Add a ProxyJump ssh_config(5) option and corresponding -J
ssh(1) command-line flag to allow simplified indirection through a SSH
bastion or "jump host".
These options construct a proxy command that connects to the
specified jump host(s) (more than one may be specified) and uses
port-forwarding to establish a connection to the next destination.
This codifies the safest way of indirecting connections through SSH
servers and makes it easy to use.

since these pages now clearly tell folks to avoid v1,
normalise the docs from a v2 perspective (i.e. stop pointing out which bits
are v2 only);

Replace list of ciphers and MACs adjacent to -1/-2 flag

Add an AddKeysToAgent client option which can be set to
'yes', 'no', 'ask', or 'confirm', and defaults to 'no'. When enabled, a
private key that is used during authentication will be added to ssh-agent if
it is running (with confirmation enabled if set to 'confirm').
Initial version from Joachim Schipper many years ago.

UpdateHostKeys fixes:
I accidentally changed the format of the hostkeys@openssh.com messages
last week without changing the extension name, and this has been causing
connection failures for people who are running -current. First reported
by sthen@
s/hostkeys@openssh.com/hostkeys-00@openssh.com/
Change the name of the proof message too, and reorder it a little.
Also, UpdateHostKeys=ask is incompatible with ControlPersist (no TTY
available to read the response) so disable UpdateHostKeys if it is in
ask mode and ControlPersist is active (and document this)
|
|
Revise hostkeys@openssh.com hostkey learning extension.
The client will not ask the server to prove ownership of the private
halves of any hitherto-unseen hostkeys it offers to the client.
Allow UpdateHostKeys option to take an 'ask' argument to let the
user manually review keys offered.

turn UpdateHostkeys off by default until I figure out
mlarkin@'s warning message; requested by deraadt@

Add a ssh_config HostbasedKeyType option to control which
host public key types are tried during hostbased authentication.
This may be used to prevent too many keys being sent to the server,
and blowing past its MaxAuthTries limit.

correct description of UpdateHostKeys in ssh_config.5 and
add it to -o lists for ssh, scp and sftp; pointed out by jmc@
|
|
Host key rotation support.
Add a hostkeys@openssh.com protocol extension (global request) for
a server to inform a client of all its available host key after
authentication has completed. The client may record the keys in
known_hosts, allowing it to upgrade to better host key algorithms
and a server to gracefully rotate its keys.
The client side of this is controlled by a UpdateHostkeys config
option (default on).

Tweak config reparsing with host canonicalisation
Make the second pass through the config files always run when
hostname canonicalisation is enabled.
Add a "Match canonical" criteria that allows ssh_config Match
blocks to trigger only in the second config pass.
Add a -G option to ssh that causes it to parse its configuration
and dump the result to stdout, similar to "sshd -T"
Allow ssh_config Port options set in the second config parse
phase to be applied (they were being ignored).
