Hi, In FreeBSD icmp6 code I see function where we are either going to freeit where passed mbuf is freed or we are simply returning. For example: icmp6_input calls icmp6_redirect_input and right after it returns it makes m=NULL. Inside icmp6_redirect_input there are checks for ifp and for the message being short (which probably don't get exercised that often (or at all?)) and for these checks simply return. Looks to be mbuf leak. In other icmp6 functions also we have similar instances. Just wanted to check if these are there undetected or not. This is my first mail to the BSD community so I am not sure if reporting this in the mail the right way. Please let me know. Best, Prabhakar
