85e25cb0d9 Skip EPF_TABLE_ONLY fields with --list -N
When listing fields with -N (names only), also skip fields with the
EPF_TABLE_ONLY flag. (Skipping fields without -N is handled in libs,
in the as_string() method).

f4b79296fc fix: improve nested configuration field support
This fixes the parser introduced in https://github.com/falcosecurity/falco/pull/1792.
Now, nested fields such as `arr[1].subval` are supported, whereas the parser used
to recognize the `.` as an unexpected character.

c86615f68c Embed .lua files into falco executable
Instead of having .lua files external to the program responsible for
loading rules, embed the contents of those files into the executable
and load them as strings instead of as files:

Add a cmake custom command below userspace/engine/lua that calls a
bash script lua-to-cpp.sh to generate falco_engine_lua_files.{cpp,hh}
that are compiled into the falco engine library.

The script creates a .cpp file that has const char * symbols for each
file, as well as lists of files that should be loaded when the falco
engine is loaded. There are actually two lists:

- lua_module_strings: these are loaded and also added to the lua
  runtime package.preload table, so they are available when lua code
  require()s them.

- lua_code_strings: these are loaded *and* evaluated, so the functions
  in them are availble to be called from C++.

This simplifies some of the falco_common methods, as there's no need
to keep track of a "main" lua file to load or paths from which the lua
loader should find files for modules, and there's no need to keep
track of an "alternate" lua directory that occurs for debug builds.

Also, there's no need to include any .lua files in the installed
packages, as they're built into the falco binary.

08df1c63cf Clean up lyaml build a bit
change LYAML_SRC to LYAML_ROOT, which points to the top source
directory now.

LYAML_LIB and (new) LYAML_LUA_DIR are based relative to that
directory.

There's no install step at all now--the static library and the .lua
files are now used directly from the source tree.

eded1062cd Use filter_fieldclass_info::as_string to print field info
Instead of having a falco-specific function to print field info, use
the built-in filter_fieldclass_info::as_string() instead. This is a
better implementation (displays addl info, has better wrapping, wider
output) and having a single implementation allows for consistent
outputs between falco and other potential programs that could use the libs.

7781385769 refactor(engine): support string config loading and add ad-hoc methods
This is a change of direction from the current design, that imposes loading
the configuration from file only, and in the object constructor. Instead,
yaml_configuration objects can now be reused ad can load the YAML config
from either file or string. This also makes it easier to unit test this class.

2a4e4d555d Add automated tests for plugins
Test infrastructure and sample confs/rules/traces for plugins
automated tests:

New test cases are in falco_tests_plugins.yaml and cover:
- Listing plugins and fields when plugins are loaded.
- Basic cloudtrail + json plugin on a fake cloudtrail json file and a
  sample rule that uses both plugins.
- Conflicts between source/extractor plugins
- Incompatible plugin api
- Wrong plugin path
- Checking for warnings when reading rules with unnown sources (e.g. when plugins are not loaded)

Some test-only plugins written in C are in test/plugins and built on
the fly. (They aren't included in packages of course).

The test framework needed some small changes to handle these tests:
- Add a mode to not check detection counts at all (for --list/--list-plugins)
- addl_cmdline_opts to allow specifying --list/--list-plugins
- Using DOTALL when matching stderr/stdout (allows multi-line matches more easily)

6a1f4f7374 Plugins support in falco executable
Update the falco binary to add support for plugins.

- Keep track of an "event source", which is initially "syscall" but
  changes to the input plugin's source if an source plugin ends up being
  loaded.

- New argument --list-plugins will return info on any loaded plugins,
  using sinsp_plugin::plugin_infos.

- Create filter/formatter factories for plugins. This ensures that
  filterchecks for syscalls are not used for plugins and vice versa.

- Use sinsp_plugin::register_plugin() to load each plugin found in
  config. The first source plugin found (if any) calls
  engine->add_source withthe source plugin's event source.

- If a second source plugin is found, exit with an error.

- Extractor plugins must be compatible with the event source (usually
  the plugin event source, but could be "syscall"). If not, exit with
  an error.

- Multiple Extractor plugins are allowed, but they can not have
  overlapping compatible event sources. This is mostly to avoid
  confusion, but we might change this later.

