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

by Adrien Thierry

In some conditions, background processes in udpgro don't have enough time to set up the sockets. When foreground processes start, this results in the test failing with "./udpgso_bench_tx: sendmsg: Connection refused". For instance, this happens from time to time on a Qualcomm SA8540P SoC running CentOS Stream 9. To fix this, increase the time given to background processes to complete the startup before foreground processes start. Signed-off-by: Adrien Thierry <athierry(a)redhat.com> --- This is a continuation of the hack that's present in those tests.

[PATCH hid v11 00/14] Introduce eBPF support for HID devices

by Benjamin Tissoires

Hi, and here comes the v11 of the HID-BPF series. Again, for a full explanation of HID-BPF, please refer to the last patch in this series (14/14). Now that the bpf-core changes are all merged in v6.1, it is time to have that series entirely relying on HID, so it can get merged into the HID tree. Compared to v10, the most notable change is in the selftests and the samples: they are now namespaced into hid, not bpf. This means that HID-BPF has no more conflicts with the bpf tree. One other interesting change is in patch 4/14. I managed to reduce the scope of the embedded bpf programs, by tricking the refcount. I am planning on submitting an RFC for embedding those changes in bpf core (a map that doesn't increment refcount and a cleanup mechanism) but this can come as a later improvement. This new kind of maps and mechanisms might also be useful for other subsystems. Cheers, Benjamin Benjamin Tissoires (14): HID: Kconfig: split HID support and hid-core compilation HID: initial BPF implementation selftests: add tests for the HID-bpf initial implementation HID: bpf jmp table: simplify the logic of cleaning up programs HID: bpf: allocate data memory for device_event BPF programs selftests/hid: add test to change the report size HID: bpf: introduce hid_hw_request() selftests/hid: add tests for bpf_hid_hw_request HID: bpf: allow to change the report descriptor selftests/hid: add report descriptor fixup tests selftests/hid: Add a test for BPF_F_INSERT_HEAD samples/hid: add new hid BPF example samples/hid: add Surface Dial example Documentation: add HID-BPF docs Documentation/hid/hid-bpf.rst | 513 +++++++++++ Documentation/hid/index.rst | 1 + MAINTAINERS | 3 + drivers/Makefile | 2 +- drivers/hid/Kconfig | 20 +- drivers/hid/Makefile | 2 + drivers/hid/bpf/Kconfig | 17 + drivers/hid/bpf/Makefile | 11 + drivers/hid/bpf/entrypoints/Makefile | 93 ++ drivers/hid/bpf/entrypoints/README | 4 + drivers/hid/bpf/entrypoints/entrypoints.bpf.c | 34 + .../hid/bpf/entrypoints/entrypoints.lskel.h | 368 ++++++++ drivers/hid/bpf/hid_bpf_dispatch.c | 526 +++++++++++ drivers/hid/bpf/hid_bpf_dispatch.h | 28 + drivers/hid/bpf/hid_bpf_jmp_table.c | 572 ++++++++++++ drivers/hid/hid-core.c | 32 +- include/linux/hid.h | 5 + include/linux/hid_bpf.h | 148 +++ include/uapi/linux/hid_bpf.h | 25 + samples/hid/.gitignore | 8 + samples/hid/Makefile | 246 +++++ samples/hid/Makefile.target | 75 ++ samples/hid/hid_mouse.bpf.c | 134 +++ samples/hid/hid_mouse.c | 160 ++++ samples/hid/hid_surface_dial.bpf.c | 161 ++++ samples/hid/hid_surface_dial.c | 231 +++++ tools/include/uapi/linux/hid.h | 62 ++ tools/include/uapi/linux/hid_bpf.h | 25 + tools/testing/selftests/Makefile | 1 + tools/testing/selftests/hid/.gitignore | 4 + tools/testing/selftests/hid/Makefile | 242 +++++ tools/testing/selftests/hid/config | 20 + tools/testing/selftests/hid/hid_bpf.c | 846 ++++++++++++++++++ tools/testing/selftests/hid/progs/hid.c | 206 +++++ 34 files changed, 4815 insertions(+), 10 deletions(-) create mode 100644 Documentation/hid/hid-bpf.rst create mode 100644 drivers/hid/bpf/Kconfig create mode 100644 drivers/hid/bpf/Makefile create mode 100644 drivers/hid/bpf/entrypoints/Makefile create mode 100644 drivers/hid/bpf/entrypoints/README create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.bpf.c create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.lskel.h create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.c create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.h create mode 100644 drivers/hid/bpf/hid_bpf_jmp_table.c create mode 100644 include/linux/hid_bpf.h create mode 100644 include/uapi/linux/hid_bpf.h create mode 100644 samples/hid/.gitignore create mode 100644 samples/hid/Makefile create mode 100644 samples/hid/Makefile.target create mode 100644 samples/hid/hid_mouse.bpf.c create mode 100644 samples/hid/hid_mouse.c create mode 100644 samples/hid/hid_surface_dial.bpf.c create mode 100644 samples/hid/hid_surface_dial.c create mode 100644 tools/include/uapi/linux/hid.h create mode 100644 tools/include/uapi/linux/hid_bpf.h create mode 100644 tools/testing/selftests/hid/.gitignore create mode 100644 tools/testing/selftests/hid/Makefile create mode 100644 tools/testing/selftests/hid/config create mode 100644 tools/testing/selftests/hid/hid_bpf.c create mode 100644 tools/testing/selftests/hid/progs/hid.c -- 2.36.1

