  • bb900b27a   bridge: allow creating bridge devices with netlink ... Browse Code »

    Add netlink device ops to allow creating bridge device via netlink.
    This works in a manner similar to vlan, macvlan and bonding.

    Example:
    # ip link add link dev br0 type bridge
    # ip link del dev br0

    The change required rearranging initializtion code to deal with
    being called by create link. Most of the initialization happens
    in br_dev_setup, but allocation of stats is done in ndo_init callback
    to deal with allocation failure. Sysfs setup has to wait until
    after the network device kobject is registered.

  • ab95bfe01   net: replace hooks in __netif_receive_skb V5 ... Browse Code »

    What this patch does is it removes two receive frame hooks (for bridge and for
    macvlan) from __netif_receive_skb. These are replaced them with a single
    hook for both. It only supports one hook per device because it makes no
    sense to do bridging and macvlan on the same device.

    Then a network driver (of virtual netdev like macvlan or bridge) can register
    an rx_handler for needed net device.

  • da6782927   bridge: Simplify interface for ATM LANE ... Browse Code »

    This patch changes FDB entry check for ATM LANE bridge integration.
    There's no point in holding a FDB entry around SKB building.

    br_fdb_get()/br_fdb_put() pair are changed into single br_fdb_test_addr()
    hook that checks if the addr has FDB entry pointing to other port
    to the one the request arrived on.

    FDB entry refcounting is removed as it's not used anywhere else.

  • d69efb168   bridge: kernel panic when unloading bridge module ... Browse Code »

    There is a race condition when unloading bridge and netfilter.

    The problem happens if __fake_rtable is in use by a skb
    coming in, while someone starts to unload bridge.ko.
    br_netfilter_fini() is called at the beginning of unload
    in br_deinit() while skbs still are being forwarded and
    transferred to local ip stack. Thus there is a possibility
    of the __fake_rtable pointer not being removed in a skb that
    goes up to ip stack. This results in a kernel panic, as
    ip_rcv() calls the input-function of __fake_rtable, which
    is NULL.

    Moving the call of br_netfilter_fini() to the end of
    br_deinit() solves the problem.

  • 11dc1f36a   [BRIDGE]: netlink interface for link management ... Browse Code »

    Add basic netlink support to the Ethernet bridge. Including:
    * dump interfaces in bridges
    * monitor link status changes
    * change state of bridge port

    For some demo programs see:
    http://developer.osdl.org/shemminger/prototypes/brnl.tar.gz

    These are to allow building a daemon that does alternative
    implementations of Spanning Tree Protocol.

  • 387e2b043   [BRIDGE]: need to ref count the LLC sap ... Browse Code »

    Bridge will OOPS on removal if other application has the SAP open.
    The bridge SAP might be shared with other usages, so need
    to do reference counting on module removal rather than explicit
    close/delete.

    Since packet might arrive after or during removal, need to clear
    the receive function handle, so LLC only hands it to user (if any).

  • cf0f02d04   [BRIDGE]: use llc for receiving STP packets ... Browse Code »

    Use LLC for the receive path of Spanning Tree Protocol packets.
    This allows link local multicast packets to be received by
    other protocols (if they care), and uses the existing LLC
    code to get STP packets back into bridge code.

    The bridge multicast address is also checked, so bridges using
    other link local multicast addresses are ignored. This allows
    for use of different multicast addresses to define separate STP
    domains.

    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!
