 * [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
 
-* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.

Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containers which could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.

The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.

We route all Falco events to our control systems, both monitoring and logging. Being able to deeply analyse alerts, we can understand what is running on our Kubernetes clusters and check against security policies, specifically defined for each workload.

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.

+## Code of Conduct
+
+Falco has a
+[Code of Conduct](CODE_OF_CONDUCT.md)
+to which all contributors must adhere, please read it before interacting with the repository or the community in any way.
+
+## Issues
+
+Issues are the heartbeat ❤️ of the Falco project, there are mainly three kinds of issues you can open:
+
+- Bug report: you believe you found a problem in Falco and you want to discuss and get it fixed,
+creating an issue with the **bug report template** is the best way to do so.
+- Enhancement: any kind of new feature need to be discussed in this kind of issue, do you want a new rule or a new feature? This is the kind of issue you want to open. Be very good at explaining your intent, it's always important that others can understand what you mean in order to discuss, be open and collaborative in letting others help you getting this done!
+- Failing tests: you noticed a flaky test or a problem with a build? This is the kind of issue to triage that!
+
+The best way to get **involved** in the project is through issues, you can help in many ways:
+
+- Issues triaging: participating in the discussion and adding details to open issues is always a good thing,
+sometimes issues need to be verified, you could be the one writing a test case to fix a bug!
+- Helping to resolve the issue: you can help in getting it fixed in many ways, more often by opening a pull request.
+
+### Triage issues
+
+We need help in categorizing issues. Thus any help is welcome!
+
+When you triage an issue, you:
+
+* assess whether it has merit or not
+
+* quickly close it by correctly answering a question
+
+* point the reporter to a resource or documentation answering the issue
+
+* tag it via labels, projects, or milestones
+
+* take ownership submitting a PR for it, in case you want 😇
+
+#### More about labels
+
+These guidelines are not set in stone and are subject to change.
+
+Anyway a `kind/*` label for any issue is mandatory.
+
+This is the current [label set](https://github.com/falcosecurity/falco/labels) we have.
+
+You can use commands - eg., `/label <some-label>` to add (or remove) labels or manually do it.
+
+The commands available are the following ones:
+
+```
+/[remove-](area|kind|priority|triage|label)
+```
+
+Some examples:
+
+* `/area rules`
+* `/remove-area rules`
+* `/kind kernel-module`
+* `/label good-first-issue`
+* `/triage duplicate`
+* `/triage unresolved`
+* `/triage not-reproducible`
+* `/triage support`
+* ...
+
+### Slack
+
+Other discussion, and **support requests** should go through the `#falco` channel in the Kubernetes slack, please join [here](https://slack.k8s.io/).
+
+## Pull Requests
+
+Thanks for taking time to make a [pull request](https://help.github.com/articles/about-pull-requests) (hereafter PR).
+
+In the PR body, feel free to add an area label if appropriate by typing `/area <AREA>`, PRs will also
+need a kind, make sure to specify the appropriate one by typing `/kind <KIND>`.
+
+The list of labels is [here](https://github.com/falcosecurity/falco/labels).
+
+Also feel free to suggest a reviewer with `/cc @theirname`, or to assign an assignee using `/assign @nickname`.
+
+Once your reviewer is happy, they will say `/lgtm` which will apply the
+`lgtm` label, and will apply the `approved` label if they are an
+[owner](/OWNERS).
+
+Your PR will be automatically merged once it has the `lgtm` and `approved`
+labels, does not have any `do-not-merge/*` labels, and all status checks (eg., rebase, tests, DCO) are positive.
+
+### Commit convention
+
+As commit convention, we adopt [Conventional Commits v1.0.0](https://www.conventionalcommits.org/en/v1.0.0/), we have an history
+of commits that do not adopt the convention but any new commit must follow it to be eligible for merge.
+
+#### Rule type
+
+Besides the classic types, we adopt a type for rules, `rule(<scope>):`.
+Example:
+
+```
+rule(Write below monitored dir): make sure monitored dirs are monitored.
+```
+
+Each rule change must be on its own commit, if a change to a macro is done while changing a rule they can go together but only one rule per commit must happen.
+
+If you are changing only a macro, the commit will look like this:
+
+```
+rule(macro user_known_write_monitored_dir_conditions): make sure conditions are great
+```
+
+## Coding Guidelines
+
+### C++
+
+* File `userspace/engine/banned.h` defines some functions as invalid tokens. These functions are not allowed to be used in the codebase. Whenever creating a new cpp file, include the `"banned.h"` headers. This ensures that the banned functions are not compiled.
+
+  A complete list of banned functions can be found [here](./userspace/engine/banned.h).
+
+## Developer Certificate Of Origin
+
+The [Developer Certificate of Origin (DCO)](https://developercertificate.org/) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project.
+
+Contributors to the Falco project sign-off that they adhere to these requirements by adding a `Signed-off-by` line to commit messages.
+
+```
+This is my commit message
+
+Signed-off-by: John Poiana <jpoiana@falco.org>
+```
+
+Git even has a `-s` command line option to append this automatically to your commit message:
+
+```
+$ git commit -s -m 'This is my commit message'
+```

