[PATCH v6 00/20] osstest: initial FreeBSD support

[PATCH v6 00/20] osstest: initial FreeBSD support

[Roger Pau Monne]

Hello,

This series introduces initial FreeBSD host support to osstest. The
current series allow installing a bare-metal host with FreeBSD and
building FreeBSD on it in order to generate new install media that can
be fed into the installer script.

This is still very limited, since no Xen testing is done on those
hosts, however it sets the base to add a Xen build test for FreeBSD.

Note that it should be quite easy to add more steps to the build
script so that FreeBSD VM images are also generated, that could be
used by osstest.

I've tried to add a detailed commit log at each relevant patch, so not
much more to add here in the cover letter.

The series can also be found on my git repo:

git://xenbits.xen.org/people/royger/osstest.git freebsd_v6

List of patches:

A = Acked
N = New in this version

A 01/20 osstest: make built_stash_file store a path_ runvar
A 02/20 osstest: move known_hosts generation to TestSupport

[PATCH v6 02/20] osstest: move known_hosts generation to TestSupport

[Roger Pau Monne]

This is equivalent to the already existing authorized_keys function,
and generates the contents of the known_hosts file that should be
installed on targets.

[PATCH v6 05/20] osstest: introduce a helper to setup a host to boot using memdisk

[Roger Pau Monne]

The helper allows booting a host from pxelinux using an image
compatible with memdisk.

Note that this requires having a copy of the memdisk binary (provided
as part of pxelinux) in the root of the tftp server.

Deployment note: A copy of the memdisk binary (from syslinux) must be
placed in the root of the tftp server, on Debian this is accomplished
using;

ln -s /usr/lib/syslinux/memdisk /tftp/root/memdisk

Well.  On trying to build something on top of this, I notice that
$ho->{Ident} is completely wrong here.  That, ultimately, is going to
be restype.  But restype must be the fixed value `host'.

And this function `resource_shared_mark_ready' only marks hosts ready
- since it takea $ho.

I propose to send you a followup patch which renames your new
resource_shared_mark_ready to host_shared_mark_ready, and passes
'host' instead of $ho->{Ident}.  Alternatively I can wait for you to
do this, if that would be disruptive to you.

Also `$resource' here is the wrong variable name.  This is actually
the $sharetype (as is evident from jobdb_resource_shared_mark_ready
and what is now executive_resource_shared_mark_ready.  That is a bug
which is introduced in your patch.  Would you like to respin this as
you are about to rebase this onto what is about to become master,
anyway ?

Thanks,
Ian.

[PATCH v6 08/20] osstest: add a FreeBSD host install script

[Roger Pau Monne]

The installation is performed using the bsdinstall tool, which is part
of the FreeBSD base system. The installer image is setup with the
osstest ssh keys and sshd enabled by default, which allows the test
harness to just ssh into the box, create the install config file and
launch the scripted install.

Currently the installation is done with ZFS only, in stripe mode, and
a single disk.

In order to support the FreeBSD installer the setup_netboot_memdisk
helper is used, that allows setting the pxe boot of a host using a
memdisk.

The install script either picks the binary images from the output of a
previous FreeBSD buildjob (yet to be introduced), or from the folder
pointed by freebsd_distpath. This folder should contain the installer
image (install.img) and the compressed install sets (kernel.txz,
base.txz) together with the MANIFEST file that contains the checksums.

Changes since v4:
 - Remove get_sets_path routine and xopts variable.
 - Call resource_shared_mark_ready when the host is ready to be used.

Changes since v3:
 - Use sha256file instead of the sha256sum clu.
 - Shift parameters passed to the lock and copy script, so that
   parameter 0 is ignored.
 - Copy to .tmp and then move the FreeBSD image.
 - Use a single-line find rune to cleanup old images.
 - Add some missing "set -e".
 - Don't check the output of target_cmd_output_root against undefined,
   that's never going to be true.
 - Split the setup_netboot_memdisk helper code into a pre-patch.

Changes since v2:
 - Use sysrc instead of echo to modify rc.conf.

