2017-03-23cryptodev: fix asserting single queueHalil Pasic1-2/+0
We already check for queues == 1 in cryptodev_builtin_init and when that is not true raise an error. But before that error is reported the assertion in cryptodev_builtin_cleanup kicks in (because object is being finalized and freed). Let's remove assert(queues == 1) form cryptodev_builtin_cleanup as it does only harm and no good.

2017-03-23cryptodev: setiv only when really needLongpeng(Mike)1-4/+6
ECB mode cipher doesn't need IV, if we setiv for it then qemu crypto API would report "Expected IV size 0 not **", so we should setiv only when the cipher algos really need. Signed-off-by: Longpeng(Mike) <longpeng2@huawei.com> Signed-off-by: Gonglei <arei.gonglei@huawei.com>
2017-01-10cryptodev: wrap the ready flagGonglei1-0/+4
The ready flag should be set by the children of cryptodev backend interface. Warp the setter/getter functions for it. Signed-off-by: Gonglei <arei.gonglei@huawei.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2016-12-24cryptodev: add 3des-ede supportLongpeng(Mike)1-0/+12
This patch add 3des-ede support for cryptodev. However this is effective only when backend using libgcrypt/nettle, because cipher-builtin doesn't support 3des-ede yet. Signed-off-by: Longpeng(Mike) <longpeng2@huawei.com> Signed-off-by: Gonglei <arei.gonglei@huawei.com>
2016-12-24cryptodev: remove single-DES support in cryptodevLongpeng(Mike)1-4/+0
Single-DES is obsolete and it's broken/useless for decades, we should remove it in cryptodev, as suggested by Daniel. Guest who wants to use this obsolete cipher alg will use its built-in implementation instead. Signed-off-by: Longpeng(Mike) <longpeng2@huawei.com> Reviewed-by: Daniel P.

2016-12-24cryptodev: fix the check of aes algorithmLongpeng(Mike)1-14/+33
As the key length of xts(aes) is different with other mode of aes, so we should check specially in cryptodev_builtin_get_aes_algo, if it is xts mode. Signed-off-by: Longpeng(Mike) <longpeng2@huawei.com> Reviewed-by: Gonglei <arei.gonglei@huawei.com> Signed-off-by: Gonglei <arei.gonglei@huawei.com>
2016-10-30cryptodev: introduce a new cryptodev backendGonglei1-0/+361
The new cryptodev backend named cryptodev-builtin, which realized by QEMU cipher APIs. These APIs can be backed by either nettle or gcrypt. Signed-off-by: Gonglei <arei.gonglei@huawei.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
