Document the required glibc version for wide compatibilty
What to document
Plugins authors must build their plugins using the same glibs version we use in Falco. We have to document that.
/cc @jasondellaluce
Thanks! FYI, I use the following Dockerfile to ensure that I have the same glibc as the one in Falco:
# Use the same base image as falco to ensure compatibility with glibc version
FROM golang:buster as builder
# Cache go modules so they won't be downloaded at each build
COPY go.mod go.sum /src/
RUN cd /src && go mod download
COPY ./ /src
RUN cd /src && make -C falco-plugin
# Use the following command to get the built files:
# DOCKER_BUILDKIT=1 docker build -f falco-plugin/Dockerfile --output=falco-plugin/ .
FROM scratch AS deploy-source
COPY --from=builder /src/falco-plugin/*.so /
Btw, to build and publish our plugins, we currently use this :point_down: https://github.com/falcosecurity/test-infra/blob/master/images/build-plugins/Dockerfile#L6

For the record, recently we upgraded golang in our CI, and broke the glibc compatibility.
@LucaGuerra and I are investigating.
For the record, recently we upgraded golang in our CI, and broke the glibc compatibility.
@LucaGuerra and I are investigating.
Fix: https://github.com/falcosecurity/plugins/pull/497/files
Update (as discussed with @LucaGuerra):
At the time of writing, Falco requires GLIBC 2.17 or newer (this is, however, not officially documented yet)
For plugins shipped with this repository, based on the current CI builder (using the golang:1.22-bullseye image :point_down: ) the minimum guaranteed compatibility is with GLIBC 2.31. However, most plugins need a reduced set of GLIBC symbols and are usually compatible with older versions of GLIBC.
