[PATCH 0/1] selftests: kvm: Overlapped memory regions test

by Wainer dos Santos Moschetta

This introduces a test case to check memory slots with overlapped regions on the guest address cannot be added. The cases checked are described in the block comment upon test_overlap_memory_regions() (see the patch 01). I didn't see the need to calcute the addresses on compile/run-time, so I just left them hard-coded (remember: aligned 1M to work on s390x). It works on x86_64, aarch64, and s390x. The patch is based on queue branch. Ah, I did some cosmetic changes on test_add_max_memory_regions() too. If it is not OK to be in a single patch...let me know.

[PATCH v16 00/10] Landlock LSM

by Mickaël Salaün

Hi, This new patch series brings some improvements while simplifying the code, fixes some bugs and adds more tests: Use a bitfield of layers to properly manage superset and subset of access rights, whatever their order in the stack of layers [1]. Allow to open pipes and similar special files through /proc/self/fd, as well as internal filesystems such as nsfs through /proc/self/ns, because disconnected path cannot be evaluated. Such special filesystems could be handled with a future evolution. For the sake of simplicity, forbid reparenting when linking or renaming to protect against possible privilege escalation. This could happen by changing the hierarchy of a file or directory in relation to an enforced access policy (from the set of layers). This will be relaxed in the future with more complex code. Rename the unlink and rmdir access rights to a more generic ones: remove_dir and remove_file. Indeed it makes sense to also use them for the action of renaming a file or a directory, which may lead to the removal of the source file or directory. Replace the link_to, rename_from and rename_to access rights with remove_file, remove_dir and make_* . Add multiple tests to check semantic, and improve test coverage for security/landlock to 94.1% of lines (best possible with deterministic user space tests). Add current limitations to documentation: file renaming and linking, OverlayFS and special filesystems (e.g. nsfs). The previously identified memory accounting limitation can already be solved with the (kernel) Memory Resource Controller from cgroup. The SLOC count is 1267 for security/landlock/ and 1643 for tools/testing/selftest/landlock/ . The compiled documentation is available here: https://landlock.io/linux-doc/landlock-v16/security/landlock/index.html This series can be applied on top of v5.7-rc1. This can be tested with CONFIG_SECURITY_LANDLOCK and CONFIG_SAMPLE_LANDLOCK. This patch series can be found in a Git repository here: https://github.com/landlock-lsm/linux/commits/landlock-v16 I would really appreciate constructive comments on this patch series. # Landlock LSM The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [2], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil.

[PATCH v5 0/4] KUnit-KASAN Integration

by David Gow

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources API" patchset [1] Changes from v4: - KASAN no longer will panic on errors if both panic_on_warn and kasan_multishot are enabled. - As a result, the KASAN tests will no-longer disable panic_on_warn. - This also means panic_on_warn no-longer needs to be exported. - The use of temporary "kasan_data" variables has been cleaned up somewhat. - A potential refcount/resource leak should multiple KASAN errors appear during an assertion was fixed. - Some wording changes to the KASAN test Kconfig entries. Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL(). Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [2] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable. Changes since v1: - Make use of Alan Maguire's suggestion to use his patch that allows static resources for integration instead of adding a new attribute to the kunit struct - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the test_kasan.c file since it seems this is the only place this will be used. - Integration relies on KUnit being builtin - copy_user_test has been separated into its own file since KUnit is unable to test these. This can be run as a module just as before, using CONFIG_TEST_KASAN_USER - The addition to the current task has been separated into its own patch as this is a significant enough change to be on its own.

