preparing for 4.3.2 and 4.2.4

preparing for 4.3.2 and 4.2.4

[Jan Beulich]

Aiming at a release in late January or early February, I'd like to cut
RC1s later this or early next week.

Please indicate any bug fixes that so far may have been missed
in the backports already done.

Thanks, Jan

Looking through the XenServer patch queue on top of stable-4.3

All of these are suggestions for "might be useful to take", rather than
"strictly bugfixes"

I applied all of them to 4.3 and all but the first one to 4.2 (the
first one would require a backport to be done first).

All I'm aware of is

  9.1.14

(that's the date they went into staging)

  2d03be65d5c50053fec4a5fa1d691972e5d953c9
  libxl: Auto-assign NIC devids in initiate_domain_create

  1671cdeac7da663fb2963f3e587fa279dcd0238b
  tools/libxc: Correct read_exact() error messages

But Ian C probably has a nearly-disjoint view of bugfixes which have
gone into staging and could do with backporting.

I'm afraid I've not really been paying attention to things at that
level, sorry :-/

I do not see:


commit 3dbab7a8bf4bef1bb2967cb3a8c7ed2146482ab3


in any 4.2 or 4.3 tree.  As Andrew Cooper said:

Considering that this is only debugging code, I did not view this as
important enough to backport without explicit request.
Furthermore, it hadn't passed the push gate yet when I collected
the most recent batch of backports.

I just now added it to my list of pending backports.

As an aside: It would have helped (read: saved me some time) if you
had also reproduced the title of the commit instead of just the commit
ID. See Andrew's response to the original mail of this thread for an
example (the precise form doesn't matter, the conveyed information
does).
