Subject: [PATCH 0/1] One More NTFS Fuzzing Fix
Date: Sun,  1 Jun 2025 10:52:21 -0500	[thread overview]
Message-ID: <20250601155222.21934-1-adhamilt@gmail.com> (raw)

I took one last pass at my attempts at ad-hoc fuzzing of NTFS
with the goal of improving coverage and letting the fuzzer run
for a while. After rebuilding afl++ to allow larger file inputs
that are more representative of real NTFS file systems, it was
uncovered that my last fix to address NTFS test regressions
left a possible access violation in find_attr.

This fixes the last remaining fuzzing issue uncovered.

Confirmed that NTFS test cases still pass.
