sshd(8): Disable tunneled cleartext passwords.

This was previously our default that got wiped away when I removed our
local changes to OpenSSH. It's unlikely that anyone running master saw
any change to their sshd behavior, because they likely had the
PasswordAuthentication line uncommented in their configuration file.

Remove most local modifications from OpenSSH.

This primarily removes the HPN patches. It's become too cumbersome to
maintain these patches as demonstrated by the fact that we haven't
updated OpenSSH in quite some time. If people want additional
functionality in their OpenSSH, it's available in dports
(security/openssh).

Instead of just silently ignoring removed options in people's
configurations, I decided to treat these as errors so that the admin
will need to decide to remove it from their configuration or install the
dport to get the functionality back.

The original author made a decent case for removing this in 2013:

Import OpenSSH-6.1p1.

Features:

* ssh-keygen(1): Add optional checkpoints for moduli screening
* ssh-add(1): new -k option to load plain keys (skipping certificates)
* sshd(8): Add wildcard support to PermitOpen, allowing things like
"PermitOpen localhost:*". bz #1857
* ssh(1): support for cancelling local and remote port forwards via the
multiplex socket. Use ssh -O cancel -L xx:xx:xx -R yy:yy:yy user@host"
to request the cancellation of the specified forwardings
* support cancellation of local/dynamic forwardings from ~C commandline
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
* ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
* sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
an argument to refuse all port-forwarding requests.
* sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.

Bugfixes:

* ssh(1): ensure that $DISPLAY contains only valid characters before
using it to extract xauth data so that it can't be used to play local
shell metacharacter games.
* ssh(1): unbreak remote portforwarding with dynamic allocated listen ports
* scp(1): uppress adding '--' to remote commandlines when the first
argument does not start with '-'. saves breakage on some
difficult-to-upgrade embedded/router platforms
* ssh(1)/sshd(8): fix typo in IPQoS parsing: there is no "AF14" class,
but there is an "AF21" class
* ssh(1)/sshd(8): do not permit SSH2_MSG_SERVICE_REQUEST/ACCEPT during
rekeying
* ssh(1): skip attempting to create ~/.ssh when -F is passed
* sshd(8): unbreak stdio forwarding when ControlPersist is in use; bz#1943
* sshd(1): send tty break to pty master instead of (probably already
closed) slave side; bz#1859
* sftp(1): silence error spam for "ls */foo" in directory with files;
bz#1683
* Fixed a number of memory and file descriptor leaks
* ssh(1)/sshd(8): Don't spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025
* ssh(1): Delay setting tty_flag so RequestTTY options are correctly
picked up. bz#1995
* sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
on platforms that use login_cap.

Import OpenSSH-5.9p1.

* Introduce sandboxing of the pre-auth privsep child using an optional
sshd_config(5) "UsePrivilegeSeparation=sandbox" mode that enables
mandatory restrictions on the syscalls the privsep child can perform.
This intention is to prevent a compromised privsep child from being
used to attack other hosts (by opening sockets and proxying) or
probing local kernel attack surface.

The rlimit sandbox is a fallback choice for platforms that don't
support a better one; it uses setrlimit() to reset the hard-limit
of file descriptors and processes to zero, which should prevent
the privsep child from forking or opening new network connections.

* Add new SHA256-based HMAC transport integrity modes from
http://www.ietf.org/id/draft-dbider-sha2-mac-for-ssh-02.txt
These modes are hmac-sha2-256, hmac-sha2-256-96, hmac-sha2-512,
and hmac-sha2-512-96, and are available by default in ssh(1) and
sshd(8)

* The pre-authentication sshd(8) privilege separation slave process
now logs via a socket shared with the master process, avoiding the
need to maintain /dev/log inside the chroot.

* ssh(1) now warns when a server refuses X11 forwarding

* sshd_config(5)'s AuthorizedKeysFile now accepts multiple paths,
separated by whitespace. The undocumented AuthorizedKeysFile2
option is deprecated (though the default for AuthorizedKeysFile
includes .ssh/authorized_keys2)

* sshd_config(5): similarly deprecate UserKnownHostsFile2 and
GlobalKnownHostsFile2 by making UserKnownHostsFile and
GlobalKnownHostsFile accept multiple options and default to
include known_hosts2

* Retain key comments when loading v.2 keys. These will be visible
in "ssh-add -l" and other places. bz#439

* ssh(1) and sshd(8): set IPv6 traffic class from IPQoS (as well as
IPv4 ToS/DSCP). bz#1855

* ssh_config(5)'s ControlPath option now expands %L to the host
portion of the destination host name.

* ssh_config(5) "Host" options now support negated Host matching, e.g.

