bpf: selftests: Specify CONFIG_DYNAMIC_FTRACE in the testing config

2021-04-03T16:09:50+00:00

The tracing test and the recent kfunc call test require CONFIG_DYNAMIC_FTRACE. This patch adds it to the config file. Signed-off-by: Martin KaFai Lau Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20210403002921.3419721-1-kafai@fb.com

selftests/bpf: Add config dependency on BLK_DEV_LOOP

2020-12-03T19:20:21+00:00

The ima selftest restricts its scope to a test filesystem image mounted on a loop device and prevents permanent ima policy changes for the whole system.

bpf: Add a selftest for bpf_ima_inode_hash

2020-11-25T23:25:47+00:00

The test does the following: - Mounts a loopback filesystem and appends the IMA policy to measure executions only on this file-system. Restricting the IMA policy to a particular filesystem prevents a system-wide IMA policy change. - Executes an executable copied to this loopback filesystem. - Calls the bpf_ima_inode_hash in the bprm_committed_creds hook and checks if the call succeeded and checks if a hash was calculated. The test shells out to the added ima_setup.sh script as the setup is better handled in a shell script and is more complicated to do in the test program or even shelling out individual commands from C. The list of required configs (i.e. IMA, SECURITYFS, IMA_{WRITE,READ}_POLICY) for running this test are also updated.

selftests/bpf: CONFIG_IPV6_SEG6_BPF required for test_seg6_loop.o

test_seg6_loop.o uses the helper bpf_lwt_seg6_adjust_srh(); it will not be present if CONFIG_IPV6_SEG6_BPF is not specified.

selftests/bpf: expand test_tc_tunnel with SIT encap

2019-04-23T23:32:26+00:00

So far, all BPF tc tunnel testcases encapsulate in the same network protocol. Add an encap testcase that requires updating skb->protocol. The 6in4 tunnel encapsulates an IPv6 packet inside an IPv4 tunnel. Verify that bpf_skb_net_grow correctly updates skb->protocol to select the right protocol handler in __netif_receive_skb_core. The BPF program should also manually update the link layer header to encode the right network protocol.

selftests_bpf: extend test_tc_tunnel for UDP encap

2019-04-11T20:50:56+00:00

commit 868d523535c2 ("bpf: add bpf_skb_adjust_room encap flags") introduced support to bpf_skb_adjust_room for GSO-friendly GRE and UDP encapsulation and later introduced associated test_tc_tunnel tests. Here those tests are extended to cover UDP encapsulation also. Signed-off-by: Alan Maguire Signed-off-by: Daniel Borkmann
