It turns out that LRW has never worked properly on big endian.
This was never discussed because nobody actually used it that
way. In fact, it was only discovered when Geert Uytterhoeven
loaded it through tcrypt which failed the test on it.
The fix is straightforward, on big endian the to find the nth
bit we should be grouping them by words instead of bytes. So
setbit128_bbe should xor with 128 - BITS_PER_LONG instead of
128 - BITS_PER_BYTE == 0x78.

[CRYPTO] lrw: Replace all adds to big endians variables with be*_add_cpu2008-04-21T02:19:22ZMarcin Slusarzmarcin.slusarz@gmail.com2008-03-14T08:22:53Zurn:sha1:fd4609a8e00a867303783ade62d67953fb72adc8
replace all:
big_endian_variable = cpu_to_beX(beX_to_cpu(big_endian_variable) +
expression_in_cpu_byteorder);
with:
beX_add_cpu(&big_endian_variable, expression_in_cpu_byteorder);

[CRYPTO] templates: Pass type/mask when creating instances2007-05-02T04:38:31ZHerbert Xuherbert@gondor.apana.org.au2007-01-01T07:37:02Zurn:sha1:ebc610e5bc76df073221e64e86c3f7533a09ea40
This patch passes the type/mask along when constructing instances of
templates. This is in preparation for templates that may support
multiple types of instances depending on what is requested. For example,
the planned software async crypto driver will use this construct.
For the moment this allows us to check whether the instance constructed
is of the correct type and avoid returning success if the type does not
match.

[CRYPTO] lrw: Liskov Rivest Wagner, a tweakable narrow block cipher mode2006-12-07T02:38:56ZRik Snelrsnel@cube.dyndns.org2006-11-25T22:43:10Zurn:sha1:64470f1b8510699dc357a44004dc924bc139c917
Main module, this implements the Liskov Rivest Wagner block cipher mode
in the new blockcipher API. The implementation is based on ecb.c.
The LRW-32-AES specification I used can be found at:
http://grouper.ieee.org/groups/1619/email/pdf00017.pdf
It implements the optimization specified as optional in the
specification, and in addition it uses optimized multiplication
routines from gf128mul.c.
Since gf128mul.[ch] is not tested on bigendian, this cipher mode
may currently fail badly on bigendian machines.
