netdevsim: Restore per-network namespace accounting for fib entries

2019-08-25T14:10:38+00:00

[ Upstream commit 59c84b9fcf42c99a945d5fdc49220d854e539690 ] Prior to the commit in the fixes tag, the resource controller in netdevsim tracked fib entries and rules per network namespace. Restore that behavior. Fixes: 5fc494225c1e ("netdevsim: create devlink instance per netdevsim instance") Signed-off-by: David Ahern Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

netdevsim: implement ndo_get_devlink_port

2019-04-26T05:52:03+00:00

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

2019-04-26T05:52:03+00:00

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: implement dev probe/remove skeleton with port initialization

2019-04-26T05:52:02+00:00

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

2019-04-26T05:52:02+00:00

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

2019-04-26T05:52:02+00:00

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

2019-04-26T05:52:02+00:00

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

2019-04-26T05:52:02+00:00

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

netdevsim: add bus attributes to add new and delete devices

2019-04-26T05:52:02+00:00

Add a way to add new netdevsim device on netdevsim bus and also to delete existing netdevsim device from the bus. Track the bus devices in using a list. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

netdevsim: move device registration and related code to bus.c

2019-04-26T05:52:02+00:00

Move netdevsim device registration into bus.c and alongside with that the related sysfs attributes. Introduce new struct nsim_bus_dev to represent a netdevsim device on netdevsim bus. Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller
