This patch will introduce ROOT_ITEM check, which includes: - Key->objectid and key->offset check Currently only some easy check, e.g. 0 as rootid is invalid. - Item size check Root item size is fixed. - Generation checks Generation, generation_v2 and last_snapshot should not be greater than super generation + 1 - Level and alignment check Level should be in [0, 7], and bytenr must be aligned to sector size. - Flags check Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203261 Reported-by: Jungyeon Yoon <jungyeon.yoon@gmail.com> Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.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.
