dac99b444c fix(userspace/falco): when collecting metrics for stats_writer, create a libs_metrics_collector for each source.
In case multiple sources are enabled, each source has its own `libs_metrics_collector`
with correct flags, so that it can retrieve all metrics.

Tero Kauppinen
1533734fc4 There is an issue in building the bundled c-ares on certain
distributions such as SLES. The cmake file for c-ares sets
'CARES_LIB' destination directory to '${CARES_SRC}/lib' but when the
bundled c-ares is compiled it produces a binary which is placed in
the '${CARES_SRC}/lib64' directory.

This is due to the fact that the bundled c-ares expands
${CMAKE_INSTALL_LIBDIR} to 'lib64' and not to 'lib' which is
expected by 'CARES_LIB'.

The fix is to enforce the building process of the bundled c-ares
to place the produced binary in 'lib'.

* existing keys will be ignored

6e717daa95 update(userspace/engine): relax validation for values in exceptions
Defining `exceptions` with empty `values` is a legitimate use case since the values can be added to another rules file. Even when values are not populated elsewhere, Falco can work without issues; that's the reason why the `values` field is not required. With this change, we avoid emitting useless validation warnings in situations where exceptions are just defined but not actually used because values are not being provided.

09a9fd4c26 Add tests for mismatched sources and append
Add additional unit tests to verify that rule loading fails when a
second rules object has a different source but the name of an existing
rules object.

Also add tests for additional rules having an empty source.

4a73ef8824 When overriding rules, ensure that the sources match
In places where a second rule definition might replace, append to, or
replace items from a base rule, ensure that the source of the second
rule definiton matches the first.

This already existed for defines, but for other changes. There was a
bug where a second definition might exist for a different source, but
the additional rule was used anyway.

This now returns the same error for these other changes e.g. "Rule has
been re-defined..." as define.

a44b311333 Add a source to rule_update_info
It's possible that someone might want to override a property for a
non-syscall rule source. To assist in this, decode any source property
for rules with append/override and save it in the rule_update_info
object. For the source property only, the value for source can be
empty e.g. 'source: ' or an empty string e.g. 'source: ""'. Both of
those are considered valid but result in an empty source.

A later change will ensure that the sources match up when
appending/redefining/overriding/enabling.

5ba94a36bd fix(falco_metrics): remove ifinfo_json stat/metric
Using JSON as value prevents any meaningful aggregation for the stats.
Splitting these information into multiple labels can drastically
increase the number of dimensions, as the number of interfaces and
addresses can be high in some environment. Moreover, these information
are not currently refreshed, even if they can frequently change. Given
these reasons, remove ifinfo_json from stats and metrics.

## Falco Repo: Powering the Core of The Falco Project
## The Falco Project
This is the main Falco repository which contains the source code for building the Falco binary. By utilizing its [libs](https://github.com/falcosecurity/libs) and the [falco.yaml](falco.yaml) configuration file, this repository forms the foundation of Falco's functionality. The Falco repository is closely interconnected with the following *core* repositories:
The Falco Project codebase is maintained under the [falcosecurity GitHub organization](https://github.com/falcosecurity). The primary repository, [falcosecurity/falco](https://github.com/falcosecurity/falco), holds the source code for the Falco binary, while other sub-projects are hosted in dedicated repositories. This approach of isolating components into specialized repositories enhances modularity and focused development. Notable [core repositories](https://github.com/falcosecurity/evolution?tab=readme-ov-file#core) include:
- [falcosecurity/libs](https://github.com/falcosecurity/libs): Falco's libraries are key to its fundamental operations, making up the greater portion of the source code of the Falco binary and providing essential features such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): Contains the official ruleset for Falco, providing pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins/): Falco plugins facilitate integration with external services, expand Falco's capabilities beyond syscalls and container events, and are designed to evolve with specialized functionality in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): Command-line utility for managing and interacting with Falco.
- [falcosecurity/libs](https://github.com/falcosecurity/libs): This repository hosts Falco's core libraries, which constitute the majority of the binarys source code and provide essential features, such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): It contains the official ruleset for Falco, offering pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins): This repository supports integration with external services through plugins that extend Falco's capabilities beyond syscalls and container events, with plans for evolving specialized functionalities in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): A command-line utility designed for managing and interacting with Falco.
- [falcosecurity/charts](https://github.com/falcosecurity/charts): This repository provides Helm charts for deploying Falco and its ecosystem, simplifying the installation and management process.
For more information, visit the official hub of The Falco Project: [falcosecurity/evolution](https://github.com/falcosecurity/evolution). It provides valuable insights and information about the project's repositories.
For further insights into our repositories and additional details about our governance model, please visit the official hub of The Falco Project: [falcosecurity/evolution](https://github.com/falcosecurity/evolution).
## Getting Started with Falco
Carefully review and follow the [Official Documentation](https://falco.org/docs/install-operate/).
If you're new to Falco, begin your journey with our [Getting Started](https://falco.org/docs/getting-started/) guide. For production deployments, please refer to our comprehensive [Setup](https://falco.org/docs/setup/) documentation.
Considerations and guidance for Falco adopters:
1. Understand dependencies: Assess the environment where you'll run Falco and consider kernel versions and architectures.
2. Define threat detection objectives: Clearly identify the threats you want to detect and evaluate Falco's strengths and limitations.
3. Consider performance and cost: Assess compute performance overhead and align with system administrators or SREs. Budget accordingly.
4. Choose build and customization approach: Decide between the open source Falco build or creating a custom build pipeline. Customize the build and deployment process as necessary, including incorporating unique tests or approaches, to ensure a resilient deployment with fast deployment cycles.
5. Integrate with output destinations: Integrate Falco with SIEM, data lake systems, or other preferred output destinations to establish a robust foundation for comprehensive data analysis and enable effective incident response workflows.
As final recommendations before deploying Falco, verify environment compatibility, define your detection goals, optimize performance, choose the appropriate build, and plan for SIEM or data lake integration to ensure effective incident response.
### Demo Environment
A demo environment is provided via a docker-compose file that can be started on a docker host which includes falco, falcosidekick, falcosidekick-ui and its required redis database. For more information see the [docker-compose section](docker/docker-compose/)

### Examples
**Example 1** Let's consider a feature _foo_ in the Output/Alerts Area introduced in Falco 1.0.0 and labeled as *Incubating*. The feature is promoted to *Stable* in Falco 1.1.0 (because the feature did not get any user-facing change).
Subsequently, maintainers decide that backward-compatible changes must be introduced in _foo_ to improve its functionality. The part of the feature to be changed is labeled as *Deprecated* in Falco 1.2.0, and the deprecation period starts. The non-backward compatible change is then introduced in Falco 1.4.0.
Subsequently, maintainers decide that backward-incompatible changes must be introduced in _foo_ to improve its functionality. The part of the feature to be changed is labeled as *Deprecated* in Falco 1.2.0, and the deprecation period starts. The non-backward compatible change is then introduced in Falco 1.4.0.
**Example 2** The `--bar` flag in the CLI/Config Area has been introduced since Falco 1.1.0 and is labeled as *Stable*. Before releasing Falco 1.5.0, maintainers realize `--bar` is redundant and should be removed. The flag is labeled as *Deprecated* in Falco 1.5.0, and the deprecation period starts. The flag is removed in Falco 1.6.0.
