USS : fill proper uid and gid during a access call from nfs
Problem : when an user tries to access a file/folder for which he does not have a proper permission required then fuse gives out a proper error "Permission denied", but nfs does not give out that error, rather he can access the file/folder. The reason being uid and gid of call frame stack takes a default value of uid and gid which point to root permission. Solution : Set a proper uid and gid during a access call from nfs Change-Id: Ib060706fde66ec7e60f242fab1f3e59122ed2245 BUG: 1167580 Signed-off-by: Sachin Pandit <spandit@redhat.com> Reviewed-on: http://review.gluster.org/9194 Reviewed-by: Vijaikumar Mallikarjuna <vmallika@redhat.com> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
