FreeBSD src repository
Modified files:
sys/net bpf.h
sys/sys mbuf.h
Log:
Add a new macro M_ASSERTVALID which ensures that the mbuf in question
is non-free. (More checks can/should be added in the future.)
Use M_ASSERTVALID in BPF_MTAP so that we catch when freed mbufs are
passed in, even if no bpf listeners are active.
Inspired by a bug in if_dc caught by Kenjiro Cho.
