The following behavior difference was reported between rsockets and

when remote end is suddenly closed, recv() waiting on it receives
tcp/ip = ECONNRESET error
rsockets = 0 value
Update rrecv() to return ECONNRESET if no data is available
From: Sean Hefty sean.he...@intel.com
Standard sockets allows an application to call listen() multiple

When the keepalive time of an rsocket is updated, the

Extend XRC support to user space through libibverbs. Because XRC requires
new verbs and extensions to existing verbs, we first introduce a generic
mechanism for extending verbs in a backward compatible manner. XRC support
is built on top
From: Sean Hefty sean.he...@intel.com
XRC introduces several new concepts and structures, one of
which is the XRC domain.
XRC domains: xrcd's are a type of protection domain used to
associate shared receive queues with xrc queue pairs. Since
xrcd are meant to be shared among multiple processes
don't see that ABI 3 was in a release).

XRC queue pairs: xrc defines two new types of QPs. The
initiator, or send-side, xrc qp behaves similar to a send-
only RC qp. xrc send qp's are managed through the existing
QP functions. The send_wr structure is extended in a back-
wards compatible way
From: Sean Hefty sean.he...@intel.com
XRC receive QPs are shareable across multiple processes. Allow
any process with access to the xrc domain to open an existing
QP. After opening the QP, the process will receive events
related to the QP and be able to modify the QP.

XRC support requires the use of a new type of SRQ.
XRC shared receive queues: xrc srq's are similar to normal
srq's, except that they are bound to an xrcd, rather
than to a protection domain. Based on the current spec
and implementation, they are only
