[PATCH net-next 0/8] mptcp: add mixed v4/v6 support for the in-kernel PM

by Matthieu Baerts

Before these patches, the in-kernel Path-Manager would not allow, for the same MPTCP connection, having a mix of subflows in v4 and v6. MPTCP's RFC 8684 doesn't forbid that and it is even recommended to do so as the path in v4 and v6 are likely different. Some networks are also v4 or v6 only, we cannot assume they all have both v4 and v6 support. Patch 1 then removes this artificial constraint in the in-kernel PM currently enforcing there are no mixed subflows in place, either in address announcement or in subflow creation areas. Patch 2 makes sure the sk_ipv6only attribute is also propagated to subflows, just in case a new PM wouldn't respect it. Some selftests have also been added for the in-kernel PM (patch 3). Patches 4 to 8 are just some cleanups and small improvements in the printed messages in the userspace PM. It is not linked to the rest but identified when working on a related patch modifying this selftest, already in -net: commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix") --- Matthieu Baerts (6): mptcp: propagate sk_ipv6only to subflows mptcp: userspace pm: use a single point of exit selftests: mptcp: userspace: print titles selftests: mptcp: userspace: refactor asserts selftests: mptcp: userspace: print error details if any selftests: mptcp: userspace: avoid read errors Paolo Abeni (2): mptcp: let the in-kernel PM use mixed IPv4 and IPv6 addresses selftests: mptcp: add test-cases for mixed v4/v6 subflows net/mptcp/pm_netlink.c | 58 ++++---- net/mptcp/pm_userspace.c | 5 +- net/mptcp/sockopt.c | 1 + tools/testing/selftests/net/mptcp/mptcp_join.sh | 53 ++++++-- tools/testing/selftests/net/mptcp/userspace_pm.sh | 153 +++++++++++++--------- 5 files changed, 171 insertions(+), 99 deletions(-) --- base-commit: 4373a023e0388fc19e27d37f61401bce6ff4c9d7 change-id: 20230123-upstream-net-next-pm-v4-v6-b186481a4b00 Best regards, -- Matthieu Baerts <matthieu.baerts(a)tessares.net>

[PATCH 1/2] selftests: net: Fix missing nat6to4.o when running udpgro_frglist.sh

by Andrei Gherzan

From: Andrei <andrei.gherzan(a)canonical.com> The udpgro_frglist.sh uses nat6to4.o which is tested for existence in bpf/nat6to4.o (relative to the script). This is where the object is compiled. Even so, the script attempts to use it as part of tc with a different path (../bpf/nat6to4.o). As a consequence, this fails the script: Error opening object ../bpf/nat6to4.o: No such file or directory Cannot initialize ELF context! Unable to load program This change refactors these references to use a variable for consistency and also reformats two long lines.

[for-next][PATCH 02/12] tracing/selftests: Add test for event filtering on function name

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> With the new filter logic of passing in the name of a function to match an instruction pointer (or the address of the function), add a test to make sure that it is functional. This is also the first test to test plain filtering. The filtering has been tested via the trigger logic, which uses the same code, but there was nothing to test just the event filter, so this test is the first to add such a case.
