Can you describe some of those bugs? What helpers were you using? I've been doing bonkers stuff with eBPF for the last year and, while I've definitely had bugs, none of them took my kernel down.

I no longer have access to the code, and the kernel has since been patched. Mostly doing some observability around new network connections.

We definitely hit this one at some point: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1763454

We also ran into a couple of similar but unrelated panic bugs on much newer kernels on non-Ubuntu distros.