+# Process for becoming a maintainer
+
+* Express interest to the existing maintainers that you or your organization is interested in becoming a
+  maintainer. Becoming a maintainer generally means that you are going to be spending substantial
+  time (>25%) on Falco for the foreseeable future. You should have domain expertise and be extremely
+  proficient in C++. Ultimately your goal is to become a maintainer that will represent your
+  organization.
+* We will expect you to start contributing increasingly complicated PRs, under the guidance
+  of the existing maintainers.
+* We may ask you to do some PRs from our backlog.
+* As you gain experience with the code base and our standards, we will ask you to do code reviews
+  for incoming PRs (i.e., all maintainers are expected to shoulder a proportional share of
+  community reviews).
+* After a period of approximately 2-3 months of working together and making sure we see eye to eye,
+  the existing maintainers will confer and decide whether to grant maintainer status or not.
+  We make no guarantees on the length of time this will take, but 2-3 months is the approximate
+  goal.
+
+## Maintainer responsibilities
+
+* Monitor Slack (delayed response is perfectly acceptable).
+* Triage GitHub issues and perform pull request reviews for other maintainers and the community.
+* During GitHub issue triage, apply all applicable [labels](https://github.com/falcosecurity/falco/labels)
+  to each new issue. Labels are extremely useful for future issue follow up. Which labels to apply
+  is somewhat subjective so just use your best judgment.
+* Make sure that ongoing PRs are moving forward at the right pace or closing them.
+* Participate when called upon in the security releases. Note that although this should be a rare
+  occurrence, if a serious vulnerability is found, the process may take up to several full days of
+  work to implement. This reality should be taken into account when discussing time commitment
+  obligations with employers.
+* In general continue to be willing to spend at least 25% of ones time working on Falco (~1.25
+  business days per week).
+
+## When does a maintainer lose maintainer status
+
+If a maintainer is no longer interested or cannot perform the maintainer duties listed above, they
+should volunteer to be moved to emeritus status. In extreme cases this can also occur by a vote of
+the maintainers per the voting process below.
+
+# Conflict resolution and voting
+
+In general, we prefer that technical issues and maintainer membership are amicably worked out
+between the persons involved. If a dispute cannot be decided independently, the maintainers can be
+called in to decide an issue. If the maintainers themselves cannot decide an issue, the issue will
+be resolved by voting. The voting process is a simple majority in which each senior maintainer
+receives two votes and each normal maintainer receives one vote.
+
+# Adding new projects to the falcosecurity GitHub organization
+
+New projects will be added to the falcosecurity organization via GitHub issue discussion in one of the
+existing projects in the organization. Once sufficient discussion has taken place (~3-5 business
+days but depending on the volume of conversation), the maintainers of *the project where the issue
+was opened* (since different projects in the organization may have different maintainers) will
+decide whether the new project should be added. See the section above on voting if the maintainers
+cannot easily decide.

-The Falco Project, originally created by [Sysdig](https://sysdig.com), is an incubating [CNCF](https://cncf.io) open source cloud native runtime security tool.
-Falco makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack.
-Falco has a rich set of security rules specifically built for Kubernetes, Linux, and cloud-native.
-If a rule is violated in a system, Falco will send an alert notifying the user of the violation and its severity.
+Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel. Falco then enriches this data with other input streams such as container runtime metrics, and Kubernetes metrics. Falco lets you continuously monitor and detect container, application, host, and network activity—all in one place—from one source of data, with one set of rules.
 
-### Installing Falco
+Falco is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox level project. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details read the [Falco CNCF project proposal](https://github.com/cncf/toc/tree/master/proposals/falco.adoc).
 
-If you would like to run Falco in **production** please adhere to the [official installation guide](https://falco.org/docs/getting-started/installation/).
+#### What kind of behaviors can Falco detect?
 
-##### Kubernetes
+Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, Falco can easily detect incidents including but not limited to:

-### Developing
-
-Falco is designed to be extensible such that it can be built into cloud-native applications and infrastructure.
-
-Falco has a [gRPC](https://falco.org/docs/grpc/) endpoint and an API defined in [protobuf](https://github.com/falcosecurity/falco/blob/master/userspace/falco/outputs.proto).
-The Falco Project supports various SDKs for this endpoint.

-### What can Falco detect?
-
-Falco can detect and alert on any behavior that involves making Linux system calls.
-Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process.
-For example, Falco can easily detect incidents including but not limited to:
-
-- A shell is running inside a container or pod in Kubernetes.
+- A shell is running inside a container.
 - A container is running in privileged mode, or is mounting a sensitive path, such as `/proc`, from the host.
 - A server process is spawning a child process of an unexpected type.
 - Unexpected read of a sensitive file, such as `/etc/shadow`.
 - A non-device file is written to `/dev`.
 - A standard system binary, such as `ls`, is making an outbound network connection.
-- A privileged pod is started in a Kubernetes cluster.

+
+#### How do you compare Falco with other security tools?
+
+One of the questions we often get when we talk about Falco is “How does Falco differ from other Linux security tools such as SELinux, AppArmor, Auditd, etc.?”. We wrote a [blog post](https://sysdig.com/blog/selinux-seccomp-falco-technical-discussion/) comparing Falco with other tools.

