/*
|
||||
* High-level description of CRC
|
||||
* =============================
|
||||
*
|
||||
* Consider a bit sequence 'bits[1...len]'. Interpet 'bits' as the "message"
|
||||
* polynomial M(x) with coefficients in GF(2) (the field of integers modulo 2),
|
||||
* where the coefficient of 'x^i' is 'bits[len - i]'. Then, compute:
|
||||
*
|
||||
* R(x) = M(x)*x^n mod G(x)
|
||||
*
|
||||
* where G(x) is a selected "generator" polynomial of degree 'n'. The remainder
|
||||
* R(x) is a polynomial of max degree 'n - 1'. The CRC of 'bits' is R(x)
|
||||
* interpeted as a bitstring of length 'n'.
|
||||
*
|
||||
* CRC used in gzip
|
||||
* ================
|
||||
*
|
||||
* In the gzip format (RFC 1952):
|
||||
*
|
||||
* - The bitstring to checksum is formed from the bytes of the uncompressed
|
||||
* data by concatenating the bits from the bytes in order, proceeding
|
||||
* from the low-order bit to the high-order bit within each byte.
|
||||
*
|
||||
* - The generator polynomial G(x) is: x^32 + x^26 + x^23 + x^22 + x^16 +
|
||||
* x^12 + x^11 + x^10 + x^8 + x^7 + x^5 + x^4 + x^2 + x + 1.
|
||||
* Consequently, the CRC length is 32 bits ("CRC-32").
|
||||
*
|
||||
* - The highest order 32 coefficients of M(x)*x^n are inverted.
|
||||
*
|
||||
* - All 32 coefficients of R(x) are inverted.
|
||||
*
|
||||
* The two inversions cause added leading and trailing zero bits to affect the
|
||||
* resulting CRC, whereas with a regular CRC such bits would have no effect on
|
||||
* the CRC.
|
||||
*
|
||||
* Computation and optimizations
|
||||
* =============================
|
||||
*
|
||||
* We can compute R(x) through "long division", maintaining only 32 bits of
|
||||
* state at any given time. Multiplication by 'x' can be implemented as
|
||||
* right-shifting by 1 (assuming the polynomial<=>bitstring mapping where the
|
||||
* highest order bit represents the coefficient of x^0), and both addition and
|
||||
* subtraction can be implemented as bitwise exclusive OR (since we are working
|
||||
* in GF(2)). Here is an unoptimized implementation:
|
||||
*
|
||||
* static u32 crc32_gzip(const u8 *buffer, size_t nbytes)
|
||||
* {
|
||||
* u32 remainder = 0;
|
||||
* const u32 divisor = 0xEDB88320;
|
||||
*
|
||||
* for (size_t i = 0; i < nbytes * 8 + 32; i++) {
|
||||
* int bit;
|
||||
* u32 multiple;
|
||||
*
|
||||
* if (i < nbytes * 8)
|
||||
* bit = (buffer[i / 8] >> (i % 8)) & 1;
|
||||
* else
|
||||
* bit = 0; // one of the 32 appended 0 bits
|
||||
*
|
||||
* if (i < 32) // the first 32 bits are inverted
|
||||
* bit ^= 1;
|
||||
*
|
||||
* if (remainder & 1)
|
||||
* multiple = divisor;
|
||||
* else
|
||||
* multiple = 0;
|
||||
*
|
||||
* remainder >>= 1;
|
||||
* remainder |= (u32)bit << 31;
|
||||
* remainder ^= multiple;
|
||||
* }
|
||||
*
|
||||
* return ~remainder;
|
||||
* }
|
||||
*
|
||||
* In this implementation, the 32-bit integer 'remainder' maintains the
|
||||
* remainder of the currently processed portion of the message (with 32 zero
|
||||
* bits appended) when divided by the generator polynomial. 'remainder' is the
|
||||
* representation of R(x), and 'divisor' is the representation of G(x) excluding
|
||||
* the x^32 coefficient. For each bit to process, we multiply R(x) by 'x^1',
|
||||
* then add 'x^0' if the new bit is a 1. If this causes R(x) to gain a nonzero
|
||||
* x^32 term, then we subtract G(x) from R(x).
|
||||
*
|
||||
* We can speed this up by taking advantage of the fact that XOR is commutative
|
||||
* and associative, so the order in which we combine the inputs into 'remainder'
|
||||
* is unimportant. And since each message bit we add doesn't affect the choice
|
||||
* of 'multiple' until 32 bits later, we need not actually add each message bit
|
||||
* until that point:
|
||||
*
|
||||
* static u32 crc32_gzip(const u8 *buffer, size_t nbytes)
|
||||
* {
|
||||
* u32 remainder = ~0;
|
||||
* const u32 divisor = 0xEDB88320;
|
||||
*
|
||||
* for (size_t i = 0; i < nbytes * 8; i++) {
|
||||
* int bit;
|
||||
* u32 multiple;
|
||||
*
|
||||
* bit = (buffer[i / 8] >> (i % 8)) & 1;
|
||||
* remainder ^= bit;
|
||||
* if (remainder & 1)
|
||||
* multiple = divisor;
|
||||
* else
|
||||
* multiple = 0;
|
||||
* remainder >>= 1;
|
||||
* remainder ^= multiple;
|
||||
* }
|
||||
*
|
||||
* return ~remainder;
|
||||
* }
|
||||
*
|
||||
* With the above implementation we get the effect of 32 appended 0 bits for
|
||||
* free; they never affect the choice of a divisor, nor would they change the
|
||||
* value of 'remainder' if they were to be actually XOR'ed in. And by starting
|
||||
* with a remainder of all 1 bits, we get the effect of complementing the first
|
||||
* 32 message bits.
|
||||
*
|
||||
* The next optimization is to process the input in multi-bit units. Suppose
|
||||
* that we insert the next 'n' message bits into the remainder. Then we get an
|
||||
* intermediate remainder of length '32 + n' bits, and the CRC of the extra 'n'
|
||||
* bits is the amount by which the low 32 bits of the remainder will change as a
|
||||
* result of cancelling out those 'n' bits. Taking n=8 (one byte) and
|
||||
* precomputing a table containing the CRC of each possible byte, we get
|
||||
* crc32_slice1() defined below.
|
||||
*
|
||||
* As a further optimization, we could increase the multi-bit unit size to 16.
|
||||
* However, that is inefficient because the table size explodes from 256 entries
|
||||
* (1024 bytes) to 65536 entries (262144 bytes), which wastes memory and won't
|
||||
* fit in L1 cache on typical processors.
|
||||
*
|
||||
* However, we can actually process 4 bytes at a time using 4 different tables
|
||||
* with 256 entries each. Logically, we form a 64-bit intermediate remainder
|
||||
* and cancel out the high 32 bits in 8-bit chunks. Bits 32-39 are cancelled
|
||||
* out by the CRC of those bits, whereas bits 40-47 are be cancelled out by the
|
||||
* CRC of those bits with 8 zero bits appended, and so on. This method is
|
||||
* implemented in crc32_slice4(), defined below.
|
||||
*
|
||||
* In crc32_slice8(), this method is extended to 8 bytes at a time. The
|
||||
* intermediate remainder (which we never actually store explicitly) is 96 bits.
