Pull x86 shadow stack support from Dave Hansen: "This is the long awaited x86 shadow stack support, part of Intel's Control-flow Enforcement Technology (CET). CET consists of two related security features: shadow stacks and indirect branch tracking. This series implements just the shadow stack part of this feature, and just for userspace. The main use case for shadow stack is providing protection against return oriented programming attacks. It works by maintaining a secondary (shadow) stack using a special memory type that has protections against modification. When executing a CALL instruction, the processor pushes the return address to both the normal stack and to the special permission shadow stack. Upon RET, the processor pops the shadow stack copy and compares it to the normal stack copy. For more information, refer to the links below for the earlier versions of this patch set" Link: https://lore.kernel.org/lkml/20220130211838.8382-1-rick.p.edgecombe@intel.com/ Link: https://lore.kernel.org/lkml/20230613001108.3040476-1-rick.p.edgecombe@intel.com/ * tag 'x86_shstk_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (47 commits) x86/shstk: Change order of __user in type x86/ibt: Convert IBT selftest to asm x86/shstk: Don't retry vm_munmap() on -EINTR x86/kbuild: Fix Documentation/ reference x86/shstk: Move arch detail comment out of core mm x86/shstk: Add ARCH_SHSTK_STATUS x86/shstk: Add ARCH_SHSTK_UNLOCK x86: Add PTRACE interface for shadow stack selftests/x86: Add shadow stack test x86/cpufeatures: Enable CET CR4 bit for shadow stack x86/shstk: Wire in shadow stack interface x86: Expose thread features in /proc/$PID/status x86/shstk: Support WRSS for userspace x86/shstk: Introduce map_shadow_stack syscall x86/shstk: Check that signal frame is shadow stack mem x86/shstk: Check that SSP is aligned on sigreturn x86/shstk: Handle signals for shadow stack x86/shstk: Introduce routines modifying shstk x86/shstk: Handle thread shadow stack x86/shstk: Add user-mode shadow stack support ...

Pull iommufd updates from Jason Gunthorpe: "On top of the vfio updates is built some new iommufd functionality: - IOMMU_HWPT_ALLOC allows userspace to directly create the low level IO Page table objects and affiliate them with IOAS objects that hold the translation mapping. This is the basic functionality for the normal IOMMU_DOMAIN_PAGING domains. - VFIO_DEVICE_ATTACH_IOMMUFD_PT can be used to replace the current translation. This is wired up to through all the layers down to the driver so the driver has the ability to implement a hitless replacement. This is necessary to fully support guest behaviors when emulating HW (eg guest atomic change of translation) - IOMMU_GET_HW_INFO returns information about the IOMMU driver HW that owns a VFIO device. This includes support for the Intel iommu, and patches have been posted for all the other server IOMMU. Along the way are a number of internal items: - New iommufd kernel APIs: iommufd_ctx_has_group(), iommufd_device_to_ictx(), iommufd_device_to_id(), iommufd_access_detach(), iommufd_ctx_from_fd(), iommufd_device_replace() - iommufd now internally tracks iommu_groups as it needs some per-group data - Reorganize how the internal hwpt allocation flows to have more robust locking - Improve the access interfaces to support detach and replace of an IOAS from an access - New selftests and a rework of how the selftests creates a mock iommu driver to be more like a real iommu driver" Link: https://lore.kernel.org/lkml/ZO%2FTe6LU1ENf58ZW@nvidia.com/ * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: (34 commits) iommufd/selftest: Don't leak the platform device memory when unloading the module iommu/vt-d: Implement hw_info for iommu capability query iommufd/selftest: Add coverage for IOMMU_GET_HW_INFO ioctl iommufd: Add IOMMU_GET_HW_INFO iommu: Add new iommu op to get iommu hardware information iommu: Move dev_iommu_ops() to private header iommufd: Remove iommufd_ref_to_users() iommufd/selftest: Make the mock iommu driver into a real driver vfio: Support IO page table replacement iommufd/selftest: Add IOMMU_TEST_OP_ACCESS_REPLACE_IOAS coverage iommufd: Add iommufd_access_replace() API iommufd: Use iommufd_access_change_ioas in iommufd_access_destroy_object iommufd: Add iommufd_access_change_ioas(_id) helpers iommufd: Allow passing in iopt_access_list_id to iopt_remove_access() vfio: Do not allow !ops->dma_unmap in vfio_pin/unpin_pages() iommufd/selftest: Add a selftest for IOMMU_HWPT_ALLOC iommufd/selftest: Return the real idev id from selftest mock_domain iommufd: Add IOMMU_HWPT_ALLOC iommufd/selftest: Test iommufd_device_replace() iommufd: Make destroy_rwsem use a lock class per object type ...

