important is the use of a ChaCha20-based CRNG for /dev/urandom, which is faster, more efficient, and easier to make scalable for silly/abusive userspace programs that want to read from /dev/urandom in a tight loop on NUMA systems. This set of patches also improves entropy gathering on VM's running on Microsoft Azure, and will take advantage of a hw random number generator (if present) to initialize the /dev/urandom pool. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABCAAGBQJXla/8AAoJEPL5WVaVDYGj4xgH/3qDPHpFvynUMbMgg/MRQNt2 K1zhKKQjYuJ465aIiPME21tGC1C5JxO3a9mgDy0pfJmLVvCWRUx9dDtdI59Xkaev KuVTbqdl8D75lftX3/jF3lXKd5dVLrW2V9hOMcESQqBFuoc1B8sJztR0upQsdGvA I8+jjxRffSzxDZY4it6p/lqsTdEfwhA+mEc6ztZ+Ccsdlqd+GNCvB/YE4tk+U6x/ tGKaKfuiHSXpR4P9ks/L5gwaIcFQ6Y1rdVqd8YP3iC9YXGFZdJkRXklRRj1mCgWs YoCDMATTos+6iVONft94fF5pW6HND1F3bxPNo/RpMZca3MlqbiCSij3ky+gqUc4= =mSBt -----END PGP SIGNATURE----- Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random Pull random driver updates from Ted Ts'o: "A number of improvements for the /dev/random driver; the most important is the use of a ChaCha20-based CRNG for /dev/urandom, which is faster, more efficient, and easier to make scalable for silly/abusive userspace programs that want to read from /dev/urandom in a tight loop on NUMA systems.

Oh well). * tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random: random: strengthen input validation for RNDADDTOENTCNT random: add backtracking protection to the CRNG random: make /dev/urandom scalable for silly userspace programs random: replace non-blocking pool with a Chacha20-based CRNG random: properly align get_random_int_hash random: add interrupt callback to VMBus IRQ handler random: print a warning for the first ten uninitialized random users random: initialize the non-blocking pool via add_hwgenerator_randomness() |
