[PATCH 1/2] userfaultfd: handle zeropage moves by UFFDIO_MOVE

by Suren Baghdasaryan

Current implementation of UFFDIO_MOVE fails to move zeropages and returns EBUSY when it encounters one. We can handle them by mapping a zeropage at the destination and clearing the mapping at the source. This is done both for ordinary and for huge zeropages.

[PATCHv2 net] selftests/net/lib: update busywait timeout value

by Hangbin Liu

The busywait timeout value is a millisecond, not a second. So the current setting 2 is too small. On slow/busy host (or VMs) the current timeout can expire even on "correct" execution, causing random failures. Let's copy the WAIT_TIMEOUT from forwarding/lib.sh and set BUSYWAIT_TIMEOUT here.

[PATCH net 0/3] selftests: net: a few fixes

by Paolo Abeni

This series address self-tests failures for udp gro-related tests. The first patch addresses the main problem I observe locally - the XDP program required by such tests, xdp_dummy, is currently build in the ebpf self-tests directory, not available if/when the user targets net only. Arguably is more a refactor than a fix, but still targeting net to hopefully The second patch fixes the integration of such tests with the build system. Patch 3/3 fixes sporadic failures due to races. Tested with: make -C tools/testing/selftests/ TARGETS=net install ./tools/testing/selftests/kselftest_install/run_kselftest.sh \ -t "net:udpgro_bench.sh net:udpgro.sh net:udpgro_fwd.sh \ net:udpgro_frglist.sh net:veth.sh" no failures.

[PATCH v4 0/2] kselftest/seccomp: Convert to KTAP output

by Mark Brown

Currently the seccomp benchmark selftest produces non-standard output, meaning that while it makes a number of checks of the performance it observes this has to be parsed by humans. This means that automated systems running this suite of tests are almost certainly ignoring the results which isn't ideal for spotting problems. Let's rework things so that each check that the program does is reported as a test result to the framework.

[PATCH net-next 0/6] selftests: Add TEST_INCLUDES directive and adjust tests to use it

by Benjamin Poirier

After commit 25ae948b4478 ("selftests/net: add lib.sh") but before commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"), some net selftests encountered errors when they were being exported and run. This was because the new net/lib.sh was not exported along with the tests. The errors were crudely avoided by duplicating some content between net/lib.sh and net/forwarding/lib.sh in 2114e83381d3. In order to restore the sourcing of net/lib.sh from net/forwarding/lib.sh and remove the duplicated content, this series introduces a new selftests Makefile variable to list extra files to export from other directories and makes use of it to avoid reintroducing the errors mentioned above. v1: * "selftests: Introduce Makefile variable to list shared bash scripts" Changed TEST_INCLUDES to take relative paths, like other TEST_* variables. Paths are adjusted accordingly in the subsequent patches. (Vladimir Oltean) * selftests: bonding: Change script interpreter selftests: forwarding: Remove executable bits from lib.sh Removed from this series, submitted separately. Since commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh") resolved the test errors, this version of the series is focused on removing the duplication that was added in that commit. Directly rebasing the series would reintroduce the problems that 2114e83381d3 avoided before fixing them again. In order to prevent such breakage partway through the series, patches are reordered and content changed slightly but there is no diff at the end compared with the simple rebasing approach. I have dropped most review tags on account of this reordering.
