2024-09-11selftests: mptcp: include net_helper.sh fileMatthieu Baerts (NGI0)1-1/+1
Similar to the previous commit, the net_helper.sh file from the parent directory is used by the MPTCP selftests and it needs to be present when running the tests. This file then needs to be listed in the Makefile to be included when exporting or installing the tests, e.g. with: make -C tools/testing/selftests \ TARGETS=net/mptcp \ install INSTALL_PATH=$KSFT_INSTALL_PATH cd $KSFT_INSTALL_PATH ./run_kselftest.sh -c net/mptcp Fixes: 1af3bc912eac ("selftests: mptcp: lib: use wait_local_port_listen helper") Signed-off-by: Matthieu Baerts (NGI0) <[email protected]> Link: https://patch.msgid.link/20240910-net-selftests-mptcp-fix-install-v1-3-8f124aa9156d@kernel.org Signed-off-by: Jakub Kicinski <[email protected]>

2023-05-30selftests: mptcp: connect: skip if MPTCP is not supportedMatthieu Baerts1-1/+1
Selftests are supposed to run on any kernels, including the old ones not supporting MPTCP. A new check is then added to make sure MPTCP is supported. If not, the test stops and is marked as "skipped". Note that this check can also mark the test as failed if 'SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES' env var is set to 1: by doing that, we can make sure a test is not being skipped by mistake. A new shared file is added here to be able to re-used the same check in the different selftests we have.

2022-07-11selftests: stop using KSFT_KHDR_INSTALLGuillaume Tucker1-1/+0
Stop using the KSFT_KHDR_INSTALL flag as installing the kernel headers from the kselftest Makefile is causing some issues. Instead, rely on the headers to be installed directly by the top-level Makefile "headers_install" make target prior to building kselftest.

2022-07-11selftests: mptcp: validate userspace PM tests by defaultMatthieu Baerts1-1/+1
The new script was not listed in the programs to test. By consequence, some CIs running MPTCP selftests were not validating these new tests. Note that MPTCP CI was validating it as it executes all .sh scripts from 'tools/testing/selftests/net/mptcp' directory.

2021-12-07selftests: mptcp: add inq test caseFlorian Westphal1-1/+1
client & server use a unix socket connection to communicate outside of the mptcp connection. This allows the consumer to know in advance how many bytes have been (or will be) sent by the peer. This allows stricter checks on the bytecounts reported by TCP_INQ cmsg.

2021-09-18selftests: mptcp: add mptcp getsockopt test casesFlorian Westphal1-1/+1
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.

Extend mptcp_connect tool with SO_MARK support (-M <value>) and add a test case that checks that the packet mark gets copied to all subflows. This is done by only allowing packets with either skb->mark 1 or 2 via iptables. DROP rule packet counter is checked; if its not zero, print an error message and fail the test case.

2020-02-20selftests: Install settings files to fix TIMEOUT failuresMichael Ellerman1-0/+2
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") added a 45 second timeout for tests, and also added a way for tests to customise the timeout via a settings file. For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.

2020-01-24mptcp: add basic kselftest for mptcpFlorian Westphal1-0/+13
Add mptcp_connect tool: xmit two files back and forth between two processes, several net namespaces including some adding delays, losses and reordering. Wrapper script tests that data was transmitted without corruption. The "-c" command line option for mptcp_connect.sh is there for debugging: The script will use tcpdump to create one .pcap file per test case, named according to the namespaces, protocols, and connect address in use. For example, the first test case writes the capture to ns1-ns1-MPTCP-MPTCP-10.0.1.1.pcap. The stderr output from tcpdump is printed after the test completes to show tcpdump's "packets dropped by kernel" information. Also check that userspace can't create MPTCP sockets when mptcp.enabled sysctl is off. The "-b" option allows to tune/lower send buffer size. "-m mmap" can be used to test blocking io. Default is non-blocking io using read/write/poll. Will run automatically on "make kselftest". Note that the default timeout of 45 seconds is used even if there is a "settings" changing it to 450. 45 seconds should be enough in most cases but this depends on the machine running the tests. A fix to correctly read the "settings" file has been proposed upstream but not applied yet. It is not blocking the execution of these new tests but it would be nice to have it: https://patchwork.kernel.org/patch/11204935/ Co-developed-by: Paolo Abeni <[email protected]> Signed-off-by: Paolo Abeni <[email protected]> Co-developed-by: Mat Martineau <[email protected]> Signed-off-by: Mat Martineau <[email protected]> Co-developed-by: Matthieu Baerts <[email protected]> Signed-off-by: Matthieu Baerts <[email protected]> Co-developed-by: Davide Caratti <[email protected]> Signed-off-by: Davide Caratti <[email protected]> Signed-off-by: Florian Westphal <[email protected]> Signed-off-by: Christoph Paasch <[email protected]> Signed-off-by: David S.
