[Gluster-devel] posix: symlink broken?

[M. Mohan Kumar]

As part of BD xlator symlink interface testing, I figured out that the
parameter 'linkname' contains even the mount point for example
'/media/link'. I wonder we should never get the mount directory in the
server part of code.

I tested creating symlink with posix xlator with top git commit
751da4675cf3add21e567aebb92de2c10457afee.

Here is the steps I followed:

address@hidden mohan]# mount -t glusterfs host:/posix /media

address@hidden mohan]# ls -la /media/
total 8
drwx------.  3 root root 4096 Oct 11 11:15 .
dr-xr-xr-x. 20 root root 4096 Sep 28 16:40 ..

address@hidden mohan]# touch /media/file

address@hidden mohan]# ln -s /media/file /media/link

address@hidden mohan]# ls -la /media/
total 9
drwx------.  3 root root 4096 Oct 11 11:18 .
dr-xr-xr-x. 20 root root 4096 Sep 28 16:40 ..
-rw-r--r--.  1 root root    0 Oct 11 11:18 file
lrwxrwxrwx.  1 root root   11 Oct 11 11:18 link -> /media/file

address@hidden mohan]# umount /media

address@hidden mohan]# mount -t glusterfs host:/posix /media/posix

address@hidden mohan]# ls -la /media/posix/
total 9
drwx------. 3 root root 4096 Oct 11 11:18 .
drwxr-xr-x. 4 root root 4096 Oct 11 07:55 ..
-rw-r--r--. 1 root root    0 Oct 11 11:18 file
lrwxrwxrwx. 1 root root   11 Oct 11 11:18 link -> /media/file


Directory listing of brick from server side
address@hidden mohan]# ls -la ~/gl/posix/
total 24
drwx------.  3 root root 4096 Oct 11 11:18 .
drwx------.  4 root root 4096 Sep 28 20:20 ..
-rw-r--r--.  2 root root    0 Oct 11 11:18 file
drw-------. 12 root root 4096 Oct 11 11:18 .glusterfs
lrwxrwxrwx.  2 root root   11 Oct 11 11:18 link -> /media/file


Ideally it should be link -> file instead of /media/file
 
When I remounted with a different directory symlink is broken. Ideally
it should not create symlink with client mount directory details or am I
missing some thing here?
