[PATCH v11 0/8] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks. [1] https://lore.kernel.org/linux-iommu/20231026044216.64964-1-yi.l.liu@intel.c… - merged [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1 Change log: v11: - Drop hw_error field in vtd cache invalidation uapi. devTLB invalidation error is a serious security emergency requiring the host kernel to handle. No need to expose it to userspace (especially given existing VMs doesn't issue devTLB invalidation at all). - The vtd qi_submit_sync() and related callers are reverted back to the original state due to above drop. - Align with the vtd path, drop the hw_error reporting in mock driver and selftest as well since selftest is a demo of the real driver. - Drop iommu_respond_struct_to_user_array() since no more driver want to respond single entry in the user_array. - Two typos from Wubinbin v10: https://lore.kernel.org/all/20240102143834.146165-1-yi.l.liu@intel.com/ - Minor tweak to patch 07 (Kevin) - Rebase on top of 6.7-rc8 v9: https://lore.kernel.org/linux-iommu/20231228150629.13149-1-yi.l.liu@intel.c… - Add a test case which sets both IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in flags, and expect to succeed and see an 'error'. (Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6. Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy(). Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (2): iommu: Add cache_invalidate_user op iommu/vt-d: Add iotlb flush for nested domain Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (2): iommufd: Add IOMMU_HWPT_INVALIDATE iommufd: Add data structure for Intel VT-d stage-1 cache invalidation drivers/iommu/intel/nested.c | 88 ++++++++++ drivers/iommu/iommufd/hw_pagetable.c | 41 +++++ drivers/iommu/iommufd/iommufd_private.h | 10 ++ drivers/iommu/iommufd/iommufd_test.h | 23 +++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 76 +++++++++ include/linux/iommu.h | 79 +++++++++ include/uapi/linux/iommufd.h | 79 +++++++++ tools/testing/selftests/iommu/iommufd.c | 152 ++++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 57 +++++++ 10 files changed, 608 insertions(+) -- 2.34.1

[PATCH 00/12] selftests/net: Add TCP-AO tests

by Dmitry Safonov

Hi, An essential part of any big kernel submissions is selftests. At the beginning of TCP-AO project, I made patches to fcnal-test.sh and nettest.c to have the benefits of easy refactoring, early noticing breakages, putting a moat around the code, documenting and designing uAPI. While tests based on fcnal-test.sh/nettest.c provided initial testing* and were very easy to add, the pile of TCP-AO quickly grew out of one-binary + shell-script testing. The design of the TCP-AO testing is a bit different than one-big selftest binary as I did previously in net/ipsec.c. I found it beneficial to avoid implementing a tests runner/scheduler and delegate it to the user or Makefile. The approach is very influenced by CRIU/ZDTM testing[1]: it provides a static library with helper functions and selftest binaries that create specific scenarios. I also tried to utilize kselftest.h. test_init() function does all needed preparations. To not leave any traces after a selftest exists, it creates a network namespace and if the test wants to establish a TCP connection, a child netns. The parent and child netns have veth pair with proper ip addresses and routes set up. Both peers, the client and server are different pthreads. The treading model was chosen over forking mostly by easiness of cleanup on a failure: no need to search for children, handle SIGCHLD, make sure not to wait for a dead peer to perform anything, etc. Any thread that does exit() naturally kills the tests, sweet! The selftests are compiled currently in two variants: ipv4 and ipv6. Ipv4-mapped-ipv6 addresses might be a third variant to add, but it's not there in this version. As pretty much all tests are shared between two address families, most of the code can be shared, too. To differ in code what kind of test is running, Makefile supplies -DIPV6_TEST to compiler and ifdeffery in tests can do things that have to be different between address families. This is similar to TARGETS_C_BOTHBITS in x86 selftests and also to tests code sharing in CRIU/ZDTM. The total number of tests is 832. From them rst_ipv{4,6} has currently one flaky subtest, that may fail: > not ok 9 client connection was not reset: 0 I'll investigate what happens there. Also, unsigned-md5_ipv{4,6} are flaky because of netns counter checks: it doesn't expect that there may be retransmitted TCP segments from a previous sub-selftest. That will be fixed. Besides, key-management_ipv{4,6} has 3 sub-tests passing with XFAIL: > ok 15 # XFAIL listen() after current/rnext keys set: the socket has current/rnext keys: 100:200 > ok 16 # XFAIL listen socket, delete current key from before listen(): failed to delete the key 100:100 -16 > ok 17 # XFAIL listen socket, delete rnext key from before listen(): failed to delete the key 200:200 -16 ... > # Totals: pass:117 fail:0 xfail:3 xpass:0 skip:0 error:0 Those need some more kernel work to pass instead of xfail.

As well as their interaction with VRFs and AO_REQUIRED flag. There are certainly more test scenarios that can be added, but even so, I'm pretty happy that this much of TCP-AO functionality and uAPIs got covered. These selftests were iteratively developed by me during TCP-AO kernel upstreaming and the resulting kernel patches would have been worse without having these tests. They provided the user-side perspective but also allowed safer refactoring with less possibility of introducing a regression. Now it's time to use them to dig a moat around the TCP-AO code! There are also people from other network companies that work on TCP-AO (+testing), so sharing these selftests will allow them to contribute and may benefit from their efforts.

[PATCH v2 0/6] IOMMUFD: Deliver IO page faults to user space

by Lu Baolu

Hi folks, This series implements the functionality of delivering IO page faults to user space through the IOMMUFD framework for nested translation. Nested translation is a hardware feature that supports two-stage translation tables for IOMMU. The second-stage translation table is managed by the host VMM, while the first-stage translation table is owned by user space. This allows user space to control the IOMMU mappings for its devices. When an IO page fault occurs on the first-stage translation table, the IOMMU hardware can deliver the page fault to user space through the IOMMUFD framework. User space can then handle the page fault and respond to the device top-down through the IOMMUFD. This allows user space to implement its own IO page fault handling policies. User space indicates its capability of handling IO page faults by setting the IOMMU_HWPT_ALLOC_IOPF_CAPABLE flag when allocating a hardware page table (HWPT). IOMMUFD will then set up its infrastructure for page fault delivery. On a successful return of HWPT allocation, the user can retrieve and respond to page faults by reading and writing to the file descriptor (FD) returned in out_fault_fd. The iommu selftest framework has been updated to test the IO page fault delivery and response functionality. This series is based on the latest implementation of nested translation under discussion [1] and the page fault handling framework refactoring in the IOMMU core [2].

[PATCH 0/3] vfio-pci support pasid attach/detach

by Yi Liu

This adds the pasid attach/detach uAPIs for userspace to attach/detach a PASID of a device to/from a given ioas/hwpt. Only vfio-pci driver is enabled in this series. After this series, PASID-capable devices bound with vfio-pci can report PASID capability to userspace and VM to enable PASID usages like Shared Virtual Addressing (SVA). This series first adds the helpers for pasid attach in vfio core and then add the device cdev ioctls for pasid attach/detach, finally exposes the device PASID capability to user. It depends on iommufd pasid attach/detach series [1].

Conform the layout, informational and status messages to TAP. No functional change is intended other than the layout of output messages.

[PATCH v6 0/4] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)google.com> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections.

[PATCH bpf-next v3 0/3] Annotate kfuncs in .BTF_ids section

by Daniel Xu

=== Description === This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 3's description. The accompanying pahole changes (still needs some cleanup) can be viewed here on this "frozen" branch [0]. [0]: https://github.com/danobi/pahole/tree/kfunc_btf-mailed === Changelog === Changes from v2: * Only WARN() for vmlinux kfuncs Changes from v1: * Move WARN_ON() up a call level * Also return error when kfunc set is not properly tagged * Use BTF_KFUNCS_START/END instead of flags * Rename BTF_SET8_KFUNC to BTF_SET8_KFUNCS Daniel Xu (3): bpf: btf: Support flags for BTF_SET8 sets bpf: btf: Add BTF_KFUNCS_START/END macro pair bpf: treewide: Annotate BPF kfuncs in BTF drivers/hid/bpf/hid_bpf_dispatch.c | 8 +++---- fs/verity/measure.c | 4 ++-- include/linux/btf_ids.h | 21 +++++++++++++++---- kernel/bpf/btf.c | 8 +++++++ kernel/bpf/cpumask.c | 4 ++-- kernel/bpf/helpers.c | 8 +++---- kernel/bpf/map_iter.c | 4 ++-- kernel/cgroup/rstat.c | 4 ++-- kernel/trace/bpf_trace.c | 8 +++---- net/bpf/test_run.c | 8 +++---- net/core/filter.c | 16 +++++++------- net/core/xdp.c | 4 ++-- net/ipv4/bpf_tcp_ca.c | 4 ++-- net/ipv4/fou_bpf.c | 4 ++-- net/ipv4/tcp_bbr.c | 4 ++-- net/ipv4/tcp_cubic.c | 4 ++-- net/ipv4/tcp_dctcp.c | 4 ++-- net/netfilter/nf_conntrack_bpf.c | 4 ++-- net/netfilter/nf_nat_bpf.c | 4 ++-- net/xfrm/xfrm_interface_bpf.c | 4 ++-- net/xfrm/xfrm_state_bpf.c | 4 ++-- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 8 +++---- 22 files changed, 81 insertions(+), 60 deletions(-) -- 2.42.1

[PATCH bpf-next v2 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) v2 changes: Fixed comments in patch 1, moved endianness checks to header files in patch 12 where possible, added Eduard's ACKs.

[PATCH] selftests/livepatch: fix and refactor new dmesg message code

by Joe Lawrence

The livepatching kselftests rely on comparing expected vs. observed dmesg output. After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev <agordeev(a)linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b… Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com> --- .../testing/selftests/livepatch/functions.sh | 37 +++++++++---------- 1 file changed, 17 insertions(+), 20 deletions(-) diff --git a/tools/testing/selftests/livepatch/functions.sh b/tools/testing/selftests/livepatch/functions.sh index c8416c54b463..b1fd7362c2fe 100644 --- a/tools/testing/selftests/livepatch/functions.sh +++ b/tools/testing/selftests/livepatch/functions.sh @@ -42,17 +42,6 @@ function die() { exit 1 } -# save existing dmesg so we can detect new content -function save_dmesg() { - SAVED_DMESG=$(mktemp --tmpdir -t klp-dmesg-XXXXXX) - dmesg > "$SAVED_DMESG" -} - -# cleanup temporary dmesg file from save_dmesg() -function cleanup_dmesg_file() { - rm -f "$SAVED_DMESG" -} - function push_config() { DYNAMIC_DEBUG=$(grep '^kernel/livepatch' /sys/kernel/debug/dynamic_debug/control | \ awk -F'[: ]' '{print "file " $1 " line " $2 " " $4}') @@ -99,7 +88,6 @@ function set_ftrace_enabled() { function cleanup() { pop_config - cleanup_dmesg_file } # setup_config - save the current config and set a script exit trap that @@ -280,7 +268,15 @@ function set_pre_patch_ret { function start_test { local test="$1" - save_dmesg + # Dump something unique into the dmesg log, then stash the entry + # in LAST_DMESG.

[PATCH 0/3] Update LLVM Phabricator and Bugzilla links

by Nathan Chancellor

This series updates all instances of LLVM Phabricator and Bugzilla links to point to GitHub commits directly and LLVM's Bugzilla to GitHub issue shortlinks respectively. I split up the Phabricator patch into BPF selftests and the rest of the kernel in case the BPF folks want to take it separately from the rest of the series, there are obviously no dependency issues in that case. The Bugzilla change was mechanical enough and should have no conflicts. I am aiming this at Andrew and CC'ing other lists, in case maintainers want to chime in, but I think this is pretty uncontroversial (famous last words...). --- Nathan Chancellor (3): selftests/bpf: Update LLVM Phabricator links arch and include: Update LLVM Phabricator links treewide: Update LLVM Bugzilla links arch/arm64/Kconfig | 4 +-- arch/powerpc/Makefile | 4 +-- arch/powerpc/kvm/book3s_hv_nested.c | 2 +- arch/riscv/Kconfig | 2 +- arch/riscv/include/asm/ftrace.h | 2 +- arch/s390/include/asm/ftrace.h | 2 +- arch/x86/power/Makefile | 2 +- crypto/blake2b_generic.c | 2 +- drivers/firmware/efi/libstub/Makefile | 2 +- drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c | 2 +- drivers/media/test-drivers/vicodec/codec-fwht.c | 2 +- drivers/regulator/Kconfig | 2 +- include/asm-generic/vmlinux.lds.h | 2 +- include/linux/compiler-clang.h | 2 +- lib/Kconfig.kasan | 2 +- lib/raid6/Makefile | 2 +- lib/stackinit_kunit.c | 2 +- mm/slab_common.c | 2 +- net/bridge/br_multicast.c | 2 +- security/Kconfig | 2 +- tools/testing/selftests/bpf/README.rst | 32 +++++++++++----------- tools/testing/selftests/bpf/prog_tests/xdpwall.c | 2 +- .../selftests/bpf/progs/test_core_reloc_type_id.c | 2 +- 23 files changed, 40 insertions(+), 40 deletions(-) --- base-commit: 0dd3ee31125508cd67f7e7172247f05b7fd1753a change-id: 20240109-update-llvm-links-d03f9d649e1e Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[PATCH V13 0/7] amd-pstate preferred core

by Meng Li

Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach maximum frequency. To find the best process scheduling policy for a given scenario, OS needs to know the core ordering informed by the platform through highest performance capability register of the CPPC interface. Earlier implementations of amd-pstate preferred core only support a static core ranking and targeted performance. Now it has the ability to dynamically change the preferred core based on the workload and platform conditions and accounting for thermals and aging. Amd-pstate driver utilizes the functions and data structures provided by the ITMT architecture to enable the scheduler to favor scheduling on cores which can be get a higher frequency with lower voltage. We call it amd-pstate preferred core. Here sched_set_itmt_core_prio() is called to set priorities and sched_set_itmt_support() is called to enable ITMT feature. Amd-pstate driver uses the highest performance value to indicate the priority of CPU. The higher value has a higher priority. Amd-pstate driver will provide an initial core ordering at boot time. It relies on the CPPC interface to communicate the core ranking to the operating system and scheduler to make sure that OS is choosing the cores with highest performance firstly for scheduling the process. When amd-pstate driver receives a message with the highest performance change, it will update the core ranking. Changes from V12->V13: - ACPI: CPPC: - - modify commit message. - - modify handle function of the notify(0x85). - cpufreq: amd-pstate: - - implement update_limits() callback function. - x86: - - pick up Acked-By flag added by Petkov.

by Christoph Muellner

From: Christoph Müllner <christoph.muellner(a)vrull.eu> When building the RISC-V selftests with a riscv32 compiler I ran into a couple of compiler warnings. While riscv32 support for these tests is questionable, the fixes are so trivial that it is probably best to simply apply them.

[PATCH v2] KVM: selftests: Fix the dirty_log_test semaphore imbalance

by Shaoqin Huang

When execute the dirty_log_test on some aarch64 machine, it sometimes trigger the ASSERT: ==== Test Assertion Failure ==== dirty_log_test.c:384: dirty_ring_vcpu_ring_full pid=14854 tid=14854 errno=22 - Invalid argument 1 0x00000000004033eb: dirty_ring_collect_dirty_pages at dirty_log_test.c:384 2 0x0000000000402d27: log_mode_collect_dirty_pages at dirty_log_test.c:505 3 (inlined by) run_test at dirty_log_test.c:802 4 0x0000000000403dc7: for_each_guest_mode at guest_modes.c:100 5 0x0000000000401dff: main at dirty_log_test.c:941 (discriminator 3) 6 0x0000ffff9be173c7: ?? ??:0 7 0x0000ffff9be1749f: ?? ??:0 8 0x000000000040206f: _start at ??:? Didn't continue vcpu even without ring full The dirty_log_test fails when execute the dirty-ring test, this is because the sem_vcpu_cont and the sem_vcpu_stop is non-zero value when execute the dirty_ring_collect_dirty_pages() function. When those two sem_t variables are non-zero, the dirty_ring_wait_vcpu() at the beginning of the dirty_ring_collect_dirty_pages() will not wait for the vcpu to stop, but continue to execute the following code. In this case, before vcpu stop, if the dirty_ring_vcpu_ring_full is true, and the dirty_ring_collect_dirty_pages() has passed the check for the dirty_ring_vcpu_ring_full but hasn't execute the check for the continued_vcpu, the vcpu stop, and set the dirty_ring_vcpu_ring_full to false. Then dirty_ring_collect_dirty_pages() will trigger the ASSERT. Why sem_vcpu_cont and sem_vcpu_stop can be non-zero value? It's because the dirty_ring_before_vcpu_join() execute the sem_post(&sem_vcpu_cont) at the end of each dirty-ring test. It can cause two cases: 1. sem_vcpu_cont be non-zero. When we set the host_quit to be true, the vcpu_worker directly see the host_quit to be true, it quit. So the log_mode_before_vcpu_join() function will set the sem_vcpu_cont to 1, since the vcpu_worker has quit, it won't consume it. 2. sem_vcpu_stop be non-zero. When we set the host_quit to be true, the vcpu_worker has entered the guest state, the next time it exit from guest state, it will set the sem_vcpu_stop to 1, and then see the host_quit, no one will consume the sem_vcpu_stop. When execute more and more dirty-ring tests, the sem_vcpu_cont and sem_vcpu_stop can be larger and larger, which makes many code paths don't wait for the sem_t. Thus finally cause the problem. To fix this problem, we can wait a while before set the host_quit to true, which gives the vcpu time to enter the guest state, so it will exit again. Then we can wait the vcpu to exit, and let it continue again, then the vcpu will see the host_quit. Thus the sem_vcpu_cont and sem_vcpu_stop will be both zero when test finished.

[PATCH] selftests/net/tcp-ao: Use LDLIBS instead of LDFLAGS

by Dmitry Safonov

The rules to link selftests are: > $(OUTPUT)/%_ipv4: %.c > $(LINK.c) $^ $(LDLIBS) -o $@ > > $(OUTPUT)/%_ipv6: %.c > $(LINK.c) -DIPV6_TEST $^ $(LDLIBS) -o $@ The intel test robot uses only selftest's Makefile, not the top linux Makefile: > make W=1 O=/tmp/kselftest -C tools/testing/selftests So, $(LINK.c) is determined by environment, rather than by kernel Makefiles. On my machine (as well as other people that ran tcp-ao selftests) GNU/Make implicit definition does use $(LDFLAGS): > [dima@Mindolluin ~]$ make -p -f/dev/null | grep '^LINK.c\>' > make: *** No targets. Stop. > LINK.c = $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH) But, according to build robot report, it's not the case for them. While I could just avoid using pre-defined $(LINK.c), it's also used by selftests/lib.mk by default. Anyways, according to GNU/Make documentation [1], I should have used $(LDLIBS) instead of $(LDFLAGS) in the first place, so let's just do it: > LDFLAGS > Extra flags to give to compilers when they are supposed to invoke > the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added > to the LDLIBS variable instead. > LDLIBS > Library flags or names given to compilers when they are supposed > to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still > supported) alternative to LDLIBS. Non-library linker flags, such > as -L, should go in the LDFLAGS variable.

Re: [PATCH v14 10/12] selftests/landlock: Add network tests

by Muhammad Usama Anjum

Hi Konstantin, There are some errors being reported in KernelCI: https://linux.kernelci.org/test/plan/id/657ab2240c761c0bd1e134ee/ The following sub-tests are failing: landlock_net_test_protocol_no_sandbox_with_ipv6_tcp_bind_unspec landlock_net_test_protocol_no_sandbox_with_ipv6_udp_bind_unspec landlock_net_test_protocol_tcp_sandbox_with_ipv6_udp_bind_unspec From my initial investigation, I can see that these failures are coming from just finding the wrong return error code (-97 instead of -22). It may be test's issue or the kernel's, not sure yet.

[PATCH v5 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

Changes in v5: * Fixed an issue found by Joe that copied Kbuild files along with the test modules to the installation directory. * Added Joe Lawrense review tags. Changes in v4: * Documented how to compile the livepatch selftests without running the tests (Joe) * Removed the mention to lib/livepatch on MAINTAINERS file, reported by checkpatch. Changes in v3: * Rebased on top of v6.6-rc5 * The commits messages were improved (Thanks Petr!) * Created TEST_GEN_MODS_DIR variable to point to a directly that contains kernel modules, and adapt selftests to build it before running the test. * Moved test_klp-call_getpid out of test_programs, since the gen_tar would just copy the generated test programs to the livepatches dir, and so scripts relying on test_programs/test_klp-call_getpid will fail. * Added a module_param for klp_pids, describing it's usage. * Simplified the call_getpid program to ignore the return of getpid syscall, since we only want to make sure the process transitions correctly to the patched stated * The test-syscall.sh not prints a log message showing the number of remaining processes to transition into to livepatched state, and check_output expects it to be 0. * Added MODULE_AUTHOR and MODULE_DESCRIPTION to test_klp_syscall.c - Link to v3: https://lore.kernel.org/r/20231031-send-lp-kselftests-v3-0-2b1655c2605f@sus… - Link to v2: https://lore.kernel.org/linux-kselftest/20220630141226.2802-1-mpdesouza@sus… This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. Thanks in advance!

