Fix port leaking after controlling_process(Port, self())
Add case to handle the situation when someone call
{gen_tcp,gen_udp}:controlling_process(Port, self()). Also improve spec
and doc from gen_udp and gen_sctp for controlling_process/2.
To reproduce the issue, open an UDP port:
4> {ok,Port} = gen_udp:open(9000, [binary]).
{ok,#Port<0.587>}
5> gen_udp:controlling_process(Port, self()).
ok
Simulate error:
6> 1=2.
** exception error: no match of right hand side value 2
Here is the leak:
7> inet:i().
Port Module Recv Sent Owner Local Address Foreign Address State
Type
581 inet_udp 0 0 <0.31.0> *:cslistener *:* BOUND
DGRAM
ok
