As it turns out, the flaky test was caused by a bug in the eBPF kernel where we read the old channel data header from the wrong offset. This made us essentially read garbage data for the channel number, causing us to: a. Compute a bad checksum b. Send the packet on a completely wrong channel The reason this caused a flaky test is that it requires on side to pick IPv4 to talk to the relay and the other side IPv6. The happy-eyeballs approach of the `allocation` module made that non-deterministic, only exposing this bug occasionally. To ensure these kind of things are detected earlier in the future, I am adding an additional CI step that checks all packets emitted by the eBPF kernel for checksum errors.

# The veth driver uses a pair of interfaces to connect the docker bridge to the container namespace.
|
|
# For containers that have an eBPF program attached and do XDP_TX, we need to attach a dummy program
|
|
# to the corresponding veth interface on the host to be able to receive the XDP_TX traffic and pass
|
|
# it up to the docker bridge successfully.
|
|
#
|
|
# The "recommended" way to do this is to set both veth interfaces' GRO to on, or attach an XDP program
|
|
# that does XDP_PASS to the host side veth interface. The GRO method is not reliable and was shown to
|
|
# only pass packets in large bursts every 15-20 seconds which breaks ICE setup, so we use the XDP method.
|
|
#
|
|
# For correct behaviour, we also disable any kind of offloading for all veth and bridge devices.
|
|
# This forces the kernel to calculate all checksums in software.
