* 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.
* 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.
Two parts to this change:
* Add a new string that requests password
* Add a new glyph that can be used to separate the prompt from the
user's input as it seems it can use fullwidth colon rather than colon.
Fixes#17867
The -b option reads as follows:
` The target job is directed to ignore hangup signals. This is particularly
useful for running the target program in the background.`
If needed, '-b' can be added to become_flags

move -b to pbrun_flags
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
Implement tag and skip_tag handling in the CLI() class. Change tag and
skip_tag command line options to be accepted multiple times on the CLI
and add them together rather than overwrite.
* Make it configurable whether to merge or overwrite multiple --tags arguments
* Make the base CLI class an abstractbaseclass so we can implement
functionality in parse() but still make subclasses implement it.
* Deprecate the overwrite feature of --tags with a message that the
default will change in 2.4 and go away in 2.5.
* Add documentation for merge_multiple_cli_flags
* Fix galaxy search so its tags argument does not conflict with generic tags
* Unit tests and more integration tests for tags
Working on the test suite, I tried to replace a call to sudo to a
call to su, and found out that I can't change user to 'nobody'
without changing the option become_flags in ansible.cfg
As this would be dependent on the user and the task, it make more sense
to push the setting there.
* add check_mode option for tasks
includes example testcases for the template module
* extend check_mode option
* replace always_run, see also proposal rename_always_run
* rename always_run where used and add deprecation warning
* add some documentation
* have check_mode overwrite always_run
* use unique template name to prevent conflicts
test_check_mode was right before, but failed due to using the same filename as other roles
* still mention always_run in the docs
* set deprecation of always_run to version 2.4
* fix rst style
* expand documentation on per-task check mode
* Ziploader proof of concept (jimi-c)
* Cleanups to proof of concept ziploader branch:
* python3 compatible base64 encoding
* zipfile compression (still need to enable toggling this off for
systems without zlib support in python)
* Allow non-wildcard imports (still need to make this recusrsive so that
we can have module_utils code that imports other module_utils code.)
* Better tracebacks: module filename is kept and module_utils directory
is kept so that tracebacks show the real filenames that the errors
appear in.
* Make sure we import modules that are used into the module_utils files that they are used in.
* Set ansible version in a more pythonic way for ziploader than we were doing in module replacer
* Make it possible to set the module compression as an inventory var
This may be necessary on systems where python has been compiled without
zlib compression.
* Refactoring of module_common code:
* module replacer only replaces values that make sense for that type of
file (example: don't attempt to replace python imports if we're in
a powershell module).
* Implement configurable shebang support for ziploader wrapper
* Implement client-side constants (for SELINUX_SPECIAL_FS and SYSLOG)
via environment variable.
* Remove strip_comments param as we're never going to use it (ruins line
numbering)
* Don't repeat ourselves about detecting REPLACER
* Add an easy way to debug
* Port test-module to the ziploader-aware modify_module()
* strip comments and blank lines from the wrapper so we send less over the wire.
* Comments cleanup
* Remember to output write the module line itself in powershell modules
* for line in lines strips the newlines so we have to add them back in
Prior to 75b6f61, we strictly limited variables we re-injected. After that
patch however, we re-injected everything which causes problems under certain
circumstances. For now, we'll continue to filter out some properties of
PlayContext for re-injection.
Fixes#14352
* If the internal value is None, do not add the variable
* Make sure all aliases for a given variable name are set (if they're
not already set in the dictionary)
Fixes#14310
* Don't re-use the existing connection if the remote_addr field of
the play context has changed
* When overriding variables in PlayContext (from task/variables),
don't set the same attribute based on a different variable name
if we had already previously set it from another variable name
Fixes#13880
moved from the field attribute declaration and created a placeholder
which then is resolved in the field attribute class.
this is to avoid unwanted persistent of the defaults across objects which introduces
stealth bugs when multiple objects of the same kind are used in succession while
not overriding the default values.
tasks were overriding commandline with their defaults, not with the
explicit setting, removed the setting of defaults from task init and
pushed down to play context at last possible moment.
fixes#13362
For some situations like Vagrant, the remote_addr may be a localhost addr, but ssh
is still desired. This corrects the assumption that any localhost remote_addr should
be using the local connection by checking the inventory_hostname value as well.
Fixes#12817
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).
Fixes#12576
SSH pipelining can be a significant performance improvement, but it will
not work if sudoers is configured to requiretty. With this change, one
could have pipelining enabled in ansible.cfg, but use sudo to turn off
requiretty in a separate play (or task) where pipelining is disabled:
- hosts: foo
vars:
ansible_pipelining: no
tasks:
- lineinfile: dest=/etc/sudoers line='Defaults requiretty' state=absent
sudo_user: root
(Note that sudoers has a complicated syntax, so the above lineinfile
invocation may be too simplistic for production use; but the point is
that a separate play can do something to disable requiretty.)
* allow global no_log setting, no need to set at play or task level, but can be overriden by them
* allow turning off syslog only on task execution from target host (manage_syslog), overlaps with no_log functionality
* created log function for task modules to use, now we can remove all syslog references, will use systemd journal if present
* added debug flag to modules, so they can make it call new log function conditionally
* added debug logging in module's run_command
Due to the way we're now calculating delegate_to, if that value is based
on a loop variable ('item') we need to calculate all of the possible
delegated_to variables for that loop.
Fixes#12499
The event loop (even after it was brought into one place in _run in the
previous commit) was hard to follow. The states and transitions weren't
clear or documented, and the privilege escalation code was non-blocking
while the rest was blocking.
Now we have a state machine with four states: awaiting_prompt,
awaiting_escalation, ready_to_send (initial data), and awaiting_exit.
The actions in each state and the transitions between then are clearly
documented.
The check_incorrect_password() method no longer checks for empty strings
(since they will always match), and check_become_success() uses equality
rather than a substring match to avoid thinking an echoed command is an
indication of successful escalation. Also adds a check_missing_password
connection method to detect the error from sudo -n/doas -n.
Now, instead of relying on hostvars on the executor side, we compile
the vars for the delegated to host in a special internal variable and
have the PlayContext object look for things there when applying task/
var overrides, which is much cleaner and takes advantage of the code
already dealing with all of the magic variable variations.
Fixes#12127Fixes#12079
Use six.moves.range instead (aliased to xrange on Python 2, aliased to
range on Python 3).
Also I couldn't resist replacing the elaborate chr/ord/randrange dance
with the simpler random.choice(string.ascii_lowercase) that was already
used elsewhere in the Ansible codebase.

