Currently, CodeQL mis-identifies a couple instances of the
usually-legitimate "User-controlled data may not be null terminated"
problem.
In these instances, CodeQL thinks that `packet_txt_read()` fails to
NUL-terminate (not actually "null"... tsk, tsk) the string. But it
totally does! Here is the current definition of that function:
size_t packet_txt_read(char *buf, size_t count, FILE *stream)
{
size_t len;
len = packet_bin_read(buf, count, stream);
if (len && buf[len - 1] == '\n')
{
len--;
}
buf[len] = 0;
return len;
}
The `buf[len] = 0` statement guarantees that the string is
NUL-terminated.
