[PATCH] KVM: selftests: replace assertion with warning in access_tracking_perf_test

by Emanuele Giuseppe Esposito

Page_idle uses {ptep/pmdp}_clear_young_notify which in turn calls the mmu notifier callback ->clear_young(), which purposefully does not flush the TLB. When running the test in a nested guest, point 1. of the test doc header is violated, because KVM TLB is unbounded by size and since no flush is forced, KVM does not update the sptes accessed/idle bits resulting in guest assertion failure. More precisely, only the first ACCESS_WRITE in run_test() actually makes visible changes, because sptes are created and the accessed bit is set to 1 (or idle bit is 0). Then the first mark_memory_idle() passes since access bit is still one, and sets all pages as idle (or not accessed). When the next write is performed, the update is not flushed therefore idle is still 1 and next mark_memory_idle() fails.

[PATCH bpf-next v2] selftests/bpf: fix incorrect fcntl call (test_sockmap.c)

by Qiao Ma

In test_sockmap.c, the testcase sets socket nonblock first, and then calls select() and recvmsg() to receive data. If some error occur, nonblock setting will make recvmsg() return immediately, rather than blocking forever. However, the way to call fcntl() to set nonblock is wrong. To set socket noblock, we need to use > fcntl(fd, F_SETFL, O_NONBLOCK); rather than: > fcntl(fd, O_NONBLOCK); Signed-off-by: Qiao Ma <mqaio(a)linux.alibaba.com> --- tools/testing/selftests/bpf/test_sockmap.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/bpf/test_sockmap.c b/tools/testing/selftests/bpf/test_sockmap.c index 0fbaccdc8861..abb4102f33b0 100644 --- a/tools/testing/selftests/bpf/test_sockmap.c +++ b/tools/testing/selftests/bpf/test_sockmap.c @@ -598,7 +598,12 @@ static int msg_loop(int fd, int iov_count, int iov_length, int cnt, struct timeval timeout; fd_set w; - fcntl(fd, fd_flags); + err = fcntl(fd, F_SETFL, fd_flags); + if (err < 0) { + perror("fcntl failed"); + goto out_errno; + } + /* Account for pop bytes noting each iteration of apply will * call msg_pop_data helper so we need to account for this * by calculating the number of apply iterations.

[PATCH v1] selftests/landlock: Fix out-of-tree builds

by Mickaël Salaün

These changes simplify the Makefile and handle these 5 ways to build Landlock tests: - make -C tools/testing/selftests/landlock - make -C tools/testing/selftests TARGETS=landlock gen_tar - make TARGETS=landlock kselftest-gen_tar - make TARGETS=landlock O=build kselftest-gen_tar - make -C /tmp/linux TARGETS=landlock O=/tmp/build kselftest-gen_tar This also makes $(KHDR_INCLUDES) available to other test collections when building in their directory.
