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 --- 17650f22cd059b3d653c03b5534e4a2a18cb02bd
