[PATCH v35 0/9] MR5769: Add support for large page backed file mapping objects on Linux.
by Vibhav Pant (＠vibhavp) July 9, 2024

July 9, 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. -- v35: advapi32: Fake the SeLockMemoryPrivilege right in LsaEnumerateAccountRights. https://gitlab.winehq.org/wine/wine/-/merge_requests/5769

[PATCH v9 0/2] MR5969: kernelbase: Ensure null termination in RegGetValue[AW].
by Alex Henrie (＠alexhenrie) July 9, 2024

July 9, 2024

I was hoping that the new tests would provide evidence that RtlQueryRegistryValues uses RegGetValue to ensure that multi-strings are double-null-terminated. Instead the tests suggest that my hypothesis was wrong because RegGetValue only ensures single null termination, not double null termination. We should fix RegGetValue anyway for the sake of applications that expect it to null-terminate. -- v9: kernelbase: Ensure null termination in RegGetValue[AW]. https://gitlab.winehq.org/wine/wine/-/merge_requests/5969

Re: [PATCH v2 0/1] MR6002: secur32: Implement the NameDisplay name format of the GetUserNameExW method
by Hans Leidekker (＠hans) July 9, 2024

July 9, 2024

In my tests GetUserNameEx(NameDisplay) returns ERROR_NONE_MAPPED on Windows. It seems that the Windows machine needs to be joined to a Windows domain for this call to return something sensible. Do you have an application that depends this? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6002#note_75538

[PATCH 0/1] MR6021: nsiproxy.sys: Use net.inet.tcp.pcblist64 to enumerate connections on macOS.
by Tim Clem (＠tclem) July 9, 2024

July 9, 2024

The handles returned by libproc (namely struct socket_info's soi_pcb) use all 64 bits, but the ones from the pcblist sysctl are truncated to 32. That makes find_owning_pid fail. The pcblist64 sysctl was added in macOS 10.6 and returns handles that match those from libproc. -- There does not seem to be a MIB constant for pcblist64, so I had to fetch it with sysctlbyname. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6021
