-Subject: net/smc: fix smc clc failed issue when netdevice not in init_net
-
-From: Albert Huang <huangjie.albert@bytedance.com>
-
-[ Upstream commit c68681ae46eaaa1640b52fe366d21a93b2185df5 ]
-
-If the netdevice is within a container and communicates externally
-through network technologies such as VxLAN, we won't be able to find
-routing information in the init_net namespace. To address this issue,
-we need to add a struct net parameter to the smc_ib_find_route function.
-This allow us to locate the routing information within the corresponding
-net namespace, ensuring the correct completion of the SMC CLC interaction.

-Subject: net/smc: support smc release version negotiation in clc handshake
-
-From: Guangguan Wang <guangguan.wang@linux.alibaba.com>
-
-[ Upstream commit 1e700948c9db0d09f691f715e8f4b947e51e35b5 ]
-
-Support smc release version negotiation in clc handshake based on
-SMC v2, where no negotiation process for different releases, but
-for different versions. The latest smc release version was updated
-to v2.1. And currently there are two release versions of SMCv2, v2.0
-and v2.1. In the release version negotiation, client sends the preferred
-release version by CLC Proposal Message, server makes decision for which
-release version to use based on the client preferred release version and
-self-supported release version (here choose the minimum release version
-of the client preferred and server latest supported), then the decision
-returns to client by CLC Accept Message. Client confirms the decision by
-CLC Confirm Message.
-
-Client Server
- Proposal(preferred release version)
- ------------------------------------>
-
- Accept(accpeted release version)
- min(client preferred, server latest supported)
- <------------------------------------
-
- Confirm(accpeted release version)

-

-
-[ Upstream commit 6ac1e6563f5915cd38b6bc6a8b26964b2252f751 ]
-
-Support SMC v2.x features validate for SMC v2.1. This is the frame
-code for SMC v2.x features validate, and will take effects only when
-the negotiated release version is v2.1 or later.
-
-For Server, v2.x features' validation should be done in smc_clc_srv_
-v2x_features_validate when receiving v2.1 or later CLC Proposal Message,
-such as max conns, max links negotiation, the decision of the final
-value of max conns and max links should be made in this function.
-And final check for server when receiving v2.1 or later CLC Confirm
-Message should be done in smc_clc_v2x_features_confirm_check.
-
-For client, v2.x features' validation should be done in smc_clc_clnt_
-v2x_features_validate when receiving v2.1 or later CLC Accept Message,
-for example, the decision to accpt the accepted value or to decline
-should be made in this function.
