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. ok markus@ Upstream-ID: a680db2248e8064ec55f8be72d539458c987d5f4

correctly match ECDSA subtype (== curve) for offered/recevied host keys. Fixes connection-killing host key mismatches when a server offers multiple ECDSA keys with different curve type (an extremely unlikely configuration). ok markus, "looks mechanical" deraadt@
2015-01-27upstream commitdjm@openbsd.org
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). ok markus@

[readconf.c readconf.h roaming_client.c ssh.1 ssh.c ssh_config.5] [sshconnect.c sshconnect.h] Implement client-side hostname canonicalisation to allow an explicit search path of domain suffixes to use to convert unqualified host names to fully-qualified ones for host key matching. This is particularly useful for host certificates, which would otherwise need to list unqualified names alongside fully-qualified ones (and this causes a number of problems). "looks fine" markus@
