Build the entropy device (/dev/random) as a module. This may not be a permanent rule, because this device may eventually be deemed "effectively compulsory", and built by default directly into the kernel. For the moment, however, this is useful for debugging and development. Reviewed by: dfr 2000-06-25 10:12:33 +00:00			`# $FreeBSD$`

Use a consistent style and one much closer to the rest of /usr/src 2001-01-06 14:00:42 +00:00			`.PATH: ${.CURDIR}/../../dev/random`

Reorganise the entropy device so that high-yield entropy sources can more easily be used INSTEAD OF the hard-working Yarrow. The only hardware source used at this point is the one inside the VIA C3 Nehemiah (Stepping 3 and above) CPU. More sources will be added in due course. Contributions welcome! 2004-04-09 15:47:10 +00:00			`SRCS= randomdev.c probe.c`
Decouple yarrow from random(4) device. * Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option. The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow. * random(4) device doesn't really depend on rijndael-. Yarrow, however, does. Add random_adaptors.[ch] which is basically a store of random_adaptor's. random_adaptor is basically an adapter that plugs in to random(4). random_adaptor can only be plugged in to random(4) very early in bootup. Unplugging random_adaptor from random(4) is not supported, and is probably a bad idea anyway, due to potential loss of entropy pools. We currently have 3 random_adaptors: + yarrow + rdrand (ivy.c) + nehemeiah * Remove platform dependent logic from probe.c, and move it into corresponding registration routines of each random_adaptor provider. probe.c doesn't do anything other than picking a specific random_adaptor from a list of registered ones. * If the kernel doesn't have any random_adaptor adapters present then the creation of /dev/random is postponed until next random_adaptor is kldload'ed. * Fix randomdev_soft.c to refer to its own random_adaptor, instead of a system wide one.
