Thus if you call getsockopt to find the current value, change it and then attempt to restore the old value you will double the old value. The setsockopt SO_RCVBUF code in net/core/sock.c:291 is doubling the passed in value. sk->sk_rcvbuf = val * 2; But the getsockopt SO_RCVBUF code in net/core/sock.c:495 does not halve it. case SO_RCVBUF: v.val = sk->sk_rcvbuf; Either the set code should not double val or the get code should halve for consistency. If this is deliberate a comment would be useful to explain why.
