mptcp: add basic kselftest for mptcp 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 <pabeni@redhat.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com> Co-developed-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Co-developed-by: Matthieu Baerts <matthieu.baerts@tessares.net> Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> Co-developed-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: Davide Caratti <dcaratti@redhat.com> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Christoph Paasch <cpaasch@apple.com> Signed-off-by: David S.

CONFIG_MPTCP=y
selftests: mptcp: depends on built-in IPv6 Recently, CONFIG_MPTCP_IPV6 no longer selects CONFIG_IPV6. As a consequence, if CONFIG_MPTCP_IPV6=y is added to the kconfig, it will no longer ensure CONFIG_IPV6=y. If it is not enabled, CONFIG_MPTCP_IPV6 will stay disabled and selftests will fail. We also need CONFIG_IPV6 to be built-in. For more details, please see commit 0ed37ac586c0 ("mptcp: depends on IPV6 but not as a module"). Note that 'make kselftest-merge' will take all 'config' files found in 'tools/testsing/selftests'. Because some of them already set CONFIG_IPV6=y, MPTCP selftests were still passing. But they will fail if MPTCP selftests are launched manually after having executed this command to prepare the kernel config: ./scripts/kconfig/merge_config.sh -m .config \ ./tools/testing/selftests/net/mptcp/config Fixes: 010b430d5df5 ("mptcp: MPTCP_IPV6 should depend on IPV6 instead of selecting it") Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net> Reviewed-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Link: https://lore.kernel.org/r/20201021155549.933731-1-matthieu.baerts@tessares.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>

selftests: mptcp: add ADD_ADDR timeout test case This patch added the test case for retransmitting ADD_ADDR when timeout occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR echo packets. Here we need to slow down the transfer process of all data to let the ADD_ADDR suboptions can be retransmitted three times. So we added a new parameter "speed" for do_transfer, it can be set with fast or slow. We also added three new optional parameters for run_tests, and dropped run_remove_tests function. Since we added the netfilter rules in this test case, we need to update the "config" file.

selftests: mptcp: add infinite map testcase Add the single subflow test case for MP_FAIL, to test the infinite mapping case. Use the test_linkfail value to make 128KB test files. Add a new function reset_with_fail(), in it use 'iptables' and 'tc action pedit' rules to produce the bit flips to trigger the checksum failures. Set validate_checksum to enable checksums for the MP_FAIL tests without passing the '-C' argument. Set check_invert flag to enable the invert bytes check for the output data in check_transfer(). Instead of the file mismatch error, this test prints out the inverted bytes. Add a new function pedit_action_pkts() to get the numbers of the packets edited by the tc pedit actions. Print this numbers to the output. Also add the needed kernel configures in the selftests config file.
