+# How to contribute
+
+## Enforce coding style 💻
+
+### Introduction
+
+This document introduces the coding style that will be applied in this repository.
+This coding style involves all the following files: `.c`, `.h`, `.cpp`, `.cmake`, `CMakeLists.txt`. To enforce it we rely on two main tools:
+
+1. `clang-format` version `18.1.8`.
+2. `cmake-format` version `0.6.13`.
+
+> __Please note__: tools versions are important! Different versions will enforce slightly different changes on the code. For example `clang-format-18` will produce a slightly different output respect to `clang-format-17` always respecting the imposed style.
+
+The coding style is expressed through the 2 configuration file that you find in this repo: `.clang-format`, `.cmake-format.json`.  
+
+### Enforce the style locally
+
+There are many ways to enforce the style locally, here we will describe two of them:
+
+1. Use `pre-commit` framework.
+2. Use the repo `Makefile`.
+
+#### 1.Pre-commit framework (suggested if you don't have the 2 tools already installed on your machine)
+
+The `pre-commit` framework allows you to automatically install different `git-hooks` that will run at every new commit. More precisely, if you use the `.pre-commit-config.yaml` in this repo you will install 3 different hooks:
+
+1. The `clang-format` hook: this is a `pre-commit` git hook that runs `clang-format` on your staged changes.
+2. The `cmake-format` hook: this is a `pre-commit` git hook that runs `cmake-format` on your staged changes.
+3. The `DCO signed-off` hook: this is a `pre-commit-msg` git hook that adds the `DCO` on your commit if not present. This hook is not strictly related to the coding style so we will talk about it in a separate section: [Add DCO signed-off to your commits](#add-dco-signed-off-to-your-commits-).
+
+Now let's see what we need to use `pre-commit` framework.
+
+##### Step 1
+
+Install `pre-commit` framework following the [official documentation](https://pre-commit.com/#installation).
+
+> __Please note__: you have to follow only the "Installation" section.
+
+##### Step 2
+
+Once you have installed `pre-commit`, you don't need to install anything else! This is the good point of using a framework like `pre-commit`, all the tools necessary to format your code will be directly managed by the framework. But in order to be ready, you need to install the git hooks in your local repo.
+
+This simple command allows you to install the two `pre-commit` git hooks, `clang-format` and `cmake-format`.
+
+```bash
+pre-commit install --install-hooks --hook-type pre-commit --overwrite  
+```
+
+If you want to install also the `pre-commit-msg` git hook for the DCO you have to type the following command, but be sure to have configured all you need as said in the [dedicated section](#add-dco-signed-off-to-your-commits-)
+
+```bash
+pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite 
+```
+
+You have done, at every new commit, this hook will check that your patch respects the coding style of this repo!
+
+If you want to detach the git hooks, you can simply type:
+
+```bash
+pre-commit uninstall --hook-type prepare-commit-msg
+pre-commit uninstall --hook-type pre-commit 
+```
+
+#### 2.Makefile
+
+##### Step 1
+
+In order to use the repo `Makefile`, you need to install on your local machine the two aforementioned tools:
+
+__clang-format v18.1.8__
+
+One of the easiest ways to install `clang-format` could be directly downloading its static binary from [here](https://github.com/muttleyxd/clang-tools-static-binaries).
+There are other ways for example you can download the package for your distro or you can also build it from sources.
+
+__cmake-format v0.6.13__
+
+To install `cmake-format` you can follow the official documentation [here](https://cmake-format.readthedocs.io/en/latest/installation.html).
+
+> __NOTE__: Please check the versions of the two tool with `clang-format --version` and `cmake-format --version`.
+
+##### Step 2
+
+Once you have installed the __right__ versions of the 2 tools, you can simply type `make format-all` from the root directory of the project to format all your code according to the coding style.
+
+Remember to do that before submitting a new patch upstream! 😁
+
+#### Other solutions
+
+Obviously, you can also install the 2 tools locally and enable some extension of your favorite IDE (like `VScode`) to format your code every time you save your files!
+
+## Add DCO signed-off to your commits 🔏
+
+### Introduction
+
+Another requirement for contributing to the `falco` repository, is applying the [DCO](https://cert-manager.io/docs/contributing/sign-off/) to every commit you want to push upstream.
+Before doing this you have to configure your git user `name` and `email` if you haven't already done it. To check your actual `name` and `email` type:
+
+```bash
+git config --get user.name
+git config --get user.email
+```
+
+If they are correct you have done, otherwise, you have to set them:
+
+```bash
+git config user.name <full-name>
+git config user.email <mail-used_with-GitHub-profile>
+```
+
+>__Please note__: If you have problems in doing this you can read the full documentation [here](https://docs.github.com/en/get-started/getting-started-with-git/setting-your-username-in-git).
+
+### Enforce the DCO locally
+
+Now you are ready to sign your commits! You have two main ways to do this:
+
+1. Manually with `git` tool.
+2. Use the `pre-commit-msg` hook quoted before.
+
+### Manually
+
+To do this you just need to remember the `-s` while performing your commits:
+
+```bash
+git commit -s
+```
+
+or with the inline message:
+
+```bash
+git commit -s -m "my first commit"
+```
+
+### Use `pre-commit` hook
+
+Here if you have already added the hook in the [previous section](#step-2), you have to do nothing otherwise you have to simply install the DCO hook with:
+
+```bash
+pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite 
+```
+
+And you have done! Now you don't have to remember the `-s` option every time you commit something, the DCO hook will automatically add the DCO if you forget it! 😄
+
+## Some best practices 📏
+
+### Class variables
+
+To know whether a variable belongs to a `class` or a `function`, we start member variables with `m_`.
+
+Example:
+
+```c
+    public int32_t m_counter;
+```
+
+### Global variables
+
+To know whether the variable is global or not, we start globals with `g_`.
+
+Example:
+
+```c
+    int g_nplugins;
+```
+
+### Capitalization
+
+The naming convention is camel-cased "Unix" style, i.e. always lower case. Words are separated by underscores.
+
+Example:
+
+```c
+    int32_t g_global_bean_counter;
+    int32_t count_beans();
+```
+
+and not,
+
+```c
+    int32_t GlobalBeanCounter;
+    int32_t CountBeans();
+```
+
+### Packed Structures
+
+Packed structures should use the GCC and MSVC-style supported `pragma`:
+
+Example:
+
+```c
+    #pragma pack(push,1)
+    struct frame_control
+    {
+        struct fields....
+    };
+    #pragma pack(pop)
+```
+
+### 64-bit constants
+
+Put an `LL` at the end of your `64-bit` constants. Without the `LL`, some platform compilers try to interpret the constant on the right-hand side as a `long integer` instead of a `long long` and this could lead to an error at building time.
+
+Example:
+
+```c
+    x=0X00FF00000000000LL
+```

 ## Getting Started with Falco
 
-Carefully review and follow the [official guide and documentation](https://falco.org/docs/getting-started/).
+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:
+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.
 
-1. Understand dependencies: Assess the environment where you'll run Falco and consider kernel versions and architectures.
+### Demo Environment
 
-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.

-## Why is Falco in C++ rather than Go or {language}?
+Falco's [Build Falco from source](https://falco.org/docs/developer-guide/source/) is the go-to resource to understand how to build Falco from source. In addition, the [falcosecurity/libs](https://github.com/falcosecurity/libs) repository offers additional valuable information about tests and debugging of Falco's underlying libraries and kernel drivers.
+
+Here's an example of a `cmake` command that will enable everything you need for all unit tests of this repository:
+
+```bash
+cmake \
+-DUSE_BUNDLED_DEPS=ON \
+-DBUILD_DRIVER=ON \
+-DBUILD_FALCO_MODERN_BPF=ON \
+-DCREATE_TEST_TARGETS=ON \
+-DBUILD_FALCO_UNIT_TESTS=ON ..;
+```
+
+Build and run the unit test suite:
+
+```bash
+nproc=$(grep processor /proc/cpuinfo | tail -n 1 | awk '{print $3}');
+make -j$(($nproc-1)) falco_unit_tests;
+# Run the tests
+sudo ./unit_tests/falco_unit_tests;
+```
+
+Optionally, build the driver of your choice and test run the Falco binary to perform manual tests.
