Add compatibility aliases for ProtocolKeepAlives and SetupTimeOut, supported
in previous versions of Debian's OpenSSH package but since superseded by
ServerAliveInterval. (We're probably stuck with this bit for
compatibility.)
In batch mode, default ServerAliveInterval to five minutes.
Adjust documentation to match and to give some more advice on use of
keepalives.

This patch has been rejected upstream: "None of the OpenSSH developers are
in favour of adding this, and this situation has not changed for several
years. This is not a slight on Simon's patch, which is of fine quality, but
just that a) we don't trust GSSAPI implementations that much and b) we don't
like adding new KEX since they are pre-auth attack surface. This one is
particularly scary, since it requires hooks out to typically root-owned
system resources."
However, quite a lot of people rely on this in Debian, and it's better to
have it merged into the main openssh package rather than having separate
-krb5 packages (as we used to have). It seems to have a generally good
security history.

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.

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

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).