Since we're using Python 3.7+, we can use dataclasses to tersen the code. It also lets us create pre-populated TestCounts() objects and compare them in our unit test. (Before, you could only create empty ones).

[PATCH RFC v2 0/8] Add KUnit support for i915 driver

by Mauro Carvalho Chehab

This RFC patch series implement KUnit support for i915 driver, using the already-existing tests inside i915 selftests. On this version, mock selftest can now run in qemu with: $ ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kunitconfig=drivers/gpu/drm/i915/selftests The tests which depends on having a real i915 hardware will be skipped. All selftests will run on bare metal, by modprobing test-i915 module. The output can be parsed (with a hack) using kunit.py: $ (echo "[ 0.000000] TAP version 14"; dmesg)>logs; ./tools/testing/kunit/kunit.py parse logs [14:29:06] ============================================================ [14:29:06] ============ i915 mock selftests (18 subtests) ============= [14:29:06] [PASSED] mock_sanitycheck [14:29:06] [PASSED] mock_shmem [14:29:06] [PASSED] mock_fence [14:29:06] [PASSED] mock_scatterlist [14:29:06] [PASSED] mock_syncmap [14:29:06] [PASSED] mock_uncore [14:29:06] [PASSED] mock_ring [14:29:06] [PASSED] mock_engine [14:29:06] [PASSED] mock_timelines [14:29:06] [PASSED] mock_requests [14:29:06] [PASSED] mock_objects [14:29:06] [PASSED] mock_phys [14:29:06] [PASSED] mock_dmabuf [14:29:06] [PASSED] mock_vma [14:29:06] [PASSED] mock_evict [14:29:06] [PASSED] mock_gtt [14:29:06] [PASSED] mock_hugepages [14:29:06] [PASSED] mock_memory_region [14:29:06] =============== [PASSED] i915 mock selftests =============== [14:29:06] ============ i915 live selftests (36 subtests) ============= [14:29:06] [PASSED] live_sanitycheck [14:29:06] [PASSED] live_uncore [14:29:06] [PASSED] live_workarounds [14:29:06] [PASSED] live_gt_engines [14:29:06] [PASSED] live_gt_timelines [14:29:06] [PASSED] live_gt_contexts [14:29:06] [PASSED] live_gt_lrc [14:29:06] [PASSED] live_gt_mocs [14:29:06] [PASSED] live_gt_pm [14:29:06] [PASSED] live_gt_heartbeat [14:29:06] [PASSED] live_requests [14:29:06] [PASSED] live_migrate [14:29:06] [PASSED] live_active [14:29:06] [PASSED] live_objects [14:29:06] i915: Performing live_mman selftests with st_random_seed=0x1e5d7be5 st_timeout=500 [14:29:06] test_i915: Setting dangerous option KUnit live_mman - tainting kernel [14:29:06] test_i915: Running live_mman on 0000:00:02.0 [14:29:06] Test called without an user context!

