v0.36.0

Released on 2023-09-26

Breaking Changes :warning:

  • The default rules file that is shipped in the Falco image and/or can be downloaded via falcoctl as falco-rules is now a stable rule file. This file contains a much smaller number of rules that are less noisy and have been vetted by the community. This serves as a much requested "starter" Falco rule set that covers many common use case. The rest of that file has been expanded and split into falco-incubating-rules and falco-sandbox-rules. For more information, see the rules repository
  • The main falcosecurity/falco container image and its falco-driver-loader counterpart have been upgraded. Now they are able to compile the kernel module or classic eBPF probe for relatively newer version of the kernel (5.x and above) while we no longer ship toolchains to compile the kernel module for older versions in the default images. Downloading of prebuilt drivers and the modern eBPF will work exactly like before. The older image, meant for compatibility with older kernels (4.x and below), is currently retained as falcosecurity/falco-driver-loader-legacy.
  • The Falco HTTP output no longer logs to stdout by default for performance reasons. You can set stdout logging preferences and restore the previous behavior with the configuration option http_output.echo in falco.yaml.
  • The --list-syscall-events command line option has been replaced by --list-events which prints all supported system events (syscall, tracepoints, metaevents, internal plugin events) in addition to extra information about flags.
  • The semantics of proc.exepath have changed. Now that field contains the executable path on disk even if the binary was launched from a symbolic link.
  • The -d daemonize option has been removed.
  • The -p option is now changed:
    • when only -pc is set Falco will print container_id=%container.id container_image=%container.image.repository container_image_tag=%container.image.tag container_name=%container.name
    • when -pk is set it will print as above, but with k8s_ns=%k8s.ns.name k8s_pod_name=%k8s.pod.name appended