+
+Lastly, The Falco Project has moved its Falco regression tests to [falcosecurity/testing](https://github.com/falcosecurity/testing).

 1. The first lines of code at the base of Falco were written some time ago, where Go didn't yet have the same level of maturity and adoption as today.
 2. The Falco execution model is sequential and mono-thread due to the statefulness requirements of the tool, and so most of the concurrency-related selling points of the Go runtime would not be leveraged at all.
-3. The Falco code deals with very low-level programming in many places (e.g. some headers are shared with the eBPF probe and the Kernel module), and we all know that interfacing Go with C is possible but brings tons of complexity and tradeoffs to the table.
+3. The Falco code deals with very low-level programming in many places, and we all know that interfacing Go with C is possible but brings tons of complexity and tradeoffs to the table.
 4. As a security tool meant to consume a crazy high throughput of events per second, Falco needs to squeeze performance in all hot paths at runtime and requires deep control on memory allocation, which the Go runtime can't provide (there's also garbage collection involved).
 5. Although Go didn't suit the engineering requirements of the core of Falco, we still thought that it could be a good candidate for writing Falco extensions through the plugin system. This is the main reason we gave special attention and high priority to the development of the plugin-sdk-go.
 6. Go is not a requirement for having statically-linked binaries. In fact, we provide fully-static Falco builds since few years. The only issue with those is that the plugin system can't be supported with the current dynamic library model we currently have.

 9. Memory safety is definitely a concern and we try our best to keep an high level of quality even though C++ is quite error prone. For instance, we try to use smart pointers whenever possible, we build the libraries with an address sanitizer in our CI, we run Falco through Valgrind before each release, and have ways to stress-test it to detect performance regressions or weird memory usage (e.g. https://github.com/falcosecurity/event-generator). On top of that, we also have third parties auditing the codebase by time to time. None of this make a perfect safety standpoint of course, but we try to maximize our odds. Go would definitely make our life easier from this perspective, however the tradeoffs never made it worth it so far due to the points above.
 10. The C++ codebase of falcosecurity/libs, which is at the core of Falco, is quite large and complex. Porting all that code to another language would be a major effort requiring lots of development resource and with an high chance of failure and regression. As such, our approach so far has been to choose refactors and code polishing instead, up until we'll reach an optimal level of stability, quality, and modularity, on that portion of code. This would allow further developments to be smoother and more feasibile in the future.

 - Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
 - [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax and loading logic, and/or when `FALCO_ENGINE_CHECKSUM` has changed. The checksum is computed by considering the available rules fields (see currently supported [Falco fields](https://falco.org/docs/reference/rules/supported-fields/)), the event types (see currently supported [Falco events](https://falco.org/docs/reference/rules/supported-events/)), and the supported driver schema version. A checksum indicates that something was not available in previous engine versions. See the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md#versioning-a-ruleset) to understand how this affects the versioning of Falco rules. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The version number must be incremented every time and only when a single change or an atomic group of changes - which meet the criteria described above - is included in the `master` branch. Thus, a version bump can occur multiple times during the development and testing phases of a given release cycle. A given version bump must not group multiple changes that occurred sporadically during the release cycle.
 - During development and release preparation, libs and driver reference commits are often bumped in Falco's cmake setup ([falcosecurity-libs cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/falcosecurity-libs.cmake#L30) and [driver cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/driver.cmake#L29)) in order to merge new Falco features. In practice, they are mostly bumped at the same time referencing the same `libs` commit. However, for the official Falco build `FALCOSECURITY_LIBS_VERSION` flag that references the stable libs version is used (read below).
-- Similarly, Falco plugins versions are bumped in Falco's cmake setup ([plugins cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/plugins.cmake)) and those versions are the ones used for the Falco release.
 - At release time Plugin, Libs and Driver versions are compatible with Falco.
-- If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with (read more below under Libs).

+# Warning
+
+This environment is provided for demonstration purposes only and does not represent a production ready deployment of Falco.
+
+# Components
+The components that this docker-compose file spins up are [Falco](https://falco.org/), [falcosidekick](https://github.com/falcosecurity/falcosidekick), [falcosidekick-ui](https://github.com/falcosecurity/falcosidekick-ui) and a [redis](https://redis.io/) database.
+
+# Running
+To start this environment run `docker-compose up`.
+Note: You may need to use sudo for Falco to start correctly.
+
+# Cleaning up
+
+To clean up run `docker-compose rm`.
+
+# Generating events
+If you'd like to generate events that will trigger rules and show up in the UI you can run `docker run -it --rm falcosecurity/event-generator run syscall --loop`

+# On Host Anomaly Detection Framework - New `anomalydetection` Plugin
+
+## Motivation
+
+**A Wind of Change for Threat Detection**
+
+Feel that light breeze? That is the continued advancement of cloud native security blowing steady. But despite our progress, threat actors are outpacing our innovation constantly finding new ways to thwart and tornado past our achievements — rule-based detections focus on what we *think* attackers will do, not on what they *are* doing and generate enough alerts to bury security analysts in a sandstorm of poor signal-to-noise. Can this dynamic be blown back to shift the information asymmetry in favor of defenders?
+
+This framework lays the foundation on how to create high-value, kernel signals that are difficult to bypass - but not in the traditional way. Advanced data analytics is an emerging crosswind that enables us to soar past attackers by detecting deviations in current behavior from past behavior. 
+
+## Benefits to the Ecosystem
+
+Advanced data analytics enables us to combine the intricacies of the Linux kernel with on-host anomaly detection in cloud native and cloud environments to determine patterns of past behavior in running applications. By detecting deviations in current behavior from past behavior, we can shift the focus away from relying solely on signatures and rule matching to catch attackers.
+
+Threat detection in open source and more importantly cloud native is constrained by the amount of rules we can write and the signatures we know to look for in our environments. But these have the same problem: they assume our attackers don't change what they're doing. The reality is attackers are not limited to the ways, means, and methods they employ to expose, manipulate, or even destroy our data, systems, and organizations. 
+
+This framework leverages an attacker's mindset applied to detection engineering: observing and learning about our targets to create more rich and actionable alerts so we can catch them earlier and more often - regardless if it's behavior we know about, or something we haven't seen yet.
+
+## Elevator Pitch
+
+When Falco processes events in userspace, its rules engine filters the events while the parsers simultaneously update and maintain an internal state. This state includes a process tree cache that enhances Falco alerts by providing contextual information derived from previous events. The goal is to enhance the "state engine" even further and provide an option for monitoring the behavior of applications over time.
+
+To achieve this, end users define a "behavior profile" in the configuration by combining existing event fields such as process name, file descriptor (fd), executable path, parent lineage, cmdline, and others. During event parsing on the hot path, Falco compresses and stores this information in a "filter" - an efficient probabilistic data structure that optimizes space, time, robustness and accuracy. As time progresses, Falco provides more accurate estimates of application behavior counts and identifies events as rare or heavy hitters. Instead of analyzing the original event stream, you can write Falco rules based on pre-filtered data. 
+
+This approach introduces a novel threat detection framework that analyzes abnormal application behavior in real-time, derived and observed in a data-driven fashion, without requiring operator reconfiguration of Falco. It complements the operator's expertise and extends capabilities similar to our current practices. The new capability draws inspiration from big data stream and database query optimizations, ensuring that Falco maintains a streamlined real-time one-pass stream with zero allocations.
+
+Similar to Falco rules, the analysis of events may require multiple behavior profiles of different dimensions based on sets of events. These profiles can either vote in parallel or in a cascading fashion, a common practice in established algorithms. This is just the beginning and and paves the way for more sophisticated approaches, such as running Falco in a DAST-like capacity to build a pre-state pattern file on a workload with test data and soften the cold-start via distributing it to production.
