Gustavo A. R. Silva 119d4350a5 RDMA/core: Use size_{add,sub,mul}() in calls to struct_size() 
[ Upstream commit 81760bedc6 ]

If, for any reason, the open-coded arithmetic causes a wraparound,
the protection that `struct_size()` provides against potential integer
overflows is defeated. Fix this by hardening calls to `struct_size()`
with `size_add()`, `size_sub()` and `size_mul()`.

Fixes: 467f432a52 ("RDMA/core: Split port and device counter sysfs attributes")
Fixes: a4676388e2 ("RDMA/core: Simplify how the gid_attrs sysfs is created")
Fixes: e9dd5daf88 ("IB/umad: Refactor code to use cdev_device_add()")
Fixes: 324e227ea7 ("RDMA/device: Add ib_device_get_by_netdev()")
Fixes: 5aad26a7ea ("IB/core: Use struct_size() in kzalloc()")

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.
