Since from user space side, a tail call is > invoked as a pseudo helper function via bpf_tail_call_proto, the verifier > checks the arguments just like with any other helper function and makes > sure that the first argument (regs[BPF_REG_1])'s type is ARG_PTR_TO_CTX. > > Signed-off-by: Daniel Borkmann <dan...@iogearbox.net> Applied, thanks Daniel. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
