Added iocage connector that extends the jail connector. Uses iocage to translate iocage tags or UUIDs/partial UUIDs to the actual jail name and then uses the jail connector for actual functionality.
Connection plugin can define default action plugin to use by providing
action_handler instance variable. This will override the default
action plugin normal
This adds back the change to the network_cli plugin. Ths change adds
the ensure_connect decorator to the open_shell() method to make sure
the connection is valid before trying to open a shell.
The issue was due to the addition of the decorator that will call
_connect() when there is no connection. The _connect() method should
have been mocked in the test case. This commit fixes the test
case as well
Change was originally reverted in c414ded69a
* removes superfluous timeout kwargs from open_shell()
* cleans up play_context become check
* adds check for ssh session and calls _connect() if needed
Commit ec2521f intended to fix the scp command to fetch files
from a remote machine but it has src and dest swapped.
This change correctly treats src as the location in the remote machine
and dest as the location in the local machine.

This updates the network_cli connection plugin to attempt to automatically
determine the remote device os. The device network os discovery can
be overridden by setting the ansible_network_os value.
* adds new connection plugin `network_cli` which builds on paramiko
* adds new plugin `terminal` used for manipulating network_cli terminals
* adds new field to play_context `network_os` settable as ansible_network_os
This commit adds the plugins necesary to establish a persistent cli connection
to network devices of ssh. It builds on the paramiko connection plugin
to create a shell environment that will persistent through ansible-connection.
The `newtork_cli` plugin then uses the network_os in the instance of
PlayContext to load the appropriate network OS environment plugin for
handling opening and closing of shells as well as privilege escalation.
* updates paramiko_ssh to auto add keys
* updates constants with new config options
This commit adds a new feature that will allow paramiko to automatically
accept and save a host ssh key. This feature is controlled by the
`host_key_auto_add` config setting in the paramiko section. The default
is False to maintain current functionality. It also includes a new
setting `look_for_keys` with the default to False for maintaining current the
current setting.
Fetch module uses fetch_file() from plugin/connection/ssh.py to
retrieve files from the remote hosts which in turns uses
_file_transport_command(self, in_path, out_path, sftp_action) being
sftp_action = 'get'
When using scp rather than sftp, sftp_action variable is not used
and the scp command is formed in a way that the file is always
sent to the remote machine
This patch fixes _file_transport_command() to correctly form the scp
swaping src and dest if sftp_action is 'get'

* Replace pipes.quote for shlex_quote
* More migration of pipes.quote to shlex_quote
Note that we cannot yet move module code over. Modules have six-1.4
bundled which does not have shlex_quote. This shouldn't be a problem as
the function is still importable from pipes.quote. It's just that this
has become an implementation detail that makes us want to import from
shlex instead.
Once we get rid of the python2.4 dependency we can update to a newer
version of bundled six module-side and then we're free to use
shlex_quote everywhere.
* ANSIBLE_SSH_CONTROL_PATH_DIR option added
This removes the hardcoded value ( $HOME/.ansible/cp ) from ssh.py.
User is able to change the ControlPath directory ( the one that replaces %(directory)s ).
Fixes#18325
* Added config option in ansible.cfg
Mitigate the effects of observing the ssh process still running
after seeing an EOF on stdout when using OpenSSH with
ControlPersist, since it does not close the stderr file descriptor
in this case.
Fixes for non-ascii passwords on
* both python2 and python3,
* local and paramiko_ssh (ssh tested working with these changes)
* sudo and su
Fixes#16557
If the sftp fails, roll over to scp by default. This saves users
from having to know about the scp_if_ssh method when sftp is broken
on the remote host.
We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing. So once created it we had two sets of functions that did
the same things but had different implementations. To remedy that, this
change removes the ansible.utils.unicode versions of those functions.
* Fix paramiko's exec_command() to return bytes on python3
* Run test_connection for python3 now too
* Fix atomic_move for problem in shippable's testing
* Python-2.4 needs to use b()
* Fix to_native call in selinux_context and selinux_default_context to
use the error handler correctly.
