malcontent
|
||
==========
|
||
|
||
malcontent implements support for restricting the abilities of
|
||
non-administrator accounts on a Linux system. Typically, when this is
|
||
used, a non-administrator account will be for a child using the system; and the
|
||
administrator accounts will be for the parents.
|
||
|
||
It provides an
|
||
[accounts-service](https://gitlab.freedesktop.org/accountsservice/accountsservice)
|
||
vendor extension for storing an app filter to
|
||
restrict the child’s access to certain applications; and a simple library for
|
||
accessing and applying the app filter. This results in the policy being stored
|
||
in `/var/lib/AccountsService/users/${user}`, which is a key file readable and
|
||
writable only by the accounts-service daemon. Access to the data is mediated
|
||
through accounts-service’s D-Bus interface, which libmalcontent is a client
|
||
library for
|
||
|
||
All the library APIs are currently unstable and are likely to change wildly.
|
||
|
||
Two kinds of policy are currently supported:
|
||
* A filter specifying whether installed applications are allowed to be run;
|
||
this is typically set up to restrict access to a limited set of
|
||
already-installed applications — but it can be set up to only allow access
|
||
to a fixed list of applications and deny access to all others.
|
||
Applications which are not currently installed are not subject to this
|
||
filter.
|
||
* A set of mappings from [OARS categories](https://hughsie.github.io/oars/) to
|
||
the maximum ratings for those categories which are permissible for a user to
|
||
install apps with. For example, a mapping of `violence-realistic=mild` would
|
||
prevent any applications containing more than ‘mild’ violence from being
|
||
installed. Applications which are already installed are not subject to this
|
||
filter.
|
||
|
||
Additional policies may be added in future.
|
||
|
||
Example usage
|
||
---
|
||
|
||
malcontent ships a `malcontent-client` application which can be used to get and
|
||
set parental controls policies for users.
|
||
|
||
```
|
||
$ # This sets the parental controls policy for user ‘philip’ to allow no \\
|
||
installation of apps with anything more than ‘none’ for realistic violence, \\
|
||
and to blacklist running the org.freedesktop.Bustle flatpak:
|
||
$ malcontent-client set philip \\
|
||
violence-realistic=none \\
|
||
app/org.freedesktop.Bustle/x86_64/stable
|
||
App filter for user 1000 set
|
||
```
|
||
|
||
With that policy in place, other applications which are aware of malcontent will
|
||
apply the policy:
|
||
|
||
```
|
||
$ flatpak run org.freedesktop.Bustle
|
||
error: Running app/org.freedesktop.Bustle/x86_64/stable is not allowed by the policy set by your administrator
|
||
```
