2021-11-10selftests: forwarding: Fix packet matching in mirroring selftestsPetr Machata
In commit 6de6e46d27ef ("cls_flower: Fix inability to match GRE/IPIP packets"), cls_flower was fixed to match an outer packet of a tunneled packet as would be expected, rather than dissecting to the inner packet and matching on that. This fix uncovered several issues in packet matching in mirroring selftests: - in mirror_gre_bridge_1d_vlan.sh and mirror_gre_vlan_bridge_1q.sh, the vlan_ethtype match is copied around as "ip", even as some of the tests are running over ip6gretap. This is fixed by using an "ipv6" for vlan_ethtype in the ip6gretap tests. - in mirror_gre_changes.sh, a filter to count GRE packets is set up to match TTL of 50. This used to trigger in the offloaded datapath, where the envelope TTL was matched, but not in the software datapath, which considered TTL of the inner packet. Now that both match consistently, all the packets were double-counted. This is fixed by marking the filter as skip_hw, leaving only the SW datapath component active.

2021-11-10selftests: net: test_vxlan_under_vrf: fix HV connectivity testAndrea Righi
It looks like test_vxlan_under_vrf.sh is always failing to verify the connectivity test during the ping between the two simulated VMs. This is due to the fact that veth-hv in each VM should have a distinct MAC address. Fix by setting a unique MAC address on each simulated VM interface. Without this fix: $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh Checking HV connectivity [ OK ] Check VM connectivity through VXLAN (underlay in the default VRF) [FAIL] With this fix applied: $ sudo ./tools/testing/selftests/net/test_vxlan_under_vrf.sh Checking HV connectivity [ OK ] Check VM connectivity through VXLAN (underlay in the default VRF) [ OK ] Check VM connectivity through VXLAN (underlay in a VRF) [FAIL] NOTE: the connectivity test with the underlay VRF is still failing; it seems that ARP requests are blocked at the simulated hypervisor level, probably due to some missing ARP forwarding rules. This requires more investigation (in the meantime we may consider to set that test as expected failure - XFAIL). Signed-off-by: Andrea Righi <andrea.righi@canonical.com> Signed-off-by: David S.

2021-11-01selftests: mptcp: more stable simult_flows testsPaolo Abeni
Currently the simult_flows.sh self-tests are not very stable, especially when running on slow VMs. The tests measure runtime for transfers on multiple subflows and check that the time is near the theoretical maximum. The current test infra introduces a bit of jitter in test runtime, due to multiple explicit delays. Additionally the runtime is measured by the shell script wrapper. On a slow VM, the script overhead is measurable and subject to relevant jitter. One solution to make the test more stable would be adding more slack to the expected time; that could possibly hide real regressions. Instead move the measurement inside the command doing the transfer, and drop most unneeded sleeps.

2021-10-25selftests: mlxsw: Add helpers for skipping selftestsPetr Machata
A number of mlxsw-specific selftests currently detect whether they are run on a compatible machine, and bail out silently when not. These tests are however done in a somewhat impenetrable manner by directly comparing PCI IDs against a blacklist or a whitelist, and bailing out silently if the machine is not compatible. Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying the supported machines in a human-readable manner. If the current machine is incompatible, the helper emits a SKIP message and returns an error code, based on which the caller can gracefully bail out in a suitable way. This allows a more readable conditions such as: mlxsw_only_on_spectrum 2+ || return Convert all existing open-coded guards to the new helper. Also add two new guards to do_mark_test() and do_drop_test(), which are supported only on Spectrum-2+, but the corresponding check was not there.

This can be useful for adding tests to forwarding directory, and be able to verify that packets go through the hardware. When the flag is not set or set to 'skip_hw', tests can still be executed with veth pairs.

2021-09-27selftests: net: fib_nexthops: Wait before checking reported idle timePetr Machata
The purpose of this test is to verify that after a short activity passes, the reported time is reasonable: not zero (which could be reported by mistake), and not something outrageous (which would be indicative of an issue in used units). However, the idle time is reported in units of clock_t, or hundredths of second. If the initial sequence of commands is very quick, it is possible that the idle time is reported as just flat-out zero. When this test was recently enabled in our nightly regression, we started seeing spurious failures for exactly this reason. Therefore buffer the delay leading up to the test with a sleep, to make sure there is no legitimate way of reporting 0. Signed-off-by: Petr Machata <petrm@nvidia.com> Signed-off-by: David S.

2021-09-19selftests: net: af_unix: Fix makefile to use TEST_GEN_PROGSShuah Khan
Makefile uses TEST_PROGS instead of TEST_GEN_PROGS to define executables. TEST_PROGS is for shell scripts that need to be installed and run by the common lib.mk framework. The common framework doesn't touch TEST_PROGS when it does build and clean. As a result "make kselftest-clean" and "make clean" fail to remove executables. Run and install work because the common framework runs and installs TEST_PROGS. Build works because the Makefile defines "all" rule which is unnecessary if TEST_GEN_PROGS is used. Use TEST_GEN_PROGS so the common framework can handle build/run/ install/clean properly. Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-09-18selftests: mptcp: add mptcp getsockopt test casesFlorian Westphal
Add a test program that retrieves the three info types: 1. mptcp meta information 2. tcp info for subflow 3. subflow endpoint addresses For all three rudimentary checks are added. 1. Meta information checks that the logical mptcp sequence numbers advance as expected, based on the bytes read (init seq + bytes_received/sent) and the connection state (after close, we should exect 1 extra byte due to FIN). 2. TCP info checks the number of bytes sent/received vs. sums of read/write syscall return values. 3. Subflow endpoint addresses are checked vs. getsockname/getpeername result. Tests for forward compatibility (0-initialisation of output-only fields in mptcp_subflow_data structure) are added as well.

2021-08-26selftests/net: allow GRO coalesce test on vethPaolo Abeni
This change extends the existing GRO coalesce test to allow running on top of a veth pair, so that no H/W dep is required to run them. By default gro.sh will use the veth backend, and will try to use exiting H/W in loopback mode if a specific device name is provided with the '-i' command line option. No functional change is intended for the loopback-based tests, just move all the relevant initialization/cleanup code into the related script. Introduces a new initialization helper script for the veth backend, and plugs the correct helper script according to the provided command line. Additionally, enable veth-based tests by default. v1 -> v2: - drop unused code in setup_veth_ns() - Willem Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
