When enumerating snapshots, the last few bytes of the final snapshot could be left off since we were miscalculating the length returned (leaving off the sizeof struct SRV_SNAPSHOT_ARRAY) See MS-SMB2 section 2.2.32.2. In addition fixup the length used to allow smaller buffer to be passed in, in order to allow returning the size of the whole snapshot array more easily. Sample userspace output with a kernel patched with this (mounted to a Windows volume with two snapshots). Before this patch, the second snapshot would be missing a few bytes at the end. ~/cifs-2.6# ~/enum-snapshots /mnt/file press enter to issue the ioctl to retrieve snapshot information ... size of snapshot array = 102 Num snapshots: 2 Num returned: 2 Array Size: 102 Snapshot 0:@GMT-2018.06.30-19.34.17 Snapshot 1:@GMT-2018.06.30-19.33.37 CC: Stable <stable@vger.kernel.org> Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Pavel Shilovsky <pshilov@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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