[PATCH V12 0/7] amd-pstate preferred core

by Meng Li

Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach maximum frequency. To find the best process scheduling policy for a given scenario, OS needs to know the core ordering informed by the platform through highest performance capability register of the CPPC interface. Earlier implementations of amd-pstate preferred core only support a static core ranking and targeted performance. Now it has the ability to dynamically change the preferred core based on the workload and platform conditions and accounting for thermals and aging. Amd-pstate driver utilizes the functions and data structures provided by the ITMT architecture to enable the scheduler to favor scheduling on cores which can be get a higher frequency with lower voltage. We call it amd-pstate preferred core. Here sched_set_itmt_core_prio() is called to set priorities and sched_set_itmt_support() is called to enable ITMT feature. Amd-pstate driver uses the highest performance value to indicate the priority of CPU. The higher value has a higher priority. Amd-pstate driver will provide an initial core ordering at boot time. It relies on the CPPC interface to communicate the core ranking to the operating system and scheduler to make sure that OS is choosing the cores with highest performance firstly for scheduling the process. When amd-pstate driver receives a message with the highest performance change, it will update the core ranking. Changes from V11->V12: - all: - - pick up Reviewed-By flag added by Perry. - cpufreq: amd-pstate: - - rebase the latest linux-next and fixed conflicts. - - fixed the issue about cpudata without init in amd_pstate_update_highest_perf(). Changes from V10->V11: - cpufreq: amd-pstate: - - according Perry's commnts, I replace the string with str_enabled_disable(). Changes from V9->V10: - cpufreq: amd-pstate: - - add judgement for highest_perf. When it is less than 255, the preferred core feature is enabled. And it will set the priority. - - deleset "static u32 max_highest_perf" etc, because amd p-state perferred coe does not require specail process for hotpulg.

[PATCH v8 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

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

The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy().

[RFC PATCH v5 0/4] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections. Change history: =============== V5: - fix build issue in mseal-Wire-up-mseal-syscall (Suggested by Linus Torvalds, and Greg KH) - updates on selftest. V4: (Suggested by Linus Torvalds) - new signature: mseal(start,len,flags) - 32 bit is not supported. vm_seal is removed, use vm_flags instead. - single bit in vm_flags for sealed state. - CONFIG_MSEAL kernel config is removed. - single bit of PROT_SEAL in the "Prot" field of mmap(). Other changes: - update selftest (Suggested by Muhammad Usama Anjum) - update documentation. https://lore.kernel.org/all/20240104185138.169307-1-jeffxu@chromium.org/ V3: - Abandon per-syscall approach, (Suggested by Linus Torvalds). - Organize sealing types around their functionality, such as MM_SEAL_BASE, MM_SEAL_PROT_PKEY. - Extend the scope of sealing from calls originated in userspace to both kernel and userspace. (Suggested by Linus Torvalds) - Add seal type support in mmap(). (Suggested by Pedro Falcato) - Add a new sealing type: MM_SEAL_DISCARD_RO_ANON to prevent destructive operations of madvise. (Suggested by Jann Horn and Stephen Röttger) - Make sealed VMAs mergeable. (Suggested by Jann Horn) - Add MAP_SEALABLE to mmap() - Add documentation - mseal.rst https://lore.kernel.org/linux-mm/20231212231706.2680890-2-jeffxu@chromium.o… v2: Use _BITUL to define MM_SEAL_XX type. Use unsigned long for seal type in sys_mseal() and other functions. Remove internal VM_SEAL_XX type and convert_user_seal_type(). Remove MM_ACTION_XX type. Remove caller_origin(ON_BEHALF_OF_XX) and replace with sealing bitmask. Add more comments in code.

[PATCH 1/1] selftests: mm: hugepage-vmemmap fails on 64K page size systems.

by Donet Tom

The kernel sefltest mm/hugepage-vmemmap fails on architectures which has different page size other than 4K. In hugepage-vmemmap page size used is 4k so the pfn calculation will go wrong on systems which has different page size .The length of MAP_HUGETLB memory must be hugepage aligned but in hugepage-vmemmap map length is 2M so this will not get aligned if the system has differnet hugepage size. Added psize() to get the page size and default_huge_page_size() to get the default hugepage size at run time, hugepage-vmemmap test pass on powerpc with 64K page size and x86 with 4K page size. Result on powerpc without patch (page size 64K) *# ./hugepage-vmemmap Returned address is 0x7effff000000 whose pfn is 0 Head page flags (100000000) is invalid check_page_flags: Invalid argument *# Result on powerpc with patch (page size 64K) *# ./hugepage-vmemmap Returned address is 0x7effff000000 whose pfn is 600 *# Result on x86 with patch (page size 4K) *# ./hugepage-vmemmap Returned address is 0x7fc7c2c00000 whose pfn is 1dac00 *# Signed-off-by: Donet Tom <donettom(a)linux.vnet.ibm.com> Reported-by : Geetika Moolchandani (geetika(a)linux.ibm.com) Tested-by : Geetika Moolchandani (geetika(a)linux.ibm.com) --- tools/testing/selftests/mm/hugepage-vmemmap.c | 29 ++++++++++++------- 1 file changed, 18 insertions(+), 11 deletions(-) diff --git a/tools/testing/selftests/mm/hugepage-vmemmap.c b/tools/testing/selftests/mm/hugepage-vmemmap.c index 5b354c209e93..894d28c3dd47 100644 --- a/tools/testing/selftests/mm/hugepage-vmemmap.c +++ b/tools/testing/selftests/mm/hugepage-vmemmap.c @@ -10,10 +10,7 @@ #include <unistd.h> #include <sys/mman.h> #include <fcntl.h> - -#define MAP_LENGTH (2UL * 1024 * 1024) - -#define PAGE_SIZE 4096 +#include "vm_util.h" #define PAGE_COMPOUND_HEAD (1UL << 15) #define PAGE_COMPOUND_TAIL (1UL << 16) @@ -39,6 +36,9 @@ #define MAP_FLAGS (MAP_PRIVATE | MAP_ANONYMOUS | MAP_HUGETLB) #endif +static size_t pagesize; +static size_t maplength; + static void write_bytes(char *addr, size_t length) { unsigned long i; @@ -56,7 +56,7 @@ static unsigned long virt_to_pfn(void *addr) if (fd < 0) return -1UL; - lseek(fd, (unsigned long)addr / PAGE_SIZE * sizeof(pagemap), SEEK_SET); + lseek(fd, (unsigned long)addr / pagesize * sizeof(pagemap), SEEK_SET); read(fd, &pagemap, sizeof(pagemap)); close(fd); @@ -86,7 +86,7 @@ static int check_page_flags(unsigned long pfn) * this also verifies kernel has correctly set the fake page_head to tail * while hugetlb_free_vmemmap is enabled. */ - for (i = 1; i < MAP_LENGTH / PAGE_SIZE; i++) { + for (i = 1; i < maplength / pagesize; i++) { read(fd, &pageflags, sizeof(pageflags)); if ((pageflags & TAIL_PAGE_FLAGS) != TAIL_PAGE_FLAGS || (pageflags & HEAD_PAGE_FLAGS) == HEAD_PAGE_FLAGS) { @@ -106,18 +106,25 @@ int main(int argc, char **argv) void *addr; unsigned long pfn; - addr = mmap(MAP_ADDR, MAP_LENGTH, PROT_READ | PROT_WRITE, MAP_FLAGS, -1, 0); + pagesize = psize(); + maplength = default_huge_page_size(); + if (!maplength) { + printf("Unable to determine huge page size\n"); + exit(1); + } + + addr = mmap(MAP_ADDR, maplength, PROT_READ | PROT_WRITE, MAP_FLAGS, -1, 0); if (addr == MAP_FAILED) { perror("mmap"); exit(1); } /* Trigger allocation of HugeTLB page. */ - write_bytes(addr, MAP_LENGTH); + write_bytes(addr, maplength); pfn = virt_to_pfn(addr); if (pfn == -1UL) { - munmap(addr, MAP_LENGTH); + munmap(addr, maplength); perror("virt_to_pfn"); exit(1); } @@ -125,13 +132,13 @@ int main(int argc, char **argv) printf("Returned address is %p whose pfn is %lx\n", addr, pfn); if (check_page_flags(pfn) < 0) { - munmap(addr, MAP_LENGTH); + munmap(addr, maplength); perror("check_page_flags"); exit(1); } /* munmap() length of MAP_HUGETLB memory must be hugepage aligned */ - if (munmap(addr, MAP_LENGTH)) { + if (munmap(addr, maplength)) { perror("munmap"); exit(1); } -- 2.43.0

[PATCH RESEND v4 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

Changes in v4: * Documented how to compile the livepatch selftests without running the tests (Joe) * Removed the mention to lib/livepatch on MAINTAINERS file, reported by checkpatch. Changes in v3: * Rebased on top of v6.6-rc5 * The commits messages were improved (Thanks Petr!) * Created TEST_GEN_MODS_DIR variable to point to a directly that contains kernel modules, and adapt selftests to build it before running the test. * Moved test_klp-call_getpid out of test_programs, since the gen_tar would just copy the generated test programs to the livepatches dir, and so scripts relying on test_programs/test_klp-call_getpid will fail. * Added a module_param for klp_pids, describing it's usage. * Simplified the call_getpid program to ignore the return of getpid syscall, since we only want to make sure the process transitions correctly to the patched stated * The test-syscall.sh not prints a log message showing the number of remaining processes to transition into to livepatched state, and check_output expects it to be 0. * Added MODULE_AUTHOR and MODULE_DESCRIPTION to test_klp_syscall.c - Link to v3: https://lore.kernel.org/r/20231031-send-lp-kselftests-v3-0-2b1655c2605f@sus… - Link to v2: https://lore.kernel.org/linux-kselftest/20220630141226.2802-1-mpdesouza@sus… This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. Thanks in advance!

[PATCH v2 0/4] kselftest: alsa: Fix a couple of format specifiers and function parameters

by Mirsad Todorovac

Minor fixes of compiler warnings and one bug in the number of parameters which would not crash the test but it is better fixed for correctness sake. As the general climate in the Linux kernel community is to fix all compiler warnings, this could be on the right track, even if only in the testing suite. Changelog: v1 -> v2: - Compared to v1, commit subject lines have been adjusted to reflect the style of the subsystem, as suggested by Mark. - 1/4 was already acked and unchanged (adjusted the subject line as suggested) (code unchanged) - 2/4 was acked with suggestion to adjust the subject line (done).

[PATCH v3] kunit: run test suites only after module initialization completes

by Marco Pagani

Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed a wild-memory-access bug that could have happened during the loading phase of test suites built and executed as loadable modules. However, it also introduced a problematic side effect that causes test suites modules to crash when they attempt to register fake devices. When a module is loaded, it traverses the MODULE_STATE_UNFORMED and MODULE_STATE_COMING states before reaching the normal operating state MODULE_STATE_LIVE. Finally, when the module is removed, it moves to MODULE_STATE_GOING before being released. However, if the loading function load_module() fails between complete_formation() and do_init_module(), the module goes directly from MODULE_STATE_COMING to MODULE_STATE_GOING without passing through MODULE_STATE_LIVE. This behavior was causing kunit_module_exit() to be called without having first executed kunit_module_init(). Since kunit_module_exit() is responsible for freeing the memory allocated by kunit_module_init() through kunit_filter_suites(), this behavior was resulting in a wild-memory-access bug. Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed this issue by running the tests when the module is still in MODULE_STATE_COMING. However, modules in that state are not fully initialized, lacking sysfs kobjects. Therefore, if a test module attempts to register a fake device, it will inevitably crash. This patch proposes a different approach to fix the original wild-memory-access bug while restoring the normal module execution flow by making kunit_module_exit() able to detect if kunit_module_init() has previously initialized the tests suite set. In this way, test modules can once again register fake devices without crashing. This behavior is achieved by checking whether mod->kunit_suites is a virtual or direct mapping address. If it is a virtual address, then kunit_module_init() has allocated the suite_set in kunit_filter_suites() using kmalloc_array(). On the contrary, if mod->kunit_suites is still pointing to the original address that was set when looking up the .kunit_test_suites section of the module, then the loading phase has failed and there's no memory to be freed. v3: - add a comment to clarify why the start address is checked v2: - add include <linux/mm.h> Fixes: 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") Tested-by: Richard Fitzgerald <rf(a)opensource.cirrus.com> Reviewed-by: Javier Martinez Canillas <javierm(a)redhat.com> Signed-off-by: Marco Pagani <marpagan(a)redhat.com> --- lib/kunit/test.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/lib/kunit/test.c b/lib/kunit/test.c index 7aceb07a1af9..3263e0d5e0f6 100644 --- a/lib/kunit/test.c +++ b/lib/kunit/test.c @@ -16,6 +16,7 @@ #include <linux/panic.h> #include <linux/sched/debug.h> #include <linux/sched.h> +#include <linux/mm.h> #include "debugfs.h" #include "hooks-impl.h" @@ -775,12 +776,19 @@ static void kunit_module_exit(struct module *mod) }; const char *action = kunit_action(); + /* + * Check if the start address is a valid virtual address to detect + * if the module load sequence has failed and the suite set has not + * been initialized and filtered. + */ + if (!suite_set.start || !virt_addr_valid(suite_set.start)) + return; + if (!action) __kunit_test_suites_exit(mod->kunit_suites, mod->num_kunit_suites); - if (suite_set.start) - kunit_free_suite_set(suite_set); + kunit_free_suite_set(suite_set); } static int kunit_module_notify(struct notifier_block *nb, unsigned long val, @@ -790,12 +798,12 @@ static int kunit_module_notify(struct notifier_block *nb, unsigned long val, switch (val) { case MODULE_STATE_LIVE: + kunit_module_init(mod); break; case MODULE_STATE_GOING: kunit_module_exit(mod); break; case MODULE_STATE_COMING: - kunit_module_init(mod); break; case MODULE_STATE_UNFORMED: break; base-commit: 33cc938e65a98f1d29d0a18403dbbee050dcad9a -- 2.43.0

[PATCH v7 0/3] Add Intel VT-d nested translation (part 2/2)

by Yi Liu

This is the second part to add Intel VT-d nested translation based on IOMMUFD nesting infrastructure. As the iommufd nesting infrastructure series [1], iommu core supports new ops to invalidate the cache after the modifictions in stage-1 page table. So far, the cache invalidation data is vendor specific, the data_type (IOMMU_HWPT_DATA_VTD_S1) defined for the vendor specific HWPT allocation is reused in the cache invalidation path. User should provide the correct data_type that suit with the type used in HWPT allocation. IOMMU_HWPT_INVALIDATE iotcl returns an error in @out_driver_error_code. However Intel VT-d does not define error code so far, so it's not easy to pre-define it in iommufd neither. As a result, this field should just be ignored on VT-d platform. Complete code can be found in [2], corresponding QEMU could can be found in [3].

[PATCH v6 0/6] iommufd: Add nesting infrastructure (part 2/2)

by Yi Liu

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

[PATCH bpf-next v2 0/3] Annotate kfuncs in .BTF_ids section

by Daniel Xu

=== Description === This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 3's description. The accompanying pahole changes (still needs some cleanup) can be viewed here on this "frozen" branch [0]. [0]: https://github.com/danobi/pahole/tree/kfunc_btf-mailed === Changelog === Changes from v1: * Move WARN_ON() up a call level * Also return error when kfunc set is not properly tagged * Use BTF_KFUNCS_START/END instead of flags * Rename BTF_SET8_KFUNC to BTF_SET8_KFUNCS Daniel Xu (3): bpf: btf: Support flags for BTF_SET8 sets bpf: btf: Add BTF_KFUNCS_START/END macro pair bpf: treewide: Annotate BPF kfuncs in BTF drivers/hid/bpf/hid_bpf_dispatch.c | 8 +++---- fs/verity/measure.c | 4 ++-- include/linux/btf_ids.h | 21 +++++++++++++++---- kernel/bpf/btf.c | 4 ++++ kernel/bpf/cpumask.c | 4 ++-- kernel/bpf/helpers.c | 8 +++---- kernel/bpf/map_iter.c | 4 ++-- kernel/cgroup/rstat.c | 4 ++-- kernel/trace/bpf_trace.c | 8 +++---- net/bpf/test_run.c | 8 +++---- net/core/filter.c | 16 +++++++------- net/core/xdp.c | 4 ++-- net/ipv4/bpf_tcp_ca.c | 4 ++-- net/ipv4/fou_bpf.c | 4 ++-- net/ipv4/tcp_bbr.c | 4 ++-- net/ipv4/tcp_cubic.c | 4 ++-- net/ipv4/tcp_dctcp.c | 4 ++-- net/netfilter/nf_conntrack_bpf.c | 4 ++-- net/netfilter/nf_nat_bpf.c | 4 ++-- net/xfrm/xfrm_interface_bpf.c | 4 ++-- net/xfrm/xfrm_state_bpf.c | 4 ++-- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 8 +++---- 22 files changed, 77 insertions(+), 60 deletions(-) -- 2.42.1

[PATCH net-next] selftests: forwarding: Avoid failures to source net/lib.sh

The expression "source ../lib.sh" added to net/forwarding/lib.sh in commit 25ae948b4478 ("selftests/net: add lib.sh") does not work for tests outside net/forwarding which source net/forwarding/lib.sh (1). It also does not work in some cases where only a subset of tests are exported (2). Avoid the problems mentioned above by replacing the faulty expression with a copy of the content from net/lib.sh which is used by files under net/forwarding. A more thorough solution which avoids duplicating content between net/lib.sh and net/forwarding/lib.sh has been posted here: https://lore.kernel.org/netdev/20231222135836.992841-1-bpoirier@nvidia.com/ The approach in the current patch is a stopgap solution to avoid submitting large changes at the eleventh hour of this development cycle. Example of problem 1) tools/testing/selftests/drivers/net/bonding$ ./dev_addr_lists.sh ./net_forwarding_lib.sh: line 41: ../lib.sh: No such file or directory TEST: bonding cleanup mode active-backup [ OK ] TEST: bonding cleanup mode 802.3ad [ OK ] TEST: bonding LACPDU multicast address to slave (from bond down) [ OK ] TEST: bonding LACPDU multicast address to slave (from bond up) [ OK ] An error message is printed but since the test does not use functions from net/lib.sh, the test results are not affected. Example of problem 2) tools/testing/selftests$ make install TARGETS="net/forwarding" tools/testing/selftests$ cd kselftest_install/net/forwarding/ tools/testing/selftests/kselftest_install/net/forwarding$ ./pedit_ip.sh veth{0..3} lib.sh: line 41: ../lib.sh: No such file or directory TEST: ping [ OK ] TEST: ping6 [ OK ] ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got .

Wdyt? _6_offset_to_skb_data is for sure not redundant. I don't test a partial fill from the most significant bits in my patch 13. u16_offset_to_skb_data is somewhat similar to fill_32bit_after_spill_64bit, but they aren't exactly the same: the former spills (u32)20 and fills (u16)20 (the same value), while my test spills (u64)0xXXXXXXXX00000000 and fills (u32)0 (the most significant bits are stripped). Maybe u16_offset_to_skb_data is redundant, but more coverage is better than less coverage, isn't it? > > diff --git a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > index 809a09732168..de03e72e07a9 100644 > > --- a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > +++ b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > @@ -217,7 +217,7 @@ __naked void uninit_u32_from_the_stack(void) > > > > SEC("tc") > > __description("Spill a u32 const scalar.

[PATCH net-next v3 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce the parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Removed some unnecessary HBH conditionals by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added selftests for IPv6 packets with extension headers in GRO Richard v2 -> v3: - Removed previously added IPv6 extension header length constant and using sizeof(*opth) instead. - Removed unnecessary conditional in gro selftest framework - v2: https://lore.kernel.org/netdev/127b8199-1cd4-42d7-9b2b-875abaad93fe@gmail.c… v1 -> v2: - Added a minimum IPv6 extension header length constant to make code self documenting. - Added new selftest which checks that packets with different extension header payloads do not coalesce. - Added more info in the second commit message regarding the code changes. - v1: https://lore.kernel.org/netdev/f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.c… Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce tests net/ipv6/exthdrs_offload.c | 11 ++++ net/ipv6/ip6_offload.c | 76 +++++++++++++++++-------- tools/testing/selftests/net/gro.c | 93 +++++++++++++++++++++++++++++-- 3 files changed, 150 insertions(+), 30 deletions(-) -- 2.36.1

[PATCH v4 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH bpf-next 0/2] Annotate kfuncs in .BTF_ids section

by Daniel Xu

This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 2's description.

[PATCHv3 net-next 3/3] selftest/ptp: extend test to include ptp_gettimex64any()

by Mahesh Bandewar

Update testptp.c to exercise the new ptp method gettimex64any(). When only -x option is given the PTP_SYS_OFFSET_EXTENDED or gettimex64() method is exercised while presence of -x with -y will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method. -y option is to choose the timebase from available options of real, mono, or raw.