- After loading plugins, use engine is_plugin_compatible to ensure
  that the plugin is compatible with any required_plugin_version blocks
  in falco rules.

- Normally falco would log warnings if too many SCAP_TIMEOUT results
  were received. These are more expected when using plugins, so only
  log these warnings when using syscalls.

9075eea62f Falco engine support for plugins
Mostly plugins are just handled as a new filter/formatter factory with
a new source based on the loaded input plugin, but there are a few
changes at the engine level:

- is_source_valid returns whether a filter/formatter factory exists
  for a given source. Will be used by rules loaded to skip rules for
  an unknown source.

- the falco engine now holds the required_plugin_version predicates
  found in rules files and a method is_plugin_compatible returns whether
  a plugin semver is compatible with the predicates in the rules

- Update the falco engine version and fields checksum for plugins

f7893fbd14 Change expected result for old trace file with old execve event num
The trace file traces-positive/run-shell-untrusted.scap has an old
execve event number (PPME_SYSCALL_EXECVE_18), which was replaced by
PPME_SYSCALL_EXECVE_19 in 2018.

Given the changes in https://github.com/falcosecurity/libs/pull/94,
these events are now skipped. So change the test to note that *no*
events will be detected.

As a bit of context, event numbers won't be changing any longer--a
change around the same time 298fbde8029020ce3fbddd07e2910b59cc402b8b
allowed for extending existing events to add new parameters instead of
having to define a new event number just to add a new parameter. So
the notion of "old events" should not exist for any event created
after mid-to-late 2018.

3b390793b9 Fix bug in macro that was masked by old evttype checking
It turns out that the macro inbound_outbound had a logical bug where
joining the beginning and end of the macro with "or" led to the macro
matching all event types by accident.

Most of the time this isn't harmful but it turns out some trace files
will do operations on inet connection fds like "dup", and those get
mistakenly picked up by this macro, as the fd for the event does
happen to be a network connection fd.

This fixes the macro to only match those event types *and* when the fd
is a inet connection fd.

10d47cb1f5 Update automated tests to reflect evttypes behavior
With the changes in https://github.com/falcosecurity/libs/pull/74,
there isn't any need to warn about the order of operators and the
evt.type field--the set of event types for a filter should be exact
now regardless of the order of operators.

So update tests that were logging those warnings to note that the
warnings won't occur any more.

Also, some tests more accurately *do* note that they have an overly
permissive evttype (e.g. ones related to syscalls, which are uncommon
and are evaluated for all event types) to reflect the new behavior.

Finally, in unit tests create an actual sinsp filter instead of a
gen_event_filter, which is the base class and shouldn't be created
directly.

Update the lua side of rule loading to reflect other changes:

  uses a single lua callback "filter" instead of separate ones for
  syscall/k8s_audit. It can return an error, including about
  undefined fields

- is_defined_filter, which used to be local and based on the result of
  sinsp_rule_utils.check_for_ignored_syscalls_events, is now a
  lua_callback falco_rules.is_defined_field().

- Don't need to pass down sinsp_lua_parser/json_lua_parser now,
  creating filters is handled via lua callbacks.

- Checking for ignored syscalls/events is now done in falco itself,
  after loading rules.

- add_xxx_filter replaced by add_filter + source.

- Use is_format_valid instead of formats.formatter/formats.free_formatter.

bbbac6203c Update rules loader to be general purpose, through factories
Update rules loader to be more general purpose by using factories and
the general purpose engine:

- A lua callback create_lua_parser creates a lua_parser with a filter
  object of the right type. The lua parser can then iterate the AST
  and populate the filter object.

- Like the falco engine, the rules loader is configured with a list of
  factories, and add_filter is now general purpose, taking a source.

Given the fix in https://github.com/falcosecurity/libs/pull/72, there
isn't any need to pass down the entire set of sinsp event
types/syscalls and validate that all filter event types are
valid. That job is now handled by the sinsp filter parsing
code. add_filter now returns the number of event types used by the new
filter, and if that number is excessive the lua code will return a
warning.

Format handling is mostly not handled by the rules loader any more. As
a convienence, there's a new lua callback is_format_valid which takes
a source and output string and uses the right formatter factory to
create a formatter. As long as that doesn't throw an exception, the
format is valid.

