Another month has passed and Falco continues to grow!
Today we announce the release of Falco 0.22 🥳
You can take a look at the whole set of changes here:
In case you just want to try out the stable Falco 0.22, you can install its packages following the usual process outlined in the docs:
Do you rather prefer using the docker images? No problem!
docker pull falcosecurity/falco:0.22.1
docker pull falcosecurity/falco:0.22.1-minimal
docker pull falcosecurity/falco:0.22.1-slim
This release comes with a lot of fixes for longstanding tough bugs!
But also with some new features 😊
In case you are managing the Falco drivers yourself please make sure to update them to version a259b4bf49c3330d9ad6c3eed9eb1a31954259a6 (reference here).
Some users reported a problem in getting the eBPF driver to work on GKE.
This release finally introduces a fix for it.
Some users reported they were getting <NA> values for docker and Kubernetes metadata in the alerts.
With the following pull requests, falco#1133, falco#1138, and falco#1140, the problem should now be definitely fixed, as reported by the users testing the development release of Falco containing the fixes.
Going through the process of a better modularization for Falco, now the Falco version and the version of its drivers are two distinct things finally!
Clearly, in order to obtain this some PRs were needed 😝 both in the packagin system and in the falco-driver-loader script.
This release also had a lot of rule changes. Most notably vicenteherrera created many new rules:
Thanks Vicente! 🙌🏻
Thanks to PR falco#1099 users can now disable the asynchronous fetching of CRI metadata forcing it to be synchronous.
To do it, just pass the --disable-cri-async flag to Falco.
While this can slow down Falco event processing and can cause drop rate to raise, it helps in getting less null values for containers metadata.
Before using this flag, please try out this release since it contains other fixes for this topic!
23 pull requests merged in, 18 of which containing changes directly targeting our end-users.
49 commits since past release, in 30 days.
The drivers build grid is almost ready.
Just some missing refinements and then Falco will have again a set of prebuilt drivers (both kernel modules and eBPF probes) to be downloaded during the installation!
