[PATCH] selftests: net: properly support IPv6 in GSO GRE test

by Andrea Righi

Explicitly pass -6 to netcat when the test is using IPv6 to prevent failures. Also make sure to pass "-N" to netcat to close the socket after EOF on the client side, otherwise we would always hit the timeout and the test would fail. Without this fix applied: TEST: GREv6/v4 - copy file w/ TSO [FAIL] TEST: GREv6/v4 - copy file w/ GSO [FAIL] TEST: GREv6/v6 - copy file w/ TSO [FAIL] TEST: GREv6/v6 - copy file w/ GSO [FAIL] With this fix applied: TEST: GREv6/v4 - copy file w/ TSO [ OK ] TEST: GREv6/v4 - copy file w/ GSO [ OK ] TEST: GREv6/v6 - copy file w/ TSO [ OK ] TEST: GREv6/v6 - copy file w/ GSO [ OK ] Fixes: 025efa0a82df ("selftests: add simple GSO GRE test") Signed-off-by: Andrea Righi <andrea.righi(a)canonical.com> --- tools/testing/selftests/net/gre_gso.sh | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/gre_gso.sh b/tools/testing/selftests/net/gre_gso.sh index facbb0c80443..fdeb44d621eb 100755 --- a/tools/testing/selftests/net/gre_gso.sh +++ b/tools/testing/selftests/net/gre_gso.sh @@ -116,17 +116,18 @@ gre_gst_test_checks() { local name=$1 local addr=$2 + local proto=$3 - $NS_EXEC nc -kl $port >/dev/null & + $NS_EXEC nc $proto -kl $port >/dev/null & PID=$! while ! $NS_EXEC ss -ltn | grep -q $port; do ((i++)); sleep 0.01; done - cat $TMPFILE | timeout 1 nc $addr $port + cat $TMPFILE | timeout 1 nc $proto -N $addr $port log_test $? 0 "$name - copy file w/ TSO" ethtool -K veth0 tso off - cat $TMPFILE | timeout 1 nc $addr $port + cat $TMPFILE | timeout 1 nc $proto -N $addr $port log_test $? 0 "$name - copy file w/ GSO" ethtool -K veth0 tso on @@ -155,7 +156,7 @@ gre6_gso_test() sleep 2 gre_gst_test_checks GREv6/v4 172.16.2.2 - gre_gst_test_checks GREv6/v6 2001:db8:1::2 + gre_gst_test_checks GREv6/v6 2001:db8:1::2 -6 cleanup } -- 2.32.0

[RFC PATCH 0/1] drm: selftest: Convert to KUnit

by André Almeida

Hi, This RFC is a preview of the progress we made in the KUnit hackathon[0]. This patch, made by Maíra and Arthur, converts the damage helper test from the original DRM selftest framework to use the KUnit framework. [0] https://groups.google.com/g/kunit-dev/c/YqFR1q2uZvk/m/IbvItSfHBAAJ The IGT part of this work can be found here: https://gitlab.freedesktop.org/isinyaaa/igt-gpu-tools/-/tree/introduce-kunit We also have patches in progress converting the following tests: framebuffer, cmdline_parser, dp_mst_helper, rect and dma-buf. As soon as we sort out if this is the right way to proceed in both kernel and IGT side, the hackathon participants will submit them. Below, a dmesg output followed by the IGT output of the damage helper test. Thanks!

[PATCH] selftests: net: test_vxlan_under_vrf: fix HV connectivity test

by Andrea 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).

[PATCH 00/11] selftests: Improve nettest and net/fcnal-test.sh

by Leonard Crestez

This is a series of improvements to nettest and fcnal-test.sh from tools/testing/selftests/net which make tests run faster. For me this reduces the runtime from ~40minutes to ~5minutes and makes the tcp tests very fast. Some of the early commits are outright bugfixes. The tests DO NOT pass perfectly for me on latest net-next/master but I verified that the failures also happen without my changes. Here is the list of failures: TEST: ping local, VRF bind - VRF IP [FAIL] TEST: Raw socket bind to local address - VRF IP [FAIL] TEST: ping out, VRF bind - ns-B IPv6 LLA [FAIL] TEST: ping out, VRF bind - multicast IP [FAIL] TEST: TCP socket bind to out of scope local address - ns-A loopback IPv6 [FAIL] TEST: TCP socket bind to VRF address with device bind - VRF IPv6 [FAIL] Three of those were not tested by default before my changes, only with explicit -t 'bind bind6' This is related to my work on TCP-AO but there are no patch dependencies Link: https://lore.kernel.org/netdev/cover.1632240523.git.cdleonard@gmail.com/ Leonard Crestez (11): selftests: net/fcnal: Fix {ipv4,ipv6}_bind not run by default selftests: net/fcnal: Mark unknown -t or TESTS value as error selftests: net/fcnal: Non-zero exit on failures selftests: net/fcnal: Use accept_dad=0 to avoid setup sleep selftests: net/fcnal: kill_procs via spin instead of sleep selftests: net/fcnal: Do not capture do_run_cmd in verbose mode selftests: nettest: Implement -k to fork after bind or listen selftests: net/fcnal: Replace sleep after server start with -k selftests: nettest: Convert timeout to miliseconds selftests: nettest: Add NETTEST_CLIENT,SERVER}_TIMEOUT envvars selftests: net/fcnal: Reduce client timeout tools/testing/selftests/net/fcnal-test.sh | 710 ++++++++-------------- tools/testing/selftests/net/nettest.c | 134 +++- 2 files changed, 378 insertions(+), 466 deletions(-) base-commit: 0693b27644f04852e46f7f034e3143992b658869 -- 2.25.1

[PATCH v2 2/2] selftests/x86/amx: Update the ARCH_REQ_XCOMP_PERM test

by Chang S. Bae

Update the arch_prctl test to check the permission bitmap whether the requested feature is added as expected or not. Every non-dynamic feature that is enabled is permitted already for use. TILECFG is not dynamic feature. Ensure the bit is always on from ARCH_GET_XCOMP_PERM. Signed-off-by: Chang S.
