[PATCH v3 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. - Changelog - v2 -> v3: - Keep alphabetical order of .gitignore and Makefile [drjones] - Use memory region flags equals to zero [drjones] - Changed mmap() assert from 'mem != NULL' to 'mem != MAP_FAILED' [drjones] - kvm_region is declared along side other variables and malloc()'ed later [drjones] - Combined two asserts into a single 'ret == -1 && errno == EINVAL' [drjones] v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite". v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Wainer dos Santos Moschetta (2): selftests: kvm: Add vm_get_fd() in kvm_util selftests: kvm: Add mem_slot_test test tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 3 + .../testing/selftests/kvm/include/kvm_util.h | 1 + tools/testing/selftests/kvm/lib/kvm_util.c | 5 ++ tools/testing/selftests/kvm/mem_slot_test.c | 85 +++++++++++++++++++ 5 files changed, 95 insertions(+) create mode 100644 tools/testing/selftests/kvm/mem_slot_test.c -- 2.17.2

[PATCH] selftests: Fix memfd test run-time regression

by Shuah Khan

Commit d3fd949abd3e ("selftests: Fix memfd to support relocatable build (O=objdir)") introduced regression run-time regression with a change to include programs that should be run from shell scripts to list of programs that run as independent tests.

[PATCH v3, RESEND] kunit: Fix kunit.py run --build_dir='<foo>' fails on "unclean" trees

by Vitor Massaru Iha

Fix this bug: https://bugzilla.kernel.org/show_bug.cgi?id=205219 For some reason, the environment variable ARCH is used instead of ARCH passed as an argument, this patch uses a copy of the env, but using ARCH=um and CROSS_COMPILER='' to avoid this problem. This patch doesn't change the user's environment variables, avoiding side effects.

[PATCH v2 0/2] selftests: kvm: Introduce the mem_slot_test test

by Wainer dos Santos Moschetta

This series introduces a new KVM selftest (mem_slot_test) that goal is to verify memory slots can be added up to the maximum allowed. An extra slot is attempted which should occur on error. The patch 01 is needed so that the VM fd can be accessed from the test code (for the ioctl call attempting to add an extra slot). I ran the test successfully on x86_64, aarch64, and s390x. This is why it is enabled to build on those arches. v1: https://lore.kernel.org/kvm/20200330204310.21736-1-wainersm@redhat.com Changes v1 -> v2: - Rebased to queue - vm_get_fd() returns int instead of unsigned int (patch 01) [drjones] - Removed MEM_REG_FLAGS and GUEST_VM_MODE defines [drjones] - Replaced DEBUG() with pr_info() [drjones] - Calculate number of guest pages with vm_calc_num_guest_pages() [drjones] - Using memory region of 1 MB sized (matches mininum needed for s390x) - Removed the increment of guest_addr after the loop [drjones] - Added assert for the errno when adding a slot beyond-the-limit [drjones] - Prefer KVM_MEM_READONLY flag but on s390x it switch to KVM_MEM_LOG_DIRTY_PAGES, so ensure the coverage of both flags. Also somewhat tests the KVM_CAP_READONLY_MEM capability check [drjones] - Moved the test logic to test_add_max_slots(), this allows to more easily add new cases in the "suite".

[PATCH AUTOSEL 5.4 22/32] selftests/net: add definition for SOL_DCCP to fix compilation errors for old libc

by Sasha Levin

From: Alan Maguire <alan.maguire(a)oracle.com> [ Upstream commit 83a9b6f639e9f6b632337f9776de17d51d969c77 ] Many systems build/test up-to-date kernels with older libcs, and an older glibc (2.17) lacks the definition of SOL_DCCP in /usr/include/bits/socket.h (it was added in the 4.6 timeframe). Adding the definition to the test program avoids a compilation failure that gets in the way of building tools/testing/selftests/net. The test itself will work once the definition is added; either skipping due to DCCP not being configured in the kernel under test or passing, so there are no other more up-to-date glibc dependencies here it seems beyond that missing definition.
