[PATCH] selftests: sysctl: return Kselftest Skip code for skipped tests

by Shuah Khan (Samsung OSG)

When sysctl test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Changed return code to kselftest skip code in skip error legs that check requirements and module probe test error leg. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.

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

by Joel Fernandes

From: "Joel Fernandes (Google)" <joel(a)joelfernandes.org> This is the next (hopefully close to final) revision of preempt/irq tracepoint centralization and unified usage across the kernel. This revision mostly has minor style corrections, reviewed-by tag additions and an improvement to the test module. All patches now have a Reviewed-by tag except for the kselftest script (patch 7/7). I have also now split out the softirq fix which really should go into an -rc cycle and is independent of this series (see [1]). 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 particular painful to deal with, since turning on lockdep breaks tracers that install probes on IRQ events, such as the BCC atomic critical section tracer [2]. This constraint also makes it not possible 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://lkml.org/lkml/2018/6/7/1135 [2] https://github.com/iovisor/bcc/pull/1801/ 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. 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 v6 0/2] sparc64: Add privileged ADI driver

by Tom Hromatka

ADI is a feature supported on SPARC M7 and newer processors to allow hardware to catch rogue accesses to memory. ADI is supported for data fetches only and not instruction fetches. An app can enable ADI on its data pages, set version tags on them and use versioned addresses to access the data pages. Upper bits of the address contain the version tag. On M7 processors, upper four bits (bits 63-60) contain the version tag. If a rogue app attempts to access ADI enabled data pages, its access is blocked and processor generates an exception. Please see Documentation/sparc/adi.txt for further details. This patchset implements a char driver to read/write ADI versions from privileged user space processes. Intended consumers are makedumpfile and crash. v6: * Addressed a few action items from greg k-h * Added Reviewed-by Greg Kroah-Hartman and Shuah Khan v5: * Fixed MODULE_LICENSE() for adi.c v4: * Fixed messed up subject lines. v3: * Really fixed the copyright headers to use SPDX GPL v2. Really. v2: * Simplified copyright headers * Completely reworked sparc64 selftests Makefiles. Used the android selftests Makefiles as an example * Added run.sh and drivers_test.sh to the sparc64 selftest directory. Used bpf/test_kmod.sh and the android selftests as examples * Minor cleanups in the selftest adi-test.c * Added calls to ksft_test_*() in the adi-test.c Tom Hromatka (2): char: sparc64: Add privileged ADI driver selftests: sparc64: char: Selftest for privileged ADI driver drivers/char/Kconfig | 12 + drivers/char/Makefile | 1 + drivers/char/adi.c | 239 +++++++ tools/testing/selftests/Makefile | 1 + tools/testing/selftests/sparc64/Makefile | 46 ++ tools/testing/selftests/sparc64/drivers/.gitignore | 1 + tools/testing/selftests/sparc64/drivers/Makefile | 15 + tools/testing/selftests/sparc64/drivers/adi-test.c | 721 +++++++++++++++++++++ .../selftests/sparc64/drivers/drivers_test.sh | 30 + tools/testing/selftests/sparc64/run.sh | 3 + 10 files changed, 1069 insertions(+) create mode 100644 drivers/char/adi.c create mode 100644 tools/testing/selftests/sparc64/Makefile create mode 100644 tools/testing/selftests/sparc64/drivers/.gitignore create mode 100644 tools/testing/selftests/sparc64/drivers/Makefile create mode 100644 tools/testing/selftests/sparc64/drivers/adi-test.c create mode 100755 tools/testing/selftests/sparc64/drivers/drivers_test.sh create mode 100755 tools/testing/selftests/sparc64/run.sh -- 2.15.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kselftest" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH net-next] selftests: forwarding: Fix importing dependent libraries

When libraries are sourced from elsewhere from the tree, such as the testing/selftests/drivers/net/mlxsw subdirectory, sourcing their own dependencies directly by name doesn't work. Thus running mirror_gre.sh from that subdirectory results in the following cascade of errors: ./../../../net/forwarding/mirror_gre_lib.sh: line 3: mirror_lib.sh: No such file or directory ./../../../net/forwarding/mirror_gre_topo_lib.sh: line 36: mirror_topo_lib.sh: No such file or directory ./../../../net/forwarding/mirror_gre_topo_lib.sh: line 80: mirror_topo_h1_create: command not found ./../../../net/forwarding/mirror_gre_topo_lib.sh: line 81: mirror_topo_h2_create: command not found ./../../../net/forwarding/mirror_gre_topo_lib.sh: line 40: mirror_topo_h3_create: command not found [...] Fix by relying on $relative_path, set up by lib.sh, which should be imported by the test in question anyway, and source the file using relative path appropriate for the subdirectory.