Changes since v1:
 - Use pkg bootstrap instead of pkg update.
 - Use freebsdbuildjob instead of freebsd_buildjob.
 - add "append raw" to the memdisk command line.
 - Use with-lock-ex instead of flock.
 - Use system_checked and an array to hold the locked command to
   execute.
 - Use an array to store the list of possible disk devices.
 - Use target_putfilecontents_root_stash in order to upload the
   install script to the target.
 - Remove the usage of TftpFreeBSDBase.
 - Use target_tftp_prefix in order to get the prefix for the tftp
   target image path.
 - Add a missing linewrap.
 - Replace the split used to get the runvar paths with a regexp.
 - Place the install sets at /root/osstest_sets instead of
   /tmp/osstest_sets.
 - Pick the sets/installer image from the freebsdbuildjob
   path_freebsdist or from the runvar variable freebsd_distpath.
 - Add a comment about which FreeBSD specific inputs the script
   consumes.

[PATCH v6 09/20] osstest: introduce build helpers for FreeBSD

[Roger Pau Monne]

Some steps of the FreeBSD build process need to be done as root, so
introduce some helpers to perform those steps:
buildcmd_stamped_logged_root and target_cmd_build_root. They behave
exactly the same as the non-root counterparts.

[PATCH v6 11/20] osstest: add support for the FreeBSD package manager

[Roger Pau Monne]

FreeBSD support is added to target_install_packages and
target_install_packages_norec, although there's no equivalent to the
--no-install-recommends in the FreeBSD package manager.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
---
Changes since v5:
 - Add prototype for package_install_cmd.
 - Use $ho->{Ident} instead of hardcoding "host" in get_hostflags.

Changes since v4:
 - Unify more code between FreeBSD and Debian: introduce an
   OS-agnostic package_install_cmd to generate the install cmd.

Changes since v3:
 - New in this version.

[PATCH v6 12/20] osstest: introduce a FreeBSD build script

[Roger Pau Monne]

In order to generate the FreeBSD installer image and the install
media.

The install sets are the vanilla ones generated by the 'ftp' release
target.  The installer image is handcrafted based on the filesystem
created by the 'bootonly' target, which is then populated with the ssh
host keys, and setup in order to use the serial console. The other
difference from upstream FreeBSD installer images is that the one
built by osstest uses a ramdisk instead of relying on the installer
media to be somehow attached, either on a CD or USB drive. This is
required in order to boot the image from pxelinux (where no CD or USB
is actually attached to the host, and everything is fetched from
tftp).

Due to the nature of the FreeBSD build, the outputs are different from
what osstest expects from a buildjob, more specifically
path_freebsddist points to a folder that contains the several outputs
form this buildjob.

[PATCH v6 13/20] osstest: add support for runtime_IDENT_hostflags

[Roger Pau Monne]

This is required for FreeBSD, that will need to set some of the
hostflags at runtime. The current IDENT_hostflags will be keep as-is,
and they should only be set at job creation time.

Also introduce a helper to set the runtime hostflags.

Changes since v4:
 - Allow runtime flags to be appended instead of overwritten.

[PATCH v6 14/20] osstest: introduce a script to set the runtime hostflags runvar for FreeBSD jobs

[Roger Pau Monne]

Due to the nature of the FreeBSD install media, which is
self-generated from the ts-freebsd-build script, the hostflags runvar
set to FreeBSD jobs are related to the current version under test.

The following hostflags might need to be fetched from the runvars of a
previous build-$arch-freebsd job:

 - share-build-freebsd-$arch-$hash: the $hash used here is calculated
   from the checksum of the installer image used by this specific job.
   This allows osstest to share FreeBSD build hosts, and be sure the
   exact desired FreeBSD version is used.
 - PropMinVer:Freebsd:$version: $version contains the major FreeBSD
   version under test. This version is obtained from the FreeBSD
   source code used to create the install media.

Note that the share-build-* hostflag is optional, and will only be set
for build jobs.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
---
Changes since v5:
 - Fetch the host idents from the arguments, instead of assuming
   "host" always.
 - Set PropMinVer:Freebsd:<version> instead of freebsd-<version> to
   better cope with FreeBSD version bumps. This should only happen
   every ~2 years.

Changes since v4:
 - Make the share-build- flag optional.

Changes since v3:
 - Make use of the set_runtime_hostflag helper.
 - Make use of the sha256file helper.

Changes since v2:
 - New in this version.

[PATCH v6 15/20] osstest: change the meaning of need_build_host

[Roger Pau Monne]

Make need_build_host store a string instead of a boolean. This is
later going to be expanded to handle the FreeBSD build jobs.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
---
Changes since v5:
 - Use a regsub to set need_build_host.
 - NB: I would prefer to keep the tolower instead of changing the
   procs to -FREEBSD/-LINUX since I don't really like the SHOUTING.

