Description Raghavendra G 2009-09-01 05:21:29 UTC

The crash was due to glusterfs_glh_realpath assuming that the virtual mount point would be part of the content of symbolic link. It used to search for a vmp entry corresponding to the content of the symbolic link and it failed since symbolic link had only a relative path without vmp as part of it. And later in the code, this NULL vmp-entry was being dereferenced, causing the crash.