+
+## Challenges and Considerations
+
+First, The Falco Project is committed to continuously ensuring access to the most accurate data possible for on-host threat detection. As an example, recent efforts involved expanding kernel signal logging, such as verifying if an execve call is linked to a file descriptor existing exclusively in memory or improving the efficient and reliable resolution of symlinks for executable paths. Therefore, the proposed anomaly detection framework operates under the assumption of having the *correct* data, thereby complementing the ongoing efforts to expand logging coverage and improve its quality. In summary, the primary focus of the framework is to derive increased value from the existing *right* data that is currently available.
+
+There is a common perception that attacks on running cloud applications, as well as their indicators of compromise, are typically rare when the appropriate data or combination of signals is considered. While this holds true, there are inherent challenges in applying this concept of rarity to robust data analytics approaches. 
+
+On the one hand, this is due to the diverse range of attacks and attack vectors. An attacker may introduce a new malicious binary (which is comparatively easier to detect using traditional rules and high-value kernel signals) after gaining initial access. Alternatively, they may exploit existing binaries, shell built-ins, and employ obfuscation techniques to "live off the land". The Turing completeness of the latter scenario, in particular, leads to an infinite number of attack possibilities.
+
+However, what poses even more challenges in anomaly detection lies not necessarily in the nature of attacks but rather in identifying the right signals and their appropriate combinations for robust analytics to distinguish between normal and anomalous behavior. This challenge becomes particularly evident when considering the natural fluctuations in application behavior over time and the occurrence of ad-hoc legitimate debugging activities. Such fluctuations can arise from various factors, including routine deployment updates. Moreover, certain applications may produce random file names or execute arbitrary executable paths as part of their regular operations, adding to the challenge of anomaly detection. This is compounded by the inherent "cold start" issue when initially observing an application. In such cases, the algorithms must demonstrate flexibility and robustness by recognizing and encoding consistent patterns, similar to how humans can identify the sameness by examining combinations of file names, command arguments, parent process lineage, and other attributes. Furthermore, factors like data inconsistency and the diverse forms of data representations (comprising a mix of numeric data and strings with varying meanings) further complicate the task.
+
+We believe it is important to incorporate operator heuristics or domain knowledge into the algorithm's definition of rarity. For example, while current algorithms are capable of generating human faces, they used to frequently produce images with different eye colors. However, if we were to inform the machine that humans typically have matching eye colors, it could easily correct this discrepancy. This highlights the role of the security engineer as a guiding hand to the algorithms, both in terms of handling noise tolerance and choosing the appropriate data to be ingested into the algorithm. This is crucial as machines are currently limited in their ability to draw meaningful observations from limited data and constrained memory. In summary, this is where the fusion of data-driven anomaly detection and rules matching will come into play.
+
+Lastly, the value proposition of conducting real-time anomaly analysis on the host lies in the unique options it offers, which cannot be achieved through alternative methods. On the host, we can observe anomalies based on all relevant and observed kernel events. In contrast, sending a large volume of kernel events to a centralized system would be impractical, resulting in significant costs for data pipeline management and data lake compute expenses.
+
+## Initial Scope
+
+The initial scope is to implement the Count Min Sketch algorithm using n shared sketches and expose its count estimates as new filterchecks for use in Falco rules. An MVP can be explored in this libs draft PR [wip: new(userspace/libsinsp): MVP CountMinSketch Powered Probabilistic Counting and Filtering](https://github.com/falcosecurity/libs/pull/1453). Moreover, the initial anomaly detection framework will include a transparent `plugin` user interface for defining application behavior profiles and utilizing sketch count estimates in Falco rules. The primary direct benefit lies in establishing a safety boundary for Falco rules in production environments, allowing for broader rule monitoring while preventing Falco rules from blowing up in production.
+
+Furthermore, The Falco Project will provide adopters with valuable initial use cases, recommended thresholds, and callouts for known issues. One important consideration is the identification of SRE anti-patterns. Another consideration is to provide *very clear* guidance to adopters for setting and configuring parameters, including recommended minimums. Additionally, guidance should be provided on indicators to look for in order to determine if adjustments need to be made and in which direction, particularly when defining application behavior profiles.
+
+## High-Level Technical Design of a New `anomalydetection` Plugin
+
+This document provides a high-level proposal with limited technical details.
+
+*Probabilistic Data Structures*
+
+One option for implementing the probabilistic filter is by utilizing a robust two-dimensional probabilistic data structure known as the Count Min Sketch. This data structure is widely employed in distributed stream processing frameworks such as Apache Spark, Apache Storm, Apache Flink, and others, as well as databases like Redis and PostgreSQL.
+
+Technical details and implications are extensively covered in numerous research papers and textbooks. Therefore, here are some key points to consider in order to make informed choices:
+
+- The challenges posed by both hard and soft collisions can be mitigated by using multiple non-cryptographic hash functions, which has been mathematically proven to be effective.
+- Despite providing one-sided error bounds and preventing undercounting, the sketchy data structure requires adopters to define a tolerance level for overcounting. This tolerance level determines what qualifies as rare or noteworthy.
+- To enhance accuracy and reduce estimation errors, consider debiasing data (e.g. Count Min Sketch with Conservative Updates) or applying a logarithmic scale to address kernel event data skew. The logarithmic scale may suit threat detection, targeting low-frequency or long-tail attack-related items. However, only use if performance overhead is acceptable.
+- Use larger shared sketches and incorporate container IDs as part of the behavior profiles to differentiate between workloads / applications. Conversely, use separate sketches for distinct behavior profiles, also known as the "what we are counting".
+- ... and numerous other aspects that will be discussed in subsequent implementation PRs.
+
+*Plumbing and Interface*
+
+The ultimate goal is to introduce these new capabilities as plugin. A significant amount of work will be dedicated to addressing the necessary plumbing required to support the new framework and integrate it with the existing rules filtering, `libsinsp` and `plugin` mechanisms. This integration aims to provide a user-friendly interface that allows users to easily configure and utilize the opt-in framework for different use cases. 
+
+For instance, the interface should empower end users to define error tolerances and, consequently, sketch dimensions, along with other tuning parameters, bounds, and settings. Ultimately, it should enable the definition of n behavior profiles to facilitate the use of count estimates in Falco rules.
+
+## What this Framework is Not
+
+- This framework is not intended to function as an event aggregator or enhancer, such as netflow data. Its sole purpose is to serve as an anomaly filter for individual events, utilizing the existing sinsp state, the newly built state through sketches, and the current rules engine.
+- The development of this framework will not be swayed by overly specific use cases that limit its broader adoption and coverage.
+- While it may not offer flawless attack threat detection from the beginning, it serves as an initial step towards comprehensive event logging and analysis, capturing all events that exhibit any form of new or changing behavior we observe. Therefore, initially, the greatest value lies in combining it with regular Falco rules based on the anomaly-filtered event stream.
+
+## Why now?
+
+In case you haven't noticed, advanced data analytics is quite the big deal these days, and we can leverage robust established algorithms used in real production settings across various industries. The novelty lies in addressing the specific data encoding challenges unique to the field of cybersecurity, not re-inventing already established algorithms.
+
+Furthermore, over the past several Falco releases, we have significantly improved stability, configurability, and capabilities. Notably, the plugins system has been refined over the past year to efficiently access the complete `libsinsp` state, now also featuring an improved CPP SDK. Additionally, it now seamlessly collaborates with the existing primary syscalls event source, deviating from its original purpose of processing new data sources. This improvement allows for more intuitive functionality, as demonstrated by the new `k8smeta` plugin. Now is the opportune time to further enhance proven threat detection capabilities and expand the plugins system even more. 
+
+*Initial community feedback concerning the KubeCon NA 2023 Full Talk*
+
+- Overall, the feedback for [A Wind of Change for Threat Detection](https://kccncna2023.sched.com/event/1R2mX/a-wind-of-change-for-threat-detection-melissa-kilby-apple) was very positive and appreciative, particularly regarding the direct real-life benefits (a safety boundary for Falco rules enabling broader monitoring that won't blow up in production). Suggestions for future development included integrating the sketch directly into the kernel driver (which would be a remarkable achievement if feasible). Lastly, people have inquired about the timeline for the availability of this feature.
