[RFC PATCH 00/15] rseq uapi and selftest updates

by Mathieu Desnoyers

Update the rseq selftests to adapt to the userspace ABI chosen by glibc (will be released in February 2022). Provide a fallback implementation to work with older glibc as well. Remove broken 32-bit little/big endian accessor fields in rseq uapi. Integrate various fixes gathered from librseq, including work-around for known gcc and clang compiler bugs with asm goto. The uplift to glibc's userspace ABI means we can now use %fs/%gs segment selectors directly in the inline assembler for accesses to the rseq thread area on x86. Feedback is welcome, Thanks, Mathieu Mathieu Desnoyers (15): selftests/rseq: introduce own copy of rseq uapi header rseq: Remove broken uapi field layout on 32-bit little endian selftests/rseq: Remove useless assignment to cpu variable selftests/rseq: Remove volatile from __rseq_abi selftests/rseq: Introduce rseq_get_abi() helper selftests/rseq: Introduce thread pointer getters selftests/rseq: Uplift rseq selftests for compatibility with glibc-2.35 selftests/rseq: Fix ppc32: wrong rseq_cs 32-bit field pointer on big endian selftests/rseq: Fix ppc32 missing instruction selection "u" and "x" for load/store selftests/rseq: Fix ppc32 offsets by using long rather than off_t selftests/rseq: Fix warnings about #if checks of undefined tokens selftests/rseq: Remove arm/mips asm goto compiler work-around selftests/rseq: Fix: work-around asm goto compiler bugs selftests/rseq: x86-64: use %fs segment selector for accessing rseq thread area selftests/rseq: x86-32: use %gs segment selector for accessing rseq thread area include/uapi/linux/rseq.h | 17 +- tools/testing/selftests/rseq/Makefile | 2 +- .../selftests/rseq/basic_percpu_ops_test.c | 2 +- tools/testing/selftests/rseq/compiler.h | 30 +++ tools/testing/selftests/rseq/param_test.c | 8 +- tools/testing/selftests/rseq/rseq-abi.h | 151 +++++++++++++ tools/testing/selftests/rseq/rseq-arm.h | 110 +++++----- tools/testing/selftests/rseq/rseq-arm64.h | 79 +++++-- .../rseq/rseq-generic-thread-pointer.h | 25 +++ tools/testing/selftests/rseq/rseq-mips.h | 71 ++----- .../selftests/rseq/rseq-ppc-thread-pointer.h | 30 +++ tools/testing/selftests/rseq/rseq-ppc.h | 128 +++++++---- tools/testing/selftests/rseq/rseq-s390.h | 55 +++-- tools/testing/selftests/rseq/rseq-skip.h | 2 +- .../selftests/rseq/rseq-thread-pointer.h | 19 ++ .../selftests/rseq/rseq-x86-thread-pointer.h | 40 ++++ tools/testing/selftests/rseq/rseq-x86.h | 200 ++++++++++++------ tools/testing/selftests/rseq/rseq.c | 163 +++++++------- tools/testing/selftests/rseq/rseq.h | 29 ++- 19 files changed, 793 insertions(+), 368 deletions(-) create mode 100644 tools/testing/selftests/rseq/compiler.h create mode 100644 tools/testing/selftests/rseq/rseq-abi.h create mode 100644 tools/testing/selftests/rseq/rseq-generic-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-ppc-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-thread-pointer.h create mode 100644 tools/testing/selftests/rseq/rseq-x86-thread-pointer.h -- 2.17.1

[PATCH 1/3] selftests/zram: Remove obsolete max_comp_streams interface

Since kernel commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram has switched to per-cpu streams.

[PATCH v4] selftests/kselftest/runner.sh: Pass optional command parameters in environment

Some testcases allow for optional commandline parameters but as of now there is now way to provide such arguments to the runner script. Add support to retrieve such optional command parameters fron environment variables named so as to include the all-uppercase test executable name, sanitized substituting any non-acceptable varname characters with "_", following the pattern: KSELFTEST_<UPPERCASE_SANITIZED_TEST_NAME>_ARGS="options" Optional command parameters support is not available if 'tr' is not installed on the test system.

[PATCH 0/3] kunit: further reduce stack usage of asserts

by Daniel Latypov

If the compiler doesn't optimize them away, each kunit assertion (use of KUNIT_EXPECT_EQ, etc.) can use 88 bytes of stack space in the worst and most common case. This has led to compiler warnings for certain configs + arches [1]. This series builds upon [2] which cut down kunit_assert from 48 => 24 bytes, but only reduced kunit_binary_assert (the most common one) from 88 => 48. Now we have kunit_assert = 8 and kunit_binary_assert = 32. The cost is we need to pass around another parameter to some functions (struct va_format *), and we introduce a new type (sturct kunit_binary_assert_text) for holding the textual representation of the KUNIT_EXPECT_EQ arguments. Note: it's possible to get kunit_assert = 0 and kunit_binary_assert = 24 by removing the `format` function pointer field from kunit_assert. I think it's an improvement, but others might think that readability suffers from doing so, so I'm leaving that off from this series. Meta: this series applies on top of 5.17-rc1 + [2] and [3]. That should be available at in Shuah's kunit branch [4], but my version of git is constantly segfaulting, so I can't try and rebase to verify.

