GCC 8.4 miscompiles dwarf2expr.c with -O2 or -O1 for earmv7hf{,eb}, which
results in crashes described in the PRs. No upstream fixes up to now. So,
let us disable optimization for this file.
Note that this affects only earmv7hf{,eb} as far as I can see. Crashes do
not occur neither for earmv6hf{,eb} nor earmv7{,eb}.

The file format was defined with a machine-dependent 32-bit integer field (the estimated number of bits of entropy in the process that generated it). Take whichever byte order gives a number that is reasonable, i.e. lower than the number of bits in the buffer. Continue to have `rndctl -S' generate it in machine-dependent byte order for now, so that if you roll back to an older rndctl(8) then `rndctl -L' on the same machine will still be able to load it with the right entropy estimate. In a future revision, perhaps we can change it to be little-endian.

Primary goals: 1. Use cryptography primitives designed and vetted by cryptographers. 2. Be honest about entropy estimation. 3. Propagate full entropy as soon as possible. 4. Simplify the APIs. 5. Reduce overhead of rnd_add_data and cprng_strong. 6. Reduce side channels of HWRNG data and human input sources. 7. Improve visibility of operation with sysctl and event counters. Caveat: rngtest is no longer used generically for RND_TYPE_RNG rndsources. Hardware RNG devices should have hardware-specific health tests. For example, checking for two repeated 256-bit outputs works to detect AMD's 2019 RDRAND bug. Not all hardware RNGs are necessarily designed to produce exactly uniform output. ENTROPY POOL - A Keccak sponge, with test vectors, replaces the old LFSR/SHA-1 kludge as the cryptographic primitive. - `Entropy depletion' is available for testing purposes with a sysctl knob kern.entropy.depletion; otherwise it is disabled, and once the system reaches full entropy it is assumed to stay there as far as modern cryptography is concerned. - No `entropy estimation' based on sample values. Such `entropy estimation' is a contradiction in terms, dishonest to users, and a potential source of side channels. It is the responsibility of the driver author to study the entropy of the process that generates the samples. - Per-CPU gathering pools avoid contention on a global queue. - Entropy is occasionally consolidated into global pool -- as soon as it's ready, if we've never reached full entropy, and with a rate limit afterward. Operators can force consolidation now by running sysctl -w kern.entropy.consolidate=1. - rndsink(9) API has been replaced by an epoch counter which changes whenever entropy is consolidated into the global pool. . Usage: Cache entropy_epoch() when you seed. If entropy_epoch() has changed when you're about to use whatever you seeded, reseed. . Epoch is never zero, so initialize cache to 0 if you want to reseed on first use. . Epoch is -1 iff we have never reached full entropy -- in other words, the old rnd_initial_entropy is (entropy_epoch() != -1) -- but it is better if you check for changes rather than for -1, so that if the system estimated its own entropy incorrectly, entropy consolidation has the opportunity to prevent future compromise. - Sysctls and event counters provide operator visibility into what's happening: . kern.entropy.needed - bits of entropy short of full entropy . kern.entropy.pending - bits known to be pending in per-CPU pools, can be consolidated with sysctl -w kern.entropy.consolidate=1 . kern.entropy.epoch - number of times consolidation has happened, never 0, and -1 iff we have never reached full entropy CPRNG_STRONG - A cprng_strong instance is now a collection of per-CPU NIST Hash_DRBGs. There are only two in the system: user_cprng for /dev/urandom and sysctl kern.?random, and kern_cprng for kernel users which may need to operate in interrupt context up to IPL_VM. (Calling cprng_strong in interrupt context does not strike me as a particularly good idea, so I added an event counter to see whether anything actually does.) - Event counters provide operator visibility into when reseeding happens.

Unserialized accesses broke the" It is no longer necessary to serialize calls to rnd_add_data, so we can use the same rndsource for every queue. This also reverts some unrelated changes that were mixed in: 1. WM_NRXDESC was made unsigned 2. The specific samples were changed. (1) will be redone in a separate commit. (2) was buggy (wrote `=' where `|=' was meant) and is not needed; it's fine to do rnd_add_data in a thread or softint too, not just in a hard interrupt handler.

The file format was defined with a machine-dependent 32-bit integer field (the estimated number of bits of entropy in the process that generated it). Fortunately we have a checksum to verify the order. This way you can use `rndctl -S' on a little-endian machine to generate a seed when installing NetBSD on a big-endian machine, and the kernel will accept it on boot.
