Subject: [PATCH net 0/2] mptcp: fix warn on bad status
Date: Fri, 12 Dec 2025 13:54:02 +0100 [thread overview]
Message-ID: <20251212-net-mptcp-subflow_data_ready-warn-v1-0-d1f9fd1c36c8@kernel.org> (raw)
Two somewhat related fixes addressing different issues found by
syzkaller, and producing the exact same splat: a WARNING in
subflow_data_ready().
- Patch 1: fallback earlier on simultaneous connections to avoid a
warning. A fix for v5.19.
- Patch 2: ensure context reset on disconnect, also to avoid a similar
warning. A fix for v6.2.
