netdevsim: Make nsim_num_vf static

2019-05-05T17:48:45Z

Fix sparse warning: drivers/net/netdevsim/bus.c:253:5: warning: symbol 'nsim_num_vf' was not declared. Should it be static? Reported-by: Hulk Robot Signed-off-by: YueHaibing Acked-by: Jakub Kicinski Signed-off-by: David S. Miller

netdevsim: fix fall-through annotation

2019-05-01T15:36:55Z

Replace "pass through" with a proper "fall through" annotation in order to fix the following warning: drivers/net/netdevsim/bus.c: In function ‘new_device_store’: drivers/net/netdevsim/bus.c:170:14: warning: this statement may fall through [-Wimplicit-fallthrough=] port_count = 1; ~~~~~~~~~~~^~~ drivers/net/netdevsim/bus.c:172:2: note: here case 2: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This fix is part of the ongoing efforts to enable -Wimplicit-fallthrough Signed-off-by: Gustavo A. R. Silva Acked-by: Jakub Kicinski Signed-off-by: David S. Miller

netdevsim: implement ndo_get_devlink_port

2019-04-26T05:52:03Z

Implement ndo_get_devlink_port and allow switch_id and port_name to be handled by devlink. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

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: extend device attrs to support port addition and deletion

2019-04-26T05:52:03Z

In order to test flows in core, it is beneficial to maintain previously supported possibility to add and delete ports during netdevsim lifetime. Do it by extending device sysfs attrs by "new_port" and "del_port". Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: implement dev probe/remove skeleton with port initialization

2019-04-26T05:52:02Z

Implement netdevsim bus probing of netdevsim devices. For every probed device create a devlink instance. According to the user-passed value, create a number of ports represented by devlink port instances. 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: generate random switch id instead of using dev id

2019-04-26T05:52:02Z

Current implementation of parent_id/switch_id does not follow the original idea of being unique. The values are "0", "1", etc. Instead of that, generate 32 random bytes. 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: rename dev_init/exit() functions and make them independent on ns

2019-04-26T05:52:02Z

These functions are going to be called from bus probe/release(), therefore make them independent on ns struct and rename accordingly. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller
