Because of .., files outside the share directory could be accessed. To prevent this, normalize the given path and remove all . and .. components. In addition to the usual large set of regression tests (smbtorture and xfstests), ran various tests on this to specifically check path name validation including libsmb2 tests to verify path normalization: ./examples/smb2-ls-async smb://172.30.1.15/homes2/../ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/../ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/../../ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/../ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/..bar/ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/bar../ ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/bar.. ./examples/smb2-ls-async smb://172.30.1.15/homes2/foo/bar../../../../ Signed-off-by: Hyunchul Lee <hyc.lee@gmail.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> 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.
