910b8ff858 Fix(engine) Save parse positions when finding unresolved macros
Now that ASTs contain parse positions, use them when reporting errors
about unknown macros.

When doing the first pass to find all macro references, save macros as
a map<macro name,parse position> instead of a set<macro name>. While
making that change, change the visitor struct to use references
instead of pointers.

In the second pass, when reporting any unresolved macro references,
also report the parse position.

The unit tests also check that the positions of macros are properly
returned in the resolved/unresolved maps.

83b12bab1d Fix(engine): include parse positions in compile errors
Now that ASTs have parse positions and the compiler will return the
position of the last error, use that in falco rules to return errors
within condition strings instead of reporting the position as the
beginning of the condition.

This led to a change in the filter_ruleset interface--now, an ast is
compiled to a filter before being passed to the filter_ruleset
object. That avoids polluting the interface with a lot of details
about rule_loader contexts, errors, etc. The ast is still provided in
case the filter_ruleset wants to do indexing/analysis of the filter.

d0ceba83b4 update(cmake, docker, circleci): updated libs and driver to latest master.
Docker builder image was updated to remove the libelf and libz deps as they are now properly bundled, in BUNDLED_DEPS mode.
Finally, circleci musl job was updated to enforce the use of alpine-provided libelf package, since it is already static,
and building libelf on musl is pretty cumbersome.

acf5c4ce5f fix(engine): save syscall source only when processing events
The optimization in https://github.com/falcosecurity/falco/pull/2210
had a bug when the engine uses multiple sources at the same
time--m_syscall_source is a pointer to an entry in the indexed vector
m_sources, but if add_source is called multiple times, the vector is
resized, which copies the structs but invalidates any pointer to the
vector entries.

So instead of caching m_syscall_source in add_source(), cache it in
process_events(). m_sources won't change once processing events starts.

4a4fa2592b fix(plugins): trim whitespace in open_params
`open_params` is read from the falco YAML configuration file and parsed using Go's URL.

For example:
c349be6e84/plugins/k8saudit/pkg/k8saudit/source.go (L41-L42)

Go's URL parser does not handle whitespace, so if a user defines the `open_params` in the falco configuration file as follows

```yaml
open_params: >
/file/path
```

the parser returns an error. To avoid this, we now trim this parameter so no whitespace will be left for Go's URL parser to error out on.

For reference see #2262.

2d5fc0b647 Use the same falco_rule struct for every call to filter_ruleset
Instead of using a falco_rule struct on the stack, use a single value
inside the falco_source struct. It's mutable as find_source returns a
const struct.

At very high event volumes (> 1M syscalls/second), even the tiny time
it takes to create/destroy the struct starts to add up, and this
switch has some small cpu savings.

e5cd5eacf5 Save syscall source separately and check explicitly in process_event
When doing some testing of falco on very high event volumes (> 1.5M
events/second), I found that the time taken to look up a falco_source
struct had a non-negligible contribution to cpu usage.

So instead of looking up the source from the source_idx every time,
separately save the source for syscalls in the falco_engine object
directly. The separately saved copy is only used once someone calls
add_source with source="syscall".

7a5a4c32ee Support condition parse errors in rule loading results
In #2098 and #2158, we reworked how rules loading errors/warnings were
returned to provide a richer set of information, including
locations/context for the errors/warnings.

That did *not* include locations within condition expressions,
though. When parsing a condition expression resulted in a
warning/error, the location simply pointed to the condition property
of the rule.

This commit improves this to handle parse errors:

- When libsinsp::filter::parser::parse() throws an exception, use
  get_pos() to get the position within the condition string.
- Add a new context() constructor that takes a filter pos_info instead
  of a YAML::Mark.

Now that positions aren't always related to the location of yaml
nodes, Make up a generic "position" struct for locations and convert
YAML::Mark and parser positions to a position struct.

Also allow a context to contain an alternate content string which is
used to build the snippet. For contexts related to condition strings,
the content is the condition.

c5442ccb41 new(userspace/falco): introduce new refactored stats writer class
This new model uses an async worker and a concurrent queue to handle
stats writing. This ensures better performance, because the live event
processing loop will just need to do a push on the queue instead of writing
to a file (only when the timer triggers), and should be thread-safe by design.