8275730bf8 Use factories to provide filters/formatting
Instead of having hard-coded support for syscall/k8s_audit events, use
the notions of filter factories/formatter factories to provide generic
support for events having a given source:

- Within the engine, maps m_filter_factories / m_rulesets /
  m_format_factories map from a given source to something that can
  create filters, hold filters, and create formatters for a given
  source. The hard-coded sinsp_factory/json_factory objects are removed.

- The specific add_xxx_filter/process_xxx_event are general purpose
  and take an event source.

- A new method create_formatter() takes a source/output format and
  provides a shared_ptr to a formatter than can resolve format
  strings. This is used by the falco outputs code.

- In falco main, create the syscall/k8s_audit filter and formatter
  factories and pass them to the engine. Later, we might make this
  configurable/selective.

With all of the above changes, the falco engine doesn't need a direct
inspector any longer, so remove it.

Modify rulesets to not keep track of the event types for a given set

Within each ruleset, there's a vector that maps from event number to
set of filters that are related to that event number. There's also a
general set of filters for all event types.

run() both indexes into the per-event vector as well as iterate over
the all event types set.

Also, used shared_ptr instead of direct pointers, which matches the
updated interface used by lua_parser. This simplifies the bookkeeping
a bit (no more delete when removing rulesets).

Given these changes, there's no need for a separate
falco_sinsp_ruleset class any longer, so remove it.

Furthermore, it never took effect since the builder image was never built and pushed. For the same reason, we have not noticed it until now.

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

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

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

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

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

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

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

...
  "engine_info": {
      "engine_version": 8

f14b37984c Add test for some containers being privileged
Add a test that verifies that a pod where one container has no security
context and the second container has a security context + privileged
properly matches the Create Privileged Pod falco rule.

There's a very similar test case already in
trace_files/k8s_audit/create_nginx_pod_privileged_2nd_container.json,
but in that case both containers have a securityContext property.

ecccb9f26c Extract array miss as "no value" vs failed extract
While testing, I found a case when creating a pod where:
1) the first container had no securityContext value
2) the second container had a security context with privileged=true

and this did not match the default rule Create Privileged Pod, when it
should match.

The rule Create Privileged Pod uses the field
ka.req.pod.containers.privileged, which in turn uses
json_event_filter_check::def_extract(). def_extract() iterates
over a set of json_pointers, potentially expanding arrays as they are
returned. Many k8s audit fields use this extract function.

For ka.req.pod.containers.privileged, the first json_pointer is
/requestObject/spec/containers to find the list of containers, and the
second is /securityContext/privileged to extract the privileged property
out of the securityContext object. What's returned is an array of
true/false noting if each container is privileged.

The problem is that def_extract() aborts when iterating over arrays if
extracting a pointer from an array can't be done.

In this case, the first pointer extracts the array of containers, and
then when iterating over the array of containers, the security context
pointer doesn't extract, causing the whole filter field to abort and
return ::no_value.

The fix is to not abort when iterating over arrays, but use ::no_value
for that array item's value instead. This allows def_extract() to
extract the privileged value out of the second container.

04110b0f4c chore(scripts): restore mount of debugfs (notes below)
This is needed in systems where raw tracepoints are not available.

Anyways, since this is needed when the inspector open (and actually
loads) the eBPF probe, ideally the mount should not be done by this
script but rather from Falco, or from Falco libs.

Otherwise, users building the eBPF probe theirseleves and not using this script (and having a kernel without raw
tracepoints) may need to mount this fs theirselves.

3da5dfa67b Properly parse numbers in condition fields
Falco won't properly parse a rule like this:

---
- rule: Some Rule
  desc: Some Desc
  condition: evt.type=execve and container.image.repository = 271931939120.dkr
  output: Some output
  priority: INFO
---

This is the error when validating the rules:

Tue Mar 30 12:00:40 2021: Validating rules file(s):
Tue Mar 30 12:00:40 2021:    /home/mstemm/test.yaml
1 errors:
Compilation error when compiling "evt.type=execve and container.image.repository = 271931939120.dkr": 63: syntax error, unexpected 'dkr', expecting 'or', 'and'

The parsing of the string on the right hand side stops at the period
before the dkr. The dkr then doesn't match the grammar, resulting in the
error.

Looking at the parser implementation more closely, the problem is in the
definition of "Number":

---
-   Number = C(V "Hex" + V "Float" + V "Int") / function(n)
          return tonumber(n)
       end,
---
Note that it stops after the number, but does not have any requirement
about what follows.

