04 (4.15.0-47) I am no longer able to run an application that
checks it's data directory for write access/path traversal when that
directory is an NFS share. This works on 4.4 and 3.13 kernels that I
tested with but fails on 4.15. I'm using NFSv3 and have seen the
behavior with both a synology NAS as the nfs-server as well as my
xenial desktop as the nfs-server.
To reproduce:
0.) Boot test machine with kernel 4.15.0-47
1.) set up a NFS export on another machine (nfs-server)
/etc/exports:
/srv/nfstest 192.168.100.100(rw,sync,no_subtree_check)
2.) mount the NFS share on the test machine and give a non-root user
ownership of the mount, in my case I have a user: aptly, with
home=/var/lib/aptly, and I mounted the NFS at /var/lib/aptly/test.
aptly:aptly owns /var/lib/aptly/test.
/etc/fstab:
192.168.100.101:/srv/nfstest/var/lib/aptly/test nfs rw,mountvers=3
3.) attempt to call access.W_OK on the mount as the non-root user `strace
./testaccess.py`

To reproduce:
0.) Boot test machine with kernel 4.15.0-47
1.) set up a NFS export on another machine (nfs-server)
/etc/exports:
/srv/nfstest 192.168.100.100(rw,sync,no_subtree_check)
2.) mount the NFS share on the test machine and give a non-root user
ownership of the mount, in my case I have a user: aptly, with
home=/var/lib/aptly, and I mounted the NFS at /var/lib/aptly/test.
aptly:aptly owns /var/lib/aptly/test.
/etc/fstab:
192.168.100.101:/srv/nfstest/var/lib/aptly/test nfs rw,mountvers=3
3.) attempt to call access.W_OK on the mount as the non-root user `strace
./testaccess.py`

hwe-16.04 (4.15.0-47) I am no longer able to run an application that
checks it's data directory for write access/path traversal when that
directory is an NFS share. This works on 4.4 and 3.13 kernels that I
tested with but fails on 4.15. I'm using NFSv3 and have seen the
behavior with both a synology NAS as the nfs-server as well as my
xenial desktop as the nfs-server.
To reproduce:
0.) Boot test machine with kernel 4.15.0-47
1.) set up a NFS export on another machine (nfs-server)
/etc/exports:
/srv/nfstest 192.168.100.100(rw,sync,no_subtree_check)
2.) mount the NFS share on the test machine and give a non-root user
ownership of the mount, in my case I have a user: aptly, with
home=/var/lib/aptly, and I mounted the NFS at /var/lib/aptly/test.
aptly:aptly owns /var/lib/aptly/test.
/etc/fstab:
192.168.100.101:/srv/nfstest/var/lib/aptly/test nfs rw,mountvers=3
3.) attempt to call access.W_OK on the mount as the non-root user `strace
./testaccess.py`
stderr:
...
access("/var/lib/aptly/test", W_OK) = -1 EACCES (Permission denied)
...
stdout:
('Writeable:', False)
