Subject: [dpdk-dev] [PATCH 1/4] regex/mlx5: fix size of setup constants
Date: Tue, 1 Jun 2021 10:11:19 +0300	[thread overview]
Message-ID: <20210601071122.1612432-1-michaelba@nvidia.com> (raw)

The constant representing the size of the metadata is defined as a
unsigned int variable with 32-bit.
Similarly the constant representing the maximal output is also defined
as a unsigned int variable with 32-bit.

There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that
expects an expression of type size_t (64 bits, unsigned).

Change the size of the above constants to 64-bit.

Fixes: 30d604bb1504 ("regex/mlx5: fix type of setup constants")
