Share the implementation of hashing for both vars_prompt and password_hash (#21215)
* Share the implementation of hashing for both vars_prompt and password_hash. * vars_prompt with encrypt does not require passlib for the algorithms supported by crypt. * Additional checks ensure that there is always a result. This works around issues in the crypt.crypt python function that returns None for algorithms it does not know. Some modules (like user module) interprets None as no password at all, which is misleading. * The password_hash filter supports all parameters of passlib. This allows users to provide a rounds parameter, fixing #15326. * password_hash is not restricted to the subset provided by crypt.crypt, fixing one half of #17266. * Updated documentation fixes other half of #17266. * password_hash does not hard-code the salt-length, which fixes bcrypt in connection with passlib. bcrypt requires a salt with length 22, which fixes #25347 * Salts are only generated by ansible when using crypt.crypt. Otherwise passlib generates them. * Avoids deprecated functionality of passlib with newer library versions. * When no rounds are specified for sha256/sha256_crypt and sha512/sha512_crypt always uses the default values used by crypt, i.e. 5000 rounds. Before when installed passlibs' defaults were used. passlib changes its defaults with newer library versions, leading to non idempotent behavior. NOTE: This will lead to the recalculation of existing hashes generated with passlib and without a rounds parameter. Yet henceforth the hashes will remain the same. No matter the installed passlib version. Making these hashes idempotent. Fixes #15326 Fixes #17266 Fixes #25347 except bcrypt still uses 2a, instead of the suggested 2b. * random_salt is solely handled by encrypt.py. There is no _random_salt function there anymore. Also the test moved to test_encrypt.py. * Uses pytest.skip when passlib is not available, instead of a silent return. * More checks are executed when passlib is not available. * Moves tests that require passlib into their own test-function. * Uses the six library to reraise the exception. * Fixes integration test. When no rounds are provided the defaults of crypt are used. In that case the rounds are not part of the resulting MCF output.

bugfixes:
|

- vars_prompt with encrypt does not require passlib for the algorithms
|
||||
supported by crypt.
|
||||
- Additional checks ensure that there is always a result of hashing passwords
|
||||
in the password_hash filter and vars_prompt, otherwise an error is returned.
|
||||
Some modules (like user module) interprets None as no password at all,
|
||||
which can be dangerous if the password given above is passed directly into
|
||||
those modules.
|
||||
- Avoids deprecated functionality of passlib with newer library versions.
|
||||
- password_hash does not hard-code the salt-length, which fixes bcrypt
|
||||
in connection with passlib as bcrypt requires a salt with length 22.
|
||||
minor_changes:
|
||||
- The password_hash filter supports all parameters of passlib.
|
||||
This allows users to provide a rounds parameter.

There is an important difference in the way that ``include_role`` (dynamic) will expose the role's variables, as opposed to ``import_role`` (static). ``import_role`` is a pre-processor, and the ``defaults`` and ``vars`` are evaluated at playbook parsing, making the variables available to tasks and roles listed at any point in the play. ``include_role`` is a conditional task, and the ``defaults`` and ``vars`` are evaluated at execution time, making the variables available to tasks and roles listed *after* the ``include_role`` task.

vars_prompt with unknown algorithms
|
||||
-----------------------------------
|
||||
|
||||
vars_prompt now throws an error if the hash algorithm specified in encrypt is not supported by
|
||||
the controller. This increases the safety of vars_prompt as it previously returned None if the
|
||||
algorithm was unknown. Some modules, notably the user module, treated a password of None as
|
||||
a request not to set a password. If your playbook starts erroring because of this, change the

hashing algorithm being used with this filter.

|
|||
|
||||
We are deprecating the use of the ``__file__`` variable to refer to the file containing the currently-running code. This common Python technique for finding a filesystem path does not always work (even in vanilla Python). Sometimes a Python module can be imported from a virtual location (like inside of a zip file). When this happens, the ``__file__`` variable will reference a virtual location pointing to inside of the zip file. This can cause problems if, for instance, the code was trying to use ``__file__`` to find the directory containing the python module to write some temporary information.
|
||||
|
||||
Before the introduction of AnsiBallZ in Ansible 2.1, using ``__file__`` worked in ``AnsibleModule`` sometimes, but any module that used it would fail when pipelining was turned on (because the module would be piped into the python interpreter's standard input, so ``__file__`` wouldn't contain a file path). AnsiBallZ unintentionally made using ``__file__`` always work, by always creating a temporary file for ``AnsibleModule`` to reside in.

|
||||
|
||||
Ansible 2.8 will no longer create a temporary file for ``AnsibleModule``; instead it will read the file out of a zip file. This change should speed up module execution, but it does mean that starting with Ansible 2.8, referencing ``__file__`` will always fail in ``AnsibleModule``.
