James Smart 13bc6bda6a scsi: lpfc: Fix illegal memory access on Abort IOCBs
[ Upstream commit e1364711359f3ced054bda9920477c8bf93b74c5 ]

In devloss timer handler and in backend calls to terminate remote port I/O,
there is logic to walk through all active IOCBs and validate them to
potentially trigger an abort request. This logic is causing illegal memory
accesses which leads to a crash. Abort IOCBs, which may be on the list, do
not have an associated lpfc_io_buf struct. The driver is trying to map an
lpfc_io_buf struct on the IOCB and which results in a bogus address thus
the issue.

Fix by skipping over ABORT IOCBs (CLOSE IOCBs are ABORTS that don't send
ABTS) in the IOCB scan logic.

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.