* Port set_mode_if_different to work on python3
* Port atomic_move to work on python3
* Fix check_password_prompt variable which wasn't renamed properly
The 'import xmltodict' was causing import
errors when generating documentation. Since
xmltodict is a required but not stdlib module,
throw AnsibleError if unable to import.
Remove unused combine_vars.
Replace a use of 'stdin_iterator == None' with
idiomatic 'stdin_iterat is None'
Misc pep8 cleanups.
* Rm py2.7+ code in docker connection plugin
The docker connection plugin was using subprocess.check_output
which only exists in python 2.7 and later. Connection plugins
need to support python2.6 so this replaces it with Popen/communicate()
* Handle docker ver errors in docker connection
Add unit tests for DockerConnection
Fixes#16971
* switch cwd to basedir of task
This restores previous behaviour in pre 2.0 and allows for 'local type' plugins
and actions to have a more predictable relative path.
fixes#14489
* removed FIXME since prev commit 'fixes' this
* fix tests, now they need a loader (thanks jimi!)
This fix prevents a broken pipe exception from occurring when password-less
SSH is configured and the sshpass process exits and closes the pipe before
the password is written to the pipe.
Symlinks inside of the chroot were failng because we weren't able to
determine if they were pointing to a real file or not. We could write
some complicated code to walk the symlink path taking into account where
the root of the tree is but that could be fragile. Since this is just
a sanity check, instead we just assume that the chroot is fine if we
find that /bin/sh in the chroot is a symlink. Can revisit if it turns
out that many chroots have a /bin/sh that's a broken symlink.
Fixes#16097
AIX ssh does not seem to like compression, moved it to ssh_args
to allow making it configurable. Note that those using ssh_args
already will need to add it explicitly to keep compression.
added warnings for invalid kwargs
sniff supported authtypes (for new pywinrm)
use default authtypes (for old pywinrm)
error on unsupported authtype

hacky CLIXML parsing of stderr
Due to an apparent race condition while using pty's on a heavily loaded
system, rarely a request to create a temp directory returns an empty
string rather than the newly created path, causing an error. Disabling
forced pty's appears to resolve the issue, so this patch modifies the
mkdtemp remote call not use -tt as we're not escalating privileges and
thus no pty is required.
Fixes#13876
We were logging the command to be executed many times, which made debug
logs very hard to read. Now we do it only once.
Also makes the logged ssh command line cut-and-paste-able (the lack of
which has confused a number of people by now; the problem being that we
pass the command as a single argument to execve(), so it doesn't need an
extra level of quoting as it does when you try to run it by hand).
Pipelining is a *significant* performance benefit, because each task can
be completed with a single SSH connection (vs. one ssh connection at the
start to mkdir, plus one sftp and one ssh per task).
Pipelining is disabled by default in Ansible because it conflicts with
the use of sudo if 'Defaults requiretty' is set in /etc/sudoers (as it
is on Red Hat) and su (which always requires a tty).
We can (and already do) make sudo/su happy by using "ssh -t" to allocate
a tty, but then the python interpreter goes into interactive mode and is
unhappy with module source being written to its stdin, per the following
comment from connections/ssh.py:
# we can only use tty when we are not pipelining the modules.
# piping data into /usr/bin/python inside a tty automatically
# invokes the python interactive-mode but the modules are not
# compatible with the interactive-mode ("unexpected indent"
# mainly because of empty lines)
Instead of the (current) drastic solution of turning off pipelining when
we use a tty, we can instead use a tty but suppress the behaviour of the
Python interpreter to switch to interactive mode. The easiest way to do
this is to make its stdin *not* be a tty, e.g. with cat|python.