 ## Pre-Release Checklist
 
-Before cutting a release we need to do some homework in the Falco repository. This should take 5 minutes using the GitHub UI.
-
 ### 1. Release notes
-- Find the LAST release (-1) and use `YYYY-MM-DD` as the day before of the [latest release](https://github.com/falcosecurity/falco/releases)
+- Let `YYYY-MM-DD` the day before of the [latest release](https://github.com/falcosecurity/falco/releases)
 - Check the release note block of every PR matching the `is:pr is:merged closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+closed%3A%3EYYYY-MM-DD)
     - Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/falco/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
     - If the PR has no milestone, assign it to the milestone currently undergoing release
-- Check issues without a milestone (using [is:pr is:merged no:milestone closed:>YYYY-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) filter) and add them to the milestone currently undergoing release
-- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filters](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, fix them
+- Check issues without a milestone (using [is:pr is:merged no:milestone closed:>YYYT-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-MM-DD) filter) and add them to the milestone currently undergoing release

 ### 3. Release PR
 
 - Double-check if any hard-coded version number is present in the code, it should be not present anywhere:
     - If any, manually correct it then open an issue to automate version number bumping later
-    - Versions table in the `README.md` updates itself automatically
-- Generate the change log https://github.com/leodido/rn2md:
-    - If you review timeout errors with `rn2md` try to generate an GitHub Oauth access token and use `-t`
-- Add the latest changes on top the previous `CHANGELOG.md`

-### 3. Update the meeting notes
-
-For each release we archive the meeting notes in git for historical purposes.
-
- - The notes from the Falco meetings can be [found here](https://hackmd.io/6sEAlInlSaGnLz2FnFz21A).
-    - Note: There may be other notes from working groups that can optionally be added as well as needed.
- - Add the entire content of the document to a new file in [github.com/falcosecurity/community/tree/master/meeting-notes](https://github.com/falcosecurity/community/tree/master/meeting-notes) as a new file labeled `release-x.y.z.md`
- - Open up a pull request with the new change.

-    # However, they forgot to push the released makefiles

-    # This is needed because many distros do not ship the right

-# Falco Artifacts Storage
-
-This document reflects the way we store the Falco artifacts.
-
-## Terms & Definitions
-
-- [Falco artifacts](./20200506-artifacts-scope-part-1.md)
-- Bintray: artifacts distribution platform
-
-## Packages
-
-The Falco packages are **automatically** built and sent to [bintray](https://bintray.com/falcosecurity) in the following cases:
-
-- a pull request gets merged into the master branch (**Falco development releases**)
-- a new Falco release (git tag) happens on the master branch (**Falco stable releases**)
-
-The only prerequisite is that the specific Falco source code builds successfully and that the tests pass.
-
-As per [Falco Artifacts Scope (#1)](./20200506-artifacts-scope-part-1.md) proposal we provide three kind of Falco packages:
-
-- DEB
-- RPM
-- Tarball
-
-Thus, we have three repositories for the Falco stable releases:
-
-- https://bintray.com/falcosecurity/deb
-- https://bintray.com/falcosecurity/rpm
-- https://bintray.com/falcosecurity/bin
-
-And three repositories for the Falco development releases:
-
-- https://bintray.com/falcosecurity/deb-dev
-- https://bintray.com/falcosecurity/rpm-dev
-- https://bintray.com/falcosecurity/bin-dev
-
-## Drivers
-
-The process of publishing a set of prebuilt Falco drivers is implemented by the **Drivers Build Grid (DBG)** in the [test-infra](https://github.com/falcosecurity/test-infra/tree/master/driverkit) repository (`driverkit` directory).
-
-This process is driven by the configuration files (YAML) present in the `driverkit/config` directory in the [test-infra](https://github.com/falcosecurity/test-infra/tree/master/driverkit) repository.
-
-Each of these files represents a prebuilt driver (eventually two: kernel module and eBPF probe, when possible) that will be published on [bintray](https://bintray.com/falcosecurity) if it builds correctly.
-
-Every time the `driverkit/config` directory on the master branch has some changes from the previous commit the CI system, which you can find defined in the [.circleci/config.yml](https://github.com/falcosecurity/test-infra/blob/master/.circleci/config.yml) file, takes care of building and publishing all the drivers.
-
-The driver versions we ship prebuilt drivers for are:
-
-- the driver version associated with the last Falco stable version ([see here](https://github.com/falcosecurity/falco/blob/c4b7f17271d1a4ca533b2e672ecaaea5289ccdc5/cmake/modules/sysdig.cmake#L29))
-- the driver version associated with the penultimate Falco stable version
-
-The prebuilt drivers get published into [this](https://bintray.com/falcosecurity/driver) generic artifacts repository.
-
-You can also visualize the full list of prebuilt drivers by driver version visiting this [URL](https://dl.bintray.com/falcosecurity/driver).
-
-### Notice
-
-The generation of new prebuilt drivers takes usually place with a frequency of 1-2 weeks, on a **best-effort** basis.
-
-Thus, it can happen the list of available prebuilt drivers does not yet contain the driver version currently on Falco master.
-
-Nevertheless, this process is an open, auditable, and transparent one.
-
-So, by sending a pull-request towards [test-infra](https://github.com/falcosecurity/test-infra) repository containing the configuration YAML files you can help the Falco community stay on track.
-
-Some pull-requests you can look at to create your own are:
-
-- https://github.com/falcosecurity/test-infra/pull/165
-- https://github.com/falcosecurity/test-infra/pull/163
-- https://github.com/falcosecurity/test-infra/pull/162
-
-While, the documentation of the YAML configuration files can be found [here](https://github.com/falcosecurity/driverkit/blob/master/README.md).
-
-## Container images
-
-As per Falco packages, also the Falco official container images are **automatically** published to the [dockerhub](https://hub.docker.com/r/falcosecurity/falco).
-
-These images are built and published in two cases:
-
-- a pull request gets merged into the master branch (**Falco development releases**)
-- a new Falco release (git tag) happens (**Falco stable releases**)
-
-For a detailed explanation of the container images we build and ship look at the following [documentation](https://github.com/falcosecurity/falco/blob/master/docker/README.md).

