git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 Pull crypto fix from Herbert Xu: "This fixes a hash corruption bug in the marvell driver" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: marvell - Copy IVDIG before launching partial DMA ahash requests
2016-12-16crypto: marvell - Copy IVDIG before launching partial DMA ahash requestsRomain Perier
Currently, inner IV/DIGEST data are only copied once into the hash engines and not set explicitly before launching a request that is not a first frag. This is an issue especially when multiple ahash reqs are computed in parallel or chained with cipher request, as the state of the request being computed is not updated into the hash engine. It leads to non-deterministic corrupted digest results.

2016-12-16crypto: add virtio-crypto driverGonglei
This patch introduces virtio-crypto driver for Linux Kernel. The virtio crypto device is a virtual cryptography device as well as a kind of virtual hardware accelerator for virtual machines. The encryption anddecryption requests are placed in the data queue and are ultimately handled by thebackend crypto accelerators. The second queue is the control queue used to create or destroy sessions for symmetric algorithms and will control some advanced features in the future. The virtio crypto device provides the following cryptoservices: CIPHER, MAC, HASH, and AEAD. For more information about virtio-crypto device, please see: http://qemu-project.org/Features/VirtioCrypto CC: Michael S.

All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

This reverts commit 66d2e2028091a074aa1290d2eeda5ddb1a6c329c. Quoting from Russell's findings: https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg21136.html [quote] Okay, I've re-tested, using a different way of measuring, because using openssl speed is impractical for off-loaded engines. I've decided to use this way to measure the performance: dd if=/dev/zero bs=1048576 count=128 | /usr/bin/time openssl dgst -md5 For the threaded IRQs case gives: 0.05user 2.74system 0:05.30elapsed 52%CPU (0avgtext+0avgdata 2400maxresident)k 0.06user 2.52system 0:05.18elapsed 49%CPU (0avgtext+0avgdata 2404maxresident)k 0.12user 2.60system 0:05.61elapsed 48%CPU (0avgtext+0avgdata 2460maxresident)k => 5.36s => 25.0MB/s and the tasklet case: 0.08user 2.53system 0:04.83elapsed 54%CPU (0avgtext+0avgdata 2468maxresident)k 0.09user 2.47system 0:05.16elapsed 49%CPU (0avgtext+0avgdata 2368maxresident)k 0.10user 2.51system 0:04.87elapsed 53%CPU (0avgtext+0avgdata 2460maxresident)k => 4.95 => 27.1MB/s which corresponds to an 8% slowdown for the threaded IRQ case. So, tasklets are indeed faster than threaded IRQs. [...] I think I've proven from the above that this patch needs to be reverted due to the performance regression, and that there _is_ most definitely a deterimental effect of switching from tasklets to threaded IRQs.