Ran 58 tests: passed: 57, failed: 1 It is worth noticing that the mmap tests will fail while running via KUnit. The reason is that such tests depend on having an user context allocated at current->mm. While modprobing i915 with selftests enabled allocates it - this is done by Kernel fork() logic), modprobing test-i915 doesn't. So, such tests won't run. We probably need to modify kunit core in order for it to call mm_alloc() internally before starting the tests. Comments? PS.: the current approach is getting only the final results of the selftests. I opted for this strategy as we need to support i915 selftests, as those are used by Intel DRM CI bot. A more intrusive change could be done in the future, in order to export all tests called via SUBTESTS() macro. It also makes sense to add filtering capabilities to the module, as this ends being needed during development phase, where some tests might fail on newer hardware. --- v2: - changes outside KUnit module moved to separate patches; - added support for running live and perf selftests on bare metal; - made the KUnit test logic identical to i915 selftest.

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

by Maxim Levitsky

Recently while trying to fix some unit tests I found a CVE in SVM nested code. In 'shutdown_interception' vmexit handler we call kvm_vcpu_reset. However if running nested and L1 doesn't intercept shutdown, we will still end up running this function and trigger a bug in it. The bug is that this function resets the 'vcpu->arch.hflags' without properly leaving the nested state, which leaves the vCPU in inconsistent state, which later triggers a kernel panic in SVM code. The same bug can likely be triggered by sending INIT via local apic to a vCPU which runs a nested guest. On VMX we are lucky that the issue can't happen because VMX always intercepts triple faults, thus triple fault in L2 will always be redirected to L1. Plus the 'handle_triple_fault' of VMX doesn't reset the vCPU. INIT IPI can't happen on VMX either because INIT events are masked while in VMX mode. First 4 patches in this series address the above issue, and are already posted on the list with title, ('nSVM: fix L0 crash if L2 has shutdown condtion which L1 doesn't intercept') I addressed the review feedback and also added a unit test to hit this issue. In addition to these patches I noticed that KVM doesn't honour SHUTDOWN intercept bit of L1 on SVM, and I included a fix to do so - its only for correctness as a normal hypervisor should always intercept SHUTDOWN. A unit test on the other hand might want to not do so. I also extendted the triple_fault_test selftest to hit this issue. Finaly I found another security issue, I found a way to trigger a kernel non rate limited printk on SVM from the guest, and last patch in the series fixes that. A unit test I posted to kvm-unit-tests project hits this issue, so no selftest was added. Best regards, Maxim Levitsky Maxim Levitsky (9): KVM: x86: nSVM: leave nested mode on vCPU free KVM: x86: nSVM: harden svm_free_nested against freeing vmcb02 while still in use KVM: x86: add kvm_leave_nested KVM: x86: forcibly leave nested mode on vCPU reset KVM: selftests: move idt_entry to header kvm: selftests: add svm nested shutdown test KVM: x86: allow L1 to not intercept triple fault KVM: selftests: add svm part to triple_fault_test KVM: x86: remove exit_int_info warning in svm_handle_exit arch/x86/kvm/svm/nested.c | 12 +++- arch/x86/kvm/svm/svm.c | 10 +-- arch/x86/kvm/vmx/nested.c | 4 +- arch/x86/kvm/x86.c | 29 ++++++-- tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 1 + .../selftests/kvm/include/x86_64/processor.h | 13 ++++ .../selftests/kvm/lib/x86_64/processor.c | 13 ---- .../kvm/x86_64/svm_nested_shutdown_test.c | 71 +++++++++++++++++++ .../kvm/x86_64/triple_fault_event_test.c | 71 ++++++++++++++----- 10 files changed, 174 insertions(+), 51 deletions(-) create mode 100644 tools/testing/selftests/kvm/x86_64/svm_nested_shutdown_test.c -- 2.34.3