-# Proposal for First Class Structured Exceptions in Falco Rules
-
-## Summary
-
-## Motivation
-
-Almost all Falco Rules have cases where the behavior detected by the
-rule should be allowed. For example, The rule Write Below Binary Dir
-has exceptions for specific programs that are known to write below
-these directories as a part of software installation/management:
-
-```yaml
-- rule: Write below binary dir
-  desc: an attempt to write to any file below a set of binary directories
-  condition: >
-    bin_dir and evt.dir = < and open_write
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not python_running_get_pip
-    and not python_running_ms_oms
-    and not user_known_write_below_binary_dir_activities
-...
-```
-In most cases, these exceptions are expressed as concatenations to the original rule's condition. For example, looking at the macro package_mgmt_procs:
-
-```yaml
-- macro: package_mgmt_procs
-  condition: proc.name in (package_mgmt_binaries)
-```
-
-The result is appending `and not proc.name in (package_mgmt_binaries)` to the condition of the rule.
-
-A more extreme case of this is the write_below_etc macro used by Write below etc rule. It has tens of exceptions:
-
-```
-...
-    and not sed_temporary_file
-    and not exe_running_docker_save
-    and not ansible_running_python
-    and not python_running_denyhosts
-    and not fluentd_writing_conf_files
-    and not user_known_write_etc_conditions
-    and not run_by_centrify
-    and not run_by_adclient
-    and not qualys_writing_conf_files
-    and not git_writing_nssdb
-...
-```
-
-The exceptions all generally follow the same structure--naming a program and a directory prefix below /etc where that program is allowed to write files.
-
-### Using Appends/Overwrites to Customize Rules
-
-An important way to customize rules and macros is to use `append: true` to add to them, or `append: false` to define a new rule/macro, overwriting the original rule/macro. Here's an example from Update Package Repository:
-
-```yaml
-- list: package_mgmt_binaries
-  items: [rpm_binaries, deb_binaries, update-alternat, gem, pip, pip3, sane-utils.post, alternatives, chef-client, apk, snapd]
-
-- macro: package_mgmt_procs
-  condition: proc.name in (package_mgmt_binaries)
-
-- macro: user_known_update_package_registry
-  condition: (never_true)
-
-- rule: Update Package Repository
-  desc: Detect package repositories get updated
-  condition: >
-    ((open_write and access_repositories) or (modify and modify_repositories))
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not user_known_update_package_registry
-```
-
-If someone wanted to add additional exceptions to this rule, they could add the following to the user_rules file:
-
-```yaml
-- list: package_mgmt_binaries
-  items: [puppet]
-  append: true
-
-- macro: package_mgmt_procs
-  condition: and not proc.pname=chef
-  append: true
-
-- macro: user_known_update_package_registry
-  condition: (proc.name in (npm))
-  append: false
-```
-
-This adds an 3 different exceptions:
-* an additional binary to package_mgmt_binaries (because append is true),
-* adds to package_mgmt_procs, adding an exception for programs spawned by chef (because append is true)
-* overrides the macro user_known_update_package_registry to add an exception for npm (because append is false).
-
-### Problems with Appends/Overrides to Define Exceptions
-
-Although the concepts of macros and lists in condition fields, combined with appending to lists/conditions in macros/rules, is very general purpose, it can be unwieldy:
-
-* Appending to conditions can result in incorrect behavior, unless the original condition has its logical operators set up properly with parentheses. For example:
-
-```yaml
-rule: my_rule
-condition: (evt.type=open and (fd.name=/tmp/foo or fd.name=/tmp/bar))
-
-rule: my_rule
-condition: or fd.name=/tmp/baz
-append: true
-```
-
-Results in unintended behavior. It will match any fd related event where the name is /tmp/baz, when the intent was probably to add /tmp/baz as an additional opened file.
-
-* A good convention many rules use is to have a clause "and not user_known_xxxx" built into the condition field. However, it's not in all rules and its use is a bit haphazard.
-
-* Appends and overrides can get confusing if you try to apply them multiple times. For example:
-
-```yaml
-macro: allowed_files
-condition: fd.name=/tmp/foo
-
-...
-
-macro: allowed_files
-condition: and fd.name=/tmp/bar
-append: true
-```
-
-If someone wanted to override the original behavior of allowed_files, they would have to use `append: false` in a third definition of allowed_files, but this would result in losing the append: true override.
-
-## Solution: Exceptions as first class objects
-
-To address some of these problems, we will add the notion of Exceptions as top level objects alongside Rules, Macros, and Lists. A rule that supports exceptions must define a new key `exceptions` in the rule. The exceptions key is a list of identifier plus list of tuples of filtercheck fields. Here's an example:
-
-```yaml
-- rule: Write below binary dir
-  desc: an attempt to write to any file below a set of binary directories
-  condition: >
-    bin_dir and evt.dir = < and open_write
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not python_running_get_pip
-    and not python_running_ms_oms
-    and not user_known_write_below_binary_dir_activities
-  exceptions:
-   - name: proc_writer
-     fields: [proc.name, fd.directory]
-   - name: container_writer
-     fields: [container.image.repository, fd.directory]
-     comps: [=, startswith]
-   - name: proc_filenames
-     fields: [proc.name, fd.name]
-     comps: [=, in]
-   - name: filenames
-     fields: fd.filename
-     comps: in
-```
-
-This rule defines four kinds of exceptions:
-  * proc_writer: uses a combination of proc.name and fd.directory
-  * container_writer: uses a combination of container.image.repository and fd.directory
-  * proc_filenames: uses a combination of process and list of filenames.
-  * filenames: uses a list of filenames
-
-The specific strings "proc_writer"/"container_writer"/"proc_filenames"/"filenames" are arbitrary strings and don't have a special meaning to the rules file parser. They're only used to link together the list of field names with the list of field values that exist in the exception object.
-
-proc_writer does not have any comps property, so the fields are directly compared to values using the = operator. container_writer does have a comps property, so each field will be compared to the corresponding exception items using the corresponding comparison operator.
-
-proc_filenames uses the in comparison operator, so the corresponding values entry should be a list of filenames.
-
-filenames differs from the others in that it names a single field and single comp operator. This changes how the exception condition snippet is constructed (see below).
-
-Notice that exceptions are defined as a part of the rule. This is important because the author of the rule defines what construes a valid exception to the rule. In this case, an exception can consist of a process and file directory (actor and target), but not a process name only (too broad).
-
-Exception values will most commonly be defined in rules with append: true. Here's an example:
-
-```yaml
-- list: apt_files
-  items: [/bin/ls, /bin/rm]
-
-- rule: Write below binary dir
-  exceptions:
-  - name: proc_writer
-    values:
-    - [apk, /usr/lib/alpine]
-    - [npm, /usr/node/bin]
-  - name: container_writer
-    values:
-    - [docker.io/alpine, /usr/libexec/alpine]
-  - name: proc_filenames
-    values:
-    - [apt, apt_files]
-    - [rpm, [/bin/cp, /bin/pwd]]
-  - name: filenames
-    values: [python, go]
-```
-
-A rule exception applies if for a given event, the fields in a rule.exception match all of the values in some exception.item. For example, if a program `apk` writes to a file below `/usr/lib/alpine`, the rule will not trigger, even if the condition is met.
-
-Notice that an item in a values list can be a list. This allows building exceptions with operators like "in", "pmatch", etc. that work on a list of items. The item can also be a name of an existing list. If not present surrounding parantheses will be added.
-
-Finally, note that the structure of the values property differs between the items where fields is a list of fields (proc_writer/container_writer/proc_filenames) and when it is a single field (procs_only). This changes how the condition snippet is constructed.
-
-### Implementation
-
-For exception items where the fields property is a list of field names, each exception can be thought of as an implicit "and not (field1 cmp1 val1 and field2 cmp2 val2 and...)" appended to the rule's condition. For exception items where the fields property is a single field name, the exception can be thought of as an implict "and not field cmp (val1, val2, ...)". In practice, that's how exceptions will be implemented.
-
-When a rule is parsed, the original condition will be wrapped in an extra layer of parentheses and all exception values will be appended to the condition. For example, using the example above, the resulting condition will be:
-
-```
-(<Write below binary dir condition>) and not (
-    (proc.name = apk and fd.directory = /usr/lib/alpine) or (proc.name = npm and fd.directory = /usr/node/bin) or
-	(container.image.repository = docker.io/alpine and fd.directory startswith /usr/libexec/alpine) or
-	(proc.name=apt and fd.name in (apt_files))) or
-	(fd.filename in (python, go))))
-```
-
-The exceptions are effectively syntatic sugar that allows expressing sets of exceptions in a concise way.
-
-### Advantages
-
-Adding Exception objects as described here has several advantages:
-
-* All rules will implicitly support exceptions. A rule writer doesn't need to define a user_known_xxx macro and add it to the condition.
-* The rule writer has some controls on what defines a valid exception. The rule author knows best what is a good exception, and can define the fields that make up the exception.
-* With this approach, it's much easier to add and manage multiple sets of exceptions from multiple sources. You're just combining lists of tuples of filtercheck field values.
-
-## Backwards compatibility
-
-To take advantage of these new features, users will need to upgrade Falco to a version that supports exception objects and exception keys in rules. For the most part, however, the rules file structure is unchanged.
-
-This approach does not remove the ability to append to exceptions nor the existing use of user_xxx macros to define exceptions to rules. It only provides an additional way to express exceptions. Hopefully, we can migrate existing exceptions to use this approach, but there isn't any plan to make wholesale rules changes as a part of this.
-
-This approach is for the most part backwards compatible with older Falco releases. To implement exceptions, we'll add a preprocessing element to rule parsing. The main Falco engine is unchanged.
-
-However, there are a few changes we'll have to make to Falco rules file parsing:
-
-* Currently, Falco will reject files containing anything other than rule/macro/list top-level objects. As a result, `exception` objects would be rejected. We'll probably want to make a one-time change to Falco to allow arbitrary top level objects.
-* Similarly, Falco will reject rule objects with exception keys. We'll also probably want to change Falco to allow unknown keys inside rule/macro/list/exception objects.