[RFC PATCH v3 0/3] Add test to verify probe of devices from discoverable busses

by Nícolas F. R. A. Prado

Hi, for this v3 I changed the approach for identifying devices in a stable way from the match fields back to the hardware topology (used in v1). The match fields were proposed as a way to avoid the possible issue of PCI topology being reconfigured, but that wasn't observed on any real system so far. However using match fields does allow for a real issue if an external device similar to an internal one is connected to the system, which results in a change of the match count and therefore a test failure. So using the HW topology was chosen as the most reliable approach. The per-platform device description file now uses YAML following a suggestion from Chris Obbard, and the test script was re-written in python to handle the new YAML format. A second sample board file is also now included for an x86 platform, which contains an USB controller behind a PCI controller, which wasn't possible to describe in v1. Thanks, Nícolas v2: https://lore.kernel.org/all/20231127233558.868365-1-nfraprado@collabora.com v1: https://lore.kernel.org/all/20231024211818.365844-1-nfraprado@collabora.com Original cover letter: This is part of an effort to improve detection of regressions impacting device probe on all platforms. The recently merged DT kselftest [3] detects probe issues for all devices described statically in the DT. That leaves out devices discovered at run-time from discoverable busses. This is where this test comes in. All of the devices that are connected through discoverable busses (ie USB and PCI), and which are internal and therefore always present, can be described in a per-platform file so they can be checked for. The test will check that the device has been instantiated and bound to a driver. Patch 1 introduces the test. Patch 2 and 3 add the device definitions for the google,spherion machine (Acer Chromebook 514) and XPS 13 as examples.

[PATCH] kunit: Protect string comparisons against NULL

by Richard Fitzgerald

Add NULL checks to KUNIT_BINARY_STR_ASSERTION() so that it will fail cleanly if either pointer is NULL, instead of causing a NULL pointer dereference in the strcmp(). A test failure could be that a string is unexpectedly NULL. This could be trapped by KUNIT_ASSERT_NOT_NULL() but that would terminate the test at that point. It's preferable that the KUNIT_EXPECT_STR*() macros can handle NULL pointers as a failure.

[PATCH v2 net-next] selftests/net: change shebang to bash to support "source"

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2]) have a /bin/sh shebang which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to fix the following issues when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 v1 -> v2: - Fix pmtu.sh which has the same issue as unicast_extensions.sh, suggested by Hangbin - Change the style of the "source" line to be consistent with other tests, suggested by Hangbin Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Link: https://lore.kernel.org/all/20231219094856.1740079-1-liuhangbin@gmail.com/ [2] Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/pmtu.sh | 4 ++-- tools/testing/selftests/net/unicast_extensions.sh | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/pmtu.sh b/tools/testing/selftests/net/pmtu.sh index 175d3d1d773b..f10879788f61 100755 --- a/tools/testing/selftests/net/pmtu.sh +++ b/tools/testing/selftests/net/pmtu.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # Check that route PMTU values match expectations, and that initial device MTU @@ -198,7 +198,7 @@ # - pmtu_ipv6_route_change # Same as above but with IPv6 -source ./lib.sh +source lib.sh PAUSE_ON_FAIL=no VERBOSE=0 diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..f52aa5f7da52 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project @@ -28,7 +28,7 @@ # These tests provide an easy way to flip the expected result of any # of these behaviors for testing kernel patches that change them. -source ./lib.sh +source lib.sh # nettest can be run from PATH or from same directory as this selftest if ! which nettest >/dev/null; then base-commit: cd4d7263d58ab98fd4dee876776e4da6c328faa3 -- 2.34.1

[PATCH v10 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks. [1] https://lore.kernel.org/linux-iommu/20231026044216.64964-1-yi.l.liu@intel.c… - merged [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1 Change log: v10: - Minor tweak to patch 07 (Kevin) - Rebase on top of 6.7-rc8 v9: https://lore.kernel.org/linux-iommu/20231228150629.13149-1-yi.l.liu@intel.c… - Add a test case which sets both IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in flags, and expect to succeed and see an 'error'. (Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6. Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it.

[PATCH bpf-next 0/2] bpf: add csum/ip_summed fields to __sk_buff

by Menglong Dong

For now, we have to call some helpers when we need to update the csum, such as bpf_l4_csum_replace, bpf_l3_csum_replace, etc. These helpers are not inlined, which causes poor performance. In fact, we can define our own csum update functions in BPF program instead of bpf_l3_csum_replace, which is totally inlined and efficient. However, we can't do this for bpf_l4_csum_replace for now, as we can't update skb->csum, which can cause skb->csum invalid in the rx path with CHECKSUM_COMPLETE mode. What's more, we can't use the direct data access and have to use skb_store_bytes() with the BPF_F_RECOMPUTE_CSUM flag in some case, such as modifing the vni in the vxlan header and the underlay udp header has no checksum. In the first patch, we make skb->csum readable and writable, and we make skb->ip_summed readable. For now, for tc only. With these 2 fields, we don't need to call bpf helpers for csum update any more. In the second patch, we add some testcases for the read/write testing for skb->csum and skb->ip_summed. If this series is acceptable, we can define the inlined functions for csum update in libbpf in the next step.

[PATCH v2 1/1] userfaultfd: fix move_pages_pte() splitting folio under RCU read lock

by Suren Baghdasaryan

While testing the split PMD path with lockdep enabled I've got an "Invalid wait context" error caused by split_huge_page_to_list() trying to lock anon_vma->rwsem while inside RCU read section. The issues is due to move_pages_pte() calling split_folio() under RCU read lock. Fix this by unmapping the PTEs and exiting RCU read section before splitting the folio and then retrying. The same retry pattern is used when locking the folio or anon_vma in this function. After splitting the large folio we unlock and release it because after the split the old folio might not be the one that contains the src_addr.

[PATCH v8 00/24] security: Move IMA and EVM to the LSM infrastructure

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> IMA and EVM are not effectively LSMs, especially due to the fact that in the past they could not provide a security blob while there is another LSM active. That changed in the recent years, the LSM stacking feature now makes it possible to stack together multiple LSMs, and allows them to provide a security blob for most kernel objects. While the LSM stacking feature has some limitations being worked out, it is already suitable to make IMA and EVM as LSMs. The main purpose of this patch set is to remove IMA and EVM function calls, hardcoded in the LSM infrastructure and other places in the kernel, and to register them as LSM hook implementations, so that those functions are called by the LSM infrastructure like other regular LSMs. This patch set introduces two new LSMs 'ima' and 'evm', so that functions can be registered to their respective LSM, and removes the 'integrity' LSM. integrity_kernel_module_request() was moved to IMA, since it was related to appraisal. integrity_inode_free() was replaced with ima_inode_free_security() (EVM does not need to free memory). In order to make 'ima' and 'evm' independent LSMs, it was necessary to split integrity metadata used by both IMA and EVM, and to let them manage their own. The special case of the IMA_NEW_FILE flag, managed by IMA and used by EVM, was handled by introducing a new flag in EVM, EVM_NEW_FILE, managed by two additional LSM hooks, evm_post_path_mknod() and evm_file_free(), equivalent to their counterparts ima_post_path_mknod() and ima_file_free(). In addition to splitting metadata, it was decided to embed the full structure into the inode security blob, rather than using a cache of objects and allocating them on demand. This opens for new possibilities, such as improving locking in IMA. Another follow-up change was removing the iint parameter from evm_verifyxattr(), that IMA used to pass integrity metadata to EVM. After splitting metadata, and aligning EVM_NEW_FILE with IMA_NEW_FILE, this parameter was not necessary anymore. The last part was to ensure that the order of IMA and EVM functions is respected after they become LSMs. Since the order of lsm_info structures in the .lsm_info.init section depends on the order object files containing those structures are passed to the linker of the kernel image, and since IMA is before EVM in the Makefile, that is sufficient to assert that IMA functions are executed before EVM ones. The patch set is organized as follows. Patches 1-9 make IMA and EVM functions suitable to be registered to the LSM infrastructure, by aligning function parameters. Patches 10-18 add new LSM hooks in the same places where IMA and EVM functions are called, if there is no LSM hook already. Patches 19-21 introduce the new standalone LSMs 'ima' and 'evm', and move hardcoded calls to IMA, EVM and integrity functions to those LSMs. Patches 22-23 remove the dependency on the 'integrity' LSM by splitting integrity metadata, so that the 'ima' and 'evm' LSMs can use their own. They also duplicate iint_lockdep_annotate() in ima_main.c, since the mutex field was moved from integrity_iint_cache to ima_iint_cache. Patch 24 finally removes the 'integrity' LSM, since 'ima' and 'evm' are now self-contained and independent. The patch set applies on top of lsm/dev, commit 80b4ff1d2c9b ("selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test"). The linux-integrity/next-integrity-testing at commit f17167bea279 ("ima: Remove EXPERIMENTAL from Kconfig") was merged. Changelog: v7: - Use return instead of goto in __vfs_removexattr_locked() (suggested by Casey) - Clarify in security/integrity/Makefile that the order of 'ima' and 'evm' LSMs depends on the order in which IMA and EVM are compiled - Move integrity_iint_cache flags to ima.h and evm.h in security/ and duplicate IMA_NEW_FILE to EVM_NEW_FILE - Rename evm_inode_get_iint() to evm_iint_inode() and ima_inode_get_iint() to ima_iint_inode(), check if inode->i_security is NULL, and just return the pointer from the inode security blob - Restore the non-NULL checks after ima_iint_inode() and evm_iint_inode() (suggested by Casey) - Introduce evm_file_free() to clear EVM_NEW_FILE - Remove comment about LSM_ORDER_LAST not guaranteeing the order of 'ima' and 'evm' LSMs - Lock iint->mutex before reading IMA_COLLECTED flag in __ima_inode_hash() and restored ima_policy_flag check - Remove patch about the hardcoded ordering of 'ima' and 'evm' LSMs in security.c - Add missing ima_inode_free_security() to free iint->ima_hash - Add the cases for LSM_ID_IMA and LSM_ID_EVM in lsm_list_modules_test.c - Mention about the change in IMA and EVM post functions for private inodes v6: - See v7 v5: - Rename security_file_pre_free() to security_file_release() and the LSM hook file_pre_free_security to file_release (suggested by Paul) - Move integrity_kernel_module_request() to ima_main.c (renamed to ima_kernel_module_request()) - Split the integrity_iint_cache structure into ima_iint_cache and evm_iint_cache, so that IMA and EVM can use disjoint metadata and reserve space with the LSM infrastructure - Reserve space for the entire ima_iint_cache and evm_iint_cache structures, not just the pointer (suggested by Paul) - Introduce ima_inode_get_iint() and evm_inode_get_iint() to retrieve respectively the ima_iint_cache and evm_iint_cache structure from the security blob - Remove the various non-NULL checks for the ima_iint_cache and evm_iint_cache structures, since the LSM infrastructure ensure that they always exist - Remove the iint parameter from evm_verifyxattr() since IMA and EVM use disjoint integrity metaddata - Introduce the evm_post_path_mknod() to set the IMA_NEW_FILE flag - Register the inode_alloc_security LSM hook in IMA and EVM to initialize the respective integrity metadata structures - Remove the 'integrity' LSM completely and instead make 'ima' and 'evm' proper standalone LSMs - Add the inode parameter to ima_get_verity_digest(), since the inode field is not present in ima_iint_cache - Move iint_lockdep_annotate() to ima_main.c (renamed to ima_iint_lockdep_annotate()) - Remove ima_get_lsm_id() and evm_get_lsm_id(), since IMA and EVM directly register the needed LSM hooks - Enforce 'ima' and 'evm' LSM ordering at LSM infrastructure level v4: - Improve short and long description of security_inode_post_create_tmpfile(), security_inode_post_set_acl(), security_inode_post_remove_acl() and security_file_post_open() (suggested by Mimi) - Improve commit message of 'ima: Move to LSM infrastructure' (suggested by Mimi) v3: - Drop 'ima: Align ima_post_path_mknod() definition with LSM infrastructure' and 'ima: Align ima_post_create_tmpfile() definition with LSM infrastructure', define the new LSM hooks with the same IMA parameters instead (suggested by Mimi) - Do IS_PRIVATE() check in security_path_post_mknod() and security_inode_post_create_tmpfile() on the new inode rather than the parent directory (in the post method it is available) - Don't export ima_file_check() (suggested by Stefan) - Remove redundant check of file mode in ima_post_path_mknod() (suggested by Mimi) - Mention that ima_post_path_mknod() is now conditionally invoked when CONFIG_SECURITY_PATH=y (suggested by Mimi) - Mention when a LSM hook will be introduced in the IMA/EVM alignment patches (suggested by Mimi) - Simplify the commit messages when introducing a new LSM hook - Still keep the 'extern' in the function declaration, until the declaration is removed (suggested by Mimi) - Improve documentation of security_file_pre_free() - Register 'ima' and 'evm' as standalone LSMs (suggested by Paul) - Initialize the 'ima' and 'evm' LSMs from 'integrity', to keep the original ordering of IMA and EVM functions as when they were hardcoded - Return the IMA and EVM LSM IDs to 'integrity' for registration of the integrity-specific hooks - Reserve an xattr slot from the 'evm' LSM instead of 'integrity' - Pass the LSM ID to init_ima_appraise_lsm() v2: - Add description for newly introduced LSM hooks (suggested by Casey) - Clarify in the description of security_file_pre_free() that actions can be performed while the file is still open v1: - Drop 'evm: Complete description of evm_inode_setattr()', 'fs: Fix description of vfs_tmpfile()' and 'security: Introduce LSM_ORDER_LAST', they were sent separately (suggested by Christian Brauner) - Replace dentry with file descriptor parameter for security_inode_post_create_tmpfile() - Introduce mode_stripped and pass it as mode argument to security_path_mknod() and security_path_post_mknod() - Use goto in do_mknodat() and __vfs_removexattr_locked() (suggested by Mimi) - Replace __lsm_ro_after_init with __ro_after_init - Modify short description of security_inode_post_create_tmpfile() and security_inode_post_set_acl() (suggested by Stefan) - Move security_inode_post_setattr() just after security_inode_setattr() (suggested by Mimi) - Modify short description of security_key_post_create_or_update() (suggested by Mimi) - Add back exported functions ima_file_check() and evm_inode_init_security() respectively to ima.h and evm.h (reported by kernel robot) -

[PATCH net-next 0/4] mptcp: add CurrEstab MIB counter

by Matthieu Baerts

This MIB counter is similar to the one of TCP -- CurrEstab -- available in /proc/net/snmp. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. Patch 1 prepares its support by adding new helper functions: - MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to decrement a counter. - mptcp_set_state(): similar to tcp_set_state(), to change the state of an MPTCP socket, and to inc/decrement the new counter when needed. Patch 2 uses mptcp_set_state() instead of directly calling inet_sk_state_store() to change the state of MPTCP sockets. Patch 3 and 4 validate the new feature in MPTCP "join" and "diag" selftests.

[PATCH v9 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

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

(Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6.

The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy().

[PATCH net-next] selftests/net: change the shebang of unicast_extensions.sh to bash

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. The shebang of unicast_extensions.sh is /bin/sh which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to suppress the following errors when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Fixes: 0f4765d0b48d ("selftests/net: convert unicast_extensions.sh to run it in unique namespace") Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/unicast_extensions.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..2766990c2b78 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project -- 2.34.1

Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy(). Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (4): iommu: Add cache_invalidate_user op iommu/vt-d: Allow qi_submit_sync() to return the QI faults iommu/vt-d: Convert pasid based cache invalidation to return QI fault iommu/vt-d: Add iotlb flush for nested domain Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (1): iommufd: Add IOMMU_HWPT_INVALIDATE drivers/iommu/intel/dmar.c | 36 ++-- drivers/iommu/intel/iommu.c | 12 +- drivers/iommu/intel/iommu.h | 8 +- drivers/iommu/intel/irq_remapping.c | 2 +- drivers/iommu/intel/nested.c | 116 ++++++++++++ drivers/iommu/intel/pasid.c | 14 +- drivers/iommu/intel/svm.c | 14 +- drivers/iommu/iommufd/hw_pagetable.c | 36 ++++ drivers/iommu/iommufd/iommufd_private.h | 10 ++ drivers/iommu/iommufd/iommufd_test.h | 39 ++++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 93 ++++++++++ include/linux/iommu.h | 101 +++++++++++ include/uapi/linux/iommufd.h | 100 +++++++++++ tools/testing/selftests/iommu/iommufd.c | 170 ++++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 57 ++++++ 16 files changed, 773 insertions(+), 38 deletions(-) -- 2.34.1

[PATCH net-next 0/4] mptcp: cleanup and support more ephemeral ports sockopts

by Matthieu Baerts

Patch 1 is a cleanup one: mptcp_is_tcpsk() helper was modifying sock_ops in some cases which is unexpected with that name. Patch 2 to 4 add support for two socket options: IP_LOCAL_PORT_RANGE and IP_BIND_ADDRESS_NO_PORT. The first one is a preparation patch, the second one adds the support while the last one modifies an existing selftest to validate the new features.

[PATCH bpf-next 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) Eduard Zingerman (4): bpf: make infinite loop detection in is_state_visited() exact selftests/bpf: check if imprecise stack spills confuse infinite loop detection bpf: Optimize state pruning for spilled scalars selftests/bpf: states pruning checks for scalar vs STACK_{MISC,ZERO} Maxim Mikityanskiy (11): selftests/bpf: Fix the u64_offset_to_skb_data test bpf: Make bpf_for_each_spilled_reg consider narrow spills selftests/bpf: Add a test case for 32-bit spill tracking bpf: Add the assign_scalar_id_before_mov function bpf: Add the get_reg_width function bpf: Assign ID to scalars on spill selftests/bpf: Test assigning ID to scalars on spill bpf: Track spilled unbounded scalars selftests/bpf: Test tracking spilled unbounded scalars bpf: Preserve boundaries and track scalars on narrowing fill selftests/bpf: Add test cases for narrowing fill include/linux/bpf_verifier.h | 2 +- kernel/bpf/verifier.c | 160 +++++- .../bpf/progs/verifier_direct_packet_access.c | 2 +- .../selftests/bpf/progs/verifier_loops1.c | 24 + .../selftests/bpf/progs/verifier_spill_fill.c | 529 +++++++++++++++++- .../testing/selftests/bpf/verifier/precise.c | 6 +- 6 files changed, 677 insertions(+), 46 deletions(-) -- 2.42.1

[PATCH] kunit: Fix some comments which were mistakenly kerneldoc

by David Gow

The KUnit device helpers are documented with kerneldoc in their header file, but also have short comments over their implementation. These were mistakenly formatted as kerneldoc comments, even though they're not valid kerneldoc. It shouldn't cause any serious problems -- this file isn't included in the docs -- but it could be confusing, and causes warnings. Remove the extra '*' so that these aren't treated as kerneldoc. Fixes: d03c720e03bd ("kunit: Add APIs for managing devices") Reported-by: kernel test robot <lkp(a)intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202312181920.H4EPAH20-lkp@intel.com/ Signed-off-by: David Gow <davidgow(a)google.com> --- lib/kunit/device.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/lib/kunit/device.c b/lib/kunit/device.c index 1db4305b615a..f5371287b375 100644 --- a/lib/kunit/device.c +++ b/lib/kunit/device.c @@ -60,7 +60,7 @@ static void kunit_device_release(struct device *d) kfree(to_kunit_device(d)); } -/** +/* * Create and register a KUnit-managed struct device_driver on the kunit_bus. * Returns an error pointer on failure. */ @@ -124,7 +124,7 @@ static struct kunit_device *kunit_device_register_internal(struct kunit *test, return kunit_dev; } -/** +/* * Create and register a new KUnit-managed device, using the user-supplied device_driver. * On failure, returns an error pointer. */ @@ -141,7 +141,7 @@ struct device *kunit_device_register_with_driver(struct kunit *test, } EXPORT_SYMBOL_GPL(kunit_device_register_with_driver); -/** +/* * Create and register a new KUnit-managed device, including a matching device_driver. * On failure, returns an error pointer. */ -- 2.43.0.472.g3155946c3a-goog

[PATCH net-next] selftest/tcp-ao: Rectify out-of-tree build

by Dmitry Safonov

Trivial fix for out-of-tree build that I wasn't testing previously: 1. Create a directory for library object files, fixes: > gcc lib/kconfig.c -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -I ../../../../../usr/include/ -iquote /tmp/kselftest/kselftest/net/tcp_ao/lib -I ../../../../include/ -o /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o -c > Assembler messages: > Fatal error: can't create /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o: No such file or directory > make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1 2.

[PATCH v4] tracing/selftests: Add ownership modification tests for eventfs

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership. It does the same for instances that change the ownership of he instance directory. Note, because the uid is not reset by a remount, it is tested for every file by switching it to a new owner and then back again.

