SO_LINGER gets processed by the Linux kernel generically here: http://lxr.free-electrons.com/source/net/core/sock.c#L644 with no check against socket type. The UDP socket handling doesn't use the resulting SOCK_LINGER flag setting. http://lxr.free-electrons.com/source/net/ipv4/udp.c http://lxr.free-electrons.com/source/net/ipv6/udp.c Only TCP and the Bluetooth SCO protocol in the Linux kernel care about SO_LINGER.
