This is XSA-115, and isn't something new in 4.15 vs 4.14.  (I think?)

> + - xenstore can now be live-updated on a running system.

This needs to be very clear that it is tech preview.  It does not
currently work cleanly if a malicious VM deliberately holds a
transaction open.

XSA-115 went public during the 4.15 development window.

So on the one hand, it’s certainly effort that happened during the window, which it would be good to highlight.   On the other hand, it was backported to all security supported trees (?), so it’s not something you need to update to 4.15 to get.

Honestly not sure the best thing to suggest here.

OK, I’ll add (tech preview) at the end.

Thanks,

We either want all XSAs discussed, or none of them.  Possibly as simple
as "the following XSAs {...} where developed and released" ?

I recall Lars making this part of the release notes in the past.

albeit I again wonder if this isn't too small / niche a change to warrant an
entry here.

I don’t think that’s true.  The vast majority of our XSAs are, “Make it work the way everyone already thought it worked”.  This is a user-visible change in behavior.

Like I said, I do see your point; not sure what I think the best thing is to do.

> I recall Lars making this part of the release notes in the past.

Lars included an XSA report on the xenproject.org download page for point releases, not full releases; something I’ve carried on doing.  e.g.:

https://xenproject.org/downloads/xen-project-archives/xen-project-4-13-series/xen-project-4-13-3/

At least it’s a user-visible change this time. :-)

It was in a list of potential items passed to my by Ian; at any rate I’ll let him have the final say (when he comes back Tuesday).
