[PATCH v4 0/9] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) May 31, 2024

May 31, 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. -- v4: virtual_get_min_large_page_size: initialize min_size to 0 https://gitlab.winehq.org/wine/wine/-/merge_requests/5769

(it's probably not 100% perfectly > designed but I mean the general idea) I've updated the branch with prototype chains; there's a lot of commits in-between so please ignore them for now (some are split, some aren't ready for upstream review), since order (same as from Proton) is like: basic proxy impl->cycle collection integration->proper global host window->basic prototypes (only one, no chains)->constructors->prototype chains Probably first commit of interest would be `d672d8b44ef084106c59b30fa01952fe4daf9189` aka `mshtml: Copy the builtin data to the proxy prototype on init.` Or you can just run the tests and change the BuiltinFuncCall to use the DISPID (no need to check IID for testing), proxy_prop_info should already get the dispid anyway (for proxy props) and see why it fails. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/5444#note_71942
