And there is en[namelen] = '\0', should fix namelen to its right value.

Double free problem:
Since ddr bit jump makes i_namelen a larger value (> 255)，when file is
not encrypted,
the convert_encrypted_name will memcpy out range of en[255], when en is
freed, there
will be double free problem.
It looks there is only memcpy overflow problem here.

There is no commit log, so what do you mean about "avoid double free"?
Other than that, looks good to me.