-# Falco Artifacts Cleanup
-
-This document reflects when and how we clean up the Falco artifacts from their storage location.
-
-## Motivation
-
-The [bintray](https://bintray.com/falcosecurity) open-source plan offers 10GB free space for storing artifacts.
-
-They also kindly granted us an additional 5GB of free space.
-
-## Goal
-
-Keep the storage space usage under 15GB by cleaning up the [Falco artifacts](./20200506-artifacts-scope-part-1.md) from the [storage](./20200818-artifacts-storage).
-
-## Status
-
-To be implemented.
-
-## Packages
-
-### Tarballs from Falco master
-
-At the moment of writing this document, this kind of Falco package requires approx. 50MB (maximum detected size) of storage space.
-
-Since, historically, the [bin-dev](https://bintray.com/falcosecurity/bin-dev) repository is the less used one, this document proposes to keep only the last 10 **Falco development releases** it contains.
-
-This means that the [bin-dev](https://bintray.com/falcosecurity/bin-dev) repository will take at maximum 500MB of storage space.
-
-### DEB from Falco master
-
-At the moment of writing this document, this kind of Falco package requires approx. 5.1MB (maximum detected size) of storage space.
-
-Historically, every Falco release is composed by less than 50 merges (upper limit).
-
-So, to theoretically retain all the **Falco development releases** that led to a Falco stable release, this document proposes to keep the last 50 Falco DEB packages.
-
-This means that the [deb-dev](https://bintray.com/falcosecurity/deb-dev) repository will take at maximum 255MB of storage space.
-
-### RPM from Falco master
-
-At the moment of writing this document, this kind of Falco package requires approx. 4.3MB (maximum detected size) of storage space.
-
-For the same exact reasons explained above this document proposes to keep the last 50 Falco RPM packages.
-
-This means that the [rpm-dev](https://bintray.com/falcosecurity/rpm-dev) repository will take at maximum 215MB of storage space.
-
-### Stable releases
-
-This document proposes to retain all the stable releases.
-
-This means that all the Falco packages present in the Falco stable release repositories will be kept.
-
-The [bin](https://bintray.com/falcosecurity/bin) repository contains a Falco tarball package for every release.
-This means it grows in space of ~50MB each month.
-
-The [deb](https://bintray.com/falcosecurity/deb) repository contains a Falco DEB package for every release.
-This means it grows in space of ~5MB each month.
-
-The [rpm](https://bintray.com/falcosecurity/rpm) repository contains a Falco RPM package for every release.
-This means it grows in space of ~4.3MB each month.
-
-### Considerations
-
-Assuming the size of the packages does not surpass the numbers listed in the above sections, the **Falco development releases** will always take less that 1GB of artifacts storage space.
-
-Assuming 12 stable releases at year, at the current size of packages, the **Falco stable releases** will take approx. 720MB of storage space every year.
-
-### Implementation
-
-The Falco CI will have a new CI job - called `cleanup/packages-dev` - responsible for removing the **Falco development releases** depending on the above plan.
-
-This job will be triggered after the `publish/packages-dev` completed successfully.
-
-## Drivers
-
-As explained in the [Artifacts Storage](./20200818-artifacts-storage) proposal, we build the drivers for the **last two driver versions** associated with **latest Falco stable releases**.
-Then, we store those drivers into a [generic bintray repository](https://bintray.com/falcosecurity/driver) from which the installation process automatically downloads them, if suitable.
-
-This document proposes to implement a cleanup mechanism that deletes all the other driver versions available.
-
-At the moment of writing, considering only the last two driver versions (**ae104eb**, **85c8895**) associated with the latest Falco stable releases, we ship ~340 eBPF drivers, each accounting for ~3.1MB of storage space, and 1512 kernel modules (~3.1MB size each, too).
-
-Thus, we obtain an estimate of approx. 2.875GB for **each** driver version.
-
-This document proposes to only store the last two driver versions associates with the latest Falco stable releases. And deleting the other ones.
-
-This way, assuming the number of prebuilt drivers does not skyrocket, we can reasonably estimate the storage space used by prebuilt drivers to be around 6GB.
-
-Notice that, in case a Falco stable release will not depend on a new driver version, this means the last two driver versions will, in this case, cover more than the two Falco stable releases.
-
-### Archivation
-
-Since the process of building drivers is time and resource consuming, this document also proposes to move the driver versions in other storage facilities.
-
-The candidate is an AWS S3 bucket responsible for holding the deleted driver version files.
-
-### Implementation
-
-The [test-infra](https://github.com/falcosecurity/test-infra) CI, specifically its part dedicated to run the **Drivers Build Grid** that runs every time it detects changes into the `driverkit` directory of the [test-infra](https://github.com/falcosecurity/test-infra) repository,
-will have a new job - called `drivers/cleanup` - responsible for removing all the Falco driver versions except the last two.
-
-This job will be triggered after the `drivers/publish` completed successfully on the master branch.

