New 4.0.2 and 4.1.1 release candidates

New 4.0.2 and 4.1.1 release candidates

[Keir Fraser]

Folks,

New release candidates are tagged in the 4.0 and 4.1 trees:

Tag '4.0.2-rc4' in http://xenbits.xen.org/staging/xen-4.0-testing.hg
 - This is expected to be the final RC for 4.0.2. Please test!

Tag '4.1.1-rc1' in http://xenbits.xen.org/staging/xen-4.1-testing.hg
 - Please test, and also suggest further backports for 4.1.1.

 Thanks,
 Keir

I have made a new '4.0.2-rc5' tag in the above repository, fixing a couple
of minor issues (including build failure on some older gcc versions). This
is the new final RC tag.

The same patches are also applied to the 4.1-testing repo, and will be
rolled into 4.1.1-rc2 in due course.

Is it too late to merge the patch discussed at

	http://lists.xensource.com/archives/html/xen-devel/2011-05/msg00306.html

?

In the email thread you will find the patch and an ack.

Proposal: vif-local

[W. Michael Petullo]

For site-specific reasons, I use the network-route/vif-route scripts. I
have found that we need to maintain a few custom firewall rules in order
to make things operate in an acceptable manner. I'd like to see a place
to put such scripts and any other site-specific setup related to bringing
up a vif. Keeping this separate from vif-route is useful so that the
installed scripts may be kept unmodified.

What I have come up with is vif-local, a script that lives in
/etc/xen/scripts. I modified vif-route to call vif-local right before
it logs "Successful..."

Would it be possible to modify vif-route, vif-bridge, etc. to operate
in this manner? This has been discussed briefly on the list before,
but I had not yet seen a solution.

I think it would be better to be more general and support a vif-post.d
style directory which can contain scripts all of which are called (with
a defined set of paramters/env variables).

Not sure if we want vif-{route,bridge,etc}-post.d or not, perhaps that's
overkill. Using -post.d leaves open the option to add -pre.d in the
future as necessary.

Seems like a reasonable enough idea to me, please send a patch though.

I have attached a patch against Xen 4.1.0 that implements a vif-post.d
system. I only support the Linux hotplug case at this point.

Thanks. I've got a few comments.

The header of "${XEN_SCRIPT_DIR}/vif-post.d/00-vif-local" describes a
command line parameter "(add|remove|online|offline)" but none of the
invocations actually pass one.

I think it would be better to encapsulate the functionality in a
"call_hooks <devtype> <hook> <other args...>" function in
xen-hotplug-common.sh, calling it as "call_hooks vif post ..." rather
than open coding that loop everywhere.

I think generally it is a good idea to have an explicit suffix (e.g.
".hook") for this sort of thing since then you can use *.hook to get the
list of files which saves manually filtering out *~ *.rpmsave *.dpkg-bak
*.disabled-by-admin *.some-random-suffix-intended-to-disable-the-script
etc.

You probably want to quote $f in case some nutter uses a space in the
hook filename.

You don't actually install 00-vif-local but I think that's a good thing
since the default is an empty script so we save a fork/exec by not
running it.

Lastly we need a Signed-off-by per the DCO (section 11 of
http://lwn.net/Articles/139918/) as well as a suitable changelog message
before we can apply any patch.

Thanks,
Ian.

Since the hooks are now sourced they no longer take parameters. It is,
in fact, a shell variable and I have updated the comments.

Please see the attached patch.

Allow for site-specific hooks that will be executed after Xen initializes
a vif. This allows an administrator to specify custom firewall rules or
other special configuration parameters.

This is against 4.1? can you check that it applies to xen-unstable.hg
please, other than that:

I pulled xen-unstable.hg from Mercurial and the patch applied cleanly. The

We don't generally apply patches directly to the stable trees (4.0 and
4.1, at the moment).  We like them to come through xen-unstable first.

When you submitted your patch, you got this reply:

I only backport toolstack patches that I'm requested to by a toolstack
maintainer. Cc'ing Ian Jackson.

(And it's not too late for 4.1.1, assuming the backport is acceptable.)

Keir,

what about all the changes made to xen/common/trace.c up to now?

There are *loads* of them. I don't think so, presumably it's not really all
bug fixes. It's somewhat up to George however.

I think 23173 is a bugfix, but I have never used cpu hotplug.

It fixes a bug introduced by some other post-4.1 patch. The bug is not in
4.1.

It looks like 23091:67632e5cf652 and 23128:4a335f1000ea are fixes to
code changed in 23050:4ebba54b666f, is that correct?  I don't see
anything else that's a candidate for backporting.

Yes, my understanding is that all subsequent changes and fixes to trace.c in
xen-unstable stem from c/s 23050, which is a big feature patch likely
unsuitable for backport to 4.1. So we should put this to bed and backport
nothing.
