mnl: do not cache sender buffer size
SO_SNDBUF never fails, this socket option just provides a hint to the kernel. SO_SNDBUFFORCE sets the buffer size to zero if the value goes over INT_MAX. Userspace is caching the buffer hint that sends to the kernel, so it might leave userspace out of sync if the kernel ignores the hint. Do not make assumptions, fetch the sender buffer size from the kernel via getsockopt(). Signed-off-by: Pablo Neira Ayuso <>
