[PATCH] lib: Add Dhrystone benchmark test

by Geert Uytterhoeven

When working on SoC bring-up, (a full) userspace may not be available, making it hard to benchmark the CPU performance of the system under development. Still, one may want to have a rough idea of the (relative) performance of one or more CPU cores, especially when working on e.g. the clock driver that controls the CPU core clock(s). Hence make the classical Dhrystone 2.1 benchmark available as a Linux kernel test module, based on[1]. When built-in, this benchmark can be run without any userspace present. Parallel runs (run on multiple CPU cores) are supported, just kick the "run" file multiple times. Note that the actual figures depend on the configuration options that control compiler optimization (e.g. CONFIG_CC_OPTIMIZE_FOR_SIZE vs. CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE), and on the compiler options used when building the kernel in general. Hence numbers may differ from those obtained by running similar benchmarks in userspace. [1] https://github.com/qris/dhrystone-deb.git Signed-off-by: Geert Uytterhoeven <geert+renesas(a)glider.be> --- This has been used to validate secondary CPU bringup and cpufreq support on the R-Car S4-8 and V4H SoCs. Changes compared to the original Dhrystone 2.1 C version: - Remove trailing whitespace - Remove unused NOSTRUCTASSIGN - Remove unused NOENUM(S) - Remove unused REG - Use ktime for time measurements - Use kzalloc() for memory allocation - Remove definition and use of Null - Remove definitions of true and false - Use pr_info() for printing - Replace sscanf() use by parameter n - Replace userspace includes by kernel includes - Replace K&R by ANSI function declarations - Move/add external/forward declarations to dhry.h - Reshuffle functions to avoid forward declarations - Make local symbols static - Add kernel module wrapper - Let dhry() return the number of dhrystones - Add automatic iteration handling - Whitespace and indentation fixes - Fix braces and related indentation - Remove parentheses from return values - Reduce printed output - Use %px to print pointers - Verify results automatically - Make time measurement variables local - Add SPDX-License tags - Add Dhrystone benchmark test to config/build system An unsquashed version can be found at https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git/l… --- lib/Kconfig.debug | 35 +++++ lib/Makefile | 2 + lib/dhry.h | 358 ++++++++++++++++++++++++++++++++++++++++++++++ lib/dhry_1.c | 283 ++++++++++++++++++++++++++++++++++++ lib/dhry_2.c | 175 ++++++++++++++++++++++ lib/dhry_run.c | 85 +++++++++++ 6 files changed, 938 insertions(+) create mode 100644 lib/dhry.h create mode 100644 lib/dhry_1.c create mode 100644 lib/dhry_2.c create mode 100644 lib/dhry_run.c diff --git a/lib/Kconfig.debug b/lib/Kconfig.debug index a1b56cde3f843fbc..9e834f8cd6d163db 100644 --- a/lib/Kconfig.debug +++ b/lib/Kconfig.debug @@ -2036,6 +2036,41 @@ menuconfig RUNTIME_TESTING_MENU if RUNTIME_TESTING_MENU +config TEST_DHRY + tristate "Dhrystone benchmark test" + help + Enable this to include the Dhrystone 2.1 benchmark.

In the past, the C versions distributed + * by Rick Richardson (Version 1.1) and by Reinhold Weicker + * had small (though not significant) differences. + * + * 2) As far as it is possible without changes to the Dhrystone + * statistics, optimizing compilers should be prevented from + * removing significant statements. + * + * This C version has been developed in cooperation with + * Rick Richardson (Tinton Falls, NJ), it incorporates many + * ideas from the "Version 1.1" distributed previously by + * him over the UNIX network Usenet. + * I also thank Chaim Benedelac (National Semiconductor), + * David Ditzel (SUN), Earl Killian and John Mashey (MIPS), + * Alan Smith and Rafael Saavedra-Barrera (UC at Berkeley) + * for their help with comments on earlier versions of the + * benchmark. + * + * Changes: In the initialization part, this version follows mostly + * Rick Richardson's version distributed via Usenet, not the + * version distributed earlier via floppy disk by Reinhold Weicker. + * As a concession to older compilers, names have been made + * unique within the first 8 characters. + * Inside the measurement loop, this version follows the + * version previously distributed by Reinhold Weicker. + * + * At several places in the benchmark, code has been added, + * but within the measurement loop only in branches that + * are not executed. The intention is that optimizing compilers + * should be prevented from moving code out of the measurement + * loop, or from removing code altogether. Since the statements + * that are executed within the measurement loop have NOT been + * changed, the numbers defining the "Dhrystone distribution" + * (distribution of statements, operand types and locality) + * still hold. Except for sophisticated optimizing compilers, + * execution times for this version should be the same as + * for previous versions. + * + * Since it has proven difficult to subtract the time for the + * measurement loop overhead in a correct way, the loop check + * has been made a part of the benchmark. This does have + * an impact - though a very minor one - on the distribution + * statistics which have been updated for this version. + * + * All changes within the measurement loop are described + * and discussed in the companion paper "Rationale for + * Dhrystone version 2". + * + * Because of the self-imposed limitation that the order and + * distribution of the executed statements should not be + * changed, there are still cases where optimizing compilers + * may not generate code for some statements. To a certain + * degree, this is unavoidable for small synthetic benchmarks. + * Users of the benchmark are advised to check code listings + * whether code is generated for all statements of Dhrystone. + * + * Version 2.1 is identical to version 2.0 distributed via + * the UNIX network Usenet in March 1988 except that it corrects + * some minor deficiencies that were found by users of version 2.0. + * The only change within the measurement loop is that a + * non-executed "else" part was added to the "if" statement in + * Func_3, and a non-executed "else" part removed from Proc_3. + * + *************************************************************************** + * + * Compilation model and measurement (IMPORTANT): + * + * This C version of Dhrystone consists of three files: + * - dhry.h (this file, containing global definitions and comments) + * - dhry_1.c (containing the code corresponding to Ada package Pack_1) + * - dhry_2.c (containing the code corresponding to Ada package Pack_2) + * + * The following "ground rules" apply for measurements: + * - Separate compilation + * - No procedure merging + * - Otherwise, compiler optimizations are allowed but should be indicated + * - Default results are those without register declarations + * See the companion paper "Rationale for Dhrystone Version 2" for a more + * detailed discussion of these ground rules. + * + * For 16-Bit processors (e.g. 80186, 80286), times for all compilation + * models ("small", "medium", "large" etc.) should be given if possible, + * together with a definition of these models for the compiler system used. + * + ************************************************************************** + * + * Dhrystone (C version) statistics: + * + * [Comment from the first distribution, updated for version 2. + * Note that because of language differences, the numbers are slightly + * different from the Ada version.] + * + * The following program contains statements of a high level programming + * language (here: C) in a distribution considered representative: + * + * assignments 52 (51.0 %) + * control statements 33 (32.4 %) + * procedure, function calls 17 (16.7 %) + * + * 103 statements are dynamically executed.

[PATCH v2 5/7] KVM: arm64: selftests: Don't identity map the ucall MMIO hole

by Oliver Upton

Currently the ucall MMIO hole is placed immediately after slot0, which is a relatively safe address in the PA space. However, it is possible that the same address has already been used for something else (like the guest program image) in the VA space. At least in my own testing, building the vgic_irq test with clang leads to the MMIO hole appearing underneath gicv3_ops. Stop identity mapping the MMIO hole and instead find an unused VA to map to it. Yet another subtle detail of the KVM selftests library is that virt_pg_map() does not update vm->vpages_mapped. Switch over to virt_map() instead to guarantee that the chosen VA isn't to something else.

[PATCH v2 2/7] KVM: selftests: Setup ucall after loading program into guest memory

by Oliver Upton

The new ucall infrastructure needs to update a couple of guest globals to pass through the ucall MMIO addr and pool of ucall structs.

[PATCH] selftests/x86/msr: Add MSR restore test for suspend cycle

by Pawan Gupta

There are certain security related MSRs that must be restored after a suspend cycle. There have been quite a few fixes done to restore these MSRs: commit e2a1256b17b1 ("x86/speculation: Restore speculation related MSRs during S3 resume") commit 50bcceb7724e ("x86/pm: Add enumeration check before spec MSRs save/restore setup") commit 66065157420c ("x86/bugs: Make sure MSR_SPEC_CTRL is updated properly upon resume from S3") commit 2632daebafd0 ("x86/cpu: Restore AMD's DE_CFG MSR after resume") commit 73924ec4d560 ("x86/pm: Save the MSR validity status at context setup") commit f9e14dbbd454 ("x86/cpu: Load microcode during restore_processor_state()") In order to catch regressions early add a selftest that keeps a copy of below MSRs for all CPUs: MSR_IA32_SPEC_CTRL MSR_IA32_TSX_CTRL MSR_TSX_FORCE_ABORT MSR_IA32_MCU_OPT_CTRL MSR_AMD64_LS_CFG MSR_AMD64_DE_CFG The test does a suspend/resume and reports failure if the MSRs are not restored to the value before suspend.

[V1 PATCH 0/6] selftests: KVM: selftests for fd-based private memory

by Vishal Annapurve

This series implements selftests targeting the feature floated by Chao via: https://lore.kernel.org/linux-mm/20221109041358.GA118963@chaop.bj.intel.com… Below changes aim to test the fd based approach for guest private memory in context of normal (non-confidential) VMs executing on non-confidential platforms. private_mem_test.c file adds selftest to access private memory from the guest via private/shared accesses and checking if the contents can be leaked to/accessed by vmm via shared memory view before/after conversions. Updates in V1 (Compared to RFC v3 patches): 1) Incorporated suggestions from Sean around simplifying KVM changes 2) Addressed comments from Sean 3) Added private mem test with shared memory backed by 2MB hugepages. RFC v3 series: https://lore.kernel.org/lkml/20220819174659.2427983-1-vannapurve@google.com… This series has dependency on following patches: 1) V9 series patches from Chao mentioned above.

[PATCH 3/4] KVM: arm64: selftests: Align VA space allocator with TTBR0

by Oliver Upton

An interesting feature of the Arm architecture is that the stage-1 MMU supports two distinct VA regions, controlled by TTBR{0,1}_EL1. As KVM selftests on arm64 only uses TTBR0_EL1, the VA space is constrained to [0, 2^(va_bits-1)). This is different from other architectures that allow for addressing low and high regions of the VA space from a single page table. KVM selftests' VA space allocator presumes the valid address range is split between low and high memory based the MSB, which of course is a poor match for arm64's TTBR0 region. Allow architectures to override the default VA space layout. Make use of the override to align vpages_valid with the behavior of TTBR0 on arm64.

