selftests/bpf: Fix bpf_iter/task_vma test

2026-07-24T13:54:41+00:00

[ Upstream commit 2e8ad1ff712d2a397e407c9fde60901f68d077dc ] For selftest bpf_iter/task_vma, I got a failure like below on my qemu run: test_task_vma_common:FAIL:compare_output unexpected compare_output: actual '561593546000-561593585000r--p0000000000:241256579534/root/devshare/bpf-next/tools/testing/selftests/bpf/test_progs' != expected '561593546000-561593585000r--p0000000000:245551546830/root/devshare/bpf-next/tools/testing/selftests/bpf/test_progs' Further debugging found out file->f_inode->i_ino value may exceed 32bit, e.g., i_ino = 0x14c2eae35, but the format string is '%u'. This caused inode mismatch between bpf iter and proc result. Fix the issue by using format string '%llu' to accommodate 64bit i_ino.

selftests/bpf: Check for timeout in perf_link test

2026-07-04T11:41:27+00:00

commit e6c209da7e0e9aaf955a7b59e91ed78c2b6c96fb upstream. Recently perf_link test started unreliably failing on libbpf CI: * https://github.com/libbpf/libbpf/actions/runs/11260672407/job/31312405473 * https://github.com/libbpf/libbpf/actions/runs/11260992334/job/31315514626 * https://github.com/libbpf/libbpf/actions/runs/11263162459/job/31320458251 Part of the test is running a dummy loop for a while and then checking for a counter incremented by the test program. Instead of waiting for an arbitrary number of loop iterations once, check for the test counter in a loop and use get_time_ns() helper to enforce a 100ms timeout. v1: https://lore.kernel.org/bpf/zuRd072x9tumn2iN4wDNs5av0nu5nekMNV4PkR-YwCT10eFFTrUtZBRkLWFbrcCe7guvLStGQlhibo8qWojCO7i2-NGajes5GYIyynexD-w=@pm.me/ Signed-off-by: Ihor Solodrai Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20241011153104.249800-1-ihor.solodrai@pm.me Signed-off-by: Shung-Hsi Yu Signed-off-by: Sasha Levin

selftests/bpf: Move get_time_ns to testing_helpers.h

2026-07-04T11:41:27+00:00

commit 3830d04a7401f277185e4439eb259c1b13e76788 upstream. We'd like to have single copy of get_time_ns used b bench and test_progs, but we can't just include bench.h, because of conflicting 'struct env' objects. Moving get_time_ns to testing_helpers.h which is being included by both bench and test_progs objects.

selftests/bpf: move SYS() macro into the test_progs.h

2026-07-04T11:41:27+00:00

commit b61987d37cbee3c44e80304598c60b163553926b upstream. A lot of tests defined SYS() macro to run system calls with goto label. Let's move this macro to test_progs.h and add configurable "goto_label" as the first arg.

selftests/bpf: Fix bpf_nf selftest failure

2026-06-19T11:37:32+00:00

commit 967e8def1100cb4b08c28a54d27ce69563fdf281 upstream. For systems with missing iptables-legacy tool this selftest fails. Add check to find if iptables-legacy tool is available and skip the test if the tool is missing.

selftests/bpf: S/iptables/iptables-legacy/ in the bpf_nf and xdp_synproxy test

2026-06-19T11:36:57+00:00

[ Upstream commit de9c8d848d90cf2e53aced50b350827442ca5a4f ] The recent vm image in CI has reported error in selftests that use the iptables command. Manu Bretelle has pointed out the difference in the recent vm image that the iptables is sym-linked to the iptables-nft. With this knowledge, I can also reproduce the CI error by manually running with the 'iptables-nft'. This patch is to replace the iptables command with iptables-legacy to unblock the CI tests.

selftests/bpf: Fix ARG_PTR_TO_LONG {half-,}uninitialized test

2026-06-19T11:36:57+00:00

[ Upstream commit b8e188f023e07a733b47d5865311ade51878fe40 ] The assumption of 'in privileged mode reads from uninitialized stack locations are permitted' is not quite correct since the verifier was probing for read access rather than write access. Both tests need to be annotated as __success for privileged and unprivileged.

Revert "selftests/bpf: Add a cgroup prog bpf_get_ns_current_pid_tgid() test"

2026-06-19T11:36:57+00:00

This reverts commit 4d8fb7ed7a55 ("selftests/bpf: Add a cgroup prog bpf_get_ns_current_pid_tgid() test"). That commit should have never been backported to 6.1 because it introduces a test for a feature that isn't supported: bpf_get_ns_current_pid_tgid() cannot be called from cgroup BPF programs in 6.1.
