[PATCH v16 0/6] 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. -- v16: kernel32: Add tests for large page mapping support. ntdll: Validate parameters to NtCreateSection if large pages are requested. server: Use memfd to back anonymous mappings on Linux. kernelbase: Implement GetLargePageMinimum by returning the value of LargePageMinimum in _KUSER_SHARED_DATA. server: Set LargePageMinimum in _KUSER_SHARED_DATA on Linux. server: Require SeLockMemoryPrivilege to create large page mappings. 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 101981ad8df..d9d4a51c054 100755 --- a/configure +++ b/configure @@ -7995,6 +7995,12 @@ 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$ac_cv_header_linux_param_h" = xyes @@ -20787,6 +20793,12 @@ if test "x$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 231ec7f17d6..e63c97900b2 100644 --- a/configure.ac +++ b/configure.ac @@ -384,6 +384,7 @@ AC_CHECK_HEADERS(\ linux/input.h \ linux/ioctl.h \ linux/major.h \ + linux/memfd.h \ linux/param.h \ linux/serial.h \ linux/types.h \ @@ -2079,6 +2080,7 @@ 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 ef783c75a42..923d943de01 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 04cd60a1d01..1cf018db629 100644 --- a/server/mapping.c +++ b/server/mapping.c @@ -325,13 +325,117 @@ 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.
