Illumos Crypto Port module added to enable native encryption in zfs

Browse Source 
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).

* suggestions made by him for which I am most grateful.
*
* An AES implementation for AMD64 processors using the YASM assembler. This
* implementation provides only encryption, decryption and hence requires key
* scheduling support in C. It uses 8k bytes of tables but its encryption and
* decryption performance is very close to that obtained using large tables.
* It can use either MS Windows or Gnu/Linux/OpenSolaris OS calling conventions,
* which are as follows:
* ms windows gnu/linux/opensolaris os
*
* in_blk rcx rdi
* out_blk rdx rsi
* context (cx) r8 rdx
*
* preserved rsi - + rbx, rbp, rsp, r12, r13, r14 & r15
* registers rdi - on both
*
* destroyed - rsi + rax, rcx, rdx, r8, r9, r10 & r11
* registers - rdi on both
*
* The convention used here is that for gnu/linux/opensolaris os.
*
* This code provides the standard AES block size (128 bits, 16 bytes) and the
* three standard AES key sizes (128, 192 and 256 bits). It has the same call
* interface as my C implementation. It uses the Microsoft C AMD64 calling
* conventions in which the three parameters are placed in rcx, rdx and r8
* respectively. The rbx, rsi, rdi, rbp and r12..r15 registers are preserved.
*
* OpenSolaris Note:
* Modified to use GNU/Linux/Solaris calling conventions.
* That is parameters are placed in rdi, rsi, rdx, and rcx, respectively.
*
* AES_RETURN aes_encrypt(const unsigned char in_blk[],
* unsigned char out_blk[], const aes_encrypt_ctx cx[1])/
*
* AES_RETURN aes_decrypt(const unsigned char in_blk[],
* unsigned char out_blk[], const aes_decrypt_ctx cx[1])/
*
* AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],

/*
* The encryption key schedule has the following in memory layout where N is the
* number of rounds (10, 12 or 14):
*
* lo: | input key (round 0) | / each round is four 32-bit words
* | encryption round 1 |
* | encryption round 2 |
* ....
* | encryption round N-1 |
* hi: | encryption round N |
*
* The decryption key schedule is normally set up so that it has the same
* layout as above by actually reversing the order of the encryption key
* schedule in memory (this happens when AES_REV_DKS is set):
*
* lo: | decryption round 0 | = | encryption round N |
* | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
* | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
* .... ....
* | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
* hi: | decryption round N | = | input key (round 0) |
*
* with rounds except the first and last modified using inv_mix_column()
* But if AES_REV_DKS is NOT set the order of keys is left as it is for
* encryption so that it has to be accessed in reverse when used for
* decryption (although the inverse mix column modifications are done)
*
* lo: | decryption round 0 | = | input key (round 0) |
* | decryption round 1 | = INV_MIX_COL[ | encryption round 1 | ]
* | decryption round 2 | = INV_MIX_COL[ | encryption round 2 | ]
* .... ....
* | decryption round N-1 | = INV_MIX_COL[ | encryption round N-1 | ]
* hi: | decryption round N | = | encryption round N |
*
* This layout is faster when the assembler key scheduling provided here
* is used.

