selftests: net: rds: add getsockopt() conversion test

2026-06-11T10:19:05+00:00

Add a kselftest that exercises the RDS getsockopt() paths converted to
the getsockopt_iter() / sockopt_t callback:

- RDS_RECVERR and SO_RDS_TRANSPORT, which return their int value through
  copy_to_iter() and report the written length in opt->optlen.

- RDS_INFO_*, which obtains the userspace buffer pages with
  iov_iter_extract_pages() (including a non-zero starting page offset)
  and lets the info producers copy the snapshot in under a spinlock.

selftests: rds: report missing RDMA prereqs as XFAIL

2026-06-05T01:33:51+00:00

Make the RDMA test return XFAIL rather than skip when RXE is not
available, since the RDMA datapath is not run in netdev CI.

Change the three RDMA-prerequisite checks in check_rdma_conf() and
check_rdma_conf_enabled() to exit with KSFT_XFAIL (2) and tag their
messages [XFAIL] instead of [SKIP].

selftests: rds: support RDS built as loadable modules

2026-06-05T01:33:51+00:00

Commit 92cc6708f4a2 ("selftests: rds: config: disable modules") set
CONFIG_MODULES=n since run.sh required this kconfig. But disabling
modules also forces every =m option to =n rather than =y, which can
silently drop unrelated features.

This patch removes CONFIG_MODULES=n from the rds selftest config and
updates the check_*conf_enabled() routines to accept a config as
either built-in (=y) or modular (=m). A new probe_module() function
is added to load the backing module when a component is set to be
modular (=m).  config.sh no longer forces CONFIG_MODULES=n, so a user
who follows the SKIP message to run config.sh does not silently end
up with modules disabled again.

rds.ko itself is auto-loaded on socket creation, and rds_rdma.ko is
auto-loaded when SO_RDS_TRANSPORT is set with RDS_TRANS_IB, but the
TCP transport (rds_tcp.ko) is not auto-loaded on the bind path, so
the backing modules are loaded explicitly here.

selftests: rds: pin RDS sockets to their intended transport

2026-06-05T01:33:51+00:00

The RDS selftests create AF_RDS sockets but never selects a transport,
so the transport is chosen implicitly based on network topology when
the socket is bound.  If underlying connection establishment fails, RDS
can fall back to another transport (e.g. loopback) and the test still
passes, silently bypassing the intended datapath it is meant to
exercise.

Set SO_RDS_TRANSPORT to the proper RDS_TRANS_IB or RDS_TRANS_TCP before
they are bound, so the test fails loudly if the intended transport is
unavailable rather than passing on a different path.

selftests: rds: Rename run.sh to rds_run.sh

2026-06-05T01:33:51+00:00

This patch renames run.sh to rds_run.sh. This gives the test a
self-describing name that appears in the netdev CI dashboard.

selftests: rds: config: disable modules

2026-05-21T14:39:20+00:00

The run.sh script explicitly checks that CONFIG_MODULES is disabled.

By default, this config option is enabled. Explicitly disable it to be
able to run the RDS tests.

Note that writing '# CONFIG_(...) is not set' is usually recommended to
disable an option in the .config, but it looks like selftests usually
set 'CONFIG_(...)=n', which looks clearer.

selftests: rds: Add ROCE support to run.sh

2026-05-21T00:03:03+00:00

This patch adds support for testing rds rdma over ROCE.  A new
-r flag is added to config.sh which enables the required kernel
configs for rdma.  We also add a -T flag to run.sh, which takes
a transport option, tcp or rdma.  The rdma option will check to
ensure the proper configs have been enabled. The flag is then
passed to test.py, which will run the test over the specified
transport(s)

selftests: rds: Register network teardown via atexit

2026-05-21T00:03:03+00:00

This patch adds a teardown_tcp() helper that removes net0/net1.
The cmd calls here use fail=False so they can be called from
completed or partially-setup states on error. Also call
teardown_tcp() at the top of setup_tcp() so a previous
interrupted run does not leave net0/net1 lingering and break a
subsequent ip netns add.  Register teardown_tcp() with atexit
before setup_tcp() is invoked.

Likewise, we can simpliy stop_pcaps() handling by registering it
with atexit instead of calling it from the signal handler.

atexit handlers run on any exit path - normal completion, raised
exception, and sys.exit() from the timeout signal handler.  This
guarantees cleanup are called without further wrapping the test
body in a try/finally blocks.

atexit LIFO ordering keeps stop_pcaps before teardown_tcp so
tcpdumps are killed cleanly before their namespaces go away.

This is a preparatory cleanup for the upcoming ROCE patch which
will also register a teardown_rdma() alongside teardown_tcp()
