[PATCH 0/2] tools/nolibc: fork: fix on s390 and add test

by Thomas Weißschuh

The generic fork() implementation in nolibc falls back to the clone() syscall. On s390 the first two arguments to clone() are swapped compared to other architectures, breaking the implementation in nolibc. Add a custom implementation of fork() to s390 that works. While at it also add a testcase for fork().

[PATCH v7 0/4] Add IO page table replacement support

by Nicolin Chen

[ This series depends on the VFIO device cdev series ] Changelog v7: * Rebased on top of v6.4-rc1 and cdev v11 candidate * Fixed a wrong file in replace() API patch * Added Kevin's "Reviewed-by" to replace() API patch v6: https://lore.kernel.org/all/cover.1679939952.git.nicolinc@nvidia.com/ * Rebased on top of cdev v8 series https://lore.kernel.org/kvm/20230327094047.47215-1-yi.l.liu@intel.com/ * Added "Reviewed-by" from Kevin to PATCH-4 * Squashed access->ioas updating lines into iommufd_access_change_pt(), and changed function return type accordingly for simplification. v5: https://lore.kernel.org/all/cover.1679559476.git.nicolinc@nvidia.com/ * Kept the cmd->id in the iommufd_test_create_access() so the access can be created with an ioas by default. Then, renamed the previous ioctl IOMMU_TEST_OP_ACCESS_SET_IOAS to IOMMU_TEST_OP_ACCESS_REPLACE_IOAS, so it would be used to replace an access->ioas pointer. * Added iommufd_access_replace() API after the introductions of the other two APIs iommufd_access_attach() and iommufd_access_detach(). * Since vdev->iommufd_attached is also set in emulated pathway too, call iommufd_access_update(), similar to the physical pathway. v4: https://lore.kernel.org/all/cover.1678284812.git.nicolinc@nvidia.com/ * Rebased on top of Jason's series adding replace() and hwpt_alloc() https://lore.kernel.org/all/0-v2-51b9896e7862+8a8c-iommufd_alloc_jgg@nvidia… * Rebased on top of cdev series v6 https://lore.kernel.org/kvm/20230308132903.465159-1-yi.l.liu@intel.com/ * Dropped the patch that's moved to cdev series. * Added unmap function pointer sanity before calling it. * Added "Reviewed-by" from Kevin and Yi. * Added back the VFIO change updating the ATTACH uAPI. v3: https://lore.kernel.org/all/cover.1677288789.git.nicolinc@nvidia.com/ * Rebased on top of Jason's iommufd_hwpt branch: https://lore.kernel.org/all/0-v2-406f7ac07936+6a-iommufd_hwpt_jgg@nvidia.co… * Dropped patches from this series accordingly. There were a couple of VFIO patches that will be submitted after the VFIO cdev series. Also, renamed the series to be "emulated". * Moved dma_unmap sanity patch to the first in the series. * Moved dma_unmap sanity to cover both VFIO and IOMMUFD pathways. * Added Kevin's "Reviewed-by" to two of the patches. * Fixed a NULL pointer bug in vfio_iommufd_emulated_bind(). * Moved unmap() call to the common place in iommufd_access_set_ioas(). v2: https://lore.kernel.org/all/cover.1675802050.git.nicolinc@nvidia.com/ * Rebased on top of vfio_device cdev v2 series. * Update the kdoc and commit message of iommu_group_replace_domain(). * Dropped revert-to-core-domain part in iommu_group_replace_domain(). * Dropped !ops->dma_unmap check in vfio_iommufd_emulated_attach_ioas(). * Added missing rc value in vfio_iommufd_emulated_attach_ioas() from the iommufd_access_set_ioas() call. * Added a new patch in vfio_main to deny vfio_pin/unpin_pages() calls if vdev->ops->dma_unmap is not implemented. * Added a __iommmufd_device_detach helper and let the replace routine do a partial detach(). * Added restriction on auto_domains to use the replace feature. * Added the patch "iommufd/device: Make hwpt_list list_add/del symmetric" from the has_group removal series. v1: https://lore.kernel.org/all/cover.1675320212.git.nicolinc@nvidia.com/ Hi all, The existing IOMMU APIs provide a pair of functions: iommu_attach_group() for callers to attach a device from the default_domain (NULL if not being supported) to a given iommu domain, and iommu_detach_group() for callers to detach a device from a given domain to the default_domain. Internally, the detach_dev op is deprecated for the newer drivers with default_domain. This means that those drivers likely can switch an attaching domain to another one, without stagging the device at a blocking or default domain, for use cases such as: 1) vPASID mode, when a guest wants to replace a single pasid (PASID=0) table with a larger table (PASID=N) 2) Nesting mode, when switching the attaching device from an S2 domain to an S1 domain, or when switching between relevant S1 domains. This series is rebased on top of Jason Gunthorpe's series that introduces iommu_group_replace_domain API and IOMMUFD infrastructure for the IOMMUFD "physical" devices. The IOMMUFD "emulated" deivces will need some extra steps to replace the access->ioas object and its iopt pointer. You can also find this series on Github: https://github.com/nicolinc/iommufd/commits/iommu_group_replace_domain-v7 Thank you Nicolin Chen Nicolin Chen (4): vfio: Do not allow !ops->dma_unmap in vfio_pin/unpin_pages() iommufd: Add iommufd_access_replace() API iommufd/selftest: Add IOMMU_TEST_OP_ACCESS_REPLACE_IOAS coverage vfio: Support IO page table replacement drivers/iommu/iommufd/device.c | 53 ++++++++++++++----- drivers/iommu/iommufd/iommufd_test.h | 4 ++ drivers/iommu/iommufd/selftest.c | 19 +++++++ drivers/vfio/iommufd.c | 11 ++-- drivers/vfio/vfio_main.c | 4 ++ include/linux/iommufd.h | 1 + include/uapi/linux/vfio.h | 6 +++ tools/testing/selftests/iommu/iommufd.c | 29 +++++++++- tools/testing/selftests/iommu/iommufd_utils.h | 19 +++++++ 9 files changed, 127 insertions(+), 19 deletions(-) -- 2.40.1

[PATCH] kselftest: vDSO: Fix accumulation of uninitialized ret when CLOCK_REALTIME is undefined

by Colin Ian King

In the unlikely case that CLOCK_REALTIME is not defined, variable ret is not initialized and further accumulation of return values to ret can leave ret in an undefined state. Fix this by initialized ret to zero and changing the assignment of ret to an accumulation for the CLOCK_REALTIME case.

[PATCH v2] tools/nolibc: Fix build of stdio.h due to header ordering

by Mark Brown

When we added fd based file streams we created references to STx_FILENO in stdio.h but these constants are declared in unistd.h which is the last file included by the top level nolibc.h meaning those constants are not defined when we try to build stdio.h. This causes programs using nolibc.h to fail to build. Reorder the headers to avoid this issue.
