* lib: Replace shim IPCPs with points of attachmentDimitri Staessens40 hours1-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removes the UDP and Ethernet shim IPCPs. The unicast and broadcast IPCPs can now directly attach to a "legacy" socket. We adopt Saltzer's Point-of-Attachment terminology, also advocated in Day's "Patterns in Network Architecture". The "poa" component manages these PoA's with one management thread, one link monitoring thread and one thread per attached point. For Ethernet PoA's the irm connect and enroll can resolve the destination IPCP or Layer name with a broadcast name query over the attached PoAs (first reply wins). UDP PoA's require a destination IP address or FQDN. attach to a local endpoint (required both server and client side): irm ipcp poa attach name a udp 10.0.0.1 irm ipcp poa attach name a udp 10.0.0.1:3435 irm ipcp poa attach name a udp [::1]:3435 irm ipcp poa attach name a eth dev eth0 irm ipcp poa attach name a eth dev eth0 ethertype 0xA000 release a PoA (refused while it carries a flow): irm ipcp poa detach name a udp 10.0.0.1:3435 irm ipcp poa detach name a eth eth0 list an IPCP's PoAs: irm ipcp poa list name a connect to a peer, by name or at an address: irm ipcp connect name b dst a irm ipcp connect name b dst a eth irm ipcp connect name b dst a eth dev eth0 irm ipcp connect name b dst a udp 10.0.0.1:3435 irm ipcp connect name b dst a udp peer.example.com:3435 disconnect by peer name, no address: irm ipcp disconnect name b dst a irm ipcp disconnect name b dst a component mgmt enroll has the same shape as connect: irm ipcp enroll name b layer lr autobind irm ipcp enroll name b layer lr autobind eth dev eth0 irm ipcp enroll name b layer lr autobind udp 10.0.0.1:3435 the IRMd config file attaches PoAs and names peers the same way: udp = [ "10.0.0.1", "10.0.0.1:3436" ] eth = [ "eth0", {dev="eth1", ethertype=0xA007} ] enrol={dst="LAN", eth={dev="eth0"}} conn=[{dst="lan3", eth={}}, {dst="lan4", udp="10.0.0.1:3435"}] Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
* build: Refactor CMake back to in-tree CMakeListsDimitri Staessens2026-02-131-0/+18
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.
