Sat, 08 Aug 2026 18:00:44 +0200

selftests: drv-net: so_txtime: only send test traffic to sch_etfThe ETF qdiscs drops traffic without a socket or txtime. Even withparameter skip_sock_check regular traffic is affected by ETF.This test ran fine when run manually in a pure software environment.But with drv-net across two hosts tests fail as early as when callingcfg.remote.deploy due to effectively losing connectivity.Isolate the intended test traffic:- mark that with SO_MARK 100- install a regular permissive root prio qdisc for background traffic- install the ETF qdisc as leaf- install a filter that only directs SO_MARK 100 traffic to this leafTechnically other high prio traffic will map onto this leaf based onToS band mapping too. But that is immaterial in practice.Fixes: 5c6baef3885c ("selftests: drv-net: convert so_txtime to drv-net")Signed-off-by: Willem de Bruijn Link: https://patch.msgid.link/20260808160129.890119-1-willemdebruijn.kernel@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/config

Fri, 31 Jul 2026 04:15:42 +0200

selftests: drv-net: Test queue stall upon reconfigAdd a reconfig_tx_stall test that detects the possibility of a TX stallafter ring reconfiguration. The key observation is that drivers usingnetif_tx_start_all_queues() are prone to experiencing a stall whenreconfiguration completes compared to drivers usingnetif_tx_wake_all_queues(). start_all_queues only clears DRV_XOFF, whilewake_all_queues also calls __netif_schedule() to kick the qdisc. Withoutthe kick, qdisc backlog present at reconfig time can stay stuck until anew trigger is issued.The test caps the TX ring at 64 entries so it fills quickly, theninstalls FQ on a target TX queue and sends UDP packets with SO_TXTIMEscheduled in the future. With napi_defer_hard_irqs slowing completions,the small ring can fill when FQ releases the burst, leaving requeuedqdisc backlog with no FQ timer to rescue it. A subsequent ring reconfigmust wake the queues to drain the backlog. Simply starting the queues canleave it stuck.Some drivers lack backpressure on the TX path and may not be able tobuild up the qdisc backlog the test relies on. In that case report anexpected failure (xfail) instead of a hard failure.Testing on some of the existing drivers: Driver-A does not have the bug,Driver-B has the bug, Driver-C had the bug but it is fixed now.Driver-A:./drivers/net/ring_reconfig.py -t reconfig_tx_stallTAP version 131..1 Sent 1024 SO_TXTIME packets (+100ms) Backlog before reconfig: 1176378 bytesok 1 ring_reconfig.reconfig_tx_stall Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0Driver-B:TAP version 131..1 Sent 128 SO_TXTIME packets (+100ms) Sent 128 SO_TXTIME packets (+200ms) Backlog before reconfig: 148372 bytes Check| At ./drivers/net/ring_reconfig.py, line 397, in reconfig_tx_stall: Check| ksft_eq(0, backlog, Check failed 0 != 148372 qdisc backlog stuck on queue 1 after ring ....not ok 1 ring_reconfig.reconfig_tx_stall Totals: pass:0 fail:1 xfail:0 xpass:0 skip:0 error:0Driver-C:TAP version 131..1 Sent 128 SO_TXTIME packets (+100ms) Backlog before reconfig: 192278 bytesok 1 ring_reconfig.reconfig_tx_stall Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0Signed-off-by: Mohsin Bashir Link: https://patch.msgid.link/20260731021543.1058526-1-mohsin.bashr@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/config

selftests/net: psp: support PSP in NetDrvContEnv infrastructureAdd infrastructure to support PSP tests across network namespacesusing NetDrvContEnv with netkit pairs. This enables testing PSP deviceassociation, where a non-PSP-capable device (e.g. netkit) in a guestnamespace is associated with a real PSP device in the host namespace,allowing the guest to perform PSP encryption/decryption through thehost's PSP hardware.The topology is: Host NS: psp_dev_local <---> nk_host | | | | (netkit pair) | | Remote NS: psp_dev_peer Guest NS: nk_guest (responder) (PSP tests)env.py:- nk_guest_ifindex is queried after moving the device into the guest namespace, so tests can use it directly for dev-assocpsp.py:- PSP device lookup supports container environments where the PSP device is on the physical interface, not the test interface- Association helpers handle dev-assoc/dev-disassoc with defer-based cleanup to prevent state leaks on test assertion failures- main() tries NetDrvContEnv with primary_rx_redirect and falls back to NetDrvEpEnv, so existing tests continue to work without the container environmentSigned-off-by: Wei Wang Link: https://patch.msgid.link/20260608233118.2694144-8-weibunny.kernel@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/config
