While working with the hostdev tag and SCSI LUNs, a problem was
discovered with the XML schema (see commit message in patch 4).
This spawned some further corrections to the handling of the
logical unit field throughout libvirt.
This series was split from a single patch, from this feedback:
http://www.redhat.com/archives/libvir-list/2015-June/msg00489.html
Eric Farman (5):
Print SCSI logical unit as a positive integer
Print SCSI logical unit as unsigned integer
Convert SCSI logical unit from int to long long
docs: Fix XML schema handling of LUN address in hostdev tag
docs: Correct typos in scsi hostdev and address elements

New subject: [libvirt] [PATCH 1/5] Print SCSI logical unit as a positive integer
A logical unit address is a positive integer, so it would be wise
to reject any negative inputs.

While we're at it - why not bus and target as well? That's doable in
one patch... I'll adjust this in order
Looking back through history it seems commit id '5c811dce' added this
functionality to domain.conf.c and commit id 'e962a579' added address
parsing for the attach-disk command.
I also peeked at the review cycle of the domain_conf.c change and found
my name, but at the time I didn't notice that we were expecting a non
negative value storing as unsigned, but printing as signed... In my
defense I was newer to the group though ;-)
So, I'll add bus/target as _uip and then adjust the title/commit message
appropriately when I push the changes.

The linux kernel/qemu code have some more confusion in how the bus and
target are printed, but that's certainly not the responsibility of this
patch series. The LUN is always printed as %llu in the other layers of
the stack, so I just wanted to get them in sync.
So yes, I'm fine with cleaning up bus and target in both these patches.
Thanks!

New subject: [libvirt] [PATCH 2/5] Print SCSI logical unit as unsigned integer
The logical unit field is an unsigned integer, we should
use the appropriate substitution when printing it.

Similar to 1/5 - why only adjust unit, adjust bus & target too since
they're incorrect. I will adjust when I push (and change commit message
to reflect that).

New subject: [libvirt] [PATCH 4/5] docs: Fix XML schema handling of LUN address in hostdev tag
Defining a domain with a SCSI disk attached via a hostdev
tag and a source address unit value longer than two digits
causes an error when editing the domain with virsh edit,
even if no changes are made to the domain definition.
The error suggests invalid XML, somewhere:
# virsh edit lmb_guest
error: XML document failed to validate against schema:
Unable to validate doc against /usr/local/share/libvirt/schemas/domain.rng
Extra element devices in interleave
Element domain failed to validate content
The virt-xml-validate tool fails with a similar error:
# virt-xml-validate lmb_guest.xml
Relax-NG validity error : Extra element devices in interleave
lmb_guest.xml:17: element devices: Relax-NG validity error :
Element domain failed to validate content
lmb_guest.xml fails to validate
The hostdev tag requires a source address to be specified,
which includes bus, target, and unit address attributes.
According to the SCSI Architecture Model spec (section
4.9 of SAM-2), a LUN address is 64 bits and thus could be
up to 20 decimal digits long. Unfortunately, the XML
schema limits this string to just two digits. Similarly,
the target field can be up to 32 bits in length, which
would be 10 decimal digits.

...trimmed...
Since the reference unit and target fields are used in
several places in the XML schema, create a separate one
specific for SCSI Logical Units that will permit the
greater length. This permits both the validation utility
and the virsh edit command to succeed when a hostdev
tag is included.

I'm going to add a test as well. It's essentially a copy of
tests/qemuxml2argvdata/qemuxml2argv-hostdev-scsi-virtio-scsi.xml
adjusted to have a larger unit value (it'll be attached)
Ok. If you push it as a separate patch, feel free to add:

New subject: [libvirt] [PATCH 5/5] docs: Correct typos in scsi hostdev and address elements
The type='scsi' parameter of an address element is ignored
if placed within a hostdev section, and rejected by the XML
schema used by virt-xml-validate. Remove it from the doc,
and correct a typo in the remaining address arguments.

I get the value of small patches & agree with the way patches 4 and 5
are split out, but patch 1 and 2 are completely replaced by patch 3 with
a different type. These are pretty straightforward changes, so I'd
suggest squashing patches 1-3 as a single patch that just goes from
signed int --> unsigned long long and has a commit that explains why we
needed to change both size and sign... I see now that it was a v1
comment from John, so I'll leave it to his judgment.
Regardless, code still looks good to me so you can feel free to keep my
reviewed-by tag for the set, whether patches 1-3 are squashed or not.

The recommendation came
from John and since he can push... following it
to get it upstream is ... OK. :-)

I agree with Mat!

Another side info: I will currently not revert your former patch and
apply this patch set on branches devel and rebased but wait until I
update to libvirt v1.3.0!
If you disagree with this approach please let me know.

While I understand the comments regarding the step by step process -
consider bisection when/if something went wrong with these patches in
the future... Was the issue because we parsed a positive integer? Was
the issue because we printed an unsigned value? Was the issue because
we printed a long long unsigned? Easier to revert something smaller and
rework, than have to go through everything.
I've made adjustments in my local branch to add the unsigned for bus and
target, as well as a couple of other adjustments I've noted. I'll give
it a day or so to percolate before pushing though just in case I've
missed something...
Tks -