-## Introduction
-
-In the past days, as many people probably noticed, Bintray started rate-limiting our users, effectively preventing them from downloading any kernel module, rpm/deb package or any pre-built dependency we host there.
-
-This does not only interrupt the workflow of our users but also the workflow of the contributors, since without bintray most of our container images and CMake files can’t download the dependencies we mirror.
-
-### What is the cause?
-
-We had a spike in adoption apparently, either a user with many nodes or an increased number of users. We don’t know this detail specifically yet because bintray does not give us very fine-grained statistics on this.
-
-This is the 30-days history:
-
-![A spike on driver downloads the last ten days](20201025-drivers-storage-s3_downloads.png)
-
-As you can see, we can only see that they downloaded the latest kernel module driver version, however we can’t see if:
-
-* It’s a single source or many different users
-
-* What is the kernel/OS they are using
-
-### What do we host on Bintray?
-
-* RPM packages: high traffic but very manageable ~90k downloads a month
-
-* Deb packages:low traffic ~5k downloads a month
-
-* Pre-built image Dependencies: low traffic, will eventually disappear in the future
-
-* Kernel modules: very high traffic, 700k downloads in 10 days, this is what is causing the current problems. They are primarily used by users of our container images.
-
-* eBPF probes: low traffic ~5k downloads a month
-
-### Motivations to go to S3 instead of Bintray for the Drivers
-
-Bintray does an excellent service at building the rpm/deb structures for us, however we also use them for S3-like storage for the drivers. We have ten thousand files hosted there and the combinations are infinite.
-
-
-Before today, we had many issues with storage even without the spike in users we are seeing since the last ten days.
-
-## Context on AWS
-
-Amazon AWS, recently gave credits to the Falco project to operate some parts of the infrastructure on AWS. The CNCF is providing a sub-account we are already using for the migration of the other pieces (like Prow).
-
-## Interactions with other teams and the CNCF
-
-* The setup on the AWS account side already done, this is all technical work.
-
-* We need to open a CNCF service account ticket for the download.falco.org subdomain to point to the S3 bucket we want to use
-
-## The Plan
-
-We want to propose to move the drivers and the container dependencies to S3.
-
-#### Moving means:
-
-* We create a public S3 bucket with [stats enabled](https://docs.aws.amazon.com/AmazonS3/latest/dev/analytics-storage-class.html)
-
-* We attach the bucket to a cloudfront distribution behind the download.falco.org subdomain
-
-* We move the current content keeping the same web server directory structure
-
-* We change the Falco Dockerfiles and driver loader script accordingly
-
-* We update test-infra to push the drivers to S3
-
-* Once we have the drivers in S3, we can ask bintray to relax the limits for this month so that our users are able to download the other packages we keep there. Otherwise they will have to wait until November 1st. We only want to do that after the moving because otherwise we will hit the limits pretty quickly.
-
-#### The repositories we want to move are:
-
-* [https://bintray.com/falcosecurity/driver](https://bintray.com/falcosecurity/driver) will become https://download.falco.org/driver
-
-* [https://bintray.com/falcosecurity/dependencies](https://bintray.com/falcosecurity/dependencies) will become https://download.falco.org/dependencies
-
-#### Changes in Falco
-
-* [Search for bintray ](https://github.com/falcosecurity/falco/search?p=2&q=bintray)on the Falco repo and replace the URL for the CMake and Docker files.
-
-* It’s very important to change the DRIVERS_REPO environment variable [here](https://github.com/falcosecurity/falco/blob/0a33f555eb8e019806b46fea8b80a6302a935421/CMakeLists.txt#L86) - this is what updates the falco-driver-loader scripts that the users and container images use to fetch the module
-
-#### Changes in Test Infra
-
-* We need to use the S3 cli instead of jfrog cli to upload to the s3 bucket after building [here](https://github.com/falcosecurity/test-infra/blob/master/.circleci/config.yml)
-
-* We can probably remove jfrog from that repo since it only deals with drivers and drivers are being put on S3 now
-
-* Instructions on how to setup the S3 directory structure [here](https://falco.org/docs/installation/#install-driver)
-
-    * `/$driver_version$/falco_$target$_$kernelrelease$_$kernelversion$.[ko|o]`
-
-#### Changes to Falco website
-
-* Changes should not be necessary, we are not updating the way people install Falco but only the driver. The driver is managed by a script we can change.
-
-## Mitigation and next steps for the users
-
-* **The average users should be good to go now, Bintray raised our limits and we have some room to do this without requiring manual steps on your end**
-
-* **Users that can’t wait for us to have the S3 setup done: **can setup an S3 as driver repo themselves, push the drivers they need to it after compiling them (they can use [Driverkit](https://github.com/falcosecurity/driverkit) for that) Instructions on how to setup the S3 directory structure [here](https://falco.org/docs/installation/#install-driver).
-
-* **Users that can’t wait but don’t want to setup a webserver themselves**: the falco-driver-loader script can also compile the module for you. Make sure to install the kernel-headers on your nodes.
-
-* **Users that can wait** we will approve this document and act on the plan described here by providing the DRIVERS_REPO at  [https://download.falco.org/driver](https://download.falco.org/driver) that then you can use
-
-### How to use an alternative DRIVERS_REPO ?
-
-**On bash:**
-
-export DRIVERS_REPO=https://your-url-here
-
-**Docker**
-
-Pass it as environment variable using the docker run flag -e - for example:
-
-docker run -e DRIVERS_REPO=[https://your-url-here](https://your-url-here)
-
-**Kubernetes**
-
-spec:
-
-  containers:
-
-  - env:
-
-    - name: DRIVERS_REPO
-
-      value: https://your-url-here
-
-## Release
-
-Next release is on December 1st, we want to rollout a hotfix 0.26.2 release that only contains the updated script before that date so that users don’t get confused and we can just tell them "update Falco" to get the thing working again.

