Keeps the vendored client library in step with s3rdma 0.3.2, as #261 did for 0.3.1.

s3rdma_version() is the only runtime signal a consumer gets about the .so sitting beside it, so leaving 0.3.1 here while aistor ships 0.3.2 would have one version name two different builds.

Not a fix for this repo

The change in 0.3.2 — s3rdma#29, attributing a landing buffer to its sender at allocation, without which the proportional credit grants from 0.3.1 never ran at all — lives in libp2p_rdma, which this repo does not vendor. libs3rdma differs by its version string alone. This is a consistency refresh.

Contents

The two .so files, x86_64 and aarch64, plus a corrected s3rdma.h.

The header carries a documentation fix from s3rdma#31: it used to say a wildcard bind (0.0.0.0, ::) "means the same as empty", and the two differ exactly where that mattered. An empty ip falls through to cfg->device; a wildcard is non-empty and bypasses it, opening every ACTIVE rail. Comment text only — no declaration, struct, or layout change.

Walkthrough

Wildcard server addresses now open every device with an ACTIVE port. They no longer defer to cfg->device. A specified wildcard overrides the configured device.

Wildcard server addresses explicitly select all devices with ACTIVE ports instead of behaving like an empty address.

The wildcard documentation refers users to a nonexistent configuration option, which can lead to incorrect integration choices; the issue is localized and straightforward to correct.

Comment thread vendor/s3rdma/include/s3rdma.h Outdated
Keeps the vendored client library in step with s3rdma 0.3.2, as minio#261 did for
0.3.1. `s3rdma_version()` is the only runtime signal a consumer gets about the
`.so` beside it, so leaving 0.3.1 here while aistor ships 0.3.2 would have one
version name two different builds.

The change in 0.3.2 (s3rdma#29, attributing a landing buffer to its sender at
allocation, without which the proportional credit grants from 0.3.1 never ran
at all) lives in libp2p_rdma, which this repo does not vendor — the client
library differs only by its version string. Refreshed for consistency rather
than for a fix.
