Commit 86aa9fc2 authored by Jan Glauber's avatar Jan Glauber Committed by Martin Schwidefsky

[S390] move crypto options and some cleanup.

This patch moves the config options for the s390 crypto instructions
to the standard "Hardware crypto devices" menu. In addition some
cleanup has been done: use a flag for supported keylengths, add a
warning about machien limitation, return ENOTSUPP in case the
hardware has no support, remove superfluous printks and update
email addresses.

config CRYPTO_SHA1_S390
tristate "SHA1 digest algorithm"
depends on S390
select CRYPTO_ALGAPI
help
This is the s390 hardware accelerated implementation of the
SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).
config CRYPTO_SHA256_S390
tristate "SHA256 digest algorithm"
depends on S390
select CRYPTO_ALGAPI
help
This is the s390 hardware accelerated implementation of the
SHA256 secure hash standard (DFIPS 180-2).
This version of SHA implements a 256 bit hash with 128 bits of
security against collision attacks.
config CRYPTO_DES_S390
tristate "DES and Triple DES cipher algorithms"
depends on S390
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
help
This us the s390 hardware accelerated implementation of the
DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).
config CRYPTO_AES_S390
tristate "AES cipher algorithms"
depends on S390
select CRYPTO_ALGAPI
select CRYPTO_BLKCIPHER
help
This is the s390 hardware accelerated implementation of the
AES cipher algorithms (FIPS-197). AES uses the Rijndael
algorithm.
Rijndael appears to be consistently a very good performer in
both hardware and software across a wide range of computing
environments regardless of its use in feedback or non-feedback
modes. Its key setup time is excellent, and its key agility is
good. Rijndael's very low memory requirements make it very well
suited for restricted-space environments, in which it also
demonstrates excellent performance. Rijndael's operations are
among the easiest to defend against power and timing attacks.
On s390 the System z9-109 currently only supports the key size
of 128 bit.
config S390_PRNG
tristate "Pseudo random number generator device driver"
depends on S390
default "m"
help
Select this option if you want to use the s390 pseudo random number
generator. The PRNG is part of the cryptograhic processor functions
and uses triple-DES to generate secure random numbers like the
ANSI X9.17 standard. The PRNG is usable via the char device
/dev/prandom.

This is the s390 hardware accelerated implementation of the
AES cipher algorithms (FIPS-197). AES uses the Rijndael
algorithm.
Rijndael appears to be consistently a very good performer in
both hardware and software across a wide range of computing
environments regardless of its use in feedback or non-feedback
modes. Its key setup time is excellent, and its key agility is
good. Rijndael's very low memory requirements make it very well
suited for restricted-space environments, in which it also
demonstrates excellent performance. Rijndael's operations are
among the easiest to defend against power and timing attacks.
On s390 the System z9-109 currently only supports the key size
of 128 bit.