This changes the definition of number to require that what follows the
number is not an identifier character. With this change, values that are
only numbers are parsed as numbers, and values that start with numbers
don't match the Number definition and are parsed as BareStrings instead.

64a231b962 Add exceptions fields/comps/values to rules files
Take advantage of the changes to support exceptions and refactor rules
to use them whenever feasible:

- Define exceptions for every rule. In cases where no practical
  exception exists e.g. "K8s <obj> Created/Deleted", define an empty
  exception property just to avoid warnings when loading rules.
- Go through all rules and convert macros-used-as-exceptions that
  matched against 2-3 filter fields into exceptions. In most cases,
  switching from equality (e.g proc.name=nginx) to in (e.g. proc.name
  in (nginx)) allowed for better groupings into a smaller set of
  exception items.
- In cases where the exception had complex combinations of fields, keep
  the macro as is.

a582599778 Support exceptions properties on rules
Support exceptions properties on rules as described in
https://github.com/falcosecurity/falco/pull/1376.

- When parsing rules, add an empty exceptions table if not specified.
- If exceptions are specified, they must contain names and lists of
  fields, and optionally can contain lists of comps and lists of lists of
  values.
- If comps are not specified, = is used.
- If a rule has exceptions and append:true, add values to the original rule's
  exception values with the matching name.
- It's a warning but not an error to have exception values with a name
  not matching any fields.

After loading all rules, build the exception condition string based on
any exceptions:

- If an exception has a single value for the "fields" property, values are
  combined into a single set to build a condition string like "field
  cmp (val1, val2, ...)".
- Otherwise, iterate through each rule's exception
  values, finding the matching field names (field1, field2, ...) and
  comp operators (cmp1, cmp2, ...), then
  iterating over the list of field values (val1a, val1b, ...), (val2a,
  val2b, ...), building up a string of the form:
    and not ((field1 cmp1 val1a and field2 cmp2 val1b and ...) or
              (field1 cmp1 val2a and field2 cmp2 val2b and ...)...
	     )"
- If a value is not already quoted and contains a space, quote it in the
  string.

verbose is true:

 - load_rules now returns a tuple (success, required engine version,

   version) or (false, error string)
 - build_error/build_error_with_context now returns an array instead of
   string value.
 - warnings are combined across calls to load_rules_doc
 - Current warnings include:
   - a rule that contains an unknown filter
   - a macro not referred to by any rule
   - a list not referred to by any rule/macro/list

Any errors/warnings are concatenated into the exception if success was
false. Any errors/warnings will be printed if verbose is true.

This proposes adding exceptions as a first class object to falco rules
files.

It adds a new key "exceptions" to rule objects that allows a rule
writer to define tuples of field names that comprise an exception, and a
new top level object "exception" that contains lists of tuples of field
values that define exceptions to rules.

d03a1f4a9b feature(grpc): Add engine version to version svc
Fixes #1269

Add two new fields in the version service for falco's engine version and
the checksum of all of the fields it understands.

This will require rebuilding/re-releasing all the clients.

4d6636a030 fix(scripts/falco-driver-loader): lsmod usage
Attempting to start falco on a host that had a similarly named module
(e.g., "falcon") would cause the falco-driver-loader to loop attempting
to rmmod falco when falco was not loaded.

falco-driver-loader will now inspect only the first column of lsmod
output and require the whole search string to match

# Adopters
Known end users with notable contributions to the project include:
* AWS
* IBM
* Red Hat
Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
* Equinix Metal
* IEEE
* Lowes
* Reckrut
* Yellow Pepper
* CTx
* Utikal
* Discrete Events
* Agritech Infra
This is a list of production adopters of Falco (in alphabetical order):
* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. 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 with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
* [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.
* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
* [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.
* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containerswhich 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.

* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. 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.
* https://logz.io/blog/k8s-security-with-falco-and-cloud-siem/
* [MathWorks](https://mathworks.com) - MathWorks develops mathematical computing software for engineers and scientists. MathWorks uses Falco for Kubernetes threat detection, unexpected application behavior, and maps Falco rules to their cloud infrastructure's security kill chain model. MathWorks presented their Falco use case at [KubeCon + CloudNativeCon North America 2020](https://www.youtube.com/watch?v=L-5RYBTV010).
* [Pocteo](https://pocteo.co) - Pocteo helps with Kubernetes adoption in enterprises by providing a variety of services such as training, consulting, auditing and mentoring. We build CI/CD pipelines the GitOps way, as well as design and run k8s clusters. Pocteo uses Falco as a runtime monitoring system to secure clients' workloads against suspicious behavior and ensure k8s pods immutability. We also use Falco to collect, process and act on security events through a response engine and serverless functions.
* [Preferral](https://www.preferral.com) - Preferral is a HIPAA-compliant platform for Referral Management and Online Referral Forms. Preferral streamlines the referral process for patients, specialists and their referral partners. By automating the referral process, referring practices spend less time on the phone, manual efforts are eliminated, and patients get the right care from the right specialist. Preferral leverages Falco to provide a Host Intrusion Detection System to meet their HIPPA compliance requirements.

* [Sumo Logic](https://www.sumologic.com/) - Sumo Logic provides a SaaS based log aggregation service that provides dashboards and applications to easily identify and analyze problems in your application and infrastructure. Sumo Logic provides native integrations for many CNCF projects, such as Falco, that allows end users to easily collect Falco events and analyze Falco events on DecSecOps focused dashboards.
* [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-define infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
* [Swissblock Technologies](https://swissblock.net/) At Swissblock we connect the dots by combining cutting-edge algorithmic trading strategies with in-depth market analysis. 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. A set of alarms notifies us in case of critical events, letting us react fast. In the near future we plan to build a little application to route Kubernetes internal events directly to Falco, fully leveraging Falco PodSecurityPolicies analyses.
* [Shapesecurity/F5](https://www.shapesecurity.com/) Shapesecurity defends against application fraud attacks like Account Take Over, Credential Stuffing, Fake Accounts, etc. Required by FedRamp certification, we needed to find a FIM solution to help monitor and protect our Kubernetes clusters. Traditional FIM solutions were not scalable and not working for our environment, but with Falco we found the solution we needed. Falco's detection capabilities have helped us identify anomalous behaviour within our clusters. We leverage Sidekick (https://github.com/falcosecurity/charts/tree/master/falcosidekick) to send Falco alerts to a PubSub which in turn publishes those alerts to our SIEM (SumoLogic)
* [Yahoo! JAPAN](https://www.yahoo.co.jp/) Yahoo! JAPAN is a leading company of internet in Japan. We build an AI Platform in our private cloud and provide it to scientists in our company. AI Platform is a multi-tenant Kubernetes environment and more flexible, faster, more efficient Machine Learning environment. Falco is used to detect unauthorized commands and malicious access and our AI Platform is monitored and alerted by Falco.

## Projects that use Falco libs
* [R6/Phoenix](https://r6security.com/) is an attack surface protection company that uses moving target defense to provide fully automated, proactive and devops friendly security to its customers. There are a set of policies you can add to enable the moving target defense capabilities. Some of them are triggered by a combination of Falco's findings. You can kill, restart and rename pods according to the ever changing policies.
* [SysFlow](https://sysflow.io) SysFlow is a cloud-native system telemetry framework that focuses on data abstraction, behavioral analytics, and noise reduction. At its core, SysFlow exposes a compact open telemetry format that records workload behaviors by connecting event and flow representations of process control flows, file interactions, and network communications. The resulting abstraction encodes a graph structure that enables provenance reasoning on host and container environments, and fast retrieval of security-relevant information.

# 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 rule set of security rules specifically built for Kubernetes, Linux, and cloud-native.
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.

# Why we mirror jq here?
#
# In their readme, jq claims that you don't have
# to do autoreconf -fi when downloading a released tarball.
#
# However, they forgot to push the released makefiles
# into their release tarbal.
#
# For this reason, we have to mirror their release after
# doing the configuration ourselves.
#
# This is needed because many distros do not ship the right
# version of autoreconf, making virtually impossible to build Falco on them.
# Read more about it here:

* docker run -ti falcosecurity/falco-builder bash
To build Falco it needs:
- a bind-mount on the source directory (ie., the directory containing Falco and sysdig source as siblings)
- a bind-mount on the source directory (ie., the directory containing the Falco source as sibling)
Optionally, you can also bind-mount the build directory.
So, you can execute it from the Falco root directory as follows.

