Currently there is minimal checking beyond the basic read/write encoding. It needs to be extended ideally for each kind of descriptor and for each corresponding data structur and field that gets read from or written to. Linux does a much better job in this case. --=20 You are receiving this mail because: You are the assignee for the bug.=
