[PATCH v34 0/8] MR5769: Add support for large page backed file mapping objects on Linux.
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

From: Vibhav Pant <vibhavp(a)gmail.com> On Linux, try creating a memfd first to implement create_temp_file. If a large page mapping is requested (SEC_LARGE_PAGES), create a memfd with the MFD_HUGETLB flags. If SEC_COMMIT is passed, allocate sufficient space to back the mapping with posix_fallocate. Additionally, ensure when SEC_LARGE_PAGES is requested, ensure that SEC_COMMIT is passed as well. --- configure | 12 +++++ configure.ac | 2 + include/config.h.in | 6 +++ server/mapping.c | 118 ++++++++++++++++++++++++++++++++++++++++++-- 4 files changed, 134 insertions(+), 4 deletions(-) diff --git a/configure b/configure index 9ef4dfef5a4..24ff184de39 100755 --- a/configure +++ b/configure @@ -7986,6 +7986,12 @@ if test "x$ac_cv_header_linux_major_h" = xyes then : printf "%s\n" "#define HAVE_LINUX_MAJOR_H 1" >>confdefs.h +fi +ac_fn_c_check_header_compile "$LINENO" "linux/memfd.h" "ac_cv_header_linux_memfd_h" "$ac_includes_default" +if test "x$ac_cv_header_linux_memfd_h" = xyes +then : + printf "%s\n" "#define HAVE_LINUX_MEMFD_H 1" >>confdefs.h + fi ac_fn_c_check_header_compile "$LINENO" "linux/param.h" "ac_cv_header_linux_param_h" "$ac_includes_default" if test "x$ac_cv_header_linux_param_h" = xyes @@ -20812,6 +20818,12 @@ if test "x$ac_cv_func_mach_continuous_time" = xyes then : printf "%s\n" "#define HAVE_MACH_CONTINUOUS_TIME 1" >>confdefs.h +fi +ac_fn_c_check_func "$LINENO" "memfd_create" "ac_cv_func_memfd_create" +if test "x$ac_cv_func_memfd_create" = xyes +then : + printf "%s\n" "#define HAVE_MEMFD_CREATE 1" >>confdefs.h + fi ac_fn_c_check_func "$LINENO" "pipe2" "ac_cv_func_pipe2" if test "x$ac_cv_func_pipe2" = xyes diff --git a/configure.ac b/configure.ac index 6f48132b22a..092ca64849e 100644 --- a/configure.ac +++ b/configure.ac @@ -380,6 +380,7 @@ AC_CHECK_HEADERS(\ linux/input.h \ linux/ioctl.h \ linux/major.h \ + linux/memfd.h \ linux/param.h \ linux/serial.h \ linux/types.h \ @@ -2078,6 +2079,7 @@ AC_CHECK_FUNCS(\ getrandom \ kqueue \ mach_continuous_time \ + memfd_create \ pipe2 \ port_create \ posix_fadvise \ diff --git a/include/config.h.in b/include/config.h.in index aa066a87ad7..bbd5a57a280 100644 --- a/include/config.h.in +++ b/include/config.h.in @@ -180,6 +180,9 @@ /* Define to 1 if you have the <linux/major.h> header file. */ #undef HAVE_LINUX_MAJOR_H +/* Define to 1 if you have the <linux/memfd.h> header file. */ +#undef HAVE_LINUX_MEMFD_H + /* Define to 1 if you have the <linux/param.h> header file. */ #undef HAVE_LINUX_PARAM_H @@ -219,6 +222,9 @@ /* Define to 1 if you have the <mach-o/loader.h> header file. */ #undef HAVE_MACH_O_LOADER_H +/* Define to 1 if you have the 'memfd_create' function. */ +#undef HAVE_MEMFD_CREATE + /* Define to 1 if you have the <mntent.h> header file. */ #undef HAVE_MNTENT_H diff --git a/server/mapping.c b/server/mapping.c index 30be548fd53..04b35d6ec4a 100644 --- a/server/mapping.c +++ b/server/mapping.c @@ -355,13 +355,117 @@ static int check_current_dir_for_exec(void) return (ret != MAP_FAILED); } +#ifdef HAVE_MEMFD_CREATE +static void make_memfd_name( const char *prefix, ULONG sec_flags, char *dest ) +{ + /* memfd names are restricted to 250 bytes including \0, but are only meant for debugging, with + * duplicate names not causing any side-effects. */ + + if (prefix != NULL) + { + snprintf( dest, 250, "map-%s-%x", prefix, (int)sec_flags ); + } + else + { + snprintf( dest, 250, "map-%x", (int)sec_flags ); + } +} + +static int create_memfd( ULONG file_access, ULONG sec_flags, file_pos_t new_size, int *err ) +{ + int fd; + off_t size = new_size; + char memfd_name[256]; + unsigned int memfd_flags = MFD_ALLOW_SEALING; + unsigned int seal_flags = F_SEAL_SEAL | F_SEAL_WRITE; + +#ifdef HAVE_POSIX_FALLOCATE + if (sizeof(file_pos_t) > sizeof(off_t) && size != new_size) + { + *err = EINVAL; + return -1; + } +#endif +#ifdef MFD_EXEC + memfd_flags |= MFD_EXEC; +#endif + + make_memfd_name( NULL, sec_flags, memfd_name ); + + if (sec_flags & SEC_LARGE_PAGES) + { + memfd_flags |= MFD_HUGETLB; + } + fd = memfd_create( memfd_name, memfd_flags ); + if (fd == -1) + { + if (errno == EINVAL && (sec_flags & SEC_LARGE_PAGES)) + { + /* MFD_HUGETLB & MFD_ALLOW_SEALING is only available in Linux >= 4.16.

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=146683 Your paranoid android. === debian11b (64 bit WoW report) === kernel32: virtual.c:1473: Test failed: MapViewOfFile failed (87) virtual.c:631: Test failed: VirtualAlloc failed (87) virtual.c:647: Test failed: VirtualAlloc failed (87) virtual.c:672: Test failed: VirtualAlloc2 failed (87) virtual.c:679: Test failed: VirtualAlloc2 failed (87) ntdll: virtual.c:758: Test failed: NtAllocateVirtualMemoryEx failed (c000000d) virtual.c:777: Test failed: NtAllocateVirtualMemoryEx failed unexpectedly (c000000d) psapi: psapi_main.c:1289: Test failed: VirtualAlloc failed (87)