+- Refer to the [KubeCon NA 2023 Slides](https://static.sched.com/hosted_files/kccncna2023/c5/A%20Wind%20of%20Change%20for%20Threat%20Detection%20-%20Melissa%20Kilby%20-%20KubeCon%20NA%202023.pdf) or [attached PDF](kubeconna23-anomaly-detection-slides.pdf) for more information. Here's the [Talk Recording](https://www.youtube.com/watch?v=1y1m9Vz93Yo) (please note that the first four minutes of the video are missing, but the slides and audio recordings are complete).
+
+*Falco Community Call - January 17, 2024*
+
+See dedicated [HackMD](https://hackmd.io/Ss0_1avySUuxArBQm-oaGQ?view):
+
+- While not blocking the start of the plugin or an alpha dev version, there's feedback from @jasondellaluce that plugins cannot access the existing `libsinsp` filtercheck. It would be advantageous to enable this access to avoid reimplementing them and the constant risk of falling out of sync with `libs`. @leogr mentioned that supporting this over time should be possible.
+- We have discussed the plugins config and are currently undecided on whether the definition of the behavior profile per sketch, meaning the fields that are string concatenated together and counted, should reside in the plugins config or in the rules files. The latter would potentially require a new rules component. Final decisions will be deferred to a later stage to ensure the config is intuitive, and we want to guarantee proper sketch definition when attempting to run Falco rules using the `anomalydetection` plugin.  
+- One use case, namely determining if a rule has previously occurred in a container, could be addressed by this framework as well. However, we are currently unsure how to expose the rule names, as `libsinsp` is not aware of them. This may be an optimization we can address later and does not block the development of an initial version.
+- Future use cases might involve counting distinct values, utilizing the hyper log log algorithm. However, there will be additional technical challenges to overcome.
+- Finally, just to reiterate some feedback from the KubeCon talk, there's a suggestion that, perhaps in the future, we could pass intelligence back and forth between the drivers and userspace. This idea has been discussed independently, especially in the context of kernel-side filtering. However, such capabilities would be a long-term consideration.

+# Features Adoption and Deprecation Policies Proposal
+
+This proposal aims to introduce a balance between maintaining adopter trust and the need for The Falco Project to evolve. Historically, Falco has favored rapid evolution over providing long-term support for features and interfaces. However, some project subsystems have been implicitly assumed not to allow backward-incompatible changes (e.g., we have almost never removed a condition syntax field). These implicit conventions have never been formalized, and decisions in this regard have been left unspecified.
+
+## Goals
+
+- Establish adopter expectations on the operational cost of using Falco.
+- Provide a clear path for features to be adopted and dismissed.
+- Allow quick evolution and experimentation without disrupting our adopters' deployments.
+- Detail the process for introducing new features, following a "sandbox" to "incubating" to "stable" progression.
+- Define the scope of the policy, including which aspects of Falco are covered (e.g., command line flags, configuration files, rules syntax).
+- Establish stages for deprecating features, aligning with the project's current status (pre- and post-1.0 stages).
+- Adopt a semantic versioning (semver) approach.
+
+## Non-Goals
+
+- Define the number of previous releases that will receive patches or security updates and the duration of this support.
+- Define the criteria for Falco 1.0.
+
+## Scope
+
+The proposed policies apply to Falco, its subsystems (e.g., rules, the plugin system), and all [core projects](https://github.com/falcosecurity/evolution#core) which are deemed [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable), thus officially supported by The Falco Project.
+
+## Definitions
+
+### Feature Changes
+
+A feature is a distinct and specific functionality or characteristic of Falco and its core components that provides value to the user by enabling them to perform particular tasks. Features encompass aspects such as functionality, user value, usability, integrability, scalability, configurability, and discoverability. Features can range from essential user interface elements to complex, multifunctional operations.
+
+A feature change refers to any modification or update to an existing feature or the addition of a new feature. This does not include documentation, Falco compatibility across different environments, platforms, systems, or other software or hardware, bug fixing (stated it does not require a feature change to overcome the problem), and performance (unless a change produces a measurable effect on usability).
+
+### Behavior Changes
+
+A behavior change refers to alterations in how Falco, or a specific feature within it, operates or responds under certain conditions. Unlike feature changes, behavior changes are more about tweaking the underlying logic or the way existing features interact or perform, particularly the expected behavior of Falco when run with the default configuration.
+
+Behaviors are generally documented. Any modification that does not meet the conditions and expectations of an already documented feature is assumed to be a behavior change.
+
+Undocumented behaviors may be included in this definition if there's strong evidence or suspicion that users rely on those undocumented behaviors.
+
+### User-Facing Changes
+
+User-facing changes refer to any feature changes, behavior changes, modifications, or additions that are directly noticeable and interactable by the end users. These changes affect how Falco operates from the user's perspective (notably any change that can lead to user disruption). Unlike internal changes (i.e., code refactoring, CI, maintenance-related changes), which are under-the-hood improvements not directly visible to the user, user-facing changes are evident in the Falco and its core components interface and functionality.
+
+### CLI/Config Area
+
+Falco is comprised of the Falco binary and other programs and tools cooperating (notably [falcoctl](https://github.com/falcosecurity/falcoctl)). These programs are the primary user interface for Falco. Any feature or behavior changes to the following elements of these programs are assumed to be user-facing changes to the CLI/Config area:
+
+- Program name.
+- Distribution mechanism and packaging (e.g., a container image).
+- Command line flags and options.
+- Environment variables.
+- Configurations.
+- Elements that affect the program's lifecycle (e.g., the effect of sending a SIGINT to the program).
+- Elements that allow scripting, automation, or interaction with other programs (e.g., piping and redirection).
+- Program inputs, excluding elements explicitly governed by other areas (e.g., [Falco rules](#rules-area)).
+- Program outputs excluding elements explicitly governed by other areas (e.g., [Falco outputs/alerts](#outputs-alerts-area)).
+
+### Rules System Area
+
+Rules are the primary input for Falco. Any feature or behavior changes to the following aspects or elements are assumed to be user-facing changes to the rules system area:
+
+- Syntax.
+- File format.
+- Schema (i.e., supported fields).
+- Elements that affect the way users can implement rules.
+- Elements that affect the way rules are triggered.
+
+However, any change related to the rule's output when triggered (i.e., the alert) is out of scope for this area (see next section).
+
+Note that this area does not include changes related to the ruleset files. Ruleset distributions follow their own [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) policies. 
+
+### Outputs/Alerts Area
+
+Alerts, delivered through Falco output channels, are Falco's primary output. The way and the format in which alerts are produced can have a significant impact on adopters. For example, removing a supported rule field also impacts this area, as adopters may have relied on that field when consuming Falco output.
+
+Any feature or behavior changes to the following aspects or elements are assumed to be user-facing changes to the Outputs/Alerts area:
+
+- Output and logging formats.
+- Schema of outputted data (i.e., supported fields).
+- Falco output channels.
+- Any element that might be consumed from the output.
+
+### Subsystem APIs (Plugins, gRPC Output, Metrics, etc.) Area
+
+Falco is also comprised of several subsystems providing specific APIs. These subsystems notably include plugin system API, gRPC output API, and metrics API.
+
+In the context of this proposal, only changes to **public APIs** are assumed to be user-facing changes to this area.
+
+Public APIs are defined as those supporting Falco functioning and explicitly intended for user usage. Internal APIs consumed by Falco or other tools are out of scope for this area. For instance, the driver APIs or libs APIs are intended to be mainly consumed by Falco and not by users.
+
+### Platform Support Area
+
+Platform support for Falco encompasses the range of platforms, systems, and environments it is designed to operate in. Platform support may significantly vary by Falco's data sources and use cases. For example, its compatibility differs when utilized for Kubernetes audit events versus system call events. Additionally, platform support can be influenced by deployment methods (e.g., directly on a host versus within Kubernetes) or configurations (e.g., running in privileged versus least privileged mode).
