* crypto: engine - Introduce the block request crypto engine frameworkBaolin Wang2016-02-011-0/+70
| | | | | | | | | | | | | | | | | | | Now block cipher engines need to implement and maintain their own queue/thread for processing requests, moreover currently helpers provided for only the queue itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they don't help with the mechanics of driving the hardware (things like running the request immediately, DMA map it or providing a thread to process the queue in) even though a lot of that code really shouldn't vary that much from device to device. Thus this patch provides a mechanism for pushing requests to the hardware as it becomes free that drivers could use. And this framework is patterned on the SPI code and has worked out well there.

| | | | | | | | | | While converting ecryptfs over to skcipher I found that it needs to pick a default key size if one isn't given.

This fixes a problem that the system is cool, while the fan devices are left running on full speed after boot, if fan device is registered after thermal zone device.

And since the step_wise governor is the only one that uses trends, so it's the only thermal governor that needs to be updated.

However, once the header (envelope) is written to the socket, our peer learns data_len and sets itself to expect at least data_len bytes to follow front or front+middle. If ceph_msg_revoke() is called while the messenger is sending message's data portion, anything we send after that call is counted by the OSD towards the now revoked message's data portion. The effects vary, the most common one is the eventual hang - higher layers get stuck waiting for the reply to the message that was sent out after ceph_msg_revoke() returned and treated by the OSD as a bunch of data bytes. This is what Matt ran into. (2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs is wrong. If ceph_msg_revoke() is called before the tag is sent out or while the messenger is sending the header, we will get a connection reset, either due to a bad tag (0 is not a valid tag) or a bad header CRC, which kind of defeats the purpose of revoke. Currently the kernel client refuses to work with header CRCs disabled, but that will likely change in the future, making this even worse. (3) con->out_skip is not reset on connection reset, leading to one or more spurious connection resets if we happen to get a real one between con->out_skip is set in ceph_msg_revoke() and before it's cleared in write_partial_skip(). Fixing (1) and (3) is trivial. The idea behind fixing (2) is to never zero the tag or the header, i.e. send out tag+header regardless of when ceph_msg_revoke() is called. That way the header is always correct, no unnecessary resets are induced and revoke stands ready for disabled CRCs. Since ceph_msg_revoke() rips out con->out_msg, introduce a new "message out temp" and copy the header into it before sending.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the user changes the Address Vector(AV) in the modify QP, he provides an SL. This SL should be translated to Ethernet Priority by taking the 3 LSB bits, and modify the QP's TIS according to this Ethernet priority.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Raw Packet QP is composed of RQ and SQ, the IB QP's state is derived from the sub-objects. Therefore we need to query each one of the sub-objects, and decide on the IB QP's state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RoCEv2 packets are sent over IP/UDP protocols. The mlx4 driver uses a type of RAW QP to send packets for QP1 and therefore needs to build the network headers below BTH in software. This patch adds option to build QP1 packets with IP and UDP headers if RoCEv2 is requested. Signed-off-by: Moni Shoua <monis@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
