man pages with pseudo synopses which list filenames end up creating very ugly output in man -k; after some discussion with ingo, we feel the simplest fix is to remove such SYNOPSIS sections: the info is hardly helpful at page top, is contained already in FILES, and there are sufficiently few that just zapping them is simple; ok schwarze, who also helpfully ran things through a build to check output; Upstream-ID: 3e211b99457e2f4c925c5927d608e6f97431336c

2016-09-12upstream commitdjm@openbsd.org
remove 3des-cbc from the client's default proposal; 64-bit block ciphers are not safe in 2016 and we don't want to wait until attacks like sweet32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the defaults, but it's highly likely that such devices already need explicit configuration for KEX and hostkeys anyway. ok deraadt, markus, dtucker Upstream-ID: a505dfe65c6733af0f751b64cbc4bb7e0761bc2f

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. ok markus@ Upstream-ID: fa899cb8b26d889da8f142eb9774c1ea36b04397

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)
