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.)
Closes#11690

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).

I don't think six.iteritems is available here, but I also don't expect
there to be enough platforms to ever make the speed difference between
.items() and .iteritems() noticeable.
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.
Right now, we don't do any locking, but we still scan known_hosts files
twice per connection. That's completely unnecessary, and the proposed
solutions to the locking problem wouldn't need known_hosts scanning
anyway, so this code can go away.
In v1, a trailing newline was kept if the parameter was passed as key=value. If
the parameter was passed as yaml dict the trailing newline was
discarded. Since key-value and yaml dict were unified in v2 we have to
make a choice as to which behaviour we want. Decided that keeping trailing
newlines by default made the most sense.

This information was earlier shown only with ANSIBLE_DEBUG, but it's
extremely useful in a user context, especially with module invocations
with deeply nested args like the ec2_vpc/ec2 modules.

The contributor's name on line 10 (originally line 7) includes a character
that the default Python encoding (ASCII) raises an error on when interpreting
the file.
Specifying the utf-8 encoding, as is done in other modules, resolves
the error.
The error being raised is
SyntaxError: Non-ASCII character '\xc3' in file /.../lib/ansible/module_utils/f5.py
on line 7, but no encoding declared; see http://www.python.org/peps/pep-0263.html

Rewrite function `get_fqdn`. It returns fqdn for all kinds of urls now.
`add_git_host_key` determines whether a url is ssh and whether its host
key should be added.
FieldAttributes will now by default not be post_validated unless a flag
is set on them in the class, as a large number of fields are really there
simply to be inherited by Task/PlayContext and shouldn't be templated too
early.
The other (unrelated to the base issue) in #12084 is also fixed here, where
the roles field is loaded before vars/vars_files, meaning there are no vars
yet loaded in the play when the templating occurs.
Fixes#12084
You cannot call bytes(obj) to get a simple representation of obj on
Python 3! E.g. bytes(42) returns a byte string with 42 NUL characters
instead of b'42'.
Python has had automatic int-to-long promotion for a long long time now.
Even Python 2.4 does that automatically.
Python 3 drops support for the L suffix altogether.
This is based on some code from (closed) PR #7872, but reworked based on
suggestions by @abadger and the other core team members.

Now we issue a "Reading … from stdin" prompt if our input isatty(), as
gpg does. We also suppress the "x successful" confirmation message at
the end if we're part of a pipeline.
(The latter requires that we not close sys.stdout in VaultEditor, and
for symmetry we do the same for sys.stdin, though it doesn't matter in
that case.)
This allows the following invocations:
# Interactive use, like gpg
ansible-vault encrypt --output x
# Non-interactive, for scripting
echo plaintext|ansible-vault encrypt --output x
# Separate input and output files
ansible-vault encrypt input.yml --output output.yml
# Existing usage (in-place encryption) unchanged
ansible-vault encrypt inout.yml
…and the analogous cases for ansible-vault decrypt as well.
In all cases, the input and output files can be '-' to read from stdin
or write to stdout. This permits sensitive data to be encrypted and
decrypted without ever hitting disk.
Now that VaultLib always decides to use AES256 to encrypt, we don't need
this broken code any more. We need to be able to decrypt this format for
a while longer, but encryption support can be safely dropped.
Now we don't have to recreate VaultEditor objects for each file, and so
on. It also paves the way towards specifying separate input and output
files later.
It's unused and unnecessary; VaultLib can decide for itself what cipher
to use when encrypting. There's no need (and no provision) for the user
to override the cipher via options, so there's no need for code to see
if that has been done either.
This commit deprecates the earlier groupname[x-y] syntax in favour of
the inclusive groupname[x:y] syntax. It also makes the subscripting
code simpler and adds explanatory comments.
One problem addressed by the cleanup is that _enumeration_info used to
be called twice, and its results discarded the first time because of the
convoluted control flow.
The possibilities are complicated enough that I didn't want to make
changes without having a complete description of what it actually
accepts/matches. Note that this text documents current behaviour, not
necessarily the behaviour we want. Some of this is undocumented and may
not be intended.
The --new-vault-password-file option works the same as
--vault-password-file but applies only to rekeying (when
--vault-password-file sets the old password). Also update the manpage
to document these options more fully.
`if method in dir(self):` is very inefficient:
- it must construct a list object listing all the object attributes & methods
- it must then perform a O(N) linear scan of that list
Replace it with the idiomatic `if hasattr(self, method):`, which is a
O(1) expected time hash lookup.
Should fix#11981.
Apart from ansible-vault create, every vault subcommand is happy to deal
with multiple filenames, so we can check that there's at least one, and
make create check separately that there aren't any extra.

