[RFC net-next 0/7] selftests: net: Switch pmtu.sh to use the internal ovs script.

by Aaron Conole

Currently, if a user wants to run pmtu.sh and cover all the provided test cases, they need to install the Open vSwitch userspace utilities. This dependency is difficult for users as well as CI environments, because the userspace build and setup may require lots of support and devel packages to be installed, system setup to be correct, and things like permissions and selinux policies to be properly configured. The kernel selftest suite includes an ovs-dpctl.py utility which can interact with the openvswitch module directly. This lets developers and CI environments run without needing too many extra dependencies - just the pyroute2 python package. This series enhances the ovs-dpctl utility to provide support for set() and tunnel() flow specifiers, better ipv6 handling support, and the ability to add tunnel vports, and LWT interfaces. Finally, it modifies the pmtu.sh script to call the ovs-dpctl.py utility rather than the typical OVS userspace utilities. NOTE: This could also be applied as-is. I'm trying to get the vng test working in my environment, so I submitted as RFC because I didn't get to test with the config change in 7/7. Aaron Conole (6): selftests: openvswitch: Support explicit tunnel port creation. selftests: openvswitch: Refactor actions parsing. selftests: openvswitch: Add set() and set_masked() support. selftests: openvswitch: Add support for tunnel() key. selftests: openvswitch: Support implicit ipv6 arguments. selftests: net: Use the provided dpctl rather than the vswitchd for tests. selftests: net: add config for openvswitch .../selftests/net/openvswitch/ovs-dpctl.py | 370 +++++++++++++++--- tools/testing/selftests/net/config | 5 ++++ tools/testing/selftests/net/pmtu.sh | 87 +++- 3 files changed, 394 insertions(+), 68 deletions(-) -- 2.45.1

[PATCH v2 0/3] Userspace controls soft-offline pages

by Jiaqi Yan

Correctable memory errors are very common on servers with large amount of memory, and are corrected by ECC, but with two pain points to users: 1. Correction usually happens on the fly and adds latency overhead 2. Not-fully-proved theory states excessive correctable memory errors can develop into uncorrectable memory error. Soft offline is kernel's additional solution for memory pages having (excessive) corrected memory errors. Impacted page is migrated to healthy page if it is in use, then the original page is discarded for any future use. The actual policy on whether (and when) to soft offline should be maintained by userspace, especially in case of an 1G HugeTLB page. Soft-offline dissolves the HugeTLB page, either in-use or free, into chunks of 4K pages, reducing HugeTLB pool capacity by 1 hugepage. If userspace has not acknowledged such behavior, it may be surprised when later mmap hugepages MAP_FAILED due to lack of hugepages. In case of a transparent hugepage, it will be split into 4K pages as well; userspace will stop enjoying the transparent performance. In addition, discarding the entire 1G HugeTLB page only because of corrected memory errors sounds very costly and kernel better not doing under the hood. But today there are at least 2 such cases: 1. GHES driver sees both GHES_SEV_CORRECTED and CPER_SEC_ERROR_THRESHOLD_EXCEEDED after parsing CPER. 2. RAS Correctable Errors Collector counts correctable errors per PFN and when the counter for a PFN reaches threshold In both cases, userspace has no control of the soft offline performed by kernel's memory failure recovery. This patch series give userspace the control of softofflining any page: kernel only soft offlines raw page / transparent hugepage / HugeTLB hugepage if userspace has agreed to. The interface to userspace is a new sysctl called enable_soft_offline under /proc/sys/vm. By default enable_soft_line is 1 to preserve existing behavior in kernel. Changelog v1 => v2: * incorporate feedbacks from both Miaohe Lin <linmiaohe(a)huawei.com> and Jane Chu <jane.chu(a)oracle.com>. * make the switch to control all pages, instead of HugeTLB specific. * change the API from /sys/kernel/mm/hugepages/hugepages-${size}kB/softoffline_corrected_errors to /proc/sys/vm/enable_soft_offline. * minor update to test code. * update documentation of the user control API. * v2 is based on commit 83a7eefedc9b ("Linux 6.10-rc3").

[RFC PATCH v1 0/2] KVM: arm64: Making BT Field in ID_AA64PFR1_EL1 writable

by Shaoqin Huang

Hi guys, I'm trying to enable migration from MtCollins(Ampere Altra, ARMv8.2+) to AmpereOne(AmpereOne, ARMv8.6+), the migration always fails when migration from MtCollins to AmpereOne due to some register fields differing between the two machines. In this patch series, we try to make more register fields writable like ID_AA64PFR1_EL1.BT. This is first step towards making the migration possible. Some other hurdles need to be overcome. This is not sufficient to make the migration successful from MtCollins to AmpereOne.

[PATCH] selftests/mm:fix test_prctl_fork_exec return failure

by aigourensheng

after calling fork() in the test_prctl_fork_exec() function, the global variable ksm_full_scans_fd is initialized to 0 in the child process upon entering the main function of ./ksm_functional_tests. In the function call chain test_child_ksm() -> __mmap_and_merge_range -> ksm_merge-> ksm_get_full_scans, start_scans = ksm_get_full_scans() will return an error. Therefore, the value of ksm_full_scans_fd needs to be initialized before calling test_child_ksm in the child process.

