Subject: Re: Apparent serious progressive ext4 data corruption bug in 3.6.3 (and other stable branches?)
Date: Wed, 24 Oct 2012 00:06:21 +0100 [thread overview]
Message-ID: <87bofsn5zm.fsf@spindle.srvr.nix> (raw)
In-Reply-To: <20121023221913.GC28626@thunk.org> (Theodore Ts'o's message of "Tue, 23 Oct 2012 18:19:13 -0400")
On 23 Oct 2012, Theodore Ts'o verbalised:

I note that the patch is in the latest stable releases of 3.4.x and
3.5.x, which are IIRC end-of-lifed. I'd say that if your patch does
indeed fix it, this justifies pushing out new releases of both these
stable kernels with just this patch in, just to make sure people taking
the latest stable kernel from those releases don't eat their
filesystems.
The bug did really quite a lot of damage to my /home fs in only a few
minutes of uptime, given how few files I wrote to it. What it could have
done to a more conventional distro install with everything including
/home on one filesystem, I shudder to think.
(I've posted a note to the LWN thread announcing 3.6.3, just in case
that saves someone's fs.)
