What happens if the size isn't LOG_BUF_SIZE?

would do you mean?
LOG_BUF_SIZE is just a user defined macro.
Can be anything.

I believe, Andy means, what would happen if log_level > 0 but
the log_size is not big enough so that the human-readable error
text string from the verifier will fit into it? I presume that
will be truncated then ... hm.

it's passed along with pointer:
                        .log_buf = bpf_log_buf,
                        .log_size = LOG_BUF_SIZE,
                        .log_level = 1,
