[PATCH v2] selftests/net: suppress clang's "variable-sized type not at the end" warning

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns that "a variable sized type not at the end of a struct or class is a GNU extension". These cases are not easily changed, because they involve structs that are part of the API. Fortunately, however, the tests seem to be doing just fine (specifically, neither affected test runs any differently with gcc vs. clang builds, on my test system) regardless of the warning. So, all the warning is doing is preventing a clean build of selftests/net. Fix this by suppressing this particular clang warning for the selftests/net suite.

[PATCH v2] selftests/user_events: silence a clang warning: address of packed member

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftest ...clang warns about "taking address of packed member 'write_index' ". This is not particularly helpful, because the test code really wants to write to exactly this location, and if it ends up being unaligned, then the test won't work (and may segfault, depending on the CPU type). If that ever comes up, it will be obvious and can be fixed. But all it's doing now is prevent a clean clang build, so disable the warning.

[PATCH net 0/4] selftests: mptcp: mark unstable subtests as flaky

by Matthieu Baerts (NGI0)

Some subtests can be unstable, failing once every X runs. Fixing them can take time: there could be an issue in the kernel or in the subtest, and it is then important to do a proper analysis, not to hide real bugs. To avoid creating noises on the different CIs where tests are more unstable than on our side, some subtests have been marked as flaky. As a result, errors with these subtests (if any) are ignored. Note that the MPTCP CI will continue to track these flaky subtests. All these unstable subtests are also tracked by our bug tracker. These are fixes for the -net tree, because the instabilities are visible there. The first patch introducing the flake support has no 'Fixes' tags, mainly because it requires recent and important refactoring done in all MPTCP selftests. Backporting that to old versions where the flaky tests have been introduced would be too difficult, and probably not worth it. The other patches, adding MPTCP_LIB_SUBTEST_FLAKY=1, have a Fixes tag, simply to ease the backport of the future fixes removing them along with the proper fix.

[PATCH v2] selftest/timerns: fix clang build failures for abs() calls

by John Hubbard

First of all, in order to build with clang at all, one must first apply Valentin Obst's build fix for LLVM [1]. Once that is done, then when building with clang, via: make LLVM=1 -C tools/testing/selftests ...then clang warns about mismatches between the expected and required integer length being supplied to abs(3). Fix this by using the correct variant of abs(3): labs(3) or llabs(3), in these cases.
