Subject: [GIT PULL] Please pull IOMMUFD subsystem changes From: Jason Gunthorpe To: Linus Torvalds Cc: iommu@lists.linux.dev, kvm@vger.kernel.org, linux-kernel@vger.kernel.org, Kevin Tian Date: Mon, 23 Sep 2024 14:45:35 -0300 --tuLoZ1SXOKftaOK1 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi Linus, Nothing big this time, I was hoping viommu would make it, but not yet. There is a small merge conflict "take mine" to resolve, the mm tree added a debugfs.h include to a file that mine already has. The tag for-linus-iommufd-merged with my merge resolution to your tree is also available to pull.

This updates the nesting parent's IOAS with the reserved regions of the device and will also install the ITS doorbell page on ARM. - Add missed validation of parent domain ops against the current iommu - Fix a syzkaller bug related to integer overflow during ALIGN() - Tidy two iommu_domain attach paths ---------------------------------------------------------------- Jason Gunthorpe (4): iommufd/selftest: Fix buffer read overrrun in the dirty test Merge branch 'nesting_reserved_regions' into iommufd.git for-next iommufd: Check the domain owner of the parent before creating a nesting domain iommufd: Protect against overflow of ALIGN() during iova allocation Nicolin Chen (3): iommufd: Reorder include files iommufd/device: Enforce reserved IOVA also when attached to hwpt_nested iommufd: Reorder struct forward declarations Yi Liu (2): iommufd: Avoid duplicated __iommu_group_set_core_domain() call iommu: Set iommu_attach_handle->domain in core drivers/iommu/iommu.c | 1 + drivers/iommu/iommufd/device.c | 56 ++++++++++++++++----------------- drivers/iommu/iommufd/fault.c | 5 ++- drivers/iommu/iommufd/hw_pagetable.c | 3 +- drivers/iommu/iommufd/io_pagetable.c | 16 +++++++--- drivers/iommu/iommufd/io_pagetable.h | 2 +- drivers/iommu/iommufd/ioas.c | 2 +- drivers/iommu/iommufd/iommufd_private.h | 32 ++++++++++++++++--- drivers/iommu/iommufd/iommufd_test.h | 2 +- drivers/iommu/iommufd/iova_bitmap.c | 2 +- drivers/iommu/iommufd/main.c | 8 ++--- drivers/iommu/iommufd/pages.c | 10 +++--- drivers/iommu/iommufd/selftest.c | 19 ++++++----- include/linux/iommufd.h | 12 +++---- include/uapi/linux/iommufd.h | 2 +- 15 files changed, 101 insertions(+), 71 deletions(-) (diffstat from tag for-linus-iommufd-merged) --tuLoZ1SXOKftaOK1 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQRRRCHOFoQz/8F5bUaFwuHvBreFYQUCZvGpPQAKCRCFwuHvBreF YT40AQDAYrybnBfy8Y+K26+xqUc1f/TEe7zF/gn2ZqUR/7GAdgEAzAAl0WJWfnxi gBpdiNjHwTNbSJtu8vkj7/0W2DMZ1Qo= =dQ9d -----END PGP SIGNATURE----- --tuLoZ1SXOKftaOK1-- .
