[PATCH v7 00/19] Add iommufd physical device operations for replace and alloc hwpt

by Jason Gunthorpe

This is the basic functionality for iommufd to support iommufd_device_replace() and IOMMU_HWPT_ALLOC for physical devices. iommufd_device_replace() allows changing the HWPT associated with the device to a new IOAS or HWPT. Replace does this in way that failure leaves things unchanged, and utilizes the iommu iommu_group_replace_domain() API to allow the iommu driver to perform an optional non-disruptive change. IOMMU_HWPT_ALLOC allows HWPTs to be explicitly allocated by the user and used by attach or replace. At this point it isn't very useful since the HWPT is the same as the automatically managed HWPT from the IOAS. However a following series will allow userspace to customize the created HWPT. The implementation is complicated because we have to introduce some per-iommu_group memory in iommufd and redo how we think about multi-device groups to be more explicit. This solves all the locking problems in the prior attempts. This series is infrastructure work for the following series which: - Add replace for attach - Expose replace through VFIO APIs - Implement driver parameters for HWPT creation (nesting) Once review of this is complete I will keep it on a side branch and accumulate the following series when they are ready so we can have a stable base and make more incremental progress. When we have all the parts together to get a full implementation it can go to Linus. This is on github: https://github.com/jgunthorpe/linux/commits/iommufd_hwpt v7: - Rebase to v6.4-rc2, update to new signature of iommufd_get_ioas() v6: https://lore.kernel.org/r/0-v6-fdb604df649a+369-iommufd_alloc_jgg@nvidia.com - Go back to the v4 locking arragnment with now both the attach/detach igroup->locks inside the functions, Kevin says he needs this for a followup series. This still fixes the syzkaller bug - Fix two more error unwind locking bugs where iommufd_object_abort_and_destroy(hwpt) would deadlock or be mislocked. Make sure fail_nth will catch these mistakes - Add a patch allowing objects to have different abort than destroy function, it allows hwpt abort to require the caller to continue to hold the lock and enforces this with lockdep. v5: https://lore.kernel.org/r/0-v5-6716da355392+c5-iommufd_alloc_jgg@nvidia.com - Go back to the v3 version of the code, keep the comment changes from v4. Syzkaller says the group lock change in v4 didn't work. - Adjust the fail_nth test to cover the path syzkaller found. We need to have an ioas with a mapped page installed to inject a failure during domain attachment. v4: https://lore.kernel.org/r/0-v4-9cd79ad52ee8+13f5-iommufd_alloc_jgg@nvidia.c… - Refine comments and commit messages - Move the group lock into iommufd_hw_pagetable_attach() - Fix error unwind in iommufd_device_do_replace() v3: https://lore.kernel.org/r/0-v3-61d41fd9e13e+1f5-iommufd_alloc_jgg@nvidia.com - Refine comments and commit messages - Adjust the flow in iommufd_device_auto_get_domain() so pt_id is only set on success - Reject replace on non-attached devices - Add missing __reserved check for IOMMU_HWPT_ALLOC v2: https://lore.kernel.org/r/0-v2-51b9896e7862+8a8c-iommufd_alloc_jgg@nvidia.c… - Use WARN_ON for the igroup->group test and move that logic to a function iommufd_group_try_get() - Change igroup->devices to igroup->device list Replace will need to iterate over all attached idevs - Rename to iommufd_group_setup_msi() - New patch to export iommu_get_resv_regions() - New patch to use per-device reserved regions instead of per-group regions - Split out the reorganizing of iommufd_device_change_pt() from the replace patch - Replace uses the per-dev reserved regions - Use stdev_id in a few more places in the selftest - Fix error handling in IOMMU_HWPT_ALLOC - Clarify comments - Rebase on v6.3-rc1 v1: https://lore.kernel.org/all/0-v1-7612f88c19f5+2f21-iommufd_alloc_jgg@nvidia… Jason Gunthorpe (17): iommufd: Move isolated msi enforcement to iommufd_device_bind() iommufd: Add iommufd_group iommufd: Replace the hwpt->devices list with iommufd_group iommu: Export iommu_get_resv_regions() iommufd: Keep track of each device's reserved regions instead of groups iommufd: Use the iommufd_group to avoid duplicate MSI setup iommufd: Make sw_msi_start a group global iommufd: Move putting a hwpt to a helper function iommufd: Add enforced_cache_coherency to iommufd_hw_pagetable_alloc() iommufd: Allow a hwpt to be aborted after allocation iommufd: Fix locking around hwpt allocation iommufd: Reorganize iommufd_device_attach into iommufd_device_change_pt iommufd: Add iommufd_device_replace() iommufd: Make destroy_rwsem use a lock class per object type iommufd: Add IOMMU_HWPT_ALLOC iommufd/selftest: Return the real idev id from selftest mock_domain iommufd/selftest: Add a selftest for IOMMU_HWPT_ALLOC Nicolin Chen (2): iommu: Introduce a new iommu_group_replace_domain() API iommufd/selftest: Test iommufd_device_replace() drivers/iommu/iommu-priv.h | 10 + drivers/iommu/iommu.c | 41 +- drivers/iommu/iommufd/device.c | 553 +++++++++++++----- drivers/iommu/iommufd/hw_pagetable.c | 112 +++- drivers/iommu/iommufd/io_pagetable.c | 32 +- drivers/iommu/iommufd/iommufd_private.h | 52 +- drivers/iommu/iommufd/iommufd_test.h | 6 + drivers/iommu/iommufd/main.c | 24 +- drivers/iommu/iommufd/selftest.c | 40 ++ include/linux/iommufd.h | 1 + include/uapi/linux/iommufd.h | 26 + tools/testing/selftests/iommu/iommufd.c | 67 ++- .../selftests/iommu/iommufd_fail_nth.c | 67 ++- tools/testing/selftests/iommu/iommufd_utils.h | 63 +- 14 files changed, 868 insertions(+), 226 deletions(-) create mode 100644 drivers/iommu/iommu-priv.h base-commit: f1fcbaa18b28dec10281551dfe6ed3a3ed80e3d6 -- 2.40.1

