The strlen() check at the beginning of iw_cm_map() ensures that devname
and ifname strings are less than destinations to which they are supposed
to be copied. Change strncpy() call to be strcpy(), because we are
protected from overflow. Zero the entire string buffer to avoid copying
uninitialized kernel stack memory to userspace.
This fixes the compilation warning below:
In file included from ./include/linux/dma-mapping.h:6,
from drivers/infiniband/core/iwcm.c:38:
In function _strncpy_,
inlined from _iw_cm_map_ at drivers/infiniband/core/iwcm.c:519:2:
./include/linux/string.h:253:9: warning: ___builtin_strncpy_ specified
bound 32 equals destination size [-Wstringop-truncation]

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.
