Apologies - I accidentally pushed this.

Allows the -b and -B options to be used together.
For example, when the interface is in the VRF.

to obtain known_hosts data from a command in addition to the usual files.
The command accepts bunch of %-expansions, including details of the
connection and the offered server host key. Note that the command may
be invoked up to three times per connection (see the manpage for
details).

Add load_hostkeys_file() and hostkeys_foreach_file() that accept a
FILE* argument instead of opening the file directly.
Original load_hostkeys() and hostkeys_foreach() are implemented using
these new interfaces.
Add a u_int note field to the hostkey_entry and hostkey_foreach_line
structs that is passed directly from the load_hostkeys() and
hostkeys_foreach() call. This is a lightweight way to annotate results
between different invocations of load_hostkeys().

TCP connect. The connection phase of the SSH session is time-sensitive (due
to server side login grace periods) and is frequently interactive (e.g.
entering passwords). The ultimate interactive/bulk TOS/DSCP will be set after
authentication completes.

find_by_key_ctx struct. Initializing a single member should be enough
(the spec says the remainder should be initialized as per the static

If host key checking fails (i.e. a wrong host key is recorded for the
server) and the user elects to continue (via StrictHostKeyChecking=no),
then disable UpdateHostkeys for the session.

some arbitrary value < 0. errno is only updated in this case. Change all
(most?) callers of syscalls to follow this better, and let's see if this
strictness helps us in the future.

speculation and memory sidechannel attacks like Spectre, Meltdown, Rowhammer
and Rambleed. This change encrypts private keys when they are not in use with
a symmetic key that is derived from a relatively large "prekey" consisting of
random data (currently 16KB).
Attackers must recover the entire prekey with high accuracy before
they can attempt to decrypt the shielded private key, but the current
generation of attacks have bit error rates that, when applied
cumulatively to the entire prekey, make this unlikely.
Implementation-wise, keys are encrypted "shielded" when loaded and then
automatically and transparently unshielded when used for signatures or
when being saved/serialised.
Hopefully we can remove this in a few years time when computer
architecture has become less unsafe.

API, started almost exactly six years ago.
This change stops including the old packet_* API by default and makes
each file that requires the old API include it explicitly. We will
commit file-by-file refactoring to remove the old API in consistent
steps.

ssh->kex and factor out the banner exchange. This eliminates some common code
from the client and server.
Also be more strict about handling \r characters - these should only
be accepted immediately before \n (pointed out by Jann Horn).
