ipv4: prevent potential spectre v1 gadget in fib_metrics_match()
[ Upstream commit 5e9398a26a92fc402d82ce1f97cc67d832527da0 ]
if (!type)
continue;
if (type > RTAX_MAX)
return false;
...
fi_val = fi->fib_metrics->metrics[type - 1];
@type being used as an array index, we need to prevent
cpu speculation or risk leaking kernel memory content.
Fixes: 5f9ae3d9e7e4 ("ipv4: do metrics match when looking up and deleting a route")
