#     crypto: chacha20poly1305 - prevent integer overflow on large input
#     
#     This code assigns src_len (size_t) to sl (int), which causes problems
#     when src_len is very large. Probably nobody in the kernel should be
#     passing this much data to chacha20poly1305 all in one go anyway, so I
#     don't think we need to change the algorithm or introduce larger types
#     or anything. But we should at least error out early in this case and
#     print a warning so that we get reports if this does happen and can look
#     into why anybody is possibly passing it that much data or if they're
#     accidently passing -1 or similar.
#     
#     Fixes: d95312a3ccc0 ("crypto: lib/chacha20poly1305 - reimplement crypt_from_sg() routine")
