Re: [PATCH] vsock: preserve child namespace mode on an empty write
From: sashiko-bot@kernel.org
Date: 2026-09-15 11:21:38
__vsock_net_mode_string() returns success without updating new_mode when
the write length is zero. Its caller then reads the uninitialized enum and
may permanently store a stack-derived value in the write-once child mode.
Initialize new_mode from the current child mode so that an empty write is
a no-op.
