Bob Pearson e7f0b9ab8b RDMA/rxe: Fix skb lifetime in rxe_rcv_mcast_pkt()
[ Upstream commit e7ec96fc7932f48a6d6cdd05bf82004a1a04285b ]

The changes referenced below replaced sbk_clone)_ by taking additional
references, passing the skb along and then freeing the skb. This
deleted the packets before they could be processed and additionally
passed bad data in each packet. Since pkt is stored in skb->cb
changing pkt->qp changed it for all the packets.

Replace skb_get() by sbk_clone() in rxe_rcv_mcast_pkt() for cases where
multiple QPs are receiving multicast packets on the same address.

Delete kfree_skb() because the packets need to live until they have been
processed by each QP. They are freed later.

Fixes: 86af617641 ("IB/rxe: remove unnecessary skb_clone")
Fixes: fe896ceb57 ("IB/rxe: replace refcount_inc with skb_get")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
