  • 80feaacb8   [AF_PACKET]: Add option to return orig_dev to userspace. ... Browse Code »

    Add a packet socket option to allow the orig_dev index to be returned
    to userspace when passing traffic through a decapsulated device, such
    as the bonding driver.

    This is very useful for layer 2 traffic being able to report which
    physical device actually received the traffic, instead of having the
    encapsulating device hide that information.

    The new option is called PACKET_ORIGDEV.

  • 8dc419447   [PACKET]: Add optional checksum computation for recvmsg ... Browse Code »

    This patch is needed to make ISC's DHCP server (and probably other
    DHCP servers/clients using AF_PACKET) to be able to serve another
    client on the same Xen host.

    The problem is that packets between different domains on the same
    Xen host only have partial checksums. Unfortunately this piece of
    information is not passed along in AF_PACKET unless you're using
    the mmap interface. Since dhcpd doesn't support packet-mmap, UDP
    packets from the same host come out with apparently bogus checksums.

    This patch adds a mechanism for AF_PACKET recvmsg(2) to return the
    status along with the packet. It does so by adding a new cmsg that
    contains this information along with some other relevant data such
    as the original packet length.

    I didn't include the time stamp information since there is already
    a cmsg for that.

    This patch also changes the mmap code to set the CSUMNOTREADY flag
    on all packets instead of just outoing packets on cooked sockets.

    Weirdness: the third argument of socket() is net-endian
    here. Oh, well - it's documented in packet(7).

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
