[ Upstream commit8027bc0307] If user passed an interface option longer than 15 characters, then device.ifr_name and hwtstamp.ifr_name became non-null-terminated strings. The compiler warned about this: timestamping.c:353:2: warning: ‘strncpy’ specified bound 16 equals \ destination size [-Wstringop-truncation] 353 | strncpy(device.ifr_name, interface, sizeof(device.ifr_name)); Fixes:cb9eff0978("net: new user space API for time stamping of incoming and outgoing packets") Signed-off-by: Tanner Love <tannerlove@google.com> Acked-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