[PATCH v3] kselftest: kvm/arm64: Skip tests if we can't create a vgic-v3

by Mark Brown

The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output. Signed-off-by: Mark Brown <broonie(a)kernel.org> --- v3: - Use custom print_skip() helper. - Use internal version of _kvm_create_device. v2: - The test for being able to create the GIC doesn't actually instantiate it, add a call doing so in that case. tools/testing/selftests/kvm/aarch64/arch_timer.c | 7 ++++++- tools/testing/selftests/kvm/aarch64/vgic_irq.c | 4 ++++ tools/testing/selftests/kvm/lib/aarch64/vgic.c | 4 +++- 3 files changed, 13 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/kvm/aarch64/arch_timer.c b/tools/testing/selftests/kvm/aarch64/arch_timer.c index 9ad38bd360a4..b08d30bf71c5 100644 --- a/tools/testing/selftests/kvm/aarch64/arch_timer.c +++ b/tools/testing/selftests/kvm/aarch64/arch_timer.c @@ -366,6 +366,7 @@ static struct kvm_vm *test_vm_create(void) { struct kvm_vm *vm; unsigned int i; + int ret; int nr_vcpus = test_args.nr_vcpus; vm = vm_create_default_with_vcpus(nr_vcpus, 0, 0, guest_code, NULL); @@ -382,7 +383,11 @@ static struct kvm_vm *test_vm_create(void) ucall_init(vm, NULL); test_init_timer_irq(vm); - vgic_v3_setup(vm, nr_vcpus, 64, GICD_BASE_GPA, GICR_BASE_GPA); + ret = vgic_v3_setup(vm, nr_vcpus, 64, GICD_BASE_GPA, GICR_BASE_GPA); + if (ret < 0) { + print_skip("Failed to create vgic-v3"); + exit(KSFT_SKIP); + } /* Make all the test's cmdline args visible to the guest */ sync_global_to_guest(vm, test_args); diff --git a/tools/testing/selftests/kvm/aarch64/vgic_irq.c b/tools/testing/selftests/kvm/aarch64/vgic_irq.c index e6c7d7f8fbd1..7eca97799917 100644 --- a/tools/testing/selftests/kvm/aarch64/vgic_irq.c +++ b/tools/testing/selftests/kvm/aarch64/vgic_irq.c @@ -761,6 +761,10 @@ static void test_vgic(uint32_t nr_irqs, bool level_sensitive, bool eoi_split) gic_fd = vgic_v3_setup(vm, 1, nr_irqs, GICD_BASE_GPA, GICR_BASE_GPA); + if (gic_fd < 0) { + print_skip("Failed to create vgic-v3, skipping"); + exit(KSFT_SKIP); + } vm_install_exception_handler(vm, VECTOR_IRQ_CURRENT, guest_irq_handlers[args.eoi_split][args.level_sensitive]); diff --git a/tools/testing/selftests/kvm/lib/aarch64/vgic.c b/tools/testing/selftests/kvm/lib/aarch64/vgic.c index b3a0fca0d780..f5cd0c536d85 100644 --- a/tools/testing/selftests/kvm/lib/aarch64/vgic.c +++ b/tools/testing/selftests/kvm/lib/aarch64/vgic.c @@ -52,7 +52,9 @@ int vgic_v3_setup(struct kvm_vm *vm, unsigned int nr_vcpus, uint32_t nr_irqs, nr_vcpus, nr_vcpus_created); /* Distributor setup */ - gic_fd = kvm_create_device(vm, KVM_DEV_TYPE_ARM_VGIC_V3, false); + if (_kvm_create_device(vm, KVM_DEV_TYPE_ARM_VGIC_V3, + false, &gic_fd) != 0) + return -1; kvm_device_access(gic_fd, KVM_DEV_ARM_VGIC_GRP_NR_IRQS, 0, &nr_irqs, true); -- 2.30.2

[PATCH 0/2] sigaltstack: return only one flag

by Stas Sergeev

Currently sigaltstack() can return multiple flags, for example SS_DISABLE|SS_AUTODISARM. This confuses libraries (including asan runtime) and contradicts the man page. Patch 1 fixes this problem by ignoring any flag passed with SS_DISABLE. Patch 2 adds a test-case for that scenario. Signed-off-by: Stas Sergeev <stsp2(a)yandex.ru> CC: "Eric W.
