In order to process the data incrementally, adiantum needs see the source data twice. This patch series adds support for such algorithms in lskcipher including adaptations to algif_skcipher. For now this capability isn't actually exported completely through algif_skcipher. That is, if the source data is too large to be fed at once through an SG list the operation will fail with ENOSYS. As a future extension, the incremental processing can be extended through algif_skcipher (and perhaps even algif_aead). However, I'd like to see some real uses for it before adding this complexity. For example, one valid use-case would be some hardware that directly supported such incremental processing. In addition to converting adiantum, the underlying chacha algorithm is also converted over to lskcipher. The algorithms cts + xts have been converted too to ensure that the tailsize mechanism works properly for them. While doing this the parameters for cts + xts have been modified so that blocksize is now 1. This entails changing the paramters of all drivers that support cts and/or xts.