* ---------------------------------------------------------------------------
* OpenSolaris OS modifications
*
* This source originates from Brian Gladman file aes_amd64.asm
* in http://fp.gladman.plus.com/AES/aes-src-04-03-08.zip
* with these changes:
*
* 1. Removed MS Windows-specific code within DLL_EXPORT, _SEH_, and
* !__GNUC__ ifdefs. Also removed ENCRYPTION, DECRYPTION,
* AES_128, AES_192, AES_256, AES_VAR ifdefs.
*
* 2. Translate yasm/nasm %define and .macro definitions to cpp(1) #define
*
* 3. Translate yasm/nasm %ifdef/%ifndef to cpp(1) #ifdef
*
* 4. Translate Intel/yasm/nasm syntax to ATT/OpenSolaris as(1) syntax
* (operands reversed, literals prefixed with "$", registers prefixed with "%",
* and "[register+offset]", addressing changed to "offset(register)",
* parenthesis in constant expressions "()" changed to square brackets "[]",
* "." removed from local (numeric) labels, and other changes.
* Examples:
* Intel/yasm/nasm Syntax ATT/OpenSolaris Syntax
* mov rax,(4*20h) mov $[4*0x20],%rax
* mov rax,[ebx+20h] mov 0x20(%ebx),%rax
* lea rax,[ebx+ecx] lea (%ebx,%ecx),%rax
* sub rax,[ebx+ecx*4-20h] sub -0x20(%ebx,%ecx,4),%rax
*
* 5. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
* /usr/include/sys/asm_linkage.h, lint(1B) guards, and dummy C function
* definitions for lint.
*
* 6. Renamed functions and reordered parameters to match OpenSolaris:
* Original Gladman interface:
* int aes_encrypt(const unsigned char *in,
* unsigned char *out, const aes_encrypt_ctx cx[1])/
* int aes_decrypt(const unsigned char *in,
* unsigned char *out, const aes_encrypt_ctx cx[1])/
* Note: aes_encrypt_ctx contains ks, a 60 element array of uint32_t,
* and a union type, inf., containing inf.l, a uint32_t and
* inf.b, a 4-element array of uint32_t. Only b[0] in the array (aka "l") is
* used and contains the key schedule length * 16 where key schedule length is
* 10, 12, or 14 bytes.
*
* OpenSolaris OS interface:
* void aes_encrypt_amd64(const aes_ks_t *ks, int Nr,
* const uint32_t pt[4], uint32_t ct[4])/
* void aes_decrypt_amd64(const aes_ks_t *ks, int Nr,
* const uint32_t pt[4], uint32_t ct[4])/
* typedef union {uint64_t ks64[(MAX_AES_NR + 1) * 4]/
* uint32_t ks32[(MAX_AES_NR + 1) * 4]/ } aes_ks_t/
* Note: ks is the AES key schedule, Nr is number of rounds, pt is plain text,
* ct is crypto text, and MAX_AES_NR is 14.
* For the x86 64-bit architecture, OpenSolaris OS uses ks32 instead of ks64.

*
* Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD)
* instructions that are going to be introduced in the next generation
* of Intel processor, as of 2009. These instructions enable fast and
* secure data encryption and decryption, using the Advanced Encryption
* Standard (AES), defined by FIPS Publication number 197. The
* architecture introduces six instructions that offer full hardware
* support for AES. Four of them support high performance data
* encryption and decryption, and the other two instructions support
* the AES key expansion procedure.

