bpf, xdp: Remove XDP_QUERY_PROG and XDP_QUERY_PROG_HW XDP commands

2020-07-26T03:37:02Z

Now that BPF program/link management is centralized in generic net_device code, kernel code never queries program id from drivers, so XDP_QUERY_PROG/XDP_QUERY_PROG_HW commands are unnecessary. This patch removes all the implementations of those commands in kernel, along the xdp_attachment_query(). This patch was compile-tested on allyesconfig.

netdevsim: use IS_ERR instead of IS_ERR_OR_NULL for debugfs

2020-02-03T23:32:20Z

Debugfs APIs return valid pointer or error pointer. it doesn't return NULL. So, using IS_ERR is enough, not using IS_ERR_OR_NULL. Reviewed-by: Jakub Kicinski Reported-by: kbuild test robot Reported-by: Dan Carpenter Signed-off-by: Taehee Yoo Signed-off-by: Jakub Kicinski

netdevsim: move netdev creation/destruction to dev probe

2019-04-26T05:52:03Z

Remove the existing way to create netdevsim over rtnetlink and move the netdev creation/destruction to dev probe, so for every probed port, a netdevsim-netdev instance is created. Adjust selftests to work with new interface. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: merge sdev into dev

2019-04-26T05:52:02Z

As previously introduce dev which is mapped 1:1 to a bus device covers the purpose of the original shared device, merge the sdev code into dev. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: move sdev-specific init/uninit code into separate functions

In order to improve readability and prepare for future code changes, move sdev specific init/uninit code into separate functions. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: make bpf_offload_dev_create() per-sdev instead of first ns

2019-04-12T23:49:54Z

offload dev is stored in sdev struct. However, first netdevsim instance is used as a priv. Change this to be sdev to as it is shared among multiple netdevsim instances. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: move sdev specific bpf debugfs files to sdev dir

2019-04-12T23:49:54Z

Some netdevsim bpf debugfs files are per-sdev, yet they are defined per netdevsim instance. Move them under sdev directory. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

bpf: offload: add priv field for drivers

2019-02-12T16:07:09Z

Currently bpf_offload_dev does not have any priv pointer, forcing the drivers to work backwards from the netdev in program metadata. This is not great given programs are conceptually associated with the offload device, and it means one or two unnecessary deferences. Add a priv pointer to bpf_offload_dev.
