[PATCH -next] selftests: Add color to keywords of results report

by Zhao Gongyi

For ksft_test_result_*()/ksft_exit_*(), we could add color to some keywords like: function color *pass* green *fail* red *skip* yellow *error* magenta And it is hoped to improve the readability of the output.

[PATCH v4 0/3] Implement IOCTL to get and/or the clear info about PTEs

by Muhammad Usama Anjum

Hello, This patch series implements IOCTL on the pagemap procfs file to get the information about the page table entries (PTEs). The following operations are supported in this ioctl: - Get the information if the pages are soft-dirty, file mapped, present or swapped. - Clear the soft-dirty PTE bit of the pages. - Get and clear the soft-dirty PTE bit of the pages atomically. Soft-dirty PTE bit of the memory pages can be read by using the pagemap procfs file. The soft-dirty PTE bit for the whole memory range of the process can be cleared by writing to the clear_refs file. There are other methods to mimic this information entirely in userspace with poor performance: - The mprotect syscall and SIGSEGV handler for bookkeeping - The userfaultfd syscall with the handler for bookkeeping Some benchmarks can be seen here[1]. This series adds features that weren't present earlier: - There is no atomic get soft-dirty PTE bit status and clear operation possible. - The soft-dirty PTE bit of only a part of memory cannot be cleared. Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The procfs interface is enough for finding the soft-dirty bit status and clearing the soft-dirty bit of all the pages of a process. We have the use case where we need to track the soft-dirty PTE bit for only specific pages on demand. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. This syscall is used by games to keep track of dirty pages to process only the dirty pages. The information related to pages if the page is file mapped, present and swapped is required for the CRIU project[2][3]. The addition of the required mask, any mask, excluded mask and return masks are also required for the CRIU project[2]. The IOCTL returns the addresses of the pages which match the specific masks. The page addresses are returned in struct page_region in a compact form. The max_pages is needed to support a use case where user only wants to get a specific number of pages. So there is no need to find all the pages of interest in the range when max_pages is specified. The IOCTL returns when the maximum number of the pages are found. The max_pages is optional. If max_pages is specified, it must be equal or greater than the vec_size. This restriction is needed to handle worse case when one page_region only contains info of one page and it cannot be compacted. This is needed to emulate the Windows getWriteWatch() syscall. Some non-dirty pages get marked as dirty because of the kernel's internal activity (such as VMA merging as soft-dirty bit difference isn't considered while deciding to merge VMAs). The dirty bit of the pages is stored in the VMA flags and in the per page flags. If any of these two bits are set, the page is considered to be soft dirty. Suppose you have cleared the soft dirty bit of half of VMA which will be done by splitting the VMA and clearing soft dirty bit flag in the half VMA and the pages in it. Now kernel may decide to merge the VMAs again. So the half VMA becomes dirty again. This splitting/merging costs performance. The application receives a lot of pages which aren't dirty in reality but marked as dirty. Performance is lost again here. Also sometimes user doesn't want the newly allocated memory to be marked as dirty. PAGEMAP_NO_REUSED_REGIONS flag solves both the problems. It is used to not depend on the soft dirty flag in the VMA flags. So VMA splitting and merging doesn't happen. It only depends on the soft dirty bit of the individual pages. Thus by using this flag, there may be a scenerio such that the new memory regions which are just created, doesn't look dirty when seen with the IOCTL, but look dirty when seen from procfs. This seems okay as the user of this flag know the implication of using it.

[PATCH v16 0/3] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in Documentation/x86/tdx.rst (added by patch 2/3). Following are the details of the patch set: Patch 1/3 -> Preparatory patch for adding attestation support. Patch 2/3 -> Adds user interface driver to support attestation. Patch 3/3 -> Adds selftest support for TDREPORT feature. Commit log history is maintained in the individual patches. Current overall status of this series is, it has no pending issues and can be considered for the upcoming merge cycle.
