4d4dfb20 - selftests: mptcp: increase timeout to 30 min

Wed, 31 Jan 2024 21:49:50 +0000

selftests: mptcp: increase timeout to 30 minOn very slow environments -- e.g. when QEmu is used without KVM --,mptcp_join.sh selftest can take a bit more than 20 minutes. Bump thedefault timeout by 50% as it seems normal to take that long on someenvironments.When a debug kernel config is used, this selftest will take even longer,but that's certainly not a common test env to consider for the timeout.The Fixes tag that has been picked here is there simply to help havingthis patch backported to older stable versions. It is difficult to pointto the exact commit that made some env reaching the timeout from time totime.Fixes: d17b968b9876 ("selftests: mptcp: increase timeout to 20 minutes")Cc: stable@vger.kernel.orgAcked-by: Paolo Abeni Signed-off-by: Matthieu Baerts (NGI0) Link: https://lore.kernel.org/r/20240131-upstream-net-20240131-mptcp-ci-issues-v1-5-4c1c11e571ff@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/mptcp/settings

d17b968b - selftests: mptcp: increase timeout to 20 minutes

Fri, 18 Feb 2022 03:03:05 +0000

selftests: mptcp: increase timeout to 20 minutesWith the increase number of tests, one CI instance, using a debug kernelconfig and not recent hardware, takes around 10 minutes to execute theslowest MPTCP test: mptcp_join.sh.Even if most CIs don't take that long to execute these tests --typically max 10 minutes to run all selftests -- it will help some ofthem if the timeout is increased.The timeout could be disabled but it is always good to have an extrasafeguard, just in case.Please note that on slow public CIs with kernel debug settings, it hasbeen observed it can easily take up to 45 minutes to execute all testsin this very slow environment with other jobs running in parallel.The slowest test, mptcp_join.sh takes ~30 minutes in this case.In such environments, the selftests timeout set in the 'settings' fileis disabled because this environment is known as being exceptionnallyslow. It has been decided not to take such exceptional environments intoaccount and set the timeout to 20min.Signed-off-by: Matthieu Baerts Signed-off-by: Mat Martineau Signed-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/mptcp/settings

selftests: increase timeout to 10 minOn slow systems with kernel debug settings, we can reach the currenttimeout when all tests are executed.Likely some tests need be improved to remove some 'sleep' and wait(less) for a specific action. This can also improve stability.Signed-off-by: Matthieu Baerts Signed-off-by: Mat Martineau Signed-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/mptcp/settings

048d19d4 - mptcp: add basic kselftest for mptcp

Wed, 22 Jan 2020 00:56:29 +0000

mptcp: add basic kselftest for mptcpAdd mptcp_connect tool:xmit two files back and forth between two processes, several netnamespaces 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, namedaccording to the namespaces, protocols, and connect address in use.For example, the first test case writes the capture tons1-ns1-MPTCP-MPTCP-10.0.1.1.pcap.The stderr output from tcpdump is printed after the test completes toshow tcpdump's "packets dropped by kernel" information.Also check that userspace can't create MPTCP sockets when mptcp.enabledsysctl is off.The "-b" option allows to tune/lower send buffer size."-m mmap" can be used to test blocking io. Default is non-blockingio 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 casesbut this depends on the machine running the tests.A fix to correctly read the "settings" file has been proposed upstreambut not applied yet. It is not blocking the execution of these new testsbut it would be nice to have it: https://patchwork.kernel.org/patch/11204935/Co-developed-by: Paolo Abeni Signed-off-by: Paolo Abeni Co-developed-by: Mat Martineau Signed-off-by: Mat Martineau Co-developed-by: Matthieu Baerts Signed-off-by: Matthieu Baerts Co-developed-by: Davide Caratti Signed-off-by: Davide Caratti Signed-off-by: Florian Westphal Signed-off-by: Christoph Paasch Signed-off-by: David S.
