Subject: Questions about CVE-2016-8660
Date: Thu, 5 Mar 2020 16:30:16 +0800	[thread overview]
Message-ID: <2cb951f9-bd4e-a182-e7d3-6a903ff49535@huawei.com> (raw)

Recently I am studying CVE-2016-8660, in https://seclists.org/oss-sec/2016/q4/118,
it says that this bug is introduced by commit fc0561cefc04 ("xfs: optimise away log forces on timestamp updates for fdatasync").
And in https://patchwork.kernel.org/patch/9363339/#19693745, david correction has nothing to do with this commit,
and is a page lock order bug in the XFS seek hole/data implementation(demsg is in http://people.redhat.com/qcai/tmp/dmesg-sync,
Unfortunately, it is not accessible now, I do not understand why this is a page lock order bug).

Is this CVE solved? Can I see the demsg in other way? thanks.