3c7b6e037a Falco engine changes to support multiple files in rule load results
The methods that throw exceptions from stringified results need to
additionally pass a rules_contents_t struct. This also meant that they
need to call the filename + content version of load_rules.

To avoid some duplicate code between the two load_rules_file methods,
move the work of opening the file into a private method
read_file(). It can throw an exception, which is passed through for
the void return method and caught + converted into a load_result error
for the method that returns a load_result.

Also, to avoid duplicate code between the void load_rules and
load_rules_file methods, add a private method interpret_load_result()
which throws an exception if the result has an error and prints
warnings otherwise if verbose is true.

49b7f0474f Falco application changes to support multiple files in rules results
Application changes to support multiple files when stringifying rules
results:

- In both validate_rules_files and load_rules_files, instead of
  loading each file individually and then calling load_rules(), add a
  separate step that loads all the files at once. The actual rules
  content strings are held in a vector. The map from filename to
  content (reference) points to entries in that vector.

- Both actions do the same work for this step, so put the
  implementation in a shared application template method read_files
  that works on iterators. It uses itertors because the load filenames
  are a list and the validate filenames are a vector.

98c1e3d3f1 Restructure rules result to properly support multiple files
The old version of rules_result assumed that all errors/warnings were
related to a single file. That was generally correct for errors, as
rules parsing always stopped at the first error, so there is only one
relevant file.

However, for warnings that was not the case. When reading multiple
files A and B, you might get a warning from file A *only* after
reading file B. For example, B might redefine a rule in such a way
that you could get unused list/macro warnings from file A.

To properly address this, make some changes to how contexts are
managed:

- Instead of creating snippets at the time the error/warning was
  generated, create snippets at the time the error/warning is
  converted into a string. This requires passing all rules contents to
  as_string()/as_json(), so define a
  falco::load_result::rules_contents_t map from filename to rules
  content (reference) and pass it in as_string/as_json(). Snippets are
  now generated from the rules content matching the filename in the
  context.
- When creating warnings/errors, there's no need to pass along the
  rules content. This is only used when converting an error into a
  string/json.

Also change snippet() to handle potentially very long lines. Instead
of always printing the entire line matching a location, print up to
snippet_width(param, with default 160 chars)/2 characters surrounding
the column from the location.

fefd23f2f1 fix: print full rule load errors without verbose/-v
The latest released falco always prints full details on errors when
used with -r (read rules)/-V (validate rules). However #2098 changed
this to only print full details when verbose is true.

Fix the regression by always printing errors when loading
rules. Warnings will be printed only with -v.

a37e2252b2 Update tests to use result struct + json-based validation
Update tests that validated rules files (typically looking for
errors/warnings) to use the new result struct + json based validation:

- When validating rules files, always use json output.

- In test cases, instead of parsing stderr/stdout, use new test
  properties "validate_ok", "validate_errors",
  "validate_warnings". These parse the json output and look for
  specific tuples of (error code, error message, item type, item name)
  in the output.

- There were a few tests that were actually validation tests but using
  the -r argument to load rules. Convert them to validation tests. In
  one case, split the test into two separate tests--one for
  validation, one ensuring that the rule doesn't match anything.

- There were a couple of tests that were duplicates of existing
  validation tests, just checking for the error in a different
  way. Remove them.

550cdbd176 Falco application changes to support rule loading result struct
Update the load_rules_files and validate_rules_files actions to use
the new falco_engine methods that return a rules result struct. The
app action interface is the same, returning ::fatal on error,
ok()/exit() otherwise. The difference is how any warnings/errors are
obtained--from the struct instead of an exception.

f7f6d72ac0 Rule loader changes to support result objects
Changes to the rule loader to support result objects:

- Instead of throwing falco_exception on internal error, throw a
  rule_load_exception instead, which contains distinct
  error/message/context information.

