This is the 2nd iteration of this patchset incorporating danpb's
suggestions. Along with a couple other minor things, the type attribute
is again a required attribute, and netcf support will be omitted in
the build unless you have netcf-devel-0.1.3 or greater. Since there is
no netcf-devel-0.1.3 yet, I tested this by changing the appropriate
strings to 0.1.2. 0.1.3 will be released "soon" (I want to try and get
IPv6 address reporting in before lutter cuts another release). I just
wanted to get the patches to the list early to get some visual review
in case I screwed up anything new ;-)
Note that (unless you're building/installing netcf from the head of
git) if you try to fake out the version of netcf yourself you'll get
runtime errors from virInterfaceGetXMLDesc (iface-dumpxml) due to
there being no "type" attribute in the interface xml.

New subject: [libvirt] [PATCH 1/3] Make startmode optional in toplevel interface definitions.
From: Laine Stump <laine(a)laine.org>
The minimal XML returned from ncf_if_xml_state() doesn't contain this
attribute (which makes no sense in the case of reporting current
status of the interface), and it was preventing it from passing
through the parse/format step.

Okay, I usually prefer when enum numbering is not shuffled in patches,
but in that case that should have no consequence, so ACK,
I'm pushing this, thanks !

New subject: [libvirt] [PATCH 2/3] Support reporting live interface IP/netmask.
From: Laine Stump <laine(a)laine.org>
This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
live interface info will be returned in the XML (in particular, the IP
address(es) and netmask(s) will be retrieved by querying the interface
directly, rather than reporting what's in the config file). The
backend of this is in netcf's ncf_if_xml_state() function.
Note that after this patch is applied, netcf support will be omitted
from the build unless you have netcf-devel-0.1.3 or better installed.

New subject: [libvirt] [PATCH 2/3] Support reporting live interface IP/netmask.
On Fri, Oct 16, 2009 at 10:56:18AM -0400, laine(a)laine.org wrote:
From: Laine Stump <laine(a)laine.org>
This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
live interface info will be returned in the XML (in particular, the IP
address(es) and netmask(s) will be retrieved by querying the interface
directly, rather than reporting what's in the config file). The
backend of this is in netcf's ncf_if_xml_state() function.
Okay, looks fine, applied.
Note that after this patch is applied, netcf support will be omitted
from the build unless you have netcf-devel-0.1.3 or better installed.
yup, it's not worth messing the code to handle older releases at this
point I guess. The only problem will be with people using F-12 or
versions based on netcf 0.1.x x < 3 willing to recompile a newer version
and loosing the interface functionality.

I don't think the error reporting is quite right here. At the time of
declaration you initialize 'ret = 0', so those two error cases inside
the for loop which break out will end up returning 0. I think it is
better to initialize 'ret = -1', change the 'break' to 'goto
error',
and after the for loop put 'ret = 0' to mark success.

It's hard to be sure we aren't leaking there too. On second reading
this looks okay because def is passed by the caller and we are storing
the data there.

Hum, we don't check there that an ipv6/4 protocol is not defined
multiple time. Maybe this could be slightly refactored to search
for 1 protocol node with type IPv4 and the one protocol node for type
Ipv6 something like
v4 = virXPathNode(conn, "./protocol[@family = 'ipv4']", ctxt)
v6 = virXPathNode(conn, "./protocol[@family = 'ipv6']", ctxt)
and drop the loop.
But current code works too, just does less checking IMHO.
I think we need to patch the previous leak.
But the main problem I faced when running the regression tests.
I had installed netcf-0.1.3 and a number of thing just break with
this patch. For example when libvirtd exits in the
"testing with corrupted config" libvirtd it just segfaults:
Starting program: /u/veillard/libvirt/daemon/libvirtd --config=in1.conf
[...]
Program received signal SIGSEGV, Segmentation fault.
drv_close (ncf=0x7f0740) at drv_initscripts.c:511
511 xsltFreeStylesheet(ncf->driver->get);
(gdb) p ncf->driver
$2 = (struct driver *) 0x0
(gdb) p *ncf
$3 = {ref = 1, root = 0x7f0780 "/",
data_dir = 0x7ffff77626b8 "/usr/share/netcf", errcode = NETCF_NOERROR,
errdetails = 0x0, driver = 0x0, debug = 0}
(gdb)
IMHO it's a bug in netcf since it should protect against acessing
uninitialized fields. The libvirtd side is:
/* open netcf */
if (ncf_init(&driverState->netcf, NULL) != 0)
{
/* what error to report? */
goto netcf_error;
}
conn->interfacePrivateData = driverState;
return 0;
netcf_error:
if (driverState->netcf)
{
ncf_close(driverState->netcf);
}
maybe if ncf_init() failed we should not call ncf_close()
but we can see that there is at least a string in that driver which need
to be deallocated.
I ran the test on Fedora 11 updated with netcf-0.1.3:
What I don't understand is why that patch affecting only
src/conf/interface_conf.[ch] is the one breaking this...
Hum, I reverted that patch and still get the error, maybe it's just
the netcf update ! I will try to clarify where things went wrong.
I also noted that the interface XML parsing regression tests also failed
which might be normal though since no reg test was updated.