# 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.

# OSS Libraries Contribution 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 contribution 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 **contribution** 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 contribution.
Let's see the goals per sub-project.
### libsinsp

# Plugin System
## Summary
This is a proposal to create an infrastructure to extend the functionality of the Falco libraries via plugins.
Plugins will allow users to easily extend the functionality of the libraries and, as a consequence, of Falco and any other tool based on the libraries.
This proposal, in particular, focuses on two types of plugins: source plugins and extractor plugins.
## Motivation
[libscap](https://github.com/falcosecurity/libs/tree/master/userspace/libscap) and [libsinsp](https://github.com/falcosecurity/libs/tree/master/userspace/libsinsp) provide a powerful data capture framework, with a rich set of features that includes:
- data capture
- trace files management
- enrichment
- filtering
- formatting and screen rendering
- Lua scripting (chisels)
These features have been designed with one specific input in mind: system calls. However, they are generically adaptable to a broad set of inputs, such as cloud logs.
With this proposal, we want to dramatically extend the scope of what the libraries, Falco and other tools can be applied to. We want to do it in a way that is easy, efficient and empowers anyone in the community to write a plugin.
## Goals
- To design and implement a plugin framework that makes the libraries more modular and extensible
- To have a framework that is easy to use
- To support dynamic loading of plugins, so that the libraries can be extended without having to be recompiled and relinked
- To enable users to write plugins in any language, with a particular focus on Go, C and C++
- To have an efficient plugin framework so that, performance-wise, writing a plugin is as close as possible as extending the libraries internal source code
- To make it possible to write plugins for Linux, MacOS and Windows
## Non-Goals
- To implement plugins other than source and extractor: to be approached as separate task
- To document the plugin framework and interface: to be approached as separate task
## Proposal
### Plugin Common Information
Both source and extractor plugins have the following:
- A required api version, to ensure compatibility with the plugin framework.
- A name
- A description
- A version
- A contact field for the plugin authors (website, github repo, twitter, etc).
- Functions to initialize and destroy the plugin internal state.
### Plugin types
Initially, we will implement support for two types of plugins: source plugins and extractor plugins.
#### Source Plugin
A source plugin implements a new sinsp/scap event source. It has the ability to "open" and "close" a session that provides events. It also has the ability to return an event to the plugin framework via a next() method. Events returned by source plugins have an "event source", which describes the information in the event. This is distinct from the plugin name to allow for multiple kinds of plugins to generate the same kind of events. For example, there might be plugins gke-audit-bridge, eks-audit-bridge, ibmcloud-audit-bridge, etc. that all fetch [K8s Audit](https://kubernetes.io/docs/tasks/debug-application-cluster/audit/) information. The plugins would have different names but would have the same event source "k8s_audit".
Source plugins also have the ability to extract information from events based on fields. For example, a field proc.name extracts a process name from a syscall event. The plugin returns a set of supported fields, and there are functions to extract a value given an event and field. The plugin framework can then build filtering expressions/Falco rule conditions based on these fields combined with relational and/or logical operators. For example, given an expression "ct.name=root and ct.region=us-east-1", the plugin framework handles parsing the expression, calling the plugin to extract values for a given event, and determining the result of the expression. In a Falco output string like "An EC2 Node was created (name=%ec2.name region=%ct.region)", the plugin framework handles parsing the output string, calling the plugin to extract values for a given event, and building the resolved string.
Source plugins also provide an "id", which is globally unique and is used in capture files (see below).
#### Extractor Plugin
An extractor plugin focuses only on field extraction from events generated by other plugins, or by the core libraries. It does *not* provide an event source, but can extract fields from other event sources. An example is json field extraction, where a plugin might be able to extract fields from arbitrary json payloads.
An extractor plugin provides an optional set of event sources. When the framework receives an event with an event source in the plugin's set of event sources, fields in expressions/Falco outputs will be extracted from events using the plugin. An extractor plugin can also *not* name a set of event sources. In this case, fields will be extracted from *all* events, regardless of source. In this case, the exctractor plugin must detect the format of arbitrary payloads and be able to return NULL/no value when the payload is not supported.
### Support for Plugin Events in Capture Files.
libscap will define a new event type called "pluginevent" that contains two fields:
* "plugin ID": This uniquely identifies the plugin that generated this event.
* "event_data": This is a variable-length data buffer containing the event data, as returned by the plugin.
Defining an event for plugins allows creating capture files from plugins. These capture files can be saved, read, filtered, etc, like any other capture file, allowing for later analysis/display/etc.
### Plugins format
Plugins are dynamic libraries (.so files in Unix, .dll files in windows) that export a minimum set of functions that the libraries will recognize.
Plugins are versioned using semantic versioning to minimize regressions and compatibility issues.
Plugins can be written in any language, as long as they export the required functions. Go, however, is the preferred language to write plugins, followed by C/C++.
### Protecting from plugin issues
The libraries will do everything possible to validate the data coming from the plugins and protect Falco and the other consumers from corrupted data. However, for performance reasons, plugins will be "trusted": they will run in the same thread and address space as Falco and they could crash the program. We assume that the user will be in control of plugin loading and will make sure only trusted plugins are loaded/packaged with Falco.
### Plugin/Event Source registries
Every source plugin requires its own, unique plugin ID to interoperate with Falco and the other plugins. The plugin ID will be used by the libs to properly process incoming events (for example, when saving events to file and loading them back), and by plugins to unuambiguosly recognize their dependencies.
To facilitate the allocation and distribution of plugin IDs, we will require that plugin developers request IDs for their plugins to the Falco organization. The mechanism used for plugin allocation is not determined yet and will be discussed in the future.
Similarly, plugin developers must register event sources with the Falco organization. This allows coordination between plugins that wish to provide compatible payloads, and to allow extractor plugins to know what data format is associated with a given event source.
### golang plugin SDK
To facilitate the development of plugins written in go, an SDK has been developed. We intend this SDK (and future SDKs for other languages) to be part of the Falco organization. For this reason, we submitted the following incubation request: https://github.com/falcosecurity/evolution/issues/62
### Proposed API (subject to change)

