Parameters

atadev	ATA device
atacmd	ATA command

Return values

atacmd ATA command

Parameters

atacmd	ATA command
atacmd	ATA command

Return values

priv	Private data

Parameters

table	AES lookup table
stride	AES row shift stride
in	AES input state
offset	Output byte offset (after [Inv]ShiftRows)

Return values

product Product of matrix column with S(input byte)

Note that the specified offset is not the offset of the input byte; it is the offset of the output byte which corresponds to the input byte. This output byte offset is used to calculate both the input byte offset and to select the appropriate matric column.

With a compile-time constant offset, this function will optimise down to a single "movzbl" (to extract the input byte) and will generate a single x86 memory reference expression which can then be used directly within a single "xorl" instruction.

Parameters

table	AES lookup table
stride	AES row shift stride
in	AES input state
key	AES round key
column	Column index

Return values

output Output column value

Parameters

table	AES lookup table
stride	AES row shift stride
in	AES input state
out	AES output state
key	AES round key
in	AES input state
out	AES output state
key	Round keys
rounds	Number of rounds (must be odd)

As with aes_encrypt_rounds(), this function is deliberately marked as non-inlinable.

This function could potentially use the same binary code as is used for encryption. To compensate for the difference between ShiftRows and InvShiftRows, half of the input byte offsets would have to be modifiable at runtime (half by an offset of +4/-4, half by an offset of -4/+4 for ShiftRows/InvShiftRows). This can be accomplished in x86 assembly within the number of available registers, but GCC's register allocator struggles to do so, resulting in a significant performance decrease due to registers being spilled to the stack. We therefore use two separate but very similar binary functions based on the same C source.
