[PATCH] selftests/clone3: Skip new time namespace test when unsupported

by Mark Brown

Use a filter function to skip the time namespace test on systems with !CONFIG_TIME_NS. This reworks a fix originally done by Tiezhu Yang prior to the refactoring in 34dce23f7e40 ("selftests/clone3: Report descriptive test names"). The changelog from their fix explains the issue very clearly: When execute the following command to test clone3 under !CONFIG_TIME_NS: # make headers && cd tools/testing/selftests/clone3 && make && ./clone3 we can see the following error info: # [7538] Trying clone3() with flags 0x80 (size 0) # Invalid argument - Failed to create new process # [7538] clone3() with flags says: -22 expected 0 not ok 18 [7538] Result (-22) is different than expected (0) ... # Totals: pass:18 fail:1 xfail:0 xpass:0 skip:0 error:0 This is because if CONFIG_TIME_NS is not set, but the flag CLONE_NEWTIME (0x80) is used to clone a time namespace, it will return -EINVAL in copy_time_ns(). If kernel does not support CONFIG_TIME_NS, /proc/self/ns/time will be not exist, and then we should skip clone3() test with CLONE_NEWTIME. With this patch under !CONFIG_TIME_NS: # make headers && cd tools/testing/selftests/clone3 && make && ./clone3 ... # Time namespaces are not supported ok 18 # SKIP Skipping clone3() with CLONE_NEWTIME ... # Totals: pass:18 fail:0 xfail:0 xpass:0 skip:1 error:0 Fixes: 515bddf0ec41 ("selftests/clone3: test clone3 with CLONE_NEWTIME") Suggested-by: Thomas Gleixner <tglx(a)linutronix.de> Original-fix-from: Tiezhu Yang <yangtiezhu(a)loongson.cn> Signed-off-by: Mark Brown <broonie(a)kernel.org> --- tools/testing/selftests/clone3/clone3.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/tools/testing/selftests/clone3/clone3.c b/tools/testing/selftests/clone3/clone3.c index 9429d361059e..915846bc32cc 100644 --- a/tools/testing/selftests/clone3/clone3.c +++ b/tools/testing/selftests/clone3/clone3.c @@ -138,6 +138,16 @@ static bool not_root(void) return false; } +static bool timens_unsupported(void) +{ + if (access("/proc/self/ns/time", F_OK) == 0) { + ksft_print_msg("Time namespaces are not supported\n"); + return true; + } + + return false; +} + static size_t page_size_plus_8(void) { return getpagesize() + 8; @@ -282,6 +292,7 @@ static const struct test tests[] = { .size = 0, .expected = 0, .test_mode = CLONE3_ARGS_NO_TEST, + .filter = timens_unsupported, }, { .name = "exit signal (SIGCHLD) in flags", --- base-commit: 8d4099dd0727acfc8b0f644eacaf852f9d5dc649 change-id: 20231019-kselftest-clone3-time-ns-730b6f4187c7 Best regards, -- Mark Brown <broonie(a)kernel.org>

[PATCH v6 2/2] selftests/ftrace: Add new test case which checks non unique symbol

by Francis Laniel

If name_show() is non unique, this test will try to install a kprobe on this function which should fail returning EADDRNOTAVAIL. On kernel where name_show() is not unique, this test is skipped.

[PATCH v5 0/6] iommufd: Add nesting infrastructure (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series adds the cache invalidation path for the userspace to invalidate cache after modifying the stage-1 page table. This is based on the first part of nesting [1] Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks.

Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (1): iommu: Add cache_invalidate_user op Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (1): iommufd: Add IOMMU_HWPT_INVALIDATE drivers/iommu/iommufd/hw_pagetable.c | 35 ++++++++ drivers/iommu/iommufd/iommufd_private.h | 9 ++ drivers/iommu/iommufd/iommufd_test.h | 22 +++++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 69 +++++++++++++++ include/linux/iommu.h | 84 +++++++++++++++++++ include/uapi/linux/iommufd.h | 36 ++++++++ tools/testing/selftests/iommu/iommufd.c | 75 +++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 63 ++++++++++++++ 9 files changed, 396 insertions(+) -- 2.34.1
