Philippe,
I hear from other sources that you earlier have qualified this one as
"incomplete".
I am of course aware that this one, just like my own patch, is just a
mitigation and not a complete correction of the erroneous calculation.
Or did you have anything else in mind?
Any news on this one? It would be nice to get the CVE fixed for 7.0 ?
Thomas
The ball is currently with John Snow, as I understand it.
The concern is that this fix may not take the driver back to a consistent
state, so that we may have other problems later.
Maybe Philippe can chip in with a comment here?
John, Philippe, any ideas how to move this forward?
Thomas
The ball is indeed in my court. I need to audit this properly and get
the patch re-applied, and get tests passing.
As a personal favor: Could you please ping me on IRC tomorrow about
this? (Well, later today, for you.)
