glusterd: Buffer overflow causing crash for glusterd
Backport of http://review.gluster.org/11090
Problem: In GLUSTERD_GET_DEFRAG_PROCESS we are using PATH_MAX (4096)
as the max size of the input for target path, but we have allocated
NAME_MAX (255) size of buffer for the target.
Now this crash is not seen with source, but seen with RPMS.
The reason is _foritfy_fail. This check happens when _FORTIFY_SOURCE
is enabled. This option tries to figure out possible
overflow scenarios like the bug here and does crash the process.
BUG: 1227677
