[PATCH] selftests/seccomp: fix test failure on s390x because of positive error return Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit

by Colin King

From: Colin Ian King <colin.king(a)canonical.com> The error return being placed in regs.SYSCALL_RET is currently positive and this is causing test failures on s390x. The return value should be -EPERM rather than EPERM otherwise a failure is not detected and errno is not set accordingly on s390x.

[PATCH][V2] selftests: cpu-hotplug: fix case where CPUs offline > CPUs present

by Colin King

From: Colin Ian King <colin.king(a)canonical.com> The cpu-hotplug test assumes that we can offline the maximum CPU as described by /sys/devices/system/cpu/offline. However, in the case where the number of CPUs exceeds like kernel configuration then the offline count can be greater than the present count and we end up trying to test the offlining of a CPU that is not available to offline. Fix this by testing the maximum present CPU instead. Also, the test currently offlines the CPU and does not online it, so fix this by onlining the CPU after the test.

[PATCH v3] selftests: add binderfs selftests

by Christian Brauner

This adds the promised selftest for binderfs. It will verify the following things: - binderfs mounting works - binder device allocation works - performing a binder ioctl() request through a binderfs device works - binder device removal works - binder-control removal fails - binderfs unmounting works The tests are performed both privileged and unprivileged. The latter verifies that binderfs behaves correctly in user namespaces. Cc: Todd Kjos <tkjos(a)google.com> Signed-off-by: Christian Brauner <christian.brauner(a)ubuntu.com> --- /* Changelog */ v3: - s/printf/ksft_print_msg/g - do not report misleading errno on short write v2: - make failure to create /dev/binderfs directory fatal in all circumstances - make tests run in user namespace to test whether binderfs can be mounted in user namespaces and so that unprivileged users can run the tests - use ksft_exit_skip() v1: - check for ENODEV on mount failure to detect whether binderfs is available If it is not, skip the test and exit with success. --- tools/testing/selftests/Makefile | 1 + .../selftests/filesystems/binderfs/.gitignore | 1 + .../selftests/filesystems/binderfs/Makefile | 6 + .../filesystems/binderfs/binderfs_test.c | 275 ++++++++++++++++++ .../selftests/filesystems/binderfs/config | 3 + 5 files changed, 286 insertions(+) create mode 100644 tools/testing/selftests/filesystems/binderfs/.gitignore create mode 100644 tools/testing/selftests/filesystems/binderfs/Makefile create mode 100644 tools/testing/selftests/filesystems/binderfs/binderfs_test.c create mode 100644 tools/testing/selftests/filesystems/binderfs/config diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 1a2bd15c5b6e..400ee81a3043 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -10,6 +10,7 @@ TARGETS += drivers/dma-buf TARGETS += efivarfs TARGETS += exec TARGETS += filesystems +TARGETS += filesystems/binderfs TARGETS += firmware TARGETS += ftrace TARGETS += futex diff --git a/tools/testing/selftests/filesystems/binderfs/.gitignore b/tools/testing/selftests/filesystems/binderfs/.gitignore new file mode 100644 index 000000000000..8a5d9bf63dd4 --- /dev/null +++ b/tools/testing/selftests/filesystems/binderfs/.gitignore @@ -0,0 +1 @@ +binderfs_test diff --git a/tools/testing/selftests/filesystems/binderfs/Makefile b/tools/testing/selftests/filesystems/binderfs/Makefile new file mode 100644 index 000000000000..58cb659b56b4 --- /dev/null +++ b/tools/testing/selftests/filesystems/binderfs/Makefile @@ -0,0 +1,6 @@ +# SPDX-License-Identifier: GPL-2.0 + +CFLAGS += -I../../../../../usr/include/ +TEST_GEN_PROGS := binderfs_test + +include ../../lib.mk diff --git a/tools/testing/selftests/filesystems/binderfs/binderfs_test.c b/tools/testing/selftests/filesystems/binderfs/binderfs_test.c new file mode 100644 index 000000000000..8c2ed962e1c7 --- /dev/null +++ b/tools/testing/selftests/filesystems/binderfs/binderfs_test.c @@ -0,0 +1,275 @@ +// SPDX-License-Identifier: GPL-2.0 + +#define _GNU_SOURCE +#include <errno.h> +#include <fcntl.h> +#include <sched.h> +#include <stdbool.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <sys/ioctl.h> +#include <sys/mount.h> +#include <sys/stat.h> +#include <sys/types.h> +#include <unistd.h> +#include <linux/android/binder.h> +#include <linux/android/binderfs.h> +#include "../../kselftest.h" + +static ssize_t write_nointr(int fd, const void *buf, size_t count) +{ + ssize_t ret;

[PATCH] selftests: kmod: worked on errors which breaks the overall execution of the test script

by Jeffrin Jose T

The kmod.sh script breaks because an array is passed as input instead of a single element input.This patch takes elements one at a time and passed as input to the condition statement which in turn fixes the error.There was an issue which had the need for passing a single digit to the condition statement which is fixed using regular expression.

[PATCH backport for 4.19] selftests: Fix test errors related to lib.mk khdr target

by shuah＠kernel.org

From: Shuah Khan <shuah(a)kernel.org> Upstream commit 211929fd3f7c ("selftests: Fix test errors related to lib.mk khdr target") This backport drops change to test that isn't in 4.19 - tools/testing/selftests/tc-testing/bpf/Makefile The rest of the changes applied with minor changes to - tools/testing/selftests/gpio/Makefile - tools/testing/selftests/kvm/Makefile Commit b2d35fa5fc80 ("selftests: add headers_install to lib.mk") added khdr target to run headers_install target from the main Makefile. The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.