[PATCH] selftests/tpm2: Split async tests call to separate shell script runner

by Nícolas F. R. A. Prado

When the async test case was introduced, despite being a completely independent test case, the command to run it was added to the same shell script as the smoke test case. Since a shell script implicitly returns the error code from the last run command, this effectively caused the script to only return as error code the result from the async test case, hiding the smoke test result (which could then only be seen from the python unittest logs). Move the async test case call to its own shell script runner to avoid the aforementioned issue. This also makes the output clearer to read, since each kselftest KTAP result now matches with one python unittest report. While at it, also make it so the async test case is skipped if /dev/tpmrm0 doesn't exist, since commit 8335adb8f9d3 ("selftests: tpm: add async space test with noneexisting handle") added a test that relies on it.

[PATCH v14 00/39] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - SME is currently not supported for KVM guests, this will be done as a followup series. A host system can use SME and run KVM guests but SME is not available in the guests. - The KVM host support is done in a very simplistic way, were anyone to attempt to use it in production there would be performance impacts on hosts with SME support. As part of this we also add enumeration of fine grained traps. - There is not currently ptrace or signal support TPIDR2, this will be done as a followup series. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. v14: - Rebase onto v5.18-rc3. v13: - Preserve ZA in both parent and child on clone() and add a test case for this. - Fix EFI integration for FA64. - Minor tweaks to the ABI document following Catlain's review. - Add and make use of thread_get_cur_vl() helper. - Fix some issues with SVE/FPSIMD register type moves in streaming SVE ptrace. - Typo fixes. - Roll in separately posted series extending ptrace coverage in kselftest for better integrated testing of the series. v12: - Fix some typos in the ABI document. - Print a message when we skip a vector length in the signal tests. - Add note of earliest toolchain versions with SME to manual encodings for future reference now that's landed. - Drop reference to PCS in sme.rst, it's not referenced and one of the links was broken. - Encode smstop and smstart as sysregs in the kernel. - Don't redundantly flush the SVE register state when loading FPSIMD state with SME enabled for the task, the architecture will do this for us. - Introduce and use task_get_cur_vl() to get the vector length for the currently active SVE registers. - Fix support for !FA64 mode in signal and syscall tests. - Simplify instruction sequence for ssve_regs signal test. - Actually include the ZA signal test in the patch set. v11: - Rebase onto v5.17-rc3. - Provide a sme-inst.h to collect manual encodings in kselftest. v10: - Actually do the rebase of fixups from the previous version into relevant patches. v9: - Remove defensive programming around IS_ENABLED() and FGT in KVM code. - Fix naming of TPIDR2 FGT register bit. - Add patches making handling of floating point register bits more consistent (also sent as separate series). - Drop now unused enumeration of fine grained traps. v8: - Rebase onto v5.17-rc1. - Support interoperation with KVM, SME is disabled for KVM guests with minimal handling for cleaning up SME state when entering and leaving the guest. - Document and implement that signal handlers are invoked with ZA and streaming mode disabled. - Use the RDSVL instruction introduced in EAC2 of the architecture to obtain the streaming mode vector length during enumeration, ZA state loading/saving and in test programs. - Store a pointer to SVCR in fpsimd_last_state and use it in fpsimd_save() for interoperation with KVM. - Add a test case sme_trap_no_sm checking that we generate a SIGILL when using an instruction that requires streaming mode without enabling it. - Add basic ZA context form validation to testcases helper library. - Move signal tests over to validating streaming VL from ZA information. - Pulled in patch removing ARRAY_SIZE() so that kselftest builds cleanly and to avoid trivial conflicts. v7: - Rebase onto v5.16-rc3. - Reduce indentation when supporting custom triggers for signal tests as suggested by Catalin. - Change to specifying a width for all CPU features rather than adding single bit specific infrastructure. - Don't require zeroing of non-shared SVE state during syscalls. v6: - Rebase onto v5.16-rc1. - Return to disabling TIF_SVE on kernel entry even if we have SME state, this avoids the need for KVM to handle the case where TIF_SVE is set on guest entry. - Add syscall-abi.h to SME updates to syscall-abi, mistakenly omitted from commit. v5: - Rebase onto currently merged SVE and kselftest patches. - Add support for the FA64 option, introduced in the recently published EAC1 update to the specification. - Pull in test program for the syscall ABI previously sent separately with some revisions and add coverage for the SME ABI. - Fix checking for options with 1 bit fields in ID_AA64SMFR0_EL1. - Minor fixes and clarifications to the ABI documentation. v4: - Rebase onto merged patches. - Remove an uneeded NULL check in vec_proc_do_default_vl(). - Include patch to factor out utility routines in kselftests written in assembler. - Specify -ffreestanding when building TPIDR2 test. v3: - Skip FFR rather than predicate registers in sve_flush_live(). - Don't assume a bool is all zeros in sve_flush_live() as per AAPCS. - Don't redundantly specify a zero index when clearing FFR. v2: - Fix several issues with !SME and !SVE configurations. - Preserve TPIDR2 when creating a new thread/process unless CLONE_SETTLS is set. - Report traps due to using features in an invalid mode as SIGILL. - Spell out streaming mode behaviour in SVE ABI documentation more directly. - Document TPIDR2 in the ABI document. - Use SMSTART and SMSTOP rather than read/modify/write sequences. - Rework logic for exiting streaming mode on syscall. - Don't needlessly initialise SVCR on access trap. - Always restore SME VL for userspace if SME traps are disabled. - Only yield to encourage preemption every 128 iterations in za-test, otherwise do a getpid(), and validate SVCR after syscall. - Leave streaming mode disabled except when reading the vector length in za-test, and disable ZA after detecting a mismatch. - Add SME support to vlset. - Clarifications and typo fixes in comments. - Move sme_alloc() forward declaration back a patch.

[PATCH] kunit: tool: make parser preserve whitespace when printing test log

by Daniel Latypov

Currently, kunit_parser.py is stripping all leading whitespace to make parsing easier. But this means we can't accurately show kernel output for failing tests or when the kernel crashes. Embarassingly, this affects even KUnit's own output, e.g. [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] not ok 1 example_simple_test [13:40:46] [FAILED] example_simple_test After this change, here's what the output in context would look like [13:40:46] =================== example (4 subtests) =================== [13:40:46] # example_simple_test: initializing [13:40:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29 [13:40:46] Expected 2 + 1 == 2, but [13:40:46] 2 + 1 == 3 (0x3) [13:40:46] [FAILED] example_simple_test [13:40:46] [SKIPPED] example_skip_test [13:40:46] [SKIPPED] example_mark_skipped_test [13:40:46] [PASSED] example_all_expect_macros_test [13:40:46] # example: initializing suite [13:40:46] # example: pass:1 fail:1 skip:2 total:4 [13:40:46] # Totals: pass:1 fail:1 skip:2 total:4 [13:40:46] ===================== [FAILED] example ===================== This example shows one minor cosmetic defect this approach has. The test counts lines prevent us from dedenting the suite-level output. But at the same time, any form of non-KUnit output would do the same unless it happened to be indented as well.

[PATCH RESEND] Documentation: dev-tools: Clarify requirements for result description

by Mark Brown

Currently the KTAP specification says that a test result line is <result> <number> [<description>][ # [<directive>] [<diagnostic data>]] and the description of a test can be "any sequence of words (can't include #)" which specifies that there may be more than one word but does not specify anything other than those words which might be used to separate the words which probably isn't what we want. Given that practically we have tests using a range of separators for words including combinations of spaces and combinations of other symbols like underscores or punctuation let's just clarify that the description can contain any character other than # (marking the start of the directive/diagnostic) or newline (marking the end of this test result).

[PATCH v2] Documentation: kunit: Fix "How Do I Use This" / "Next Steps" sections

by David Gow

The "How Do I Use This" section of index.rst and "Next Steps" section of start.rst were just copies of the table of contents, and therefore weren't really useful either when looking a sphinx generated output (which already had the TOC visible) or when reading the source (where it's just a list of files that ls could give you). Instead, provide a small number of concrete next steps, and a bit more description about what the pages contain. This also removes the broken reference to 'tips.rst', which was previously removed.

[PATCH v3 0/2] kunit: add macro to allow conditionally exposing static symbols to tests

by Rae Moar

Currently in order to test a static function, tests must be included in the same translation unit as the function. However, this can cause issues with including implementation and test code in the same file. As an alternative, the first patch in this series creates a macro that will set a function to be static or not depending on whether CONFIG_KUNIT is enabled. This allows the function to be visible during testing and static otherwise. As an example, the current status quo to test static functions is: === test.c === static void test_case(struct kunit *test) { KUNIT_EXPECT_EQ(test, my_func_to_test(), 2); } Then the tests are included in the implementation file as a workaround to the issue of testing static functions: === implementation.c === static int my_func_to_test() {...} ... #include "test.c" Instead, the function could be defined with this new macro: === implementation.c === VISIBLE_IF_KUNIT int my_func_to_test() {...} The first patch also creates a macro that will export a symbol into a kunit testing namespace only if CONFIG_KUNIT is enabled. This follows the logic above and allows symbols to be conditionally exported based on the testing status. The second patch in the series updates the policy_unpack test in AppArmor to show an example of how to use both of these macros in order to address the issue of testing static functions. Additionally, the patch allows the policy_unpack test to be built as a module.

[PATCH v5 0/6] mm/memfd: introduce MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control behavior of X bit. For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V4 version of patch: see [4] [5] [6] for previous versions.

