Expose devices allocated for tun/tap forwarding.
At the client, the device may be obtained from a new %T expansion
for LocalCommand.
At the server, the allocated devices will be listed in a
SSH_TUNNEL variable exposed to the environment of any user sessions
started after the tunnel forwarding was established.

Add URI support to ssh, sftp and scp. For example
ssh://user@host or sftp://user@host/path. The connection parameters
described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since
the ssh fingerprint format in the draft uses md5 with no way to specify the
hash function type. OK djm@

Add 'reverse' dynamic forwarding which combines dynamic
forwarding (-D) with remote forwarding (-R) where the remote-forwarded port
expects SOCKS-requests.
The SSH server code is unchanged and the parsing happens at the SSH
clients side. Thus the full SOCKS-request is sent over the forwarded
channel and the client parses c->output. Parsing happens in
channel_before_prepare_select(), _before_ the select bitmask is
computed in the pre[] handlers, but after network input processing
in the post[] handlers.

Expand ssh_config's StrictModes option with two new
settings:
StrictModes=accept-new will automatically accept hitherto-unseen keys
but will refuse connections for changed or invalid hostkeys.
StrictModes=off is the same as StrictModes=no
Motivation:
StrictModes=no combines two behaviours for host key processing:
automatically learning new hostkeys and continuing to connect to hosts
with invalid/changed hostkeys. The latter behaviour is quite dangerous
since it removes most of the protections the SSH protocol is supposed to
provide.
Quite a few users want to automatically learn hostkeys however, so
this makes that feature available with less danger.
At some point in the future, StrictModes=no will change to be a synonym
for accept-new, with its current behaviour remaining available via
StrictModes=off.

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;

mention curve25519-sha256 KEX
Upstream-ID: 33ae1f433ce4795ffa6203761fbdf86e0d7ffbaf
|
|
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.

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.