* OpenSolaris OS modifications
*
* This source originates as files aes-intel.S and eng_aesni_asm.pl, in
* patches sent sent Dec. 9, 2008 and Dec. 24, 2008, respectively, by
* Huang Ying of Intel to the openssl-dev mailing list under the subject
* of "Add support to Intel AES-NI instruction set for x86_64 platform".
*
* This OpenSolaris version has these major changes from the original source:
*
* 1. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
* /usr/include/sys/asm_linkage.h, lint(1B) guards, and dummy C function
* definitions for lint.
*
* 2. Formatted code, added comments, and added #includes and #defines.
*
* 3. If bit CR0.TS is set, clear and set the TS bit, after and before
* calling kpreempt_disable() and kpreempt_enable().
* If the TS bit is not set, Save and restore %xmm registers at the beginning
* and end of function calls (%xmm* registers are not saved and restored by
* during kernel thread preemption).
*
* 4. Renamed functions, reordered parameters, and changed return value
* to match OpenSolaris:
*
* OpenSSL interface:
* int intel_AES_set_encrypt_key(const unsigned char *userKey,
* const int bits, AES_KEY *key);
* int intel_AES_set_decrypt_key(const unsigned char *userKey,
* const int bits, AES_KEY *key);
* Return values for above are non-zero on error, 0 on success.
*
* void intel_AES_encrypt(const unsigned char *in, unsigned char *out,
* const AES_KEY *key);
* void intel_AES_decrypt(const unsigned char *in, unsigned char *out,
* const AES_KEY *key);
* typedef struct aes_key_st {
* unsigned int rd_key[4 *(AES_MAXNR + 1)];
* int rounds;
* unsigned int pad[3];
* } AES_KEY;
* Note: AES_LONG is undefined (that is, Intel uses 32-bit key schedules
* (ks32) instead of 64-bit (ks64).
* Number of rounds (aka round count) is at offset 240 of AES_KEY.
*
* OpenSolaris OS interface (#ifdefs removed for readability):
* int rijndael_key_setup_dec_intel(uint32_t rk[],
* const uint32_t cipherKey[], uint64_t keyBits);
* int rijndael_key_setup_enc_intel(uint32_t rk[],
* const uint32_t cipherKey[], uint64_t keyBits);
* Return values for above are 0 on error, number of rounds on success.
*
* void aes_encrypt_intel(const aes_ks_t *ks, int Nr,
* const uint32_t pt[4], uint32_t ct[4]);
* void aes_decrypt_intel(const aes_ks_t *ks, int Nr,
* const uint32_t pt[4], uint32_t ct[4]);
* typedef union {uint64_t ks64[(MAX_AES_NR + 1) * 4];
* uint32_t ks32[(MAX_AES_NR + 1) * 4]; } aes_ks_t;
*
* typedef union {
* uint32_t ks32[((MAX_AES_NR) + 1) * (MAX_AES_NB)];
* } aes_ks_t;
* typedef struct aes_key {
* aes_ks_t encr_ks, decr_ks;
* long double align128;
* int flags, nr, type;
* } aes_key_t;
*
* Note: ks is the AES key schedule, Nr is number of rounds, pt is plain text,
* ct is crypto text, and MAX_AES_NR is 14.
* For the x86 64-bit architecture, OpenSolaris OS uses ks32 instead of ks64.
*
* Note2: aes_ks_t must be aligned on a 0 mod 128 byte boundary.

*
* This file contains the compilation options for AES (Rijndael) and code
* that is common across encryption, key scheduling and table generation.
*
* OPERATION
*
* These source code files implement the AES algorithm Rijndael designed by
* Joan Daemen and Vincent Rijmen. This version is designed for the standard
* block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
* and 32 bytes).
*
* This version is designed for flexibility and speed using operations on
* 32-bit words rather than operations on bytes. It can be compiled with
* either big or little endian internal byte order but is faster when the
* native byte order for the processor is used.
*
* THE CIPHER INTERFACE
*
* The cipher interface is implemented as an array of bytes in which lower
* AES bit sequence indexes map to higher numeric significance within bytes.
*/

* 5. Undefined VIA_ACE_POSSIBLE and ASSUME_VIA_ACE_PRESENT
* 6. Changed uint_8t and uint_32t to uint8_t and uint32_t
* 7. Defined aes_sw32 as htonl() for byte swapping
* 8. Cstyled and hdrchk code

/*
* 1. BYTE ORDER WITHIN 32 BIT WORDS
*
* The fundamental data processing units in Rijndael are 8-bit bytes. The
* input, output and key input are all enumerated arrays of bytes in which
* bytes are numbered starting at zero and increasing to one less than the
* number of bytes in the array in question. This enumeration is only used
* for naming bytes and does not imply any adjacency or order relationship
* from one byte to another. When these inputs and outputs are considered
* as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
* byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
* In this implementation bits are numbered from 0 to 7 starting at the
* numerically least significant end of each byte. Bit n represents 2^n.
*
* However, Rijndael can be implemented more efficiently using 32-bit
* words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
* into word[n]. While in principle these bytes can be assembled into words
* in any positions, this implementation only supports the two formats in
* which bytes in adjacent positions within words also have adjacent byte
* numbers. This order is called big-endian if the lowest numbered bytes
* in words have the highest numeric significance and little-endian if the
* opposite applies.
*
* This code can work in either order irrespective of the order used by the
* machine on which it runs. Normally the internal byte order will be set
* to the order of the processor on which the code is to be run but this
* define can be used to reverse this in special situations
*
* WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
* This define will hence be redefined later (in section 4) if necessary