Changes since v4:
 - Fix the usage of the catching-otherwise blocks.

Changes since v3:
 - New in this version (split from patch).

[PATCH v6 16/20] osstest: add support for FreeBSD buildjobs to sg-run-job

[Roger Pau Monne]

Add support and introduce a FreeBSD build job to sg-run-job.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
---
Changes since v5:
 - Add a '+' to the arguments passed to ts-freebsd-set-hostflags, so
   they are hidden from testid.

Changes since v4:
 - Use a switch in allocate-build-host.

Changes since v3:
 - New in this version (split from existing patch).

[PATCH v6 17/20] osstest: introduce a script to create a FreeBSD flight

[Roger Pau Monne]

The logic to create a FreeBSD build job is added to
make-freebsd-flight. This includes creating a FreeBSD build job, and
also testing the output of that build job (by creating another build
job that depends on the output of the first).

Note that the FreeBSD build job needs some input in order to setup a
FreeBSD host, and that can be fetched from different places:

1. Env variable FREEBSD_<arch>_BUILDJOB: use the output from a
previous build-<arch>-freebsd job.

2. Env variables FREEBSD_DIST and FREEBSD_VERSION: set before calling
into make-flight, provide the path to the installer image and sets
folder and the version being installed.

3. Config file FreeBSDDist and FreeBSDVersion: same as 2. except that
they are set on the config file.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>
---
Changes since v5:
 - Append the "freebsd" hostflag, the specific version will be set
   dynamically by the ts-freebsd-set-hostflags script.
 - Use FREEBSD_<arch>_BUILDJOB to set the freebsdbuildjob runvar.
 - Loop around arches, although only amd64 is supported ATM. This
   should make it easier to add more arches later on.
 - Expand README comment to describe the expected layout of the
   FreeBSD install media.

Changes since v4:
 - Convert get_freebsdjob_runvars into set_freebsd_runvars, mimic the
   behavior of set_hostos_runvars.

Changes since v3:
 - Split the sg-run-job code into pre-patches.

Changes since v1:
 - Replace freebsd_buildjob with freebsdbuildjob.
 - Replace FREEBSD_SETS/IMAGE with a single FREEBSD_DIST that points
   to a folder that should contain both things.
 - Document the FreeBSDDist and FreeBSDVersion config file options in
   the README file.

I think we discussed using PropMinVer ?
I'm not sure what the generic versionless "freebsd" hostflag is for.

Please rewrap.  The current width causes wrap damage when quoted.

Aside from those two comments, this LGTM.

Hm, right. I've initially added it to prevent installing on ARM boxes,
but that's already accomplished by the arch- hostflag. Will remove it.

[PATCH v6 18/20] osstest: hook FreeBSD flight into cr-daily-branch

[Roger Pau Monne]

Add the missing pieces so that cr-daily-branch knows how to create a
FreeBSD flight. This has been tested by calling `./cr-daily-branch
freebsd-master`.

Note that there are two missing pieces. The first one is correctly
setting the FREEBSD_<arch>_BUILDJOB environment variable when calling
make-freebsd-flight, without it the installer media will always be
picked from the configuration file. This requires keeping track of
previous FreeBSD successful build jobs, marking them as permanent and
fetching them from the database in order to pass them on the env
variable.

Signed-off-by: Roger Pau Monné <roger.pau@citrix.com>

Changes since v5:
 - Add support for testing multiple FreeBSD branches, default to
   branch master.

Changes since v3:
 - Fix the daily-cron-email-* settings for FreeBSD branch flights.

PUSH_TREE_FREEBSD seems not to be defined.  Have I missed something ?

We don't normally call the osstest output branch for trees which are
managed by someone else, "master".  Maybe we want another name ?
Especially if this is going into xenbits's toplevel - but maybe it
isn't.

Apart from that this looks OK, but of course it probably needs a call
to mg-anoint.

That's added in patch 17/20: "osstest: introduce a script to create a
FreeBSD flight". I guess I should move it here for coherency.

osstest-master, likewise we are going to have osstest-stable/11 if
that looks fine.

Thanks. Would you like me to merge the next patch (the mg-anoint
integration) with this one?