[PATCH] kselftest/alsa: Fix validation of writes to volatile controls

by Mark Brown

When validating writes to controls we check that whatever value we wrote actually appears in the control. For volatile controls we cannot assume that this will be the case, the value may be changed at any time including between our write and read. Handle this by moving the check for volatile controls that we currently do for events to a separate block and just verifying that whatever value we read is valid for the control.

[PATCH net-next 0/6] selftests: mptcp: use net/lib.sh to manage netns

by Matthieu Baerts (NGI0)

The goal of this series is to use helpers from net/lib.sh with MPTCP selftests. - Patches 1 to 4 are some clean-ups and preparation in net/lib.sh: - Patch 1 simplifies the code handling errexit by ignoring possible errors instead of disabling errexit temporary. - Patch 2 removes the netns from the list after having cleaned it, not to try to clean it twice. - Patch 3 removes the 'readonly' attribute for the netns variable, to allow using the same name in local variables. - Patch 4 removes the local 'ns' var, not to conflict with the global one it needs to setup. - Patch 5 uses helpers from net/lib.sh to create and delete netns in MPTCP selftests. - Patch 6 uses wait_local_port_listen helper from net/net_helper.sh.

[PATCH v2] selftests/vDSO: fix clang build errors and warnings

by John Hubbard

When building with clang, via: make LLVM=1 -C tools/testing/selftests ...there are several warnings, and an error. This fixes all of those and allows these tests to run and pass. 1. Fix linker error (undefined reference to memcpy) by providing a local version of memcpy. 2. clang complains about using this form: if (g = h & 0xf0000000) ...so factor out the assignment into a separate step. 3. The code is passing a signed const char* to elf_hash(), which expects a const unsigned char *. There are several callers, so fix this at the source by allowing the function to accept a signed argument, and then converting to unsigned operations, once inside the function. 4. clang doesn't have __attribute__((externally_visible)) and generates a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem to require that attribute in order to build, run and pass tests here, so remove it.

[PATCH net-next 1/2] selftests: openvswitch: fix action formatting

by Adrian Moreno

In the action formatting function ("dpstr"), the iteration is made over the nla_map, so if there are more than one attribute from the same type we only print the first one.

[PATCH 0/5] ALSA: some driver fixes for control input validations

by Takashi Iwai

Hi, this is a patch set as a follow up of the thread about the errors reported by kselftest mixer-test. It changes HD-audio and vmaster control behavior to return -EINVAL for invalid input values. There is a change in kselftest itself to skip the write tests for volatile controls, too. It's for the channel map controls that can't hold the stable values.

[PATCH] tools/testing/selftests/livepatch: define max test-syscall processes

[PATCH 0/5] cleanups, fixes, and progress towards avoiding "make headers"

by John Hubbard

Eventually, once the build succeeds on a sufficiently old distro, the idea is to delete $(KHDR_INCLUDES) from the selftests/mm build, and then after that, from selftests/lib.mk and all of the other selftest builds. For now, this series merely achieves a clean build of selftests/mm on a not-so-old distro: Ubuntu 23.04: 1. Add __NR_mseal. 2. Add fs.h, taken as usual from a snapshot of ./usr/include/linux/fs.h after running "make headers". This is how we have agreed to do this sort of thing, see [1]. 3. Add a few selected prctl.h values that the ksm and mdwe tests require.

[PATCH HID v3 00/16] HID: convert HID-BPF into using bpf_struct_ops

by Benjamin Tissoires

The purpose of this series is to rethink how HID-BPF is invoked. Currently it implies a jmp table, a prog fd bpf_map, a preloaded tracing bpf program and a lot of manual work for handling the bpf program lifetime and addition/removal. OTOH, bpf_struct_ops take care of most of the bpf handling leaving us with a simple list of ops pointers, and we can directly call the struct_ops program from the kernel as a regular function. The net gain right now is in term of code simplicity and lines of code removal (though is an API breakage), but udev-hid-bpf is able to handle such breakages. In the near future, we will be able to extend the HID-BPF struct_ops with entrypoints for hid_hw_raw_request() and hid_hw_output_report(), allowing for covering all of the initial use cases: - firewalling a HID device - fixing all of the HID device interactions (not just device events as it is right now). The matching user-space loader (udev-hid-bpf) MR is at https://gitlab.freedesktop.org/libevdev/udev-hid-bpf/-/merge_requests/86 I'll put it out of draft once this is merged.

