[PATCH] selftests: add headers_install to lib.mk

by Anders Roxell

If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.

[PATCH 0/4] selftests: rework RTC tests

by Alexandre Belloni

Hi, This series separates tests using the RTC devices between the one testing driver agnostic kernel facilities (timers) and the others that are testing device drivers and hardware. Then, rtctest is reworked to use the test harness and be much more robust. Skipping tests is now easier and tests will not block indefinitively. I'm planning to send more improvements later this cycle.

[PATCH v4 0/7] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. This patch makes a few of the kernel interfaces accept tagged user pointers. The kernel is already able to handle user faults with tagged pointers and has the untagged_addr macro, which this patchset reuses. We're not trying to cover all possible ways the kernel accepts user pointers in one patchset, so this one should be considered as a start. Thanks! [1] http://clang.llvm.org/docs/HardwareAssistedAddressSanitizerDesign.html Changes in v4: - Added a selftest for checking that passing tagged pointers to the kernel succeeds. - Rebased onto 81e97f013 (4.18-rc1+). Changes in v3: - Rebased onto e5c51f30 (4.17-rc6+). - Added linux-arch@ to the list of recipients. Changes in v2: - Rebased onto 2d618bdf (4.17-rc3+). - Removed excessive untagging in gup.c. - Removed untagging pointers returned from __uaccess_mask_ptr. Changes in v1: - Rebased onto 4.17-rc1. Changes in RFC v2: - Added "#ifndef untagged_addr..." fallback in linux/uaccess.h instead of defining it for each arch individually. - Updated Documentation/arm64/tagged-pointers.txt. - Dropped “mm, arm64: untag user addresses in memory syscalls”. - Rebased onto 3eb2ce82 (4.16-rc7).

[PATCH v13 00/24] selftests, powerpc, x86 : Memory Protection Keys

by Ram Pai

Memory protection keys enables an application to protect its address space from inadvertent access by its own code. This feature is now enabled on powerpc architecture and integrated in 4.16-rc1. The patches move the selftests to arch neutral directory and enhance their test coverage. Test ---- Verified for correctness on powerpc. Need help verifying on x86. Compiles on x86. History: ------- version 13: (1) Incorporated comments for Dave Hansen. (2) Added one more test for correct pkey-0 behavior. version 12: (1) fixed the offset of pkey field in the siginfo structure for x86_64 and powerpc. And tries to use the actual field if the headers have it defined. version 11: (1) fixed a deadlock in the ptrace testcase. version 10 and prior: (1) moved the testcase to arch neutral directory (2) split the changes into incremental patches.

[PATCH v9 0/7] Centralize and unify usage of preempt/irq tracepoints

by Joel Fernandes

From: "Joel Fernandes (Google)" <joel(a)joelfernandes.org> This is a posting of v9 preempt/irq tracepoint clean up series rebased onto v4.18-rc2. No changes in the series, just a rebase + repost. All patches have a Reviewed-by tags now from reviewers. This series has been well tested and is a simplification/refactoring of existing code, along with giving a speed-up for tracepoints using the rcu-idle API. With this our users will find it easier to use tools depending on existing preempt tracepoints since it simplifies the configuration for them. Future enhancements/fixes I am developing for preempt-off tracer will depend on these patches, so I suggest prioritizing these well reviewed and tested patches for that reason as well. Introduction to the series: The preempt/irq tracepoints exist but not everything in the kernel is using it whenever they need to be notified that a preempt disable/enable or an irq disable/enable has occurred. This makes things not work simultaneously (for example, only either lockdep or irqsoff trace-events can be used at a time). This is particularly painful to deal with, since turning on lockdep breaks tracers that install probes on IRQ events, such as the BCC atomic critical section tracer [1]. This constraint also makes it impossible to use synthetic events to trace irqsoff sections with lockdep simulataneously turned on. This series solves that, and also results in a nice clean up of relevant parts of the kernel. Several ifdefs are simpler, and the design is more unified and better. Also as a result of this, we also speeded performance all rcuidle tracepoints since their handling is simpler. [1] https://github.com/iovisor/bcc/blob/master/tools/criticalstat_example.txt v8->v9: - Small style changes to tracepoint code (Mathieu) - Minor style fix to use PTR_ERR_OR_ZERO (0-day bot) - Minor fix to test_atomic_sections to use unsigned long. - Added Namhyung's, Mathieu's Reviewed-by to some patches. - Added Acks from Matsami v7->v8: - Refactored irqsoff tracer probe defines (Namhyung) v6->v7: - Added a module to simulate an atomic section, a kselftest to load and and trigger it which verifies the preempt-tracer and this series. - Fixed a new warning after I rebased in early boot, this is because early_boot_irqs_disabled was set too early, I moved it after the lockdep initialization. - added back the softirq fix since it appears it wasn't picked up. - Ran Ingo's locking API selftest suite which are passing with this series. - Mathieu suggested ifdef'ing the tracepoint_synchronize_unregister function incase tracepoints aren't enabled, did that.

[PATCH net-next 00/13] mlxsw: Add resource scale tests

by Petr Machata

There are a number of tests that check features of the Linux networking stack. By running them on suitable interfaces, one can exercise the mlxsw offloading code. However none of these tests attempts to push mlxsw to the limits supported by the ASIC. As an additional wrinkle, the "limits supported by the ASIC" themselves may not be a set of fixed numbers, but rather depend on a profile that determines how the ASIC resources are allocated for different purposes. This patchset introduces several tests that verify capability of mlxsw to offload amounts of routes, flower rules, and mirroring sessions that match predicted ASIC capacity, at different configuration profiles. Additionally they verify that amounts exceeding the predicted capacity can *not* be offloaded. These are not generic tests, but ones that are tailored for mlxsw specifically. For that reason they are not added to net/forwarding selftests subdirectory, but rather to a newly-added drivers/net/mlxsw. Patches #1, #2 and #3 tweak the generic forwarding/lib.sh to support the new additions. In patches #4 and #5, new libraries for interfacing with devlink are introduced, first a generic one, then a Spectrum-specific one. In patch #6, a devlink resource test is introduced. Patches #7 and #8, #9 and #10, and #11 and #12 introduce three scale tests: router, flower and mirror-to-gretap. The first of each pair of patches introduces a generic portion of the test (mlxsw-specific), the second introduces a Spectrum-specific wrapper. Patch #13 then introduces a scale test driver that runs (possibly a subset of) the tests introduced by patches from previous paragraph.
