There were two remaining "gaps" in auditing local bridge traffic with bpf(4): Locally originated outbound traffic from a member interface is invisible to the bridge's bpf(4) interface. Inbound traffic locally destined to a member interface is invisible to the member's bpf(4) interface -- this traffic has no chance after bridge_input to otherwise pass it over, and it wasn't originally received on this interface. I call these "gaps" because they don't affect conventional bridge setups. Alas, being able to establish an audit trail of all locally destined traffic for setups that can function like this is useful in some scenarios.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
