[PATCH] selftests/nolibc: only run constructor tests on nolibc

by Thomas Weißschuh

The nolibc testsuite can be run against other libcs to test for interoperability. Some aspects of the constructor execution are not standardized and musl does not provide all tested feature, for one it does not provide arguments to the constructors, anymore? Skip the constructor tests on non-nolibc configurations.

[PATCH v6 0/3] Add support for the Idle HLT intercept feature

by Manali Shukla

The upcoming new Idle HLT Intercept feature allows for the HLT instruction execution by a vCPU to be intercepted by the hypervisor only if there are no pending V_INTR and V_NMI events for the vCPU. When the vCPU is expected to service the pending V_INTR and V_NMI events, the Idle HLT intercept won’t trigger. The feature allows the hypervisor to determine if the vCPU is actually idle and reduces wasteful VMEXITs. The Idle HLT intercept feature is used for enlightened guests who wish to securely handle the events. When an enlightened guest does a HLT while an interrupt is pending, hypervisor will not have a way to figure out whether the guest needs to be re-entered or not. The Idle HLT intercept feature allows the HLT execution only if there are no pending V_INTR and V_NMI events. Presence of the Idle HLT Intercept feature is indicated via CPUID function Fn8000_000A_EDX[30]. Document for the Idle HLT intercept feature is available at [1]. This series is based on kvm-x86/next (eb723766b103) + [2]. Testing Done: - Tested the functionality for the Idle HLT intercept feature using selftest ipi_hlt_test. - Tested on normal, SEV, SEV-ES, SEV-SNP guest for the Idle HLT intercept functionality. - Tested the Idle HLT intercept functionality on nested guest. v5 -> v6 - Incorporated Neeraj's review comments on selftest. v4 -> v5 - Incorporated Sean's review comments on nested Idle HLT intercept support. - Make svm_idle_hlt_test independent of the Idle HLT to run on all hardware. v3 -> v4 - Drop the patches to add vcpu_get_stat() into a new series [2]. - Added nested Idle HLT intercept support. v2 -> v3 - Incorporated Andrew's suggestion to structure vcpu_stat_types in a way that each architecture can share the generic types and also provide its own. v1 -> v2 - Did changes in svm_idle_hlt_test based on the review comments from Sean. - Added an enum based approach to get binary stats in vcpu_get_stat() which doesn't use string to get stat data based on the comments from Sean. - Added safe_halt() and cli() helpers based on the comments from Sean.

[PATCH v2 0/9] selftests/mm: Some cleanups from trying to run them

by Brendan Jackman

I never had much luck running mm selftests so I spent a couple of hours digging into why. Looks like most of the reason is missing SKIP checks, so this series is just adding a bunch of those that I found. I did not do anything like all of them, just the ones I spotted in gup_longterm, gup_test, mmap, userfaultfd and memfd_secret. It's a bit unfortunate to have to skip those tests when ftruncate() fails, but I don't have time to dig deep enough into it to actually make them pass - I observed these issues on both 9p and virtiofs. Probably it requires digging into the filesystem implementation (An alternative might just be to mount a tmpfs in the test script). I am also seeing some failures to allocate hugetlb pages in uffd-mp-mremap that I have not had time to fully understand, you can see those here: https://gist.github.com/bjackman/af74c3a6e60975e6ff0d760cba1e05d2#file-user… Signed-off-by: Brendan Jackman <jackmanb(a)google.com> --- Changes in v2 (Thanks to Dev for the reviews): - Improve and cleanup some error messages - Add some extra SKIPs - Fix misnaming of nr_cpus variable in uffd tests - Link to v1: https://lore.kernel.org/r/20250220-mm-selftests-v1-0-9bbf57d64463@google.com --- Brendan Jackman (9): selftests/mm: Report errno when things fail in gup_longterm selftests/mm: Fix assumption that sudo is present selftests/mm: Skip uffd-stress if userfaultfd not available selftests/mm: Skip uffd-wp-mremap if userfaultfd not available selftests/mm/uffd: Rename nr_cpus -> nr_threads selftests/mm: Print some details when uffd-stress gets bad params selftests/mm: Don't fail uffd-stress if too many CPUs selftests/mm: Skip map_populate on weird filesystems selftests/mm: Skip gup_longerm tests on weird filesystems tools/testing/selftests/mm/gup_longterm.c | 45 ++++++++++++++++++---------- tools/testing/selftests/mm/map_populate.c | 7 +++++ tools/testing/selftests/mm/run_vmtests.sh | 22 +++++++++++--- tools/testing/selftests/mm/uffd-common.c | 8 ++--- tools/testing/selftests/mm/uffd-common.h | 2 +- tools/testing/selftests/mm/uffd-stress.c | 42 ++++++++++++++++---------- tools/testing/selftests/mm/uffd-unit-tests.c | 2 +- tools/testing/selftests/mm/uffd-wp-mremap.c | 5 +++- 8 files changed, 90 insertions(+), 43 deletions(-) --- base-commit: a3daad8215143340c0870c5489e599fd059037e9 change-id: 20250220-mm-selftests-2d7d0542face Best regards, -- Brendan Jackman <jackmanb(a)google.com>

[PATCH bpf-next 00/10] selftests/bpf: Migrate test_tunnel.sh to test_progs

by Bastien Curutchet (eBPF Foundation)

Hi all, This patch series continues the work to migrate the *.sh tests into prog_tests framework. The test_tunnel.sh script has already been partly migrated to test_progs in prog_tests/test_tunnel.c so I add my work to it. PATCH 1 & 2 create some helpers to avoid code duplication and ease the migration in the following patches. PATCH 3 to 9 migrate the tests of gre, ip6gre, erspan, ip6erspan, geneve, ip6geneve and ip6tnl tunnels. PATCH 10 removes test_tunnel.sh Signed-off-by: Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com> --- Bastien Curutchet (eBPF Foundation) (10): selftests/bpf: test_tunnel: Add generic_attach* helpers selftests/bpf: test_tunnel: Add ping helpers selftests/bpf: test_tunnel: Move gre tunnel test to test_progs selftests/bpf: test_tunnel: Move ip6gre tunnel test to test_progs selftests/bpf: test_tunnel: Move erspan tunnel tests to test_progs selftests/bpf: test_tunnel: Move ip6erspan tunnel test to test_progs selftests/bpf: test_tunnel: Move geneve tunnel test to test_progs selftests/bpf: test_tunnel: Move ip6geneve tunnel test to test_progs selftests/bpf: test_tunnel: Move ip6tnl tunnel tests to test_progs selftests/bpf: test_tunnel: Remove test_tunnel.sh tools/testing/selftests/bpf/Makefile | 1 - .../testing/selftests/bpf/prog_tests/test_tunnel.c | 627 +++++++++++++++++--- tools/testing/selftests/bpf/test_tunnel.sh | 645 --------------------- 3 files changed, 532 insertions(+), 741 deletions(-) --- base-commit: 16566afa71143757b49fc4b2a331639f487d105a change-id: 20250131-tunnels-59b641ea3f10 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com>