This works, but there's a problem: ssh will ignore -t if its input isn't
really a tty. So we could open a pseudo-tty and use that as ssh's stdin,
but if we then write Python source into it, it's all echoed back to us
(because we're a tty). So we have to use -tt to force tty allocation; in
that case, however, ssh puts the tty into "raw" mode (~ICANON), so there
is no good way for the process on the other end to detect EOF on stdin.
So if we do:
echo -e "print('hello world')\n"|ssh -tt someho.st "cat|python"
…it hangs forever, because cat keeps on reading input even after we've
closed our pipe into ssh's stdin. We can get around this by writing a
special __EOF__ marker after writing in_data, and doing this:
echo -e "print('hello world')\n__EOF__\n"|ssh -tt someho.st "sed -ne '/__EOF__/q' -e p|python"
This works fine, but in fact I use a clever python one-liner by mgedmin
to achieve the same effect without depending on sed (at the expense of a
much longer command line, alas; Python really isn't one-liner-friendly).
We also enable pipelining by default as a consequence.
If we request escalation with a password, we start in expecting_prompt
state. If the escalation then succeeds without the password, i.e., the
become_success response arrives, we must explicitly move into the next
state (awaiting_escalation, which immediately goes into ready_to_send),
so that we no longer try to apply the timeout.
Otherwise, we would leak the success notification and eventually
timeout. But if the module response did arrive before the timeout
expired, the "process has already exited" test would do the right
thing by accident (which is why it didn't fail more often).
Fixes#13289
It was set to match the SSH connect timeout. Unfortunately, they would
race when ssh fails to connect, and the connect timeout usually failed.
This led to some misleading error messages.
Fixes#12916
I PR'd a change to pywinrm to allow server certs to be ignored; but it's only on the SSL transport (which we were previously ignoring). For this to work more generally, we're also now pulling the named ansible_winrm_* args from the merged set of host/group vars, not just host_vars.
also remove condition to bypass setting user if user matches current user
this enables forcing user when set to the same user as current user and ignoring .ssh/config
while keeping .ssh/config with current user if nothing is specified.
When using 'local' connections, privilege escalation would fail if
ansible_ssh_user was in the current context to the same value as
become_user.
This commit ensures that for 'local' connections we reset remote_user to
the local username.
This fixes#12782.
This is because we pass the whole dd command string into the shell
that's running on the contained environment rather than running it
directly from python via subprocess without a shell.
The earlier code behaved exactly as though this default had been set,
but it was actually handled as a(n unnecessary) special case inside the
connection plugin, rather than set as an explicit default.
If the default is overriden either in ansible.cfg or the environment,
the new code will continue to work (in fact, it won't know or care,
since it just uses the value set in the PlayContext).
This is submitted as a separate commit for easier review to address
backwards-compatibility concerns.
Using set_host_overrides() in the connection plugin to access the ssh
argument variables from the inventory didn't see group_vars/host_vars
settings, as noted earlier. Instead, we can set the correct values in
the PlayContext, which has access to all command-line options, task
settings, and variables.
The only downside of doing so is that the source of the settings is no
longer available in ssh.py, and therefore can't be logged. But the code
is simpler, and it actually works.
This change was suggested by @jimi-c in response to the FIXME in the
earlier commit.
Now we have the following ways to set additional arguments:
1. [ssh_connection]ssh_args in ansible.cfg: global setting, prepended to
every command line for ssh/scp/sftp. Overrides default ControlPersist
settings.
2. ansible_ssh_common_args inventory variable. Appended to every command
line for ssh/scp/sftp. Used in addition to ssh_args, if set above, or
the default settings.
3. ansible_{sftp,scp,ssh}_extra_args inventory variables. Appended to
every command line for the relevant binary only. Used in addition to
#1 and #2, if set above, or the default settings.
3. Using the --ssh-common-args or --{sftp,scp,ssh}-extra-args command
line options (which are overriden by #2 and #3 above).
This preserves backwards compatibility (for ssh_args in ansible.cfg),
but also permits global settings (e.g. ProxyCommand via _common_args) or
ssh-specific options (e.g. -R via ssh_extra_args).
