Robert Watson e82669d99b When resetting a BPF descriptor, properly check that zero-copy buffers ... are not currently owned by userspace before clearing or rotating them. Otherwise we may not play by the rules of the shared memory protocol, potentially corrupting packet data or causing userspace applications that are playing by the rules to spin due to being notified that a buffer is complete but the shared memory header not reflecting that. This behavior was seen with pflogd by a number of reporters; note that this fix is not sufficient to get pflogd properly working with zero-copy BPF, due to pflogd opening the BPF device before forking, leading to the shared memory buffer not being propery inherited in the privilege-separated child. We're still deciding how to fix that problem. This change exposes buffer-model specific strategy information in reset_d(), which will be fixed at a later date once we've decided how best to improve the BPF buffer abstraction.