[PATCH v5 00/19] IOMMUFD Generic interface

by Jason Gunthorpe

[ This update is primarily collecting remarks from the mailing list, lots of doc fixes and it is now stably in linux-next without warnings/etc. syzbot has taken over and is running now, the remaining static tool feedback has been collected. s390, Intel x86, ARM and all the VFIO mdevs have been tested now. ] iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory. It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things. As these features are fundamental to a VM platform they need to be uniformly exposed to all the driver families that do DMA into VMs, which is currently VFIO and VDPA. The pre-v1 series proposed re-using the VFIO type 1 data structure, however it was suggested that if we are doing this big update then we should also come with an improved data structure that solves the limitations that VFIO type1 has. Notably this addresses: - Multiple IOAS/'containers' and multiple domains inside a single FD - Single-pin operation no matter how many domains and containers use a page - A fine grained locking scheme supporting user managed concurrency for multi-threaded map/unmap - A pre-registration mechanism to optimize vIOMMU use cases by pre-pinning pages - Extended ioctl API that can manage these new objects and exposes domains directly to user space - domains are sharable between subsystems, eg VFIO and VDPA The bulk of this code is a new data structure design to track how the IOVAs are mapped to PFNs. iommufd intends to be general and consumable by any driver that wants to DMA to userspace. From a driver perspective it can largely be dropped in in-place of iommu_attach_device() and provides a uniform full feature set to all consumers. As this is a larger project this series is the first step. This series provides the iommfd "generic interface" which is designed to be suitable for applications like DPDK and VMM flows that are not optimized to specific HW scenarios. It is close to being a drop in replacement for the existing VFIO type 1 and supports existing qemu based VM flows. Several follow-on series are being prepared: - Patches integrating with qemu in native mode: https://github.com/yiliu1765/qemu/commits/qemu-iommufd-6.0-rc2 - A completed integration with VFIO now exists that covers "emulated" mdev use cases now, and can pass testing with qemu/etc in compatability mode: https://github.com/jgunthorpe/linux/commits/vfio_iommufd - A draft providing system iommu dirty tracking on top of iommufd, including iommu driver implementations: https://github.com/jpemartins/linux/commits/x86-iommufd This pairs with patches for providing a similar API to support VFIO-device tracking to give a complete vfio solution: https://lore.kernel.org/kvm/20220901093853.60194-1-yishaih@nvidia.com/ - Userspace page tables aka 'nested translation' for ARM and Intel iommu drivers: https://github.com/nicolinc/iommufd/commits/iommufd_nesting - "device centric" vfio series to expose the vfio_device FD directly as a normal cdev, and provide an extended API allowing dynamically changing the IOAS binding: https://github.com/yiliu1765/iommufd/commits/iommufd-v6.0-rc2-nesting-0901 - Drafts for PASID and PRI interfaces are included above as well Overall enough work is done now to show the merit of the new API design and at least draft solutions to many of the main problems. Several people have contributed directly to this work: Eric Auger, Joao Martins, Kevin Tian, Lu Baolu, Nicolin Chen, Yi L Liu. Many more have participated in the discussions that lead here, and provided ideas. Thanks to all! The v1/v2 iommufd series has been used to guide a large amount of preparatory work that has now been merged. The general theme is to organize things in a way that makes injecting iommufd natural: - VFIO live migration support with mlx5 and hisi_acc drivers.

[PATCH v4 3/6] mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> The new MFD_NOEXEC_SEAL and MFD_EXEC flags allows application to set executable bit at creation time (memfd_create). When MFD_NOEXEC_SEAL is set, memfd is created without executable bit (mode:0666), and sealed with F_SEAL_EXEC, so it can't be chmod to be executable (mode: 0777) after creation. when MFD_EXEC flag is set, memfd is created with executable bit (mode:0777), this is the same as the old behavior of memfd_create.

[PATCH v4 3/6] mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> The new MFD_NOEXEC_SEAL and MFD_EXEC flags allows application to set executable bit at creation time (memfd_create). When MFD_NOEXEC_SEAL is set, memfd is created without executable bit (mode:0666), and sealed with F_SEAL_EXEC, so it can't be chmod to be executable (mode: 0777) after creation. when MFD_EXEC flag is set, memfd is created with executable bit (mode:0777), this is the same as the old behavior of memfd_create. The new pid namespaced sysctl vm.memfd_noexec has 3 values: 0: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like MFD_EXEC was set. 1: memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL acts like MFD_NOEXEC_SEAL was set. 2: memfd_create() without MFD_NOEXEC_SEAL will be rejected. The sysctl allows finer control of memfd_create for old-software that doesn't set the executable bit, for example, a container with vm.memfd_noexec=1 means the old-software will create non-executable memfd by default.

[PATCH v4 0/6] mm/memfd: add MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control behavior of X bit. For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V4 version of patch: see [4] [5] [6] for previous versions.

[PATCH v2 0/2] kunit: add macro to allow conditionally exposing static symbols to tests

by Rae Moar

Currently in order to test a static function, tests must be included in the same translation unit as the function. However, this can cause issues with including implementation and test code in the same file. As an alternative, the first patch in this series creates a macro that will set a function to be static or not depending on whether CONFIG_KUNIT is enabled. This allows the function to be visible during testing and static otherwise. As an example, the current status quo to test static functions is: === test.c === static void test_case(struct kunit *test) { KUNIT_EXPECT_EQ(test, my_func_to_test(), 2); } Then the tests are included in the implementation file as a workaround to the issue of testing static functions: === implementation.c === static int my_func_to_test() {...} ... #include "test.c" Instead, the function could be defined with this new macro: === implementation.c === VISIBLE_IF_KUNIT int my_func_to_test() {...} The first patch also creates a macro that will export a symbol into a kunit testing namespace only if CONFIG_KUNIT is enabled. This follows the logic above and allows symbols to be conditionally exported based on the testing status. The second patch in the series updates the policy_unpack test in AppArmor to show an example of how to use both of these macros in order to address the issue of testing static functions. Thanks! -Rae Changes since v1: - Changed the namespace of exported symbols for the apparmor policy_unpack_test by adding the aa_ prefix. - Separated the documentation comments for macros in include/kunit/visibility.h. - Changed copyright date and author for include/kunit/visibility.h.

[PATCH bpf-next,v6 0/4] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c. --- changes in v6: fix sparse warning in patch 2 changes in v5: - avoid cleanup of percpu dsts as detailed in patch 2 changes in v3: - tag bpf-next tree instead of ipsec-next - add IFLA_XFRM_COLLECT_METADATA sync patch Eyal Birger (4): xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c xfrm: interface: Add unstable helpers for setting/getting XFRM metadata from TC-BPF tools: add IFLA_XFRM_COLLECT_METADATA to uapi/linux/if_link.h selftests/bpf: add xfrm_info tests include/net/dst_metadata.h | 1 + include/net/xfrm.h | 17 + net/core/dst.c | 8 +- net/core/filter.c | 9 + net/xfrm/Makefile | 8 + net/xfrm/xfrm_interface_bpf.c | 115 ++++++ ...xfrm_interface.c => xfrm_interface_core.c} | 14 + tools/include/uapi/linux/if_link.h | 1 + tools/testing/selftests/bpf/DENYLIST.s390x | 1 + tools/testing/selftests/bpf/config | 2 + .../selftests/bpf/prog_tests/xfrm_info.c | 365 ++++++++++++++++++ .../selftests/bpf/progs/bpf_tracing_net.h | 3 + tools/testing/selftests/bpf/progs/xfrm_info.c | 35 ++ 13 files changed, 577 insertions(+), 2 deletions(-) create mode 100644 net/xfrm/xfrm_interface_bpf.c rename net/xfrm/{xfrm_interface.c => xfrm_interface_core.c} (98%) create mode 100644 tools/testing/selftests/bpf/prog_tests/xfrm_info.c create mode 100644 tools/testing/selftests/bpf/progs/xfrm_info.c -- 2.34.1

[PATCH mm-unstable v1 0/4] selftests/vm: fix some tests on 32bit

by David Hildenbrand

I finally had the time to run some of the selftests written by me (especially "cow") on x86 PAE. I found some unexpected "surprises" :) With these changes, and with [1] on top of mm-unstable, the "cow" tests and the "ksm_functional_tests" compile and pass as expected (expected failures with hugetlb in the "cow" tests). "madv_populate" has one expected test failure -- x86 does not support softdirty tracking. #1-#3 fix commits with stable commit ids. #4 fixes a test that is not in mm-stable yet. A note that there are many other compile errors/warnings when compiling on 32bit and with older Linux headers ... something for another day.

[PATCH v2 0/2] livepatch: Move tests from lib/livepatch to selftests/livepatch

by Marcos Paulo de Souza

Hi there, this is the v2 of the patchset. The v1 can be found at [1]. There is only one change in patch 1, which changed the target directory to build the test modules. All other changes happen in patch 2. Thanks for reviewing! Changes from v1: # test_modules/Makefile * Build the test modules targeting /lib/modules, instead of ksrc when building from the kernel source. # test_modules/test_klp_syscall.c * Added a parameter array to receive the pids that should transition to the new system call. (suggedted by Joe) * Create a new sysfs file /sys/kernel/test_klp_syscall/npids to show how many pids from the argument need to transition to the new state. (suggested by Joe) * Fix the PPC32 support by adding the syscall wrapper for archs that select it by default, without erroring out. PPC does not set SYSCALL_WRAPPER, so having it set in v1 was a mistake. (suggested by Joe) * The aarch64 syscall prefix was added too, since the livepatch support will come soon. # test_binaries/test_klp-call_getpid.c * Change %d/%u in printf (suggested byu Joe) * Change run -> stop variable name, and inverted the assignments (suggested by * Joe). # File test-syscall.sh * Fixed test-syscall.sh to call test_klp-call-getpid in test_binaries dir * Load test_klp_syscall passed the pids of the test_klp-call_getpid instances. Check the sysfs file from test_klp_syscall module to check that all pids transitioned correctly. (suggested by Joe) * Simplified the loop that calls test_klp-call_getpid. (suggested by Joe) * Removed the "success" comment from the script, as it's implicit that it succeed. Otherwise load_lp would error out. (suggested by Joe) * Changed the commit message of patch 2 to further detail what means "tricky" when livepatching syscalls.

[PATCH v4 1/3] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs. Signed-off-by: David Gow <davidgow(a)google.com> Reviewed-by: Daniel Latypov <dlatypov(a)google.com> --- This should be a no-op (other than a possible performance improvement) functionality-wise, and lays the groundwork for a more optimised static stub implementation. The remaining patches in the series add a kunit_get_current_test() function which is a more friendly and performant wrapper around current->kunit_test, and use this in the slub test. They also improve the documentation a bit. If there are no objections, we'll take the whole series via the KUnit tree.

