[PATCH] kselftest: mqueue: increase timeout

by Vijai Kumar K

The default kselftest timeout is 45 seconds per test after which run_kselftest marks the test case as failure. Some mqueue perf tests take more than 100s to complete; especially in qemu environment. Increase the timeout to 180 seconds for mqueue.

[PATCH MANUALSEL 5.17 3/3] KVM: selftests: Restrict test region to 48-bit physical addresses when using nested

by Sasha Levin

From: David Matlack <dmatlack(a)google.com> [ Upstream commit e0f3f46e42064a51573914766897b4ab95d943e3 ] The selftests nested code only supports 4-level paging at the moment. This means it cannot map nested guest physical addresses with more than 48 bits. Allow perf_test_util nested mode to work on hosts with more than 48 physical addresses by restricting the guest test region to 48-bits. While here, opportunistically fix an off-by-one error when dealing with vm_get_max_gfn(). perf_test_util.c was treating this as the maximum number of GFNs, rather than the maximum allowed GFN. This didn't result in any correctness issues, but it did end up shifting the test region down slightly when using huge pages.

[PATCH] selftests/vm: Only run the 128TB boundary test if 5-level paging is enabled

by Adam Sindelar

The test va_128TBswitch.c expects to be able to pass mmap an address hint and length that cross the address 1<<47. This is not possible without 5-level page tables, so the test fails. The test is already only run on 64-bit powerpc and x86 archs, but this patch adds an additional check that skips the test if PG_TABLE_LEVELS < 5. There is precedent for checking /proc/config.gz in selftests, e.g. in selftests/firmware.

[PATCH 0/5] Rework KUnit test execution in modules

by David Gow

This patch series makes two changes to how KUnit test suites are stored and executed: - The .kunit_test_suites section is now used for tests in modules (in lieu of a module_init funciton), as well as for built-in tests. The module loader will now trigger test execution. This frees up the module_init function for other uses. - Instead of storing an array of arrays of suites, have the kunit_test_suite() and kunit_test_suites() macros append to one global (or per-module) list of test suites. This removes a needless layer of indirection. The upshot of this is that it should now be possible to use the kunit_test_suite() and kunit_test_suites() macros to register test suites even from within modules which otherwise had module_init functions. This was proving to be quite a common issue, resulting in several modules calling into KUnit's private suite execution functions to run their tests (often introducing incompatibilities with the KUnit tooling). This series also fixes the thunderbolt, nitro_enclaves, and sdhci-of-aspeed tests to use kunit_test_suite() now that it works. Huge thanks to Jeremy Kerr, who designed and implemented the module loader changes, and to Daniel Latypov for pushing the simplification of the nested arrays in .kunit_test_suites. I've tested this series both with builtin tests, and with modules on x86_64, but there's always the possibility that there's something subtle and nasty on another architecture, so please test!

[PATCH v2 net] ipv4: fix bind address validity regression tests

by Riccardo Paolo Bestetti

Commit 8ff978b8b222 ("ipv4/raw: support binding to nonlocal addresses") introduces support for binding to nonlocal addresses, as well as some basic test coverage for some of the related cases. Commit b4a028c4d031 ("ipv4: ping: fix bind address validity check") fixes a regression which incorrectly removed some checks for bind address validation. In addition, it introduces regression tests for those specific checks. However, those regression tests are defective, in that they perform the tests using an incorrect combination of bind flags. As a result, those tests fail when they should succeed. This commit introduces additional regression tests for nonlocal binding and fixes the defective regression tests. It also introduces new set_sysctl calls for the ipv4_bind test group, as to perform the ICMP binding tests it is necessary to allow ICMP socket creation by setting the net.ipv4.ping_group_range knob.
