+++ This bug was initially created as a clone of Bug #1315557 +++
Description of problem:
GlusterFS 3.7 and earlier do not have support for the (new) SEEK FOP. There is no check in glfs_lseek() for unknown SEEK_* operations, this needs to be added
Version-Release number of selected component (if applicable):

Steps to Reproduce:

No error is returned.
-1 should get returned, and errno should have been set to EINVAL.

gfapi: return EINVAL for unsupported lseek() operations
GlusterFS 3.8 contains support for SEEK_DATA/SEEK_HOLE. This protocol
extension is not available in 3.6. libgfapi needs to handle unsupported
SEEK_* operations correctly, by returning -1 and setting errno to
This change is different from the patch in the master branch, it is only
needed to do the improved error checking in this version.

This bug is being closed as GlusterFS-3.6 is nearing its End-Of-Life and only important security bugs will be fixed. This bug has been fixed in more recent GlusterFS releases. If you still face this bug with the newer GlusterFS versions, please open a new bug.
In case glusterfs-3.6.10 gets released, the fix will be included automatically. It is highly recommended to use a newer glusterfs version.
