Adrian Likins c38ff3b8f8 pylint fixes for vault related code (#27721)
* rm unneeded parens following assert
* rm unused parse_vaulttext_envelope from yaml.constructor
* No longer need index/enumerate over vault_ids
* rm unnecessary else
* rm unused VaultCli.secrets
* rm unused vault_id arg on VaultAES.decrypt()

pylint: Unused argument 'vault_id'
pylint: Unused parse_vaulttext_envelope imported from ansible.parsing.vault
pylint: Unused variable 'index'
pylint: Unnecessary parens after 'assert' keyword
pylint: Unnecessary "else" after "return" (no-else-return)
pylint: Attribute 'editor' defined outside __init__

* use 'dummy' for unused variables instead of _

Based on pylint unused variable warnings.

Existing code use '_' for this, but that is old
and busted. The hot new thing is 'dummy'. It
is so fetch.

Except for where we get warnings for reusing
the 'dummy' var name inside of a list comprehension.

* Add super().__init__ call to PromptVaultSecret.__init__
pylint: __init__ method from base class 'VaultSecret' is not called (super-init-not-called)

* Make FileVaultSecret.read_file reg method again

The base class read_file() doesnt need self but
the sub classes do.

Rm now unneeded loader arg to read_file()

* Fix err msg string literal that had no effect
pylint: String statement has no effect

The indent on the continuation of the msg_format was wrong
so the second half was dropped.

There was also no need to join() filename (copy/paste from
original with a command list I assume...)

* Use local cipher_name in VaultEditor.edit_file not instance
pylint: Unused variable 'cipher_name'
pylint: Unused variable 'b_ciphertext'

Use the local cipher_name returned from parse_vaulttext_envelope()
instead of the instance self.cipher_name var.

Since there is only one valid cipher_name either way, it was
equilivent, but it will not be with more valid cipher_names

* Rm unused b_salt arg on VaultAES256._encrypt*
pylint: Unused argument 'b_salt'

Previously the methods computed the keys and iv themselves
so needed to be passed in the salt, but now the key/iv
are built before and passed in so b_salt arg is not used
anymore.

* rm redundant import of call from subprocess
pylint: Imports from package subprocess are not grouped

use via subprocess module now instead of direct
import.

* self._bytes is set in super init now, rm dup

* Make FileVaultSecret.read_file() -> _read_file()

_read_file() is details of the implementation of
load(), so now 'private'.

Adrian Likins 934b645191 Support multiple vault passwords (#22756)
Fixes #13243

** Add --vault-id to name/identify multiple vault passwords

Use --vault-id to indicate id and path/type

 --vault-id=prompt  # prompt for default vault id password
 --vault-id=myorg@prompt  # prompt for a vault_id named 'myorg'
 --vault-id=a_password_file  # load ./a_password_file for default id
 --vault-id=myorg@a_password_file # load file for 'myorg' vault id

vault_id's are created implicitly for existing --vault-password-file
and --ask-vault-pass options.

Vault ids are just for UX purposes and bookkeeping. Only the vault
payload and the password bytestring is needed to decrypt a
vault blob.

Replace passing password around everywhere with
a VaultSecrets object.

If we specify a vault_id, mention that in password prompts

Specifying multiple -vault-password-files will
now try each until one works

** Rev vault format in a backwards compatible way

The 1.2 vault format adds the vault_id to the header line
of the vault text. This is backwards compatible with older
versions of ansible. Old versions will just ignore it and
treat it as the default (and only) vault id.

Note: only 2.4+ supports multiple vault passwords, so while
earlier ansible versions can read the vault-1.2 format, it
does not make them magically support multiple vault passwords.

use 1.1 format for 'default' vault_id

Vaulted items that need to include a vault_id will be
written in 1.2 format.

If we set a new DEFAULT_VAULT_IDENTITY, then the default will
use version 1.2

vault will only use a vault_id if one is specified. So if none
is specified and C.DEFAULT_VAULT_IDENTITY is 'default'
we use the old format.

** Changes/refactors needed to implement multiple vault passwords

raise exceptions on decrypt fail, check vault id early

split out parsing the vault plaintext envelope (with the
sha/original plaintext) to _split_plaintext_envelope()

some cli fixups for specifying multiple paths in
the unfrack_paths optparse callback

fix py3 dict.keys() 'dict_keys object is not indexable' error

pluralize cli.options.vault_password_file -> vault_password_files
pluralize cli.options.new_vault_password_file -> new_vault_password_files
pluralize cli.options.vault_id -> cli.options.vault_ids

** Add a config option (vault_id_match) to force vault id matching.

With 'vault_id_match=True' and an ansible
vault that provides a vault_id, then decryption will require
that a matching vault_id is required. (via
--vault-id=my_vault_id@password_file, for ex).