+
+Given the diversity of potential platforms and setups, only those explicitly listed in Falco's documentation are considered officially supported. While Falco may function on other platforms, official support is guaranteed solely for documented ones.
+
+Therefore, changes in platform compatibility or behavior that are documented explicitly assumed to be user-facing changes to the Platform Support area.
+
+### Release Cycle
+
+In the context of this proposal, a release cycle is the period between two consecutive major or minor releases of Falco. Hotfix/Patch releases must not be counted.
+
+The actual duration of a release cycle can vary. Still, it's assumed to be about 16 weeks (as per our current defined [Release Cycles and Development Iterations](https://github.com/falcosecurity/falco/blob/master/proposals/20230511-roadmap-management.md#release-cycles-and-development-iterations)). In case of future modification to the Falco release schedule, a period of minimum 3 months must be assumed.
+
+## Proposal
+
+### Maturation Levels
+
+Maturation levels (inspired by those we already have in place for [repositories](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#status)) are used to characterize the maturity of a feature. Each feature will have an assigned level  at any specific time (i.e., a Falco release). Levels are shown in the table below.
+
+| Maturity Level | Intended for |
+| --- | --- |
+| Sandbox |  Experimental/alpha features, not recommended for production use, can be removed at any time without further notice. |
+| Incubating | Beta features, long-term support is not guaranteed. |
+| Stable | General Availability (GA) features for which long-term support is expected. |
+| Deprecated | See the [deprecation policy](#Deprecation-policy) section below. |
+
+### Adoption Policy
+
+The adoption policy applies to any backward compatible user-facing changes which add functionalities. For non-backward compatible changes see the [deprecation policy](#Deprecation-policy) below.
+
+**Adoption rules**:
+1. A feature can be introduced at only one of the following levels:
+   - Sandbox: The feature must be opt-in (e.g., not enabled by default), labeled as *Sandbox* and the user must be proactively informed by the experimental nature of the feature (i.e. emitting a notice when the feature is being enabled).
+   - Incubating: The feature must be labeled as *Incubating*.
+2. Any functionality additions to an existing feature are inherently introduced at the same level as the feature itself unless logically separable (for instance, a sub-feature that may be enabled separately).
+3. A feature can be promoted *from Sandbox to Incubating* or *from Incubating to Stable* only after at least one release cycle has passed without user-facing changes to the feature.
+4. A feature cannot be demoted to a previous level.
+
+
+_Note about behaviors_:
+This policy indirectly applies to behaviors, too. Behavior changes are assumed to be a consequence of a feature change. The adoption level of a documented behavior is considered to be the same as the related feature. Furthermore, behavior changes are particularly relevant in the context of deprecation (see the next section).
+
+
+### Deprecation Policy
+
+The deprecation policy applies to any non-backward compatible user-facing changes. Any other changes introduced in a backward-compatible manner does not fall under the scope of this deprecation policy.
+
+**Deprecation rules**:
+1. Sandbox features can be removed or changed at any time without notice. No deprecation period is required.
+2. Incubating or Stable features and documented behaviors must enter a deprecation period and function for no less than the indicated release cycles (see tables below) after their announced deprecation. 
+   - If the change affects the feature partially, the deprecation applies only to that feature part. 
+   - If the change removes the feature entirely, the deprecation applies to the entire feature.
+3. At least for the entire deprecation period, the feature must be labeled as *Deprecated* in all relevant documentation, and:
+   - for deprecated configurations or CLI elements, a warning must be emitted warnings when the feature is being enabled or used;
+   - for deprecated APIs, when technically feasible, the API should be signal the deprecation status (this may vary depending on the specific subsystem);
+   - for deprecated behaviors the documentation must highlight the _before_ and _after_ behavior, alongside with a prominent deprecation notice.
+4. Any Pull Request introducing a deprecation notice must be labeled and include a note in the format `DEPRECATION NOTICE: ...`.
+5. Any Pull Request introducing a breaking change due to the end of the deprecation notice period must be labeled and include a note in the format `BREAKING CHANGE: ...`. 
+   - It is also recommended for code commits that introduce a breaking change to follow the related [conventional commit spec](https://www.conventionalcommits.org/en/v1.0.0/#specification).
+
+The minimum deprecation period length depends on the affected area. If a single change spans multiple areas, the area with the most extended deprecation period is assumed. Longer deprecation periods are allowed if the feature is deemed to be particularly critical or widely used.
+
+#### Deprecation Period Lengths
+
+_The units represent the number of releases._
+
+##### Before Falco 1.0
+
+| Area           | Stable | Incubating |
+| -------------- | ------ | ---------- |
+| *all areas*    | 1      | 0          |
+
+##### Since Falco 1.0 onward
+
+| Area           | Stable | Incubating |
+| -------------- | ------ | ---------- |
+| Behaviors      | 2      | 1          |
+| Rules System   | 2      | 1          |
+| Output/Alerts  | 2      | 1          |
+| Platform       | 2      | 1          |
+| CLI/Config     | 1      | 1          |
+| Subsystem APIs | 1      | 0          |
+
+### 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-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.
+
+### Exceptions
+
+- Ruleset in the official distributions follow the [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) policies.
+- Subsystems or subcomponents may have additional criteria and exceptions. Stated other criteria and exceptions must not directly affect the main Falco distribution (e.g., *falcoctl* can have a different release cycle and different policies; however, if Falco relies on a specific *falcoctl* feature, that *falcoctl* feature adoption and deprecation must be strictly compatible with the rules described in this proposal).
+- Internal APIs are out of scope for this policy. Their adoption models and deprecation policies might be regulated separately.
+- Different parties may provide plugins, and each plugin may have a different maturity level. Only those plugins officially maintained by The Falco Project and identified as "core" for Falco are in scope for this policy; all others are excluded.
+- Any other exceptions to the rules provided by this policy require a formal core maintainer majority vote.
+
+### Versioning
+
+Regarding the above policies, component versioning must adhere to [Semantic Versioning 2.0.0](https://semver.org/). However, in the context of Falco core components, the scope extends beyond the strict API definition and includes any user-facing changes.
+
+Thus, given a version number `MAJOR.MINOR.PATCH` increment the:
+
+- *MAJOR* version when the deprecation period of one or more _stable_ features ends, thus introducing incompatible user-facing or API changes.
+- *MINOR* version when adding functionality in a backward-compatible manner.
+- *PATCH* version when making backward-compatible bug fixes.
+
+Moreover, *MAJOR* version zero (0.y.z) is for versioning stabilization (i.e., before defining the public set of user-facing features and APIs). At this stage, the *MINOR* version is allowed to be incremented instead of the *MAJOR* version.
+
+### Documentation
+
+Documentation must be tied to a specific release and reflect the adoption level status of a feature at that specific release. In particular:
+
+- Deprecated items must be labeled `DEPRECATED` in all relevant documentation.
+- Stable items must be sufficiently documented. Explicitly labeling the Stable status is not required or recommended.
+- Incubating items must be sufficiently documented and labeled  `INCUBATING` in all relevant documentation.
+- Sandbox items may be partially documented and labeled `SANDBOX` in all relevant documentation, if any. The relevant documentation must also explicitly state the experimental nature of the item.
+
+## Transition Phases
+
+Since software components may need to adapt to implement the requirements this proposal mandates, we assume the following stages are required to transition from the current state to the desired state fully:
+
+- Within Falco 0.38, at least stable features must be identified, and the adoption policy and relevant documentation should be implemented in Falco. Exceptions may be made temporarily for the deprecation policy.
+- Within subsequent releases and no later than Falco 1.0.0 (still not scheduled to date), all the policies must be strictly implemented in Falco and documented in [falco.org](falco.org). The [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) must be adapted to ensure it aligns with the spirit of this proposal. Exceptions may be made temporarily for other [core projects](https://github.com/falcosecurity/evolution#core) with [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable) status, assuming exceptions don't severely affect the main Falco distribution.