- A context object contains a chain of location structs chaining from
  the document root to the object where the error occurred. Each
  location has a file position (as a YAML::Mark), an item
  type (e.g. "rule", "list", "exception"), and an item name (e.g. "Write
  Below Etc"). This will allow showing the exact location of an
  error (e.g. list item/exception field) while also remembering the item
  that contained it.

- All the _info structs now contain a context so errors that occur
  after yaml parsing can still point to the original location in the
  yaml file.

- rule_loader::result is an implementation of the abstract class
  defined in falco_load_result. The implementation keeps track of a
  list of errors/warnigns that used to be in the configuration object,

- Clean up compile_ methods to just throw rule_load_exceptions or
  return nothing, and ensure that all rule_load_exceptions are caught in
  compile(). When caught, errors are added to the result object.

cbe7cceb87 Modify rule reader to use a result struct
Modify rule reader to use a result struct for errors and warnings:

- Instead of throwing a falco_exception to pass back errors, use a
  rule_load_exception, which contains distinct error codes, messages,
  and a context that points to the location of the error.

- The static method context_yaml_get_context() has moved to a method
  of the rule_loader context object + the result as_string() method.

- As objects are parsed, create relevant context objects as reading
  drills down into the contents of a rule/list/exception. This will
  enable for specific errors in, say, the middle of an exception/list
  while remembering the object that contains it.

- Modify decode_val()/decode_seq() to always return errors as
  exceptions. Previously, it was a mix of a bool return + some
  exceptions.

- decode_val()/decode_seq() are now more consistent about returning
  distinct errors for the property not existing, the property existing
  but not being a scalar/sequence value, and not being convertable to
  the templated value.

- Combine the two nearly identical decode_seq() functions into a
  single one that uses a lambda to perform the final step of adding to
  the vector/set.

- There are some item-specific decode_xxx functions for specific
  item properties like tags, exceptions fields/comps/values, etc.
  that call the above functions.

These changes simplify the calls to decode_seq()/decode_val() as they
don't need to add their own errors when returning false. Also some
calls weren't checking the return value.

bb44d992ab Change filter_warning_resolver to use warning codes
Now that we have a result struct and set of warning codes, change the
filter_warning_resolver to use them. This involves populating a set of
warning codes instead of strings.

Also, the methods to format warnings into human-readable strings is
now in the falco_load_result static methods, so move the text there

0066ba49ea Falco engine changes to support load_rules result class
Add new load_rules methods that return a result object instead of
throwing exceptions on error. The existing load_rules methods call the
new methods internally and continue to throw exceptions on
error/return individual values on success.

The result is returned as a unique_ptr so it can be populated while
loading rules (as a part of the configuration object) and then move()d
to the return value.

8497f25a43 Add a load result interface for use in new load_rules methods
Define a falco_load_result abstract class for use in new load_rules
methods. It's abstract so the implementation details in
rule_loader/rule_reader can be hidden from someone who wants to use
the API to load rules and work with a result.

The class defines a set of error codes/warning codes and has static
methods to get a short and long description of each error/warning.

There are virtual methods to access the important parts of a result:
 - successful or not
 - a string representation of the result, suitable for display to
   users. Takes a verbose argument. When verbose is true, the string is
   multi-line and has full details, including locations, item names,
   etc. When verbose is false, the string is single-line and just
   returns error codes.
 - a json representation of the result, suitable for automated
   parsing/interpretation later.

baf5540c30 Remove required_engine_version from falco engine load_rules APIs
The only use of it was to include in --support output, which is
redundant as the support output already includes the full contents of
each rules file.

Additionally, it wasn't even being updated after the switch from lua
rules loading to c++ rules
loading (https://github.com/falcosecurity/falco/pull/1966/ or
surrounding PRs).

This will simplify follow-on changes to add a real "result" to rules
loading methods, as there will be fewer API variants to support.

