in the struct utmp due to concerns about the length of the hostname buffer.
However, this breaks the UseDNS option. There is a simpler and better
solution: initialize utmp_len to the correct value (UT_HOSTSIZE instead of
MAXHOSTNAMELEN) and let get_remote_name_or_ip() worry about the size of the
buffer.

I have worked hard to reduce diffs against the vendor branch. One
notable change in that respect is that we no longer prefer DSA over
RSA - the reasons for doing so went away years ago. This may cause
some surprises, as ssh will warn about unknown host keys even for
hosts whose keys haven't changed.

with OpenSSL 0.9.8 import.
Note that this does not enable cryptodev by default, as it was the
case with OpenSSL 0.9.7 in FreeBSD base, but this change makes it
possible to enable cryptodev at all.

From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.
Security: CVE-2007-4995

casts a bit less evil.
This was e.g. seen when using portsnap as:
Fetching snapshot tag from portsnap3.FreeBSD.org... Illegal instruction
Note the patch is slightly different from kan's original patch to
match style in the OpenSSL source files a bit better.

EVP_CIPHER_CTX_key_length() should return the set key length
in the EVP_CIPHER_CTX structure which may not be the same as
the underlying cipher key length for variable length ciphers.
This fixes problems in OpenSSH using some ciphers, and possibly other
applications.