* words. On some machines this will always be possible but there may

* lead to memory access errors when such 32-bit word accesses are not
* properly aligned. The option SAFE_IO avoids such problems but will
* often be slower on those machines that support misaligned access
* (especially so if care is taken to align the input and output byte
* arrays on 32-bit word boundaries). If SAFE_IO is not defined it is

*
* 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

* ====================================================================
* OpenSolaris OS modifications
*
* This source originates as file galois_hash_asm.c from
* Intel Corporation dated September 21, 2009.
*
* This OpenSolaris version has these major changes from the original source:
*
* 1. Added OpenSolaris ENTRY_NP/SET_SIZE macros from
* /usr/include/sys/asm_linkage.h, lint(1B) guards, and a dummy C function
* definition for lint.
*
* 2. Formatted code, added comments, and added #includes and #defines.
*
* 3. If bit CR0.TS is set, clear and set the TS bit, after and before
* calling kpreempt_disable() and kpreempt_enable().
* If the TS bit is not set, Save and restore %xmm registers at the beginning
* and end of function calls (%xmm* registers are not saved and restored by
* during kernel thread preemption).
*
* 4. Removed code to perform hashing. This is already done with C macro
* GHASH in gcm.c. For better performance, this removed code should be
* reintegrated in the future to replace the C GHASH macro.
*
* 5. Added code to byte swap 16-byte input and output.
*
* 6. Folded in comments from the original C source with embedded assembly
* (SB_w_shift_xor.c)
*
* 7. Renamed function and reordered parameters to match OpenSolaris:
* Intel interface:
* void galois_hash_asm(unsigned char *hk, unsigned char *s,
* unsigned char *d, int length)
* OpenSolaris OS interface:
* void gcm_mul_pclmulqdq(uint64_t *x_in, uint64_t *y, uint64_t *res);

/*
* Changes made to the original Illumos Crypto Layer for the ICP:
*
* Several changes were needed to allow the Illumos Crypto Layer
* to work in the Linux kernel. Almost all of the changes fall into
* one of the following categories:
*
* 1) Moving the syntax to the C90: This was mostly a matter of
* changing func() definitions to func(void). In a few cases,
* initializations of structs with unions needed to have brackets
* added.
*
* 2) Changes to allow userspace compilation: The ICP is meant to be
* compiled and used in both userspace and kernel space (for ztest and
* libzfs), so the _KERNEL macros did not make sense anymore. For the
* same reason, many header includes were also changed to use
* sys/zfs_context.h
*
* 3) Moving to a statically compiled architecture: At some point in
* the future it may make sense to have encryption algorithms that are
* loadable into the ICP at runtime via separate kernel modules.
* However, considering that this code will probably not see much use
* outside of zfs and zfs encryption only requires aes and sha256
* algorithms it seemed like more trouble than it was worth to port over
* Illumos's kernel module structure to a Linux kernel module. In
* addition, The Illumos code related to keeping track of kernel modules
* is very much tied to the Illumos OS and proved difficult to port to
* Linux. Therefore, the structure of the ICP was simplified to work
* statically and several pieces of code responsible for keeping track
* of Illumos kernel modules were removed and simplified. All module
* initialization and destruction is now called in this file during
* Linux kernel module loading and unloading.
*
* 4) Adding destructors: The Illumos Crypto Layer is built into
* the Illumos kernel and is not meant to be unloaded. Some destructors
* were added to allow the ICP to be unloaded without leaking
* structures.
*
* 5) Removing CRYPTO_DATA_MBLK related structures and code:
* crypto_data_t can have 3 formats, CRYPTO_DATA_RAW, CRYPTO_DATA_UIO,
* and CRYPTO_DATA_MBLK. ZFS only requires the first 2 formats, as the
* last one is related to streamed data. To simplify the port, code
* related to this format was removed.
*
* 6) Changes for architecture specific code: Some changes were needed
* to make architecture specific assembly compile. The biggest change
* here was to functions related to detecting CPU capabilities for amd64.
* The Illumos Crypto Layer used called into the Illumos kernel's API
* to discover these. They have been converted to instead use the
* 'cpuid' instruction as per the Intel spec. In addition, references to
* the sun4u' and sparc architectures have been removed so that these
* will use the generic implementation.
*
* 7) Removing sha384 and sha512 code: The sha code was actually very
* wasy to port. However, the generic sha384 and sha512 code actually
* exceeds the stack size on arm and powerpc architectures. In an effort
* to remove warnings, this code was removed.
*
* 8) Change large allocations from kmem_alloc() to vmem_alloc(): In
* testing the ICP with the ZFS encryption code, a few allocations were
* found that could potentially be very large. These caused the SPL to
* throw warnings and so they were changed to use vmem_alloc().
*
* 9) Makefiles: Makefiles were added that would work with the existing
* ZFS Makefiles.

