mctp: Pass flow data & flow release events to drivers

2021-10-29T12:23:51+00:00

Now that we have an extension for MCTP data in skbs, populate the flow when a key has been created for the packet, and add a device driver operation to inform of flow destruction. Includes a fix for a warning with test builds: Reported-by: kernel test robot Signed-off-by: Jeremy Kerr Signed-off-by: David S. Miller

mctp: Add refcounts to mctp_dev

2021-09-29T10:00:11+00:00

Currently, we tie the struct mctp_dev lifetime to the underlying struct net_device, and hold/put that device as a proxy for a separate mctp_dev refcount. This works because we're not holding any references to the mctp_dev that are different from the netdev lifetime. In a future change we'll break that assumption though, as we'll need to hold mctp_dev references in a workqueue, which might live past the netdev unregister notification. In order to support that, this change introduces a refcount on the mctp_dev, currently taken by the net_device->mctp_ptr reference, and released on netdev unregister events. We can then use this for future references that might outlast the net device. Signed-off-by: Jeremy Kerr Signed-off-by: David S. Miller

mctp: Remove the repeated declaration

Function 'mctp_dev_get_rtnl' is declared twice, so remove the repeated declaration. Cc: Jeremy Kerr Cc: Matt Johnston Cc: "David S. Miller" Cc: Jakub Kicinski Signed-off-by: Shaokun Zhang Signed-off-by: David S. Miller

mctp: Add neighbour implementation

Add an initial neighbour table implementation, to be used in the route output path. Signed-off-by: Matt Johnston Signed-off-by: David S. Miller

mctp: Add device handling and netlink interface

2021-07-29T14:06:50+00:00

This change adds the infrastructure for managing MCTP netdevices; we add a pointer to the AF_MCTP-specific data to struct netdevice, and hook up the rtnetlink operations for adding and removing addresses. Includes changes from Matt Johnston . Signed-off-by: Jeremy Kerr Signed-off-by: David S. Miller