07b4d5a47a fix(rules): use exit event in reverse shell detection rule
In some cases the rule is not triggered when a reverse shell is spawned.
That's because in the rule we are checking that the file descriptor passed
as argument to the dup functions is of type socket and its fd number is "0, 1, or 2"
and the event direction is "enter".
The following event does not trigger the rule: dup2(socket_fd, STDIN_FILENO);
But using the exit event the rule is triggered.

bcda81f700 update(falco_scripts): Change Flatcar dynlinker path
The Flatcar kernel module build needs to relocate binaries in /host/lib/modules
to run with the host's ld and glibc. While testing with glibc 2.34 that we plan
to introduce soon, we found that the previous dynlinker symlink (ld-xxx.so)
doesn't exist any longer. Update the hostld variable to use a path that is
present in all versions of glibc.

85f91a3ec4 update(falco_scripts): support pre-built module/probe on Flatcar
Pre-built kernel modules/eBPF probes for Flatcar use the value of the OS
VERSION_ID field as KERNEL_RELEASE in the filename. A specific kernel release
version does not uniquely identify a Flatcar configuration, because Flatcar is
image-based instead of package-based. Here's a more specific example: the same
kernel version can be part of various Flatcar releases (across channels
alpha/beta/stable) with differences in configuration. This is why we use the
VERSION_ID value during offline builds with driverkit. Flatcar version numbers
are all higher than 1500.0.0, so there is no risk of collision with kernel
version numbers.

When locally building the kernel module on the system, we have access to the
correct kernel build directory at /lib/modules/$(uname -r)/build with the right
configuration and so for that branch, we need to reset KERNEL_RELEASE=$(uname -r).

See also the driverkit PR that introduces a builder for Flatcar:

6d56571e23 update(docker,falco_scripts): fix kernel module build on Flatcar
Relocate necessary tools from the kernel module build system to run using host
dynlinker and libraries, so that compiling falco module on Flatcar works.

Since Flatcar v2983.0.0, Flatcar ships with glibc-2.33, but the
falco-driver-loader container is based on debian:buster and so has a much older
glibc. This prevents some necessary tools within /lib/modules/*/build from
working which causes the falco module to fail to compile using dkms.

To make the tools work, we need to relocate them so we add patchelf to the
falco and local dockerfiles. The relocation is based on the approach done by
the sysdig agent-kmodule build system, but I'm unable to find the source code
for it. The host linker and libs will be found at /host/usr/lib64, so we change
the interpreter and rpath on the tools. The relocation happens on a copy of the
tools which are then bind mounted at the right location. The result allows the
module build to work.

a1bdf95a0f refactor(userspace/engine): improve ruleset interface definitions
The filter_ruleset interface its implementation evt_type_index_ruleset
have been modified as follows:
- Only keep track of ruleset ids and not names. The falco engine will take
care of mapping easy-to-remember ruleset names to ruleset ids.
To emphasize this, use ruleset_id everywhere and not ruleset.
Also, make it non-optional.
- Have explicit separate functions to enable/disable rules, instead of a single enable() method combined with a boolean flag.
This does *not* change the falco_engine interface, which has
similar methods, to avoid breaking API changes.

bbbdb311e0 refactor(userspace/engine): introduce interface for rulesets and their factory
This interface will allow us to use different ruleset implementations inside the same engine.
The goal is to define API boundaries that will allow swapping the current evttype-index
ruleset implementation more easily. Key benefits include: smaller component with less responsibilities,
easier substituibility, more testable design, opportunity to adopt different index strategies
depending on the ruleset implementation.

This means that when starting Falco passing to it a folder for its rules, it will properly manage
changes to any file inside the folders, plus any created/deleted file inside it.

Unified list of rules parsing, instead of having it done twice inside cmdline_options and configuration.
Instead, it is done only once, inside load_rules_files.

b89b3f82ee Falco main changes for app actions
This involves moving the code in falco_init() into individual files
below app_actions/. falco_init() simply calls app.run() now. When
app.run() returns false, print any erorr. When app.run() sets restart
to true, falco_init() is called again.

app.run() is still inside a catch block to catch any uncaught
exception.

1639e22462 Move most code from falco_init() to individual app actions
Each file below app_actions/ defines some of the methods declared in
falco::app::application.