[PATCH v4 0/3] Implement IOCTL to get and/or the clear info about PTEs

by Muhammad Usama Anjum

Hello, This patch series implements IOCTL on the pagemap procfs file to get the information about the page table entries (PTEs). The following operations are supported in this ioctl: - Get the information if the pages are soft-dirty, file mapped, present or swapped. - Clear the soft-dirty PTE bit of the pages. - Get and clear the soft-dirty PTE bit of the pages atomically. Soft-dirty PTE bit of the memory pages can be read by using the pagemap procfs file. The soft-dirty PTE bit for the whole memory range of the process can be cleared by writing to the clear_refs file. There are other methods to mimic this information entirely in userspace with poor performance: - The mprotect syscall and SIGSEGV handler for bookkeeping - The userfaultfd syscall with the handler for bookkeeping Some benchmarks can be seen here[1]. This series adds features that weren't present earlier: - There is no atomic get soft-dirty PTE bit status and clear operation possible. - The soft-dirty PTE bit of only a part of memory cannot be cleared. Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The procfs interface is enough for finding the soft-dirty bit status and clearing the soft-dirty bit of all the pages of a process. We have the use case where we need to track the soft-dirty PTE bit for only specific pages on demand. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. This syscall is used by games to keep track of dirty pages to process only the dirty pages. The information related to pages if the page is file mapped, present and swapped is required for the CRIU project[2][3]. The addition of the required mask, any mask, excluded mask and return masks are also required for the CRIU project[2]. The IOCTL returns the addresses of the pages which match the specific masks. The page addresses are returned in struct page_region in a compact form. The max_pages is needed to support a use case where user only wants to get a specific number of pages. So there is no need to find all the pages of interest in the range when max_pages is specified. The IOCTL returns when the maximum number of the pages are found. The max_pages is optional. If max_pages is specified, it must be equal or greater than the vec_size. This restriction is needed to handle worse case when one page_region only contains info of one page and it cannot be compacted. This is needed to emulate the Windows getWriteWatch() syscall. Some non-dirty pages get marked as dirty because of the kernel's internal activity (such as VMA merging as soft-dirty bit difference isn't considered while deciding to merge VMAs). The dirty bit of the pages is stored in the VMA flags and in the per page flags. If any of these two bits are set, the page is considered to be soft dirty. Suppose you have cleared the soft dirty bit of half of VMA which will be done by splitting the VMA and clearing soft dirty bit flag in the half VMA and the pages in it. Now kernel may decide to merge the VMAs again. So the half VMA becomes dirty again. This splitting/merging costs performance. The application receives a lot of pages which aren't dirty in reality but marked as dirty. Performance is lost again here. Also sometimes user doesn't want the newly allocated memory to be marked as dirty. PAGEMAP_NO_REUSED_REGIONS flag solves both the problems. It is used to not depend on the soft dirty flag in the VMA flags. So VMA splitting and merging doesn't happen. It only depends on the soft dirty bit of the individual pages. Thus by using this flag, there may be a scenerio such that the new memory regions which are just created, doesn't look dirty when seen with the IOCTL, but look dirty when seen from procfs. This seems okay as the user of this flag know the implication of using it.

[PATCH v16 0/3] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in Documentation/x86/tdx.rst (added by patch 2/3). Following are the details of the patch set: Patch 1/3 -> Preparatory patch for adding attestation support. Patch 2/3 -> Adds user interface driver to support attestation. Patch 3/3 -> Adds selftest support for TDREPORT feature. Commit log history is maintained in the individual patches. Current overall status of this series is, it has no pending issues and can be considered for the upcoming merge cycle.

