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: change debugfs tree topology

2019-04-26T05:52:02Z

With the model where dev is represented by devlink and ports are represented by devlink ports, make debugfs file names independent on netdev names. Change the topology to the one illustrated by the following example: $ ls /sys/kernel/debug/netdevsim/ netdevsim1 $ ls /sys/kernel/debug/netdevsim/netdevsim1/ bpf_bind_accept bpf_bind_verifier_delay bpf_bound_progs ports $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/ 0 1 $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/ bpf_map_accept bpf_offloaded_id bpf_tc_accept bpf_tc_non_bound_accept bpf_xdpdrv_accept bpf_xdpoffload_accept dev ipsec $ ls /sys/kernel/debug/netdevsim/netdevsim1/ports/0/dev -l lrwxrwxrwx 1 root root 0 Apr 13 15:58 /sys/kernel/debug/netdevsim/netdevsim1/ports/0/dev -> ../../../netdevsim1 Signed-off-by: Jiri Pirko Signed-off-by: David S.

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 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

selftests/bpf: test reading the offloaded program

selftests/bpf: add test for mixing generic and offload XDP

2019-02-06T14:35:42Z

Add simple sanity check for enabling generic and offload XDP, simply reuse the native and offload checks. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

selftests/bpf: print traceback when test fails

2019-02-06T14:35:42Z

Figuring out which exact check in test_offload.py takes more time than it should. Print the traceback (to the screen and the logs). Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

selftests/bpf: fix the expected messages

2019-02-06T14:35:41Z

Recent changes added extack to program replacement path, expect extack instead of generic messages. Fixes: 01dde20ce04b ("xdp: Provide extack messages when prog attachment failed") Signed-off-by: Jakub Kicinski Signed-off-by: Daniel Borkmann

selftests/bpf: add test for sharing objects between netdevs

2018-07-18T13:10:34Z

Add tests for sharing programs and maps between different netdevs. Use netdevsim's ability to pretend multiple netdevs belong to the same "ASIC". Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: associate bound programs with shared dev

2018-07-18T13:10:33Z

Move bound program information from netdevsim to shared sub-object, as programs will soon be shared between netdevs of the same ASIC. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann
