selftests: forwarding: Fix ping failure due to short timeout

2024-03-26T22:20:13+00:00

[ Upstream commit e4137851d4863a9bdc6aabc613bcb46c06d91e64 ] The tests send 100 pings in 0.1 second intervals and force a timeout of 11 seconds, which is borderline (especially on debug kernels), resulting in random failures in netdev CI [1]. Fix by increasing the timeout to 20 seconds. It should not prolong the test unless something is wrong, in which case the test will rightfully fail.

selftests: forwarding: Add missing multicast routing config entries

2024-03-26T22:19:28+00:00

[ Upstream commit f0ddf15f0a74c27eb4b2271a90e69948acc3fa2c ] The two tests that make use of multicast routig (router.sh and router_multicast.sh) are currently failing in the netdev CI because the kernel is missing multicast routing support. Fix by adding the required config entries.

selftests: forwarding: Add missing config entries

2024-03-26T22:19:28+00:00

[ Upstream commit 4acf4e62cd572b0c806035046b3698f5585ab821 ] The config file contains a partial kernel configuration to be used by `virtme-configkernel --custom'. The presumption is that the config file contains all Kconfig options needed by the selftests from the directory. In net/forwarding/config, many are missing, which manifests as spurious failures when running the selftests, with messages about unknown device types, qdisc kinds or classifier actions. Add the missing configurations. Tested the resulting configuration using virtme-ng as follows: # vng -b -f tools/testing/selftests/net/forwarding/config # vng --user root (within the VM:) # make -C tools/testing/selftests TARGETS=net/forwarding run_tests Signed-off-by: Petr Machata Link: https://lore.kernel.org/r/025abded7ff9cea5874a7fe35dcd3fd41bf5e6ac.1706286755.git.petrm@nvidia.com Signed-off-by: Paolo Abeni Stable-dep-of: f0ddf15f0a74 ("selftests: forwarding: Add missing multicast routing config entries") Signed-off-by: Sasha Levin

selftests: openvswitch: Add validation for the recursion test

2024-03-26T22:19:10+00:00

[ Upstream commit bd128f62c365504e1268dc09fcccdfb1f091e93a ] Add a test case into the netlink checks that will show the number of nested action recursions won't exceed 16. Going to 17 on a small clone call isn't enough to exhaust the stack on (most) systems, so it should be safe to run even on systems that don't have the fix applied.

selftests: mptcp: decrease BW in simult flows

2024-03-15T14:48:21+00:00

[ Upstream commit 5e2f3c65af47e527ccac54060cf909e3306652ff ] When running the simult_flow selftest in slow environments -- e.g. QEmu without KVM support --, the results can be unstable. This selftest checks if the aggregated bandwidth is (almost) fully used as expected. To help improving the stability while still keeping the same validation in place, the BW and the delay are reduced to lower the pressure on the CPU.

selftests: mptcp: rm subflow with v4/v4mapped addr

commit 7092dbee23282b6fcf1313fc64e2b92649ee16e8 upstream. Now both a v4 address and a v4-mapped address are supported when destroying a userspace pm subflow, this patch adds a second subflow to "userspace pm add & remove address" test, and two subflows could be removed two different ways, one with the v4mapped and one with v4.

selftests: mptcp: add mptcp_lib_is_v6

commit b850f2c7dd85ecd14a333685c4ffd23f12665e94 upstream. To avoid duplicated code in different MPTCP selftests, we can add and use helpers defined in mptcp_lib.sh. is_v6() helper is defined in mptcp_connect.sh, mptcp_join.sh and mptcp_sockopt.sh, so export it into mptcp_lib.sh and rename it as mptcp_lib_is_v6(). Use this new helper in all scripts.

commit 757c828ce94905a2975873d5e90a376c701b2b90 upstream. This patch adds a new argument namespace to userspace_pm_add_addr() and userspace_pm_add_sf() to make these two helper more versatile. Add two more versatile helpers for userspace pm remove subflow or address: userspace_pm_rm_addr() and userspace_pm_rm_sf().

commit 80775412882e273b8ef62124fae861cde8e6fb3d upstream. This patch adds a new helper chk_subflows_total(), in it use the newly added counter mptcpi_subflows_total to get the "correct" amount of subflows, including the initial one. To be compatible with old 'ss' or kernel versions not supporting this counter, get the total subflows by listing TCP connections that are MPTCP subflows: ss -ti state state established state syn-sent state syn-recv | grep -c tcp-ulp-mptcp.
