2019-08-05selftests/bpf: add wrapper scripts for test_xdp_vlan.shJesper Dangaard Brouer
In-order to test both native-XDP (xdpdrv) and generic-XDP (xdpgeneric) create two wrapper test scripts, that start the test_xdp_vlan.sh script with these modes. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-08-05bpf: fix XDP vlan selftests test_xdp_vlan.shJesper Dangaard Brouer
Change BPF selftest test_xdp_vlan.sh to (default) use generic XDP. This selftest was created together with a fix for generic XDP, in commit 297249569932 ("net: fix generic XDP to handle if eth header was mangled"). And was suppose to catch if generic XDP was broken again. The tests are using veth and assumed that veth driver didn't support native driver XDP, thus it used the (ip link set) 'xdp' attach that fell back to generic-XDP. But veth gained native-XDP support in 948d4f214fde ("veth: Add driver XDP"), which caused this test script to use native-XDP. Fixes: 948d4f214fde ("veth: Add driver XDP") Fixes: 97396ff0bc2d ("selftests/bpf: add XDP selftests for modifying and popping VLAN headers") Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.

2019-08-03cgroup: kselftest: relax fs_spec checksChris Down
On my laptop most memcg kselftests were being skipped because it claimed cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it seems current systemd HEAD mounts it with the name "cgroup2" instead of "cgroup": % grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0 I can't think of a reason to need to check fs_spec explicitly since it's arbitrary, so we can just rely on fs_vfstype. After these changes, `make TARGETS=cgroup kselftest` actually runs the cgroup v2 tests in more cases.

The livepatching self-tests tweak the dynamic debug config to verify the kernel log during the tests. Enhance set_dynamic_debug() so that the config changes are restored when the script exits.

Previously, using "%m" in a ksft_* format string can result in strange output because the errno value wasn't saved before calling other libc functions. The solution is to simply save and restore the errno before we format the user-supplied format string.

2019-07-29libperf: Adopt simplified perf_evsel__open() function from tools/perfJiri Olsa
Add a perf_evsel__open() function to libperf. It's a simplified version of evsel__open() without the fallback mechanism. We can try to merge it in the future to libperf, but it has many details, lets start simple, requiring the latest kernel, perf should continue using its evsel__open() version, continuing to support running on older kernels when possible.
