A port of the Illumos Crypto Framework to a Linux kernel module (found in module/icp). This is needed to do the actual encryption work. We cannot use the Linux kernel's built in crypto api because it is only exported to GPL-licensed modules. Having the ICP also means the crypto code can run on any of the other kernels under OpenZFS. I ended up porting over most of the internals of the framework, which means that porting over other API calls (if we need them) should be fairly easy. Specifically, I have ported over the API functions related to encryption, digests, macs, and crypto templates. The ICP is able to use assembly-accelerated encryption on amd64 machines and AES-NI instructions on Intel chips that support it. There are place-holder directories for similar assembly optimizations for other architectures (although they have not been written).

*
|
|
* This file contains the code for declaring the tables needed to implement
|
|
* AES. The file aesopt.h is assumed to be included before this header file.
|
|
* If there are no global variables, the definitions here can be used to put
|
|
* the AES tables in a structure so that a pointer can then be added to the
|
|
* AES context to pass them to the AES routines that need them. If this
|
|
* facility is used, the calling program has to ensure that this pointer is
|
|
* managed appropriately. In particular, the value of the t_dec(in, it) item
|
|
* in the table structure must be set to zero in order to ensure that the
|
|
* tables are initialised. In practice the three code sequences in aeskey.c
|
|
* that control the calls to aes_init() and the aes_init() routine itself will
|
|
* have to be changed for a specific implementation. If global variables are
|
|
* available it will generally be preferable to use them with the precomputed
|
|
* FIXED_TABLES option that uses static global tables.
|
|
*
|
|
* The following defines can be used to control the way the tables
|
|
* are defined, initialised and used in embedded environments that
|
|
* require special features for these purposes
|
|
*
|
|
* the 't_dec' construction is used to declare fixed table arrays
|
|
* the 't_set' construction is used to set fixed table values
|
|
* the 't_use' construction is used to access fixed table values
|
|
*
|
|
* 256 byte tables:
|
|
*
|
|
* t_xxx(s, box) => forward S box
|
|
* t_xxx(i, box) => inverse S box
|
|
*
|
|
* 256 32-bit word OR 4 x 256 32-bit word tables:
|
|
*
|
|
* t_xxx(f, n) => forward normal round
|
|
* t_xxx(f, l) => forward last round
|
|
* t_xxx(i, n) => inverse normal round
|
|
* t_xxx(i, l) => inverse last round
|
|
* t_xxx(l, s) => key schedule table
|
|
* t_xxx(i, m) => key schedule table
|
|
*
|
|
* Other variables and tables:
|
|
*
|
|
* t_xxx(r, c) => the rcon table

/*
|
|
* OpenSolaris OS modifications
|
|
*
|
|
* 1. Added __cplusplus and _AESTAB_H header guards
|
|
* 2. Added header file sys/types.h
|
|
* 3. Remove code defined for _MSC_VER
|
|
* 4. Changed all variables to "static const"
|
|
* 5. Changed uint_8t and uint_32t to uint8_t and uint32_t
|
|
* 6. Cstyled and hdrchk code
