* [PATCH net v3 1/2] selftests: include bonding tests into the kselftest infra [not found] <cover.1660572700.git.jtoppins@redhat.com> @ 2022-08-15 15:08 ` Jonathan Toppins 2022-08-16 7:28 ` Hangbin Liu 0 siblings, 1 reply; 2+ messages in thread From: Jonathan Toppins @ 2022-08-15 15:08 UTC (permalink / raw) To: netdev; +Cc: liuhangbin, Shuah Khan, linux-kernel, linux-kselftest This creates a test collection in drivers/net/bonding for bonding specific kernel selftests. The first test is a reproducer that provisions a bond and given the specific order in how the ip-link(8) commands are issued the bond never transmits an LACPDU frame on any of its slaves. Signed-off-by: Jonathan Toppins <jtoppins@redhat.com> --- Notes: v2: * fully integrated the test into the kselftests infrastructure * moved the reproducer to under tools/testing/selftests/drivers/net/bonding * reduced the test to its minimial amount and used ip-link(8) for all bond interface configuration v3: * rebase to latest net/master * remove `#set -x` requested by Hangbin MAINTAINERS | 1 + tools/testing/selftests/Makefile | 1 + .../selftests/drivers/net/bonding/Makefile | 6 ++ .../net/bonding/bond-break-lacpdu-tx.sh | 81 +++++++++++++++++++ .../selftests/drivers/net/bonding/config | 1 + .../selftests/drivers/net/bonding/settings | 1 + 6 files changed, 91 insertions(+) create mode 100644 tools/testing/selftests/drivers/net/bonding/Makefile create mode 100755 tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh create mode 100644 tools/testing/selftests/drivers/net/bonding/config create mode 100644 tools/testing/selftests/drivers/net/bonding/settings diff --git a/MAINTAINERS b/MAINTAINERS index f2d64020399b..e5fb14dc302d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3672,6 +3672,7 @@ F: Documentation/networking/bonding.rst F: drivers/net/bonding/ F: include/net/bond* F: include/uapi/linux/if_bonding.h +F: tools/testing/selftests/net/bonding/ BOSCH SENSORTEC BMA400 ACCELEROMETER IIO DRIVER M: Dan Robertson <dan@dlrobertson.com> diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 10b34bb03bc1..c2064a35688b 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -12,6 +12,7 @@ TARGETS += cpu-hotplug TARGETS += damon TARGETS += drivers/dma-buf TARGETS += drivers/s390x/uvdevice +TARGETS += drivers/net/bonding TARGETS += efivarfs TARGETS += exec TARGETS += filesystems diff --git a/tools/testing/selftests/drivers/net/bonding/Makefile b/tools/testing/selftests/drivers/net/bonding/Makefile new file mode 100644 index 000000000000..ab6c54b12098 --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/Makefile @@ -0,0 +1,6 @@ +# SPDX-License-Identifier: GPL-2.0 +# Makefile for net selftests + +TEST_PROGS := bond-break-lacpdu-tx.sh + +include ../../../lib.mk diff --git a/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh b/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh new file mode 100755 index 000000000000..47ab90596acb --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/bond-break-lacpdu-tx.sh @@ -0,0 +1,81 @@ +#!/bin/sh +# SPDX-License-Identifier: GPL-2.0 + +# Regression Test: +# Verify LACPDUs get transmitted after setting the MAC address of +# the bond. +# +# https://bugzilla.redhat.com/show_bug.cgi?id=2020773 +# +# +---------+ +# | fab-br0 | +# +---------+ +# | +# +---------+ +# | fbond | +# +---------+ +# | | +# +------+ +------+ +# |veth1 | |veth2 | +# +------+ +------+ +# +# We use veths instead of physical interfaces + +set -e +tmp=$(mktemp -q dump.XXXXXX) +cleanup() { + ip link del fab-br0 >/dev/null 2>&1 || : + ip link del fbond >/dev/null 2>&1 || : + ip link del veth1-bond >/dev/null 2>&1 || : + ip link del veth2-bond >/dev/null 2>&1 || : + modprobe -r bonding >/dev/null 2>&1 || : + rm -f -- ${tmp} +} + +trap cleanup 0 1 2 +cleanup +sleep 1 + +# create the bridge +ip link add fab-br0 address 52:54:00:3B:7C:A6 mtu 1500 type bridge \ + forward_delay 15 + +# create the bond +ip link add fbond type bond mode 4 miimon 200 xmit_hash_policy 1 \ + ad_actor_sys_prio 65535 lacp_rate fast + +# set bond address +ip link set fbond address 52:54:00:3B:7C:A6 +ip link set fbond up + +# set again bond sysfs parameters +ip link set fbond type bond ad_actor_sys_prio 65535 + +# create veths +ip link add name veth1-bond type veth peer name veth1-end +ip link add name veth2-bond type veth peer name veth2-end + +# add ports +ip link set fbond master fab-br0 +ip link set veth1-bond down master fbond +ip link set veth2-bond down master fbond + +# bring up +ip link set veth1-end up +ip link set veth2-end up +ip link set fab-br0 up +ip link set fbond up +ip addr add dev fab-br0 10.0.0.3 + +tcpdump -n -i veth1-end -e ether proto 0x8809 >${tmp} 2>&1 & +sleep 15 +pkill tcpdump >/dev/null 2>&1 +rc=0 +num=$(grep "packets captured" ${tmp} | awk '{print $1}') +if test "$num" -gt 0; then + echo "PASS, captured ${num}" +else + echo "FAIL" + rc=1 +fi +exit $rc diff --git a/tools/testing/selftests/drivers/net/bonding/config b/tools/testing/selftests/drivers/net/bonding/config new file mode 100644 index 000000000000..dc1c22de3c92 --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/config @@ -0,0 +1 @@ +CONFIG_BONDING=y diff --git a/tools/testing/selftests/drivers/net/bonding/settings b/tools/testing/selftests/drivers/net/bonding/settings new file mode 100644 index 000000000000..867e118223cd --- /dev/null +++ b/tools/testing/selftests/drivers/net/bonding/settings @@ -0,0 +1 @@ +timeout=60 -- 2.31.1 ^ permalink raw reply related [flat|nested] 2+ messages in thread
