  "message": "bpf: Add bpf_verifier_vlog() and bpf_verifier_log_needed()\n\nThe BTF (BPF Type Format) verifier needs to reuse the current\nBPF verifier log.  Hence, it requires the following changes:\n\n(1) Expose log_write() in verifier.c for other users.\n    Its name is renamed to bpf_verifier_vlog().\n\n(2) The BTF verifier also needs to check\n\u0027log-\u003elevel \u0026\u0026 log-\u003eubuf \u0026\u0026 !bpf_verifier_log_full(log);\u0027\nindependently outside of the current log_write().  It is\nbecause the BTF verifier will do one-check before\nmaking multiple calls to btf_verifier_vlog to log\nthe details of a type.\n\nHence, this check is also re-factored to a new function\nbpf_verifier_log_needed().  Since it is re-factored,\nwe can check it before va_start() in the current\nbpf_verifier_log_write() and verbose().\n\nSigned-off-by: Martin KaFai Lau \u003ckafai@fb.com\u003e\nAcked-by: Alexei Starovoitov \u003cast@fb.com\u003e\nSigned-off-by: Daniel Borkmann \u003cdaniel@iogearbox.net\u003e\n",
