@alban Please give https://github.com/cilium/ebpf/pull/1590 a try instead. `KernelModuleTypes` is kind of bolted on as it is and I'd rather not touch it unless it's for refactoring, e.g. moving more of...

Superseded by https://github.com/cilium/ebpf/pull/1590.

`cilium-agent level=fatal msg="Unable to initialize service maps" error="Unable to create map /sys/fs/bpf/tc/globals/cilium_lb4_reverse_sk: cannot allocate memory" subsys=daemon` This likely means the Cilium pods are running out of memory on those nodes....

@aanm Shouldn't this issue be in the cilium-cli repo? I'm seeing a few issues specific to cilium-cli here and I'm not sure where to route them.

Sorry, this situation is unlikely to change until we drop support for pre-5.0 kernels. If there are any other ideas aside from uname parsing, I'm all ears. Closing for now.

I'd like to get this behaviour back in some form. To me, it's rather surprising that no lines are emitted until `go test` has returned. Travis CI kills jobs that...

@rgo3 I've added some notes at https://github.com/cilium/cilium/issues/41746#issuecomment-3607619465. This became a bit simpler in that we don't want to use spew but write out our own machine-readable format (json for now)...

@liuchangyan Have you considered using a bpf ringbuf instead of a perf event map? It's much less complicated to consume from user space since there's only 1 ring, which also...

@xmulligan Good catch, we can change the heading to ### [ebpf-go-reviewers](https://github.com/orgs/cilium/teams/ebpf-go-reviewers/members) and [ebpf-go-windows-reviewers](https://github.com/orgs/cilium/teams/ebpf-go-windows-reviewers/members)
