* irmd: Reject client encap without configured KEXDimitri Staessens36 hours2-0/+51
| | | | | | | | | | | | | A client asking for client-side encapsulation against a server that has no kex= configured left scfg->x.str NULL, crashing the handshake inside strstr(). Client encapsulation decapsulates with the server's configured static key, so a server without the configured key exchange cannot serve the request.

* ipcpd: Assign random MAC on ETH poa with loopbackDimitri Staessens36 hours1-0/+24
| | | | | | | | | | | | | | | The loopback has an all-zero MAC, so two PoAs on a loopback receive their own frames and a PoA refuses its own FLOW_REQ, failing the flow with ECONNREFUSED. The shim IPCP didn't have this problem because it ignored requests for names not registered locally (shim-data). The PoA has no "local" name registry, it uses the unicast IPCP's directory (DHT) via IRMd query requests. This fixes the issue by generating a random locally administered MAC on the loopback device.

* ipcpd: Use capacity queue estimation for mb-ecnDimitri Staessens36 hours24-1078/+3523
| | | | | | | | | | | The mb-ecn algorithm was using rbuff queue depths in packets to mark, but sockets in the poa component report capacity in bytes. The tx rings are now adaptive to block on queuing delay instead of when full to prevent buffer bloat, controllable via fccntl (FLOWSTXQDLY and FLOWGTXQDLY).

* lib: Replace shim IPCPs with points of attachmentDimitri Staessens36 hours68-5524/+9712
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ipcpd: Add flow overshoot protection to mb-ecnDimitri Staessens2026-07-2214-80/+873
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ECN marks were the only source of congestion information, and going into congestion collapse (dropping a lot of ECN packets and causing loss of signal) was unrecoverable. The sender's slow-start ramp clock now tracks a measured RTT to avoid overshooting into congestion collapse on the previously fixed (14ms) doubling on long-delay (e.g. 100ms) links. The flow allocator now carries a periodic heartbeat/ack to keep RTT estimates up-to-date. The heartbeat also serves as a congestion collapse detector: consecutive heartbeat losses will go into loss recovery, halving the window and pausing Additive Increase until the path is clear. The DT component now has a max_rtt config parameter that serves as a hint for the layer RTT to optimize slow-start for low-latency networks. These two mechanisms follow TCP, however only during slow start up to the first ECN signal and to recover from a total collapse until the ECN signal returns. MB-ECN is still fully RTT-independent in the AI/PD region. A shorter RTT path will just reach its equal fair share faster than a longer RTT path.

* ipcpd: Add congestion avoidance unit testsDimitri Staessens2026-07-196-0/+3653
| | | | | | | | | | | | | | | | | | | | | | | | | Cover the shared per-aggregate contexts, the mb-ecn policy and the link capacity estimator. The controller tests pin the invariants of the algorithm: the first mark is reported immediately, the receiver's congestion mean is independent of packet rate and its window adapts to hold a fixed sample count, increase and decrease are invariant under control cadence, a starved sender still cuts and later recovers, signals age out on rate-relative horizons, capacity feedback derives the rate floor and recovery slope with clamps and a staleness fallback, and the pacer bounds the burst after idle. The estimator tests drive synthetic arrival traces: the capacity code survives a round trip within its resolution, hops combine by MIN, busy-period drain measures the link rate, windows extend on slow links, sparse idle observations are tolerated where unsaturated windows are rejected, shaped links measure at the shaped rate, stale windows are discarded, and windows bordering an empty queue can only lower the estimate.

* ipcpd: Rework congestion avoidanceDimitri Staessens2026-07-1920-311/+1539
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Congestion avoidance is a property of the layer, orthogonal to ARQ and to flow control: FRCP retransmits and lets the peer pace the sender, per flow, end-to-end; the IPCP paces path aggregates. Each signal means one thing: a loss triggers a retransmission, a mark means congestion, the peer window means a slow receiver. Every flow is paced by the same rate law whatever its QoS, so a greedy raw sender shares a bottleneck fairly with a reliable stream. The unit of control is the (destination address, QoS cube) aggregate: all flows toward that destination share one controller and one rate; a start-time fair-queuing pacer divides the rate across them by deadline instead of blocking the send path, and a new flow rides the aggregate's estimates at its current rate, with no probing of its own. Slow start runs once per aggregate. The congestion signal is a multi-bit magnitude: forwarders mark packets with their standing queue depth, MAX-combined across hops, so a packet carries the deepest queue on its path. The receiver feeds back a time-integral mean over a window that adapts to the flow's byte rate, measuring a slow flow with the same fidelity as a fast one. The sender runs AIMD scaled by elapsed wall-clock time, which makes the steady-state allocation RTT-independent. The PCI gains one byte: the path capacity as a quarter-log2 code. Forwarders estimate their egress rate from busy-period drain and MIN-stamp the byte, the receiver returns the window minimum with its feedback, and the sender scales its rate floor and additive slope to the bottleneck (C / 32). A deep cut implies a backlogged bottleneck and a backlogged bottleneck advertises its capacity, so the scaled floor is live exactly when recovery needs it: the probe heals a halving in seconds at any link rate, and the floor bounds the deepest hole to a factor 32 below the bottleneck.