Now we accept IPv6 addresses _with port numbers_ only in the standard
[xxx]:NN notation (though bare IPv6 addresses may be given, as before,
and non-IPv6 addresses may also be placed in square brackets), and any
other host identifiers (IPv4/hostname/host pattern) as before, with an
optional :NN suffix.
The new code parses INI-format inventory files in a single pass using a
well-documented state machine that reports precise errors and eliminates
the duplications and inconsistencies and outright errors in the earlier
three-phase parsing code (e.g. three ways to skip comments). It is also
much easier now to follow what decisions are being taken on the basis of
the parsed data. The comments point out various potential improvements,
particularly in the area of consistent IPv6 handling.
On the ornate marble tombstone of the old code, the following
inscription is one last baffling memento from a bygone age:
- def _before_comment(self, msg):
- ''' what's the part of a string before a comment? '''
- msg = msg.replace("\#","**NOT_A_COMMENT**")
- msg = msg.split("#")[0]
- msg = msg.replace("**NOT_A_COMMENT**","#")
- return msg
This change is similar to https://github.com/ansible/ansible/pull/10465
It extends the logic there to also support none types. Right now if you have
a '!!null' in yaml, and that var gets passed around, it will get converted to
a string.
eg. defaults/main.yml
```
ENABLE_AWESOME_FEATURE: !!null # Yaml Null
OTHER_CONFIG:
secret1: "so_secret"
secret2: "even_more_secret"
CONFIG:
hostname: "some_hostname"
features:
awesame_feature: "{{ ENABLE_AWESOME_FEATURE}}"
secrets: "{{ OTHER_CONFIG }}"
```
If you output `CONFIG` to json or yaml, the feature flag would get represented in the output
as a string instead of as a null, but secrets would get represented as a dictionary. This is
a mis-match in behaviour where some "types" are retained and others are not. This change
should fix the issue.
I also updated the template test to test for this and made the changes to v2.
Added a changelog entry specifically for the change from empty string to null as the default.
Made the null representation configurable.
It still defaults to the python NoneType but can be overriden to be an emptystring by updating
the DEFAULT_NULL_REPRESENTATION config.
first off, we add an oddly slow basic test of 10k item inventory

This function takes a string like 'foo:bar[1:2]:baz[x:y]-quux' and
returns a list of patterns ['foo', 'bar[1:2]', 'baz[x:y]-quux'], i.e.
splits the string on colons that are not part of a range specification.
get_hosts → used externally, not changed
_get_hosts → _evaluate_patterns (takes a list, evaluates ! and &)

Since we explicitly set convert_bare=False in the template lookup

convert bare variables if needed.
This is a slightly different fix than we originally committed, but fixes
the problem in a less invasive way (and I believe it's generally better
that we don't deal with relative paths internally past this point)

We can unconditionally wrap remote_addr in square brackets for scp and
sftp (both of which require them for IPv6 addresses), but not wrap them
at all for ssh (which doesn't accept them). This way, we don't have to
detect and treat IPv6 addresses specially. This works for hostnames,
IPv4 addresses, and IPv6 addresses.
The earlier code seemed to intend to wrap all IPv6 addresses in square
brackets, which would have broken ssh, but it actually made no attempt
to detect IPv6 addresses at all (so it broke only with IPv6 addresses
for scp and sftp).
