Steve Wise d53ec8af56 RDMA/iwcm: Don't copy past the end of dev_name() string
We now use dev_name(&ib_device->dev) instead of ib_device->name in iwpm
messages.  The name field in struct device is a const char *, where as
ib_device->name is a char array of size IB_DEVICE_NAME_MAX, and it is
pre-initialized to zeros.

Since iw_cm_map() was using memcpy() to copy in the device name, and
copying IWPM_DEVNAME_SIZE bytes, it ends up copying past the end of the
source device name string and copying random bytes.  This results in iwpmd
failing the REGISTER_PID request from iwcm.  Thus port mapping is broken.

Validate the device and if names, and use strncpy() to inialize the entire
message field.

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.
