Aya Levin a463146e67 net/mlx4: Fix UBSAN warning of signed integer overflow
UBSAN: Undefined behavior in
drivers/net/ethernet/mellanox/mlx4/resource_tracker.c:626:29
signed integer overflow: 1802201963 + 1802201963 cannot be represented
in type 'int'

The union of res_reserved and res_port_rsvd[MLX4_MAX_PORTS] monitors
granting of reserved resources. The grant operation is calculated and
protected, thus both members of the union cannot be negative.  Changed
type of res_reserved and of res_port_rsvd[MLX4_MAX_PORTS] from signed
int to unsigned int, allowing large value.

Fixes: 5a0d0a6161 ("mlx4: Structures and init/teardown for VF resource quotas")

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.
