Chuyi Zhou 3091b66749 bpf: Relax allowlist for css_task iter ... The newly added open-coded css_task iter would try to hold the global css_set_lock in bpf_iter_css_task_new, so the bpf side has to be careful in where it allows to use this iter. The mainly concern is dead locking on css_set_lock. check_css_task_iter_allowlist() in verifier enforced css_task can only be used in bpf_lsm hooks and sleepable bpf_iter. This patch relax the allowlist for css_task iter. Any lsm and any iter (even non-sleepable) and any sleepable are safe since they would not hold the css_set_lock before entering BPF progs context. This patch also fixes the misused BPF_TRACE_ITER in check_css_task_iter_allowlist which compared bpf_prog_type with bpf_attach_type.
