crypto: s390 - cleanup DES code

2011-05-04T05:05:52+00:00

Remove a stale file left over from 1efbd15c3bc2b79d33e033e898211109c32159fa
and and cleanup the DES code a bit to make it easier to add new code.

crypto: s390 - extend crypto facility check

2011-05-04T05:05:49+00:00

The specification which crypto facility is required for an algorithm is added
as a parameter to the availability check which is done before an algorithm is
registered. With this change it is easier to add new algorithms that require
different facilities.

[S390] prng: fix pointer arithmetic

2011-04-27T07:34:45+00:00

The git commit c708c57e247775928b9a6bce7b4d8d14883bf39b fixed the
access beyond the end of the stack in prng_seed but the pointer
arithmetic is still incorrect. The calculation has been off by
a factor of 64, now it is only off by a factor of 8. prng_seed
is called with a maximum of 16 for nbytes, small enough that
the incorrect calculation stays insides the limits of the stack.
Place parentheses for correct pointer arithmetic.

[S390] prng: prevent access beyond end of stack

2011-04-20T08:15:43+00:00

While initializing the state of the prng only the first 8 bytes of
random data where used, the second 8 bytes were read from the memory
after the stack. If only 64 bytes of the kernel stack are used and
CONFIG_DEBUG_PAGEALLOC is enabled a kernel panic may occur because of
the invalid page access. Use the correct multiplicator to stay within
the random data buffer.

crypto: sha-s390 - Reset index after processing partial block

2011-02-07T09:26:06+00:00

The partial block handling in sha-s390 is broken when we get a
partial block that is followed by an update which fills it with
bytes left-over.  Instead of storing the newly left-over bytes
at the start of the buffer, it will be stored immediately after
the previous partial block.

This patch fixes this by resetting the index pointer.

[S390] cleanup facility list handling

2010-10-25T14:10:21+00:00

Store the facility list once at system startup with stfl/stfle and
reuse the result for all facility tests.
