------------------------------------------------------
From: Peter Hurley <peter@xxxxxxxxxxxxxxxxxx>
Subject: console: fix console name size mismatch
commit 6ae9200f2cab7 ("enlarge console.name") increased the storage for
the console name to 16 bytes, but not the corresponding struct
console_cmdline::name storage. Console names longer than 8 bytes cause
read beyond end-of-string and failure to match console; I'm not sure if
there are other unexpected consequences.
