[PATCH v1] lib/test_list: Follow existing pattern for a file name

by Andy Shevchenko

Test in lib/ either KUnit or not are named in the same pattern, i.e. test_*.c, except few ones. Rename list-test.c to test_list.c to follow this pattern. Note, current documentation doesn't specify any file name conventions, and we glad to stick with a current one in the subsystem.

[PATCH v21 00/12] Landlock LSM

by Mickaël Salaün

Hi, This new patch series mainly simplifies the syscalls thanks to Arnd Bergmann at LPC. The SLOC count is 1188 for security/landlock/ and 1673 for tools/testing/selftest/landlock/ . Test coverage for security/landlock/ is 95.4% of lines. The code not covered only deals with internal kernel errors (e.g. memory allocation) and race conditions. The compiled documentation is available here: https://landlock.io/linux-doc/landlock-v21/security/landlock/index.html This series can be applied on top of v5.9-rc8 . 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-v21 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 [1], 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. In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs [2].

[GIT PULL] Kselftest fixes update for Linux 5.10-rc1

by Shuah Khan

Hi Linus, Please pull the following Kselftest fixes update for Linux 5.10-rc1. This kselftest fixes update consists of a selftests harness fix to flush stdout before forking to avoid parent and child printing duplicates messages. This is evident when test output is redirected to a file. The second fix is a tools/ wide change to avoid comma separated statements from Joe Perches. This fix spans tools/lib, tools/power/cpupower, and selftests. diff is attached Please note that there is a conflict in tools/testing/selftests/vm/gup_test.c between commit: aa803771a80a ("tools: Avoid comma separated statements") from the kselftest-fixes tree and commit: 5c64830675a6 ("mm/gup_benchmark: rename to mm/gup_test") from the akpm tree. tools/testing/selftests/vm/gup_benchmark.c has been renamed in 5c64830675a6 from akpm tree.
