0c3fe8a4e7 This version works
Minimally working version that can link a go program against a so with
the embedded falco engine. Running the program opens the engine for
syscalls and prints any output strings on alert.

It assumes the device already exists and the kernel module is
loaded. Also assumes the lua code is below /user/share--we'll want to
bake that into the shared library.

Lots of memory leaks still, the interface from go to c is still
monolithic, and I had to change the config of openssl crypto and
luajit to compile with -fPIC in order to link into the shared library,
but this version shows its feasible.

c1da6d21b9 new: syscall_event_timeouts configuration block
Falco uses a shared buffer between the kernel and userspace to receive
the events (eg., system call information) in userspace.
Anyways, the underlying libraries can also timeout for various reasons.
For example, there could have been issues while reading an event.
Or the particular event needs to be skipped.
Normally, it's very unlikely that Falco does not receive events consecutively.
Falco is able to detect such uncommon situation.
Here you can configure the maximum number of consecutive timeouts without an event
after which you want Falco to alert.
By default this value is set to 1000 consecutive timeouts without an event at all.

65a168ab5a new(userspace/falco): output msg when the number of consecutive timeouts without an event is greater than a given threshold
The rationale is that in case Falco obtains a consistent number of
consecutive timeouts (in a row) without a valid event, something is
going wrong.

This because, normally, the libs send timeouts to Falco (also) to signal events to discard.
In such cases, which are the majority of cases, `ev` exists and is not
`null`.

46425b392c fix(userspace): handle exceptions for process_k8s_audit_event
This fix has two major points in it:

- when `std::stoll` is used in parse_as_int64 handle all the exceptions it
can throw (https://en.cppreference.com/w/cpp/string/basic_string/stol)
- when `process_k8s_audit_event` an eventual exception in it does not
stop the webserver process. This is done by doing a catch all handle
outside it and by logging an error message to the caller as well as in
stderr

a7e04fe6e6 Add falco engine info to --support output
In some cases, it might be useful to know what falco engine version a
given falco binary supports. We already have a --support option that
prints info about the system, config, rules files, etc.

Add a engine_info object, with an engine_version property containing the
falco engine version in falco_engine_version.h. In the output, it looks
like this:

...
  "engine_info": {
      "engine_version": 8
   },
...

Traditional FIM solutions were not scalable and not working for our environment, but with Falco we found the solution we needed. Falco's detection capabilities have helped us identify anomalous behaviour within our clusters.

* [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended Falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-defined infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.

This change is win-win for both parties because of the following reasons:
- The Falco community owns the source code of the three most important parts of the software it distributes.
- Right now it is "only" an engine on top of the libraries. This **donation** helps in making the scope of the Falco project broader. Having the majority of the source code under an **open governance** in the same organization gives the Falco project more contribution opportunities, helps it in **evolving independently** and makes the whole Falco community a strong owner of the processes and decision making regarding those crucial parts.

/*
This header file provides a C-only interface to the falco engine,
suitable for embedding in other programs as a shared library. This
interface handles:
- Loading Rules Content
- Enabling/Disabling syscall/k8s_audit event sources.
- Loading and configuring source/extractor plugins
- Starting/Stopping the event processing loop.
After setup, the main interface involves receiving "results" when
syscall/k8s_audit/plugin events match rules.
This interface does not provide as many features as the c++
falco_engine interface, such as interfaces to list rules, segregate
rules by "ruleset", enabling/disabling specific rules etc.
Output handling (e.g. routing alerts to files, stdout, webhook,
slack, etc) is not covered by this interface. After receiving a
result, a program could use a program like falcosidekick for a rich
set of output handling methods.
