2014-06-16util: Add InvMixColumnsTom Musta1-0/+265
This patch adds the table implementation of the Advanced Encryption Standard (AES) InvMixColumns transformation. The patch is intentionally asymmetrical -- the MixColumns table is not added because there is no known use for it at this time.

2014-06-16util: Add AES ShiftRows and InvShiftRows TablesTom Musta1-0/+8
This patch adds tables that implement the Advanced Encryption Standard (AES) ShiftRows and InvShiftRows transformations. These are commonly used in instruction models.

2013-07-27aes: Remove unused code (NDEBUG, u16)Stefan Weil1-5/+0
The current code includes assert.h very early (from qemu-common.h), so the definition of NDEBUG was without any effect. In the initial version from 2004, NDEBUG was used to disable the assertions. Those assertions are not in time critical code, so it is no longer reasonable to disable them and the definition of NDEBUG can be removed. Type u16 is also unused and therefore does not need a type definition. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2013-04-13aes: make Td[0-5] and Te[0-5] tables non staticAurelien Jarno1-252/+252
Remove static attribute to Td[0-5] and Te[0-5] tables so that they can be used outside of aes.c. Change their type from u32 to uint32_t, to keep the u32 udef local to aes.c. Prefix them with AES_ so that they do not conflict with other symbols. Reviewed-by: Edgar E.

Move aes.h from include/block to include/qemu to show it can be reused by other subsystems. Cc: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Edgar E.
