* lib: Update FRCP implementationDimitri Staessens4 days1-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Flow and Retransmission Control Protocol (FRCP) runs end-to-end between two peers over a flow. It provides reliability, in-order delivery, flow control, and liveness. Note that congestion avoidance is orthogonal to FRCP and handled in the IPCP. A fixed 16-octet header, network byte order, is prefixed to every FRCP packet: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | flags | hcs | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | window | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | seqno | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | ackno | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | payload (variable) ... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ hcs is a CRC-16-CCITT-FALSE checksum over the PCI (and the stream extension when present), verified before any flag-driven dispatch. A single packet can simultaneously carry DATA + ACK + FC + RXM by OR-ing flag bits. An optional CRC trailer covers the body on DATA when qs.ber == 0, and on every SACK packet; an optional AEAD wrap (per-flow keys) sits outermost. Flag bits (MSB-first; bits 13..15 reserved, MUST be zero): +------+--------+--------+----------------------------------------+ | Bit | Mask | Name | Meaning | +------+--------+--------+----------------------------------------+ | 0 | 0x8000 | DATA | Carries caller payload | | 1 | 0x4000 | DRF | Start of a fresh data run | | 2 | 0x2000 | ACK | ackno field valid | | 3 | 0x1000 | NACK | Pre-DRF nudge (seqno informational) | | 4 | 0x0800 | FC | window field valid (rwe advertisement) | | 5 | 0x0400 | RDVS | Rendezvous probe (window-closed) | | 6 | 0x0200 | FFGM | First Fragment of a multi-fragment SDU | | 7 | 0x0100 | LFGM | Last Fragment of a multi-fragment SDU | | 8 | 0x0080 | RXM | Retransmission | | 9 | 0x0040 | SACK | Block list follows in payload | | 10 | 0x0020 | RTTP | RTT probe / echo (payload follows) | | 11 | 0x0010 | KA | Keepalive | | 12 | 0x0008 | FIN | End of stream marker | | 13-15| -- | -- | Reserved (MUST be zero) | +------+--------+--------+----------------------------------------+ (FFGM, LFGM) encodes the fragment role of a DATA packet (SCTP-style B/E): 11=SOLE, 10=FIRST, 00=MID, 01=LAST. Each fragment carries its own seqno; Retransmission recovers fragments individually, reassembly runs at consume time. In stream mode FFGM/LFGM are unused; per-byte position is carried by the stream extension below and end-of-stream is signalled by FIN on a 0-byte DATA packet. SACK payload (FRCT_ACK | FRCT_FC | FRCT_SACK): 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | n_blocks | padding (2 octets) | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | start[0] | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | end[0] | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ ... n_blocks pairs total ... Each block describes a *present* (received) range strictly above the cumulative ACK in the PCI ackno. D-SACK (RFC 2883) is signalled in-band as block[0] - no flag bit, no extra framing - and consumed by the RACK reo_wnd_mult scaler (RFC 8985 sec. 7.2). RTTP payload (FRCT_RTTP only; 24 octets): 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | probe_id | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | echo_id | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | + nonce (16 octets, echoed verbatim) + | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Stream PCI extension (in_order == STREAM only; 8 octets after the base PCI on every DATA packet): 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | start | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | end | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ start, end are monotonic 32-bit byte offsets; end - start equals the on-wire payload length. Stream mode is negotiated at flow allocation; the extension is present iff stream mode is in use, never on a per-packet basis. Service modes are an orthogonal (in_order, loss, ber) vector selected at flow_alloc; the cubes above map to the axes: +----------------+---------+------+-----+-----------------------+ | Cube | in_order| loss | ber | Engaged | +----------------+---------+------+-----+-----------------------+ | qos_raw | 0 | 1 | 1 | Raw passthrough | | qos_raw_safe | 0 | 1 | 0 | Raw + CRC trailer | | qos_rt | 1 | 1 | 1 | FRCP, no FRTX, no CRC | | qos_rt_safe | 1 | 1 | 0 | FRCP, no FRTX, CRC | | qos_msg | 1 | 0 | 0 | FRCP + FRTX | | qos_stream | 2 | 0 | 0 | FRCP + FRTX, stream | +----------------+---------+------+-----+-----------------------+ in_order=0 sends raw datagrams with no PCI (UDP-equivalent); in_order=1 engages FRCP with SDU framing; in_order=2 (stream) requires loss=0 and is rejected otherwise. loss=0 engages the FRTX retransmit machinery. ber=0 appends the CRC-32 trailer; QOS_DISABLE_CRC at build time forces ber=1 for development. Encryption is a separate per-flow attribute layered as an AEAD wrap outside the FRCP packet. Heritage: delta-t (Watson 1981) supplies timer-based connection management - no SYN/FIN handshake, the DRF marker, the t_mpl / t_a / t_r timers. RINA (Day 2008) supplies the unified flow_alloc(name, qos, ...) primitive and the orthogonal QoS-cube axes. Loss detection follows TCP/QUIC practice (RFCs 2018, 2883, 6582, 6298, 8985); RTT probing is nonce-authenticated like QUIC PATH_CHALLENGE. Adds oftp, a minimal file-transfer tool over an FRCP stream flow. The client reads from stdin or --in FILE and writes through a flow_alloc(qos_stream); the server (--listen) calls flow_accept and writes to stdout or --out FILE. Both sides compute a CRC-64/NVMe over the bytes they handle and print the result. The server rejects flows whose negotiated qs.in_order != STREAM. Two FRCP knobs are exposed via env vars on either side: OFTP_FRCT_RTO_MIN fccntl FRCTSRTOMIN (ns) OFTP_FRCT_STREAM_RING_SZ fccntl FRCTSRRINGSZ (octets) The ocbr_client gains an OCBR_QOS env var to pick the cube the client uses for flow_alloc; recognised values are raw, safe, rt, rt_safe, msg, stream. Unknown values fall back to raw with a warning on stderr. Without the env set behaviour is unchanged.

