* 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.