In other words, if the config option is true, then only
the vault secrets with matching vault ids are candidates for
decrypting a vault. If option is false (the default), then
all of the provided vault secrets will be selected.

If a user doesn't want all vault secrets to be tried to
decrypt any vault content, they can enable this option.

Note: The vault id used for the match is not encrypted or
cryptographically signed. It is just a label/id/nickname used
for referencing a specific vault secret.

Adrian Likins 4befefd78c Try to show original exception info for yaml (and other) errors (#24468)
* show original exception for yaml (and other) errors

In places where we need to catch a yaml error and raise
an AnsibleError, add the orig yaml exc to the AnsibleError
via the orig_exc arg.

When the AnsibleError is displayed it will now include the
AnsibleError (AnsibleParserError for example) and the type
and message from the original yaml exception.

This provides more detail to the error messages related to
yaml errors.

This also improves errors from dataloader (for example,
previously if a wrong password was used for a vault encrypted
yaml file, the error was very vague and suggested yaml errors,
but now the message includes the original exception from vault
indicating the password was incorrect or missing).

Add a text note to playbook helper asserts. For playbook
syntax/layout errors that aren't yaml errors, but errors
indicating invalid data structures for a playbook/task/role/block,
we now include some info about where the assert was and
why it was raised.

In places we raise an AnsibleParserError in an except
clause, pass the original exception to AnsibleParserError via
orig_exc arg.

Make assorted error messages a little more specific (like
the playbook helper load methods)

* Revert "Include the original YAML error in syntax error messages"

This reverts commit 781bb44b02.

Toshio Kuratomi 1c05ed7951 Fix circular import with unsafe_proxy, template, and vars
template/__init__.py imported unsafe_proxy from vars which caused
vars/__init__.py to load.  vars/__init__.py needed template/__init__.py
which caused issues.  Loading unsafe_proxy from another location fixes
that.

Adrian Likins edcbef27ec Retain vault password as bytes in 2.2 (#22378)
* Retain vault password as bytes in 2.2

Prior to 2.2.1, the vault password was read in as byes and then remained
bytes all the way through the code.  A bug existed where bytes and text
were mixed, leading to a traceback with non-ascii passwords.  In devel,
this was fixed by changing the read in password to text type to match
with our overall strategy of converting at the borders.  This was
backported to stable-2.2 for the 2.2.1 release.

On reflection, this should not have been backported as it causes
passwords which were originally non-utf-8 to become utf-8.  People will
then have their working 2.2.x vault files become in-accessible.

this commit pipes bytes all the way through the system for vault
password.  That way if a password is read in as a non-utf-8 character
sequence, it will continue to work in 2.2.2+.  This change is only for
the 2.2 branch, not for 2.3 and beyond.

Why not everywhere?  The reason is that non-utf-8 passwords will cause
problems when vault files are shared between systems or users.  If the
password is read from the prompt and one user/machine has a latin1
encoded locale while a second one has utf-8, the non-ascii password
typed in won't match between machines.  Deal with this by making sure
that when we encrypt the data, we always use valid utf-8.

Fixes #20398

Toshio Kuratomi 4ed88512e4 Move uses of to_bytes, to_text, to_native to use the module_utils version (#17423)
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.

Adrian Likins e396d5d508 Implement vault encrypted yaml variables. (#16274)
Make !vault-encrypted create a AnsibleVaultUnicode
yaml object that can be used as a regular string object.

This allows a playbook to include a encrypted vault
blob for the value of a yaml variable. A 'secret_password'
variable can have it's value encrypted instead of having
to vault encrypt an entire vars file.

Add __ENCRYPTED__ to the vault yaml types so
template.Template can treat it similar
to __UNSAFE__ flags.

vault.VaultLib api changes:
    - Split VaultLib.encrypt to encrypt and encrypt_bytestring

    - VaultLib.encrypt() previously accepted the plaintext data
      as either a byte string or a unicode string.
      Doing the right thing based on the input type would fail
      on py3 if given a arg of type 'bytes'. To simplify the
      API, vaultlib.encrypt() now assumes input plaintext is a
      py2 unicode or py3 str. It will encode to utf-8 then call
      the new encrypt_bytestring(). The new methods are less
      ambiguous.

    - moved VaultLib.is_encrypted logic to vault module scope
      and split to is_encrypted() and is_encrypted_file().

Add a test/unit/mock/yaml_helper.py
It has some helpers for testing parsing/yaml

Integration tests added as roles test_vault and test_vault_embedded
