2021-08-23bpf: Migrate cgroup_bpf to internal cgroup_bpf_attach_type enumDave Marchevsky1-1/+1
Add an enum (cgroup_bpf_attach_type) containing only valid cgroup_bpf attach types and a function to map bpf_attach_type values to the new enum. Inspired by netns_bpf_attach_type. Then, migrate cgroup_bpf to use cgroup_bpf_attach_type wherever possible. Functionality is unchanged as attach_type_to_prog_type switches in bpf/syscall.c were preventing non-cgroup programs from making use of the invalid cgroup_bpf array slots. As a result struct cgroup_bpf uses 504 fewer bytes relative to when its arrays were sized using MAX_BPF_ATTACH_TYPE. bpf_cgroup_storage is notably not migrated as struct bpf_cgroup_storage_key is part of uapi and contains a bpf_attach_type member which is not meant to be opaque. Similarly, bpf_cgroup_link continues to report its bpf_attach_type member to userspace via fdinfo and bpf_link_info. To ease disambiguation, bpf_attach_type variables are renamed from 'type' to 'atype' when changed to cgroup_bpf_attach_type.

2021-08-17selftests/bpf: Fix flaky send_signal testYonghong Song1-0/+16
libbpf CI has reported send_signal test is flaky although I am not able to reproduce it in my local environment. But I am able to reproduce with on-demand libbpf CI ([1]). Through code analysis, the following is possible reason. The failed subtest runs bpf program in softirq environment. Since bpf_send_signal() only sends to a fork of "test_progs" process. If the underlying current task is not "test_progs", bpf_send_signal() will not be triggered and the subtest will fail. To reduce the chances where the underlying process is not the intended one, this patch boosted scheduling priority to -20 (highest allowed by setpriority() call). And I did 10 runs with on-demand libbpf CI with this patch and I didn't observe any failures.

2021-08-17selftests: net: improved IOAM testsJustin Iurman2-401/+1074
As previously discussed with David Ahern, here is a refactored and improved version of the IOAM self-test. It is now more complete and more robust. Now, all tests are divided into three categories: OUTPUT (evaluates the IOAM processing by the sender), INPUT (evaluates the IOAM processing by the receiver) and GLOBAL (evaluates wider use cases that do not fall into the other two categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL tests use the entire three-node topology (alpha, beta, gamma). Each test is documented inside its own handler in the (bash) script. Signed-off-by: Justin Iurman <[email protected]> Signed-off-by: David S. Miller <[email protected]>
