netdevsim: change fib accounting and limitations to be per-device

2019-10-04T18:10:55+00:00

Currently, the accounting is done per-namespace. However, devlink instance is always in init_net namespace for now, so only the accounting related to init_net is used. Limitations set using devlink resources are only considered for init_net. nsim_devlink_net() always returns init_net always. Make the accounting per-device. This brings no functional change. Per-device accounting has the same values as per-net. For a single netdevsim instance, the behaviour is exactly the same as before. When multiple netdevsim instances are created, each can have different limits. This is in prepare to implement proper devlink netns support. After that, the devlink instance which would exist in particular netns would account and limit that netns. Signed-off-by: Jiri Pirko Acked-by: Jakub Kicinski Signed-off-by: David S. Miller

netdevsim: Restore per-network namespace accounting for fib entries

2019-08-12T03:59:19+00:00

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

drivers: net: use flow block API

2019-07-09T21:38:50+00:00

This patch updates flow_block_cb_setup_simple() to use the flow block API. Several drivers are also adjusted to use it. This patch introduces the per-driver list of flow blocks to account for blocks that are already in use. Remove tc_block_offload alias. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: add flow_block_cb_setup_simple()

2019-07-09T21:38:50+00:00

Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.

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
