## Common questions

### What troubleshooting topics are covered in the project documentation?

The troubleshooting guide covers installation failures, runtime errors, performance problems, and cleanup procedures.

### Does the TCP/IP bypass require changes to the Linux kernel?

No, the solution is described as independent and does not require changes to the Linux kernel.

### Which Istio pod-to-pod communication scenarios are targeted?

It targets pod-to-pod communication both with sidecar injection and without sidecar injection.

### What caveat is noted when ensuring TCP traffic is proxied by the Envoy sidecar?

Istio cannot guarantee that traffic will not bypass the proxy.
