netdevsim: Add debugfs toggle to reject BPF programs in verifier

2020-12-09T15:27:42Z

This adds a new debugfs toggle ('bpf_bind_verifier_accept') that can be used to make netdevsim reject BPF programs from being accepted by the verifier. If this toggle (which defaults to true) is set to false, nsim_bpf_verify_insn() will return EOPNOTSUPP on the last instruction (after outputting the 'Hello from netdevsim' verifier message). This makes it possible to check the verification callback in the driver from test_offload.py in selftests, since the verifier now clears the verifier log on a successful load, hiding the message from the driver.

netdevsim: shared UDP tunnel port table support

2020-09-28T19:50:12Z

Add the ability to simulate a device with a shared UDP tunnel port table. Try to reject the configurations and actions which are not supported by the core, so we don't get syzcaller etc. warning reports. Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

netdevsim: add support for flash_update overwrite mask

2020-09-26T00:20:57Z

The devlink interface recently gained support for a new "overwrite mask" parameter that allows specifying how various sub-sections of a flash component are modified when updating. Add support for this to netdevsim, to enable easily testing the interface. Make the allowed overwrite mask values controllable via a debugfs parameter. This enables testing a flow where the driver rejects an unsupportable overwrite mask. Signed-off-by: Jacob Keller Reviewed-by: Jakub Kicinski Signed-off-by: David S. Miller

bpf, xdp: Remove XDP_QUERY_PROG and XDP_QUERY_PROG_HW XDP commands

2020-07-26T03:37:02Z

Now that BPF program/link management is centralized in generic net_device code, kernel code never queries program id from drivers, so XDP_QUERY_PROG/XDP_QUERY_PROG_HW commands are unnecessary. This patch removes all the implementations of those commands in kernel, along the xdp_attachment_query(). This patch was compile-tested on allyesconfig.

netdevsim: Add support for setting of packet trap group parameters

2020-03-31T00:54:58Z

Add a dummy callback to set trap group parameters. Return an error when the 'fail_trap_group_set' debugfs file is set in order to exercise error paths and verify that error is propagated to user space when should.

netdevsim: Add devlink-trap policer support

2020-03-31T00:54:58Z

Register three dummy packet trap policers with devlink and implement callbacks to change their parameters and read their counters. This will be used later on in the series to test the devlink-trap policer infrastructure. v2: * Remove check about burst size being a power of 2 and instead add a debugfs knob to fail the operation * Provide max/min rate/burst size when registering policers and remove the validity checks from nsim_dev_devlink_trap_policer_set() Signed-off-by: Ido Schimmel Reviewed-by: Jiri Pirko Reviewed-by: Jakub Kicinski Signed-off-by: David S.