[PATCH bpf-next,v4 0/4] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c. --- Series changes in v3: - tag bpf-next tree instead of ipsec-next - add IFLA_XFRM_COLLECT_METADATA sync patch Eyal Birger (4): xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c xfrm: interface: Add unstable helpers for setting/getting XFRM metadata from TC-BPF tools: add IFLA_XFRM_COLLECT_METADATA to uapi/linux/if_link.h selftests/bpf: add xfrm_info tests include/net/dst_metadata.h | 1 + include/net/xfrm.h | 20 + net/core/dst.c | 8 +- net/xfrm/Makefile | 8 + net/xfrm/xfrm_interface_bpf.c | 123 ++++++ ...xfrm_interface.c => xfrm_interface_core.c} | 15 + tools/include/uapi/linux/if_link.h | 1 + tools/testing/selftests/bpf/DENYLIST.s390x | 1 + tools/testing/selftests/bpf/config | 2 + .../selftests/bpf/prog_tests/xfrm_info.c | 365 ++++++++++++++++++ .../selftests/bpf/progs/bpf_tracing_net.h | 3 + tools/testing/selftests/bpf/progs/xfrm_info.c | 35 ++ 12 files changed, 580 insertions(+), 2 deletions(-) create mode 100644 net/xfrm/xfrm_interface_bpf.c rename net/xfrm/{xfrm_interface.c => xfrm_interface_core.c} (98%) create mode 100644 tools/testing/selftests/bpf/prog_tests/xfrm_info.c create mode 100644 tools/testing/selftests/bpf/progs/xfrm_info.c -- 2.34.1

[PATCH v3] mm/memfd: MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control behavior of X bit. For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V3 version of patch: see [4] [5] for previous versions.

[PATCH] selftests/ftrace: Use long for synthetic event probe test

by Steven Rostedt

From 8bb1734388b89bdb2ac176882786dc02b7df92c2 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> Date: Wed, 30 Nov 2022 17:31:34 -0500 Subject: [PATCH] selftests/ftrace: Use long for synthetic event probe test On 32bit the trigger-synthetic-eprobe.tc selftest fails with the error: hist:syscalls:sys_exit_openat: error: Param type doesn't match synthetic event field type Command: hist:keys=common_pid:filename=$__arg__1,ret=ret:onmatch(syscalls.sys_enter_openat).trace(synth_open,$filename,$ret) ^ This is because the synth_open synthetic event is created with: echo "$SYNTH u64 filename; s64 ret;" > synthetic_events Which works fine on 64 bit, as filename is a pointer and the return is also a long. But for 32 bit architectures, it doesn't work. Use "unsigned long" and "long" instead so that it works for both 64 bit and 32 bit architectures.

[PATCH v1 0/6] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards.

[PATCH v2 0/3] kselftest/arm64: fp-stress performance improvements

by Mark Brown

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal. v2: - Rebase onto arm64/for-next/selftests Mark Brown (3): kselftest/arm64: Hold fp-stress children until they're all spawned kselftest/arm64: Don't drain output while spawning children kselftest/arm64: Allow epoll_wait() to return more than one result tools/testing/selftests/arm64/fp/fp-stress.c | 74 +++++++++++++++----- 1 file changed, 57 insertions(+), 17 deletions(-) base-commit: 642978981ec8a79da00828c696c58b3732b993a6 -- 2.30.2

[PATCH net-next 00/11] mptcp: PM listener events + selftests cleanup

by Matthieu Baerts

Thanks to the patch 6/11, the MPTCP path manager now sends Netlink events when MPTCP listening sockets are created and closed. The reason why it is needed is explained in the linked ticket [1]: MPTCP for Linux, when not using the in-kernel PM, depends on the userspace PM to create extra listening sockets before announcing addresses and ports. Let's call these "PM listeners". With the existing MPTCP netlink events, a userspace PM can create PM listeners at startup time, or in response to an incoming connection. Creating sockets in response to connections is not optimal: ADD_ADDRs can't be sent until the sockets are created and listen()ed, and if all connections are closed then it may not be clear to the userspace PM daemon that PM listener sockets should be cleaned up. Hence this feature request: to add MPTCP netlink events for listening socket close & create, so PM listening sockets can be managed based on application activity. [1] https://github.com/multipath-tcp/mptcp_net-next/issues/313 Selftests for these new Netlink events have been added in patches 9,11/11. The remaining patches introduce different cleanups and small improvements in MPTCP selftests to ease the maintenance and the addition of new tests.

[PATCH v3 0/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

by Janis Schoetterl-Glausch

User space can use the MEM_OP ioctl to make storage key checked reads and writes to the guest, however, it has no way of performing atomic, key checked, accesses to the guest. Extend the MEM_OP ioctl in order to allow for this, by adding a cmpxchg mode. For now, support this mode for absolute accesses only. This mode can be use, for example, to set the device-state-change indicator and the adapter-local-summary indicator atomically. Also contains some fixes/changes for the memop selftest independent of the cmpxchg changes. v2 -> v3 * rebase onto the wip/cmpxchg_user_key branch in the s390 kernel repo * use __uint128_t instead of unsigned __int128 * put moving of testlist into main into separate patch * pick up R-b's (thanks Nico) v1 -> v2 * get rid of xrk instruction for cmpxchg byte and short implementation * pass old parameter via pointer instead of in mem_op struct * indicate failure of cmpxchg due to wrong old value by special return code * picked up R-b's (thanks Thomas) Janis Schoetterl-Glausch (9): KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg Documentation: KVM: s390: Describe KVM_S390_MEMOP_F_CMPXCHG KVM: s390: selftest: memop: Pass mop_desc via pointer KVM: s390: selftest: memop: Replace macros by functions KVM: s390: selftest: memop: Move testlist into main KVM: s390: selftest: memop: Add cmpxchg tests KVM: s390: selftest: memop: Add bad address test KVM: s390: selftest: memop: Fix typo KVM: s390: selftest: memop: Fix wrong address being used in test Documentation/virt/kvm/api.rst | 21 +- include/uapi/linux/kvm.h | 5 + arch/s390/kvm/gaccess.h | 3 + arch/s390/kvm/gaccess.c | 101 ++++ arch/s390/kvm/kvm-s390.c | 35 +- tools/testing/selftests/kvm/s390x/memop.c | 670 +++++++++++++++++----- 6 files changed, 683 insertions(+), 152 deletions(-) Range-diff against v2: 1: c6731b0063ab ! 1: 94820a73e9b0 KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg @@ arch/s390/kvm/gaccess.h: int access_guest_with_key(struct kvm_vcpu *vcpu, unsign void *data, unsigned long len, enum gacc_mode mode);

[PATCH v3 0/7] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration, support for providing user visible descriptions and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v3: - "Rebase" onto Takashi's current tree (with a revert). - Include Jaroslav's changes to specify all tests in the configuration file parsing. - Add a new "description" field to the configuration instead of trying to name the tests. - Always run both default and per-system tests, logging our success at setting the per-system configurations as a separate test since they shouldn't fail. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing.

[PATCH] kselftests/alsa: pcm - move more configuration to configuration files

by Jaroslav Kysela

Obtain all test parameters from the configuration files. The defaults are defined in the pcm-test.conf file. The test count and parameters may be variable per specific hardware. Also, handle alt_formats field now (with the fixes in the format loop). It replaces the original "automatic" logic which is not so universal. The code may be further extended to skip various tests based on the configuration hints, if the exact PCM hardware parameters are not available for the given hardware.

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing. Mark Brown (6): kselftest/alsa: Refactor pcm-test to list the tests to run in a struct kselftest/alsa: Report failures to set the requested sample rate as skips kselftest/alsa: Report failures to set the requested channels as skips kselftest/alsa: Don't any configuration in the sample config kselftest/alsa: Provide more meaningful names for tests kselftest/alsa: Add more coverage of sample rates and channel counts .../alsa/conf.d/Lenovo_ThinkPad_P1_Gen2.conf | 35 ++++---- tools/testing/selftests/alsa/pcm-test.c | 88 +++++++++++++------ 2 files changed, 81 insertions(+), 42 deletions(-) base-commit: 2133dc91d6658242009177b564ac47c49e08668a -- 2.30.2

[PATCH] selftests/damon: test removed scheme sysfs dir access bug

by SeongJae Park

A DAMON sysfs user could start DAMON with a scheme, remove the sysfs directory for the scheme, and then ask stats or schemes tried regions update. The related logic were not aware of the already removed directory situation, so it was able to results in invalid memory accesses. The fix has made with commit 8468b486612c ("mm/damon/sysfs-schemes: skip stats update if the scheme directory is removed"), though. Add a selftest to avoid such kind of bugs be introduced again.

For example you could define an enum vc4_pixelvalve type and have something like the following: const struct vc4_pv_data *vc4_crtc_get_pixelvalve_data(enum vc4_pixelvalve pv); All these are small nits though, the patch looks great to me and I think is awesome to have this level of testing with KUnit.

So that including it in drivers will be a no-op. Or do you plan to conditionally include this header file in drivers? So that is only included when CONFIG_DRM_KUNIT_TEST is enabled? Another thing that wondered is if we want a different namespace for this header, i.e: <drm/testing/drm_kunit_helpers.h>, to make it clear that is not part of the DRM API but just for testing helpers.

