Selecting the right eBPF toolchain requires matching your workload to the appropriate program type and library, such as libbpf for C, ebpf-go for Go, or bpftrace for tracing. The decision depends on your language ecosystem and specific performance requirements.

The eBPF verifier rejects programs that violate safety constraints, such as invalid memory access or unbounded loops. Debugging verifier rejections involves triaging the specific verifier logs, checking kernel-version constraints, and applying safe production-ready patterns to resolve the flagged issues.

The best way to design eBPF maps for production applications is to select the correct map type for your data sharing needs while enforcing safe defaults. Proper map design addresses kernel version compatibility and ensures the verifier accepts your memory access patterns.

Yes, you can use ebpf-go to build and load eBPF programs in production. The toolchain supports production-ready patterns, but you must carefully address kernel-version constraints and verifier considerations to ensure safe and stable operation.

Kernel version constraints directly affect your eBPF program types by limiting the available hooks, map types, and verifier features. You must check your target kernel version to ensure your selected program types and workflows are supported before deployment.

Common eBPF verifier limitations include strict bounds checking and restrictions on unbounded loops. You should avoid using bpftrace for complex production logic that requires persistent state or custom map designs, as it is optimized for quick tracing rather than robust program deployment.
