X-BeenThere: cerowrt-devel@lists.bufferbloat.net X-Mailman-Version: 2.1.13 Precedence: list List-Id: Development issues regarding the cerowrt test router project List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 18 Oct 2013 00:40:40 -0000 This new design for a rng actually appears to be pretty reasonable. http://thread.gmane.org/gmane.linux.kernel.cryptoapi/9878 Full details, paper, and code patches here: http://www.chronox.de/ I am (as usual) low on time to package it up for openwrt, or patch it into the kernel, and try it. I will probably be able to get around to it next weekend if nobody beats me to it, slamming it into my pie build for x86 first. I'd be very interested if some folk could compare the standalone daemon to rngd on their favorite platform? And if anyone here has the chops to think hard about the algo, that would be nice, too... In other news , theodore ts'o's got a whole bunch more new patches for the random driver on kernel.org that I HAVE patched in and am trying to get into the next cero release. Fixes for get_cycles(), arrived already in mainline, and the mips patch is around somewhere. While that stuff improves the quality of the entropy in the system, the above rng would bring *more* entropy into the system, maybe get rid of the existing daemon (or integrate with it) and/or hostapd patches, etc, which I find exciting. That said, validating rng stuff is *hard*. --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
