The statesize is used to determine the maximum size for saved ahash context. In some cases, this can be much larger than what is currently allocated for it, for example omap-sham driver uses a buffer size of PAGE_SIZE. Increase the statesize to accommodate this.

Nack. The exported state is supposed to consist of the actual hash state, plus at most one block worth of unhashed data. It's limited so that we can store it on the stack. So no I'm not taking this patch. -- Email: Herbert Xu [off-list ref] Home Page: http://gondor.apana.org.au/~herbert/ PGP Key: http://gondor.apana.org.au/~herbert/pubkey.txt