[PATCH ipsec-next 0/3] xfrm: interface: Add unstable helpers for XFRM metadata

by Eyal Birger

This patch series adds xfrm metadata helpers using the unstable kfunc call interface for the TC-BPF hooks. This allows steering traffic towards different IPsec connections based on logic implemented in bpf programs. The helpers are integrated into the xfrm_interface module. For this purpose the main functionality of this module is moved to xfrm_interface_core.c. Eyal Birger (3): xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c xfrm: interface: Add unstable helpers for setting/getting XFRM metadata from TC-BPF selftests/bpf: add xfrm_info tests include/net/dst_metadata.h | 1 + include/net/xfrm.h | 20 + net/core/dst.c | 4 + net/xfrm/Makefile | 8 + net/xfrm/xfrm_interface_bpf.c | 92 +++++ ...xfrm_interface.c => xfrm_interface_core.c} | 15 + tools/testing/selftests/bpf/config | 2 + .../selftests/bpf/prog_tests/test_xfrm_info.c | 342 ++++++++++++++++++ .../selftests/bpf/progs/test_xfrm_info_kern.c | 74 ++++ 9 files changed, 558 insertions(+) create mode 100644 net/xfrm/xfrm_interface_bpf.c rename net/xfrm/{xfrm_interface.c => xfrm_interface_core.c} (98%) create mode 100644 tools/testing/selftests/bpf/prog_tests/test_xfrm_info.c create mode 100644 tools/testing/selftests/bpf/progs/test_xfrm_info_kern.c -- 2.34.1

[RFC PATCH v2 00/11] implement DAMOS filtering for anon pages and

by SeongJae Park

Changes from RFC v1 (https://lore.kernel.org/damon/20221124212114.136863-1-sj@kernel.org/) - sysfs: Clean up filters directory from scheme directory cleanup path - sysfs: Link newly created filter to the scheme - sysfs: Ignore removed memcg when checking path - sysfs: Guard 'struct mem_cgroup' access with CONFIG_MEMCG (kernel test robot) ---- DAMOS let users do system operations in a data access pattern oriented way. The data access pattern, which is extracted by DAMON, is somewhat accurate more than what user space could know in many cases. However, in some situation, users could know something more than the kernel about the pattern or some special requirements for some types of memory or processes. For example, some users would have slow swap devices and knows latency-ciritical processes and therefore want to use DAMON-based proactive reclamation (DAMON_RECLAIM) for only non-anonymous pages of non-latency-critical processes. For such restriction, users could exclude the memory regions from the initial monitoring regions and use non-dynamic monitoring regions update monitoring operations set including fvaddr and paddr. They could also adjust the DAMOS target access pattern. For dynamically changing memory layout and access pattern, those would be not enough. To help the case, add an interface, namely DAMOS filters, which can be used to avoid the DAMOS actions be applied to specific types of memory, to DAMON kernel API (damon.h). At the moment, it supports filtering anonymous pages and/or specific memory cgroups in or out for each DAMOS scheme. This patchset adds the support for all DAMOS actions that 'paddr' monitoring operations set supports ('pageout', 'lru_prio', and 'lru_deprio'), and the functionality is exposed via DAMON kernel API (damon.h) the DAMON sysfs interface (/sys/kernel/mm/damon/admins/), and DAMON_RECLAIM module parameters. Patches Sequence ---------------- First patch implements DAMOS filter interface to DAMON kernel API. Second patch makes the physical address space monitoring operations set to support the filters from all supporting DAMOS actions. Third patch adds anonymous pages filter support to DAMON_RECLAIM, and the fourth patch documents the DAMON_RECLAIM's new feature. Fifth to seventh patches implement DAMON sysfs files for support of the filters, and eighth patch connects the file to use DAMOS filters feature. Ninth patch adds simple self test cases for DAMOS filters of the sysfs interface. Finally, following two patches (tenth and eleventh) document the new features and interfaces.

That is, just define the simpler macros when is disabled? The kunit_fail_current_test() is just a no-op if CONFIG_KUNIT isn't enabled, but I think my question still stands.

[PATCH net-next 0/8] mptcp: MSG_FASTOPEN and TFO listener side support

by Matthieu Baerts

Before this series, only the initiator of a connection was able to combine both TCP FastOpen and MPTCP when using TCP_FASTOPEN_CONNECT socket option. These new patches here add (in theory) the full support of TFO with MPTCP, which means: - MSG_FASTOPEN sendmsg flag support (patch 1/8) - TFO support for the listener side (patches 2-5/8) - TCP_FASTOPEN socket option (patch 6/8) - TCP_FASTOPEN_KEY socket option (patch 7/8) To support TFO for the server side, a few preparation patches are needed (patches 2 to 5/8). Some of them were inspired by a previous work from Benjamin Hesmans. Note that TFO support with MPTCP has been validated with selftests (patch 8/8) but also with Packetdrill tests running with a modified but still very WIP version supporting MPTCP. Both the modified tool and the tests are available online: https://github.com/multipath-tcp/packetdrill/ Dmytro Shytyi (5): mptcp: add MSG_FASTOPEN sendmsg flag support mptcp: implement delayed seq generation for passive fastopen mptcp: add subflow_v(4,6)_send_synack() mptcp: add TCP_FASTOPEN sock option selftests: mptcp: mptfo Initiator/Listener Matthieu Baerts (1): mptcp: add support for TCP_FASTOPEN_KEY sockopt Paolo Abeni (2): mptcp: track accurately the incoming MPC suboption type mptcp: consolidate initial ack seq generation net/mptcp/Makefile | 2 +- net/mptcp/fastopen.c | 73 ++++++++ net/mptcp/options.c | 25 ++- net/mptcp/protocol.c | 39 +--- net/mptcp/protocol.h | 28 ++- net/mptcp/sockopt.c | 9 +- net/mptcp/subflow.c | 105 ++++++++--- .../selftests/net/mptcp/mptcp_connect.c | 171 +++++++++++++----- .../selftests/net/mptcp/mptcp_connect.sh | 21 +++ 9 files changed, 358 insertions(+), 115 deletions(-) create mode 100644 net/mptcp/fastopen.c Cc: Benjamin Hesmans <benjamin.hesmans(a)tessares.net> base-commit: a6e3d86ece0b42a571a11055ace5c3148cb7ce76 -- 2.37.2

We print the "test log" on failure. This is meant to be all the kernel output that happened during the test. But we also include the special KTAP lines in it, which are often redundant.

[PATCH v1 0/3] kselftest/arm64: fp-stress performance improvements

by Mark Brown

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal.

[PATCH v5 net-next 8/8] selftests: Add a basic HSR test.

by Sebastian Andrzej Siewior

This test adds a basic HSRv0 network with 3 nodes. In its current shape it sends and forwards packets, announcements and so merges nodes based on MAC A/B information. It is able to detect duplicate packets and packetloss should any occur.

[RFC net-next 0/6] Allow excluding sw flow key from upcalls

by Aaron Conole

Userspace applications can choose to completely ignore the kernel provided flow key and instead regenerate a fresh key for processing in userspace. Currently, userspace ovs-vswitchd does this in some instances (for example, MISS upcall command). This means that kernel spends time to copy and send the flow key into userspace without any benefit to the system. Introduce a way for userspace to tell kernel not to send the flow key. This lets userspace and kernel space save time and memory pressure. This patch set is quite a bit larger because it introduces the ability to decode a sw flow key into a compatible datapath-string. We use this as a method of implementing a test to show that the feature is working by decoding and dumping the flow (to make sure we capture the correct packet).

[PATCH] selftests: alsa - move shared library configuration code to conf.c

by Jaroslav Kysela

The minimal alsa-lib configuration code is similar in both mixer and pcm tests. Move this code to the shared conf.c source file. Also, fix the build rules inspired by rseq tests. Build libatest.so which is linked to the both test utilities dynamically. Also, set the TEST_FILES variable for lib.mk.

[PATCH mm-unstable v1 00/20] mm/gup: remove FOLL_FORCE usage from drivers (reliable R/O long-term pinning)

by David Hildenbrand

For now, we did not support reliable R/O long-term pinning in COW mappings. That means, if we would trigger R/O long-term pinning in MAP_PRIVATE mapping, we could end up pinning the (R/O-mapped) shared zeropage or a pagecache page. The next write access would trigger a write fault and replace the pinned page by an exclusive anonymous page in the process page table; whatever the process would write to that private page copy would not be visible by the owner of the previous page pin: for example, RDMA could read stale data. The end result is essentially an unexpected and hard-to-debug memory corruption. Some drivers tried working around that limitation by using "FOLL_FORCE|FOLL_WRITE|FOLL_LONGTERM" for R/O long-term pinning for now. FOLL_WRITE would trigger a write fault, if required, and break COW before pinning the page. FOLL_FORCE is required because the VMA might lack write permissions, and drivers wanted to make that working as well, just like one would expect (no write access, but still triggering a write access to break COW). However, that is not a practical solution, because (1) Drivers that don't stick to that undocumented and debatable pattern would still run into that issue. For example, VFIO only uses FOLL_LONGTERM for R/O long-term pinning. (2) Using FOLL_WRITE just to work around a COW mapping + page pinning limitation is unintuitive. FOLL_WRITE would, for example, mark the page softdirty or trigger uffd-wp, even though, there actually isn't going to be any write access. (3) The purpose of FOLL_FORCE is debug access, not access without lack of VMA permissions by arbitrarty drivers. So instead, make R/O long-term pinning work as expected, by breaking COW in a COW mapping early, such that we can remove any FOLL_FORCE usage from drivers and make FOLL_FORCE ptrace-specific (renaming it to FOLL_PTRACE). More details in patch #8. Patches #1--#3 add COW tests for non-anonymous pages. Patches #4--#7 prepare core MM for extended FAULT_FLAG_UNSHARE support in COW mappings. Patch #8 implements reliable R/O long-term pinning in COW mappings Patches #9--#19 remove any FOLL_FORCE usage from drivers. Patch #20 renames FOLL_FORCE to FOLL_PTRACE. I'm refraining from CCing all driver/arch maintainers on the whole patch set, but only CC them on the cover letter and the applicable patch (I know, I know, someone is always unhappy ... sorry).

[PATCH bpf-next v1 0/4] Add BPF htab map's used size for monitoring

by Ho-Ren (Jack) Chuang

Hello everyone, We have prepared patches to address an issue from a previous discussion. The previous discussion email thread is here: https://lore.kernel.org/all/CAADnVQLBt0snxv4bKwg1WKQ9wDFbaDCtZ03v1-LjOTYtsK… This patch series adds a new field "used_entries" to struct bpf_map_info and keeps tracking the "count" field in bpf_htab in both the preallocated and non-preallocated cases. bpftool is modified to report the newly added "used_entries" field in struct bpf_map_info and to mark pre-allocated htab maps with "*". These make it easier to view the current memory situation of a hashmap. We have added a new interface function map_get_used_elem in bpf_map_ops to provide an abstraction layer so that other map type implementations can support the "used_entries" attribute in a future change. A concurrency testing for pre-allocated and dynamically allocated htab maps is introduced to test the correctness and performance of htab map's used size. Existing unit tests are integrated to test the correctness of htab map's used size. Thank you, Ho-Ren (Jack) Chuang (4): bpf: Support reporting BPF htab map's used size for monitoring bpftool: Add tools support to show BPF htab map's used size samples/bpf: Add concurrency testing for BPF htab map's used size selftests/bpf: Add unit tests for BPF htab map's used size include/linux/bpf.h | 1 + include/uapi/linux/bpf.h | 1 + kernel/bpf/hashtab.c | 19 +++ kernel/bpf/syscall.c | 2 + samples/bpf/Makefile | 4 + samples/bpf/test_map_used_kern.c | 65 ++++++++ samples/bpf/test_map_used_user.c | 204 ++++++++++++++++++++++++ tools/bpf/bpftool/map.c | 9 +- tools/include/uapi/linux/bpf.h | 1 + tools/testing/selftests/bpf/test_maps.c | 74 ++++++++- 10 files changed, 377 insertions(+), 3 deletions(-) create mode 100644 samples/bpf/test_map_used_kern.c create mode 100644 samples/bpf/test_map_used_user.c -- Ho-Ren (Jack) Chuang

Other than the comments that I pointed out in the series, I believe that a small entry on the VC4 documentation would be nice to cover how to run the tests and also what the tests are currently covering.

