netdevsim: add software driver for testing offloads To be able to run selftests without any hardware required we need a software model. The model can also serve as an example implementation for those implementing actual HW offloads. The dummy driver have previously been extended to test SR-IOV, but the general consensus seems to be against adding further features to it. Add a new driver for purposes of software modelling only. eBPF and SR-IOV will be added here shortly, others are invited to further extend the driver with their offload models.

netdevsim: implement couple of testing devlink health reporters Implement "empty" and "dummy" reporters. The first one is really simple and does nothing. The other one has debugfs files to trigger breakage and it is able to do recovery. The ops also implement dummy fmsg content. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

netdevsim: don't compile BPF code if syscall not enabled We should not compile netdevsim/bpf.c if BPF syscall is not enabled. Otherwise bpf core would have to provide wrappers for all functions offload drivers may call, even though system will never see a BPF object.

netdevsim: Add simple FIB resource controller via devlink 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.