[PATCH RFC v2 00/22] KVM: arm64: Implement support for SME in non-protected guests

by Mark Brown

This series implements support for SME use in non-protected KVM guests. Much of this is very similar to SVE, the main additional challenge that SME presents is that it introduces two new controls which change the registers seen by guests: - PSTATE.ZA enables the ZA matrix register and, if SME2 is supported, the ZT0 LUT register. - PSTATE.SM enables streaming mode, a new floating point mode which uses the SVE register set with a separately configured vector length. In streaming mode implementation of the FFR register is optional. It is also permitted to build systems which support SME without SVE, in this case when not in streaming mode no SVE registers or instructions are available. Further, there is no requirement that there be any overlap in the set of vector lengths supported by SVE and SME in a system, this is expected to be a common situation in practical systems. Since there is a new vector length to configure we introduce a new feature parallel to the existing SVE one with a new pseudo register for the streaming mode vector length. Due to the overlap with SVE caused by streaming mode rather than finalising SME as a separate feature we use the existing SVE finalisation to also finalise SME, a new define KVM_ARM_VCPU_VEC is provided to help make user code clearer. Finalising SVE and SME separately would introduce complication with register access since finalising SVE makes the SVE regsiters writeable by userspace and doing multiple finalisations results in an error being reported. Dealing with a state where the SVE registers are writeable due to one of SVE or SME being finalised but may have their VL changed by the other being finalised seems like needless complexity with minimal practical utility, it seems clearer to just express directly that only one finalisation can be done in the ABI. We represent the streaming mode registers to userspace by always using the existing SVE registers to access the floating point state, using the larger of the SME and (if enabled for the guest) SVE vector lengths. There are a large number of subfeatures for SME, most of which only offer additional instructions but some of which (SME2 and FA64) add architectural state. The expectation is that these will be configured via the ID registers but since the mechanism for doing this is still unclear the current code enables SME2 and FA64 for the guest if the host supports them regardless of what the ID registers say. Since we do not yet have support for SVE in protected guests and SME is very reliant on SVE this series does not implement support for SME in protected guests. This will be added separately once SVE support is merged into mainline (or along with merging that), there is code for protected guests using SVE in the Android tree. The new KVM_ARM_VCPU_VEC feature and ZA and ZT0 registers have not been added to the get-reg-list selftest, the idea of supporting additional features there without restructuring the program to generate all possible feature combinations has been rejected. I will post a separate series which does that restructuring. I am seeing some test failures currently which I've not got to the bottom of, at this point I'm reasonably sure these are preexisting issues in the kernel which are more apparent in a guest.

[PATCH v2 1/2] kunit: Allow passing function pointer to kunit_activate_static_stub()

by Richard Fitzgerald

Swap the arguments to typecheck_fn() in kunit_activate_static_stub() so that real_fn_addr can be either the function itself or a pointer to that function. This is useful to simplify redirecting static functions in a module. Having to pass the actual function meant that it must be exported from the module. Either making the 'static' and EXPORT_SYMBOL*() conditional (which makes the code messy), or change it to always exported (which increases the export namespace and prevents the compiler inlining a trivial stub function in non-test builds). With the original definition of kunit_activate_static_stub() the address of real_fn_addr was passed to typecheck_fn() as the type to be passed. This meant that if real_fn_addr was a pointer-to-function it would resolve to a ** instead of a *, giving an error like this: error: initialization of ‘int (**)(int)’ from incompatible pointer type ‘int (*)(int)’ [-Werror=incompatible-pointer-types] kunit_activate_static_stub(test, add_one_fn_ptr, subtract_one); | ^~~~~~~~~~~~ ./include/linux/typecheck.h:21:25: note: in definition of macro ‘typecheck_fn’ 21 | ({ typeof(type) __tmp = function; \ Swapping the arguments to typecheck_fn makes it take the type of a pointer to the replacement function. Either a function or a pointer to function can be assigned to that. For example: static int some_function(int x) { /* whatever */ } int (* some_function_ptr)(int) = some_function; static int replacement(int x) { /* whatever */ } Then: kunit_activate_static_stub(test, some_function, replacement); yields: typecheck_fn(typeof(&replacement), some_function); and: kunit_activate_static_stub(test, some_function_ptr, replacement); yields: typecheck_fn(typeof(&replacement), some_function_ptr); The two typecheck_fn() then resolve to: int (*__tmp)(int) = some_function; and int (*__tmp)(int) = some_function_ptr; Both of these are valid. In the first case the compiler inserts an implicit '&' to take the address of the supplied function, and in the second case the RHS is already a pointer to the same type.

[PATCH v2] tracing/selftests: Add ownership modification tests for eventfs

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership. It does the same for instances that change the ownership of he instance directory. Note, because the uid is not reset by a remount, it is tested for every file by switching it to a new owner and then back again.

[PATCH] selftests: uevent: use shared makefile library

by Antonio Terceiro

This makes the uevent selftests build not write to the source tree unconditionally, as that breaks out of tree builds when the source tree is read-only. It also avoids leaving a git repository in a dirty state after a build.

[PATCH 0/2] kselftest/seccomp: Convert to KTAP output

by Mark Brown

Currently the seccomp benchmark selftest produces non-standard output, meaning that while it makes a number of checks of the performance it observes this has to be parsed by humans. This means that automated systems running this suite of tests are almost certainly ignoring the results which isn't ideal for spotting problems. Let's rework things so that each check that the program does is reported as a test result to the framework.

selftests/livepatch fails on s390

by Alexander Gordeev

Hi all, The livepatch selftest somehow fails in -next on s390 due to what appears to me as 'comm' usage issue. E.g the removal of timestamp- less line "with link type OSD_10GIG." in the below output forces 'comm' to produce the correct result in check_result() function of tools/testing/selftests/livepatch/functions.sh script: [ 11.229256] qeth 0.0.bd02: qdio: OSA on SC 2624 using AI:1 QEBSM:0 PRI:1 TDD:1 SIGA: W [ 11.250189] systemd-journald[943]: Successfully sent stream file descriptor to service manager. [ 11.258763] qeth 0.0.bd00: Device is a OSD Express card (level: 0165) with link type OSD_10GIG. [ 11.259261] qeth 0.0.bd00: The device represents a Bridge Capable Port [ 11.262376] qeth 0.0.bd00: MAC address b2:96:9c:49:aa:e9 successfully registered [ 11.269654] qeth 0.0.bd00: MAC address 06:c6:b5:7d:ee:63 successfully registered By contrast, using the 'diff' instead works as a charm. But it was removed with commit 2f3f651f3756 ("selftests/livepatch: Use "comm" instead of "diff" for dmesg"). I am attaching the contents of "$expect" and "$result" script variables and the output of 'dmesg' before and after test run dmesg-saved.txt and dmesg.txt. Another 'dmesg' output dmesg-saved1.txt and dmesg1.txt also shows the same problem, which seems like something to do with sorting. The minimal reproducer attached is dmesg-saved1-rep.txt and dmesg1-rep.txt, that could be described as: --- dmesg-saved1-rep.txt 2023-12-17 21:08:14.171014218 +0100 +++ dmesg1-rep.txt 2023-12-17 21:06:52.221014218 +0100 @@ -1,3 +1,3 @@ -[ 98.820331] livepatch: 'test_klp_state2': starting patching transition [ 100.031067] livepatch: 'test_klp_state2': completing patching transition [ 284.224335] livepatch: kernel.ftrace_enabled = 1 +[ 284.232921] ===== TEST: basic shadow variable API ===== The culprit is the extra space in [ 98.820331] timestamp, that from the script point of view produces the output with two extra lines: [ 100.031067] livepatch: 'test_klp_state2': completing patching transition [ 284.224335] livepatch: kernel.ftrace_enabled = 1 [ 284.232921] ===== TEST: basic shadow variable API ===== If the line with [ 98.820331] timestamp removed or changed to e.g [ 100.031066] (aka 1 us less), then the result output is as expected: [ 284.232921] ===== TEST: basic shadow variable API ===== Thanks!

[PATCH v3 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. I'm sending the patches now so it can be discussed before Plumbers. Thanks in advance!

[PATCH v11 00/19] KVM: xen: update shared_info and vcpu_info handling

by Paul Durrant

From: Paul Durrant <pdurrant(a)amazon.com> This series has some small fixes from what was in version 10 [1]: * KVM: pfncache: allow a cache to be activated with a fixed (userspace) HVA This required a small fix to kvm_gpc_check() for an error that was introduced in version 8. * KVM: xen: separate initialization of shared_info cache and content This accidentally regressed a fix in commit 5d6d6a7d7e66a ("KVM: x86: Refine calculation of guest wall clock to use a single TSC read"). * KVM: xen: re-initialize shared_info if guest (32/64-bit) mode is set This mistakenly removed the initialization of shared_info from the code setting the KVM_XEN_ATTR_TYPE_SHARED_INFO attribute, which broke the self- tests. * KVM: xen: split up kvm_xen_set_evtchn_fast() This had a /32 and a /64 swapped in set_vcpu_info_evtchn_pending().

[PATCH bpf-next v5 0/4] bpf: support to track BPF_JNE

by Menglong Dong

For now, the reg bounds is not handled for BPF_JNE case, which can cause the failure of following case: /* The type of "a" is u32 */ if (a > 0 && a < 100) { /* the range of the register for a is [0, 99], not [1, 99], * and will cause the following error: * * invalid zero-sized read * * as a can be 0. */ bpf_skb_store_bytes(skb, xx, xx, a, 0); } In the code above, "a > 0" will be compiled to "if a == 0 goto xxx". In the TRUE branch, the dst_reg will be marked as known to 0. However, in the fallthrough(FALSE) branch, the dst_reg will not be handled, which makes the [min, max] for a is [0, 99], not [1, 99]. In the 1st patch, we reduce the range of the dst reg if the src reg is a const and is exactly the edge of the dst reg For BPF_JNE. In the 2nd patch, we remove reduplicated s32 casting in "crafted_cases". In the 3rd patch, we just activate the test case for this logic in range_cond(), which is committed by Andrii in the commit 8863238993e2 ("selftests/bpf: BPF register range bounds tester"). In the 4th patch, we convert the case above to a testcase and add it to verifier_bounds.c. Changes since v4: - add the 2nd patch - add "{U32, U32, {0, U32_MAX}, {U32_MAX, U32_MAX}}" that we missed in the 3rd patch - add some comments to the function that we add in the 4th patch - add reg_not_equal_const() in the 4th patch Changes since v3: - do some adjustment to the crafted cases that we added in the 2nd patch - add the 3rd patch Changes since v2: - fix a typo in the subject of the 1st patch - add some comments to the 1st patch, as Eduard advised - add some cases to the "crafted_cases" Changes since v1: - simplify the code in the 1st patch - introduce the 2nd patch for the testing Menglong Dong (4): bpf: make the verifier tracks the "not equal" for regs selftests/bpf: remove reduplicated s32 casting in "crafted_cases" selftests/bpf: activate the OP_NE logic in range_cond() selftests/bpf: add testcase to verifier_bounds.c for BPF_JNE kernel/bpf/verifier.c | 38 +++++++++++- .../selftests/bpf/prog_tests/reg_bounds.c | 27 +++++--- .../selftests/bpf/progs/verifier_bounds.c | 62 +++++++++++++++++++ 3 files changed, 116 insertions(+), 11 deletions(-) -- 2.39.2

[PATCH 1/2] kunit: Allow passing function pointer to kunit_activate_static_stub()

by Richard Fitzgerald

Swap the arguments to typecheck_fn() in kunit_activate_static_stub() so that real_fn_addr can be either the function itself or a pointer to that function. This is useful to simplify redirecting static functions in a module. Having to pass the actual function meant that it must be exported from the module. Either making the 'static' and EXPORT_SYMBOL*() conditional (which makes the code messy), or change it to always exported (which increases the export namespace and prevents the compiler inlining a trivial stub function in non-test builds). With the original definition of kunit_activate_static_stub() the address of real_fn_addr was passed to typecheck_fn() as the type to be passed. This meant that if real_fn_addr was a pointer-to-function it would resolve to a ** instead of a *, giving an error like this: error: initialization of ‘int (**)(int)’ from incompatible pointer type ‘int (*)(int)’ [-Werror=incompatible-pointer-types] kunit_activate_static_stub(test, add_one_fn_ptr, subtract_one); | ^~~~~~~~~~~~ ./include/linux/typecheck.h:21:25: note: in definition of macro ‘typecheck_fn’ 21 | ({ typeof(type) __tmp = function; \ Swapping the arguments to typecheck_fn makes it take the type of a pointer to the replacement function. Either a function or a pointer to function can be assigned to that.

[PATCH] selftests/seccomp: Try to fit runtime of benchmark into timeout

by Mark Brown

The seccomp benchmark runs five scenarios, one calibration run with no seccomp filters enabled then four further runs each adding a filter. The calibration run times itself for 15s and then each additional run executes for the same number of times. Currently the seccomp tests, including the benchmark, run with an extended 120s timeout but this is not sufficient to robustly run the tests on a lot of platforms. Sample timings from some recent runs: Platform Run 1 Run 2 Run 3 Run 4 --------- ----- ----- ----- ----- PowerEdge R200 16.6s 16.6s 31.6s 37.4s BBB (arm) 20.4s 20.4s 54.5s Synquacer (arm64) 20.7s 23.7s 40.3s The x86 runs from the PowerEdge are quite marginal and routinely fail, for the successful run reported here the timed portions of the run are at 117.2s leaving less than 3s of margin which is frequently breached. The added overhead of adding filters on the other platforms is such that there is no prospect of their runs fitting into the 120s timeout, especially on 32 bit arm where there is no BPF JIT. While we could lower the time we calibrate for I'm also already seeing the currently completing runs reporting issues with the per filter overheads not matching expectations: Let's instead raise the timeout to 180s which is only a 50% increase on the current timeout which is itself not *too* large given that there's only two tests in this suite.

Should I add BPF kfuncs for userspace apps? And how?

by Akihiko Odaki

Hi, It is said eBPF is a safe way to extend kernels and that is very attarctive, but we need to use kfuncs to add new usage of eBPF and kfuncs are said as unstable as EXPORT_SYMBOL_GPL. So now I'd like to ask some questions: 1) Which should I choose, BPF kfuncs or ioctl, when adding a new feature for userspace apps? 2) How should I use BPF kfuncs from userspace apps if I add them? Here, a "userspace app" means something not like a system-wide daemon like systemd (particularly, I have QEMU in mind). I'll describe the context more below: --- I'm working on a new feature that aids virtio-net implementations using tuntap virtual network device. You can see [1] for details, but basically it's to extend BPF_PROG_TYPE_SOCKET_FILTER to report four more bytes. However, with long discussions we have confirmed extending BPF_PROG_TYPE_SOCKET_FILTER is not going to happen, and adding kfuncs is the way forward. So I decided how to add kfuncs to the kernel and how to use it. There are rich documentations for the kernel side, but I found little about the userspace. The best I could find is a systemd change proposal that is based on WIP kernel changes[2]. So now I'm wondering how I should use BPF kfuncs from userspace apps if I add them. In the systemd discussion, it is told that Linus said it's fine to use BPF kfuncs in a private infrastructure big companies own, or in systemd as those users know well about the system[3]. Indeed, those users should be able to make more assumptions on the kernel than "normal" userspace applications can. Returning to my proposal, I'm proposing a new feature to be used by QEMU or other VMM applications. QEMU is more like a normal userspace application, and usually does not make much assumptions on the kernel it runs on. For example, it's generally safe to run a Debian container including QEMU installed with apt on Fedora. BPF kfuncs may work even in such a situation thanks to CO-RE, but it sounds like *accidentally* creating UAPIs. Considering all above, how can I integrate BPF kfuncs to the application? If BPF kfuncs are like EXPORT_SYMBOL_GPL, the natural way to handle them is to think of BPF programs as some sort of kernel modules and incorporate logic that behaves like modprobe. More concretely, I can put eBPF binaries to a directory like: /usr/local/share/qemu/ebpf/$KERNEL_RELEASE Then, QEMU can uname() and get the path to the binary. It will give an error if it can't find the binary for the current kernel so that it won't create accidental UAPIs. The obvious downside of this is that it complicates packaging a lot; it requires packaging QEMU eBPF binaries each time a new kernel comes up. This complexity is centrally managed by modprobe for kernel modules, but apparently each application needs to take care of it for BPF programs. In conclusion, I see too much complexity to use BPF in a userspace application, which we didn't have to care for BPF_PROG_TYPE_SOCKET_FILTER. Isn't there a better way? Or shouldn't I use BPF in my case in the first place? Thanks, Akihiko Odaki [1] https://lore.kernel.org/all/20231015141644.260646-1-akihiko.odaki@daynix.co… [2] https://github.com/systemd/systemd/pull/29797 [3] https://github.com/systemd/systemd/pull/29797#discussion_r1384637939

[PATCH] kselftest/arm64: Don't probe the current VL for unsupported vector types

by Mark Brown

The vec-syscfg selftest verifies that setting the VL of the currently tested vector type does not disrupt the VL of the other vector type. To do this it records the current vector length for each type but neglects to guard this with a check for that vector type actually being supported. Add one, using a helper function which we also update all the other instances of this pattern.

[PATCH v1] selftests/mm: Log run_vmtests.sh results in TAP format

by Ryan Roberts

When running tests on a CI system (e.g. LAVA) it is useful to output test results in TAP format so that the CI can parse the fine-grained results to show regressions. Many of the mm selftest binaries already output using the TAP format. And the kselftests runner (run_kselftest.sh) also uses the format. CI systems such as LAVA can already handle nested TAP reports. However, with the mm selftests we have 3 levels of nesting (run_kselftest.sh -> run_vmtests.sh -> individual test binaries) and the middle level did not previously support TAP, which breaks the parser. Let's fix that by teaching run_vmtests.sh to output using the TAP format. Ideally this would be opt-in via a command line argument to avoid the possibility of breaking anyone's existing scripts that might scrape the output. However, it is not possible to pass arguments to tests invoked via run_kselftest.sh. So I've implemented an opt-out option (-n), which will revert to the existing output format. Future changes to this file should be aware of 2 new conventions: - output that is part of the TAP reporting is piped through tap_output - general output is piped through tap_prefix Signed-off-by: Ryan Roberts <ryan.roberts(a)arm.com> --- tools/testing/selftests/mm/run_vmtests.sh | 51 +++++++++++++++++------ 1 file changed, 39 insertions(+), 12 deletions(-) diff --git a/tools/testing/selftests/mm/run_vmtests.sh b/tools/testing/selftests/mm/run_vmtests.sh index 87f513f5cf91..246d53a5d7f2 100755 --- a/tools/testing/selftests/mm/run_vmtests.sh +++ b/tools/testing/selftests/mm/run_vmtests.sh @@ -5,6 +5,7 @@ # Kselftest framework requirement - SKIP code is 4. ksft_skip=4 +count_total=0 count_pass=0 count_fail=0 count_skip=0 @@ -17,6 +18,7 @@ usage: ${BASH_SOURCE[0]:-$0} [ options ] -a: run all tests, including extra ones -t: specify specific categories to tests to run -h: display this message + -n: disable TAP output The default behavior is to run required tests only.

