Subject: [PATCH mptcp-net 0/2] mptcp: options: avoid printing uninit data
Date: Tue, 08 Sep 2026 19:07:10 +0200 [thread overview]
Message-ID: <20260908-mptcp-opt-read-debug-v1-0-b3e74549b6f6@kernel.org> (raw)
When parsing the MPTCP suboptions, some pr_debug() might read and print
uninit values.
That's mostly harmless, but that's also confusing. Fixing that also
avoids some tools to complain about accessing unint data.
So read these fields only if they have been set.
