commit 8c5a50e8e7ad812a62f7ccf28d9a5e74fddf3000 upstream.
The bfa driver has a number of real issues with string termination that gcc-8 now points out:

In most cases, this can be addressed by correctly calling strlcpy and strlcat instead of strncpy/strncat, with the size of the destination buffer as the last argument.
For consistency, I'm changing the other callers of strncpy() in this driver the same way.