/*
* mod_hash: flexible hash table implementation.
*
* This is a reasonably fast, reasonably flexible hash table implementation
* which features pluggable hash algorithms to support storing arbitrary keys
* and values. It is designed to handle small (< 100,000 items) amounts of
* data. The hash uses chaining to resolve collisions, and does not feature a
* mechanism to grow the hash. Care must be taken to pick nchains to be large
* enough for the application at hand, or lots of time will be wasted searching
* hash chains.
*
* The client of the hash is required to supply a number of items to support
* the various hash functions:
*
* - Destructor functions for the key and value being hashed.
* A destructor is responsible for freeing an object when the hash
* table is no longer storing it. Since keys and values can be of
* arbitrary type, separate destructors for keys & values are used.
* These may be mod_hash_null_keydtor and mod_hash_null_valdtor if no
* destructor is needed for either a key or value.
*
* - A hashing algorithm which returns a uint_t representing a hash index
* The number returned need _not_ be between 0 and nchains. The mod_hash
* code will take care of doing that. The second argument (after the
* key) to the hashing function is a void * that represents
* hash_alg_data-- this is provided so that the hashing algrorithm can
* maintain some state across calls, or keep algorithm-specific
* constants associated with the hash table.
*
* A pointer-hashing and a string-hashing algorithm are supplied in
* this file.
*
* - A key comparator (a la qsort).
* This is used when searching the hash chain. The key comparator
* determines if two keys match. It should follow the return value
* semantics of strcmp.
*
* string and pointer comparators are supplied in this file.
*
* mod_hash_create_strhash() and mod_hash_create_ptrhash() provide good
* examples of how to create a customized hash table.
*
* Basic hash operations:
*
* mod_hash_create_strhash(name, nchains, dtor),
* create a hash using strings as keys.
* NOTE: This create a hash which automatically cleans up the string
* values it is given for keys.
*
* mod_hash_create_ptrhash(name, nchains, dtor, key_elem_size):
* create a hash using pointers as keys.
*
* mod_hash_create_extended(name, nchains, kdtor, vdtor,
* hash_alg, hash_alg_data,
* keycmp, sleep)
* create a customized hash table.
*
* mod_hash_destroy_hash(hash):
* destroy the given hash table, calling the key and value destructors
* on each key-value pair stored in the hash.
*
* mod_hash_insert(hash, key, val):
* place a key, value pair into the given hash.
* duplicate keys are rejected.
*
* mod_hash_insert_reserve(hash, key, val, handle):
* place a key, value pair into the given hash, using handle to indicate
* the reserved storage for the pair. (no memory allocation is needed
