selftests: ocelot: tc_flower_chains: reorder interfaces

2022-05-22T21:14:13Z

Use the standard interface order h1, swp1, swp2, h2 that is used by the forwarding selftest framework. The previous order was confusing even with the ASCII drawing. That isn't needed anymore. This also drops the fixed MAC addresses and uses STABLE_MAC_ADDRS, which ensures the MAC addresses are unique. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: ocelot: tc_flower_chains: use conventional interface names

2022-05-22T21:14:13Z

This is a robotic rename as follows: eth0 -> swp1 eth1 -> swp2 eth2 -> h2 eth3 -> h1 This brings the selftest more in line with the other forwarding selftests, where h1 is connected to swp1, and h2 to swp2. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: drivers/s390x: Add uvdevice tests

2022-05-20T14:38:42Z

Adds some selftests to test ioctl error paths of the uv-uapi. The Kconfig S390_UV_UAPI must be selected and the Ultravisor facility must be available. The test can be executed by non-root, however, the uvdevice special file /dev/uv must be accessible for reading and writing which may imply root privileges. ./test-uv-device TAP version 13 1..6 # Starting 6 tests from 3 test cases. # RUN uvio_fixture.att.fault_ioctl_arg ... # OK uvio_fixture.att.fault_ioctl_arg ok 1 uvio_fixture.att.fault_ioctl_arg # RUN uvio_fixture.att.fault_uvio_arg ... # OK uvio_fixture.att.fault_uvio_arg ok 2 uvio_fixture.att.fault_uvio_arg # RUN uvio_fixture.att.inval_ioctl_cb ... # OK uvio_fixture.att.inval_ioctl_cb ok 3 uvio_fixture.att.inval_ioctl_cb # RUN uvio_fixture.att.inval_ioctl_cmd ... # OK uvio_fixture.att.inval_ioctl_cmd ok 4 uvio_fixture.att.inval_ioctl_cmd # RUN attest_fixture.att_inval_request ... # OK attest_fixture.att_inval_request ok 5 attest_fixture.att_inval_request # RUN attest_fixture.att_inval_addr ... # OK attest_fixture.att_inval_addr ok 6 attest_fixture.att_inval_addr # PASSED: 6 / 6 tests passed. # Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0 Signed-off-by: Steffen Eiden Acked-by: Janosch Frank Message-Id: <20220510144724.3321985-3-seiden@linux.ibm.com> Link: https://lore.kernel.org/kvm/20220510144724.3321985-3-seiden@linux.ibm.com/ Signed-off-by: Janosch Frank

selftests: netdevsim: Increase sleep time in hw_stats_l3.sh test

2022-05-18T13:06:50Z

hw_stats_l3.sh test is failing often for l3 stats shows less than 20 packets after 2 seconds sleep. This is happening since there is a race between the 2 seconds sleep and the netdevsim actually delivering the packets. Increase the sleep time so the packets will be delivered successfully on time.

This reverts commit 5e927a9f4b9f29d78a7c7d66ea717bb5c8bbad8e, reversing changes made to cfc1d91a7d78cf9de25b043d81efcc16966d55b3. The discussion is still ongoing so let's remove the uAPI until the discussion settles.

selftests: ocelot: tc_flower_chains: specify conform-exceed action for policer

2022-05-05T02:40:19Z

As discussed here with Ido Schimmel: https://patchwork.kernel.org/project/netdevbpf/patch/20220224102908.5255-2-jianbol@nvidia.com/ the default conform-exceed action is "reclassify", for a reason we don't really understand. The point is that hardware can't offload that police action, so not specifying "conform-exceed" was always wrong, even though the command used to work in hardware (but not in software) until the kernel started adding validation for it. Fix the command used by the selftest by making the policer drop on exceed, and pass the packet to the next action (goto) on conform.