* irmd: Allow direct rbuff between local processesDimitri Staessens2026-02-223-24/+181
| | | | | | | | | | | | | | | | | | | | | | 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 <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>

* lib: Add per-user packet poolsDimitri Staessens2026-02-133-38/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRMd will now check the user UID and GID for privileged access, avoiding unprivileged users being able to disrupt all IPC (e.g. by shm_open the single pool and corrupting its metadata). Non-privileged users are now limited to a PUP (per-user pool) for sending/receiving packets. It is still created by the IRMd, but owned by the user (uid) with 600 permissions. It does not add additional copies for local IPC between their own processes (i.e. over the local IPCP), but packets between processes owned by a different user or destined over the network (other IPCPs) will incur a copy when crossing the PUP / PUP or the PUP / GSPP boundary. Privileged users and users in the ouroboros group still have direct access to the GSPP (globally shared private pool) for packet transfer that will avoid additional copies when processing packets between processes owned by different users and to the network. This aligns the security model with UNIX trust domains defined by UID and GID by leveraging file permission on the pools in shared memory. ┌─────────────────────────────────────────────────────────────┐ │ Source Pool │ Dest Pool │ Operation │ Copies │ ├─────────────────────────────────────────────────────────────┤ │ GSPP │ GSPP │ Zero-copy │ 0 │ │ PUP.uid │ PUP.uid │ Zero-copy │ 0 │ │ PUP.uid1 │ PUP.uid2 │ memcpy() │ 1 │ │ PUP.uid │ GSPP │ memcpy() │ 1 │ │ GSPP │ PUP.uid │ memcpy() │ 1 │ └─────────────────────────────────────────────────────────────┘ This also renames the struct ai ("application instance") in dev.c to struct proc (process).

* lib: Move encryption control from QoS to nameDimitri Staessens2025-09-102-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the flow encryption option (cypher_s) from the qosspec. The configuration file is configured in the security options (default /etc/ouroboros/security/). For this poc, encryption can be disabled client or server side by putting an enc.cfg file. If that file is present in the client folder, the client will require encryption. If that file is present on the server side, the server will require encryption and reject non-encrypted flows. Encryption is now configured outside of any application control. Example: /etc/ouroboros/security/client/oping/enc.cfg exists: irmd(II): Encryption enabled for oping. irmd(DB): File /etc/ouroboros/security/client/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd(DB): Generated ephemeral keys for 87474. irmd/oap(PP): OAP_HDR [caf203681d997941 @ 2025-09-02 17:08:05 (UTC) ] --> irmd/oap(PP): Certificate: <none> irmd/oap(PP): Ephemeral Public Key: [91 bytes] irmd/oap(PP): Data: <none> irmd/oap(PP): Signature: <none> Example: /etc/ouroboros/security/client/oping/enc.cfg does not exist: irmd(II): Allocating flow for 87506 to oping. irmd(DB): File /etc/ouroboros/security/client/oping/enc.cfg does not exist. irmd(DB): File /etc/ouroboros/security/client/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd/oap(PP): OAP_HDR [e84bb9d7c3d9c002 @ 2025-09-02 17:08:30 (UTC) ] --> irmd/oap(PP): Certificate: <none> irmd/oap(PP): Ephemeral Public Key: <none> irmd/oap(PP): Data: <none> irmd/oap(PP): Signature: <none> Example: /etc/ouroboros/security/server/oping/enc.cfg exists: irmd(II): Flow request arrived for oping. irmd(DB): IPCP 88112 accepting flow 7 for oping. irmd(II): Encryption enabled for oping. irmd(DB): File /etc/ouroboros/security/server/oping/crt.pem does not exist. irmd(II): No security info for oping. irmd/oap(PP): OAP_HDR [3c717b3f31dff8df @ 2025-09-02 17:13:06 (UTC) ] <-- irmd/oap(PP): Certificate: <none> irmd/oap(PP): Ephemeral Public Key: <none> irmd/oap(PP): Data: <none> irmd/oap(PP): Signature: <none> irmd(WW): Encryption required but no key provided. The server side will pass the ECRYPT to the client: $ oping -l Ouroboros ping server started. Failed to accept flow: -1008 $ oping -n oping -c 1 Failed to allocate flow: -1008. Encryption on flows can now be changed at runtime without needing to touch/reconfigure/restart the process. Note: The ECRYPT result is passed on via the flow allocator responses through the IPCP (discovered/fixed some endianness issues), but the reason for rejecting the flow can be considered N+1 information...

