Remove CAP_NET_ADMIN requirement and eliminate need for CAP_SYS_ADMIN on
modern kernels by using non-promiscuous mode for packet capture. This
significantly reduces security surface by following principle of least privilege.
Make eBPF the default build configuration on Linux for better
performance and lower overhead process identification.
Changes:
- Set default features to include ebpf in Cargo.toml
- Remove explicit --features linux-default from build configs
- Update all documentation to reflect eBPF is now default
- Add instructions for building without eBPF (--no-default-features)
eBPF automatically falls back to procfs if it fails to load.
Closes#32
The procfs-based process lookup was triggering a full scan on every cache
miss instead of relying on periodic refresh. This caused 50+ full procfs
scans per enrichment cycle when multiple connections lacked process info.
Changed get_process_for_connection() to do simple cache lookups only.
Periodic refresh (every 5s) is already handled by the enrichment thread.
Also added PROFILING.md with flamegraph profiling guide.
Split large README.md (1101 lines) into separate documentation files
for better organization and maintainability:
- README.md: condensed to 233 lines with quick start and overview
- INSTALL.md: complete installation guide and permissions setup
- USAGE.md: detailed usage guide with filtering and sorting
- ARCHITECTURE.md: technical details and platform implementations
- EBPF_BUILD.md: updated references to new INSTALL.md structure
Added collapsible sections in README for optional details and
included "Documentation Moved" section for backward compatibility
with external links.
- Add Windows process lookup using GetExtendedTcpTable/GetExtendedUdpTable
- Resolve process names via OpenProcess and QueryFullProcessImageNameW
- Support TCP/UDP IPv4 and IPv6 connections
- Implement time-based caching with 2-second TTL
- Fix port byte order conversion from network to host order
- Migrate from winapi to windows crate (v0.59)
- Add debug logging for process lookup operations
- Update documentation in ROADMAP.md and README.md
Closes#36
* feat: detect insufficient privileges before network interface access
- Add privilege detection module for Linux, macOS, and Windows
- Check privileges before TUI initialization for visible errors
- Provide platform-specific instructions (sudo, setcap, Docker flags)
- Detect container environments and provide Docker-specific guidance
* Remove musl targets to simplify Linux builds and fix cross-compilation issues
* Enable eBPF by default on Linux via linux-default feature for better packet capture
* Add macOS code signing and notarization support with graceful fallback for unsigned builds
* Fix Windows MSI packaging with improved WiX configuration and Npcap library linking
* Auto-extract changelog content from CHANGELOG.md into GitHub release notes
* Fix ARM cross-compilation (aarch64, armv7) with proper library paths and eBPF support
* Add comprehensive installation documentation for DMG, MSI, DEB, and RPM packages
* Allow re-running releases with --clobber flag for artifact uploads
* feat: Add experimental eBPF support for enhanced socket tracking
- Implement eBPF-based socket tracker for Linux with CO-RE support
- Add minimal vmlinux header (5.5KB) instead of full 3.4MB file
- Create graceful fallback mechanism to procfs when eBPF unavailable
- Add comprehensive eBPF build documentation
- Integrate libbpf-rs for eBPF program loading and management
- Support both IPv4 and IPv6 socket tracking
- Add capability checking for required permissions
The eBPF feature is optional and disabled by default. When enabled,
it provides faster and more accurate process-to-socket mapping on
Linux systems with appropriate permissions.