-# OSS Libraries Donation Plan
-
-## Summary
-
-Sysdig Inc. intends to donate **libsinsp**, **libscap**, the **kernel module driver** and the **eBPF driver sources** by moving them to the Falco project.
-
-This means that some parts of the [draios/sysdig](https://github.com/draios/sysdig) repository will be moved to a new GitHub repository called [falcosecurity/libs](https://github.com/falcosecurity/libs).
-
-This plan aims to describe and clarify the terms and goals to get the donation done.
-
-## Motivation
-
-There are two main OSS projects using the libraries and drivers that we are aware of:
-
-- [sysdig](https://github.com/draios/sysdig)  the command line tool
-- [Falco](https:/github.com/falcosecurity/falco), the CNCF project.
-
-Since the Falco project is a heavy user of the libraries, a lot more than the sysdig cli tool, Sysdig (the company) decided to donate the libraries and the driver to the Falco community.
-
-Sysdig (the command line tool) will continue to use the libraries now provided by the Falco community underneath.
-
-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.
-
-- Given the previous point, Sysdig (the command line tool) will benefit from the now **extended contributors base**
-
-- Sysdig (the company) can now focus on the user experience and user space features
-
-- **Contributions** to the libraries and drivers will be **easier** to spread across the Falco community
-
-- By being donated, with their own **release process**, **release artifacts**, and **documentation**, the libraries can now live on their own and possibly be used directly in other projects by becoming fundamental pieces for their success.
-
-## Goals
-
-There are many sub-projects and each of them interacts in a different way in this donation.
-
-Let's see the goals per sub-project.
-
-### libsinsp
-
-1. Extract libsinsp from `draios/sysdig/userspace/libsinsp` (keeping the commit history) into [falcosecurity/libs](https://github.com/falcosecurity/libs)
-
-2. The migration comes first, then we can do additional PRs for the points below so that we do only one thing at a time and keep the history linear
-
-3. Keep the same code, refactorings will need to be done in subsequent PRs and approved separately
-
-4. Adapt the CMake and build files
-
-5. Install [poiana](https://github.com/poiana) and its workflows on it
-
-6. Define the `OWNERS`
-
-   - Owners are chosen from the current major contributors (considering the past two years) to this project, given their availability, commitment is key
-
-7. When possible, migrate issues and PRs to the new repository
-
-8. Distribute the `libsinsp.so` library and headers as an artifact (rpm, deb, tar.gz) following the falcosecurity current process
-
-9. Distribute the `libsinsp.a` library and headers as an artifact (rpm, deb, tar.gz) following the falcosecurity current process
-
-10. Creation of the CI scripts using the Falco CI and Falco Infra
-
-11. The CI scripts will need to publish the artifacts in the current falcosecurity artifacts repository
-
-12. Artifacts will be pushed for every tag (release) and for every master merge (development release)
-
-13. Falco follows a [multi-stage model for adopting new projects](https://github.com/falcosecurity/evolution#falco-project-evolution), in this case we will do an exception since the library is foundational for Falco and it has a very good track record already
-
-14. This project will go already "Official support" once the donation is completed
-
-15. Contributing, Code of Conduct, Governance, Security, and Support will be the same as the rest of the organization, find them [here](https://github.com/falcosecurity/.github)
-
-16. Every other additional change will need to have its own process with a proposal
-
-17. Implement the release process as described above
-

