Hello. I have noticed that openbsd-compat/memmem.c from OpenSSH portable is still using an old version of OpenBSD's memmem(). Recently OpenBSD's received a big update to increase performance. It would make sense for OpenSSH to update its version as well. Link: https://cvsweb.openbsd.org/src/lib/libc/string/memmem.c?rev=1.5