[PATCH v2 0/5] mm/memfd: MFD_NOEXEC for memfd_create

by jeffxu＠google.com

From: Jeff Xu <jeffxu(a)chromium.org> Hi, This v2 series MFD_NOEXEC, this series includes: 1> address comments in V1 2> add sysctl (vm.mfd_noexec) to change the default file permissions of memfd_create to be non-executable. Below are cover-level for v1: The default file permissions on a memfd include execute bits, which means that such a memfd can be filled with a executable and passed to the exec() family of functions. This is undesirable on systems where all code is verified and all filesystems are intended to be mounted noexec, since an attacker may be able to use a memfd to load unverified code and execute it. Additionally, execution via memfd is a common way to avoid scrutiny for malicious code, since it allows execution of a program without a file ever appearing on disk. This attack vector is not totally mitigated with this new flag, since the default memfd file permissions must remain executable to avoid breaking existing legitimate uses, but it should be possible to use other security mechanisms to prevent memfd_create calls without MFD_NOEXEC on systems where it is known that executable memfds are not necessary. This patch series adds a new MFD_NOEXEC flag for memfd_create(), which allows creation of non-executable memfds, and as part of the implementation of this new flag, it also adds a new F_SEAL_EXEC seal, which will prevent modification of any of the execute bits of a sealed memfd. I am not sure if this is the best way to implement the desired behavior (for example, the F_SEAL_EXEC seal is really more of an implementation detail and feels a bit clunky to expose), so suggestions are welcome for alternate approaches. v1: https://lwn.net/Articles/890096/ Daniel Verkamp (4): mm/memfd: add F_SEAL_EXEC mm/memfd: add MFD_NOEXEC flag to memfd_create selftests/memfd: add tests for F_SEAL_EXEC selftests/memfd: add tests for MFD_NOEXEC Jeff Xu (1): sysctl: add support for mfd_noexec include/linux/mm.h | 4 + include/uapi/linux/fcntl.h | 1 + include/uapi/linux/memfd.h | 1 + kernel/sysctl.c | 9 ++ mm/memfd.c | 39 ++++- mm/shmem.c | 6 + tools/testing/selftests/memfd/memfd_test.c | 163 ++++++++++++++++++++- 7 files changed, 221 insertions(+), 2 deletions(-) base-commit: 9e2f40233670c70c25e0681cb66d50d1e2742829 -- 2.37.1.559.g78731f0fdb-goog

arm32: kselftest: zram: Unable to handle kernel NULL pointer dereference at virtual address 00000144

by Naresh Kamboju

While running kselftest zram test case on x15 device and qemu-arm on stable-rc 6.0.7-rc1 the following kernel crash noticed the image was built with gcc-10. This is not regression because it has been happening on mainline and next.

