The commentary (in which you talked about restoring the patch and squashing) seemed to imply that this had been posted somewhere before, but it wasn't marked as "v2" (or whatever attempt) and lacked a URL pointing at the previous attempt, so it was difficult to judge. > On Thu, Nov 23, 2017 at 08:30:39PM -0500, Eric Sunshine wrote: >>> +static ssize_t read_request_fix_len(int fd, size_t req_len, unsigned char **out) >> >> Wrong data type: s/size_t req_len/ssize_t req_len/ > > Passing negative value to the function makes no sense.
