When I do a setsockopt(..,SO_RCVBUF,..) and then read the value back
with getsockopt(), the reported value is exactly twice of what I set.
Running the same code on Solaris and on DEC UNIX reports back the
exact size I set.
Looking at the code it seems that the *2 should not be there:
>From /usr/src/linux/net/core/sock.c:
int sock_setsockopt(...
case SO_SNDBUF:
sk->sndbuf = max(val*2,SOCK_MIN_SNDBUF);
case SO_RCVBUF:
/* FIXME: is this lower bound the right one? */
sk->rcvbuf = max(val*2,SOCK_MIN_RCVBUF);
break;
