support plugin-based field extraction with syscall events #410

Closed jasondellaluce closed 1 year ago

jasondellaluce commented 2 years ago

Motivation

Plugins can support the field extraction capability that allow them to add new fields in the engine that can be used in filtering conditions and formatters, such as Falco rules. For example, this is used by the json plugin to support new fields such as json.value[...].

However, the libraries currently do not allow plugins to extract new fields from syscall events. Plugins can extract fields just from event sources implemented by other plugins. As a reference, it is legit for the json plugin to extract values from both the k8saudit and aws_cloudtrail event sources, but not for syscalls (the framework blocks the plugin from receiving those events entirely). This is mostly caused by technical reasons, the first one being the fact that inspecting syscall events would also imply inspecting the libsinsp internal state, for which we don't have a clean interface yet.

Feature

Allow plugins to receive syscall events for field extraction purposes, and support a clean interface for accessing the event data and the related libsinsp state.
