Do random linear codes satisfy the smooth min-entropy condition with high probability?
Ascertain whether a random linear outer code C ⊆ F_q^n (q a power of 2) of rate ε satisfies, with high probability, the per-codeword smoothed min-entropy property H_∞^{\bar{c}_η ε}(D_c) ≥ (1 − \bar{c}_γ)·log q for all nonzero c ∈ C, which would imply via Theorem 6 that C ∘ C approaches the GV bound.

It is not clear (to us) whether a random linear code satisfies the min-entropy condition of Theorem 6 with high probability (if it did, it would give an alternate proof of Theorem 4).
