crypto: scatterwalk - remove scatterwalk_samebuf()

2018-08-03T10:06:04Z

scatterwalk_samebuf() is never used. Remove it. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: scatterwalk - remove 'chain' argument from scatterwalk_crypto_chain()

2018-08-03T10:06:03Z

All callers pass chain=0 to scatterwalk_crypto_chain(). Remove this unneeded parameter. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: scatterwalk - Inline start/map/done

2016-07-18T09:35:50Z

This patch inlines the functions scatterwalk_start, scatterwalk_map and scatterwalk_done as they're all tiny and mostly used by the block cipher walker. Signed-off-by: Herbert Xu

crypto: scatterwalk - Remove scatterwalk_bytes_sglen

2016-07-18T09:35:48Z

This patch removes the now unused scatterwalk_bytes_sglen. Anyone using this out-of-tree should switch over to sg_nents_for_len. Signed-off-by: Herbert Xu

crypto: replace scatterwalk_sg_chain with sg_chain

crypto: scatterwalk - Add scatterwalk_ffwd helper

2015-05-22T03:25:50Z

This patch adds the scatterwalk_ffwd helper which can create an SG list that starts in the middle of an existing SG list. The new list may either be part of the existing list or be a chain that latches onto part of the existing list. Signed-off-by: Herbert Xu

crypto: replace scatterwalk_sg_next with sg_next

2015-01-26T00:34:22Z

Modify crypto drivers to use the generic SG helper since both of them are equivalent and the one from crypto is redundant. See also: 468577abe37ff7b453a9ac613e0ea155349203ae reverted in b2ab4a57b018aafbba35bff088218f5cc3d2142e Signed-off-by: Cristian Stoica Signed-off-by: Herbert Xu

crypto: api - Move crypto_yield() to algapi.h

2014-06-20T13:26:04Z

It makes no sense for crypto_yield() to be defined in scatterwalk.h , move it into algapi.h as it's an internal function to crypto API. Signed-off-by: Marek Vasut Signed-off-by: Herbert Xu

crypto: scatterwalk - Use sg_chain_ptr on chain entries

2013-12-09T11:58:52Z

Now that scatterwalk_sg_chain sets the chain pointer bit the sg_page call in scatterwalk_sg_next hits a BUG_ON when CONFIG_DEBUG_SG is enabled. Use sg_chain_ptr instead of sg_page on a chain entry. Cc: stable@vger.kernel.org Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu

crypto: scatterwalk - Set the chain pointer indication bit

2013-11-28T14:16:24Z

The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain function to chain two scatterlists, but the chain pointer indication bit is not set. When the resulting scatterlist is used, for example, by sg_nents to count the number of scatterlist entries, a segfault occurs because sg_nents does not follow the chain pointer to the chained scatterlist. Update scatterwalk_sg_chain to set the chain pointer indication bit as is done by the sg_chain function. Cc: stable@vger.kernel.org Signed-off-by: Tom Lendacky Signed-off-by: Herbert Xu
