[PATCH v4 0/4] selftests: kvm: s390: Add ucontrol memory selftests

by Christoph Schlameuss

This patch series adds a some not yet picked selftests to the kvm s390x selftest suite. The additional test cases are covering: * Assert KVM_EXIT_S390_UCONTROL exit on not mapped memory access * Assert functionality of storage keys in ucontrol VM * Assert that memory region operations are rejected for ucontrol VMs Running the test cases requires sys_admin capabilities to start the ucontrol VM. This can be achieved by running as root or with a command like: sudo setpriv --reuid nobody --inh-caps -all,+sys_admin \ --ambient-caps -all,+sys_admin --bounding-set -all,+sys_admin \ ./ucontrol_test --- The patches in this series have been part of the previous patch series. The test cases added here do depend on the fixture added in the earlier patches. From v5 PATCH 7-9 the segment and page table generation has been removed and DAT has been disabled. Since DAT is not necessary to validate the KVM code. https://lore.kernel.org/kvm/20240807154512.316936-1-schlameuss@linux.ibm.co… v4: - fix whitespaces in pointer function arguments (thanks Claudio) - fix whitespaces in comments (thanks Janosch) v3: - fix skey assertion (thanks Claudio) - introduce a wrapper around UCAS map and unmap ioctls to improve readability (Claudio) - add an displacement to accessed memory to assert translation intercepts actually point to segments to the uc_map_unmap test - add an misaligned failing mapping try to the uc_map_unmap test v2: - Reenable KSS intercept and handle it within skey test. - Modify the checked register between storing (sske) and reading (iske) it within the test program to make sure the. - Add an additional state assertion in the end of uc_skey - Fix some typos and white spaces. v1: - Remove segment and page table generation and disable DAT. This is not necessary to validate the KVM code.

[PATCH net-next v7 25/25] testing/selftest: add test tool and scripts for ovpn module

by Antonio Quartulli

The ovpn-cli tool can be compiled and used as selftest for the ovpn kernel module. It implementes the netlink API and can thus be integrated in any script for more automated testing. Along with the tool, 2 scripts are added that perform basic functionality tests by means of network namespaces. The scripts can be performed in sequence by running run.sh Cc: shuah(a)kernel.org Cc: linux-kselftest(a)vger.kernel.org Signed-off-by: Antonio Quartulli <antonio(a)openvpn.net> --- tools/testing/selftests/Makefile | 1 + tools/testing/selftests/net/ovpn/.gitignore | 2 + tools/testing/selftests/net/ovpn/Makefile | 17 + tools/testing/selftests/net/ovpn/config | 8 + .../selftests/net/ovpn/data-test-tcp.sh | 9 + tools/testing/selftests/net/ovpn/data-test.sh | 150 ++ tools/testing/selftests/net/ovpn/data64.key | 5 + .../testing/selftests/net/ovpn/float-test.sh | 115 ++ tools/testing/selftests/net/ovpn/ovpn-cli.c | 1820 +++++++++++++++++ .../testing/selftests/net/ovpn/tcp_peers.txt | 5 + .../testing/selftests/net/ovpn/udp_peers.txt | 5 + 11 files changed, 2137 insertions(+) create mode 100644 tools/testing/selftests/net/ovpn/.gitignore create mode 100644 tools/testing/selftests/net/ovpn/Makefile create mode 100644 tools/testing/selftests/net/ovpn/config create mode 100755 tools/testing/selftests/net/ovpn/data-test-tcp.sh create mode 100755 tools/testing/selftests/net/ovpn/data-test.sh create mode 100644 tools/testing/selftests/net/ovpn/data64.key create mode 100755 tools/testing/selftests/net/ovpn/float-test.sh create mode 100644 tools/testing/selftests/net/ovpn/ovpn-cli.c create mode 100644 tools/testing/selftests/net/ovpn/tcp_peers.txt create mode 100644 tools/testing/selftests/net/ovpn/udp_peers.txt diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 3b7df5477317..8330f031d167 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -67,6 +67,7 @@ TARGETS += net/hsr TARGETS += net/mptcp TARGETS += net/netfilter TARGETS += net/openvswitch +TARGETS += net/ovpn TARGETS += net/packetdrill TARGETS += net/rds TARGETS += net/tcp_ao diff --git a/tools/testing/selftests/net/ovpn/.gitignore b/tools/testing/selftests/net/ovpn/.gitignore new file mode 100644 index 000000000000..ee44c081ca7c --- /dev/null +++ b/tools/testing/selftests/net/ovpn/.gitignore @@ -0,0 +1,2 @@ +# SPDX-License-Identifier: GPL-2.0+ +ovpn-cli diff --git a/tools/testing/selftests/net/ovpn/Makefile b/tools/testing/selftests/net/ovpn/Makefile new file mode 100644 index 000000000000..171cf047497c --- /dev/null +++ b/tools/testing/selftests/net/ovpn/Makefile @@ -0,0 +1,17 @@ +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2020-2024 OpenVPN, Inc. +# +CFLAGS = -Wall -I../../../../../usr/include +CFLAGS += $(shell pkg-config --cflags libnl-3.0 libnl-genl-3.0) + +LDFLAGS = -lmbedtls -lmbedcrypto +LDFLAGS += $(shell pkg-config --libs libnl-3.0 libnl-genl-3.0) + +ovpn-cli: ovpn-cli.c + +TEST_PROGS = data-test.sh \ + data-test-tcp.sh \ + float-test.sh +TEST_GEN_FILES = ovpn-cli + +include ../../lib.mk diff --git a/tools/testing/selftests/net/ovpn/config b/tools/testing/selftests/net/ovpn/config new file mode 100644 index 000000000000..5ff47de23c12 --- /dev/null +++ b/tools/testing/selftests/net/ovpn/config @@ -0,0 +1,8 @@ +CONFIG_NET=y +CONFIG_INET=y +CONFIG_NET_UDP_TUNNEL=y +CONFIG_DST_CACHE=y +CONFIG_CRYPTO_AES=y +CONFIG_CRYPTO_GCM=y +CONFIG_CRYPTO_CHACHA20POLY1305=y +CONFIG_OVPN=y diff --git a/tools/testing/selftests/net/ovpn/data-test-tcp.sh b/tools/testing/selftests/net/ovpn/data-test-tcp.sh new file mode 100755 index 000000000000..65f05659b5fd --- /dev/null +++ b/tools/testing/selftests/net/ovpn/data-test-tcp.sh @@ -0,0 +1,9 @@ +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2024 OpenVPN, Inc. +# +# Author: Antonio Quartulli <antonio(a)openvpn.net> + +PROTO="TCP" + +source data-test.sh diff --git a/tools/testing/selftests/net/ovpn/data-test.sh b/tools/testing/selftests/net/ovpn/data-test.sh new file mode 100755 index 000000000000..8468defb1f1c --- /dev/null +++ b/tools/testing/selftests/net/ovpn/data-test.sh @@ -0,0 +1,150 @@ +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (C) 2020-2024 OpenVPN, Inc. +# +# Author: Antonio Quartulli <antonio(a)openvpn.net> + +#set -x +set -e + +UDP_PEERS_FILE=${UDP_PEERS_FILE:-udp_peers.txt} +TCP_PEERS_FILE=${TCP_PEERS_FILE:-tcp_peers.txt} +OVPN_CLI=${OVPN_CLI:-./ovpn-cli} +ALG=${ALG:-aes} +PROTO=${PROTO:-UDP} + +create_ns() { + ip netns add peer${1} +} + +setup_ns() { + MODE="P2P" + + if [ ${1} -eq 0 ];
