For setfacl on Solaris we need to specify permissions like r-x.
For chmod, we need to specify them as rx (r-x means to make the file
readable and *not* executable)
The _fixup_perms2 method checks to see if the user that is being sudo'd
is an unprivileged user or root. If it is an unprivileged user, some
checks are done to see if becoming this user would lock the ssh user out
of temp files, among other things. If this check fails, an error prints
telling the user to check the documentation for becoming an unprivileged
user.
On some systems, the stderr prints out the unprivileged user the ssh
user was trying to become contained in smartquotes. These quotes aren't
in the ASCII range, and so when we're trying to call `str.format()` to
combine the stderr message with the error text we get a
UnicodeEncodeError as python can't coerce the smartquotes using the
system default encoding. By calling `to_native()` on the error message
we can ensure that the error message is a native string for the
`Exception` handling, as `Exception` messages need to be native strings
to avoid errors (byte strings in python2, and text strings in python3)
Fixes: #18444
* 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.
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.
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
Run setfacl/chown/chmod on each temp dir and file.
This fixes temp file permissions handling on platforms such as FreeBSD
which always return success when using find -exec. This is done by
eliminating the use of find when setting up temp files and directories.
Additionally, tests that now pass on FreeBSD have been enabled for CI.
* switch cwd to basedir of task
This restores previous behaviour in pre 2.0 and allows for 'local type' plugins
and actions to have a more predictable relative path.
fixes#14489
* removed FIXME since prev commit 'fixes' this
* fix tests, now they need a loader (thanks jimi!)
* fixed lookup search path
added ansible_search_path var that contains the proper list and in order
removed roledir var which was only used by first_found, rest used role_path
added needle function for lookups that mirrors the action plugin one, now
both types of plugins use same pathing.
* added missing os import
* renamed as per feedback
* fixed missing rename in first_found
* also fixed first_found
* fixed import to match new error class
* fixed getattr ref
* 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
This removes the extra layer of quotes around values in the 'args' file.
These quotes were there before the pipes.quote() call was added, but
were not removed, resulting in too much quoting.
Problem: When setting the file permissions on the remote server for
unprivileged users ansible expects that a chown will fail for unprivileged
users. For some systems (e.g. HP-UX) this is not the case.
Solution: Change the order how ansible sets the remote permissions.
* If the remote_user sudo's to an unprivileged user then we attempt to
grant the unprivileged user access via file system acls.
* If granting file system acls fails we try to change the owner of the
file with chown which only works in case the remote_user is privileged
or the remote systems allows chown calls by unprivileged users (e.g.
HP-UX)
* If the chown fails we can set the file to be world readable so that
the second unprivileged user can read the file. Since this could allow
other users to get access to private information we only do this
ansible is configured with "allow_world_readable_tmpfiles" in the
ansible.cfg
* Give a module the possibility to known its own name
This is useful for logging and reporting and fixes the longstanding problem with syslog-messages:
May 30 15:50:11 moria ansible-<stdin>: Invoked with ...
now becomes:
Jun 1 17:32:03 moria ansible-copy: Invoked with ...
This fixes#15830
* Rename the internal name from module.ansible_module_name to module._name
* Port urls.py to python3
Fixes (largely normalizing byte vs text strings) for python3
* Rework what we do with attributes that aren't set already.
* Comments
* Don't rely on username to check for root privileges
The SSH username isn't a reliable way to check if we've got root privileges on
the remote system (think "toor" on FreeBSD). Because of this check, Ansible
previously tried to use the fallback solutions for granting file access (ACLs,
world-readable files) even on systems where it had root privileges when the
remote username didn't match the literal string "root".
Instead of running checks on the username, just try using `chmod` in any case
and fall back to the previous "non-root" solution when that fails.
* Fail if we are root and changing ownership failed
Since this code is security sensitive we document exactly the expected
permissions of the temporary files once this function has run. That way
if a flaw is found in one end-result we know more precisely what scenarios
are affected and which are not.
action plugins will now skip _fixup_perms for Powershell. We'll have to come up with another way to do this at some point, but it's not necessary yet since we don't support become on Windows. Also added NotImplementedError throws to chmod/chown/set_facl operations on Powershell (instead of returning '') in case anyone tries to use them in the future.
fixes#15312
* 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
The changes to chown/chmod were broken on Mac (-R was being appended to the end of the command- OSX requires it before the file list).
A number of base action remote setup commands were also blindly proceeding without checking for success. Added error raises for unrecoverable failure cases.
