Masanari Iida 12f7c14aa6 crypto: doc - Fix typo in crypto-API.xml
This patch fix some typos found in crypto-API.xml.
It is because the file is generated from comments in sources,
so I had to fix typo in sources.

Herbert Xu 94f1bb15be crypto: rng - Remove old low-level rng interface
Now that all rng implementations have switched over to the new
interface, we can remove the old low-level interface.

Herbert Xu 7ca99d8148 crypto: rng - Add crypto_rng_set_entropy
This patch adds the function crypto_rng_set_entropy.  It is only
meant to be used by testmgr when testing RNG implementations by
providing fixed entropy data in order to verify test vectors.

Herbert Xu acec27ff35 crypto: rng - Convert low-level crypto_rng to new style
This patch converts the low-level crypto_rng interface to the
"new" style.

This allows existing implementations to be converted over one-
by-one.  Once that is complete we can then remove the old rng
interface.

Herbert Xu 3c5d8fa9f5 crypto: rng - Mark crypto_rng_reset seed as const
There is no reason why crypto_rng_reset should modify the seed
so this patch marks it as const.  Since our algorithms don't
export a const seed function yet we have to go through some
contortions for now.

Herbert Xu ff030b099a crypto: rng - Introduce crypto_rng_generate
This patch adds the new top-level function crypto_rng_generate
which generates random numbers with additional input.  It also
extends the mid-level rng_gen_random function to take additional
data as input.

Herbert Xu d0e83059a6 crypto: rng - Convert crypto_rng to new style crypto_type
This patch converts the top-level crypto_rng to the "new" style.
It was the last algorithm type added before we switched over
to the new way of doing things exemplified by shash.

All users will automatically switch over to the new interface.

Note that this patch does not touch the low-level interface to
rng implementations.

Stephan Mueller cde001e4c3 crypto: rng - RNGs must return 0 in success case
Change the RNGs to always return 0 in success case.

This patch ensures that seqiv.c works with RNGs other than krng. seqiv
expects that any return code other than 0 is an error. Without the
patch, rfc4106(gcm(aes)) will not work when using a DRBG or an ANSI
X9.31 RNG.

Neil Horman 17f0f4a47d crypto: rng - RNG interface and implementation
This patch adds a random number generator interface as well as a
cryptographic pseudo-random number generator based on AES.  It is
meant to be used in cases where a deterministic CPRNG is required.

One of the first applications will be as an input in the IPsec IV
generation process.
