selftests: drv-net: add userns devmem RX testAdd userns_devmem.py, which mirrors nk_devmem.py but places the netkitguest in a netns whose owning user_ns is non-init. ncdevmem is ran therevia nsenter so the bind-rx call is issued with creds that holdCAP_NET_ADMIN only in the child user_ns.Without the preceding GENL_UNS_ADMIN_PERM patch the test fails atbind-rx with EPERM, but with the patch the transfer completes and testspass.Signed-off-by: Bobby Eshleman Acked-by: Stanislav Fomichev Link: https://patch.msgid.link/20260602-nl-prov-v2-2-ad721142c641@meta.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/hw/config

e64e03b478e2da7093564819e903932fca2ddfa1 - tools/selftests: Add a VXLAN+IPsec traffic test

Wed, 22 Apr 2026 16:06:47 +0200

tools/selftests: Add a VXLAN+IPsec traffic testThere are VXLAN tests and IPsec tests, but there is no test thatcombines the two protocols and exercises the tunnel-over-ipsec codepaths. Fix that by adding a traffic test with VXLAN and IPsec usingcrypto offload. This is runnable on HW which supports ESP offload (so nonsim unfortunately).Traffic is done with iperf3 and the test validates that there are nopacket drops and iperf3 can get to at least 100 Mbps (a veryconservative value on today's crypto offload HW, as it can typicallyreach 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 TAP version 13 1..4 # Check| At ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py, # line 161, in test_vxlan_ipsec_crypto_offload: # Check| ksft_eq(drops_after - drops_before, 0, # Check failed 189 != 0 TX drops during VXLAN+IPsec # Check| At ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py, # line 163, in test_vxlan_ipsec_crypto_offload: # Check| ksft_ge(bw_gbps, 0.1, # Check failed 0.0015058278404812596 < 0.1 Minimum 100Mbps over # VXLAN+IPsec not ok 1 ipsec_vxlan.test_vxlan_ipsec_crypto_offload.outer_v4_inner_v4 ...Signed-off-by: Cosmin Ratiu Signed-off-by: Steffen Klassert List of files: /linux/tools/testing/selftests/drivers/net/hw/config