// below in next()/next_batch().
// - data: pointer to a memory buffer pointer. The plugin will set it
// to point to the memory containing the next event. Once returned,
// the memory is owned by the plugin framework and will be freed via
// a call to free().
// - datalen: pointer to a 32bit integer. The plugin will set it the size of the
// buffer pointed by data.
// - ts: the event timestamp. Can be (uint64_t)-1, in which case the engine will
// automatically fill the event time with the current time.

### Event Sources and Falco Rules
Falco rules already have the notion of a "source", using the source property in rules objects, and there are currently two kinds of event sources: "syscall" and "k8s_audit". We will use the source property in Falco rules to map a given rule to the event source on which the rule runs.
For example, given a plugin with source "aws_cloudtrail", and a Falco rule with source "aws_cloudtrail", the rule will be evaluated for any events generated by the plugin.
Similarly, an extractor plugin that includes "aws_cloudtrail" in its set of event sources will have the opportunity to extract information from aws_cloudtrail events if a matching field is found in the rule's condition, exception, or output properties.
This, combined with the restrictions below, allows a set of loaded rules files to contain a mix of rules for plugins as well as "core" syscall/k8s_audit events.
We will also make a change to compile rules/macros/lists selectively based on the set of loaded plugins (specifically, their event sources), instead of unconditionally as Falco is started. This is especially important for macros, which do not contain a source property, but might contain fields that are only implemented by a given plugin.
### Handling Duplicate/Overlapping Fields in Plugins/Libraries Core
At an initial glance, adding plugins introduces the possibility of tens/hundreds of new filtercheck fields that could potentially overlap/conflict. For example, what happens if a plugin defines a "proc.name" field? However, the notion of "event source" makes these potential conflicts managable.
Remember that field extraction is always done in the context of an event, and each event can be mapped back to an event source. So we only need to ensure that filtercheck fields are distinct for a given event source. For example, it's perfectly valid for an AWS Cloudtrail plugin to define a proc.name field, as the events generated by that plugin are wholly separate from syscall events. For syscall events, the AWS Cloudtrail plugin is not involved and the core libraries extract the process name for the tid performing a syscall. For AWS Cloudtrail events, the core libraries are not involved in field extraction and is performed by the AWS Cloudtrail plugin instead.
We only need to ensure the following:
* That only one plugin is loaded at a time that exports a given event source. For example, the libraries can load either a gke-audit-bridge plugin with event source k8s_audit, or eks-audit-bridge with event source k8s_audit, but not both.
* That for a mix of source and extractor plugins having the same event source, that the fields are distinct. For example, a source plugin with source k8s_audit can export ka.* fields, and an extractor plugin with event source k8s_audit can export a jevt.value[/...] field, and the appropriate plugin will be used to extract fields from k8s_audit events as fields are parsed from condition expressions/output format strings.
### Plugin Versions and Falco Rules
To allow rules files to document the plugin versions they are compatible with, we will add a new top-level field `required_plugin_versions` to the Falco rules file format. The field is optional, and if not provided no plugin compatibility checks will be performed. The syntax of `required_plugin_versions` will be the following:
```yaml
- required_plugin_versions:
- name: <plugin_name>
version: x.y.z
...
```
