Randomly corrupts packets by flipping bits, using Linux tc netem.

Target kind: Pod
Implementation: Daemon (ExecNetworkChaos with action: corrupt)
Rollback: Yes — removes tc netem rules

Name	Type	Required	Default	Description
percent	string	Yes	—	Percentage of packets to corrupt (0-100)

Example

apiVersion: chaos.chaosplane.io/v1alpha1
kind: ChaosExperiment
metadata:
  name: network-corrupt-example
  namespace: default
spec:
  target:
    kind: Pod
    namespace: default
    labelSelector:
      matchLabels:
        app: data-pipeline
  action:
    type: network-corrupt
    parameters:
      percent: "5"
  duration: 30s
  rollback:
    enabled: true

Rollback behavior

Removes the tc netem qdisc from the pod's network interface.

Implementation notes

Uses tc qdisc add dev eth0 root netem corrupt PERCENT%. Corrupted packets are detected by TCP/IP checksums and retransmitted. Tests checksum validation, error detection, and protocol resilience. Higher-level protocols (TLS, HTTP/2) may handle corruption differently than raw TCP.