[PATCH v8 kunit-next 0/4] kunit: add debugfs representation to show results

by Alan Maguire

When kunit tests are run on native (i.e. non-UML) environments, the results of test execution are often intermixed with dmesg output. This patch series attempts to solve this by providing a debugfs representation of the results of the last test run, available as /sys/kernel/debug/kunit/<testsuite>/results Changes since v7: - renamed KUNIT_INDENT[2] to KUNIT_SUBTEST_INDENT, KUNIT_SUBSUBTEST_INDENT and added more description to their definitions to clarify why they are defined as they are (Shuah) - defined KUNIT_SUBSUBTEST_INDENT directly as 8 spaces to avoid checkpatch error (Shuah) Changes since v6: - fixed regexp parsing in kunit_parser.py to ensure test results are read successfully with 4-space indentation (Brendan, patch 3) Changes since v5: - replaced undefined behaviour use of snprintf(buf, ..., buf) in kunit_log() with a function to append string to existing log (Frank, patch 1) - added clarification on log size limitations to documentation (Frank, patch 4) Changes since v4: - added suite-level log expectations to kunit log test (Brendan, patch 2) - added log expectations (of it being NULL) for case where CONFIG_KUNIT_DEBUGFS=n to kunit log test (patch 2) - added patch 3 which replaces subtest tab indentation with 4 space indentation as per TAP 14 spec (Frank, patch 3) Changes since v3: - added CONFIG_KUNIT_DEBUGFS to support conditional compilation of debugfs representation, including string logging (Frank, patch 1) - removed unneeded NULL check for test_case in kunit_suite_for_each_test_case() (Frank, patch 1) - added kunit log test to verify logging multiple strings works (Frank, patch 2) - rephrased description of results file (Frank, patch 3) Changes since v2: - updated kunit_status2str() to kunit_status_to_string() and made it static inline in include/kunit/test.h (Brendan) - added log string to struct kunit_suite and kunit_case, with log pointer in struct kunit pointing at the case log. This allows us to collect kunit_[err|info|warning]() messages at the same time as we printk() them. This solves for the most part the sharing of log messages between test execution and debugfs since we just print the suite log (which contains the test suite preamble) and the individual test logs. The only exception is the suite-level status, which we cannot store in the suite log as it would mean we'd print the suite and its status prior to the suite's results. (Brendan, patch 1) - dropped debugfs-based kunit run patch for now so as not to cause problems with tests currently under development (Brendan) - fixed doc issues with code block (Brendan, patch 3) Changes since v1: - trimmed unneeded include files in lib/kunit/debugfs.c (Greg) - renamed global debugfs functions to be prefixed with kunit_ (Greg) - removed error checking for debugfs operations (Greg) Alan Maguire (4): kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display kunit: add log test kunit: subtests should be indented 4 spaces according to TAP kunit: update documentation to describe debugfs representation Documentation/dev-tools/kunit/usage.rst | 14 +++ include/kunit/test.h | 63 ++++++++++++-- lib/kunit/Kconfig | 8 ++ lib/kunit/Makefile | 4 + lib/kunit/assert.c | 79 ++++++++--------- lib/kunit/debugfs.c | 116 +++++++++++++++++++++++++ lib/kunit/debugfs.h | 30 +++++++ lib/kunit/kunit-test.c | 44 +++++++++- lib/kunit/test.c | 148 +++++++++++++++++++++++++------- tools/testing/kunit/kunit_parser.py | 10 +-- 10 files changed, 430 insertions(+), 86 deletions(-) create mode 100644 lib/kunit/debugfs.c create mode 100644 lib/kunit/debugfs.h -- 1.8.3.1

[PATCH v5 0/5] kselftest: add fixture parameters

by Jakub Kicinski

Hi! Shuah please consider applying to the kselftest tree. This set is an attempt to make running tests for different sets of data easier. The direct motivation is the tls test which we'd like to run for TLS 1.2 and TLS 1.3, but currently there is no easy way to invoke the same tests with different parameters. Tested all users of kselftest_harness.h. v2: - don't run tests by fixture - don't pass params as an explicit argument v3: - go back to the orginal implementation with an extra parameter, and running by fixture (Kees); - add LIST_APPEND helper (Kees); - add a dot between fixture and param name (Kees); - rename the params to variants (Tim); v4: - whitespace fixes. v5 (Kees): - move a comment; - remove a temporary variable; - reword the commit message on patch 4. v1: https://lore.kernel.org/netdev/20200313031752.2332565-1-kuba@kernel.org/ v2: https://lore.kernel.org/netdev/20200314005501.2446494-1-kuba@kernel.org/ v3: https://lore.kernel.org/netdev/20200316225647.3129354-1-kuba@kernel.org/ v4: https://lore.kernel.org/netdev/20200317010419.3268916-1-kuba@kernel.org/ Jakub Kicinski (5): kselftest: factor out list manipulation to a helper kselftest: create fixture objects kselftest: run tests by fixture kselftest: add fixture variants selftests: tls: run all tests for TLS 1.2 and TLS 1.3 Documentation/dev-tools/kselftest.rst | 3 +- tools/testing/selftests/kselftest_harness.h | 234 +++++++++++++++----- tools/testing/selftests/net/tls.c | 93 ++------ 3 files changed, 202 insertions(+), 128 deletions(-) -- 2.25.1
