When SMB 3.1.1 POSIX Extensions are negotiated, userspace applications using readdir() or getdents() calls without stat() on each individual file (such as a simple "ls" or "find") would misidentify file types and exhibit strange behavior such as not descending into directories. The reason for this behavior is an oversight in the cifs_posix_to_fattr conversion function. Instead of extracting the entry type for cf_dtype from the properly converted cf_mode field, it tries to extract the type from the PDU. While the wire representation of the entry mode is similar in structure to POSIX stat(), the assignments of the entry types are different. Applying the S_DT macro to cf_mode instead yields the correct result. This is also what the equivalent function smb311_posix_info_to_fattr in inode.c already does for stat() etc.; which is why "ls -l" would give the correct file type but "ls" would not (as identified by the colors).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