Any state that needs to be shared betweeen methods, or between the run
and teardown methods, resides in falco::app::application::state(), so
the moved code stays pretty much as-is, other than replacing stack
variables with member variables in app_state.

9de80b7b92 Application changes to support actions
Changes to the falco::app::application object to support actions:

- All of the code that was in falco_init is now in methods of
  application. (A later commit actually moves the code from falco_init
  and into the split-up methods, this commit just declares them).
- Methods return an application::run_result object, which is a tuple
  of success/errstr/proceed. proceed=false is used to short circuit
  calling methods (think --help, --list, --support, etc.)
- application now has a run() method which runs the methods in an order
  that honors any implicit dependencies (e.g. you have to init an
  inspector before you open it, you have to do almost everything else
  before processing events, etc.)
- There are a few methods devoted to teardown, they are always called
  after the group of run methods are called.
- State that needs to be saved between methods, or saved between the
  run and teardown functions, is in a
  falco::app::application::state object.

0a51f4f1f1 Convert direct pointer refs to shared_ptr
Some objects used by falco (falco outputs, falco_formats, etc) were
using raw pointer references, which isn't great.

So convert use of raw pointers (originally passed from falco_init or
functions it called) with shared_ptr, as they are now held in
application state.

531bc3eb5a Falco test changes (small output matches) for actions
With the split of falco_init into application:: methods, including a
notion of a success/error/proceed result, there is a
more concrete line between runtime errors (e.g. things that throw
exceptions) and errors returned by methods that run the application.

Some of the plugins tests were expecting errors to be returned by
exceptions (e.g. with a leading "Runtime error: and a trailing "
Exiting.").

Now, the errors are just returned directly in application::run(), so
drop the leading and trailing bits in expected test outputs.

e1a5427874 update(userspace): add method to clear rule loader state
Once all rule files have been loaded, and all the rules have been compiled into filters and inserted in the engine rulesets, the loader definitions are maintained in memory without really being used. This commit adds a convenience method to clear the loader state and free-up some memory when engine consumers do not require such information in memory anymore.

2c0e6d3b88 update(userspace/engine): introduce new rule_reader class
The rule_reader class is responsible of parsing the YAML ruleset text and of using the rule_loader
to store the new definition in the internal state. This is a first step towards separating the YAML
reading logic from the rule parsing one. Potentially, this will allow us to read rulesets from another
YAML library or from something different than YAML files too.

911bd16556 update(engine): create a lua helper for rule filter manipulation
The lua_filter_helper class is a simple Lua wrapper that can be used in the Lua rule loader to
parse/compile rule filters, and manipulate them to resolve/replace list and macro references.

3879a283bf refactor(engine): remove dependency from lua parser
The Lua parser grabbed from libs chisels is not used anymore, as the compilation logic happen inside the new

c5818e6273 new(engine): add rule filter macro-resolver
This is a first step towards porting the rule filter building logic that is currently implemented in Lua.
filter_macro_resolver uses the newly introduced AST constructs from libsinsp, and
allow manipulating filter ASTs to resolve/replace macro references. This is meant to be used
at boot time by the rule loader (which we still want to maintain implemented in Lua for now).

df219b5e1d New tests for rule + exception, macro with unknown source
Add new test cases for a rule with an unknown source *and* an
exception, and a macro with an unknown source.

The first results in a rule warning (and no error), and the second
prints an error and skips.

ad42baed7a Check for unknown sources earlier (to handle exceptions)
If a rule has an unknown source, *and* has exceptions, loading the
rule will result in an error and not skipping the rule. This is
because exceptions are also validated for unknown fields, and that
occurs before the current check for unknown sources.

The fix is to move the check for unknown sources as soon as the rules
object is read.

36acd6dfbf Add user_known_mount_in_privileged_containers
This adds a new macro `user_known_mount_in_privileged_containers` which
allows the easier user-defined exclusions for the "Mount Launched in
Privileged Container" rule.

This would be cleaner with the exclusions feature, but this feature
is not used in the default ruleset yet, if I understand correctly.

