[PATCH v10 0/21] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) June 3, 2024

June 3, 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. -- v10: make_memfd_name: Fix format specifiers. This merge request has too many patches to be relayed via email.

[PATCH v2 0/5] MR5764: win32u: Create bitmaps for window surface pixels.
by Rémi Bernon June 3, 2024

June 3, 2024

This should help unifying the interface and get rid of the get_info callback. Later, I think we could create bitmaps over sections shared with some DWM process and/or host compositor. -- v2: win32u: Create a HBITMAP backing the window surface pixels. winex11: Create a HBITMAP for the allocated surface pixels. winex11: Create XImage before initializing the window surface. win32u: Pass BITMAPINFO and a HBITMAP to window_surface_init. win32u: Move the window surface color bits to the common struct. https://gitlab.winehq.org/wine/wine/-/merge_requests/5764

[PATCH 0/1] MR5353: ddraw: Allow table to grow
by David Kahurani (＠ReDress) June 3, 2024

June 3, 2024

This table doesn't really grow when the total number of handles exceeds the initial size. It will instead try to wrap and lead to an access violation. Signed-off-by: David Kahurani <k.kahurani(a)gmail.com> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5353

[PATCH 0/1] MR4773: ntdll: Derive not readable DMI's serial numbers from machine's GUID.
by eric pouech (＠epo) June 3, 2024

June 3, 2024

Project Kunai associates cloud account with a mix of various items, including board serial number, resulting in several machines being bound to the same cloud account because the momo serial number is always empty. Note: this patch doesn't follow the systemd guidelines of not exposing directly /etc/machine-id content (but Wine already exposes /etc/machine-id as Windows machine GUID).
