Hello Steve,
Doesn't this feature require provider support? It seems like this patch really doesn't do anything yet.
It is a fix for the client registration logic. When the user space port mapper is restarted, the IWPM_PREV_REG_CLIENTs send their mapping information to the port mapper, afterwards they are allowed to send remove mapping requests and they should be.
If you look at the remove mapping request logic, you see that only registered clients are allowed to make a remove mapping request.
In other words, without this fix there are just registered and non-registered clients. IWPM_PREV_REG_CLIENTs are handled like non-registered clients, so their remove mapping requests aren't allowed to go the port mapper, when the rdma application closes the connections in use.
No provider support is necessary.
Thanks for clarifying.
Steve.