-
-19. Document the API

Falco follows a [multi-stage model for adopting new projects](https://github.com/falcosecurity/evolution#falco-project-evolution), in this case we will do an exception since the library is foundational for Falco and it has a very good track record already. We are just changing maintenance ownership
-
-9. Contributing, Code of Conduct, Governance, Security, and Support will be the same as the rest of the organization, find them [here](https://github.com/falcosecurity/.github)
-
-10. Every other additional change will need to have its own process with a proposal
-
-11. The Falco community already ships driver artifacts using [driverkit](https://github.com/falcosecurity/driverkit) and the [test-infra repository](https://github.com/falcosecurity/test-infra)
-
-    - Adapt the place from which [driverkit](https://github.com/falcosecurity/driverkit) grabs the drivers source
-
-12. This project will go already "Official support" once the migration is completed.
-
-### Falco
-
-1. Adapt the CMake files to point to the new homes for libscap, libsinsp and the drivers
-
-2. When distributing the deb and rpm, libscap and libsinsp will need to be install dependencies and not anymore compiled into Falco
-
-### Driverkit
-
-1. Change the source location for the drivers to point to the new driver repository
-
-### pdig
-
-1. The project will need to be adapted to use libscap and libsinsp and the fillers from their new location

-
-Also, it assumes you prepared [falco_traces](#falco_traces) (see the section below) and you already run the following command from the build directory:
-

-
-### falco_traces
-
-The `falco_traces.yaml` test suite gets generated through the `falco_traces.yaml.in` file and some fixtures (`scap` files) downloaded from the web at execution time.
-
-1. Ensure you have `unzip` and `xargs` utilities
-2. Prepare the test suite with the following command:
-
-    ```console
-    bash run_regression_tests.sh -p -v
-    ```
-
-### falco_tests_package
-
-The `falco_tests_package.yaml` test suite requires some additional setup steps to be succesfully run on your local machine.
-
-In particular, it requires some runners (ie., docker images) to be already built and present into your local machine.
-
-1. Ensure you have `docker` up and running
-2. Ensure you build Falco (with bundled deps)
-
-    The recommended way of doing it by running the `falcosecurity/falco-builder` docker image from the project root:
-
-    ```console
-    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder cmake
-    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder falco
-    ```
-
-3. Ensure you build the Falco packages from the Falco above:
-
-    ```console
-    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder package
-    ```
-
-4. Ensure you build the runners:
-
-    ```console
-    FALCO_VERSION=$(./mybuild/release/userspace/falco/falco --version  | head -n 1 | cut -d' ' -f3 | tr -d '\r')
-    mkdir -p /tmp/runners-rootfs
-    cp -R ./test/rules /tmp/runners-rootfs
-    cp -R ./test/trace_files /tmp/runners-rootfs
-    cp ./mybuild/release/falco-${FALCO_VERSION}-x86_64.{deb,rpm,tar.gz} /tmp/runners-rootfs
-    docker build -f docker/tester/root/runners/deb.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-deb /tmp/runners-rootfs
-    docker build -f docker/tester/root/runners/rpm.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-rpm /tmp/runners-rootfs
-    docker build -f docker/tester/root/runners/tar.gz.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-tar.gz /tmp/runners-rootfs
-    ```
-
-5. Run the `falco_tests_package.yaml` test suite from the `test` directory
-
-    ```console
-    cd test
-    BUILD_DIR="../mybuild" avocado run --mux-yaml falco_tests_package.yaml --job-results-dir /tmp/job-results -- falco_test.py
-    ```
-
-### Execute all the test suites
-
-In case you want to run all the test suites at once, you can directly use the `run_regression_tests.sh` runner script.
-
-```console
-cd test
-./run_regression_tests.sh -v
-```
-
-Just make sure you followed all the previous setup steps.
