netdevsim: Implement ndo_get_port_parent_id()

2019-02-06T22:17:03Z

netdevsim only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a great candidate to be converted to use the ndo_get_port_parent_id() NDO instead of implementing switchdev_port_attr_get(). Acked-by: Jiri Pirko Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

netdevsim: make debug dirs' dentries static

2018-07-27T04:28:54Z

The root directories of netdevsim should only be used by the core to create per-device subdirectories, so limit their visibility to the core file. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: David S. Miller

netdevsim: add shared netdevsim devices

2018-07-18T13:10:33Z

Factor out sharable netdevsim sub-object and use IFLA_LINK to link netdevsims together at creation time. Sharable object will have its own DebugFS directory. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add switch_id attribute

2018-07-18T13:10:33Z

Grouping netdevsim devices into "ASICs" will soon be supported. Add switch_id attribute to all netdevsims. For now each netdevsim will have its switch_id matching the device id. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add support for simultaneous driver and hw XDP

Allow netdevsim to accept driver and offload attachment of XDP BPF programs at the same time. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add ipsec offload testing

net: sched: pass extack pointer to block binds and cb registration

2018-06-26T14:21:32Z

Pass the extact struct from a tc qdisc add to the block bind function and, in turn, to the setup_tc ndo of binding device via the tc_block_offload struct. Pass this back to any block callback registrations to allow netlink logging of fails in the bind process.

netdevsim: Change nsim_devlink_setup to return error to caller

netdevsim: Add simple FIB resource controller via devlink

2018-03-29T18:10:31Z

Add devlink support to netdevsim and use it to implement a simple, profile based resource controller. Only one controller is needed per namespace, so the first netdevsim netdevice in a namespace registers with devlink. If that device is deleted, the resource settings are deleted. The resource controller allows a user to limit the number of IPv4 and IPv6 FIB entries and FIB rules. The resource paths are: /IPv4 /IPv4/fib /IPv4/fib-rules /IPv6 /IPv6/fib /IPv6/fib-rules The IPv4 and IPv6 top level resources are unlimited in size and can not be changed. From there, the number of FIB entries and FIB rule entries are unlimited by default. A user can specify a limit for the fib and fib-rules resources: $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib size 96 $ devlink resource set netdevsim/netdevsim0 path /IPv4/fib-rules size 16 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib size 64 $ devlink resource set netdevsim/netdevsim0 path /IPv6/fib-rules size 16 $ devlink dev reload netdevsim/netdevsim0 such that the number of rules or routes is limited (96 ipv4 routes in the example above): $ for n in $(seq 1 32); do ip ro add 10.99.$n.0/24 dev eth1; done Error: netdevsim: Exceeded number of supported fib entries. $ devlink resource show netdevsim/netdevsim0 netdevsim/netdevsim0: name IPv4 size unlimited unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables non resources: name fib size 96 occ 96 unit entry size_min 0 size_max unlimited size_gran 1 dpipe_tables ... With this template in place for resource management, it is fairly trivial to extend and shows one way to implement a simple counter based resource controller typical of network profiles. Currently, devlink only supports initial namespace. Code is in place to adapt netdevsim to a per namespace controller once the network namespace issues are resolved.
