            Bug ID: 1403612
           Summary: With NFS root-squash the other x-bit has to be set to
                    make dirs
           Product: GlusterFS
           Version: 3.7.17
         Component: nfs
          Severity: high
          Assignee: bugs at gluster.org
          Reporter: happe at nbi.dk
                CC: bugs at gluster.org



Description of problem:

Using NFS client and server.root-squash=on, directory creation is not allowed
unless the others x-bit is set (chmod o+x). With the FUSE client it works as
expected.  

Version-Release number of selected component (if applicable):

CentOS 6.8 (client and server).
GlusterFS from SIG.
3.7.13 did not have this problem.

How reproducible:

Every time.

Steps to Reproduce:
1. Set server.root-squash to on.
2. Mount with NFS client. 
3. Create dir without other x-bit (chmod o-x).
4. Try to create another dir in the dir => Not permitted.

Actual results:

[hhh at client foo]$ ls -la
total 8
drwxr-x--- 2 hhh others 4096 Dec 11 23:00 .
drwxrwx--x 3 hhh others 4096 Dec 11 22:56 ..
[hhh at client foo]$ mkdir bar
mkdir: cannot create directory `bar': Permission denied

Expected results:

[hhh at client foo]$ mkdir bar
[hhh at client foo]$ ls -l
total 4
drwxr-xr-x 2 hhh others 4096 Dec 11 23:22 bar


Additional info:

It is possible to create files.
When server.root-squash is off it works.
FUSE client works.
