The next step is to use that we have cached the result of the matrix multiplication H * val in stoeplitz_cache_entry(scache, val), so the identity (H * x) ^ (H * y) == H * (x ^ y) allows us to push the calls to the cache function down to the end of stoeplitz_hash_ip{4,6}{,port}(). The identity in question was also confirmed on amd64, sparc64 and powerpc for all possible values of skey, x and y. ok dlg |

Now that the calls to stoeplitz_cache_entry() are out of the way, we can ditch half of the calculations by merging the computation of hi and lo, only splitting at the end. This allows us to leverage stoeplitz_hash_n16(). The name lo is now wrong. I kept it in order to avoid noise. I'm going to clean this up in the next step. ok dlg |

The same simplification can be done a second time: widen the type, xor laddr and faddr and the ports together and only then fold the 32 bits into 16 bits. ok dlg |

| message |
Compare `so' and `sosp' types just after `sosp' obtaining. We can't splice sockets from different domains so there is no reason to have locking and memory allocation in this error path. Also in this case only `so' will be locked by solock() so we should avoid `sosp' modification. ok mpi@ |

| message |
extend the bpf_hdr struct to include some metadata if available. the metadata is set if the mbuf is passed with an m_pktrhdr, and copies the mbufs rcvif, priority, flowid. it also carries the direction of the packet. it also makes bpf_hdr a multiple of 4 bytes, which simplifies some calculations a bit. it also requires no changes in userland because libpcap just thinks the extra bytes in the header are padding and skips over them to the payload. this helps me verify things like whether the stack and a network card agree about toeplitz hashes, and paves the way for doing more interesting packet captures. being able to see where a packet came from as it is leaving a machine is very useful. ok mpi@ |

pass the mbuf with the data separately to the one with the pkthdr to mtap. this lets things calling bpf_mtap_hdr and related functions also populate the extended bpf_hdr with the rcvif and prio and stuff. |
