* upstream: sftp: Be a bit more clever about completions
There are commands (e.g. "get" or "put") that accept two
arguments, a local path and a remote path. However, the way
current completion is written doesn't take this distinction into
account and always completes remote or local paths.
By expanding CMD struct and "cmds" array this distinction can be
reflected and with small adjustment to completer code the correct
path can be completed.

* Add dfly62 test target.
* If we haven't found it yet, recheck for sys/stat.h.
On some very old platforms, sys/stat.h needs sys/types.h, however
autoconf 2.71's AC_CHECK_INCLUDES_DEFAULT checks for them in the
opposite order, which in combination with modern autoconf's
"present but cannot be compiled" behaviour causes it to not be
detected.
* Add fallback for old platforms w/out MAP_ANON.
* Remove explicit "default" test config argument.
Not specifying the test config implicitly selects default args.
* Remove unused self-hosted test targets.
* Rename "os" in matrix to "target".
This is in preparation to distinguish this from the host that the runner
runs on in case where they are separate (eg VMs).
* Add "libvirt" label to dfly30.
* Make "config" in matrix singular and pass in env.
This will allow the startup scripts to adapt their behaviour based on
the type and config.
* Run vmstartup from temp dir.
This will allow us to create ephemeral disk images per-runner.
* Rework how selfhosted tests interact with runners.
Previously there was one runner per test target (mostly VMs). This had
a few limitations:
- multiple tests that ran on the same target (eg multiple build
configs) were serialized on availability or that runner.
- it needed manual balancing of VMs over host machines.
To address this, make VMs that use ephemeral disks (ie most of them)
all use a pool of runners with the "libvirt" label. This requires that
we distinguish between "host" and "target" for those. Native runners
and VMs with persistent disks (eg the constantly-updated snapshot ones)
specify the same host and target.
This should improve test throughput.
* Skip unit tests on slow riscv64 hardware.
* Use -fzero-call-used-regs=used on clang 15.
clang 15 seems to have a problem with -fzero-call-used-reg=all which
causes spurious "incorrect signature" failures with ED25519. On those
versions, use -fzero-call-used-regs=used instead. (We may add exceptions
later if specific versions prove to be OK). Also move the GCC version
check to match.

getopt(3) returns '?' when it encounters a flag not present in the in

handle this case with the "default" failure case with no loss of
legibility. Hence, remove all the redundant "case '?':" lines.

control over some SFTP protocol knobs: the copy buffer length and

* upstream: Add channel_force_close()
This will forcibly close an open channel by simulating read/write errors,
draining the IO buffers and calling the detach function.
Previously the detach function was only ever called during channel garbage
collection, but there was no way to signal the user of a channel (e.g.
session.c) that its channel was being closed deliberately (vs. by the
usual state-machine logic). So this adds an extra "force" argument to the
channel cleanup callback to indicate this condition.

* upstream: Implement channel inactivity timeouts
This adds a sshd_config ChannelTimeouts directive that allows channels that
have not seen traffic in a configurable interval to be automatically closed.
Different timeouts may be applied to session, X11, agent and TCP forwarding
channels.
Note: this only affects channels over an opened SSH connection and not
the connection itself. Most clients close the connection when their channels
go away, with a notable exception being ssh(1) in multiplexing mode.

* Use autoconf to find openssl binary.
It's possible to install an OpenSSL in a path not in the system's

specify an rpath) but the openssl binary there may not work. If one is
available on the system path just use that.
* Use our own netcat for dynamic-forward test.
That way we can be surer about its behaviour rather than trying to

OpenSSH is a complete implementation of the SSH protocol (version 2) for secure remote login, command execution and file transfer. It includes a client ssh and server sshd, file transfer utilities scp and sftp as well as tools for key generation (ssh-keygen), run-time key storage (ssh-agent) and a number of supporting programs.
This is a port of OpenBSD's OpenSSH to most Unix-like operating systems, including Linux, OS X and Cygwin. Portable OpenSSH polyfills OpenBSD APIs that are not available elsewhere, adds sshd sandboxing for more operating systems and includes support for OS-native authentication and auditing (e.g. using PAM).
Documentation
The official documentation for OpenSSH are the man pages for each tool:
Stable release tarballs are available from a number of download mirrors. We recommend the use of a stable release for most users. Please read the release notes for details of recent changes and potential incompatibilities.
Building Portable OpenSSH
Dependencies
Portable OpenSSH is built using autoconf and make. It requires a working C compiler, standard library and headers.
libcrypto from either LibreSSL or OpenSSL may also be used. OpenSSH may be built without either of these, but the resulting binaries will have only a subset of the cryptographic algorithms normally available.
zlib is optional; without it transport compression is not supported.
FIDO security token support needs libfido2 and its dependencies and will be enabled automatically if they are found.
In addition, certain platforms and build-time options may require additional dependencies; see README.platform for details about your platform.
Building a release
Releases include a pre-built copy of the configure script and may be built using:
tar zxvf openssh-X.YpZ.tar.gz
cd openssh
./configure # [options]
make && make tests
See the Build-time Customisation section below for configure options. If you plan on installing OpenSSH to your system, then you will usually want to specify destination paths.
Building from git
If building from git, you'll need autoconf installed to build the configure script. The following commands will check out and build portable OpenSSH from git:
git clone https://github.com/openssh/openssh-portable # or https://anongit.mindrot.org/openssh.git
cd openssh-portable
autoreconf
./configure
make && make tests
Build-time Customisation
There are many build-time customisation options available. All Autoconf destination path flags (e.g. --prefix) are supported (and are usually required if you want to install OpenSSH).
For a full list of available flags, run ./configure --help but a few of the more frequently-used ones are described below. Some of these flags will require additional libraries and/or headers be installed.
Non-security bugs may be reported to the developers via Bugzilla or via the mailing list above. Security bugs should be reported to openssh@openssh.com.
