In `@src/plugins/gpunetio/gpunetio_backend.cpp`:
- Around line 21-63: Configure SO_RCVTIMEO and SO_SNDTIMEO on both accepted OOB
sockets in threadProgressFunc and client sockets created for connection setup,
using the existing socket setup paths. Ensure sendAll and recvAll return failure
when the timeout produces EAGAIN or EWOULDBLOCK, allowing setup and
progressThreadStop to continue instead of blocking indefinitely.
- Around line 488-496: Fix the early-return cleanup in
src/plugins/gpunetio/gpunetio_backend.cpp:488-496, 1248-1254, and 1308-1314. In
the function allocating notif near line 449, use RAII with
std::unique_ptr<nixlDocaNotif> and release it only after successful insertion
into notifMap, or delete it before the invalid-parameter return; delete the treq
allocated near line 1232 before both missing-map and missing-notification
returns. Preserve ownership transfer on successful paths.
- Line 734: Initialize the gpunetio backend’s lid member to a defined value for
every link layer, including the RoCE/Ethernet path, before it is sent by the
client and server sendAll calls. Update the constructor or member initialization
near the lid declaration, preserving the existing InfiniBand assignment and
ensuring both paths transmit an initialized value.
- Around line 837-847: Validate msg_size in recvRemoteAgentName against a fixed
maximum before calling remote_agent.resize, rejecting values above the
configured agent-name limit with NIXL_ERR_BACKEND. Define and reuse
DOCA_MAX_AGENT_NAME_SIZE from gpunetio_backend_aux.h, while preserving the
existing zero-size rejection.
- Around line 701-711: The QP metadata exchange and connection are not
serialized per nixlDocaRdmaQp, allowing connectClientRdmaQp and
connectServerRdmaQp to overwrite shared fields before connection. Acquire
connectLock or a per-QP mutex before updating rqpn_data, rqpn_notif, remote_gid,
and remote_lid, and hold it through connect_verbs_qp; alternatively skip the
exchange and connection when connMap already contains the peer.
In `@src/plugins/gpunetio/gpunetio_oob_endpoint.h`:
- Around line 17-19: Rename the constant GPUNETIO_DEFAULT_OOB_PORT to the
required snake_case identifier and rename the type GpunetioOobEndpoint to lower
camel case, then update every consumer and reference consistently.
- Line 19: Add Doxygen comments for the public struct GpunetioOobEndpoint and
the functions parseGpunetioOobPort, parseGpunetioOobEndpoint, and
formatGpunetioOobEndpoint. Document accepted inputs, default-port behavior,
return values, and exceptions thrown, using the APIs’ existing behavior and
types.
- Around line 6-7: Update the header guard in gpunetio_oob_endpoint.h by
replacing GPUNETIO_OOB_ENDPOINT_H with the repository-relative uppercase guard
NIXL_SRC_PLUGINS_GPUNETIO_GPUNETIO_OOB_ENDPOINT_H, including both the `#ifndef`
and `#define` directives.
In `@src/plugins/gpunetio/README.md`:
- Line 40: Update the oob_port configuration description in the README to state
that it must be an integer in the inclusive range [1, 65535], while retaining
the existing default and distinct-port guidance.
In `@test/unit/plugins/gpunetio/meson.build`:
- Line 22: Update the gpunetio_oob_endpoint_test Meson executable target to use
install: true instead of install: false, while leaving the mt_test exception
unchanged.

What?
Make GPUNETIO connection setup unambiguous when several peers or backend instances initialize concurrently.
This change:
oob_portbackend parameter;IPv4:port;SO_REUSEPORT, so two backends accidentally using the same address and port fail during setup instead of sharing a listener;SOMAXCONN;Why?
The GPUNETIO engine previously reused one remote GID/LID pair while multiple peer connections populated and transitioned different QPs. A connection could therefore consume route state written by another connection. On a shared host network namespace,
SO_REUSEPORTalso allowed multiple backend listeners on the default port, making the receiving rank ambiguous.The result can be a QP connected to the wrong peer and later CQ failures. Connection identity and route state must be fixed before data transfer begins.
How?
Connection metadata remains backward compatible:
Each backend binds one explicit endpoint. Each
nixlDocaRdmaQpowns its received remote GID and LID, andconnect_verbs_qp()consumes those values directly.Scope
This PR does not change peer-memory registration, WRITE coalescing, notification polling, request-ring sizing/publication, or NIXLBench CLI wiring. NIXLBench forwarding is proposed separately in #2173.
The H20 DOCA 3.1 environment also requires the compatibility and bonded-RoCE work in #2052; that is an environment dependency for the live validation, not a source dependency of the endpoint/route-state design.
Validation
-Wall -Wextra -Werror: PASS.git diff --check: PASS.werror=trueon H20/DOCA 3.1 plus the GPUNetIO: support bonded RoCE interfaces and on DOCA 3.1 #2052 compatibility patch: PASS.Integration evidence with #2052 and the later GPUNETIO data-path stack:
That H20 row validates the combined stack. It is not presented as an isolated performance result for this correctness-only diff.
