[PATCH v5 0/14] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) June 1, 2024

June 1, 2024

This MR adds support for creating file mapping objects backed by large pages on Linux, by making the following changes: ## wineserver * On Linux, `create_temp_file` will first attempt to use memfds as the backing fd. If it fails, it'll return to the current codepath, creating a temporary file in either the server or config directory. * The created memfd will be sealed against writes, if the caller requesting the appropriate page protection flags. * This removes the requirement that FDs be only created on filesystems/directories that aren't `noexec`. * In the server method `create_mapping` , if large pages have been requested by the caller, hold that the calling thread's token holds `SeLockMemoryPrivilege` . * Additionally, add `SeLockMemoryPrivilege` to the list of privileges enabled for the Administrator. ## `ntdll` * Add `virtual_get_min_large_page_size` and its exported wrapper `wine_unix_get_min_large_page_size`. * On Linux, the minimum page size is determined by going through `/sys/kernel/mm/hugepages`. If hugepage support was not detected, `STATUS_NOT_SUPPORTED` is returned instead. On other platforms, the older hard-coded value of 2\*1024\*1024 is returned instead. * `NtCreateSection` will validate certain parameters if large pages are requested. Specifically, it will return STATUS_INVALID_PARAMETER if the requested mapping is not anonymous/unnamed, or the size is not a multiple of the minimum supported page size. ## `kernelbase` * `GetLargePageMinimum` will use `wine_unix_get_min_large_page_size`. ## `kernel32/tests` * Add new test test_large_page_file_mapping, which validates privilege enforcements and parameter validation while creating large pages backed file mapping obejcts. The tests are skipped if `GetLargePageMinimum` returns 0. -- v5: create_user_data_mapping: Set the LargePageMinimum field. Remove declaration for wine_unix_get_min_large_page_size. Add checks for linux/memfd.h and memfd_create on Linux. :NtCreateSection: remove trailing whitespace. Remove virtual_get_large_page_min_size and its exported wine syscall https://gitlab.winehq.org/wine/wine/-/merge_requests/5769

[PATCH v19 0/1] MR5752: msvcrt: [PR53960] Fix ucrt has different struct layout than msvcrt
by cqwrteur (＠trcrsired) June 1, 2024

June 1, 2024

UCRT's FILE struct and fd struct have different layouts, and their locks are different. Implementation in Wine does not match UCRT in Windows, causing ABI issues. see: https://bugs.winehq.org/show_bug.cgi?id=53960 -- v19: [PATCH] msvcrt: Fix FILE in ucrt which incorrect layout https://gitlab.winehq.org/wine/wine/-/merge_requests/5752