Host *.example.org !c.example.org
User mekmitasdigoat

Will match "a.example.org", "b.example.org", but not "c.example.org"

* ssh_config(5): a new RequestTTY option provides control over when a
TTY is requested for a connection, similar to the existing -t/-tt/-T
ssh(1) commandline options.

* sshd(8): allow GSSAPI authentication to detect when a server-side
failure causes authentication failure and don't count such failures
against MaxAuthTries; bz#1244

* ssh-keygen(1): Add -A option. For each of the key types (rsa1, rsa,
dsa and ecdsa) for which host keys do not exist, generate the host
keys with the default key file path, an empty passphrase, default
bits for the key type, and default comment. This is useful for
system initialization scripts.

* ssh(1): Allow graceful shutdown of multiplexing: request that a mux
server removes its listener socket and refuse future multiplexing
requests but don't kill existing connections. This may be requested
using "ssh -O stop ..."

* ssh-add(1) now accepts keys piped from standard input. E.g.
"ssh-add - < /path/to/key"

* ssh-keysign(8) now signs hostbased authentication
challenges correctly using ECDSA keys; bz#1858

* sftp(1): document that sftp accepts square brackets to delimit
addresses (useful for IPv6); bz#1847a

* ssh(1): when using session multiplexing, the master process will
change its process title to reflect the control path in use and
when a ControlPersist-ed master is waiting to close; bz#1883 and
bz#1911

* Other minor bugs fixed: 1849 1861 1862 1869 1875 1878 1879 1892
1900 1905 1913

Import OpenSSH-5.8p1.

* Fix vulnerability in legacy certificate signing introduced in
OpenSSH-5.6.

* Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA
offer better performance than plain DH and DSA at the same equivalent
symmetric key length, as well as much shorter keys.

* sftp(1)/sftp-server(8): add a protocol extension to support a hard
link operation. It is available through the "ln" command in the
client. The old "ln" behaviour of creating a symlink is available
using its "-s" option or through the preexisting "symlink" command

* scp(1): Add a new -3 option to scp: Copies between two remote hosts
are transferred through the local host. Without this option the
data is copied directly between the two remote hosts.

* ssh(1): automatically order the hostkeys requested by the client
based on which hostkeys are already recorded in known_hosts. This
avoids hostkey warnings when connecting to servers with new ECDSA
keys, since these are now preferred when learning hostkeys for the
first time.

* ssh(1)/sshd(8): add a new IPQoS option to specify arbitrary
TOS/DSCP/QoS values instead of hardcoding lowdelay/throughput.

* ssh(1): "atomically" create the listening mux socket by binding it on
a temporary name and then linking it into position after listen() has
succeeded. This allows the mux clients to determine that the server
socket is either ready or stale without races. stale server sockets
are now automatically removed.

* ssh(1)/sshd(8): add a KexAlgorithms knob to the client and server
configuration to allow selection of which key exchange methods are
used by ssh(1) and sshd(8) and their order of preference.

* sftp(1)/scp(1): factor out bandwidth limiting code from scp(1) into
a generic bandwidth limiter that can be attached using the atomicio
callback mechanism and use it to add a bandwidth limit option to
sftp(1).

BugFixes:

* ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
temporary directories.

* ssh(1): avoid NULL deref on receiving a channel request on an unknown
or invalid channel;

* sshd(8): remove a debug() that pollutes stderr on client connecting
to a server in debug mode

* scp(1): pass through ssh command-line flags and options when doing
remote-remote transfers, e.g. to enable agent forwarding which is
particularly useful in this case;

* sftp-server(8): umask should be parsed as octal

* sftp(1): escape '[' in filename tab-completion

* ssh(1): Typo in confirmation message.

* sshd(8): prevent free() of string in .rodata when overriding
AuthorizedKeys in a Match block

* sshd(8): Use default shell /bin/sh if $SHELL is ""

* ssh(1): kill proxy command on fatal() (we already killed it on
clean exit);

* ssh(1): install a SIGCHLD handler to reap expiried child process;

* sshd(8): Use correct uid_t/pid_t types instead of int.

SSHD - Change default security

This only effects fresh installs.

* Allow root logins via public key only (previously: root logins not allowed
at all via ssh). I've done this for years, it allows an authorized_keys
file in ~root/.ssh to work without having to adjust /etc/ssh/sshd_config
on every install.

* Do not allow any login, root or otherwise, via tunneled plaintext password
(previously: non-root logins were allowed via plaintext password).

Often people want plaintext passwords on e.g. workstations for xdm or
console logins, but do not want to allow their use over networked
connections. Since tunneled plaintext passwords are not considered very
secure and alternatives exist (aka public key logins) we now disallow
them by default.
