Release-v1.1.0

Highlights

This is the first stable release of eBPF for Windows following the v1.0.0 release candidates. The important changes include:

• Custom Maps: eBPF extensions can now register and implement their own custom map types via custom map types via ebpf_base_map_provider_dispatch_table_t, enabling extension-specific map entry handling.
• Synchronous Ring Buffer and Perf Event Array APIs: Implements libbpf-compatible synchronous APIs for both ring buffer (ring_buffer__poll, ring_buffer__consume) and perf event array (perf_buffer__poll, perf_buffer__consume) maps.
• Accept and Bind Hook Hard/Soft Permit: Accept and bind hooks now support hard and soft permit verdicts (extending connect hook support from v1.0), giving control over whether subsequent hook programs/filters can override a permit decision.
• Epoch Memory Improvements: Replaced InterlockedCompareExchange64 with ReadAcquire64 for published epoch reads, eliminating LOCK-prefix cache-line contention (4–43% benchmark improvement). Also fixed a per-CPU epoch skew bug and wrapped remaining async completion code paths in epoch logic.

Full Changelog: Release-v1.0.0-rc1...Release-v1.0.0-rc2

v1.0.0-rc1

Highlights

This is the release-candidate for v1.0 of eBPF for Windows. The important changes include:

• Proof of Verification: This feature enforces that only those native eBPF programs are loaded, that are packaged in kernel drivers that are signed by a Microsoft issued certificate with the "eBPF verification" EKU. This certificate proves that the native program was generated from an input BPF program that passed verification and was converted using the bpf2c toolchain.
• Breaking changes in libbpf implementations: Changes in behavior in various libbpf functions including bpf_prog_attach, ring_buffer__new, perf_buffer__new and lifetime management functions for nested map types, to align closely with the Linux behavior.
