Linus Torvalds 52f6c588c7 Add wait_for_random_bytes() and get_random_*_wait() functions so that ... callers can more safely get random bytes if they can block until the CRNG is initialized. Also print a warning if get_random_*() is called before the CRNG is initialized. By default, only one single-line warning will be printed per boot. If CONFIG_WARN_ALL_UNSEEDED_RANDOM is defined, then a warning will be printed for each function which tries to get random bytes before the CRNG is initialized. This can get spammy for certain architecture types, so it is not enabled by default. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAllqXNUACgkQ8vlZVpUN gaPtAgf/aUbXZuWYsDQzslHsbzEWi+qz4QgL885/w4L00pEImTTp91Q06SDxWhtB KPvGnZHS3IofxBh2DC+6AwN6dPMoWDCfYhhO6po3FSz0DiPRIQCTuvOb8fhKY1X7 rTdDq2xtDxPGxJ25bMJtlrgzH2XlXPpVyPUeoc9uh87zUK5aesXpUn9kBniRexoz ume+M/cDzPKkwNQpbLq8vzhNjoWMVv0FeW2akVvrjkkWko8nZLZ0R/kIyKQlRPdG LZDXcz0oTHpDS6+ufEo292ZuWm2IGer2YtwHsKyCAsyEWsUqBz2yurtkSj3mAVyC hHafyS+5WNaGdgBmg0zJxxwn5qxxLg== =ua7p -----END PGP SIGNATURE----- Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random Pull random updates from Ted Ts'o: "Add wait_for_random_bytes() and get_random_*_wait() functions so that callers can more safely get random bytes if they can block until the CRNG is initialized.