[PATCH] selftest: kvm: kvm_page_table_test: change default guest memory down to 128MB

by Itaru Kitayama

kvm_page_table_test's current default guest memory is set to 1GB, however on a 4GB of system memory this setting causes an OOM event. While it is able to control the test program arguments using an environment variable, KSELFTEST_KVM_PAGE_TABLE_TEST_ARGS, it is not intuitively clear for a selftest users the above variable exists, change the default guest memory down to 128MB so that small systems can run this test without seeing an OOM. --- Signed-off-by: Itaru Kitayama <itaru.kitayama(a)linux.dev> --- tools/testing/selftests/kvm/kvm_page_table_test.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/kvm/kvm_page_table_test.c b/tools/testing/selftests/kvm/kvm_page_table_test.c index 69f26d80c821..3cef22642bcb 100644 --- a/tools/testing/selftests/kvm/kvm_page_table_test.c +++ b/tools/testing/selftests/kvm/kvm_page_table_test.c @@ -24,8 +24,8 @@ #define TEST_MEM_SLOT_INDEX 1 -/* Default size(1GB) of the memory for testing */ -#define DEFAULT_TEST_MEM_SIZE (1 << 30) +/* Default size(128MB) of the memory for testing */ +#define DEFAULT_TEST_MEM_SIZE (1 << 27) /* Default guest test virtual memory offset */ #define DEFAULT_GUEST_TEST_MEM 0xc0000000 --- base-commit: a39b6ac3781d46ba18193c9dbb2110f31e9bffe9 change-id: 20231217-selftest-dev-c769544c303d Best regards, -- Itaru Kitayama <itaru.kitayama(a)linux.dev>

Hi all, Here's v4 series to improve resctrl selftests with generalized test framework and rewritten CAT test. The series contains following improvements: - Excludes shareable bits from CAT test allocation to avoid interference - Replaces file "sink" with a volatile variable - Alters read pattern to defeat HW prefetcher optimizations - Rewrites CAT test to make the CAT test reliable and truly measure if CAT is working or not - Introduces generalized test framework making easier to add new tests - Lots of other cleanups & refactoring This series has been tested across a large number of systems from different generations. v4: - Reworded a few error prints - Changelog improvements - fprintf()'s error handling changed ksft_perror() -> ksft_print_msg() - Keep using ksft_*() instead of fprintf() in get_bit_mask() - Check against div-by-zero - Adjust one return type v3: - New patches to handle return errno, perror() and return value comments - Tweak changelogs - Moved error printout removal to other patch - Zero bit CBM returns error - Tweak comments - Make get_shareable_mask() static - Return directly without storing result into ret variable first - llc -> LLC - Altered changelog and removed "the whole time" wording because llc occu results are still unsigned long - Altered changelog's wording to not say "a volatile pointer" - Make min_diff_percent and MIN_DIFF_PERCENT_PER_BIT unsigned long - Add patch to restore CPU affinity after CAT test - Move uparams clear into init function - Add CPU vendor ID bitmask comment - Use test_resource_feature_check(test) in CMT - "feature" -> "resource" in function comment v2: - Postpone adding L2 CAT test as more investigations are necessary - Add patch to remove ctrlc_handler() from wrong place - Improvements to changelogs - Function comments improvements & comment cleanups - Move some parts of the changes into more logical patch - If checks: buf == NULL -> !buf - Variable naming: - p -> buf - cbm_mask_path -> cbm_path - Function naming: - get_cbm_mask() -> get_full_cbm() - cache_size() -> cache_portion_size() - Use PATH_MAX - Improved cache_portion_size() parameter names - int count -> unsigned int - Pass filename to measurement taking functions instead of resctrl_val_param - !lines ? : reversal - Removed bogus static from function local variable - Open perf fd only once, reset & enable in the innermost test loop - Add perf fd ioctl() error handling - Add patch to change compiler optimization prevention "sink" from file to volatile variable - Remove cpu_no and resource (the latter was added in v1) members from resctrl_val_param (pass uparams and test where those are needed) - Removed ARRAY_SIZE() macro - Add patch to rename "resource_id" to "domain_id" Ilpo Järvinen (29): selftests/resctrl: Convert perror() to ksft_perror() or ksft_print_msg() selftests/resctrl: Return -1 instead of errno on error selftests/resctrl: Don't use ctrlc_handler() outside signal handling selftests/resctrl: Change function comments to say < 0 on error selftests/resctrl: Split fill_buf to allow tests finer-grained control selftests/resctrl: Refactor fill_buf functions selftests/resctrl: Refactor get_cbm_mask() and rename to get_full_cbm() selftests/resctrl: Mark get_cache_size() cache_type const selftests/resctrl: Create cache_portion_size() helper selftests/resctrl: Exclude shareable bits from schemata in CAT test selftests/resctrl: Split measure_cache_vals() selftests/resctrl: Split show_cache_info() to test specific and generic parts selftests/resctrl: Remove unnecessary __u64 -> unsigned long conversion selftests/resctrl: Remove nested calls in perf event handling selftests/resctrl: Consolidate naming of perf event related things selftests/resctrl: Improve perf init selftests/resctrl: Convert perf related globals to locals selftests/resctrl: Move cat_val() to cat_test.c and rename to cat_test() selftests/resctrl: Open perf fd before start & add error handling selftests/resctrl: Replace file write with volatile variable selftests/resctrl: Read in less obvious order to defeat prefetch optimizations selftests/resctrl: Rewrite Cache Allocation Technology (CAT) test selftests/resctrl: Restore the CPU affinity after CAT test selftests/resctrl: Create struct for input parameters selftests/resctrl: Introduce generalized test framework selftests/resctrl: Pass write_schemata() resource instead of test name selftests/resctrl: Add helper to convert L2/3 to integer selftests/resctrl: Rename resource ID to domain ID selftests/resctrl: Get domain id from cache id tools/testing/selftests/resctrl/cache.c | 287 +++++---------- tools/testing/selftests/resctrl/cat_test.c | 337 +++++++++++------- tools/testing/selftests/resctrl/cmt_test.c | 80 +++-- tools/testing/selftests/resctrl/fill_buf.c | 132 ++++--- tools/testing/selftests/resctrl/mba_test.c | 30 +- tools/testing/selftests/resctrl/mbm_test.c | 32 +- tools/testing/selftests/resctrl/resctrl.h | 135 +++++-- .../testing/selftests/resctrl/resctrl_tests.c | 197 ++++------ tools/testing/selftests/resctrl/resctrl_val.c | 138 +++---- tools/testing/selftests/resctrl/resctrlfs.c | 321 +++++++++++------ 10 files changed, 945 insertions(+), 744 deletions(-) -- 2.30.2

[PATCH v4 0/5] kunit: Add helpers for creating test-managed devices

by davidgow＠google.com

KUnit tests often need to provide a struct device, and thus far have mostly been using root_device_register() or platform devices to create a 'fake device' for use with, e.g., code which uses device-managed resources. This has several disadvantages, including not being designed for test use, scattering files in sysfs, and requiring manual teardown on test exit, which may not always be possible in case of failure. Instead, introduce a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit -- i.e., they will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. This is a follow-up to a previous proposal here: https://lore.kernel.org/linux-kselftest/20230325043104.3761770-1-davidgow@g… (The kunit_defer() function in the first patch there has since been merged as the 'deferred actions' feature.) My intention is to take this whole series in via the kselftest/kunit branch, but I'm equally okay with splitting up the later patches which use this to go via the various subsystem trees in case there are merge conflicts. Cheers, -- David Signed-off-by: David Gow <davidgow(a)google.com> --- Changes in v4: - Update tags, fix a missing Signed-off-by. - Link to v3: https://lore.kernel.org/r/20231214-kunit_bus-v3-0-7e9a287d3048@google.com Changes in v3: - Port the DRM tests to these new helpers (Thanks, Maxime!) - Include the lib/kunit/device-impl.h file, which was missing from the previous revision. - Fix a use-after-free bug in kunit_device_driver_test, which resulted in memory corruption on some clang-built UML builds. - The 'test_state' is now allocated with kunit_kzalloc(), not on the stack, as the stack will be gone when cleanup occurs. - Link to v2: https://lore.kernel.org/r/20231208-kunit_bus-v2-0-e95905d9b325@google.com Changes in v2: - Simplify device/driver/bus matching, removing the no-longer-required kunit_bus_match function. (Thanks, Greg) - The return values are both more consistent (kunit_device_register now returns an explicit error pointer, rather than failing the test), and better documented. - Add some basic documentation to the implementations as well as the headers. The documentation in the headers is still more complete, and is now properly compiled into the HTML documentation (under dev-tools/kunit/api/resources.html). (Thanks, Matti) - Moved the internal-only kunit_bus_init() function to a private header, lib/kunit/device-impl.h to avoid polluting the public headers, and match other internal-only headers. (Thanks, Greg) - Alphabetise KUnit includes in other test modules. (Thanks, Amadeusz.) - Several code cleanups, particularly around error handling and allocation. (Thanks Greg, Maxime) - Several const-correctness and casting improvements. (Thanks, Greg) - Added a new test to verify KUnit cleanup triggers device cleanup. (Thanks, Maxime). - Improved the user-specified device test to verify that probe/remove hooks are called correctly.

[PATCH] selftests: secretmem: Floor the memory size to the multiple of page_size

by Muhammad Usama Anjum

The "locked-in-memory size" limit per process can be non-multiple of page_size. The mmap() fails if we try to allocate locked-in-memory with same size as the allowed limit if it isn't multiple of the page_size because mmap() rounds off the memory size to be allocated to next multiple of page_size. Fix this by flooring the length to be allocated with mmap() to the previous multiple of the page_size.

[PATCH v7 00/11] arm64: perf: Add support for event counting threshold

by James Clark

Changes since v6: * Remove inlines from arm_pmuv3.c * Use format attribute mechanism from SPE * Re-arrange attributes so that threshold comes last and can potentially be extended * Emit an error if the max threshold is exceeded rather than clamping * Convert all register fields to GENMASK Changes since v5: * Restructure the docs and add some more explanations * PMMIR.WIDTH -> PMMIR.THWIDTH in one comment * Don't write EVTYPER.TC if TH is 0. Doesn't have any functional effect but it might be a bit easier to understand the code. * Expand the format field #define names Changes since v4: * Rebase onto v6.7-rc1, it no longer depends on kvmarm/next * Remove change that moved ARMV8_PMU_EVTYPE_MASK to the asm files. This actually depended on those files being included in a certain order with arm_pmuv3.h to avoid circular includes. Now the definition is done programmatically in arm_pmuv3.c instead. Changes since v3: * Drop #include changes to KVM source files because since commit bc512d6a9b92 ("KVM: arm64: Make PMEVTYPER<n>_EL0.NSH RES0 if EL2 isn't advertised"), KVM doesn't use ARMV8_PMU_EVTYPE_MASK anymore Changes since v2: * Split threshold_control attribute into two, threshold_compare and threshold_count so that it's easier to use * Add some notes to the first commit message and the cover letter about the behavior in KVM * Update the docs commit with regards to the split attribute Changes since v1: * Fix build on aarch32 by disabling FEAT_PMUv3_TH and splitting event type mask between the platforms * Change armv8pmu_write_evtype() to take unsigned long instead of u64 so it isn't unnecessarily wide on aarch32 * Add UL suffix to aarch64 event type mask definition ---- FEAT_PMUv3_TH (Armv8.8) is a new feature that allows conditional counting of PMU events depending on how much the event increments on a single cycle. Two new config fields for perf_event_open have been added, and a PMU cap file for reading the max_threshold. See the second commit message and the docs in the last commit for more details. The feature is not currently supported on KVM guests, and PMMIR is set to read as zero, so it's not advertised as available. But it can be added at a later time. Writes to PMEVTYPER.TC and TH from guests are already RES0. The change has been validated on the Arm FVP model: # Zero values, works as expected (as before). $ perf stat -e dtlb_walk/threshold=0,threshold_compare=0/ -- true 5962 dtlb_walk/threshold=0,threshold_compare=0/ # Threshold >= 255 causes count to be 0 because dtlb_walk doesn't # increase by more than 1 per cycle. $ perf stat -e dtlb_walk/threshold=255,threshold_compare=2/ -- true 0 dtlb_walk/threshold=255,threshold_compare=2/ # Keeping comparison as >= but lowering the threshold to 1 makes the # count return. $ perf stat -e dtlb_walk/threshold=1,threshold_compare=2/ -- true 6329 dtlb_walk/threshold=1,threshold_compare=2/ James Clark (11): arm: perf: Remove inlines from arm_pmuv3.c arm: perf/kvm: Use GENMASK for ARMV8_PMU_PMCR_N arm: perf: Use GENMASK for PMMIR fields arm: perf: Convert remaining fields to use GENMASK arm64: perf: Include threshold control fields in PMEVTYPER mask arm: pmu: Share user ABI format mechanism with SPE perf/arm_dmc620: Remove duplicate format attribute #defines KVM: selftests: aarch64: Update tools copy of arm_pmuv3.h arm: pmu: Move error message and -EOPNOTSUPP to individual PMUs arm64: perf: Add support for event counting threshold Documentation: arm64: Document the PMU event counting threshold feature Documentation/arch/arm64/perf.rst | 72 +++++++ arch/arm/kernel/perf_event_v7.c | 6 +- arch/arm64/kvm/pmu-emul.c | 8 +- arch/arm64/kvm/sys_regs.c | 4 +- drivers/perf/apple_m1_cpu_pmu.c | 6 +- drivers/perf/arm_dmc620_pmu.c | 22 +-- drivers/perf/arm_pmu.c | 11 +- drivers/perf/arm_pmuv3.c | 175 ++++++++++++++---- drivers/perf/arm_spe_pmu.c | 22 --- include/linux/perf/arm_pmu.h | 22 +++ include/linux/perf/arm_pmuv3.h | 34 ++-- tools/include/perf/arm_pmuv3.h | 43 +++-- .../kvm/aarch64/vpmu_counter_access.c | 5 +- 13 files changed, 296 insertions(+), 134 deletions(-) -- 2.34.1

[PATCH bpf-next v6 0/5] Add bpf_xdp_get_xfrm_state() kfunc

by Daniel Xu

This patchset adds two kfunc helpers, bpf_xdp_get_xfrm_state() and bpf_xdp_xfrm_state_release() that wrap xfrm_state_lookup() and xfrm_state_put(). The intent is to support software RSS (via XDP) for the ongoing/upcoming ipsec pcpu work [0]. Recent experiments performed on (hopefully) reproducible AWS testbeds indicate that single tunnel pcpu ipsec can reach line rate on 100G ENA nics.

[PATCH bpf-next v5 0/9] Add bpf_xdp_get_xfrm_state() kfunc

by Daniel Xu

This patchset adds two kfunc helpers, bpf_xdp_get_xfrm_state() and bpf_xdp_xfrm_state_release() that wrap xfrm_state_lookup() and xfrm_state_put(). The intent is to support software RSS (via XDP) for the ongoing/upcoming ipsec pcpu work [0]. Recent experiments performed on (hopefully) reproducible AWS testbeds indicate that single tunnel pcpu ipsec can reach line rate on 100G ENA nics. Note this patchset only tests/shows generic xfrm_state access. The "secret sauce" (if you can really even call it that) involves accessing a soon-to-be-upstreamed pcpu_num field in xfrm_state.

[PATCH v2 0/5] KVM: selftests: aarch64: Introduce pmu_event_filter_test

by Shaoqin Huang

The test is inspired by the pmu_event_filter_test which implemented by x86. On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first move some pmu common code from vpmu_counter_access to lib/aarch64/vpmu.c and include/aarch64/vpmu.h, which can be used by pmu_event_filter_test. Then fix a bug related to the [enable|disable]_counter, and at last, implement the test itself. Changelog: ---------- v1->v2: - Improve the commit message. [Eric] - Fix the bug in [enable|disable]_counter. [Raghavendra & Marc] - Add the check if kvm has attr KVM_ARM_VCPU_PMU_V3_FILTER. - Add if host pmu support the test event throught pmceid0. - Split the test_invalid_filter() to another patch.

[PATCH v3 00/29] selftests/resctrl: CAT test improvements & generalized test framework

by Ilpo Järvinen

Hi all, Here's v3 series to improve resctrl selftests with generalized test framework and rewritten CAT test. As agreed, v3 does not include the group naming patch which will become part of Maciej's non-contiguous serie. The error handling cleanups (return errno, perror() & return value comment cleanups) and CPU affinity restore for CAT test add to the patch count. The series contains following improvements: - Excludes shareable bits from CAT test allocation to avoid interference - Replaces file "sink" with a volatile variable - Alters read pattern to defeat HW prefetcher optimizations - Rewrites CAT test to make the CAT test reliable and truly measure if CAT is working or not - Introduces generalized test framework making easier to add new tests - Lots of other cleanups & refactoring This serie have been tested across a large number of systems from different generations. v3: - New patches to handle return errno, perror() and return value comments - Tweak changelogs - Moved error printout removal to other patch - Zero bit CBM returns error - Tweak comments - Make get_shareable_mask() static - Return directly without storing result into ret variable first - llc -> LLC - Altered changelog and removed "the whole time" wording because llc occu results are still unsigned long - Altered changelog's wording to not say "a volatile pointer" - Make min_diff_percent and MIN_DIFF_PERCENT_PER_BIT unsigned long - Add patch to restore CPU affinity after CAT test - Move uparams clear into init function - Add CPU vendor ID bitmask comment - Use test_resource_feature_check(test) in CMT - "feature" -> "resource" in function comment v2: - Postpone adding L2 CAT test as more investigations are necessary - Add patch to remove ctrlc_handler() from wrong place - Improvements to changelogs - Function comments improvements & comment cleanups - Move some parts of the changes into more logical patch - If checks: buf == NULL -> !buf - Variable naming: - p -> buf - cbm_mask_path -> cbm_path - Function naming: - get_cbm_mask() -> get_full_cbm() - cache_size() -> cache_portion_size() - Use PATH_MAX - Improved cache_portion_size() parameter names - int count -> unsigned int - Pass filename to measurement taking functions instead of resctrl_val_param - !lines ? : reversal - Removed bogus static from function local variable - Open perf fd only once, reset & enable in the innermost test loop - Add perf fd ioctl() error handling - Add patch to change compiler optimization prevention "sink" from file to volatile variable - Remove cpu_no and resource (the latter was added in v1) members from resctrl_val_param (pass uparams and test where those are needed) - Removed ARRAY_SIZE() macro - Add patch to rename "resource_id" to "domain_id" Ilpo Järvinen (29): selftests/resctrl: Convert perror() to ksft_perror() or ksft_print_msg() selftests/resctrl: Return -1 instead of errno on error selftests/resctrl: Don't use ctrlc_handler() outside signal handling selftests/resctrl: Change function comments to say < 0 on error selftests/resctrl: Split fill_buf to allow tests finer-grained control selftests/resctrl: Refactor fill_buf functions selftests/resctrl: Refactor get_cbm_mask() and rename to get_full_cbm() selftests/resctrl: Mark get_cache_size() cache_type const selftests/resctrl: Create cache_portion_size() helper selftests/resctrl: Exclude shareable bits from schemata in CAT test selftests/resctrl: Split measure_cache_vals() selftests/resctrl: Split show_cache_info() to test specific and generic parts selftests/resctrl: Remove unnecessary __u64 -> unsigned long conversion selftests/resctrl: Remove nested calls in perf event handling selftests/resctrl: Consolidate naming of perf event related things selftests/resctrl: Improve perf init selftests/resctrl: Convert perf related globals to locals selftests/resctrl: Move cat_val() to cat_test.c and rename to cat_test() selftests/resctrl: Open perf fd before start & add error handling selftests/resctrl: Replace file write with volatile variable selftests/resctrl: Read in less obvious order to defeat prefetch optimizations selftests/resctrl: Rewrite Cache Allocation Technology (CAT) test selftests/resctrl: Restore the CPU affinity after CAT test selftests/resctrl: Create struct for input parameters selftests/resctrl: Introduce generalized test framework selftests/resctrl: Pass write_schemata() resource instead of test name selftests/resctrl: Add helper to convert L2/3 to integer selftests/resctrl: Rename resource ID to domain ID selftests/resctrl: Get domain id from cache id tools/testing/selftests/resctrl/cache.c | 287 +++++---------- tools/testing/selftests/resctrl/cat_test.c | 337 +++++++++++------- tools/testing/selftests/resctrl/cmt_test.c | 80 +++-- tools/testing/selftests/resctrl/fill_buf.c | 132 ++++--- tools/testing/selftests/resctrl/mba_test.c | 30 +- tools/testing/selftests/resctrl/mbm_test.c | 32 +- tools/testing/selftests/resctrl/resctrl.h | 126 +++++-- .../testing/selftests/resctrl/resctrl_tests.c | 197 ++++------ tools/testing/selftests/resctrl/resctrl_val.c | 138 +++---- tools/testing/selftests/resctrl/resctrlfs.c | 321 +++++++++++------ 10 files changed, 936 insertions(+), 744 deletions(-) -- 2.30.2

[PATCH v3 0/5] kunit: Add helpers for creating test-managed devices

by davidgow＠google.com

KUnit tests often need to provide a struct device, and thus far have mostly been using root_device_register() or platform devices to create a 'fake device' for use with, e.g., code which uses device-managed resources. This has several disadvantages, including not being designed for test use, scattering files in sysfs, and requiring manual teardown on test exit, which may not always be possible in case of failure. Instead, introduce a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit -- i.e., they will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. This is a follow-up to a previous proposal here: https://lore.kernel.org/linux-kselftest/20230325043104.3761770-1-davidgow@g… (The kunit_defer() function in the first patch there has since been merged as the 'deferred actions' feature.) My intention is to take this whole series in via the kselftest/kunit branch, but I'm equally okay with splitting up the later patches which use this to go via the various subsystem trees in case there are merge conflicts. Cheers, -- David Signed-off-by: David Gow <davidgow(a)google.com> --- Changes in v3: - Port the DRM tests to these new helpers (Thanks, Maxime!) - Include the lib/kunit/device-impl.h file, which was missing from the previous revision. - Fix a use-after-free bug in kunit_device_driver_test, which resulted in memory corruption on some clang-built UML builds. - The 'test_state' is now allocated with kunit_kzalloc(), not on the stack, as the stack will be gone when cleanup occurs. - Link to v2: https://lore.kernel.org/r/20231208-kunit_bus-v2-0-e95905d9b325@google.com Changes in v2: - Simplify device/driver/bus matching, removing the no-longer-required kunit_bus_match function. (Thanks, Greg) - The return values are both more consistent (kunit_device_register now returns an explicit error pointer, rather than failing the test), and better documented. - Add some basic documentation to the implementations as well as the headers. The documentation in the headers is still more complete, and is now properly compiled into the HTML documentation (under dev-tools/kunit/api/resources.html). (Thanks, Matti) - Moved the internal-only kunit_bus_init() function to a private header, lib/kunit/device-impl.h to avoid polluting the public headers, and match other internal-only headers. (Thanks, Greg) - Alphabetise KUnit includes in other test modules. (Thanks, Amadeusz.) - Several code cleanups, particularly around error handling and allocation. (Thanks Greg, Maxime) - Several const-correctness and casting improvements. (Thanks, Greg) - Added a new test to verify KUnit cleanup triggers device cleanup. (Thanks, Maxime). - Improved the user-specified device test to verify that probe/remove hooks are called correctly. (Thanks, Maxime). - The overflow test no-longer needlessly calls kunit_device_unregister(). - Several other minor cleanups and documentation improvements, which hopefully make this a bit clearer and more robust. - Link to v1: https://lore.kernel.org/r/20231205-kunit_bus-v1-0-635036d3bc13@google.com --- David Gow (4): kunit: Add APIs for managing devices fortify: test: Use kunit_device overflow: Replace fake root_device with kunit_device ASoC: topology: Replace fake root_device with kunit_device in tests Maxime Ripard (1): drm/tests: Switch to kunit devices Documentation/dev-tools/kunit/api/resource.rst | 9 ++ Documentation/dev-tools/kunit/usage.rst | 50 +++++++ drivers/gpu/drm/tests/drm_kunit_helpers.c | 66 +-------- include/kunit/device.h | 80 +++++++++++ lib/fortify_kunit.c | 5 +- lib/kunit/Makefile | 3 +- lib/kunit/device-impl.h | 17 +++ lib/kunit/device.c | 181 +++++++++++++++++++++++++ lib/kunit/kunit-test.c | 134 +++++++++++++++++- lib/kunit/test.c | 3 + lib/overflow_kunit.c | 5 +- sound/soc/soc-topology-test.c | 10 +- 12 files changed, 485 insertions(+), 78 deletions(-) --- base-commit: b285ba6f8cc1b2bfece0b4350fdb92c8780bc698 change-id: 20230718-kunit_bus-ab19c4ef48dc Best regards, -- David Gow <davidgow(a)google.com>

[PATCH v10 00/19] KVM: xen: update shared_info and vcpu_info handling

by Paul Durrant

From: Paul Durrant <pdurrant(a)amazon.com> There are four new patches in the series over what was in version 9 [1]: * KVM: xen: separate initialization of shared_info cache and content * KVM: xen: (re-)initialize shared_info if guest (32/64-bit) mode is set These deal with a missing re-initialization of shared_info if either the guest or VMM changes the 'long_mode' flag. This was discovred in testing when the guest wallclock reverted to the Unix epoch because the pvclock information in the shared_info page was not in the correct place, and so the guest read zeroes instead. * KVM: xen: don't block on pfncache locks in kvm_xen_set_evtchn_fast() * KVM: pfncache: check the need for invalidation under read lock first The first of these fixes a bug discovered when compiling the kernel with CONFIG_PROVE_RAW_LOCK_NESTING: kvm_xen_set_evtchn_fast() can be called from the callback of a HRTIMER_MODE_ABS_HARD timer and hence be executed in IRQ context. It should therefore not block on any lock. Thus two occurrences of a read_lock() are converted to a read_trylock() which kick the code down a slow-path if they fail. The second patch removes a 'false' contention on the pfncache lock that could result in taking that slow-path: the MMU notifier callback need only take a pfncache read lock; it only need take a write lock if a match is found. Apart from these new patches... * KVM: xen: split up kvm_xen_set_evtchn_fast() ... has been re-worked to (hopefully) improve readability and also validate the 'correct' vcpu_info structure depending on whether the guest is in long mode or not.

