Previously, the call to get_file_attribute for FIFOs set the first argument to NULL instead of the handle h returned by get_stat_handle, thereby forcing the file to be opened for fetching the security descriptor in get_file_sd(). This was done because h might have been a pipe handle rather than a file handle, and its permissions would not necessarily reflect those of the file.
That situation can no longer occur with the new fhandler_fifo::fstat introduced in the previous commit. --- winsup/cygwin/fhandler_disk_file.cc | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/winsup/cygwin/fhandler_disk_file.cc b/winsup/cygwin/fhandler_disk_file.cc index ef9171bbf..6170427b0 100644 --- a/winsup/cygwin/fhandler_disk_file.cc +++ b/winsup/cygwin/fhandler_disk_file.cc @@ -475,8 +475,7 @@ fhandler_base::fstat_helper (struct stat *buf) else if (pc.issocket ()) buf->st_mode = S_IFSOCK; - if (!get_file_attribute (is_fs_special () && !pc.issocket () ?
