This patchset adds the 'pcrypt' parallel crypto template. With this template it is possible to process the crypto requests of a transform in parallel without getting request reorder. This is in particular interesting for IPsec. The parallel crypto template is based on a generic parallelization/serialization method. This method uses the remote softirq invocation infrastructure for parallelization and serialization. With this method data objects can be processed in parallel, starting at some given point. After doing some expensive operations in parallel, it is possible to serialize again. The parallelized data objects return after serialization in the order as they were before the parallelization. In the case of IPsec, this makes it possible to run the expensive parts in parallel without getting packet reordering. Changes from v1: - cpu_chainiv is dropped, pcrypt uses eseqiv as it's IV generator now. - Add a xfrm netlink message to be able to choose for pcrypt from userspace. - Use pcrypt just if it is selected from userspace. - Patchset applies to 2.6.30-rc3 Steffen -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
