Subject: [PATCH net] net: ethtool: correct MAX attribute value for stats
Date: Thu, 8 Jun 2023 09:23:44 -0700 [thread overview]
Message-ID: <20230608162344.1210365-1-kuba@kernel.org> (raw)
When compiling YNL generated code compiler complains about
array-initializer-out-of-bounds. Turns out the MAX value
for STATS_GRP uses the value for STATS.
This may lead to random corruptions in user space (kernel
itself doesn't use this value as it never parses stats).
Fixes: f09ea6fb1272 ("ethtool: add a new command for reading standard stats")
