if ANSIBLE_VAULT_PASSWORD_FILE is set, 'ansible-vault rekey myvault.yml'
will fail to prompt for the new vault password file, and will use
None.
Fix is to split out 'ask_vault_passwords' into 'ask_vault_passwords'
and 'ask_new_vault_passwords' to make the logic simpler. And then
make sure new_vault_pass is always set for 'rekey', and if not, then
call ask_new_vault_passwords() to set it.
ask_vault_passwords() would return values for vault_pass and new
vault_pass, and vault cli previously would not prompt for new_vault_pass
if there was a vault_pass set via a vault password file.
Fixes#18247
* Make is_encrypted_file handle both files opened in text and binary mode
On python3, by default files are opened in text mode. Since we know
the encoding of vault files (and especially the header which is the
first set of bytes) we can decide whether the file is an encrypted
vault file in either case.
* Fix is_encrypted_file not resetting the file position
* Update is_encrypted_file to check that all the data in the file is ascii
* For is_encrypted_file(), add start_pos and count parameters
This allows callers to specify reading vaulttext from the middle of
a file if necessary.
* Combine VaultLib.encrypt() and VaultLib.encrypt_bytestring()
* Change vault's is_encrypted() to take either text or byte strings and to return False if any part of the data is non-ascii.
* Remove unnecessary use of six.b
* Vault Cipher: mark a few methods as private.
* VaultAES256._is_equal throws a TypeError if given non byte strings
* Make VaultAES256 methods that don't need self staticmethods and classmethods
* Mark VaultAES and is_encrypted as deprecated
* Get rid of VaultFile (unused and feature implemented in a different way)
* Normalize variable and parameter names on plaintext, ciphertext, vaulttext
* Normalize variable and parameter names on "b_" prefix when dealing with bytes
* Test changes:
* Remove redundant tests( both checking the same byte string)
* Fix use of format string without format operator
* Enable vault editor tests on python3
* Initialize the vault_cipher for VaultAES256 testing in setUp()
* Make assertTrue and assertFalse take the actual method calls for
better error messages.
* Test that non-ascii byte strings compare correctly.
* Test that unicode strings and ints raise TypeError
* Test-specific:
* Removed test_methods_exist(). We only have one VaultLib so the
implementation is the assurance that the methods exist. (Can use an abc for
this if it changes).
* Add tests for both byte string and text string input where the API takes either.
* Convert "assert" to unittest assert functions or add a custom message where
that will make failures easier to debug.
* Move instantiating the VaultLib into setUp().
Later in the stack, further code will check and inform the user that var names must start with a letter
or underscore, so this fix only allows us to get to that previously existing policy.
Fixes#16008
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.
* attempt #11 to role_include
* fixes from jimi-c
* do not override load_data, move all to load
* removed debugging
* implemented tasks_from parameter, must break cache
* fixed issue with cache and tasks_from
* make resolution of from_tasks prioritize literal
* avoid role dependency dedupe when include_role
* fixed role deps and handlers are now loaded
* simplified code, enabled k=v parsing
used example from jimi-c
* load role defaults for task when include_role
* fixed issue with from_Tasks overriding all subdirs
* corrected priority order of main candidates
* made tasks_from a more generic interface to roles
* fix block inheritance and handler order
* allow vars: clause into included role
* pull vars already processed vs from raw data
* fix from jimi-c blocks i broke
* added back append for dynamic includes
* only allow for basename in from parameter
* fix for docs when no default
* fixed notes
* added include_role to changelog
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
This is enough to get minimal copy module working on python3
We have t omodify dataloader's path_dwim_relative_stack and everything
that calls it to use text paths instead of byte string paths
A simple import of cryptography can throw several types of errors. For example,
if `setuptools` is less than cryptography's minimum requirement of 11.3, then
this import of cryptography will throw a VersionConflict here. An earlier case
threw a DistributionNotFound exception.
An optional dependency should not stop ansible. If the error is more than
an ImportError, log a warning, so that errors can be fixed in ansible or
elsewhere.
* smarter function to figure out relative paths
takes list of paths in order of relevance to current task
and does the dwim magic on them
* shared function for action plugins using new dwim
unify path construction and error info/messaging
made include and role non exclusive
corrected order and now smarter about tasks
includes inside roles are currently broken as they don't provide the correct role data
make dirname full match to avoid corner cases
* migrated action plugins to new dwim function
reported plugins to use exceptions instead of info
* clarified needle
* Catch DistributionNotFound when pycrypto is absent
On Solaris 11, module `pkg_resources` throws `DistributionNotFound` on import if `cryptography` is installed but `pycrypto` is not. This change causes that situation to be handled gracefully.
