crypto: scatterwalk - Add support for calculating number of SG elements

2013-08-21T11:27:58Z

Crypto layer only passes nbytes to encrypt but in omap-aes driver we need to know number of SG elements to pass to dmaengine slave API. We add function for the same to scatterwalk library. Signed-off-by: Joel Fernandes Signed-off-by: Herbert Xu

crypto: scatterwalk - Fix scatterwalk_done() test

2010-05-19T04:06:29Z

We are done with the scattergather entry when the walk offset goes past sg->offset + sg->length, not when it crosses a page boundary. There is a similarly queer test in the second half of scatterwalk_pagedone() that probably needs some scrutiny. Signed-off-by: David S. Miller Signed-off-by: Herbert Xu

crypto: scatterwalk - Avoid flush_dcache_page on slab pages

2009-02-09T03:30:25Z

It's illegal to call flush_dcache_page on slab pages on a number of architectures. So this patch avoids doing so if PageSlab is true. In future we can move the flush_dcache_page call to those page cache users that actually need it. Reported-by: David S. Miller Signed-off-by: Herbert Xu

[CRYPTO] scatterwalk: Handle zero nbytes in scatterwalk_map_and_copy

2008-01-10T21:16:54Z

It's better to return silently than crash and burn when someone feeds us a zero length. In particular the null digest algorithm when used as part of authenc will do that to us. Signed-off-by: Herbert Xu

[CRYPTO] scatterwalk: Restore custom sg chaining for now

2008-01-10T21:16:33Z

Unfortunately the generic chaining hasn't been ported to all architectures yet, and notably not s390. So this patch restores the chainging that we've been using previously which does work everywhere. Signed-off-by: Herbert Xu

[CRYPTO] scatterwalk: Move scatterwalk.h to linux/crypto

2008-01-10T21:16:32Z

The scatterwalk infrastructure is used by algorithms so it needs to move out of crypto for future users that may live in drivers/crypto or asm/*/crypto. Signed-off-by: Herbert Xu

[CRYPTO] scatterwalk: Use generic scatterlist chaining

2008-01-10T21:16:14Z

This patch converts the crypto scatterwalk code to use the generic scatterlist chaining rather the version specific to crypto. Signed-off-by: Herbert Xu

[SG] Update crypto/ to sg helpers

crypto: don't pollute the global namespace with sg_next()

2007-10-16T09:07:09Z

It's a subsystem function, prefix it as such. Acked-by: Herbert Xu Signed-off-by: Jens Axboe
