We never parsed/returned any data from .get_link() when the object is a windows reparse-point containing a symlink. This results in the VFS layer oopsing accessing an uninitialized buffer: ... [ 171.407172] Call Trace: [ 171.408039] readlink_copy+0x29/0x70 [ 171.408872] vfs_readlink+0xc1/0x1f0 [ 171.409709] ? readlink_copy+0x70/0x70 [ 171.410565] ? simple_attr_release+0x30/0x30 [ 171.411446] ? getname_flags+0x105/0x2a0 [ 171.412231] do_readlinkat+0x1b7/0x1e0 [ 171.412938] ? __ia32_compat_sys_newfstat+0x30/0x30 ... Fix this by adding code to handle these buffers and make sure we do return a valid buffer to .get_link() CC: Stable <stable@vger.kernel.org> Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com> |

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 Restructured Text 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.
