so you're just going to truncate the line? no discussion of this in the writeup? can you demonstrate that you're thinking through this?

Yeah truncating it doesn't make sense, I was (wrongfully) referring to the musl implementation. The logic there is not to truncate, but skip entirely if the line is longer than max_len. So from that information, my suggestion would just be adding a line that checks the len before the memcpy:
if(rest.len>max_len)continue;Yeah truncating it doesn't make sense, I was (wrongfully) referring to the musl implementation.