* [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.
* [Fairwinds](https://fairwinds.com/) - [Fairwinds Insights](https://fairwinds.com/insights), Kubernetes governance software, integrates Falco to offer a single pane of glass view into potential security incidents. Insights adds out-of-the-box integrations and rules filter to reduce alert fatigue and improve security response. The platform adds security prevention, detection, and response capabilities to your existing Kubernetes infrastructure. Security and DevOps teams benefit from a centralized view of container security vulnerability scanning and runtime container security.
* [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.
* [gVisor](https://gvisor.dev/) - gVisor secures Kubernetes, containers, and workloads via an alternate execution environment that handles system calls in user space, blocking security issues before they reach the underlying host. gVisor provides defense-in-depth, protection against untrusted code execution, and a secure-by-default Kubernetes experience where containers are a security boundary. Falco can be used with gVisor to detect unusual or suspicious activity using its threat detection engine on top of gVisor runtime execution information.
* [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 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.
* [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.

* [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).

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.

* [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 driver. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended Falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-defined infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
* [Xenit AB](https://xenit.se/contact/) Xenit is a growth company with services within cloud and digital transformation. We provide an open-source Kubernetes framework that we leverage to help our customers get their applications to production as quickly and as securely as possible. We use Falco's detection capabilities to identify anomalous behaviour within our clusters in both Azure and AWS.
## 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.
* [StackRox](https://stackrox.io) is the industrys first Kubernetes-native security platform enabling organizations to build, deploy, and run cloud-native applications securely.

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 makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack.
Falco can also be extended to other data sources by using plugins.
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 Release Process
Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
## Overview
This document provides the process to create a new Falco release. In addition, it provides information about the versioning of the Falco components. At a high level each Falco release consists of the following main components:
- Falco binary (userspace)
- Falco kernel driver object files (kernel space)
- Option 1: Kernel module (`.ko` files)
- Option 2: eBPF (`.o` files)
- Falco config and primary rules `.yaml` files (userspace)
- Falco plugins (userspace - optional)
One nice trait about releasing separate artifacts for userspace and kernel space is that Falco is amenable to supporting a large array of environments, that is, multiple kernel versions, distros and architectures (see `libs` [driver - kernel version support matrix](https://github.com/falcosecurity/libs#drivers-officially-supported-architectures)). The Falco project manages the release of both the Falco userspace binary and pre-compiled Falco kernel drivers for the most popular kernel versions and distros. The build and publish process is managed by the [test-infra](https://github.com/falcosecurity/test-infra) repo. The Falco userspace executable includes bundled dependencies, so that it can be run from anywhere.
The Falco project also publishes all sources for each component. In fact, sources are included in the Falco release in the same way as some plugins (k8saudit and cloudtrail) as well as the rules that are shipped together with Falco. This empowers the end user to audit the integrity of the project as well as build kernel drivers for custom kernels or not officially supported kernels / distros (see [driverkit](https://github.com/falcosecurity/driverkit) for more information). While the Falco project is deeply embedded into an ecosystem of supporting [Falco sub-projects](https://github.com/falcosecurity/evolution) that aim to make the deployment of Falco easy, user-friendly, extendible and cloud-native, core Falco is split across two repos, [falco](https://github.com/falcosecurity/falco) (this repo) and [libs](https://github.com/falcosecurity/libs). The `libs` repo contains >90% of Falco's core features and is the home of each of the kernel drivers and engines. More details are provided in the [Falco Components Versioning](#falco-components-versioning) section.
Finally, the release process follows a transparent process described in more detail in the following sections and the official [Falco docs](https://falco.org/) contain rich information around building, installing and using Falco.
### Falco Binaries, Rules and Sources Artifacts - Quick Links
The Falco project publishes all sources and the Falco userspace binaries as GitHub releases. Rules are also released in the GitHub tree Falco release tag.
- [Falco Releases](https://github.com/falcosecurity/falco/releases)
- `tgz`, `rpm` and `deb` Falco binary packages (contains sources, including driver sources, Falco rules as well as k8saudit and cloudtrail plugins)
- `tgz`, `zip` source code
- [Libs Releases](https://github.com/falcosecurity/libs/releases)
- `tgz`, `zip` source code
- Falco Rules (GitHub tree approach)
- RELEASE="x.y.z", `https://github.com/falcosecurity/falco/tree/${RELEASE}/rules`
Alternatively Falco binaries or plugins can be downloaded from the Falco Artifacts repo.
- [Falco Artifacts Repo Packages Root](https://download.falco.org/?prefix=packages/)
- [Falco Artifacts Repo Plugins Root](https://download.falco.org/?prefix=plugins/)
### Falco Drivers Artifacts Repo - Quick Links
The Falco project publishes all drivers for each release for all popular kernel versions / distros and `x86_64` and `aarch64` architectures to the Falco project managed Artifacts repo. The Artifacts repo follows standard directory level conventions. The respective driver object file is prefixed by distro and named / versioned by kernel release - `$(uname -r)`. Pre-compiled drivers are released with a [best effort](https://github.com/falcosecurity/falco/blob/master/proposals/20200818-artifacts-storage.md#notice) notice. This is because gcc (`kmod`) and clang (`bpf`) compilers or for example the eBPF verifier are not perfect. More details around driver versioning and driver compatibility are provided in the [Falco Components Versioning](#falco-components-versioning) section. Short preview: If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with.
- [Falco Artifacts Repo Drivers Root](https://download.falco.org/?prefix=driver/)
- Option 1: Kernel module (`.ko` files) - all under same driver version directory
- Option 2: eBPF (`.o` files) - all under same driver version directory
### Timeline
Falco releases are due to happen 3 times per year. Our current schedule sees a new release by the end of January, May, and September each year. Hotfix releases can happen whenever it's needed.
Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
### Procedures
The release process is mostly automated requiring only a few manual steps to initiate and complete it.
Moreover, we need to assign owners for each release (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community).
At a high level each Falco release needs to follow a pre-determined sequencing of releases and build order:
- [1 - 3] `libs` (+ `driver`) and `plugins` components releases
- [4] Falco driver pre-compiled object files push to Falco's Artifacts repo
- [5] Falco userspace binary + rules release
Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
## 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.
Prior to cutting a release the following preparatory steps should take 5 minutes using the GitHub UI.

