[PATCH] selftest: add a script to perform selftest compile tests

by Tim Bird

From: Tim Bird <tim.bird(a)sony.com> Add ksft-compile-test.sh. This is a program used to test cross-compilation and installation of selftest tests. See the test usage for help This program currently tests 3 scenarios out of a larger matrix of possibly interesting scenarios. For each scenario, it conducts multiple tests for correctness. This version tests: 1) does the test compile 2) is the kernel source directory clean after the compile 3) does the test install operation succeed 4) does the test run script reference the test Signed-off-by: Tim Bird <tim.bird(a)sony.com> --- MAINTAINERS | 6 + tools/testing/selftests/ksft-compile-test.sh | 567 +++++++++++++++++++++++++++ 2 files changed, 573 insertions(+) create mode 100755 tools/testing/selftests/ksft-compile-test.sh diff --git a/MAINTAINERS b/MAINTAINERS index cc1d18c..a6289c7 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -9127,6 +9127,12 @@ S: Maintained F: tools/testing/selftests/ F: Documentation/dev-tools/kselftest* +KERNEL SELFTEST SELFTEST +M: Tim Bird <tim.bird(a)sony.com> +L: linux-kselftest(a)vger.kernel.org +S: Maintained +F: tools/testing/selftests/ksft-compile-test.sh + KERNEL UNIT TESTING FRAMEWORK (KUnit) M: Brendan Higgins <brendanhiggins(a)google.com> L: linux-kselftest(a)vger.kernel.org diff --git a/tools/testing/selftests/ksft-compile-test.sh b/tools/testing/selftests/ksft-compile-test.sh new file mode 100755 index 0000000..e36e858 --- /dev/null +++ b/tools/testing/selftests/ksft-compile-test.sh @@ -0,0 +1,567 @@ +#!/bin/bash +# SPDX-License-Identifier: GPL-2.0-only OR MIT +# +# ksft-compile-test.sh - test compiling Linux kernel selftests under lots of +# different configurations.

[PATCH] selftests/tpm2: Change exception handling to be Python 3 compatible

by Jarkko Sakkinen

I need more time to fix all the byte array / string related stuff but it makes sense to fix the exceptions as it is fairly mechanical procedure: 1,$s/except $.*$, $.*$:/except \1(\2):/g I.e. fix the low hanging fruit first and the rest later.

[PATCH v5 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 - v4 -> v5: - Initialize the guest_addr and mem_reg_size variables on definition [krish.sadhukhan] v3 -> v4: - Discarded mem_reg_flags variable. Simply using 0 instead [drjones] - Discarded kvm_region pointer. Instead passing a compound literal in the ioctl [drjones] - All variables are declared on the declaration block [drjones] 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 | 69 +++++++++++++++++++ 5 files changed, 79 insertions(+) create mode 100644 tools/testing/selftests/kvm/mem_slot_test.c -- 2.17.2

[PATCH] tracing: Fix the race between registering 'snapshot' event trigger and triggering 'snapshot' operation

by Xiao Yang

Traced event can trigger 'snapshot' operation(i.e. calls snapshot_trigger() or snapshot_count_trigger()) when register_snapshot_trigger() has completed registration but doesn't allocate spare buffer for 'snapshot' event trigger.

[PATCH] selftests/ipc: Fix test failure seen after initial test run

by Tyler Hicks

After successfully running the IPC msgque test once, subsequent runs result in a test failure: $ sudo ./run_kselftest.sh TAP version 13 1..1 # selftests: ipc: msgque # Failed to get stats for IPC queue with id 0 # Failed to dump queue: -22 # Bail out! # # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 not ok 1 selftests: ipc: msgque # exit=1 The dump_queue() function loops through the possible message queue index values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id represents the index value. The first time the test is ran, the initial index value of 0 is valid and the test is able to complete. The index value of 0 is not valid in subsequent test runs and the loop attempts to try index values of 1, 2, 3, and so on until a valid index value is found that corresponds to the message queue created earlier in the test. The msgctl() syscall returns -1 and sets errno to EINVAL when invalid index values are used. The test failure is caused by incorrectly comparing errno to -EINVAL when cycling through possible index values. Fix invalid test failures on subsequent runs of the msgque test by correctly comparing errno values to a non-negated EINVAL.

[PATCH v3] Documentation: test.h - fix warnings

by Lothar Rubusch

Fix warnings at 'make htmldocs', and formatting issues in the resulting documentation. - test.h: Fix some typos in kernel-doc parameter description. - Documentation/*.rst: Fixing formatting issues, and a duplicate label issue, since using sphinx.ext.autosectionlabel in conf.py, referes to headers are generated automatically and sphinx will not complain about identical headers among documents anymore. The downside is, automatically generated header labels within one document now cannot be overwritten manually anymore. Thus duplicate headers within one document have to have different wording, i.e. this patch modifies some headers. - Documentation/api/*: Flipping over to a page "API" containing a single link to another page "API" seems like a formatting issue. The patch removes one level of indirection. v2: Several documentation fixes v3: Do not touch API documentation index Signed-off-by: Lothar Rubusch <l.rubusch(a)gmail.com> --- Documentation/dev-tools/kunit/start.rst | 13 ++++++++----- Documentation/dev-tools/kunit/usage.rst | 4 ++-- include/kunit/test.h | 7 ++++--- 3 files changed, 14 insertions(+), 10 deletions(-) diff --git a/Documentation/dev-tools/kunit/start.rst b/Documentation/dev-tools/kunit/start.rst index e1c5ce80ce12..bb112cf70624 100644 --- a/Documentation/dev-tools/kunit/start.rst +++ b/Documentation/dev-tools/kunit/start.rst @@ -32,15 +32,17 @@ test targets as well.

i386: selftests: vm: compaction_test: BUG: kernel NULL pointer dereference, address: 00000000

by Naresh Kamboju

On Linux mainline kernel 5.6.0 running kselftest vm compaction_test on i386 kernel running on x86_64 devices we have noticed this Kernel BUG followed by Kernel panic.