+- Within Falco 1.1.0, all the policies must be strictly implemented in Falco and in all [core projects](https://github.com/falcosecurity/evolution#core) with [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable) status.
+
+During the transition phases, maintainers can fine-tune these policies and add further exceptions, eventually. After this initial transition phases, the policy is assumed to be established. From then on, any policy modifications, updates, and exceptions must be subject to a core maintainer majority vote to ensure the policy remains relevant and practical.

+# Multi-Threaded Falco High-Level Design (Working draft)
+
+## Summary
+
+This document outlines a high-level design for implementing multi-threading in Falco. The goal of this proposal is to overcome Falco's single-threaded architecture to improve scalability in scenarios where the amount of events produced cannot be processed in a single thread. This is achieved by leveraging multiple threads for event processing, rule evaluation, and output handling, enabling Falco to better utilize multi-core systems and reduce event drops under high event rates.
+
+## Goals
+
+* Address the problems related to single CPU core saturation, leading to dropped events.
+* Minimize the performance impact on the single threaded usage, that remains the default. 
+
+## Non-Goals
+
+* This document does not cover low-level implementation details that will be addressed in specific design documents for each component or directly in the implementation phase.
+* This document does not focus on performance optimization, the primary goal is scalability improvements to handle higher event rates that exceed single-thread processing capacity.
+
+## Success Metrics
+
+The success of this multi-threading initiative will be measured by the following key metrics:
+
+* **Event Drop Rate Reduction**: The primary success metric is the reduction in event drops under high event rates. A successful implementation should significantly reduce or eliminate event drops that occur when a single thread cannot keep up with the event rate.
+* **Throughput Scaling**: The system should demonstrate improved throughput (events processed per second) that scales with the number of worker threads, up to a reasonable limit based on available CPU cores and workload characteristics.
+* **CPU Utilization**: Multi-threaded Falco should better utilize available CPU cores, with worker threads distributing load across multiple cores instead of saturating a single core.
+* **Single-Threaded Performance Preservation**: The single-threaded mode (default) should maintain its current performance characteristics, with minimal or no performance regression when multi-threading is disabled.
+
+These metrics will be evaluated through benchmarking and real-world deployment scenarios to validate that the multi-threaded architecture achieves its scalability goals without compromising correctness or introducing significant overhead.
+
+## High-Level Design
+
+### Current Architecture
+
+![Current Falco Architecture](images/falco-architecture.png)
+
+* The kernel driver (via kmod or eBPF) writes events into per-CPU ring buffers. Each CPU has its own buffer to avoid lock contention. We have a ring buffer per CPU core, and a single userspace.
+* Userspace (libscap) performs an `O(n_cpus)` scan on every next() call, it peeks at the head event from each ring buffer, finds the event with the minimum timestamp across all buffers and returns that event to Falco for processing. The consumer position is only advanced after the event has been consumed (on the next call), ensuring the caller can safely read the event data and avoiding the need to perform copies of the event data.
+* Libsinsp processes the events sequentially as they are received from libscap, building a stateful representation of the system and providing the necessary context for rule evaluation.
+* Falco evaluates the rules against the processed events and generates alerts based on the defined security policies.
+
+### Proposed Architecture Overview
+
+![Multi-Threaded Falco Architecture](images/falco-multi-thread-architecture.png)
+
+* The kernel driver (modern eBPF probe) routes events into per-partition ring buffers based on TGID. The routing logic executes in kernel space (within the eBPF program), where each event's TGID is hashed and used to select the target ring buffer. Only the modern eBPF probe is supported, as it relies on [BPF_MAP_TYPE_RINGBUF](https://docs.ebpf.io/linux/map-type/BPF_MAP_TYPE_RINGBUF/) which does not have a per-CPU design as opposed to the `BPF_MAP_TYPE_PERF_EVENT_ARRAY` used by the legacy eBPF probe.
+* Each ring buffer is associated with an event loop worker thread that processes events from its assigned ring buffer.
+* The `libsinsp` state (e.g., the thread state) is maintained in a shared data structure, allowing all workers to access data pushed by other workers. This is crucial for handling events like clone() that rely on data written by other partitions. This requires designing lightweight synchronization mechanisms to ensure efficient access to shared state without introducing significant contention. A dedicated proposal document will address the design of the shared state and synchronization mechanisms, and data consistency.
+* Falco's rule evaluation is performed in parallel by multiple worker threads, each evaluating rules against the events they process. Current Falco plugins are not supposed to be thread-safe. A dedicated proposal document will address the design of a thread-safe plugin architecture.
+* **Output handling** is already designed for multi-threaded access. The `falco_outputs` class implements a thread-safe, queue-based architecture using Intel TBB's `concurrent_bounded_queue`, which is specifically designed for multi-producer, single-consumer scenarios. Multiple worker threads can concurrently call `handle_event()` to enqueue alert messages using the thread-safe `try_push()` operation. A dedicated output worker thread consumes messages from the queue using `pop()` and sends them to all configured outputs (stdout, file, syslog, gRPC, HTTP, etc.). This design is already proven in production, as Falco's multi-source support (where different event sources run in separate threads) already uses this same queue concurrently. The existing implementation requires no changes to support multi-threaded event processing. Note that while outputs are processed in order within the queue, alerts from different worker threads may be interleaved, meaning strict temporal ordering of alerts across different processes is not guaranteed. This is acceptable for security monitoring use cases where the primary concern is detecting and reporting security events rather than maintaining precise event ordering.
+
+### Work Partitioning Strategies
+
+A crucial and challenging design aspect is partitioning the work to achieve a good trade-off among the following properties:
+
+1. **Even load balancing** between threads
+2. **Low contention** on shared data (or no shared data)
+3. **Avoiding temporal inconsistencies and causality violations** (e.g., processing a file-opening event before the related process-forking event)
+
+The first two properties are primarily focused on performance, while the third is essential for the correctness of the solution. These aspects are intrinsically linked.
+
+Based on the analysis below, **Static Partitioning by TGID** is the proposed approach for the initial implementation.
+
+#### Static Partitioning by TGID (Thread Group ID / Process ID)
+
+Events are routed based on the TGID in kernel space (within the eBPF program) to a ring buffer dedicated to a specific partition. The routing logic executes at the point where events are captured, before they are written to any ring buffer. This partition is then consumed by a dedicated worker thread in userspace. The routing in the eBPF program can be accomplished with a simple hash and modulo operation, depending on the desired number of worker threads:
+
+```
+ring_buffer_index = hash(event->tgid) % num_workers
+```
+
+The hash function and number of workers are configured at eBPF program initialization time, allowing the kernel to route events directly to the appropriate ring buffer without userspace intervention.
+
+**Pros:**
+
+* **Reduced need for thread synchronization**: While structures keeping thread group data are shared across all worker threads and require synchronization, TGID partitioning minimizes cross-partition access. For data stored per thread-group (such as file descriptors), TGID partitioning guarantees a single writer (the worker thread assigned to that TGID), resulting in low contention since the data is mostly accessed by the same partition. Synchronization is needed only in two specific cases:
+  1. **Clone/fork events**: When handling clone/fork events, the worker thread needs to access thread information from the parent thread, which may reside in a different partition. This requires synchronization to read the parent's state (e.g., file descriptors, environment variables) that will be inherited by the child.
+  2. **Proc exit events**: When a process exits, reparenting logic may need to access thread information from other partitions to handle child processes that are being reparented to a different thread group.
+* Guarantee of sequential order processing of events related to the same thread group/process, as they are handled by the same worker thread. This limits the chance of temporal inconsistencies.
+
+**Cons:**
+
+* **Load Imbalance / "Hot" Process Vulnerability**: This static partitioning is susceptible to uneven worker load distribution, as a small number of high-activity ("hot") processes can overload the specific worker thread assigned to their TGID, creating a bottleneck.