Maybe it would be better to separate the compilation of the drm_kunit_helpers from the compilation of the rest of the DRM tests. This way, this Kconfig entry could be dropped and only the vc4 tests would run. Moreover, it would allow to run the vc4 tests with --arch=arm.

[PATCH v8 00/26] tcp: Initial support for RFC5925 auth option

by Leonard Crestez

This is similar to TCP-MD5 in functionality but it's sufficiently different that packet formats and interfaces are incompatible. Compared to TCP-MD5 more algorithms are supported and multiple keys can be used on the same connection but there is still no negotiation mechanism. Expected use-case is protecting long-duration BGP/LDP connections between routers using pre-shared keys. The goal of this series is to allow routers using the Linux TCP stack to interoperate with vendors such as Cisco and Juniper. An fully-featured userspace implementation using this patchset exists but it is not open. A completely unrelated series that implements the same features was posted recently: https://lore.kernel.org/netdev/20220818170005.747015-1-dima@arista.com/ The biggest difference is that this series puts TCP-AO key on a global instead of per-socket list and that it attempts to make kernel-mode key selection decisions instead of very strictly requiring userspace to make all decisions. I believe my approach greatly simplifies userspace implementation. The biggest difference in this iteration of the patch series is adding per-key lifetime values based on RFC8177 in order to implement kernel-mode key rollover. Older versions still required userspace to tweak the NOSEND/NORECV flags and always pick rnextkeyid explicitly, but now no active "key management" should be required on established socket - Just set correct flags and expiration dates and the kernel can perform key rollover itself. You can see a (simple) test of that behavior here: https://github.com/cdleonard/tcp-authopt-test/blob/main/tcp_authopt_test/te… The main implementation of this behavior is patch 17. Very very old versions of this series had per-socket keys but that approach was prone to an issue when key change made on a listen socket between "synack" and "accept" did not affect the new socket. My solution was to make keys global, the Arista solution is to require userspace to query the key list on accepted sockets and update them. This offloads responsibility for an ABI race to userspace. It can be made to work. Here are some known flaws and limitations: * Crypto API is used with buffers on the stack and inside struct sock, this might not work on all arches. I'm currently only testing x64 VMs * Interaction with FASTOPEN not tested. * Traffic key is not cached (reducing performance). * All lookups examine all keys, ignoring optimization opportunities * Overlaping MKTs can be configured despite what RFC5925 says. This is considered "misconfiguration by userspace" and it would make sense for the kernel to be more aggressive here. Some testing support is included in nettest and fcnal-test.sh, similar to the current level of tcp-md5 testing. A more elaborate test suite using pytest and scapy is available out of tree: https://github.com/cdleonard/tcp-authopt-test There is an automatic system that runs that test suite in vagrant in gitlab-ci: https://gitlab.com/cdleonard/vagrantcpao That test suite fully covers the ABI of this patchset. Changes for frr (obsolete): https://github.com/FRRouting/frr/pull/9442 That PR was made early for ABI feedback, it has many issues. Changes for yabgp (obsolete): https://github.com/cdleonard/yabgp/commits/tcp_authopt This was used for interoperability testing with cisco. Would need updates for global keys to avoid leaks. Changes since PATCH v7: * Add lifetime fields to struct tcp_authopt_key * Fix not checking MD5 after unexpected AO. Link to v7: https://lore.kernel.org/netdev/cover.1660852705.git.cdleonard@gmail.com/ Changes since PATCH v6: * Squash "remove unused noops" patch (forgot to do this before v5 send). * Make TCP_REPAIR_AUTHOPT fail if (!tp->repair) * Add {snd,rcv}_seq to struct tcp_repair_authopt next to {snd,rcv}_sne. The fact that internally snd_sne is maintained as a 64-bit extension of sne_nxt is a problem for TCP_REPAIR implementation in userspace which might not have access to snd_nxt during live traffic. By exposing a full 64-bit “recent sequence number” to userspace it's possible to ignore which exact SEQ number the SNE value is an extension of. * Fix ipv6_addr_is_prefix helper; it was incorrect and dependant on uninitialized stack memory. This was caught by test suite after many rebases. * Implement ipv4-mapped-ipv6 support, request by Eric Dumazet Link: https://lore.kernel.org/netdev/cover.1658815925.git.cdleonard@gmail.com/ Changes since PATCH v5: * Rebased on recent net-next, including recent changes refactoring md5 * Use to skb_drop_reason * Fix using sock_kmalloc for key alloc but regular kfree for free. Use kmalloc because keys are global * Fix mentioning non-existent copy_from_sockopt in doc for _copy_from_sockptr_tolerant * If no valid keys are available for a destination then report a socket error instead of sending unsigned traffic * Remove several noop implementations which are always called from ifdef * Fix build issues in all scenarios, including -Werror at every point. * Split "tcp: Refactor tcp_inbound_md5_hash into tcp_inbound_sig_hash" into a separate commit. * Add TCP_AUTHOPT_FLAG_ACTIVE to distinguish between "keys configured for socket" and "connection authenticated". A listen socket with authentication enabled will return other sockets with authentication enabled on accept() but if no key is configured for the peer then authentication will be inactive. * Add support for TCP_REPAIR_AUTHOPT new sockopts which loads/saves the AO-specific information. Link: https://lore.kernel.org/netdev/cover.1643026076.git.cdleonard@gmail.com/ Changes since PATCH v4: * Move the traffic_key context_bytes header to stack. If it's a constant string then ahash can fail unexpectedly. * Fix allowing unsigned traffic if all keys are marked norecv. * Fix crashing in __tcp_authopt_alg_init on failure. * Try to respect the rnextkeyid from SYN on SYNACK (new patch) * Fix incorrect check for TCP_AUTHOPT_KEY_DEL in __tcp_authopt_select_key * Improve docs on __tcp_authopt_select_key * Fix build with CONFIG_PROC_FS=n (kernel build robot) * Fix build with CONFIG_IPV6=n (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1640273966.git.cdleonard@gmail.com/ Changes since PATCH v3: * Made keys global (per-netns rather than per-sock). * Add /proc/net/tcp_authopt with a table of keys (not sockets). * Fix part of the shash/ahash conversion having slipped from patch 3 to patch 5 * Fix tcp_parse_sig_options assigning NULL incorrectly when both MD5 and AO are disabled (kernel build robot) * Fix sparse endianness warnings in prefix match (kernel build robot) * Fix several incorrect RCU annotations reported by sparse (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1638962992.git.cdleonard@gmail.com/ Changes since PATCH v2: * Protect tcp_authopt_alg_get/put_tfm with local_bh_disable instead of preempt_disable. This caused signature corruption when send path executing with BH enabled was interrupted by recv. * Fix accepted keyids not configured locally as "unexpected". If any key is configured that matches the peer then traffic MUST be signed. * Fix issues related to sne rollover during handshake itself. (Francesco) * Implement and test prefixlen (David) * Replace shash with ahash and reuse some of the MD5 code (Dmitry) * Parse md5+ao options only once in the same function (Dmitry) * Pass tcp_authopt_info into inbound check path, this avoids second rcu dereference for same packet. * Pass tcp_request_socket into inbound check path instead of just listen socket. This is required for SNE rollover during handshake and clearifies ISN handling. * Do not allow disabling via sysctl after enabling once, this is difficult to support well (David) * Verbose check for sysctl_tcp_authopt (Dmitry) * Use netif_index_is_l3_master (David) * Cleanup ipvx_addr_match (David) * Add a #define tcp_authopt_needed to wrap static key usage because it looks nicer. * Replace rcu_read_lock with rcu_dereference_protected in SNE updates (Eric) * Remove test suite Link: https://lore.kernel.org/netdev/cover.1635784253.git.cdleonard@gmail.com/ Changes since PATCH v1: * Implement Sequence Number Extension * Implement l3index for vrf: TCP_AUTHOPT_KEY_IFINDEX as equivalent of TCP_MD5SIG_FLAG_IFINDEX * Expand TCP-AO tests in fcnal-test.sh to near-parity with md5. * Show addr/port on failure similar to md5 * Remove tox dependency from test suite (create venv directly) * Switch default pytest output format to TAP (kselftest standard) * Fix _copy_from_sockptr_tolerant stack corruption on short sockopts. This was covered in test but error was invisible without STACKPROTECTOR=y * Fix sysctl_tcp_authopt check in tcp_get_authopt_val before memset. This was harmless because error code is checked in getsockopt anyway. * Fix dropping md5 packets on all sockets with AO enabled * Fix checking (key->recv_id & TCP_AUTHOPT_KEY_ADDR_BIND) instead of key->flags in tcp_authopt_key_match_exact * Fix PATCH 1/19 not compiling due to missing "int err" declaration * Add ratelimited message for AO and MD5 both present * Export all symbols required by CONFIG_IPV6=m (again) * Fix compilation with CONFIG_TCP_AUTHOPT=y CONFIG_TCP_MD5SIG=n * Fix checkpatch issues * Pass -rrequirements.txt to tox to avoid dependency variation. Link: https://lore.kernel.org/netdev/cover.1632240523.git.cdleonard@gmail.com/ Changes since RFCv3: * Implement TCP_AUTHOPT handling for timewait and reset replies. Write tests to execute these paths by injecting packets with scapy * Handle combining md5 and authopt: if both are configured use authopt. * Fix locking issues around send_key, introduced in on of the later patches. * Handle IPv4-mapped-IPv6 addresses: it used to be that an ipv4 SYN sent to an ipv6 socket with TCP-AO triggered WARN * Implement un-namespaced sysctl disabled this feature by default * Allocate new key before removing any old one in setsockopt (Dmitry) * Remove tcp_authopt_key_info.local_id because it's no longer used (Dmitry) * Propagate errors from TCP_AUTHOPT getsockopt (Dmitry) * Fix no-longer-correct TCP_AUTHOPT_KEY_DEL docs (Dmitry) * Simplify crypto allocation (Eric) * Use kzmalloc instead of __GFP_ZERO (Eric) * Add static_key_false tcp_authopt_needed (Eric) * Clear authopt_info copied from oldsk in __tcp_authopt_openreq (Eric) * Replace memcmp in ipv4 and ipv6 addr comparisons (Eric) * Export symbols for CONFIG_IPV6=m (kernel test robot) * Mark more functions static (kernel test robot) * Fix build with CONFIG_PROVE_RCU_LIST=y (kernel test robot) Link: https://lore.kernel.org/netdev/cover.1629840814.git.cdleonard@gmail.com/ Changes since RFCv2: * Removed local_id from ABI and match on send_id/recv_id/addr * Add all relevant out-of-tree tests to tools/testing/selftests * Return an error instead of ignoring unknown flags, hopefully this makes it easier to extend. * Check sk_family before __tcp_authopt_info_get_or_create in tcp_set_authopt_key * Use sock_owned_by_me instead of WARN_ON(!lockdep_sock_is_held(sk)) * Fix some intermediate build failures reported by kbuild robot * Improve documentation Link: https://lore.kernel.org/netdev/cover.1628544649.git.cdleonard@gmail.com/ Changes since RFC: * Split into per-topic commits for ease of review. The intermediate commits compile with a few "unused function" warnings and don't do anything useful by themselves. * Add ABI documention including kernel-doc on uapi * Fix lockdep warnings from crypto by creating pools with one shash for each cpu * Accept short options to setsockopt by padding with zeros; this approach allows increasing the size of the structs in the future. * Support for aes-128-cmac-96 * Support for binding addresses to keys in a way similar to old tcp_md5 * Add support for retrieving received keyid/rnextkeyid and controling the keyid/rnextkeyid being sent.