## Falco Components Versioning
This section provides more details around the versioning of all components that make up core Falco. It can also be a useful guide for the uninitiated to be more informed about Falco's source. Because the `libs` repo contains >90% of Falco's core features and is the home of each of the kernel drivers and engines, the [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) is an excellent additional resource. In addition, the [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) provides similar details around Falco's plugins. `SHA256` checksums are provided throughout Falco's source code to empower the end user to perform integrity checks. All Falco releases also contain the sources as part of the packages.
### Falco repo (this repo)
- Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax or `falco --list -N | sha256sum` has changed. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The primary idea behind the hash is that when new filter / display fields (see currently supported [Falco fields](https://falco.org/docs/rules/supported-fields/)) are introduced a version bump indicates that this field was not available in previous engine versions. In case a new Falco rule uses new fields, the [Falco rules](https://github.com/falcosecurity/falco/blob/master/rules/falco_rules.yaml) file needs to bump this version as well via setting `required_engine_version` to the new version.
- During development and release preparation, libs and driver reference commits are often bumped in Falco's cmake setup ([falcosecurity-libs cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/falcosecurity-libs.cmake#L30) and [driver cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/driver.cmake#L29)) in order to merge new Falco features. In practice they are mostly bumped at the same time referencing the same `libs` commit. However, for the official Falco build `FALCOSECURITY_LIBS_VERSION` flag that references the stable Libs version is used (read below).
- Similarly, Falco plugins versions are bumped in Falco's cmake setup ([plugins cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/plugins.cmake)) and those versions are the ones used for the Falco release.
- At release time Plugin, Libs and Driver versions are compatible with Falco.
- If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with (read more below under Libs).
```
Falco version: x.y.z (sem-ver like)
Libs version: x.y.z (sem-ver like)
Plugin API: x.y.z (sem-ver like)
Driver:
API version: x.y.z (sem-ver)
Schema version: x.y.z (sem-ver)
Default driver: x.y.z+driver (sem-ver like, indirectly encodes compatibility range in addition to default version Falco is shipped with)
```
### Libs repo
- Libs version is a git tag (`x.y.z`) and when building Falco the libs version is set via the `FALCOSECURITY_LIBS_VERSION` flag (see above).
- Driver version in and of itself is not directly tied to the Falco binary as opposed to the libs version being part of the source code used to compile Falco's userspace binary. This is because of the strict separation between userspace and kernel space artifacts, so things become a bit more interesting here. This is why the concept of a `Default driver` has been introduced to still implicitly declare the compatible driver versions. For example, if the default driver version is `2.0.0+driver`, Falco works with all driver versions >= 2.0.0 and < 3.0.0. This is a consequence of how the driver version is constructed starting from the `Driver API version` and `Driver Schema version`. Driver API and Schema versions are explained in the respective [libs driver doc](https://github.com/falcosecurity/libs/blob/master/driver/README.VERSION.md) -> Falco's `driver-loader` will always fetch the default driver, therefore a Falco release is always "shipped" with the driver version corresponding to the default driver.
- See [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) for more information.
### Plugins repo
- Plugins version is a git tag (`x.y.z`)
- See [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) for more information.