+* **Cross-Partition Temporal Inconsistency**: Events that require information from a parent thread (e.g., fork/clone events) can still lead to causality issues. If the parent's related event is handled by a different, lagging partition, the required context might be incomplete or arrive out of order. Note that load imbalance amplifies this issue. Missing thread information is easy to detect, but there are also cases where information is present but not up-to-date or ahead of the time the clone event happened.
+
+  **Ancestor information during rule evaluation**: When evaluating rules that require ancestor information, the worker thread may need to access thread data from other partitions. Falco rules commonly check ancestor process attributes using fields that traverse the process hierarchy. Based on actual usage in Falco rules, commonly used ancestor fields include:
+  
+  - `proc.aname` / `proc.aname[N]` - ancestor process name (where N is the generation level: 1=parent, 2=grandparent, 3=great-grandparent, etc., up to at least level 7)
+  - `proc.aexepath[N]` - ancestor executable path (e.g., `proc.aexepath[2]` for grandparent)
+  - `proc.aexe[N]` - ancestor executable (e.g., `proc.aexe[2]` for grandparent)
+  
+  Accessing stale or "ahead" ancestor data (where the ancestor's state may be out of date or from events processed by other partitions with different timestamps) could lead to false positives or false negatives in rule evaluation. We acknowledge this potential issue and plan to assess its impact and determine appropriate mitigations once we have a running prototype.
+
+**Mitigations:**
+
+* **Last-Resort Fetching**: Fetching the thread information from a different channel to resolve the drift (e.g., proc scan, eBPF iterator). This solution is considered as a last resort because it risks slowing down the event processing loop, potentially negating the performance benefits of multi-threading.
+
+* **Context Synchronization**: Wait for the required thread information to become available. This can be decomposed into two orthogonal concerns:
+
+  **How to handle the wait:**
+
+  * **Wait/Sleep (Blocking)**: The worker thread blocks (sleeping or spinning) until the required data becomes available. Simple to implement, but the worker is idle during the wait, reducing throughput.
+  * **Deferring (Non-blocking)**: The event is copied/buffered for later processing; the worker continues with other events from its ring buffer. More complex (requires event copying, a pending queue, and a retry mechanism), but keeps the worker productive.
+
+  **How to detect data readiness:**
+
+  * **Polling**: Periodically check if the required data is available (spin-check for Wait/Sleep, or periodic retry for Deferring). Simple but wastes CPU cycles.
+  * **Signaling**: Partitions proactively notify each other when data is ready. More efficient but requires coordination infrastructure (e.g., condition variables, eventfd, or message queues).
+
+  These combine into four possible approaches:
+
+  | | Polling | Signaling |
+  |---|---------|-----------|
+  | **Wait/Sleep** | Spin-check until ready | Sleep on condition variable, wake on signal |
+  | **Deferring** | Periodically retry deferred events | Process deferred events when signaled |
+
+  **Synchronization point**: A natural synchronization point is the **clone exit parent event**. At this point, the parent process has completed setting up the child's initial state (inherited file descriptors, environment, etc.), making it safe to start processing events for the newly created thread group.
+
+  **Special case — `vfork()` / `CLONE_VFORK`**: When `vfork()` is used, the parent thread is blocked until the child calls `exec()` or exits, delaying the clone exit parent event. An alternative synchronization point may be needed (e.g., adding back clone enter parent).
+
+### Other Considered Approaches
+
+#### Static Partitioning by TID (Thread ID)
+
+Similar to the previous approach, but events are routed by TID instead of TGID.
+
+**Pros:**
+
+* Guarantee of sequential order processing of events related to the same thread, as they are handled by the same worker thread. This limits the chance of temporal inconsistencies.
+* Good enough load balancing between partitions.
+
+**Cons:**
+
+* **Cross-Partition Temporal Inconsistency**: This approach can lead to temporal inconsistencies when accessing/writing information from/to other processes or from the Thread Group Leader (e.g., environment, file descriptor information is stored in the thread group leader).
+
+#### Static Partitioning by CPU Core
+
+This approach routes events based on the CPU core where the event was captured. Each CPU core has its own ring buffer (per-CPU buffers), and multiple CPU buffers are assigned to the same partition. Each partition is consumed by a dedicated worker thread that reads from all the per-CPU buffers assigned to it. The number of partitions does not necessarily match the number of CPU cores—a single partition can read from multiple per-CPU buffers, allowing flexibility in choosing the number of worker threads independently from the number of CPU cores. This leverages the existing per-CPU ring buffer infrastructure used by the kernel module (kmod) and legacy eBPF probe, where events are written to per-CPU buffers that are then grouped into partitions consumed by worker threads.
+
+**Pros:**
+
+* **Natural Load Distribution**: Events are naturally distributed across CPUs based on where processes execute, providing inherent load balancing that reflects actual system activity.
+* **No Routing Logic Required**: Uses the existing per-CPU ring buffer design, eliminating the need for custom routing logic in kernel or userspace. CPU cores are simply mapped to partitions (e.g., via modulo operation: `partition = cpu_id % num_workers`), and each worker thread reads from all per-CPU buffers assigned to its partition.
+* **Low Synchronization Overhead**: Events from per-CPU buffers assigned to the same partition are processed sequentially by the same worker thread, reducing cross-thread synchronization needs.
+* **Flexible Partitioning**: The number of partitions (and thus worker threads) can be chosen independently from the number of CPU cores, allowing optimization based on workload characteristics rather than hardware topology.
+
+**Cons:**
+
+* **Cross-CPU Temporal Inconsistency**: Events from the same process or thread group can be processed by different worker threads if the process migrates between CPUs, leading to potential temporal inconsistencies and causality violations. This is particularly problematic for multi-threaded applications that may execute on different CPUs.
+* **Process Migration Effects**: CPU migration can cause events from the same process to be processed out of order, as events captured on different CPUs are handled by different worker threads.
+* **Load Imbalance with CPU Grouping**: When multiple per-CPU buffers are assigned to the same partition, the worker thread must process events from all assigned buffers. If the activity levels across these CPUs are uneven, the worker thread may experience load imbalance, with some partitions handling more active CPUs than others. The worker thread must also coordinate reading from multiple buffers, potentially using techniques similar to the current `O(n_cpus)` scan to maintain event ordering.
+* **Modern eBPF Probe Limitation**: The modern eBPF probe uses `BPF_MAP_TYPE_RINGBUF`, which does not have a per-CPU design. This approach would only be viable with the kernel module (kmod) or legacy eBPF probe that use `BPF_MAP_TYPE_PERF_EVENT_ARRAY` with per-CPU buffers.
+
+#### Functional Partitioning (Pipelining)
+
+Instead of partitioning the data, this approach partitions the work by splitting processing into phases:
+
+1. **Parsing**: Runs in a single thread, the state is updated in this phase.
+2. **Rules evaluation**: Runs in a thread chosen from a worker thread pool, the state is accessed but not modified.
+
+**Pros:**
+
+* The state handling remains single-threaded, avoiding any synchronization issue on the write side.
+* The load balancing of the Rules evaluation phase is good as it does not require any form of stickiness. Every worker can take whatever event, and a simple round-robin policy can be applied.
+
+**Cons:**
+
+* The "Parsing" stage is likely to become the bottleneck; a single thread here limits total throughput regardless of how many cores you have.
+* As we are parallelizing parsing and rules evaluation phases, we need an MVCC (multi-version concurrency control) technique to maintain multiple levels of state to use the state at the right point in time during rules evaluation.
+* Processing multiple events in parallel involves changes at the driver and libscap level. At the moment we are processing one event at a time from the driver memory without copying. To be able to process multiple events in parallel, we need to adapt the ring-buffer to make sure that `next()` does not consume the event. We would also need some flow control (e.g., backpressure) to avoid processing too many events in parallel. This problem would arise only if the rules evaluation phase is slower than the parsing phase.
