<p class="MsoNormal">Hello libfabric users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve hit another stumbling block related to the netdir provider. If I understand the api correctly, when providing hints for mode of “FI_CONTEXT|FI_CONTEXT2”, if the corresponding bits are cleared in the returned fi_info struct, then there
is no requirement for providing a fi_context/fi_context2 struct ahead of any context used by the application.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I am seeing when invoking fi_sendv / fi_recvv is that it is, in fact, using context for internal purposes. The context the application provides is overwritten during the function execution and differs after the call returns.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If I provide an fi_context2 struct ahead of the application context, then things appear to behave as expected.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So, I’m assuming that I’ve stumbled upon a bug here.<o:p></o:p></p>
