lib: crc32: Greatly shrink CRC combining code

2014-06-25T23:03:59Z

There's no need for a full 32x32 matrix, when rows before the last are just shifted copies of the rows after them. There's still room for improvement (especially on X86 processors with CRC32 and PCLMUL instructions), but this is a large step in the right direction [which is in particular useful for its current user, namely SCTP checksumming over multiple skb frags[] entries, i.e. in IPVS balancing when other CRC32 offloads are not available]. The internal primitive is now called crc32_generic_shift and takes one less argument; the XOR with crc2 is done in inline wrappers.

lib: crc32: add functionality to combine two crc32{, c}s in GF(2)

2013-11-04T04:04:56Z

This patch adds a combinator to merge two or more crc32{,c}s into a new one. This is useful for checksum computations of fragmented skbs that use crc32/crc32c as checksums. The arithmetics for combining both in the GF(2) was taken and slightly modified from zlib. Only passing two crcs is insufficient as two crcs and the length of the second piece is needed for merging. The code is made generic, so that only polynomials need to be passed for crc32_le resp. crc32c_le. Signed-off-by: Daniel Borkmann Cc: linux-kernel@vger.kernel.org Signed-off-by: David S. Miller

[PATCH] crc32: replace bitreverse by bitrev32

2006-12-08T16:28:39Z

This patch replaces bitreverse() by bitrev32. The only users of bitreverse() are crc32 itself and via-velocity. Cc: Jeff Garzik Cc: Matt Domsch Signed-off-by: Akinobu Mita Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[netdrvr] ethernet crc fixes

2003-01-03T11:00:55Z

* ether_crc has always been wrong in 2.5.x. ug. we want bitreverse crc32_le instead * use ether_crc in natsemi

v2.5.1.11 -> v2.5.2

2002-02-05T08:13:33Z

- Matt Domsch: combine common crc32 library - Pete Zaitcev: ymfpci update - Davide Libenzi: scheduler improvements - Al Viro: almost there: "struct block_device *" everywhere - Richard Gooch: devfs cpqarray update, race fix - Rusty Russell: PATH_MAX should include the final '0' count - David Miller: various random updates (mainly net and sparc)
