The java.net.ProxySelector is quite a bit different from the one
in Eclipse. Eclipse (and the OS) uses "socks" as URI scheme to
look up a SOCKS proxy. java.net.ProxySelector needs "socket" as
scheme (and internally maps that to "socks" if and when it asks
the OS about the proxies).
Moreover, java.net.ProxySelector may return unresolved addresses,
whereas the Eclipse proxy selector always returns resolved addresses.
Fix both by explicitly resolving unresolved proxy addresses and using
scheme "socket" in the DefaultProxyDataFactory.
Tested manually with the jgit command-line tool using ssh -vvv -D7020
localhost and 3proxy as SOCKS5 proxies on localhost (3proxy with
user/password authentication). Start jgit with _JAVA_OPTIONS set to
"-DsocksProxyHost=<host> -DsocksProxyPort=<port>
-Djava.net.useSystemProxies=false" to test manually.

The same effect could already be obtained if the ~/.ssh/config file
did not exist. But that is more difficult to control by clients,
since JGit would pick up the config if it was then created. Therefore
allow specifying a null config explicitly to permanently switch off
config file handling.

RFC 4253 section 4.2 allows an ssh server to send additional lines
before its server identification string. Apache MINA sshd enforces
for these lines the constraints specified for the server identification
line, too: no NUL characters and not longer than 255 characters. That
is too strict. RFC 4253 doesn't mandate this, and it also doesn't
make sense given the rationale for these lines in RFC 4253: a TCP
wrapper may not be aware of SSH restrictions, and may not adhere to
these constraints.
Be more lenient when parsing the server's protocol version. Allow
NULs and longer lines in the preamble, and also handle line endings
more leniently. Only enforce the restrictions for the actual server
identification line.

Add encrypted ed25519 keys in the tests; sshd 2.2.0 can finally
decrypt encrypted new-style OpenSSH key files. (Needs the "unlimited
strength" JCE, which is the default since Java 8u161. On older JREs,
users should install the policy files available from Oracle.)
The "expensive" key added has been generated with OpenSSH's
ssh-keygen -t ed25519 -a 256, i.e., with 256 bcrypt KDF rounds
instead of the default 16. On my machine it takes about 2sec to
decrypt.

The message delaying for the initial SSH messages (client
identification followed by the initial key exchange request)
was broken. sendKexInit() is _also_ called when a new key exchange
is requested. We inadvertently also re-sent the client identification
at that point, which is wrong and makes the server terminate the
connection.
Re-keying occurs from time to time during an SSH connection depending
on time, the number of messages (packets/blocks) exchanged, or the
amount of data exchanged. The net result was that for large
repositories data-intensive operations failed on the first re-keying.
Change the initial message delay such that the two messages for the
client identification and the initial key exchange can be buffered
individually while the proxy protocol is still in progress. The
AbstractClientProxyConnector can now buffer several commands, which
should also resolve bug 544715.

Add tests for password and keyboard-interactive authentication.
Implement password authentication; the default provided by sshd
is non-interactive, which is not useful for JGit.
Make sure the CredentialsProvider gets reset on successive password
retrieval attempts. Otherwise it might always return the same non-
accepted password from a secure storage. (That one was discovered
by actually trying this via EGit; the JGit tests don't catch this.)
Change the default order of authentication mechanisms to prefer
password over keyboard-interactive. This is a mitigation for upstream
bug SSHD-866.[1]
Also include a fix for upstream bug SSHD-867.[2]

This is not about the ssh config ProxyCommand but about programmatic
support for HTTP and SOCKS5 proxies. Eclipse allows the user to
specify such proxies, and JSch at least contains code to connect
through proxies. So our Apache MINA sshd client also should be able
to do this.
Add interfaces and provide two implementations for HTTP and SOCKS5
proxies. Adapt the core code to be able to deal with proxy connections
at all. The built-in client-side support for this in sshd 2.0.0 is
woefully inadequate.
Tested manually by running proxies and then fetching various real-
world repositories via these proxies from different servers. Proxies
tested: ssh -D (SOCKS, anonymous), tinyproxy (HTTP, anonymous), and
3proxy (SOCKS & HTTP, username-password authentication). The GSS-API
authentication is untested since I have no Kerberos setup.

We will get an API evolution problem if we expose as API classes and
interfaces that derive from upstream classes or interfaces. Upstream
interfaces also evolve quite erratically and evolution doesn't seem
to follow semantic versioning.
Introduce a new KeyPasswordProvider interface so that we don't have
to depend on the upstream FilePasswordProvider in our API. (We do
need _some_ abstraction for getting passwords for encrypted keys in
the API; EGit will need to provide its own implementation.)
Move some other upstream dependencies (HostConfigEntry, and various
previously protected methods in SshdSessionFactory) out of the API:
classes moved to internal space, and methods made private.
The only dependencies on upstream interfaces are thus in a few method
parameter types. Those cannot be avoided, but should also not pose
problems.

By default sshd will use its default built-in list, which matches
the one of openssh (as far as the algorithms exist in sshd at all).
But it doesn't handle HostKeyAlgorithms from the ssh config at all.
Implement this as in openssh, including the '+' and '-' modifiers
and reordering the default if there are known host keys for a
server already.

Also use a more robust reader for the known hosts file. The default

Set the internal property on the session as defined in the ssh config.
Note that NumberOfPasswordPrompts in openssh applies independently to
both user logins in keyboard-interactive authentication _and_ to
passphrases for identity files (encrypted keys). Apache MINA sshd uses
the setting only for keyboard-interactive authentication, but not for
identity file passphrase prompts. For identity files, it asks exactly
once. This has been reported as issue SSHD-850 upstream.[1]

needlessly re-trying mechanisms that aren't even configured on the

Since we have no real Kerberos5 test setup, this cannot be fully

that it is skipped when not successful _is_ tested.

Tests that it works with unknown authentications in the list, and
fails if there are no common authentications between server and
client. The latter also tests that the ssh config setting is taken
into account at all.
And promptly the JGit sshd client didn't. Add a fix for this. It's
a tiny bit hacky: Apache MINA looks up a custom property set on a
hierarchy of "PropertyResolver"s starting with the session. On the
session itself this property can never be set since it's read
already in the session constructor before anyone had any chance
to set it. The next element in the resolver hierarchy is the sshd
SshClient, and so we set that property there. Since we use one
SshClient and one ClientSession per JGit SshdSession, this is OK.

Add a new ssh client implementation based on Apach MINA sshd 2.0.0.
This implementation uses JGit's own config file parser and host entry
resolver. Code inspection of the Apache MINA implementation revealed
a few bugs or idiosyncrasies that immediately would re-introduce bugs
already fixed in the past in JGit.
Apache MINA sshd is not without quirks either, and I had to configure
and override more than I had expected. But at least it was all doable
in clean ways.
Apache MINA boasts support for Bouncy Castle, so in theory this should
open the way to using more ssh key algorithms, such as ed25519.
The implementation is in a separate bundle and is still not used in
the core org.eclipse.jgit bundle. The tests re-use the ssh tests from
the core test bundle.
