selftests: drv-net: enable devmem TCP in the test config

2026-08-03T20:25:13+00:00

The config fragment already sets CONFIG_UDMABUF=y, but kconfig silently
drops it. UDMABUF/NET_DEVMEM both depend on DMA_SHARED_BUFFER, which we
can't enable directly, so we need to enable a config that selects it. We
use SYNC_FILE for that purpose here.

Additionally, we flip on CONFIG_NET_DEVMEM as well.

selftests/net: Add hugepage kernel config dependency for zcrx

2026-06-16T01:58:01+00:00

test_iou_zcrx_large_buf in drivers/net/hw/nk_qlease.py runs iou-zcrx
with rx_buf_len > page size, backed by a hugepage-mapped area. Thus
add to the Kconfig.

selftests: drv-net: add userns devmem RX test

2026-06-06T01:10:31+00:00

Add userns_devmem.py, which mirrors nk_devmem.py but places the netkit
guest in a netns whose owning user_ns is non-init. ncdevmem is ran there
via nsenter so the bind-rx call is issued with creds that hold
CAP_NET_ADMIN only in the child user_ns.

Without the preceding GENL_UNS_ADMIN_PERM patch the test fails at
bind-rx with EPERM, but with the patch the transfer completes and tests
pass.

selftests: drv-net: tso: add new tests for ip6tnl, ipip, and sit tunnels

2026-06-02T19:14:14+00:00

Add new tunnel test cases for ip6tnl, ipip, and sit. ip6tnl supports
ipv[46] as inner l3 header, and the other two tunnels only support a
single inner l3 type.

tools/selftests: Add a VXLAN+IPsec traffic test

2026-04-28T04:47:19+00:00

There are VXLAN tests and IPsec tests, but there is no test that
combines the two protocols and exercises the tunnel-over-ipsec code
paths. Fix that by adding a traffic test with VXLAN and IPsec using
crypto offload. This is runnable on HW which supports ESP offload (so no
nsim unfortunately).

Traffic is done with iperf3 and the test validates that there are no
packet drops and iperf3 can get to at least 100 Mbps (a very
conservative value on today's crypto offload HW, as it can typically
reach multi-Gbps rates).

Ran right now, the test fails due to a recently exposed bug in xfrm,
which will be fixed in the next patch:
 # ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py

selftests: drv-net: add missing tc config options for netkit tests

2026-03-25T03:59:40+00:00

The NetDrvContEnv env context uses tc clsact qdiscs and BPF tc filters
for traffic redirection, but the kernel config options are missing from
the selftests config.

Without them, the tc qdisc installation trips on:

  CMD: tc qdisc add dev enp1s0 clsact
    EXIT: 2
    STDERR: Error: Specified qdisc kind is unknown.

  net.lib.py.utils.CmdExitFailure: Command failed

Add CONFIG_NET_CLS_ACT and CONFIG_NET_SCH_INGRESS to enable these tc
options.

Looks like neither IO_URING nor UDMABUF are enabled even tho

IO_URING gets enabled by default but UDMABUF is missing.