Below required_plugin_versions is a list of objects, where each object has `name` and `version` properties. If a plugin is loaded, and if an entry in `required_plugin_versions` has a matching name, then the loaded plugin version must be semver compatible with the version property.
Falco can load multiple rules files, and each file may contain its own `required_plugin_versions` property. In this case, name+version pairs across all files will be merged, and in the case of duplicate names all provided versions must be compatible.
### Loading the plugins
The mechanics of loading a plugin are implemented in the libraries and leverage the dynamic library functionality of the operating system (dlopen/dlsym in unix, LoadLibrary/GetProcAddress in Windows). The plugin loading code also ensures that:
- the plugin is valid, i.e. that it exports the set of expected symbols
- the plugin has an api version number that is compatible with the libraries instance
- that only one source plugin is loaded at a time for a given event source
- if a mix of source and extractor plugins are loaded for a given event source, that the exported fields have unique names that don't overlap across plugins
#### Loading plugins in falcosecurity/libs
At the libraries level, loading plugins is handled via the static method:
```c++
void sinsp_plugin::register_plugin(sinsp* inspector, string filepath, char* config, ...)
```
filepath points to a dynamic library containing code that exports plugin API functions. config contains arbitrary config content which is passed to init().
Note that the code using the libraries is responsible for determining the location of plugin libraries and their configuration.
#### Loading plugins in falcosecurity/falco
Falco will control/configure loading plugins via the new "plugins" property in falco.yaml. Here's an example:
```yaml
plugins:
- name: aws_cloudtrail
library_path: aws_cloudtrail/plugin.so
init_config: "..."
open_params: "..."
- name: http_json
library_path: http_json/plugin.so
init_config_file: http_json/config.txt
open_params_file: http_json/params.txt
# Optional
load_plugins: [aws_cloudtrail]
```
A new "plugins" property in falco.yaml will define the set of plugins that can be loaded by Falco. The property contains a list of objects, with the following properties:
* name: Only used for load_plugins, but by convention should be the same as the value returned by the name() api function.
* library_path: a path to the shared library. The path can be relative, in which case it is relative to Falco's "share" directory under a "plugins" subdirectory e.g. /usr/share/falco/plugins.
* init_config: If present, the exact configuration text that will be provided as an argument to the init() function.
* init_config_file: If present, the provided file will be read and the contents will be provided as an argument to the init() function.
* open_params: If present, the exact params text that will be provided as an argument to the open() function.
* open_params_file: If present, the provided file will be read and the contents will be provided as an argument to the open() function.
For a given yaml object in the plugins list, only one of init_config/init_config_file and one of open_params/open_params_file can be provided at a time.
A new "load_plugins" property in falco.yaml will allow for loading a subset of the plugins defined in plugins. If present, only the plugins with the provided names will be loaded.
### Examples
We have an initial version working, consisting of:
* A version of falcosecurity/libs that supports the [plugin framework](https://github.com/falcosecurity/libs/tree/new/plugin-system-api-additions)
* Support code and examples for [writing plugins in go](https://github.com/mstemm/libsinsp-plugin-sdk-go/tree/new/plugin-system-api-additions)
* A [cloudtrail](https://github.com/mstemm/plugins/tree/new/plugin-system-api-additions) plugin that can generate events from cloudtrail logs and extract fields from those events.
* A version of Falco that uses all of the above to [load and evaluate rules with plugins](https://github.com/leogr/falco/tree/new/plugin-system-api-additions)
