tools/bpf: add a bpf selftest for stacktrace

2018-01-06T22:52:23Z

Added a bpf selftest in test_progs at tools directory for stacktrace. The test will populate a hashtable map and a stacktrace map at the same time with the same key, stackid. The user space will compare both maps, using BPF_MAP_LOOKUP_ELEM command and BPF_MAP_GET_NEXT_KEY command, to ensure that both have the same set of keys.

Lots of overlapping changes. Also on the net-next side the XDP state management is handled more in the generic layers so undo the 'net' nfp fix which isn't applicable in net-next. Include a necessary change by Jakub Kicinski, with log message: ==================== cls_bpf no longer takes care of offload tracking. Make sure netdevsim performs necessary checks. This fixes a warning caused by TC trying to remove a filter it has not added. Signed-off-by: Jakub Kicinski Reviewed-by: Quentin Monnet ==================== Signed-off-by: David S. Miller

bpf: Fix tools and testing build.

2017-12-19T23:15:05Z

I'm getting various build failures on sparc64. The key is usually that the userland tools get built 32-bit. 1) clock_gettime() is in librt, so that must be added to the link libraries. 2) "sizeof(x)" must be printed with "%Z" printf prefix.

selftests/bpf: add xdp noinline test

2017-12-17T19:34:36Z

add large semi-artificial XDP test with 18 functions to stress test bpf call verification logic Signed-off-by: Alexei Starovoitov Acked-by: Daniel Borkmann Signed-off-by: Daniel Borkmann

selftests/bpf: add bpf_call test

strip always_inline from test_l4lb.c and compile it with -fno-inline to let verifier go through 11 function with various function arguments and return values Signed-off-by: Alexei Starovoitov Acked-by: Daniel Borkmann Signed-off-by: Daniel Borkmann

bpf/tracing: add a bpf test for new ioctl query interface

2017-12-12T16:46:40Z

Added a subtest in test_progs. The tracepoint is sched/sched_switch. Multiple bpf programs are attached to this tracepoint and the query interface is exercised. Signed-off-by: Yonghong Song Acked-by: Alexei Starovoitov Acked-by: Peter Zijlstra (Intel) Signed-off-by: Alexei Starovoitov

bpf: Test new fields in bpf_attr and bpf_{prog, map}_info

2017-09-29T05:17:05Z

This patch tests newly added fields of the bpf_attr, bpf_prog_info and bpf_map_info. Signed-off-by: Martin KaFai Lau Acked-by: Alexei Starovoitov Acked-by: Daniel Borkmann Signed-off-by: David S. Miller

bpf: Swap the order of checking prog_info and map_info

2017-09-29T05:17:05Z

This patch swaps the checking order. It now checks the map_info first and then prog_info. It is a prep work for adding test to the newly added fields (the map_ids of prog_info field in particular).

selftests/bpf: check the instruction dumps are populated

2017-08-28T22:35:18Z

Add a basic test for checking whether kernel is populating the jited and xlated BPF images. It was used to confirm the behaviour change from commit d777b2ddbecf ("bpf: don't zero out the info struct in bpf_obj_get_info_by_fd()"), which made bpf_obj_get_info_by_fd() usable for retrieving the image dumps.

bpf: selftests add sockmap tests

2017-08-16T18:27:53Z

This generates a set of sockets, attaches BPF programs, and sends some simple traffic using basic send/recv pattern. Additionally, we do a bunch of negative tests to ensure adding/removing socks out of the sockmap fail correctly. Signed-off-by: John Fastabend Signed-off-by: David S. Miller
