https://git.0xinfinity.dev/distro/kernel.git/atom?h=master2025-09-10T19:34:09Zselftests/bpf: Skip timer cases when bpf_timer is not supported2025-09-10T19:34:09ZLeon Hwang2025-09-10T12:57:40Zurn:sha1:fbdd61c94bcb09b0c0eb0655917bf4193d07aac1
When enable CONFIG_PREEMPT_RT, verifier will reject bpf_timer with
returning -EOPNOTSUPP.
Therefore, skip test cases when errno is EOPNOTSUPP.

selftests/bpf: Add test for bpf_timer overwriting crash2022-02-11T21:13:04ZKumar Kartikeya Dwivedi2022-02-09T07:03:24Zurn:sha1:a7e75016a0753c24d6c995bc02501ae35368e333
Add a test that validates that timer value is not overwritten when doing
a copy_map_value call in the kernel. Without the prior fix, this test
triggers a crash.
