If SMB2_OP_QUERY_INFO (called when POSIX extensions are not used) failed with STATUS_ACCESS_DENIED then it means that caller does not have permission to open the path with FILE_READ_ATTRIBUTES access and therefore cannot issue SMB2_OP_QUERY_INFO command. This will result in the -EACCES error from stat() sycall. There is an alternative way how to query limited information about path but still suitable for stat() syscall. SMB2 OPEN/CREATE operation returns in its successful response subset of query information. So try to open the path without FILE_READ_ATTRIBUTES but with MAXIMUM_ALLOWED access which will grant the maximum possible access to the file and the response will contain required query information for stat() syscall. This will improve smb2_query_path_info() to query also files which do not grant FILE_READ_ATTRIBUTES access to caller.