[PATCH] selftests/tls: Fix tls selftests dependency to correct algorithm

by Tianjia Zhang

Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") moves the SM3 and SM4 stand-alone library and the algorithm implementation for the Crypto API into the same directory, and the corresponding relationship of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the algorithm implementation for the Crypto API. Therefore, it is necessary for this module to depend on the correct algorithm. Fixes: d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") Cc: Jason A.

[PATCH v4 net-next 8/8] selftests: Add a basic HSR test.

by Sebastian Andrzej Siewior

This test adds a basic HSRv0 network with 3 nodes. In its current shape it sends and forwards packets, announcements and so merges nodes based on MAC A/B information. It is able to detect duplicate packets and packetloss should any occur.

[PATCH bpf v2 0/5] bpf: Support kernel function call in 32-bit ARM

by Yang Jihong

1. Patch1 is dependent patch to fix zext extension error in 32-bit ARM. 2. Patch2 and patch3 solve the problem that the bpf check fails because load's mem size is modified in CO_RE from the kernel and user modes, Currently, there are different opinions and a final solution needs to be selected. 3. Patch4 supports bpf fkunc in 32-bit ARM for EABI. 4. Patch5 is used to add test cases to cover some parameter scenarios states by AAPCS. The following is the test_progs result in the 32-bit ARM environment: # uname -m armv7l # echo 1 > /proc/sys/net/core/bpf_jit_enable # ./test_progs -t kfunc_call #1/1 kfunc_call/kfunc_syscall_test_fail:OK #1/2 kfunc_call/kfunc_syscall_test_null_fail:OK #1/3 kfunc_call/kfunc_call_test_get_mem_fail_rdonly:OK #1/4 kfunc_call/kfunc_call_test_get_mem_fail_use_after_free:OK #1/5 kfunc_call/kfunc_call_test_get_mem_fail_oob:OK #1/6 kfunc_call/kfunc_call_test_get_mem_fail_not_const:OK #1/7 kfunc_call/kfunc_call_test_mem_acquire_fail:OK #1/8 kfunc_call/kfunc_call_test1:OK #1/9 kfunc_call/kfunc_call_test2:OK #1/10 kfunc_call/kfunc_call_test4:OK #1/11 kfunc_call/kfunc_call_test_ref_btf_id:OK #1/12 kfunc_call/kfunc_call_test_get_mem:OK #1/13 kfunc_call/kfunc_syscall_test:OK #1/14 kfunc_call/kfunc_syscall_test_null:OK #1/17 kfunc_call/destructive:OK Yang Jihong (5): bpf: Adapt 32-bit return value kfunc for 32-bit ARM when zext extension bpf: Adjust sk size check for sk in bpf_skb_is_valid_access for CO_RE in 32-bit arch libbpf: Skip adjust mem size for load pointer in 32-bit arch in CO_RE bpf: Add kernel function call support in 32-bit ARM for EABI bpf:selftests: Add kfunc_call test for mixing 32-bit and 64-bit parameters arch/arm/net/bpf_jit_32.c | 142 ++++++++++++++++++ kernel/bpf/verifier.c | 3 + net/bpf/test_run.c | 18 +++ net/core/filter.c | 8 +- tools/lib/bpf/libbpf.c | 34 ++++- .../selftests/bpf/prog_tests/kfunc_call.c | 3 + .../selftests/bpf/progs/kfunc_call_test.c | 52 +++++++ 7 files changed, 254 insertions(+), 6 deletions(-) -- 2.30.GIT

I would also as a part of this series rename the kunit_suite from "drm_test_pick_cmdline_test_suite" to "drm_test_modeset_test_suite" or something like that.

So it would make sense for kunit to have helpers to manage platform drivers and devices.

[PATCH v3 1/3] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs. Signed-off-by: David Gow <davidgow(a)google.com> --- This should be a no-op (other than a possible performance improvement) functionality-wise, and lays the groundwork for a more optimised static stub implementation. The remaining patches in the series add a kunit_get_current_test() function which is a more friendly and performant wrapper around current->kunit_test, and use this in the slub test. They also improve the documentation a bit. If there are no objections, we'll take the whole series via the KUnit tree.

[RFC PATCH 00/11] implement DAMOS filtering for anon pages and

by SeongJae Park

DAMOS let users do system operations in a data access pattern oriented way. The data access pattern, which is extracted by DAMON, is somewhat accurate more than what user space could know in many cases. However, in some situation, users could know something more than the kernel about the pattern or some special requirements for some types of memory or processes. For example, some users would have slow swap devices and knows latency-ciritical processes and therefore want to use DAMON-based proactive reclamation (DAMON_RECLAIM) for only non-anonymous pages of non-latency-critical processes. For such restriction, users could exclude the memory regions from the initial monitoring regions and use non-dynamic monitoring regions update monitoring operations set including fvaddr and paddr. They could also adjust the DAMOS target access pattern. For dynamically changing memory layout and access pattern, those would be not enough. To help the case, add an interface, namely DAMOS filters, which can be used to avoid the DAMOS actions be applied to specific types of memory, to DAMON kernel API (damon.h). At the moment, it supports filtering anonymous pages and/or specific memory cgroups in or out for each DAMOS scheme. This patchset adds the support for all DAMOS actions that 'paddr' monitoring operations set supports ('pageout', 'lru_prio', and 'lru_deprio'), and the functionality is exposed via DAMON kernel API (damon.h) the DAMON sysfs interface (/sys/kernel/mm/damon/admins/), and DAMON_RECLAIM module parameters. Patches Sequence ---------------- First patch implements DAMOS filter interface to DAMON kernel API. Second patch makes the physical address space monitoring operations set to support the filters from all supporting DAMOS actions. Third patch adds anonymous pages filter support to DAMON_RECLAIM, and the fourth patch documents the DAMON_RECLAIM's new feature. Fifth to seventh patches implement DAMON sysfs files for support of the filters, and eighth patch connects the file to use DAMOS filters feature. Ninth patch adds simple self test cases for DAMOS filters of the sysfs interface. Finally, following two patches (tenth and eleventh) document the new features and interfaces.

WARNING: modpost: suppressed 17 unresolved symbol warnings because there were too many) Most of those are just the need to export some symbols.

The only other thing which has me a little confused is the naming of some of the functions, specifically with the __ prefix. Is it just for internal functions (many of them aren't static, but maybe they could use the VISIBLE_IF_KUNIT macro if that makes sense), or for versions of functions which accept extra arguments? Not a big deal (and maybe it's a DRM naming convention I'm ignorant of), but I couldn't quite find a pattern on my first read through. But on the whole, these look good from a KUnit point-of-view. It's really to see some solid mocking and driver testing, too. There would be ways to avoid passing the 'struct kunit' around in more places (or to store extra data as a kunit_resource), but I think it's better overall to pass it around like you have in this case -- it's certainly more compatible with things which might span threads (e.g. the workqueues). Thanks a bunch, -- David

[PATCH v2 1/2] KVM: selftests: Have perf_test_util signal when to stop vCPUs

by Oliver Upton

Signal that a test run is complete through perf_test_args instead of having tests open code a similar solution. Ensure that the field resets to false at the beginning of a test run as the structure is reused between test runs, eliminating a couple of bugs: access_tracking_perf_test hangs indefinitely on a subsequent test run, as 'done' remains true. The bug doesn't amount to much right now, as x86 supports a single guest mode. However, this is a precondition of enabling the test for other architectures with >1 guest mode, like arm64. memslot_modification_stress_test has the exact opposite problem, where subsequent test runs complete immediately as 'run_vcpus' remains false.

[PATCH v2 1/2] kunit: tool: parse KTAP compliant test output

by Rae Moar

Change the KUnit parser to be able to parse test output that complies with the KTAP version 1 specification format found here: https://kernel.org/doc/html/latest/dev-tools/ktap.html. Ensure the parser is able to parse tests with the original KUnit test output format as well. KUnit parser now accepts any of the following test output formats: Original KUnit test output format: TAP version 14 1..1 # Subtest: kunit-test-suite 1..3 ok 1 - kunit_test_1 ok 2 - kunit_test_2 ok 3 - kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 - kunit-test-suite KTAP version 1 test output format: KTAP version 1 1..1 KTAP version 1 1..3 ok 1 kunit_test_1 ok 2 kunit_test_2 ok 3 kunit_test_3 ok 1 kunit-test-suite New KUnit test output format (changes made in the next patch of this series): KTAP version 1 1..1 KTAP version 1 # Subtest: kunit-test-suite 1..3 ok 1 kunit_test_1 ok 2 kunit_test_2 ok 3 kunit_test_3 # kunit-test-suite: pass:3 fail:0 skip:0 total:3 # Totals: pass:3 fail:0 skip:0 total:3 ok 1 kunit-test-suite Signed-off-by: Rae Moar <rmoar(a)google.com> Reviewed-by: Daniel Latypov <dlatypov(a)google.com> Reviewed-by: David Gow <davidgow(a)google.com> --- Changes since v1: https://lore.kernel.org/all/20221104194705.3245738-2-rmoar@google.com/ - Switch order of patches to make changes to the parser before making changes to the test output - Change placeholder label for test header from “Test suite” to empty string - Change parser to approve the new KTAP version line in the subtest header to be before the subtest header line rather than after. - Note: Considered changing parser to allow for the top-level of testing to have a '# Subtest' line as discussed in v1 but this breaks the missing test plan test.

