When one calls to rdma_get_cm_event, he gets a structure of the
rdma_cm_event.
In this structure there are 2 attributes which i want to discuss about:
* private_data
* private_data_len
It seems that when one side send to the other private data, the private
data is correct
(i mean that the attribute private data points to a memory buffer with
the expected data)
but the private_data_len has a fixed size (depend on the ucma function
which was called).
1) Is this is the expected behavior?
Yes - there's no way for the receiving side of an IB CM message to know
how many bytes of private data are valid in the REQ, REP, etc.
2) can you please add entry to the man pages of this function to clarify
this expected
content of those attributes?
I will update the man pages. Thanks.
- Sean