Pull clk subsystem updates from Stephen Boyd: "This pull request is full of clk driver changes. In fact, there aren't any changes to the clk framework this time around. That's probably because everyone was on vacation (yours truly included). We did lose a couple clk drivers this time around because nobody was using those devices. That skews the diffstat a bit, but either way, nothing looks out of the ordinary here. The usual suspects are chugging along adding support for more SoCs and fixing bugs. If I had to choose, I'd say the theme for the past few months has been "polish". There's quite a few patches that migrate to devm_platform_ioremap_resource() in here. And there's more than a handful of patches that move the NR_CLKS define from the DT binding header to the driver. There's even patches that migrate drivers to use clk_parent_data and clk_hw to describe clk tree topology. It seems that the spring (summer?) cleaning bug got some folks, or the semiconductor shortage finally hit the software side.

Pull devicetree updates from Rob Herring: "DT core: - Add support for generating DT nodes for PCI devices. This is the groundwork for applying overlays to PCI devices containing non-discoverable downstream devices. - DT unittest additions to check reverted changesets, to test for refcount issues, and to test unresolved symbols. Also, various clean-ups of the unittest along the way. - Refactor node and property manipulation functions to better share code with old API and changeset API - Refactor changeset print functions to a common implementation - Move some platform_device specific functions into of_platform.c Bindings: - Treewide fixing of typos - Treewide clean-up of SPDX tags to use 'OR' consistently - Last chunk of dropping unnecessary quotes.

Intel CPUs ship with ERMS for over a decade, but this is not true for AMD. In particular one reasonably recent uarch (EPYC 7R13) does not have it (or at least the bit is inactive when running on the Amazon EC2 cloud -- I found rather conflicting information about AMD CPUs vs the extension). Hand-rolled mov loops executing in this case are quite pessimal compared to rep movsq for bigger sizes. While the upper limit depends on uarch, everyone is well south of 1KB AFAICS and sizes bigger than that are common. While technically ancient CPUs may be suffering from rep usage, gcc has been emitting it for years all over kernel code, so I don't think this is a legitimate concern. Sample result from read1_processes from will-it-scale (4KB reads/s): before: 1507021 after: 1721828 (+14%) Note that the cutoff point for rep usage is set to 64 bytes, which is way too conservative but I'm sticking to what was done in 47ee3f1d ("x86: re-introduce support for ERMS copies for user space accesses"). That is to say *some* copies will now go slower, which is fixable but beyond the scope of this patch.

Pull LSM updates from Paul Moore: - Add proper multi-LSM support for xattrs in the security_inode_init_security() hook Historically the LSM layer has only allowed a single LSM to add an xattr to an inode, with IMA/EVM measuring that and adding its own as well. As we work towards promoting IMA/EVM to a "proper LSM" instead of the special case that it is now, we need to better support the case of multiple LSMs each adding xattrs to an inode and after several attempts we now appear to have something that is working well. It is worth noting that in the process of making this change we uncovered a problem with Smack's SMACK64TRANSMUTE xattr which is also fixed in this pull request. - Additional LSM hook constification Two patches to constify parameters to security_capget() and security_binder_transfer_file(). While I generally don't make a special note of who submitted these patches, these were the work of an Outreachy intern, Khadija Kamran, and that makes me happy; hopefully it does the same for all of you reading this. - LSM hook comment header fixes One patch to add a missing hook comment header, one to fix a minor typo. - Remove an old, unused credential function declaration It wasn't clear to me who should pick this up, but it was trivial, obviously correct, and arguably the LSM layer has a vested interest in credentials so I merged it.
