src/sys/dev/random/other_algorithm.c, branch release/12.3.0 FreeBSD source tree https://cgit-dev.freebsd.org/src/atom?h=release%2F12.3.0 2018-08-26T12:51:46Z Remove the Yarrow PRNG algorithm option in accordance with due notice 2018-08-26T12:51:46Z Mark Murray markm@FreeBSD.org 2018-08-26T12:51:46Z urn:sha1:19fa89e93888ebfe79d06c7b831bcd39001dce63 given in random(4). This includes updating of the relevant man pages, and no-longer-used harvesting parameters. Ensure that the pseudo-unit-test still does something useful, now also with the "other" algorithm instead of Yarrow.

Differential Revision: https://reviews.freebsd.org/D3929 Add DEV_RANDOM pseudo-option and use it to "include out" random(4) 2015-08-17T07:36:12Z Mark Murray markm@FreeBSD.org 2015-08-17T07:36:12Z urn:sha1:646041a89aeab0d79fa350c401de57e1c8b85ac2 if desired. Retire randomdev_none.c and introduce random_infra.c for resident infrastructure. Completely stub out random(4) calls in the "without DEV_RANDOM" case. Add RANDOM_LOADABLE option to allow loadable Yarrow/Fortuna/LocallyWritten algorithm. Add a skeleton "other" algorithm framework for folks to add their own processing code. NIST, anyone? Retire the RANDOM_DUMMY option. Build modules for Yarrow, Fortuna and "other". Use atomics for the live entropy rate-tracking. Convert ints to bools for the 'seeded' logic. Move _write() function from the algorithm-specific areas to randomdev.c Get rid of reseed() function - it is unused. Tidy up the opt_*.h includes. Update documentation for random(4) modules. Fix test program (reviewers, please leave this). Differential Revision: https://reviews.freebsd.org/D3354 Reviewed by: wblock,delphij,jmg,bjk Approved by: so (/dev/random blanket)