[PATCH V5 0/5] Add tbench/gitsource new test cases for amd-pstate-ut

by Meng Li

Hi all: First, rename amd-pstate-ut.sh to basic.sh as a basic test, mainly for AMD P-State kernel drivers. The purpose of this modification is to facilitate the subsequent addition of gitsource, tbench and other tests. Second, split basic.sh into run.sh and basic.sh. The modification makes basic.sh more pure, just for test basic kernel functions. The file of run.sh mainly contains functions such as test entry, parameter check, prerequisite and log clearing etc. Third, add tbench.sh trigger the tbench testing and monitor the cpu. Fourth, add gitsource.sh trigger the gitsource testing and monitor the cpu information. Finally, modify rst document to introduce test steps and results etc. See patch series in below git repo: V1:https://lore.kernel.org/lkml/20220706073622.672135-1-li.meng@amd.com/ V2:https://lore.kernel.org/lkml/20220804054414.1510764-1-li.meng@amd.com/ V3:https://lore.kernel.org/lkml/20220914061105.1982477-1-li.meng@amd.com/ V4:https://lore.kernel.org/lkml/20221024013356.1639489-1-li.meng@amd.com/ Changes from V1->V2: - selftests: amd-pstate: basic - - delete main.sh and merge funtions into run.sh - selftests: amd-pstate: tbench - - modify ppw to performance per watt for tbench. - - add comments for performance per watt for tbench. - - add comparative test on acpi-cpufreq for tbench. - - calculate drop between amd-pstate and acpi-cpufreq etc. - - plot images about perfrmance,energy and ppw for tbench. - selftests: amd-pstate: gitsource - - modify ppw to performance per watt for gitsource. - - add comments for performance per watt for gitsource. - - add comparative test on acpi-cpufreq for gitsource. - - calculate drop between amd-pstate and acpi-cpufreq etc. - - plot images about perfrmance,energy and ppw for gitsource. - Documentation: amd-pstate: - - modify rst doc, introduce comparative test etc. Changes from V2->V3: - selftests: amd-pstate: - - reduce print logs for governor. - - add a check to see if tbench and the perf tools are already installed. - - install tbench package from apt or yum. - - correct spelling errors from comprison to comparison.

[PATCH 0/8] efficiently expose damos action tried regions information

by SeongJae Park

Changes from RFC (https://lore.kernel.org/damon/20221019001317.104270-1-sj@kernel.org/): - Split out cleanup/refactoring parts[1] [1] https://lore.kernel.org/damon/20221026225943.100429-1-sj@kernel.org/ ----------------------------------------------------------------------- DAMON users can retrieve the monitoring results via 'after_aggregation' callbacks if the user is using the kernel API, or 'damon_aggregated' tracepoint if the user is in the user space. Those are useful if full monitoring results are necessary. However, if the user has interest in only a snapshot of the results for some regions having specific access pattern, the interfaces could be inefficient. For example, some users only want to know which memory regions are not accessed for more than a specific time at the moment. Also, some DAMOS users would want to know exactly to what memory regions the schemes' actions tried to be applied, for a debugging or a tuning. As DAMOS has its internal mechanism for quota and regions prioritization, the users would need to simulate DAMOS' mechanism against the monitoring results. That's unnecessarily complex. This patchset implements DAMON kernel API callbacks and sysfs directory for efficient exposure of the information for the use cases. The new callback will be called for each region when a DAMOS action is gonna tried to be applied to it. The sysfs directory will be called 'tried_regions' and placed under each scheme sysfs directory. Users can write a special keyworkd, 'update_schemes_regions', to the 'state' file of a kdamond sysfs directory. Then, DAMON sysfs interface will fill the directory with the information of regions that corresponding scheme action was tried to be applied for next one aggregation interval. Patches Sequence ---------------- The first one (patch 1) implements the callback for the kernel space users. Following two patches (patches 2 and 3) implements sysfs directories for the information and its sub directories. Two patches (patches 4 and 5) for implementing the special keywords for filling the data to and cleaning up the directories follow. Patch 6 adds a selftest for the new sysfs directory. Finally, two patches (patches 7 and 8) document the new feature in the administrator guide and the ABI document. Assembled Tree -------------- This patchset is based on the latest mm-unstable tree[1]. Assembled tree is also available at the damon/next tree[2].

[PATCH RFC] drm/i915: allow running mock selftests via Kunit

by Mauro Carvalho Chehab

The mock selftests don't require any hardware to run. They can easily run via kunit with qemu or bare metal. Add support for it. With this change, mock selftest can now run in qemu with: $ ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kunitconfig=drivers/gpu/drm/i915/selftests [16:50:24] Configuring KUnit Kernel ...

[PATCH 1/2] kunit: tool: make unit test not print parsed testdata to stdout

by Daniel Latypov

Currently, if you run $ ./tools/testing/kunit/kunit_tool_test.py you'll see a lot of output from the parser as we feed it testdata. This makes the output hard to read and fairly confusing, esp. since our testdata includes example failures, which get printed out in red. Silence that output so real failures are easier to see.
