irmd: Allow direct rbuff between local processes

2026-02-22T15:02:16+00:00

This allows bypassing the IPCP for local processes that share the same packet pool, lowering latency between processes to comparable levels as Unix sockets (RTT in the order of a microsecond). For local processes, no IPCPs are needed: $ irm b prog oping n oping $ oping -l Ouroboros ping server started. New flow 64. Received 64 bytes on fd 64. The direct IPC can be disabled with the DISABLE_DIRECT_IPC build flag. Note that this is needed for rumba 'local' experiments to emulate network topologies. Without this flag all processes will just communicate directly. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Refactor CMake back to in-tree CMakeLists

2026-02-13T08:22:29+00:00

This moves the build definitions back to src/ subdirectories (CMakeLists.txt per component). Configuration and dependencies are kept out of tree. Configuration options are bundled into cmake/config/ modules. Dependencies are grouped by component (system/, crypt/, eth/, coverage/, etc.). It now consistently uses target-based commands (target_include_directories, target_link_libraries) instead of global include_directories(). Proper PRIVATE/PUBLIC visibility for executable link libraries. CONFIG_OUROBOROS_DEBUG now properly set based on being a valid debug config (not just checking the string name). It also adds OuroborosTargets export for find_package() support and CMake package config files (OuroborosConfig.cmake) for easier integration with CMake projects. The build logic now follows more idiomatic CMake practices with configuration separated from target definitions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