[PATCH] kselftest/cgroup: Add cleanup() to test_cpuset_prs.sh

by Kamalesh Babulal

Install a cleanup function using the trap command for signals EXIT, SIGINT, SIGQUIT and SIGABRT. The cleanup function will perform: 1. Online the CPUs that were made offline during the test. 2. Removing the cgroups created. 3. Restoring the original /sys/kernel/debug/sched/verbose value, currently it's left turned on, irrespective of the original configuration value. the test performs steps 1 and 2, on the successful runs, but not during all of the failed runs. With the cleanup(), the system will perform all three steps during failed/passed test runs.

[PATCH RFC 00/19] mm/gup: remove FOLL_FORCE usage from drivers (reliable R/O long-term pinning)

by David Hildenbrand

For now, we did not support reliable R/O long-term pinning in COW mappings. That means, if we would trigger R/O long-term pinning in MAP_PRIVATE mapping, we could end up pinning the (R/O-mapped) shared zeropage or a pagecache page. The next write access would trigger a write fault and replace the pinned page by an exclusive anonymous page in the process page table; whatever the process would write to that private page copy would not be visible by the owner of the previous page pin: for example, RDMA could read stale data. The end result is essentially an unexpected and hard-to-debug memory corruption. Some drivers tried working around that limitation by using "FOLL_FORCE|FOLL_WRITE|FOLL_LONGTERM" for R/O long-term pinning for now. FOLL_WRITE would trigger a write fault, if required, and break COW before pinning the page. FOLL_FORCE is required because the VMA might lack write permissions, and drivers wanted to make that working as well, just like one would expect (no write access, but still triggering a write access to break COW). However, that is not a practical solution, because (1) Drivers that don't stick to that undocumented and debatable pattern would still run into that issue. For example, VFIO only uses FOLL_LONGTERM for R/O long-term pinning. (2) Using FOLL_WRITE just to work around a COW mapping + page pinning limitation is unintuitive. FOLL_WRITE would, for example, mark the page softdirty or trigger uffd-wp, even though, there actually isn't going to be any write access. (3) The purpose of FOLL_FORCE is debug access, not access without lack of VMA permissions by arbitrarty drivers. So instead, make R/O long-term pinning work as expected, by breaking COW in a COW mapping early, such that we can remove any FOLL_FORCE usage from drivers. More details in patch #8. Patches #1--#3 add COW tests for non-anonymous pages. Patches #4--#7 prepare core MM for extended FAULT_FLAG_UNSHARE support in COW mappings. Patch #8 implements reliable R/O long-term pinning in COW mappings Patches #9--#19 remove any FOLL_FORCE usage from drivers. I'm refraining from CCing all driver maintainers on the whole patch set.

[PATCH net-next] selftests: net: Add cross-compilation support for BPF programs

by Björn Töpel

From: Björn Töpel <bjorn(a)rivosinc.com> The selftests/net does not have proper cross-compilation support, and does not properly state libbpf as a dependency.

Signed-off-by: Björn Töpel <bjorn(a)rivosinc.com> --- Now that BPF builds are starting to show up in more places (selftests/net, and soon selftests/hid), maybe it would be cleaner to move parts of the BPF builds to lib.mk?

[PATCH] kunit: tool: make --json do nothing if --raw_ouput is set

by Daniel Latypov

When --raw_output is set (to any value), we don't actually parse the test results. So asking to print the test results as json doesn't make sense. We internally create a fake test with one passing subtest, so --json would actually print out something misleading. This patch: * Rewords the flag descriptions so hopefully this is more obvious. * Also updates --raw_output's description to note the default behavior is to print out only "KUnit" results (actually any KTAP results) * also renames and refactors some related logic for clarity (e.g. test_result => test, it's a kunit_parser.Test object). Notably, this patch does not make it an error to specify --json and --raw_output together. This is an edge case, but I know of at least one wrapper around kunit.py that always sets --json. You'd never be able to use --raw_output with that wrapper.

[PATCH v2 0/9] nSVM: Security and correctness fixes

by Maxim Levitsky

Recently while trying to fix some unit tests I found a CVE in SVM nested code. In 'shutdown_interception' vmexit handler we call kvm_vcpu_reset. However if running nested and L1 doesn't intercept shutdown, we will still end up running this function and trigger a bug in it. The bug is that this function resets the 'vcpu->arch.hflags' without properly leaving the nested state, which leaves the vCPU in inconsistent state, which later triggers a kernel panic in SVM code. The same bug can likely be triggered by sending INIT via local apic to a vCPU which runs a nested guest. On VMX we are lucky that the issue can't happen because VMX always intercepts triple faults, thus triple fault in L2 will always be redirected to L1. Plus the 'handle_triple_fault' of VMX doesn't reset the vCPU. INIT IPI can't happen on VMX either because INIT events are masked while in VMX mode. First 4 patches in this series address the above issue, and are already posted on the list with title, ('nSVM: fix L0 crash if L2 has shutdown condtion which L1 doesn't intercept') I addressed the review feedback and also added a unit test to hit this issue. In addition to these patches I noticed that KVM doesn't honour SHUTDOWN intercept bit of L1 on SVM, and I included a fix to do so - its only for correctness as a normal hypervisor should always intercept SHUTDOWN. A unit test on the other hand might want to not do so. I also extendted the triple_fault_test selftest to hit this issue. Finaly I found another security issue, I found a way to trigger a kernel non rate limited printk on SVM from the guest, and last patch in the series fixes that. A unit test I posted to kvm-unit-tests project hits this issue, so no selftest was added.

[PATCH] selftests/net: Find nettest in current directory

by Daniel Díaz

The `nettest` binary, built from `selftests/net/nettest.c`, was expected to be found in the path during test execution of `fcnal-test.sh` and `pmtu.sh`, leading to tests getting skipped when the binary is not installed in the system, as can be seen in these logs found in the wild [1]: # TEST: vti4: PMTU exceptions [SKIP] [ 350.600250] IPv6: ADDRCONF(NETDEV_CHANGE): veth_b: link becomes ready [ 350.607421] IPv6: ADDRCONF(NETDEV_CHANGE): veth_a: link becomes ready # 'nettest' command not found; skipping tests # xfrm6udp not supported # TEST: vti6: PMTU exceptions (ESP-in-UDP) [SKIP] [ 351.605102] IPv6: ADDRCONF(NETDEV_CHANGE): veth_b: link becomes ready [ 351.612243] IPv6: ADDRCONF(NETDEV_CHANGE): veth_a: link becomes ready # 'nettest' command not found; skipping tests # xfrm4udp not supported The `unicast_extensions.sh` tests also rely on `nettest`, but it runs fine there because it looks for the binary in the current working directory [2]: The same mechanism that works for the Unicast extensions tests is here copied over to the PMTU and functional tests.

[PATCH] kunit: remove KUNIT_INIT_MEM_ASSERTION macro

by Daniel Latypov

Commit 870f63b7cd78 ("kunit: eliminate KUNIT_INIT_*_ASSERT_STRUCT macros") removed all the other macros of this type. But it raced with commit b8a926bea8b1 ("kunit: Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros"), which added another instance. Remove KUNIT_INIT_MEM_ASSERTION and just use the generic KUNIT_INIT_ASSERT macro instead. Rename the `size` arg to avoid conflicts by appending a "_" (like we did in the previous commit).

[PATCH v3 1/3] Documentation: KUnit: make usage.rst a superset of tips.rst, remove duplication

by Daniel Latypov

usage.rst had most of the content of the tips.rst page copied over. But it's missing https://www.kernel.org/doc/html/v6.0/dev-tools/kunit/tips.html#customizing-… Copy it over so we can retire tips.rst w/o losing content. And in that process, it also gained a duplicate section about how KUNIT_ASSERT_*() exit the test case early. Remove that.

[PATCH AUTOSEL 6.0 16/44] selftests/net: give more time to udpgro bg processes to complete startup

by Sasha Levin

From: Adrien Thierry <athierry(a)redhat.com> [ Upstream commit cdb525ca92b196f8916102b62431aa0d9a644ff2 ] In some conditions, background processes in udpgro don't have enough time to set up the sockets. When foreground processes start, this results in the test failing with "./udpgso_bench_tx: sendmsg: Connection refused". For instance, this happens from time to time on a Qualcomm SA8540P SoC running CentOS Stream 9.

[PATCH v1] kselftest/arm64: Use preferred form for predicate load/stores

The preferred form of the str/ldr for predicate registers with an immediate of zero is to omit the zero, and the clang built in assembler rejects the zero immediate. Drop the immediate.

[PATCH bpf-next v2] selftests/bpf: Fix error: undeclared identifier 'NF_NAT_MANIP_SRC'

by Rong Tao

From: Rong Tao <rongtao(a)cestc.cn> commit 472caa69183f("netfilter: nat: un-export nf_nat_used_tuple") introduce NF_NAT_MANIP_SRC/DST enum in include/net/netfilter/nf_nat.h, and commit b06b45e82b59("selftests/bpf: add tests for bpf_ct_set_nat_info kfunc") use NF_NAT_MANIP_SRC/DST in test_bpf_nf.c. In bpf kself-test config (tools/testing/selftests/bpf/config) nf_nat is compiled as built-in, this issue occurs just if it is compiled as module. We could use BPF CO-RE and ___suffix rule to avoid this. How to reproduce the error: $ make -C tools/testing/selftests/bpf/ ... CLNG-BPF [test_maps] test_bpf_nf.bpf.o error: use of undeclared identifier 'NF_NAT_MANIP_SRC' bpf_ct_set_nat_info(ct, &saddr, sport, NF_NAT_MANIP_SRC); ^ error: use of undeclared identifier 'NF_NAT_MANIP_DST' bpf_ct_set_nat_info(ct, &daddr, dport, NF_NAT_MANIP_DST); ^ 2 errors generated.