[PATCH v3 00/25] Permission Overlay Extension

by Joey Gouly

Hello everyone, This series implements the Permission Overlay Extension introduced in 2022 VMSA enhancements [1]. It is based on v6.7-rc2. Changes since v2[2]: # Added ptrace support and selftest # Add missing POR_EL0 initialisation in fork/clone # Rebase onto v6.7-rc2 # Add r-bs The Permission Overlay Extension allows to constrain permissions on memory regions. This can be used from userspace (EL0) without a system call or TLB invalidation. POE is used to implement the Memory Protection Keys [3] Linux syscall. The first few patches add the basic framework, then the PKEYS interface is implemented, and then the selftests are made to work on arm64. There was discussion about what the 'default' protection key value should be, I used disallow-all (apart from pkey 0), which matches what x86 does. I have tested the modified protection_keys test on x86_64, but not PPC. I haven't build tested the x86/ppc arch changes. Thanks, Joey [1] https://community.arm.com/arm-community-blogs/b/architectures-and-processor… [2] https://lore.kernel.org/linux-arm-kernel/20231027180850.1068089-1-joey.goul… [3] Documentation/core-api/protection-keys.rst Joey Gouly (25): arm64/sysreg: add system register POR_EL{0,1} arm64/sysreg: update CPACR_EL1 register arm64: cpufeature: add Permission Overlay Extension cpucap arm64: disable trapping of POR_EL0 to EL2 arm64: context switch POR_EL0 register KVM: arm64: Save/restore POE registers arm64: enable the Permission Overlay Extension for EL0 arm64: add POIndex defines arm64: define VM_PKEY_BIT* for arm64 arm64: mask out POIndex when modifying a PTE arm64: enable ARCH_HAS_PKEYS on arm64 arm64: handle PKEY/POE faults arm64: stop using generic mm_hooks.h arm64: implement PKEYS support arm64: add POE signal support arm64: enable PKEY support for CPUs with S1POE arm64: enable POE and PIE to coexist arm64/ptrace: add support for FEAT_POE kselftest/arm64: move get_header() selftests: mm: move fpregs printing selftests: mm: make protection_keys test work on arm64 kselftest/arm64: add HWCAP test for FEAT_S1POE kselftest/arm64: parse POE_MAGIC in a signal frame kselftest/arm64: Add test case for POR_EL0 signal frame records KVM: selftests: get-reg-list: add Permission Overlay registers Documentation/arch/arm64/elf_hwcaps.rst | 3 + arch/arm64/Kconfig | 18 +++ arch/arm64/include/asm/cpufeature.h | 6 + arch/arm64/include/asm/el2_setup.h | 10 +- arch/arm64/include/asm/hwcap.h | 1 + arch/arm64/include/asm/kvm_arm.h | 4 +- arch/arm64/include/asm/kvm_host.h | 4 + arch/arm64/include/asm/mman.h | 8 +- arch/arm64/include/asm/mmu.h | 2 + arch/arm64/include/asm/mmu_context.h | 51 ++++++- arch/arm64/include/asm/page.h | 10 ++ arch/arm64/include/asm/pgtable-hwdef.h | 10 ++ arch/arm64/include/asm/pgtable-prot.h | 8 +- arch/arm64/include/asm/pgtable.h | 26 +++- arch/arm64/include/asm/pkeys.h | 110 ++++++++++++++ arch/arm64/include/asm/por.h | 33 +++++ arch/arm64/include/asm/processor.h | 1 + arch/arm64/include/asm/sysreg.h | 16 ++ arch/arm64/include/asm/traps.h | 1 + arch/arm64/include/uapi/asm/hwcap.h | 1 + arch/arm64/include/uapi/asm/sigcontext.h | 7 + arch/arm64/kernel/cpufeature.c | 23 +++ arch/arm64/kernel/cpuinfo.c | 1 + arch/arm64/kernel/process.c | 22 +++ arch/arm64/kernel/ptrace.c | 46 ++++++ arch/arm64/kernel/signal.c | 51 +++++++ arch/arm64/kernel/traps.c | 12 +- arch/arm64/kvm/hyp/include/hyp/sysreg-sr.h | 10 ++ arch/arm64/kvm/sys_regs.c | 2 + arch/arm64/mm/fault.c | 44 +++++- arch/arm64/mm/mmap.c | 9 ++ arch/arm64/mm/mmu.c | 40 +++++ arch/arm64/tools/cpucaps | 1 + arch/arm64/tools/sysreg | 15 +- arch/powerpc/include/asm/page.h | 11 ++ arch/x86/include/asm/page.h | 10 ++ fs/proc/task_mmu.c | 2 + include/linux/mm.h | 13 -- include/uapi/linux/elf.h | 1 + tools/testing/selftests/arm64/abi/hwcap.c | 14 ++ .../testing/selftests/arm64/signal/.gitignore | 1 + .../arm64/signal/testcases/poe_siginfo.c | 86 +++++++++++ .../arm64/signal/testcases/testcases.c | 27 +--- .../arm64/signal/testcases/testcases.h | 28 +++- .../selftests/kvm/aarch64/get-reg-list.c | 14 ++ tools/testing/selftests/mm/Makefile | 2 +- tools/testing/selftests/mm/pkey-arm64.h | 139 ++++++++++++++++++ tools/testing/selftests/mm/pkey-helpers.h | 8 + tools/testing/selftests/mm/pkey-powerpc.h | 3 + tools/testing/selftests/mm/pkey-x86.h | 4 + tools/testing/selftests/mm/protection_keys.c | 109 ++++++++++++-- 51 files changed, 1011 insertions(+), 67 deletions(-) create mode 100644 arch/arm64/include/asm/pkeys.h create mode 100644 arch/arm64/include/asm/por.h create mode 100644 tools/testing/selftests/arm64/signal/testcases/poe_siginfo.c create mode 100644 tools/testing/selftests/mm/pkey-arm64.h -- 2.25.1

KUnit tests often need to provide a struct device, and thus far have mostly been using root_device_register() or platform devices to create a 'fake device' for use with, e.g., code which uses device-managed resources. This has several disadvantages, including not being designed for test use, scattering files in sysfs, and requiring manual teardown on test exit, which may not always be possible in case of failure. Instead, introduce a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit -- i.e., they will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. This is a follow-up to a previous proposal here: https://lore.kernel.org/linux-kselftest/20230325043104.3761770-1-davidgow@g… (The kunit_defer() function in the first patch there has since been merged as the 'deferred actions' feature.) My intention is to take this whole series in via the kselftest/kunit branch, but I'm equally okay with splitting up the later patches which use this to go via the various subsystem trees in case there are merge conflicts. I'd really appreciate any extra scrutiny that can be given to this; particularly around the device refcounts and whether we can guarantee that the device will be released at the correct point in the test cleanup. I've seen a few crashes in kunit_cleanup, but only on some already flaky/fragile UML/clang/alltests setups, which seem to go away if I remove the devm_add_action() call (or if I enable any debugging features / symbols, annoyingly). Cheers, -- David Signed-off-by: David Gow <davidgow(a)google.com> --- Changes in v2: - Simplify device/driver/bus matching, removing the no-longer-required kunit_bus_match function. (Thanks, Greg) - The return values are both more consistent (kunit_device_register now returns an explicit error pointer, rather than failing the test), and better documented. - Add some basic documentation to the implementations as well as the headers. The documentation in the headers is still more complete, and is now properly compiled into the HTML documentation (under dev-tools/kunit/api/resources.html). (Thanks, Matti) - Moved the internal-only kunit_bus_init() function to a private header, lib/kunit/device-impl.h to avoid polluting the public headers, and match other internal-only headers. (Thanks, Greg) - Alphabetise KUnit includes in other test modules. (Thanks, Amadeusz.) - Several code cleanups, particularly around error handling and allocation. (Thanks Greg, Maxime) - Several const-correctness and casting improvements. (Thanks, Greg) - Added a new test to verify KUnit cleanup triggers device cleanup. (Thanks, Maxime). - Improved the user-specified device test to verify that probe/remove hooks are called correctly. (Thanks, Maxime). - The overflow test no-longer needlessly calls kunit_device_unregister(). - Several other minor cleanups and documentation improvements, which hopefully make this a bit clearer and more robust. - Link to v1: https://lore.kernel.org/r/20231205-kunit_bus-v1-0-635036d3bc13@google.com --- David Gow (4): kunit: Add APIs for managing devices fortify: test: Use kunit_device overflow: Replace fake root_device with kunit_device ASoC: topology: Replace fake root_device with kunit_device in tests Documentation/dev-tools/kunit/api/resource.rst | 9 ++ Documentation/dev-tools/kunit/usage.rst | 50 +++++++ include/kunit/device.h | 80 +++++++++++ lib/fortify_kunit.c | 5 +- lib/kunit/Makefile | 3 +- lib/kunit/device.c | 181 +++++++++++++++++++++++++ lib/kunit/kunit-test.c | 134 +++++++++++++++++- lib/kunit/test.c | 3 + lib/overflow_kunit.c | 5 +- sound/soc/soc-topology-test.c | 10 +- 10 files changed, 465 insertions(+), 15 deletions(-) --- base-commit: c8613be119892ccceffbc550b9b9d7d68b995c9e change-id: 20230718-kunit_bus-ab19c4ef48dc Best regards, -- David Gow <davidgow(a)google.com>

[PATCH RESEND v3] KVM: selftests: Initialise dynamically allocated configuration names

by Mark Brown

When we dynamically generate a name for a configuration in get-reg-list we use strcat() to append to a buffer allocated using malloc() but we never initialise that buffer. Since malloc() offers no guarantees regarding the contents of the memory it returns this can lead to us corrupting, and likely overflowing, the buffer: vregs: PASS vregs+pmu: PASS sve: PASS sve+pmu: PASS vregs+pauth_address+pauth_generic: PASS X�vr+gspauth_addre+spauth_generi+pmu: PASS Initialise the buffer to an empty string to avoid this.

[PATCH v2 0/5] selftests/damon: add Python-written DAMON functionality tests

by SeongJae Park

Changes from v1 (https://lore.kernel.org/damon/20231212191206.52917-1-sj@kernel.org/) - Fix conflicts on latest mm-unstable tree Changes from RFC (https://lore.kernel.org/damon/20231202000806.46210-1-sj@kernel.org/) - Make the working set size estimation test more reliable - Wordsmith coverletter and commit messages - Rename _damon.py to _damon_sysfs.py DAMON exports most of its functionality via its sysfs interface. Hence most DAMON functionality tests could be implemented using the interface. However, because the interfaces require simple but multiple operations for many controls, writing all such tests from the scratch could be repetitive and time consuming. Implement a minimum DAMON sysfs control module, and a couple of DAMON functionality tests using the control module. The first test is for ensuring minimum accuracy of data access monitoring, and the second test is for finding if a previously found and fixed bug is introduced again. Note that the DAMON sysfs control module is only for avoiding duplicating code in tests. For convenient and general control of DAMON, users should use DAMON user-space tools that developed for the purpose, such as damo[1].

[PATCH] tracing/selftests: Add test to test max subbuf size with trace_marker

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> Now that the trace_marker can write up to the max size of the sub buffer. Add a test to see if it actually can happen. The README is updated to state that the trace_marker writes can be broken up, and the test checks the README for that statement so that it does not fail on older kernels that does not support this. If the README does not have the specified update, the test will still test if all the string is written (although it would be broken up), as that should work with older kernels.

[PATCH] Revert "selftests: error out if kernel header files are not yet built"

by John Hubbard

This reverts commit 9fc96c7c19df ("selftests: error out if kernel header files are not yet built"). It turns out that requiring the kernel headers to be built as a prerequisite to building selftests, does not work in many cases. For example, Peter Zijlstra writes: "My biggest beef with the whole thing is that I simply do not want to use 'make headers', it doesn't work for me. I have a ton of output directories and I don't care to build tools into the output dirs, in fact some of them flat out refuse to work that way (bpf comes to mind)." [1] Therefore, stop erroring out on the selftests build. Additional patches will be required in order to change over to not requiring the kernel headers.

[PATCH v3 1/6] kunit: move KUNIT_TABLE out of INIT_DATA

by Rae Moar

Alter the linker section of KUNIT_TABLE to move it out of INIT_DATA and into DATA_DATA. Data for KUnit tests does not need to be in the init section. In order to run tests again after boot the KUnit data cannot be labeled as init data as the kernel could write over it. Add a KUNIT_INIT_TABLE in the next patch for KUnit tests that test init data/functions.

[PATCH] kselftest/arm64: Log SVCR when the SME tests barf

On failure we log the actual and expected value of the register we detect a mismatch in.

[PATCH] kselftest/arm64: Improve output for skipped TPIDR2 ABI test

by Mark Brown

When TPIDR2 is not supported the tpidr2 ABI test prints the same message for each skipped test: ok 1 skipped, TPIDR2 not supported which isn't ideal for test automation software since it tracks kselftest results based on the string used to describe the test. This is also not standard KTAP output, the expected format is: ok 1 # SKIP default_value Updated the program to generate this, using the same set of test names that we would run if the test actually executed.

[RFC PATCH v2 0/7] tun: Introduce virtio-net hashing feature

by Akihiko Odaki

virtio-net have two usage of hashes: one is RSS and another is hash reporting. Conventionally the hash calculation was done by the VMM. However, computing the hash after the queue was chosen defeats the purpose of RSS. Another approach is to use eBPF steering program. This approach has another downside: it cannot report the calculated hash due to the restrictive nature of eBPF. Extend the steering program feature by introducing a dedicated program type: BPF_PROG_TYPE_VNET_HASH. This program type is capable to report the hash value and the queue to use at the same time. This is a rewrite of a RFC patch series submitted by Yuri Benditovich that incorporates feedbacks for the series and V1 of this series: https://lore.kernel.org/lkml/20210112194143.1494-1-yuri.benditovich@daynix.… QEMU patched to use this new feature is available at: https://github.com/daynix/qemu/tree/akihikodaki/bpf The QEMU patches will soon be submitted to the upstream as RFC too.

[PATCH RFT v4 0/5] fork: Support shadow stacks in clone3()

by Mark Brown

The kernel has recently added support for shadow stacks, currently x86 only using their CET feature but both arm64 and RISC-V have equivalent features (GCS and Zicfiss respectively), I am actively working on GCS[1]. With shadow stacks the hardware maintains an additional stack containing only the return addresses for branch instructions which is not generally writeable by userspace and ensures that any returns are to the recorded addresses. This provides some protection against ROP attacks and making it easier to collect call stacks. These shadow stacks are allocated in the address space of the userspace process. Our API for shadow stacks does not currently offer userspace any flexiblity for managing the allocation of shadow stacks for newly created threads, instead the kernel allocates a new shadow stack with the same size as the normal stack whenever a thread is created with the feature enabled. The stacks allocated in this way are freed by the kernel when the thread exits or shadow stacks are disabled for the thread. This lack of flexibility and control isn't ideal, in the vast majority of cases the shadow stack will be over allocated and the implicit allocation and deallocation is not consistent with other interfaces. As far as I can tell the interface is done in this manner mainly because the shadow stack patches were in development since before clone3() was implemented. Since clone3() is readily extensible let's add support for specifying a shadow stack when creating a new thread or process in a similar manner to how the normal stack is specified, keeping the current implicit allocation behaviour if one is not specified either with clone3() or through the use of clone(). Unlike normal stacks only the shadow stack size is specified, similar issues to those that lead to the creation of map_shadow_stack() apply. Please note that the x86 portions of this code are build tested only, I don't appear to have a system that can run CET avaible to me, I have done testing with an integration into my pending work for GCS. There is some possibility that the arm64 implementation may require the use of clone3() and explicit userspace allocation of shadow stacks, this is still under discussion. A new architecture feature Kconfig option for shadow stacks is added as here, this was suggested as part of the review comments for the arm64 GCS series and since we need to detect if shadow stacks are supported it seemed sensible to roll it in here.

[PATCH v1 00/23] Enable FRED with KVM VMX

by Xin Li

This patch set enables the Intel flexible return and event delivery (FRED) architecture with KVM VMX to allow guests to utilize FRED. The FRED architecture defines simple new transitions that change privilege level (ring transitions). The FRED architecture was designed with the following goals: 1) Improve overall performance and response time by replacing event delivery through the interrupt descriptor table (IDT event delivery) and event return by the IRET instruction with lower latency transitions. 2) Improve software robustness by ensuring that event delivery establishes the full supervisor context and that event return establishes the full user context. The new transitions defined by the FRED architecture are FRED event delivery and, for returning from events, two FRED return instructions. FRED event delivery can effect a transition from ring 3 to ring 0, but it is used also to deliver events incident to ring 0. One FRED instruction (ERETU) effects a return from ring 0 to ring 3, while the other (ERETS) returns while remaining in ring 0. Collectively, FRED event delivery and the FRED return instructions are FRED transitions. Intel VMX architecture is extended to run FRED guests, and the changes are majorly: 1) New VMCS fields for FRED context management, which includes two new event data VMCS fields, eight new guest FRED context VMCS fields and eight new host FRED context VMCS fields. 2) VMX nested-Exception support for proper virtualization of stack levels introduced with FRED architecture. Search for the latest FRED spec in most search engines with this search pattern: site:intel.com FRED (flexible return and event delivery) specification We want to send out the FRED VMX patch set for review while the FRED native patch set v12 is being reviewed @ https://lkml.kernel.org/kvm/20231003062458.23552-1-xin3.li@intel.com/. For easier review, I have set up a base tree with the latest FRED native patch set on top of tip tree in the 'fred_v12' branch of repo https://github.com/xinli-intel/linux-fred-public.git.