[PATCH v4 00/18] selftests/nolibc: allow run with minimal kernel config

by Zhangjin Wu

Hi, Willy This v4 mainly uses the argv0 suggested by you, at the same time, a new run-libc-test target is added for glibc and musl, and the RB_ flags are added for nolibc to allow compile nolibc-test.c without <linux/reboot.h> for glibc, musl and nolibc (mainly for musl-gcc, without -I /path/to/sysroot). This patchset is based on the 20230705-nolibc-series2 branch of nolibc repo [2], it must be applied after our v6 __sysret series [3] (argv0 exported there) and Thomas' chmod_net removal patchset [4] (the new chmod_argv0 is added at the same line of chmod_net, will conflict). This patchset assumes the chmod_net removal patchset will be applied at first, if not, the chmod_argv0 added alphabetically will not be applied. Since our new chmod_argv0 is exactly added to replace chmod_net, so, Willy, is it ok for you to at least apply the chmod_net removal patch [5] before this patchset? selftests/nolibc: drop test chmod_net This patchset is tested together with the v6 __sysret series [3]: arch/board | result ------------|------------ arm/vexpress-a9 | 142 test(s) passed, 1 skipped, 0 failed. arm/virt | 142 test(s) passed, 1 skipped, 0 failed. aarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. ppc/g3beige | not supported ppc/ppce500 | not supported i386/pc | 142 test(s) passed, 1 skipped, 0 failed. x86_64/pc | 142 test(s) passed, 1 skipped, 0 failed. mipsel/malta | 142 test(s) passed, 1 skipped, 0 failed. loongarch64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv64/virt | 142 test(s) passed, 1 skipped, 0 failed. riscv32/virt | 0 test(s) passed, 0 skipped, 0 failed. s390x/s390-ccw-virtio | 142 test(s) passed, 1 skipped, 0 failed.

[PATCH] selftests: hid: fix vmtests.sh not running make headers

by Benjamin Tissoires

According to commit 01d6c48a828b ("Documentation: kselftest: "make headers" is a prerequisite"), running the kselftests requires to run "make headers" first. Do that in "vmtest.sh" as well to fix the HID CI. Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Looks like the new master branch (v6.5-rc1) broke my CI. And given that `make headers` is now a requisite to run the kselftests, also include that command in vmtests.sh. Broken CI job: https://gitlab.freedesktop.org/bentiss/hid/-/jobs/44704436 Fixed CI job: https://gitlab.freedesktop.org/bentiss/hid/-/jobs/45151040 --- tools/testing/selftests/hid/vmtest.sh | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/testing/selftests/hid/vmtest.sh b/tools/testing/selftests/hid/vmtest.sh index 681b906b4853..4da48bf6b328 100755 --- a/tools/testing/selftests/hid/vmtest.sh +++ b/tools/testing/selftests/hid/vmtest.sh @@ -79,6 +79,7 @@ recompile_kernel() cd "${kernel_checkout}" ${make_command} olddefconfig + ${make_command} headers ${make_command} } --- base-commit: 0e382fa72bbf0610be40af9af9b03b0cd149df82 change-id: 20230709-fix-selftests-c8b0bdff1d20 Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>

[PATCH v1 0/5] selftests/nolibc: report: print test status

by Zhangjin Wu

Hi, Willy As you suggested, the 'status: [success|warning|failure]' info is added to the summary line, with additional newlines around this line to extrude the status info. at the same time, the total tests is printed, the passed, skipped and failed values are aligned with '%03d'. This patchset is based on 20230705-nolibc-series2 of nolibc repo[1]. The test result looks like: ... 138 test(s): 135 passed, 002 skipped, 001 failed => status: failure See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/run.out Or: ... 137 test(s): 134 passed, 003 skipped, 000 failed => status: warning See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/run.out Best regards, Zhangjin --- [1]: https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git Zhangjin Wu (5): selftests/nolibc: report: print a summarized test status selftests/nolibc: report: print total tests selftests/nolibc: report: align passed, skipped and failed selftests/nolibc: report: extrude the test status line selftests/nolibc: report: add newline before test failures tools/testing/selftests/nolibc/Makefile | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) -- 2.25.1

It's also documentation. The two are related, as one is the hand off to the other. It's not a random union, and I'd like to leave it that way. -- Steve
