The current behavior of IP defragmentation is inconsistent: - some overlapping/wrong length fragments are dropped without affecting the queue; - most overlapping fragments cause the whole frag queue to be dropped. This patch brings consistency: if a bad fragment is detected, the whole frag queue is dropped. Two major benefits: - fail fast: corrupted frag queues are cleared immediately, instead of by timeout; - testing of overlapping fragments is now much easier: any kind of random fragment length mutation now leads to the frag queue being discarded (IP packet dropped); before this patch, some overlaps were "corrected", with tests not seeing expected packet drops. Note that in one case (see "if (end&7)" conditional) the current behavior is preserved as there are concerns that this could be legitimate padding.

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.