In other trees directly in the xenbits toplevel we call them:
   tested/SOMETHING              (linux-pvops.git)
   xen-tested-master             (libvirt.git)
   osstest/frozen/XENBRANCH      (libvirt.git)

I suggest tested/$branchcore ?

Are you implying that $branchcore might be `stable/11' ?  I don't
think we can have osstest branches with / in...

No, it's easier this way I think.

Yes, that seems fine.

$branchcore might be stable/11, but $branch is going to be stable-11
(no '/'). As you say above osstest already uses
osstest/frozen/XENBRANCH for libvirt, so I assume it's not a problem
to have other output git branches with '/'.

This is rather ugly.  At the very least, can we have a loop over
architectures ?

Can you do this without fallthrough please ?  That is, just make a
seperate case statement.  And why is this so early, and added to the
setting of treeurl ?

I think it would probaby be best to do this after *_REVISION are
calculated, just before ap-fetch-version-baseline-late.  Would that
work ?

No, please don't change this.  Instead I think this should be done in
the section where we do the actual push ?  Or maybe we need another
tracking variable `anoint'.  We need to think about the following
cases:

  OSSTEST_PUSH=false    probably want not to anoint
  $branch.force         I think this should force an anoint
  OLD_REVISON=none      Now forces test, should force anoint

What about supporting

  OSSTEST_ANOINT=false  ?

I think the right approach is probably to add code after $wantpush and
$push are computed, which computes $anoint, in a similar way.

Also I would like you to discuss explicitly (in a comment or commit
message) about whether push or anoint should come first.  If push
comes first then we can end up pushed but not anointed; and, vice
versa.  What are the recovery arrangements from such a failure ?

Thanks,
Ian.

I would rather rely on OSSTEST_ANOINT=false, which could be set
independently of OSSTEST_PUSH. Having anointed != pushed is confusing,
but should not cause issues as long as the anointed version doesn't
contain regressions from the previous version.

>   $branch.force         I think this should force an anoint

Hm, not sure. AFAICT (sorry I couldn't find the documentation about
.force), .force will force a push of the branch, regardless of the
results of the flight.

The problem with this is that osstest might shoot itself in the foot,
and end up with a set of anointed artifacts that doesn't even boot,
thus leaving the FreeBSD flight unable to produce new versions. This
state would then require manual intervention in order to fix.

>   OLD_REVISON=none      Now forces test, should force anoint

I don't think we should anoint if OLD_REVISION=none, because osstest
won't have anything to compare the current result, so it doesn't know
if there are regression or not.

Hm, that's a hard one. I think push should be our primary goal, and as
such we should try to do the push first, so that a failed anoint
doesn't prevent a push.

OTOH, doing a push and failing on anoint doesn't seem that critical,
osstest can still use the oldish anointed artifacts and continue
working, hoping that on the next pass the anoint will succeed.

Let me know if that sounds OK to you, and I will formalize it in a
comment.

Thanks, Roger.

But there might not be a next pass.  When we push, we overwrite the
state information that triggered the run.  So we push first, and the
anoint fails, then we end up in a state where if the input branch
doesn't change, osstest won't run a new flight.

Conversely, if we anoint first: if a flight is anointed, but the
corresponding revision is not pushed, then osstest ought to rerun the
flight and do a further anoint (and hopefully a push).  But this does
mean that osstest might anoint a series of identical outputs,
defeating the point of keeping a few older versions.

A third option would be to push first, but to call mg-anoint and/or
sg-check-tested to figure out whether the pushed revision was anointed
and run the flight unconditionally if not.  An advantage of this is
that if osstest is modified to add an architecture, this check would
automatically fail and a flight would be run to generate the first
"proper" anointed build from the (presumably preseeded by hand) ad-hoc
anointed build.

Ian.

OK, forcing a new flight if the anointed revision doesn't match
OLD_REVISION (regardless of whether OLD_REVISION == NEW_REVISION)
seems like the best option.

I don't think I have any other questions before I send a new version,
would you be fine with me sending only patches [17, 19]?

Also, could you please Ack/NAck patch 10? (it's trivial).

I would still push the whole lot with the updated tags to my repo, but
there's no need to spam the list with the whole series anymore at this
point IMHO.

Thanks, Roger.

Jolly good.

Done.  (PS: sorry)

Right.

Can you please bundle my anointment patches in your git branch ?

Thanks,
Ian.
