Jason A. Donenfeld says: ==================== Introduce The SipHash PRF This patch series introduces SipHash into the kernel. SipHash is a cryptographically secure PRF, which serves a variety of functions, and is introduced in patch #1. The following patch #2 introduces HalfSipHash, an optimization suitable for hash tables only. Finally, the last two patches in this series show two usages of the introduced siphash function family. It is expected that after this initial introduction, other usages will follow. Please read the extensive descriptions in patch #1 and patch #2 of what these functions do and the various levels of assurances. They're products of intense cryptographic research, and I believe they're suitable for the uses outlined herein. The use of SipHash is not limited to the networking subsystem -- indeed I would like to use it in other places too in the kernel. But after discussing with a few on this list and at Linus' suggestion, the initial import of these functions is coming through the networking tree. After these are merged, it will then be easier to expand use elsewhere. Changes v2->v3: - hsiphash keys now simply use an unsigned long, in order to avoid a cluttered ifdef and make it a bit more clear what's happening. - A typo in the documentation has been fixed. - The documentation has been augmented with an example relating to struct packing and passing. - The net_secret variable is now __read_mostly. Hopefully this is the last of the required revisions, and v3 can be merged into net-next. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
