[PATCH v2 0/4] net: Use strlcpy() for ethtool::get_strings

[Florian Fainelli]

Hi all,

After turning on KASAN on one of my systems, I started getting lots of out of
bounds errors while fetching a given port's statistics, and indeed using
memcpy() is unsafe for copying strings which have not been declared as an array
of ETH_GSTRING_LEN bytes, so let's use strlcpy() instead. This allows the best
of both worlds: we still keep the efficient memory usage of variably sized
strings, but we don't copy more than we need to.

Changes in v2:
- dropped the 3 other patches that were not necessary
- use strlcpy() instead of strncpy()
