Some notable changes, from upstream's release notes:
- sshd(8): Remove support for obsolete "host/port" syntax.
- ssh(1): When prompting whether to record a new host key, accept the key
fingerprint as a synonym for "yes".
- ssh-keygen(1): when acting as a CA and signing certificates with an RSA
key, default to using the rsa-sha2-512 signature algorithm.
- ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa"
(RSA/SHA1) algorithm from those accepted for certificate signatures.
- ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F
support to provide address-space isolation for token middleware
libraries (including the internal one).
- ssh(1): this release enables UpdateHostkeys by default subject to some
conservative preconditions.
- scp(1): this release changes the behaviour of remote to remote copies
(e.g. "scp host-a:/path host-b:") to transfer through the local host
by default.
- scp(1): experimental support for transfers using the SFTP protocol as
a replacement for the venerable SCP/RCP protocol that it has
traditionally used.
Additional integration work is needed to support FIDO/U2F in the base
system.
Deprecation Notice
------------------
OpenSSH will disable the ssh-rsa signature scheme by default in the
next release.

This code was originally written for non-reentrant crypt(3).
In 5f521d7ba7, a thread-safe crypt_r(3) was introduced. However,
it looks like the DES implementation is still not re-entrant;
routines like setup_salt() or des_setkey() still use global
variables.
Instead of something drastic, eg removing DES support altogether,
just mark those variables as thread-local. This adds about 30kB
of data per thread.
Given that this only applies to DES, I think the impact is minimal.

This merges upstream patches from OpenSSL's master branch to add
KTLS infrastructure for TLS 1.0-1.3 including both RX and TX
offload and SSL_sendfile support on both Linux and FreeBSD.
Note that TLS 1.3 only supports TX offload.
A new WITH/WITHOUT_OPENSSL_KTLS determines if OpenSSL is built with
KTLS support. It defaults to enabled on amd64 and disabled on all
other architectures.

Literal references to /usr/local exist in a large number of files in
the FreeBSD base system. Many are in contributed software, in configuration
files, or in the documentation, but 19 uses have been identified in C
source files or headers outside the contrib and sys/contrib directories.
This commit makes it possible to set _PATH_LOCALBASE in paths.h to use
a different prefix for locally installed software.
In order to avoid changes to openssh source files, LOCALBASE is passed to
the build via Makefiles under src/secure. While _PATH_LOCALBASE could have
been used here, there is precedent in the construction of the path used to
a xauth program which depends on the LOCALBASE value passed on the compiler
command line to select a non-default directory.
This could be changed in a later commit to make the openssh build
consistently use _PATH_LOCALBASE. It is considered out-of-scope for this
commit.

The current default is provided in various Makefile.inc in some top-level
directories and covers a good portion of the tree, but doesn't cover parts
of the build a little deeper (e.g. libcasper).
Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that
variable is defined. This lets us relatively cleanly provide a default WARNS
no matter where you're building in the src tree without breaking things
outside of the tree.
Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to
successfully walk over this change on WITHOUT_CLEAN builds has been added.
There is a supplemental project to this to list all of the warnings that are

The proper procedure was not followed in r364943; all of these that were
deleted should have instead been moved over to the blacklist so that certctl
can DTRT.
Users must still `certctl rehash` after this, but this should generally be
done by one of mergemaster/etcupdate/freebsd-update/pkgbase already; note
that freebsd-update doesn't come into play for this particular update, as
these have not yet made it into a release.
Future work (after svn -> git) will likely change the script that updatecert
invokes to facilitate the process, rather than trusting that kevans or
whomever updates in the future will remember.

This solves an issue on stable/12 that causes certs to not get installed.
ls is apparently not in PATH during installworld, so TRUSTED_CERTS ends up

SSLv3 has been deprecated since 2015 (and broken since 2014: "POODLE"); it
should not have shipped in FreeBSD 11 (2016) or 12 (2018). No one should use
it, and if they must, they can use some implementation outside of base.
There are three symbols removed with OPENSSL_NO_SSL3_METHOD:
SSLv3_client_method
SSLv3_method
SSLv3_server_method
These symbols exist to request an explicit SSLv3 connection to a server.
There is no good reason for an application to link or invoke these symbols
instead of TLS_method(), et al (née SSLv23_method, et al). Applications
that do so have broken cryptography.
Define these symbols for some pedantic definition of ABI stability, but
remove the functionality again (r361392) after r362620.

This define caused a couple of symbols to disappear. To keep ABI
compatibility, we are going to keep the symbols exposed, but leave SSLv3 as
not in the default config (this is what OPENSSL_NO_SSL3 achieves). The
ramifications of this is an application can still use SSLv3 if it
specifically calls the SSLv3_method family of APIs.

The original intention for caroot was to be packaged separately, perhaps so
that users can have a more/less conservative upgrade policy for this
separated from the rest of base.
secure/caroot/Makefile doesn't have anything interesting to package, but its
subdirectories might. Move the PACKAGE= to Makefile.inc so both blacklisted
and trusted get packaged consistently into the correct one rather than the
default -utilities. Also tag the directories for package=caroot, as they
could also be empty; blacklisted is empty by default, but trusted is not.
Add a post-install script to do certctl rehash, along with a note should we
eventually come up with a way to detect that files have been added or
removed that requires a rehash.
-caroot gets a dependency on -utilities, as that's where we provide certctl
at the moment. We can perhaps reconsider this and put certctl into this
package in the future, but there are some bits within -utilities that
unconditionally invoke certctl so let's hold off for now.

This kind of automagica got picked up in trusted/ prior to the initial
commit, but never got applied over in blacklisted. Ideally no one will be
using blacklisted/ to store arbitrary certs that they don't intend to
blacklist, so we should just install anything that's in here rather than
force consumer to first copy cert into place and then modify the file
listing in the Makefile.
Wise man once say: "it is better to restrict too much, than not enough.
sometimes."
This directory stages certdata into .OBJDIR and processes it, but does not
actually build a prog-shaped object; bsd.obj.mk provides the minimal support
that we actually need, an .OBJDIR and descent into subdirs. This is
admittedly the nittiest of nits.

Interested users can blacklist any/all of these with certctl(8), examples:
- mv /usr/share/certs/trusted/... /usr/share/certs/blacklisted/...; \
certctl rehash
- certctl blacklist /usr/share/certs/trusted/*; \
certctl rehash
Certs can be easily examined after installation with `certctl list`, and
certctl blacklist will accept the hashed filename as output by list or as
seen in /etc/ssl/certs

- CAROOT option to opt out of installation of certs
- mtree amendments for final destinations
- infrastructure to fetch/update certs, along with instructions