Don't disable GSSAPI/Pubkey authentication when using --ask-pass
This commit is based on a bug report and PR by kolbyjack (#6846) which
was subsequently closed and rebased as #11690. The original problem was:
«The password on the delegated host is different from the one I
provided on the command line, so it had to use the pubkey, and the
main host doesn't have a pubkey on it yet, so it had to use the
password.»
(This commit is revised and included here because #11690 would conflict
with the changes in #11908 otherwise.)

Be more explicit about why SSH arguments are added
This adds vvvvv log messages that spell out in detail where each SSH
command-line argument is obtained from.
Unfortunately, we can't be sure if, say, self._play_context.remote_user
is obtained from ANSIBLE_REMOTE_USER in the environment, remote_user in
ansible.cfg, -u on the command line, or an ansible_ssh_user setting in
the inventory or on a task or play. In some cases, e.g. timeout, we
can't even be sure if it was set by the user or just a default.
Nevertheless, on the theory that at five v's you can use all the hints
available, I've mentioned the possible sources in the log messages.
Note that this caveat applies only to the arguments that ssh.py adds by
itself. In the case of ssh_args and ssh_extra_args, we know where they
are from, and say so, though we can't say WHERE in the inventory they
may be set (e.g. in host_vars or group_vars etc.).

Allow ansible_ssh_args to be set as an inventory variable
Before this change, ssh_args could be set only in the [ssh_connection]
section of ansible.cfg, and was applied to all hosts. Now it's possible
to set ansible_ssh_args as an inventory variable (directly, or through
group_vars or host_vars) to selectively override the global setting.
Note that the default ControlPath settings are applied only if ssh_args
is not set, and this is true of ansible_ssh_args as well. So if you want
to override ssh_args but continue to set ControlPath, you'll need to
repeat the appropriate options when setting ansible_ssh_args.
(If you only need to add options to the default ssh_args, you may be
able to use the ansible_ssh_extra_args inventory variable instead.)

Allow overriding ansible_ssh_extra_args on the command-line
This patch makes it possible to do:
ansible somehost -m setup \
--ssh-extra-args '-o ProxyCommand="ssh -W %h:%p -q user@bouncer.example.com"'
This overrides the inventory setting, if any, of ansible_ssh_extra_args.
Based on a patch originally by @Richard2ndQuadrant.

Add an ansible_ssh_extra_args inventory variable
This can be used to configure a per-host or per-group ProxyCommand to
connect to hosts through a jumphost, e.g.:
inventory:
[gatewayed]
foo ansible_ssh_host=192.0.2.1
group_vars/gatewayed.yml:
ansible_ssh_extra_args: '-o ProxyCommand="ssh -W %h:%p -q bounceuser@gateway.example.com"'
Note that this variable is used in addition to any ssh_args configured
in the [ssh_connection] section of ansible.cfg (so you don't need to
repeat the ControlPath settings in ansible_ssh_extra_args).
Replace .iteritems() with six.iteritems() everywhere except in
module_utils (because there's no 'six' on the remote host). And except
in lib/ansible/galaxy/data/metadata_template.j2, because I'm not sure
six is available there.
The lock file is (a temporary file) opened in the parent process, whose
open fd is inherited by the workers after fork, and passed down through
the PlayContext. Connection grows lock/unlock methods which can be used
by individual connection plugins.
* now it uses -n to get immediate error if no password is supplied and one is needed,
this should fix the issue with sudo hanging waiting for input.
* made -k configurable, this can break changing become_users in play if left out,
but opens up the possiblity of OTP support.
* added pattern matching to match v1 functionality
* check the task name, not the task+role name for matches
* make sure the input is unicode
Fixes#11692
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
