selftests/bpf: add test for mixing generic and offload XDP

2019-02-06T14:35:42Z

Add simple sanity check for enabling generic and offload XDP, simply reuse the native and offload checks. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

selftests/bpf: print traceback when test fails

2019-02-06T14:35:42Z

Figuring out which exact check in test_offload.py takes more time than it should. Print the traceback (to the screen and the logs). Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

selftests/bpf: fix the expected messages

2019-02-06T14:35:41Z

Recent changes added extack to program replacement path, expect extack instead of generic messages. Fixes: 01dde20ce04b ("xdp: Provide extack messages when prog attachment failed") Signed-off-by: Jakub Kicinski Signed-off-by: Daniel Borkmann

selftests/bpf: add test for sharing objects between netdevs

2018-07-18T13:10:34Z

Add tests for sharing programs and maps between different netdevs. Use netdevsim's ability to pretend multiple netdevs belong to the same "ASIC". Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: associate bound programs with shared dev

2018-07-18T13:10:33Z

Move bound program information from netdevsim to shared sub-object, as programs will soon be shared between netdevs of the same ASIC. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

selftests/bpf: add test for multiple programs

2018-07-13T18:26:35Z

Add tests for having an XDP program attached in the driver and another one attached in HW simultaneously. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann

netdevsim: add support for simultaneous driver and hw XDP

2018-07-13T18:26:35Z

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

xdp: factor out common program/flags handling from drivers

2018-07-13T18:26:35Z

Basic operations drivers perform during xdp setup and query can be moved to helpers in the core. Encapsulate program and flags into a structure and add helpers. Note that the structure is intended as the "main" program information source in the driver. Most drivers will additionally place the program pointer in their fast path or ring structures. The helpers don't have a huge impact now, but they will decrease the code duplication when programs can be installed in HW and driver at the same time. Encapsulating the basic operations in helpers will hopefully also reduce the number of changes to drivers which adopt them. Helpers could really be static inline, but they depend on definition of struct netdev_bpf which means they'd have to be placed in netdevice.h, an already 4500 line header.

selftests/bpf: add Error: prefix in check_extack helper

2018-07-11T20:13:33Z

Currently the test only checks errors, not warnings, so save typing and prefix the extack messages with "Error:" inside the check helper. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet Signed-off-by: Daniel Borkmann