I'm not using Paramiko or Vault, so I my understanding is that I don't
need `pycrpto`. I could install `pycrypto` to make the error go away, but:
- The latest released version of `pycrypto` doesn't build cleanly on Solaris (https://github.com/dlitz/pycrypto/issues/184).
- Solaris includes an old version of GMP that triggers warnings every time Ansible runs (https://github.com/ansible/ansible/issues/6941). I notice that I can silence these warnings with `system_warnings` in `ansible.cfg`, but not installing `pycrypto` seems like a safer solution.
* Ignore only `pkg_resources.DistributionNotFound`, not other exceptions.
rm _del_ as it might leak memory
renamed to tmp file cleanup
added exception handling when traversing file list, even if one fails try rest
added cleanup to finally to ensure removal in most cases
- get_real_file will decrypt vault encrypted files and return a path to
a temporary file.
- cleanup_real_file will remove a temporary file created previously with
get_real_file
Previously, split_args() was not taking print/block/comment depth into account
when splitting things, meaning that if there was a quote character inside an
un-quoted variable (ie. {{ foo | some_filter(' ') }}), it was incorrectly
splitting on the quotes instead of continuing to append to the previous param.
Fixes#13630
Note that this will break if we deal with non-utf8 paths. Fixing this
way because converting everythig to byte strings instead is a very
invasive task so it should be done as a specific feature to provide
support for non-utf8 paths at some point in the future (if needed).
* Changed parse_addresses to throw exceptions instead of passing None
* Switched callers to trap and pass through the original values.
* Added very verbose notice
* Look at deprecating this and possibly validate at plugin instead
fixes#13608
CLI already provides a pager() method that feeds $PAGER on stdin, so we
just feed that the plaintext from the vault file. We can also eliminate
the redundant and now-unused shell_pager_command method in VaultEditor.
Labels must start with an alphanumeric character, may contain
alphanumeric characters or hyphens, but must not end with a hyphen.
We enforce those rules, but allow underscores wherever hyphens are
accepted, and allow alphanumeric ranges anywhere.
We relax the definition of "alphanumeric" to include Unicode characters
even though such inventory hostnames cannot be used in practice unless
an ansible_ssh_host is set for each of them.
We still don't enforce length restrictions—the fact that we have to
accept ranges makes it more complex, and it doesn't seem especially
worthwhile.
This adds a parse_address(pattern) utility function that returns
(host,port), and uses it wherever where we accept IPv4 and IPv6
addresses and hostnames (or host patterns): the inventory parser
the the add_host action plugin.
It also introduces a more extensive set of unit tests that supersedes
the old add_host unit tests (which didn't actually test add_host, but
only the parsing function).
PyYAML has a SafeRepresenter in lib/... that defines
def represent_unicode(self, data):
return self.represent_scalar(u'tag:yaml.org,2002:str', data)
and a different SafeRepresenter in lib3/... that defines
def represent_str(self, data):
return self.represent_scalar('tag:yaml.org,2002:str', data)
so the right thing to do on Python 3 is to use represent_str.
(AnsibleUnicode is a subclass of six.text_type, i.e. 'str' on Python 3.)
Required some rewiring in inventory code to make sure we're using
the DataLoader class for some data file operations, which makes mocking
them much easier.
Also identified two corner cases not currently handled by the code, related
to inventory variable sources and which one "wins". Also noticed we weren't
properly merging variables from multiple group/host_var file locations
(inventory directory vs. playbook directory locations) so fixed as well.
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.
When stretching the key for vault files, use PBKDF2HMAC() from the
cryptography package instead of pycrypto. This will speed up the opening
of vault files by ~10x.
The problem is here in lib/ansible/utils/vault.py:
hash_function = SHA256
# make two keys and one iv
pbkdf2_prf = lambda p, s: HMAC.new(p, s, hash_function).digest()
derivedkey = PBKDF2(password, salt, dkLen=(2 * keylength) + ivlength,
count=10000, prf=pbkdf2_prf)
`PBKDF2()` calls a Python callback function (`pbkdf2_pr()`) 10000 times.
If one has several vault files, this will cause excessive start times
with `ansible` or `ansible-playbook` (we experience ~15 second startup
times).
Testing the original implementation in 1.9.2 with a vault file:
In [2]: %timeit v.decrypt(encrypted_data)
1 loops, best of 3: 265 ms per loop
Having a recent OpenSSL version and using the vault.py changes in this commit:
In [2]: %timeit v.decrypt(encrypted_data)
10 loops, best of 3: 23.2 ms per loop
This is unsafe and we debated re-adding it to the v2/2.0 codebase,
however it is a common-enough feature that we will simply mark it
as deprecated for now and remove it at some point in the future.