* irmd: Initial Flow Allocation Protocol HeaderDimitri Staessens2025-07-232-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the initial version for the flow allocation protocol header between IRMd instances. This is a step towards flow authentication. The header supports secure and authenticated flow allocation, supporting certificate-based authentication and ephemeral key exchange for end-to-end encryption. id: 128-bit identifier for the entity. timestamp: 64-bit timestamp (replay protection). certificate: Certificate for authentication. public key: ECDHE public key for key exchange. data: Application data. signature: Signature for integrity/authenticity. Authentication and encryption require OpenSSL to be installed. The IRMd compares the allocation request delay with the MPL of the Layer over which the flow allocation was sent. MPL is now reported by the Layer in ms instead of seconds. Time functions revised for consistency and adds some tests. The TPM can now print thread running times in Debug builds (TPM_DEBUG_REPORT_INTERVAL) and abort processes with hung threads (TPM_DEBUG_ABORT_TIMEOUT). Long running threads waiting for input should call tpm_wait_work() to avoid trigger a process abort.

| | | | | | | | | This adds a -d, --duration option to oping. Now all durations can be specified in milliseconds (ms, default), seconds (s), minutes (m), hours (h), or days(d). Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Add out-of-order statistics to opingDimitri Staessens2018-06-052-3/+16
| | | | | | | | | This adds out-of-order statistics to the oping tool. A packet is considered out-of-order if its sequence number is lower than the highest sequence number already received.

* tools: Add timestamp option to opingSander Vrijders2018-06-012-6/+22
| | | | | | | | | This adds a timestamp option to oping, similar to the one in regular ping and rinaperf, so that we can more easily correlate time and latency. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be> Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be>

* tools: Disable partial reads in opingDimitri Staessens2018-05-072-3/+6
| | | | | | | | | The oping tool was using a 1500 byte buffer, but didn't account for partial reads when sending 1500 byte packets. This disables the partial reads. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* tools: Use non-blocking read in serversDimitri Staessens2018-03-161-1/+1
| | | | | | | | | | | The oping and ocbr servers were using non-blocking read/writes. This caused writes to fail on high-performance tests if the buffer got full, instead of waiting for a slot in the buffer. The write failure caused the server to quit. This fixes the tools by setting the I/O to blocking write and non-blocking read.

* lib: Use PTHREAD_COND_CLOCK for blocking reads0.10.6Dimitri Staessens2018-03-101-2/+5
| | | | | | | | | | | The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE clock. This causes the blocking reads not to timeout correctly. The oping was updated to detect server timeouts and finish gracefully.

* tools: Don't cancel reader thread in oping0.10.5Dimitri Staessens2018-03-051-2/+0
| | | | | | | | The reader thread was cancelled as soon as the writer was finished, which resulted in missed responses and misreported packet loss. Signed-off-by: Dimitri Staessens <dimitri.staessens@ugent.be> Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>
* build: Allow out-of-tree build of toolsDimitri Staessens2018-02-144-27/+25
| | | | | | | | | | This removes the dependencies for the tools on some ouroboros internal headers (endian.h and time_utils.h) so they can be built out-of-tree. The echo-app tool has been renamed oecho and the cbr tool has been renamed ocbr.

* build: Use GNUInstallDirs instead of hardcoded values0.9.9Sander Vrijders2018-02-061-1/+1
| | | | | | | | This changes the build to use GNUInstallDirs instead of hardcoded values. Package maintainers can then override these defaults by passing the correct value to cmake on the command line. Signed-off-by: Sander Vrijders <sander.vrijders@ugent.be>

* tools: Fix SEGV in oping clientDimitri Staessens2017-11-221-4/+8
| | | | | | | | | | | The oping client tried to cancel non-created pthreads if it was killed during flow allocation, which caused a SEGV. The threads are now stopped using a variable. Fixes bug #2.
