Subject: [144/146] xen mmu: fix a race window causing leave_mm BUG()
Date: Wed, 01 Jun 2011 17:01:20 +0900 [thread overview]
Message-ID: <20110601080509.970969185@blue.kroah.org> (raw)
In-Reply-To: <20110601080606.GA522@kroah.com>
2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------
From: "Tian, Kevin" <kevin.tian@intel.com>
commit 7899891c7d161752f29abcc9bc0a9c6c3a3af26c upstream.
There's a race window in xen_drop_mm_ref, where remote cpu may exit
dirty bitmap between the check on this cpu and the point where remote
cpu handles drop request. So in drop_other_mm_ref we need check
whether TLB state is still lazy before calling into leave_mm. This
bug is rarely observed in earlier kernel, but exaggerated by the
commit 831d52bc153971b70e64eccfbed2b232394f22f8
("x86, mm: avoid possible bogus tlb entries by clearing prev mm_cpumask after switching mm")
which clears bitmap after changing the TLB state. the call trace is as below:
