Subject: [PATCH 0/2] net: socket: Fix potential spectre v1 gadgets

Hi folks,

This fixes a pair of potential spectre v1 gadgets.

Note that because the speculation window is large, the policy is to stop
the speculative out-of-bounds load and not worry if the attack can be
completed with a dependent load or store[0].