+
+#### Comparison Summary
+
+| Approach | Load Balancing | Contention | Temporal Consistency |
+|----------|----------------|------------|----------------------|
+| TGID | Moderate (hot process risk) | Low | Good (within process) |
+| TID | Good | Higher | Partial (thread-level only) |
+| CPU Core | Good | Low | Poor (process migration issues) |
+| Pipelining | Good (rules evaluation phase) | Low (writes) | Requires MVCC |
+
+#### Rationale for TGID Partitioning
+
+TGID partitioning was chosen because it offers the best balance between synchronization complexity and correctness guarantees. TID partitioning increases cross-partition access for thread group leader data (e.g., file descriptor table, working directory, environment variables), increasing the coordination cost. Per-CPU partitioning, while leveraging existing infrastructure, suffers from process migration issues that can cause significant temporal inconsistencies when processes move between CPUs. Functional partitioning, while elegant in its separation of concerns, introduces a single-threaded bottleneck in the parsing phase that limits scalability regardless of available cores, and requires complex MVCC mechanisms for data consistency and mechanisms for handling multiple events in parallel.
+
+### Risks and Mitigations
+
+- **Increased Complexity**: Multi-threading introduces complexity in terms of synchronization and state management. Mitigation: Careful design of shared state and synchronization mechanisms, along with thorough testing.
+- **Synchronization Overhead vs Performance Gains**: The overhead of synchronization might negate the performance benefits of multi-threading. Mitigation: Use lightweight synchronization techniques and minimize shared state access.
+- **Synchronization Overhead vs Data Consistency**: In order to keep the synchronization overhead low with the shared state, we might need to relax some data consistency guarantees. Mitigation: Analyze the trade-offs and ensure that any relaxed guarantees do not compromise security.

+# Legacy eBPF probe, gVisor libscap engine and gRPC output deprecations
+
+## Summary
+
+This proposal aims to formalize motivations and procedures for deprecating the legacy eBPF probe, the gRPC output and
+the gVisor libscap engine.
+
+One of the key objectives of Falco is to maintain a seamless user experience, regardless of the system call event source
+actually used. This objective imposes strong requirements among all drivers and engines acting as system call source
+(i.e.: gVisor libscap engine), feature parity, among each other, above all. Feature parity raises challenges from both
+technical and maintainability perspectives, and these challenges are not justified if the driver/engine is no/little
+used. For these reasons, this document aims for raising consensus regarding the legacy eBPF probe and gRPC output
+deprecation.
+
+Similar arguments could be raised in favor of the gRPC output deprecation: this output requires dependency on the
+gRPC framework, that introduces a non-negligible build time overhead and maintainability burden (especially in a C++
+codebase), not justified by the little usage of the output.
+
+Upcoming evidences of non-negligible use of the gVisor engine and the gRPC output could be addressed by providing a
+separate source plugin in case of gVisor, and a Falco Sidekick output as a replacement of the gRPC output.
+

+
+The legacy eBPF probe strives to provide a little more coverage than the modern eBPF one. This increased coverage comes
+at cost of flexibility and maintainability. Indeed:
+1. it cannot leverage CORE eBPF features - as a result, falcosecurity must maintain a great number of officially
+supported eBPF objects, each one built for a specific officially-supported kernel flavor; this increases the
+maintainability burden and makes the system less flexible to kernel configurations/structures changes
+2. old kernel versions support is difficult to retain - the verifier imposes huge limitations on old kernel versions,
+and any tiny change easily result in the verifier rejecting the code
+3. it is difficult to keep it up to date with other drivers - some desired features cannot be implemented in any way
+using eBPF on old kernel flavors, due to lack of eBPF helpers/program types or verifier limitations (e.g.: there is no
+way of implementing a synchronous data harvesting mechanism like the one provided by BPF iterators). As falcosecurity
+strives for feature parity among drivers, this imposes a big limitation on the other drivers. Please notice that:
+   1. the kernel module is unconstrained on the nature of feature it can support
+   2. the modern eBPF probe can easily rely on CORE features to probe for kernel features and use them if available
+
+Besides the above, the legacy eBPF probe provides support for a range of versions that is entirely contained by the
+kernel module supported range. Additionally, different distro kernel flavors already back-port features required by the
+modern eBPF, enabling its usage on kernel older than `5.8`.
+
+The above considerations, together with the evidence of its little usage, make the legacy eBPF probe a good candidate
+for deprecation.
+
+### gVisor libscap engine deprecation
+
+gVisor libscap engine implements a system call event source by leveraging events coming from gVisor itself through gRPC.
+
+There is evidence that this engine is little used. Moreover, gVisor doesn't provide all information required to build
+all supported event types, indeed resulting in a system call source not completely equivalent to the ones provided by
+drivers. Finally, it requires `falcosecurity/libs` being dependent on protobuf, this latter introducing a non-negligible
+build time overhead and maintainability burden.
+
+Deprecating it would allow to streamline system call event sources alignment, maintainability, and reduce build time for
+both `falcosecurity/falco` and `falcosecurity/libs`.
+
+### gRPC output deprecation
+
+The gRPC output provides a mechanism through which a gRPC client can subscribe to the Falco alerts stream. This output
+leverages a gRPC server embedded into Falco.
+
+As for the legacy eBPF probe and the gVisor libscap engine, there is evidence that this output is little used. Also,
+similarly to the gVisor libscap engine, this requires Falco being dependent on the protobuf, and additionally, on the
+entire C++ gRPC framework. Finally, the little amount of data that is sent through the gRPC stream, and the
+communication model (only involving a one-way communication from the server to the client) doesn't justify the need of
+using gRPC.
+
+Deprecating it would allow to reduce the build system, streamline maintainability, and reduce build time for
+`falcosecurity/falco`.
+
+## Goals
+
+* Deprecate the legacy eBPF probe, the gVisor libscap engine, and the gRPC output
+* Detail a plan to follow during the deprecation period, before completely remove any of the aforementioned components
+
+## Non-goals
+
+* Implement a gVisor source plugin as gVisor libscap engine alternative
+* Implement the gRPC output as Falco Sidekick output
+* Detail a plan to follow after taking the decision to completely remove any of the aforementioned components
+
+## The plan
+
+This section aims to detail the plan to follow contextually and after the deprecation mark, but before taking any
+definitive removal decision about the legacy eBPF probe, the gVisor libscap engine, and the gRPC output (collectively
+referred to hereinafter as "the components" or simply "components").
+
+The deprecation of these components introduces user-facing changes that must be addressed as prescribed by the current
+deprecation policy for "non-backward compatible user-facing changes" (see
+[20231220-features-adoption-and-deprecation.md#deprecation-policy](./20231220-features-adoption-and-deprecation.md#deprecation-policy)).
+
+All components are stable, and considering that deprecations will first be enforced in the stable Falco version `0.43.0`
+(ante `1.0.0`), the minimum deprecation period length is 1 release: this means that components cannot be removed before
+Falco `0.44.0`.
+
+At high level, the action plan is to inform users, during the deprecation period, about the deprecation: this is
+achieved by emitting a deprecation notice if the user try to leverage any of the feature exposed by any component, and
+by updating the website in any of the relevant areas.
+
+During the deprecation period, but before taking decision to remove the components, projects belonging to the
+`falcosecurity` organization will be updated to not use/rely on any of these. Specifically:
+- on `falcosecurity/libs`, any CI job building and testing the legacy eBPF probe will be removed
+- on `falcosecurity/kernel-testing`, playbooks will not build and test the legacy eBPF probe anymore
+- on `falcosecurity/event-generator`, the internal gRPC alert retriever will be replaced with an HTTP alert retriever,
+leveraging the existing HTTP output.
+
+## The non-plan
+
+This proposal does not address any design or implementation aspect of the gVisor engine and gRPC output replacement, nor
+formalizes in any way the conditions under which a replacement should be delivered. Upcoming evidences of non-negligible
+use of the gVisor engine and the gRPC output may be addressed by providing a separate source plugin in case of gVisor,
+and a Falco Sidekick output as a replacement of the gRPC output, but these latter possibilities should be intended as
+suggestions, and will not constraint in any way any related future choice.
+
+Finally, this proposal doesn't detail any aspect of the eventual removal.