### How does Falco work?
Falco traces kernel events and reports information about the system calls being executed at runtime.
Falco leverages the extended berkley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel.
Falco leverages the extended berkeley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel.
Falco enriches these kernel events with information about containers running on the system.
Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
At runtime, Falco will reason about these events and assert them against configured security rules.

# --- [Description]
#
# This is an index that controls the dimension of the syscall buffers.
# The syscall buffer is the shared space between Falco and its drivers where all the syscall events
# are stored.
# Falco uses a syscall buffer for every online CPU, and all these buffers share the same dimension.
# So this parameter allows you to control the size of all the buffers!
#
# --- [Usage]
#
# You can choose between different indexes: from `1` to `10` (`0` is reserved for future uses).
# Every index corresponds to a dimension in bytes:
#
# [(*), 1 MB, 2 MB, 4 MB, 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB, 512 MB]
# ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^
# | | | | | | | | | | |
# 0 1 2 3 4 5 6 7 8 9 10
#
# As you can see the `0` index is reserved, while the index `1` corresponds to
# `1 MB` and so on.
#
# These dimensions in bytes derive from the fact that the buffer size must be:
# (1) a power of 2.
# (2) a multiple of your system_page_dimension.
# (3) greater than `2 * (system_page_dimension)`.
#
# According to these constraints is possible that sometimes you cannot use all the indexes, let's consider an
# example to better understand it:
# If you have a `page_size` of 1 MB the first available buffer size is 4 MB because 2 MB is exactly
# `2 * (system_page_size)` -> `2 * 1 MB`, but this is not enough we need more than `2 * (system_page_size)`!
# So from this example is clear that if you have a page size of 1 MB the first index that you can use is `3`.
#
# Please note: this is a very extreme case just to let you understand the mechanism, usually the page size is something
# like 4 KB so you have no problem at all and you can use all the indexes (from `1` to `10`).
#
# To check your system page size use the Falco `--page-size` command line option. The output on a system with a page
# size of 4096 Bytes (4 KB) should be the following:
#
# "Your system page size is: 4096 bytes."
#
# --- [Suggestions]
#
# Before the introduction of this param the buffer size was fixed to 8 MB (so index `4`, as you can see
# in the default value below).
# You can increase the buffer size when you face syscall drops. A size of 16 MB (so index `5`) can reduce
# syscall drops in production-heavy systems without noticeable impact. Very large buffers however could
# slow down the entire machine.
# On the other side you can try to reduce the buffer size to speed up the system, but this could
# increase the number of syscall drops!
# As a final remark consider that the buffer size is mapped twice in the process' virtual memory so a buffer of 8 MB
# will result in a 16 MB area in the process virtual memory.
# Please pay attention when you use this parameter and change it only if the default size doesn't fit your use case.

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 manageable.
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.