[PATCH v15 9/9] selftests/udmabuf: Add tests to verify data after page migration

by Vivek Kasireddy

Since the memfd pages associated with a udmabuf may be migrated as part of udmabuf create, we need to verify the data coherency after successful migration. The new tests added in this patch try to do just that using 4k sized pages and also 2 MB sized huge pages for the memfd. Successful completion of the tests would mean that there is no disconnect between the memfd pages and the ones associated with a udmabuf. And, these tests can also be augmented in the future to test newer udmabuf features (such as handling memfd hole punch). The idea for these tests comes from a patch by Mike Kravetz here: https://lists.freedesktop.org/archives/dri-devel/2023-June/410623.html v1->v2: (suggestions from Shuah) - Use ksft_* functions to print and capture results of tests - Use appropriate KSFT_* status codes for exit() - Add Mike Kravetz's suggested-by tag Cc: Shuah Khan <shuah(a)kernel.org> Cc: David Hildenbrand <david(a)redhat.com> Cc: Daniel Vetter <daniel.vetter(a)ffwll.ch> Cc: Hugh Dickins <hughd(a)google.com> Cc: Peter Xu <peterx(a)redhat.com> Cc: Jason Gunthorpe <jgg(a)nvidia.com> Cc: Gerd Hoffmann <kraxel(a)redhat.com> Cc: Dongwon Kim <dongwon.kim(a)intel.com> Cc: Junxiao Chang <junxiao.chang(a)intel.com> Cc: linux-kselftest(a)vger.kernel.org Suggested-by: Mike Kravetz <mike.kravetz(a)oracle.com> Acked-by: Dave Airlie <airlied(a)redhat.com> Acked-by: Gerd Hoffmann <kraxel(a)redhat.com> Signed-off-by: Vivek Kasireddy <vivek.kasireddy(a)intel.com> --- .../selftests/drivers/dma-buf/udmabuf.c | 214 +++++++++++++++--- 1 file changed, 183 insertions(+), 31 deletions(-) diff --git a/tools/testing/selftests/drivers/dma-buf/udmabuf.c b/tools/testing/selftests/drivers/dma-buf/udmabuf.c index c812080e304e..6062723a172e 100644 --- a/tools/testing/selftests/drivers/dma-buf/udmabuf.c +++ b/tools/testing/selftests/drivers/dma-buf/udmabuf.c @@ -9,52 +9,162 @@ #include <errno.h> #include <fcntl.h> #include <malloc.h> +#include <stdbool.h> #include <sys/ioctl.h> #include <sys/syscall.h> +#include <sys/mman.h> #include <linux/memfd.h> #include <linux/udmabuf.h> +#include "../../kselftest.h" #define TEST_PREFIX "drivers/dma-buf/udmabuf" #define NUM_PAGES 4 +#define NUM_ENTRIES 4 +#define MEMFD_SIZE 1024 /* in pages */ -static int memfd_create(const char *name, unsigned int flags) +static unsigned int page_size;

[PATCH 0/2] kselftest: devices: Allow running test on more platforms

by Nícolas F. R. A. Prado

This series adds two new features required to be able to run the test on more platforms on KernelCI. The first patch adds a parameter to allow overriding the directory in which the board files will be looked for. Since the board files are hosted in a separate repository [1], this parameter allows overlaying those files on the filesystem and passing the location to the test. The second is needed for one platform in particular, MT8195, in which the usb controllers are instanced from a two-level deep DT node that doesn't allow unique matching based on the existing properties.

[PATCH v2 00/13] riscv: Add support for xtheadvector

by Charlie Jenkins

xtheadvector is a custom extension that is based upon riscv vector version 0.7.1 [1]. All of the vector routines have been modified to support this alternative vector version based upon whether xtheadvector was determined to be supported at boot. vlenb is not supported on the existing xtheadvector hardware, so a devicetree property thead,vlenb is added to provide the vlenb to Linux. There is a new hwprobe key RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0 that is used to request which thead vendor extensions are supported on the current platform. This allows future vendors to allocate hwprobe keys for their vendor. Support for xtheadvector is also added to the vector kselftests. Signed-off-by: Charlie Jenkins <charlie(a)rivosinc.com> [1] https://github.com/T-head-Semi/thead-extension-spec/blob/95358cb2cca9489361… --- This series is a continuation of a different series that was fragmented into two other series in an attempt to get part of it merged in the 6.10 merge window. The split-off series did not get merged due to a NAK on the series that added the generic riscv,vlenb devicetree entry. This series has converted riscv,vlenb to thead,vlenb to remedy this issue. The original series is titled "riscv: Support vendor extensions and xtheadvector" [3]. The series titled "riscv: Extend cpufeature.c to detect vendor extensions" is still under development and this series is based on that series! [4] I have tested this with an Allwinner Nezha board. I ran into issues booting the board after 6.9-rc1 so I applied these patches to 6.8. There are a couple of minor merge conflicts that do arrise when doing that, so please let me know if you have been able to boot this board with a 6.9 kernel. I used SkiffOS [1] to manage building the image, but upgraded the U-Boot version to Samuel Holland's more up-to-date version [2] and changed out the device tree used by U-Boot with the device trees that are present in upstream linux and this series. Thank you Samuel for all of the work you did to make this task possible.