[RFC PATCH v3 00/12] Device Memory TCP

by Mina Almasry

Changes in RFC v3: ------------------ 1. Pulled in the memory-provider dependency from Jakub's RFC[1] to make the series reviewable and mergable. 2. Implemented multi-rx-queue binding which was a todo in v2. 3. Fix to cmsg handling. The sticking point in RFC v2[2] was the device reset required to refill the device rx-queues after the dmabuf bind/unbind. The solution suggested as I understand is a subset of the per-queue management ops Jakub suggested or similar: https://lore.kernel.org/netdev/20230815171638.4c057dcd@kernel.org/ This is not addressed in this revision, because: 1. This point was discussed at netconf & netdev and there is openness to using the current approach of requiring a device reset. 2. Implementing individual queue resetting seems to be difficult for my test bed with GVE. My prototype to test this ran into issues with the rx-queues not coming back up properly if reset individually. At the moment I'm unsure if it's a mistake in the POC or a genuine issue in the virtualization stack behind GVE, which currently doesn't test individual rx-queue restart. 3. Our usecases are not bothered by requiring a device reset to refill the buffer queues, and we'd like to support NICs that run into this limitation with resetting individual queues. My thought is that drivers that have trouble with per-queue configs can use the support in this series, while drivers that support new netdev ops to reset individual queues can automatically reset the queue as part of the dma-buf bind/unbind. The same approach with device resets is presented again for consideration with other sticking points addressed. This proposal includes the rx devmem path only proposed for merge. For a snapshot of my entire tree which includes the GVE POC page pool support & device memory support: https://github.com/torvalds/linux/compare/master...mina:linux:tcpdevmem-v3 [1] https://lore.kernel.org/netdev/f8270765-a27b-6ccf-33ea-cda097168d79@redhat.… [2] https://lore.kernel.org/netdev/CAHS8izOVJGJH5WF68OsRWFKJid1_huzzUK+hpKbLcL4… Cc: Shakeel Butt <shakeelb(a)google.com> Cc: Jeroen de Borst <jeroendb(a)google.com> Cc: Praveen Kaligineedi <pkaligineedi(a)google.com> Changes in RFC v2: ------------------ The sticking point in RFC v1[1] was the dma-buf pages approach we used to deliver the device memory to the TCP stack. RFC v2 is a proof-of-concept that attempts to resolve this by implementing scatterlist support in the networking stack, such that we can import the dma-buf scatterlist directly. This is the approach proposed at a high level here[2]. Detailed changes: 1. Replaced dma-buf pages approach with importing scatterlist into the page pool. 2. Replace the dma-buf pages centric API with a netlink API. 3. Removed the TX path implementation - there is no issue with implementing the TX path with scatterlist approach, but leaving out the TX path makes it easier to review. 4. Functionality is tested with this proposal, but I have not conducted perf testing yet. I'm not sure there are regressions, but I removed perf claims from the cover letter until they can be re-confirmed. 5. Added Signed-off-by: contributors to the implementation. 6. Fixed some bugs with the RX path since RFC v1. Any feedback welcome, but specifically the biggest pending questions needing feedback IMO are: 1. Feedback on the scatterlist-based approach in general. 2. Netlink API (Patch 1 & 2). 3. Approach to handle all the drivers that expect to receive pages from the page pool (Patch 6). [1] https://lore.kernel.org/netdev/dfe4bae7-13a0-3c5d-d671-f61b375cb0b4@gmail.c… [2] https://lore.kernel.org/netdev/CAHS8izPm6XRS54LdCDZVd0C75tA1zHSu6jLVO8nzTLX… ---------------------- * TL;DR: Device memory TCP (devmem TCP) is a proposal for transferring data to and/or from device memory efficiently, without bouncing the data to a host memory buffer. * Problem: A large amount of data transfers have device memory as the source and/or destination. Accelerators drastically increased the volume of such transfers. Some examples include: - ML accelerators transferring large amounts of training data from storage into GPU/TPU memory. In some cases ML training setup time can be as long as 50% of TPU compute time, improving data transfer throughput & efficiency can help improving GPU/TPU utilization. - Distributed training, where ML accelerators, such as GPUs on different hosts, exchange data among them. - Distributed raw block storage applications transfer large amounts of data with remote SSDs, much of this data does not require host processing. Today, the majority of the Device-to-Device data transfers the network are implemented as the following low level operations: Device-to-Host copy, Host-to-Host network transfer, and Host-to-Device copy. The implementation is suboptimal, especially for bulk data transfers, and can put significant strains on system resources, such as host memory bandwidth, PCIe bandwidth, etc. One important reason behind the current state is the kernel’s lack of semantics to express device to network transfers. * Proposal: In this patch series we attempt to optimize this use case by implementing socket APIs that enable the user to: 1. send device memory across the network directly, and 2. receive incoming network packets directly into device memory. Packet _payloads_ go directly from the NIC to device memory for receive and from device memory to NIC for transmit. Packet _headers_ go to/from host memory and are processed by the TCP/IP stack normally. The NIC _must_ support header split to achieve this. Advantages: - Alleviate host memory bandwidth pressure, compared to existing network-transfer + device-copy semantics. - Alleviate PCIe BW pressure, by limiting data transfer to the lowest level of the PCIe tree, compared to traditional path which sends data through the root complex. * Patch overview: ** Part 1: netlink API Gives user ability to bind dma-buf to an RX queue. ** Part 2: scatterlist support Currently the standard for device memory sharing is DMABUF, which doesn't generate struct pages. On the other hand, networking stack (skbs, drivers, and page pool) operate on pages. We have 2 options: 1. Generate struct pages for dmabuf device memory, or, 2. Modify the networking stack to process scatterlist. Approach #1 was attempted in RFC v1. RFC v2 implements approach #2. ** part 3: page pool support We piggy back on page pool memory providers proposal: https://github.com/kuba-moo/linux/tree/pp-providers It allows the page pool to define a memory provider that provides the page allocation and freeing. It helps abstract most of the device memory TCP changes from the driver. ** part 4: support for unreadable skb frags Page pool iovs are not accessible by the host; we implement changes throughput the networking stack to correctly handle skbs with unreadable frags. ** Part 5: recvmsg() APIs We define user APIs for the user to send and receive device memory. Not included with this RFC is the GVE devmem TCP support, just to simplify the review. Code available here if desired: https://github.com/mina/linux/tree/tcpdevmem This RFC is built on top of net-next with Jakub's pp-providers changes cherry-picked. * NIC dependencies: 1. (strict) Devmem TCP require the NIC to support header split, i.e. the capability to split incoming packets into a header + payload and to put each into a separate buffer. Devmem TCP works by using device memory for the packet payload, and host memory for the packet headers. 2. (optional) Devmem TCP works better with flow steering support & RSS support, i.e. the NIC's ability to steer flows into certain rx queues. This allows the sysadmin to enable devmem TCP on a subset of the rx queues, and steer devmem TCP traffic onto these queues and non devmem TCP elsewhere. The NIC I have access to with these properties is the GVE with DQO support running in Google Cloud, but any NIC that supports these features would suffice.

[PATCH] kunit: test: Use an action wrapper instead of a cast

We missed one of the casts of kfree() to kunit_action_t in kunit-test, which was only enabled when debugfs was in use. This could potentially break CFI. Use the existing wrapper function instead.

[PATCH v3 1/2] kunit: tool: fix parsing of test attributes

by Rae Moar

Add parsing of attributes as diagnostic data. Fixes issue with test plan being parsed incorrectly as diagnostic data when located after suite-level attributes.

[PATCH] maple_tree: Fix mas_prev() state separation code

by Liam R. Howlett

mas_prev() was setting the ma_underflow condition when the limit was reached and not when the limit was attempting to go lower. This resulted in the incorrect behaviour on subsequent actions.

[PATCH] kselftest: dt: Stop relying on dirname to improve performance

by Nícolas F. R. A. Prado

When walking directory trees, instead of looking for specific files and running dirname to get the parent folder, traverse all folders and ignore the ones not containing the desired files. This avoids the need to call dirname inside the loop, which gives a big performance boost, approximately halving run time: Running locally on a mt8192-asurada-spherion, which reports 160 test cases, has gone from 5.5s to 2.9s, while running remotely with an nfsroot has gone from 13.5s to 5.5s. This change has a side-effect, which is that the root DT node now also shows in the output, even though it isn't expected to bind to a driver. However there shouldn't be a matching driver for the board compatible, so the end result will be just an extra skipped test: ok 1 / # SKIP Reported-by: Mark Brown <broonie(a)kernel.org> Closes: https://lore.kernel.org/all/310391e8-fdf2-4c2f-a680-7744eb685177@sirena.org… Fixes: 14571ab1ad21 ("kselftest: Add new test for detecting unprobed Devicetree devices") Signed-off-by: Nícolas F.

[PATCH v2 3/3] selftest/bpf: Test a perf bpf program that suppresses side effects.

by Kyle Huey

The test sets a hardware breakpoint and uses a bpf program to suppress the side effects of a perf event sample, including I/O availability signals, SIGTRAPs, and decrementing the event counter limit, if the ip matches the expected value. Then the function with the breakpoint is executed multiple times to test that all effects behave as expected.

[PATCH v1] KVM: selftests: Fix Assertion on non-x86_64 platforms

KVM_SET_USER_MEMORY_REGION should have failed on v2 only flag 0x2 This is because the arm64 platform also support the KVM_MEM_READONLY flag, but the current implementation add it into the supportd_flags only on x86_64 platform, so this causes assert on other platform which also support the KVM_MEM_READONLY flag. Fix it by using the __KVM_HAVE_READONLY_MEM macro to detect if the current platform support the KVM_MEM_READONLY, thus fix this problem on all other platform which support KVM_MEM_READONLY.

[PATCH v3 0/3] Add a test to catch unprobed Devicetree devices

by Nícolas F. R. A. Prado

Regressions that cause a device to no longer be probed by a driver can have a big impact on the platform's functionality, and despite being relatively common there isn't currently any generic test to detect them. As an example, bootrr [1] does test for device probe, but it requires defining the expected probed devices for each platform. Given that the Devicetree already provides a static description of devices on the system, it is a good basis for building such a test on top. This series introduces a test to catch regressions that prevent devices from probing. Patches 1 and 2 extend the existing dt-extract-compatibles to be able to output only the compatibles that can be expected to match a Devicetree node to a driver. Patch 2 adds a kselftest that walks over the Devicetree nodes on the current platform and compares the compatibles to the ones on the list, and on an ignore list, to point out devices that failed to be probed. A compatible list is needed because not all compatibles that can show up in a Devicetree node can be used to match to a driver, for example the code for that compatible might use "OF_DECLARE" type macros and avoid the driver framework, or the node might be controlled by a driver that was bound to a different node. An ignore list is needed for the few cases where it's common for a driver to match a device but not probe, like for the "simple-mfd" compatible, where the driver only probes if that compatible is the node's first compatible. The reason for parsing the kernel source instead of relying on information exposed by the kernel at runtime (say, looking at modaliases or introducing some other mechanism), is to be able to catch issues where a config was renamed or a driver moved across configs, and the .config used by the kernel not updated accordingly. We need to parse the source to find all compatibles present in the kernel independent of the current config being run. [1] https://github.com/kernelci/bootrr Changes in v3: - Added DT selftest path to MAINTAINERS - Enabled device probe test for nodes with 'status = "ok"' - Added pass/fail/skip totals to end of test output Changes in v2: - Extended dt-extract-compatibles script to be able to extract driver matching compatibles, instead of adding a new one in Coccinelle - Made kselftest output in the KTAP format Nícolas F.

[PATCH 0/4] kunit: Add helpers for creating test-managed devices

by davidgow＠google.com

KUnit tests often need to provide a struct device, and thus far have mostly been using root_device_register() or platform devices to create a 'fake device' for use with, e.g., code which uses device-managed resources. This has several disadvantages, including not being designed for test use, scattering files in sysfs, and requiring manual teardown on test exit, which may not always be possible in case of failure. Instead, introduce a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit -- i.e., they will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. This is a follow-up to a previous proposal here: https://lore.kernel.org/linux-kselftest/20230325043104.3761770-1-davidgow@g… (The kunit_defer() function in the first patch there has since been merged as the 'deferred actions' feature.) My intention is to take this whole series in via the kselftest/kunit branch, but I'm equally okay with splitting up the later patches which use this to go via the various subsystem trees in case there are merge conflicts.

[PATCH v2 1/2] kunit: tool: fix parsing of test attributes

by Rae Moar

Add parsing of attributes as diagnostic data. Fixes issue with test plan being parsed incorrectly as diagnostic data when located after suite-level attributes. Note that if there does not exist a test plan line, the diagnostic lines between the suite header and the first result will be saved in the suite log rather than the first test case log.

[PATCH v8 0/6] workload-specific and memory pressure-driven zswap writeback

by Nhat Pham

Changelog: v8: * Fixed a couple of build errors in the case of !CONFIG_MEMCG * Simplified the online memcg selection scheme for the zswap global limit reclaim (suggested by Michal Hocko and Johannes Weiner) (patch 2 and patch 3) * Added a new kconfig to allows users to enable zswap shrinker by default. (suggested by Johannes Weiner) (patch 6) v7: * Added the mem_cgroup_iter_online() function to the API for the new behavior (suggested by Andrew Morton) (patch 2) * Fixed a missing list_lru_del -> list_lru_del_obj (patch 1) v6: * Rebase on top of latest mm-unstable. * Fix/improve the in-code documentation of the new list_lru manipulation functions (patch 1) v5: * Replace reference getting with an rcu_read_lock() section for zswap lru modifications (suggested by Yosry) * Add a new prep patch that allows mem_cgroup_iter() to return online cgroup. * Add a callback that updates pool->next_shrink when the cgroup is offlined (suggested by Yosry Ahmed, Johannes Weiner) v4: * Rename list_lru_add to list_lru_add_obj and __list_lru_add to list_lru_add (patch 1) (suggested by Johannes Weiner and Yosry Ahmed) * Some cleanups on the memcg aware LRU patch (patch 2) (suggested by Yosry Ahmed) * Use event interface for the new per-cgroup writeback counters. (patch 3) (suggested by Yosry Ahmed) * Abstract zswap's lruvec states and handling into zswap_lruvec_state (patch 5) (suggested by Yosry Ahmed) v3: * Add a patch to export per-cgroup zswap writeback counters * Add a patch to update zswap's kselftest * Separate the new list_lru functions into its own prep patch * Do not start from the top of the hierarchy when encounter a memcg that is not online for the global limit zswap writeback (patch 2) (suggested by Yosry Ahmed) * Do not remove the swap entry from list_lru in __read_swapcache_async() (patch 2) (suggested by Yosry Ahmed) * Removed a redundant zswap pool getting (patch 2) (reported by Ryan Roberts) * Use atomic for the nr_zswap_protected (instead of lruvec's lock) (patch 5) (suggested by Yosry Ahmed) * Remove the per-cgroup zswap shrinker knob (patch 5) (suggested by Yosry Ahmed) v2: * Fix loongarch compiler errors * Use pool stats instead of memcg stats when !CONFIG_MEMCG_KEM There are currently several issues with zswap writeback: 1. There is only a single global LRU for zswap, making it impossible to perform worload-specific shrinking - an memcg under memory pressure cannot determine which pages in the pool it owns, and often ends up writing pages from other memcgs. This issue has been previously observed in practice and mitigated by simply disabling memcg-initiated shrinking: https://lore.kernel.org/all/20230530232435.3097106-1-nphamcs@gmail.com/T/#u But this solution leaves a lot to be desired, as we still do not have an avenue for an memcg to free up its own memory locked up in the zswap pool. 2. We only shrink the zswap pool when the user-defined limit is hit. This means that if we set the limit too high, cold data that are unlikely to be used again will reside in the pool, wasting precious memory. It is hard to predict how much zswap space will be needed ahead of time, as this depends on the workload (specifically, on factors such as memory access patterns and compressibility of the memory pages). This patch series solves these issues by separating the global zswap LRU into per-memcg and per-NUMA LRUs, and performs workload-specific (i.e memcg- and NUMA-aware) zswap writeback under memory pressure. The new shrinker does not have any parameter that must be tuned by the user, and can be opted in or out on a per-memcg basis. As a proof of concept, we ran the following synthetic benchmark: build the linux kernel in a memory-limited cgroup, and allocate some cold data in tmpfs to see if the shrinker could write them out and improved the overall performance. Depending on the amount of cold data generated, we observe from 14% to 35% reduction in kernel CPU time used in the kernel builds.

[PATCH v2 00/26] selftests/resctrl: CAT test improvements & generalized test framework

by Ilpo Järvinen

Hi all, Here's v2 series to improve resctrl selftests with generalized test framework and rewritten CAT test. In contrast to v1, this version does not include L2 CAT test because it needs further work. In general, I feel that v2 is in much better shape than v1 because I ended up addressing a few small things beyond what came up during v1 review. The series contains following improvements: - Excludes shareable bits from CAT test allocation to avoid interference - Replaces file "sink" with a volatile variable - Alters read pattern to defeat HW prefetcher optimizations - Rewrites CAT test to make the CAT test reliable and truly measure if CAT is working or not - Introduces generalized test framework making easier to add new tests - Lots of other cleanups & refactoring This series have been tested across a large number of systems from different generations. v2: - Postpone adding L2 CAT test as more investigations are necessary - Add patch to remove ctrlc_handler() from wrong place - Improvements to changelogs - Function comments improvements & comment cleanups - Move some parts of the changes into more logical patch - If checks: buf == NULL -> !buf - Variable naming: - p -> buf - cbm_mask_path -> cbm_path - Function naming: - get_cbm_mask() -> get_full_cbm() - cache_size() -> cache_portion_size() - Use PATH_MAX - Improved cache_portion_size() parameter names - int count -> unsigned int - Pass filename to measurement taking functions instead of resctrl_val_param - !lines ? : reversal - Removed bogus static from function local variable - Open perf fd only once, reset & enable in the innermost test loop - Add perf fd ioctl() error handling - Add patch to change compiler optimization prevention "sink" from file to volatile variable - Remove cpu_no and resource (the latter was added in v1) members from resctrl_val_param (pass uparams and test where those are needed) - Removed ARRAY_SIZE() macro - Add patch to rename "resource_id" to "domain_id" Ilpo Järvinen (26): selftests/resctrl: Don't use ctrlc_handler() outside signal handling selftests/resctrl: Split fill_buf to allow tests finer-grained control selftests/resctrl: Refactor fill_buf functions selftests/resctrl: Refactor get_cbm_mask() and rename to get_full_cbm() selftests/resctrl: Mark get_cache_size() cache_type const selftests/resctrl: Create cache_portion_size() helper selftests/resctrl: Exclude shareable bits from schemata in CAT test selftests/resctrl: Split measure_cache_vals() selftests/resctrl: Split show_cache_info() to test specific and generic parts selftests/resctrl: Remove unnecessary __u64 -> unsigned long conversion selftests/resctrl: Remove nested calls in perf event handling selftests/resctrl: Consolidate naming of perf event related things selftests/resctrl: Improve perf init selftests/resctrl: Convert perf related globals to locals selftests/resctrl: Move cat_val() to cat_test.c and rename to cat_test() selftests/resctrl: Open perf fd before start & add error handling selftests/resctrl: Replace file write with volatile variable selftests/resctrl: Read in less obvious order to defeat prefetch optimizations selftests/resctrl: Rewrite Cache Allocation Technology (CAT) test selftests/resctrl: Create struct for input parameters selftests/resctrl: Introduce generalized test framework selftests/resctrl: Pass write_schemata() resource instead of test name selftests/resctrl: Add helper to convert L2/3 to integer selftests/resctrl: Rename resource ID to domain ID selftests/resctrl: Get domain id from cache id selftests/resctrl: Add test groups and name L3 CAT test L3_CAT tools/testing/selftests/resctrl/cache.c | 274 +++++---------- tools/testing/selftests/resctrl/cat_test.c | 328 +++++++++++------- tools/testing/selftests/resctrl/cmt_test.c | 76 +++- tools/testing/selftests/resctrl/fill_buf.c | 132 ++++--- tools/testing/selftests/resctrl/mba_test.c | 26 +- tools/testing/selftests/resctrl/mbm_test.c | 28 +- tools/testing/selftests/resctrl/resctrl.h | 117 +++++-- .../testing/selftests/resctrl/resctrl_tests.c | 205 +++++------ tools/testing/selftests/resctrl/resctrl_val.c | 56 +-- tools/testing/selftests/resctrl/resctrlfs.c | 246 ++++++++----- 10 files changed, 821 insertions(+), 667 deletions(-) -- 2.30.2

[PATCH v3 00/21] arm64: Support for 2023 DPISA extensions

by Mark Brown

This series enables support for the data processing extensions in the newly released 2023 architecture, this is mainly support for 8 bit floating point formats. Most of the extensions only introduce new instructions and therefore only require hwcaps but there is a new EL0 visible control register FPMR used to control the 8 bit floating point formats, we need to manage traps for this and context switch it. The sharing of floating point save code between the host and guest kernels slightly complicates the introduction of KVM support, we first introduce host support with some placeholders for KVM then replace those with the actual KVM support. I've not added test coverage for ptrace, I've got a not quite finished test program which exercises all the FP ptrace interfaces and their interactions together, my plan is to cover it there rather than add another tiny test program that duplicates the boilerplace for tracing a target and doesn't actually run the traced program.

