[PATCH v34 0/8] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) 30 Jun '24

30 Jun '24

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. -- v34: psapi: Add tests for querying information for large pages. ntdll: Use PAGEMAP_SCAN ioctl to implement get_working_set_ex, if available. kernel32: Add tests for large pages support. https://gitlab.winehq.org/wine/wine/-/merge_requests/5769

[PATCH 0/1] MR5957: win32u: fix random crash without libfreetype
by Fan WenJie (＠fanwenjie) 30 Jun '24

without freetype, some calling return failed, so some value may not be initialized (it initialize by some failed calling and pass argument by point of it), it would cause random crash! Signed-off-by: Fan WenJie <fanwj(a)mail.ustc.edu.cn> -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5957

I am contributing to wine for more than 10 years. I admit that I might be wrong in understanding the code. Please try to communicate and present in a decent way as it will rub the people in a wrong way. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5771#note_74757

@infyquest I'm happy you tried to make a fix, I'm happy you have interest in wine. > I dont need you to teach me code, Please don't make it personal. This ain't personal, if someone want to make a fix, they need at least to understand the code they send, this is the same with everyone. I know you wanted to do good, but this doesn't change what this code effectively does. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5771#note_74756
