Subject: Early 4.1.1 release for image corruption fixes?
Date: Fri, 25 Oct 2019 16:29:15 +0200 [thread overview]
Message-ID: <20191025142915.GG7275@localhost.localdomain> (raw)
Hi,
the QEMU 4.1.0 release has two problems that can easily cause image
corruption with any qcow2 images (no special configuration needed to
trigger the bugs):
1. A locking bug in the qcow2 code. I just sent a pull request that
includes the fix for this. The important patch there is:
'qcow2: Fix corruption bug in qcow2_detect_metadata_preallocation()'
2. A kernel bug in the XFS driver that became visible by new I/O
patterns the qcow2 implementation started to use in 4.1. Max is
currently working on a workaround for this.
The Planning/4.1 wiki page tells me that a 4.1.1 release is planned for
end of November, which isn't too far, but I was wondering if want to
have a stable release even earlier, right after the fixes for both
problems are in.
Peter, if we haven't made a decision until then, maybe discussing this
is an agenda item for QEMU Summit, too.
Kevin