[PATCHv3 net-next 00/14] Conver net selftests to run in unique namespace (Part 1)

by Hangbin Liu

As Guillaume pointed, many selftests create namespaces with very common names (like "client" or "server") or even (partially) run directly in init_net. This makes these tests prone to failure if another namespace with the same name already exists. It also makes it impossible to run several instances of these tests in parallel. This patch set intend to conver all the net selftests to run in unique namespace, so we can update the selftest freamwork to run all tests in it's own namespace in parallel. After update, we only need to wait for the test which need longest time. As the total patch set is too large. I break it to severl parts. This is the first part. v2 -> v3: - Convert all ip netns del to cleanup_ns (Justin Iurman) v1 -> v2: - Split the large patch set to small parts for easy review (Paolo Abeni) - Move busywait from forwarding/lib.sh to net/lib.sh directly (Petr Machata) - Update setup_ns/cleanup_ns struct (Petr Machata) - Remove default trap in lib.sh (Petr Machata) Hangbin Liu (14): selftests/net: add lib.sh selftests/net: convert arp_ndisc_evict_nocarrier.sh to run it in unique namespace selftests/net: specify the interface when do arping selftests/net: convert arp_ndisc_untracked_subnets.sh to run it in unique namespace selftests/net: convert cmsg tests to make them run in unique namespace selftests/net: convert drop_monitor_tests.sh to run it in unique namespace selftests/net: convert traceroute.sh to run it in unique namespace selftests/net: convert icmp_redirect.sh to run it in unique namespace sleftests/net: convert icmp.sh to run it in unique namespace selftests/net: convert ioam6.sh to run it in unique namespace selftests/net: convert l2tp.sh to run it in unique namespace selftests/net: convert ndisc_unsolicited_na_test.sh to run it in unique namespace selftests/net: convert sctp_vrf.sh to run it in unique namespace selftests/net: convert unicast_extensions.sh to run it in unique namespace tools/testing/selftests/net/Makefile | 2 +- .../net/arp_ndisc_evict_nocarrier.sh | 46 ++-- .../net/arp_ndisc_untracked_subnets.sh | 20 +- tools/testing/selftests/net/cmsg_ipv6.sh | 10 +- tools/testing/selftests/net/cmsg_so_mark.sh | 7 +- tools/testing/selftests/net/cmsg_time.sh | 7 +- .../selftests/net/drop_monitor_tests.sh | 21 +- tools/testing/selftests/net/forwarding/lib.sh | 27 +- tools/testing/selftests/net/icmp.sh | 10 +- tools/testing/selftests/net/icmp_redirect.sh | 182 +++++++------ tools/testing/selftests/net/ioam6.sh | 247 +++++++++--------- tools/testing/selftests/net/l2tp.sh | 130 +++++---- tools/testing/selftests/net/lib.sh | 85 ++++++ .../net/ndisc_unsolicited_na_test.sh | 19 +- tools/testing/selftests/net/sctp_vrf.sh | 12 +- tools/testing/selftests/net/traceroute.sh | 82 +++--- .../selftests/net/unicast_extensions.sh | 99 ++++--- 17 files changed, 500 insertions(+), 506 deletions(-) create mode 100644 tools/testing/selftests/net/lib.sh -- 2.43.0

[PATCH v2 00/15] selftests/hid: tablets fixes

by Benjamin Tissoires

Hi, the main trigger of this series was the XP-Pen issue[0]. Basically, the tablets tests were good-ish but couldn't handle that tablet both in terms of emulation or in terms of detection of issues. So rework the tablets test a bit to be able to include the XP-Pen patch later, once I have a kernel fix for it (right now I only have a HID-BPF fix, meaning that the test will fail if I include them). Also, vmtest.sh needed a little bit of care, because boot2container moved, and I made it easier to reuse in a CI environment. Cheers, Benjamin Note: I got the confirmation off-list from Peter that his rev-by applied to the whole series.

[PATCH v1] selftests/sgx: Skip non X86_64 platform

by Zhao Mengmeng

From: Zhao Mengmeng <zhaomengmeng(a)kylinos.cn> When building whole selftests on arm64, rsync gives an erorr about sgx: rsync: [sender] link_stat "/root/linux-next/tools/testing/selftests/sgx/test_encl.elf" failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1327) [sender=3.2.5] The root casue is sgx only used on X86_64, and shall be skipped on other platforms.

[PATCH v1 0/9] x86/resctrl: Use soft RMIDs for reliable MBM on AMD

by Peter Newman

Hi Reinette, Fenghua, This series introduces a new mount option enabling an alternate mode for MBM to work around an issue on present AMD implementations and any other resctrl implementation where there are more RMIDs (or equivalent) than hardware counters. The L3 External Bandwidth Monitoring feature of the AMD PQoS extension[1] only guarantees that RMIDs currently assigned to a processor will be tracked by hardware. The counters of any other RMIDs which are no longer being tracked will be reset to zero. The MBM event counters return "Unavailable" to indicate when this has happened. An interval for effectively measuring memory bandwidth typically needs to be multiple seconds long. In Google's workloads, it is not feasible to bound the number of jobs with different RMIDs which will run in a cache domain over any period of time. Consequently, on a fully-committed system where all RMIDs are allocated, few groups' counters return non-zero values. To demonstrate the underlying issue, the first patch provides a test case in tools/testing/selftests/resctrl/test_rmids.sh. On an AMD EPYC 7B12 64-Core Processor with the default behavior: # ./test_rmids.sh Created 255 monitoring groups. g1: mbm_total_bytes: Unavailable -> Unavailable (FAIL) g2: mbm_total_bytes: Unavailable -> Unavailable (FAIL) g3: mbm_total_bytes: Unavailable -> Unavailable (FAIL) [..] g238: mbm_total_bytes: Unavailable -> Unavailable (FAIL) g239: mbm_total_bytes: Unavailable -> Unavailable (FAIL) g240: mbm_total_bytes: Unavailable -> Unavailable (FAIL) g241: mbm_total_bytes: Unavailable -> 660497472 g242: mbm_total_bytes: Unavailable -> 660793344 g243: mbm_total_bytes: Unavailable -> 660477312 g244: mbm_total_bytes: Unavailable -> 660495360 g245: mbm_total_bytes: Unavailable -> 660775360 g246: mbm_total_bytes: Unavailable -> 660645504 g247: mbm_total_bytes: Unavailable -> 660696128 g248: mbm_total_bytes: Unavailable -> 660605248 g249: mbm_total_bytes: Unavailable -> 660681280 g250: mbm_total_bytes: Unavailable -> 660834240 g251: mbm_total_bytes: Unavailable -> 660440064 g252: mbm_total_bytes: Unavailable -> 660501504 g253: mbm_total_bytes: Unavailable -> 660590720 g254: mbm_total_bytes: Unavailable -> 660548352 g255: mbm_total_bytes: Unavailable -> 660607296 255 groups, 0 returned counts in first pass, 15 in second successfully measured bandwidth from 15/255 groups To compare, here is the output from an Intel(R) Xeon(R) Platinum 8173M CPU: # ./test_rmids.sh Created 223 monitoring groups. g1: mbm_total_bytes: 0 -> 606126080 g2: mbm_total_bytes: 0 -> 613236736 g3: mbm_total_bytes: 0 -> 610254848 [..] g221: mbm_total_bytes: 0 -> 584679424 g222: mbm_total_bytes: 0 -> 588808192 g223: mbm_total_bytes: 0 -> 587317248 223 groups, 223 returned counts in first pass, 223 in second successfully measured bandwidth from 223/223 groups To make better use of the hardware in such a use case, this patchset introduces a "soft" RMID implementation, where each CPU is permanently assigned a "hard" RMID. On context switches which change the current soft RMID, the difference between each CPU's current event counts and most recent counts is added to the totals for the current or outgoing soft RMID. This technique does not work for cache occupancy counters, so this patch series disables cache occupancy events when soft RMIDs are enabled. This series adds the "mbm_soft_rmid" mount option to allow users to opt-in to the functionaltiy when they deem it helpful. When the same system from the earlier AMD example enables the mbm_soft_rmid mount option: # ./test_rmids.sh Created 255 monitoring groups. g1: mbm_total_bytes: 0 -> 686560576 g2: mbm_total_bytes: 0 -> 668204416 [..] g252: mbm_total_bytes: 0 -> 672651200 g253: mbm_total_bytes: 0 -> 666956800 g254: mbm_total_bytes: 0 -> 665917056 g255: mbm_total_bytes: 0 -> 671049600 255 groups, 255 returned counts in first pass, 255 in second successfully measured bandwidth from 255/255 groups (patches are based on tip/master) [1] https://www.amd.com/system/files/TechDocs/56375_1.03_PUB.pdf Peter Newman (8): selftests/resctrl: Verify all RMIDs count together x86/resctrl: Add resctrl_mbm_flush_cpu() to collect CPUs' MBM events x86/resctrl: Flush MBM event counts on soft RMID change x86/resctrl: Call mon_event_count() directly for soft RMIDs x86/resctrl: Create soft RMID version of __mon_event_count() x86/resctrl: Assign HW RMIDs to CPUs for soft RMID x86/resctrl: Use mbm_update() to push soft RMID counts x86/resctrl: Add mount option to enable soft RMID Stephane Eranian (1): x86/resctrl: Hold a spinlock in __rmid_read() on AMD arch/x86/include/asm/resctrl.h | 29 +++- arch/x86/kernel/cpu/resctrl/core.c | 80 ++++++++- arch/x86/kernel/cpu/resctrl/ctrlmondata.c | 9 +- arch/x86/kernel/cpu/resctrl/internal.h | 19 ++- arch/x86/kernel/cpu/resctrl/monitor.c | 158 +++++++++++++++++- arch/x86/kernel/cpu/resctrl/rdtgroup.c | 52 ++++++ tools/testing/selftests/resctrl/test_rmids.sh | 93 +++++++++++ 7 files changed, 425 insertions(+), 15 deletions(-) create mode 100755 tools/testing/selftests/resctrl/test_rmids.sh base-commit: dd806e2f030e57dd5bac973372aa252b6c175b73 -- 2.40.0.634.g4ca3ef3211-goog

[PATCH v2] kunit: run test suites only after module initialization completes

by Marco Pagani

Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed a wild-memory-access bug that could have happened during the loading phase of test suites built and executed as loadable modules. However, it also introduced a problematic side effect that causes test suites modules to crash when they attempt to register fake devices. When a module is loaded, it traverses the MODULE_STATE_UNFORMED and MODULE_STATE_COMING states before reaching the normal operating state MODULE_STATE_LIVE. Finally, when the module is removed, it moves to MODULE_STATE_GOING before being released. However, if the loading function load_module() fails between complete_formation() and do_init_module(), the module goes directly from MODULE_STATE_COMING to MODULE_STATE_GOING without passing through MODULE_STATE_LIVE. This behavior was causing kunit_module_exit() to be called without having first executed kunit_module_init(). Since kunit_module_exit() is responsible for freeing the memory allocated by kunit_module_init() through kunit_filter_suites(), this behavior was resulting in a wild-memory-access bug. Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed this issue by running the tests when the module is still in MODULE_STATE_COMING. However, modules in that state are not fully initialized, lacking sysfs kobjects. Therefore, if a test module attempts to register a fake device, it will inevitably crash. This patch proposes a different approach to fix the original wild-memory-access bug while restoring the normal module execution flow by making kunit_module_exit() able to detect if kunit_module_init() has previously initialized the tests suite set. In this way, test modules can once again register fake devices without crashing. This behavior is achieved by checking whether mod->kunit_suites is a virtual or direct mapping address. If it is a virtual address, then kunit_module_init() has allocated the suite_set in kunit_filter_suites() using kmalloc_array(). On the contrary, if mod->kunit_suites is still pointing to the original address that was set when looking up the .kunit_test_suites section of the module, then the loading phase has failed and there's no memory to be freed. v2: - add include <linux/mm.h> Fixes: 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") Signed-off-by: Marco Pagani <marpagan(a)redhat.com> --- lib/kunit/test.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/lib/kunit/test.c b/lib/kunit/test.c index f2eb71f1a66c..0e829b9f8ce5 100644 --- a/lib/kunit/test.c +++ b/lib/kunit/test.c @@ -16,6 +16,7 @@ #include <linux/panic.h> #include <linux/sched/debug.h> #include <linux/sched.h> +#include <linux/mm.h> #include "debugfs.h" #include "hooks-impl.h" @@ -737,12 +738,14 @@ static void kunit_module_exit(struct module *mod) }; const char *action = kunit_action(); + if (!suite_set.start || !virt_addr_valid(suite_set.start)) + return; + if (!action) __kunit_test_suites_exit(mod->kunit_suites, mod->num_kunit_suites); - if (suite_set.start) - kunit_free_suite_set(suite_set); + kunit_free_suite_set(suite_set); } static int kunit_module_notify(struct notifier_block *nb, unsigned long val, @@ -752,12 +755,12 @@ static int kunit_module_notify(struct notifier_block *nb, unsigned long val, switch (val) { case MODULE_STATE_LIVE: + kunit_module_init(mod); break; case MODULE_STATE_GOING: kunit_module_exit(mod); break; case MODULE_STATE_COMING: - kunit_module_init(mod); break; case MODULE_STATE_UNFORMED: break; base-commit: 2cc14f52aeb78ce3f29677c2de1f06c0e91471ab -- 2.42.0

[PATCH v5 0/5] userfaultfd move option

by Suren Baghdasaryan

This patch series introduces UFFDIO_MOVE feature to userfaultfd, which has long been implemented and maintained by Andrea in his local tree [1], but was not upstreamed due to lack of use cases where this approach would be better than allocating a new page and copying the contents. Previous upstraming attempts could be found at [6] and [7]. UFFDIO_COPY performs ~20% better than UFFDIO_MOVE when the application needs pages to be allocated [2]. However, with UFFDIO_MOVE, if pages are available (in userspace) for recycling, as is usually the case in heap compaction algorithms, then we can avoid the page allocation and memcpy (done by UFFDIO_COPY). Also, since the pages are recycled in the userspace, we avoid the need to release (via madvise) the pages back to the kernel [3]. We see over 40% reduction (on a Google pixel 6 device) in the compacting thread’s completion time by using UFFDIO_MOVE vs. UFFDIO_COPY. This was measured using a benchmark that emulates a heap compaction implementation using userfaultfd (to allow concurrent accesses by application threads). More details of the usecase are explained in [3]. Furthermore, UFFDIO_MOVE enables moving swapped-out pages without touching them within the same vma. Today, it can only be done by mremap, however it forces splitting the vma. TODOs for follow-up improvements: - cross-mm support. Known differences from single-mm and missing pieces: - memcg recharging (might need to isolate pages in the process) - mm counters - cross-mm deposit table moves - cross-mm test - document the address space where src and dest reside in struct uffdio_move - TLB flush batching. Will require extensive changes to PTL locking in move_pages_pte(). OTOH that might let us reuse parts of mremap code. Changes since v4 [9]: - added Acked-by in patch 1, per Peter Xu - added description for ctx, mm and mode parameters of move_pages(), per kernel test robot - added Reviewed-by's, per Peter Xu and Axel Rasmussen - removed unused operations in uffd_test_case_ops - refactored uffd-unit-test changes to avoid using global variables and handle pmd moves without page size overrides, per Peter Xu Changes since v3 [8]: - changed retry path in folio_lock_anon_vma_read() to unlock and then relock RCU, per Peter Xu - removed cross-mm support from initial patchset, per David Hildenbrand - replaced BUG_ONs with VM_WARN_ON or WARN_ON_ONCE, per David Hildenbrand - added missing cache flushing, per Lokesh Gidra and Peter Xu - updated manpage text in the patch description, per Peter Xu - renamed internal functions from "remap" to "move", per Peter Xu - added mmap_changing check after taking mmap_lock, per Peter Xu - changed uffd context check to ensure dst_mm is registered onto uffd we are operating on, Peter Xu and David Hildenbrand - changed to non-maybe variants of maybe*_mkwrite(), per David Hildenbrand - fixed warning for CONFIG_TRANSPARENT_HUGEPAGE=n, per kernel test robot - comments cleanup, per David Hildenbrand and Peter Xu - checks for VM_IO,VM_PFNMAP,VM_HUGETLB,..., per David Hildenbrand - prevent moving pinned pages, per Peter Xu - changed uffd tests to call move uffd_test_ctx_clear() at the end of the test run instead of in the beginning of the next run - added support for testcase-specific ops - added test for moving PMD-aligned blocks Changes since v2 [5]: - renamed UFFDIO_REMAP to UFFDIO_MOVE, per David Hildenbrand - rebase over mm-unstable to use folio_move_anon_rmap(), per David Hildenbrand - added text for manpage explaining DONTFORK and KSM requirements for this feature, per David Hildenbrand - check for anon_vma changes in the fast path of folio_lock_anon_vma_read, per Peter Xu - updated the title and description of the first patch, per David Hildenbrand - updating comments in folio_lock_anon_vma_read() explaining the need for anon_vma checks, per David Hildenbrand - changed all mapcount checks to PageAnonExclusive, per Jann Horn and David Hildenbrand - changed counters in remap_swap_pte() from MM_ANONPAGES to MM_SWAPENTS, per Jann Horn - added a check for PTE change after folio is locked in remap_pages_pte(), per Jann Horn - added handling of PMD migration entries and bailout when pmd_devmap(), per Jann Horn - added checks to ensure both src and dst VMAs are writable, per Peter Xu - added UFFD_FEATURE_MOVE, per Peter Xu - removed obsolete comments, per Peter Xu - renamed remap_anon_pte to remap_present_pte, per Peter Xu - added a comment for folio_get_anon_vma() explaining the need for anon_vma checks, per Peter Xu - changed error handling in remap_pages() to make it more clear, per Peter Xu - changed EFAULT to EAGAIN to retry when a hugepage appears or disappears from under us, per Peter Xu - added links to previous upstreaming attempts, per David Hildenbrand Changes since v1 [4]: - add mmget_not_zero in userfaultfd_remap, per Jann Horn - removed extern from function definitions, per Matthew Wilcox - converted to folios in remap_pages_huge_pmd, per Matthew Wilcox - use PageAnonExclusive in remap_pages_huge_pmd, per David Hildenbrand - handle pgtable transfers between MMs, per Jann Horn - ignore concurrent A/D pte bit changes, per Jann Horn - split functions into smaller units, per David Hildenbrand - test for folio_test_large in remap_anon_pte, per Matthew Wilcox - use pte_swp_exclusive for swapcount check, per David Hildenbrand - eliminated use of mmu_notifier_invalidate_range_start_nonblock, per Jann Horn - simplified THP alignment checks, per Jann Horn - refactored the loop inside remap_pages, per Jann Horn - additional clarifying comments, per Jann Horn Main changes since Andrea's last version [1]: - Trivial translations from page to folio, mmap_sem to mmap_lock - Replace pmd_trans_unstable() with pte_offset_map_nolock() and handle its possible failure - Move pte mapping into remap_pages_pte to allow for retries when source page or anon_vma is contended. Since pte_offset_map_nolock() start RCU read section, we can't block anymore after mapping a pte, so have to unmap the ptesm do the locking and retry. - Add and use anon_vma_trylock_write() to avoid blocking while in RCU read section. - Accommodate changes in mmu_notifier_range_init() API, switch to mmu_notifier_invalidate_range_start_nonblock() to avoid blocking while in RCU read section. - Open-code now removed __swp_swapcount() - Replace pmd_read_atomic() with pmdp_get_lockless() - Add new selftest for UFFDIO_MOVE [1] https://gitlab.com/aarcange/aa/-/commit/2aec7aea56b10438a3881a20a411aa4b1fc… [2] https://lore.kernel.org/all/1425575884-2574-1-git-send-email-aarcange@redha… [3] https://lore.kernel.org/linux-mm/CA+EESO4uO84SSnBhArH4HvLNhaUQ5nZKNKXqxRCyj… [4] https://lore.kernel.org/all/20230914152620.2743033-1-surenb@google.com/ [5] https://lore.kernel.org/all/20230923013148.1390521-1-surenb@google.com/ [6] https://lore.kernel.org/all/1425575884-2574-21-git-send-email-aarcange@redh… [7] https://lore.kernel.org/all/cover.1547251023.git.blake.caldwell@colorado.ed… [8] https://lore.kernel.org/all/20231009064230.2952396-1-surenb@google.com/ [9] https://lore.kernel.org/all/20231028003819.652322-1-surenb@google.com/ Andrea Arcangeli (2): mm/rmap: support move to different root anon_vma in folio_move_anon_rmap() userfaultfd: UFFDIO_MOVE uABI Suren Baghdasaryan (3): selftests/mm: call uffd_test_ctx_clear at the end of the test selftests/mm: add uffd_test_case_ops to allow test case-specific operations selftests/mm: add UFFDIO_MOVE ioctl test Documentation/admin-guide/mm/userfaultfd.rst | 3 + fs/userfaultfd.c | 72 +++ include/linux/rmap.h | 5 + include/linux/userfaultfd_k.h | 11 + include/uapi/linux/userfaultfd.h | 29 +- mm/huge_memory.c | 122 ++++ mm/khugepaged.c | 3 + mm/rmap.c | 30 + mm/userfaultfd.c | 599 +++++++++++++++++++ tools/testing/selftests/mm/uffd-common.c | 39 +- tools/testing/selftests/mm/uffd-common.h | 9 + tools/testing/selftests/mm/uffd-stress.c | 5 +- tools/testing/selftests/mm/uffd-unit-tests.c | 192 ++++++ 13 files changed, 1115 insertions(+), 4 deletions(-) -- 2.43.0.rc1.413.gea7ed67945-goog
