Alexei Starovoitov 86f44fcec2 bpf: Disallow bpf programs call prog_run command. ... The verifier cannot perform sufficient validation of bpf_attr->test.ctx_in pointer, therefore bpf programs should not be allowed to call BPF_PROG_RUN command from within the program. To fix this issue split bpf_sys_bpf() bpf helper into normal kern_sys_bpf() kernel function that can only be used by the kernel light skeleton directly. Reported-by: YiFei Zhu <zhuyifei@google.com> Fixes: b1d18a7574 ("bpf: Extend sys_bpf commands for bpf_syscall programs.")
