Subject: [PATCH 10/11] hornet: scripts: harden scripts to handle trailing whitespace
Date: Wed, 27 May 2026 20:08:19 -0700	[thread overview]
Message-ID: <20260528030915.2654994-11-bboscaccy@linux.microsoft.com> (raw)
In-Reply-To: <20260528030915.2654994-1-bboscaccy@linux.microsoft.com>

Trailing whitespace after the semicolon in the header files may have
caused the binary extracted payload to be corrupted due to a missing
anchor.