Okay, I modified netcf to incorporate the patch below to avoid the
crash, but I still get a ton of regression tests failures on F-11 +
0.1.3 + your 3 patches when running make check as non-root.
If I checkout master without your patches in the same environment
make check passes fine.
So I'm postponing commiting your patches until we have an additional
patch fixing the regressions I see,
sorry,

Hum ... shouldn't def be freed too there ???
Yes, you are correct. It will be fixed in the redo.

It's hard to be sure we aren't leaking there too. On second reading
this looks okay because def is passed by the caller and we are storing
the data there.
Correct. The caller will clean up if there's a failure.
Hum, we don't check there that an ipv6/4 protocol is not
defined
multiple time. Maybe this could be slightly refactored to search
for 1 protocol node with type IPv4 and the one protocol node for type
Ipv6 something like
v4 = virXPathNode(conn, "./protocol[@family = 'ipv4']", ctxt)
v6 = virXPathNode(conn, "./protocol[@family = 'ipv6']", ctxt)
Yeah, I can do that.
In the meantime, I've sent a netcf patch that gets vlan xml passing the
libvirt parse, but I'm having trouble finding the info for bridges and
bonds either in sysfs or netlink, and my brain is finished for the day.
Basically, for a bridge to pass, we need the name of the physical
interface, and for bond to pass, we need an miimon node with freq
property, or an arpmode node with interval and target properties, in
addition to the names of the physical interfaces. I'm not finding those
anywhere.

Yeah, I can do that.
Now that I'm actually doing it, I'm having doubts about this. Making
this change leads to many other changes (mostly making the code simpler,
but still changed lines are changed lines, and could lead to new bugs).
More important, though, I notice that if we do it this way we lose the
ability to report an error if someone botches up the family of a
protocol - with this new method of parsing it will just be ignored; with
the current setup in my patch, an error will be reported if there's a
protocol that is missing family, or has family set to anything other
than "ipv4" or "ipv6".
Would it maybe be better to still cycle through all the protocol nodes
in the document with a loop as currently, but report an error if a
particular protocol family is encountered a 2nd time?
If so, can/should that be submitted as a separate patch, rather than
trying to get it into the patch that's already working? (If that's the
case, I'll clean up and resend the patches sooner rather than later).

Ah right, I didn't though about that side of the checking

yup,

Let's just make a cleanup patch on top of the current one !

New subject: [libvirt] [PATCH] Fix virInterfaceIpDefPtr leak during virInterfaceIpDefFree().
This is the only update to the patchset already sent. All other problems
were either in netcf code, or will be cleaned up later.
A patch has been sent to netcf-devel which, when applied, allows make
check of libvirt plus the patch series to complete with no errors.
There is still one issue, affecting bond interfaces, which is not
revealed by make check. I'll describe that in a separate email.

Okay, applied !
I have the single netcf patch to avoid a crash, but when running the
regression tests I still see:
9) Interface XML-2-XML bond
... FAILED
10) Interface XML-2-XML bond-arp
... FAILED
FAIL: interfacexml2xmltest
=====================
12 of 43 tests failed
=====================

So what am I missing ?

all 5 patches are now pushed,
thanks !

New subject: [libvirt] [PATCH 0/3] IPv6 / multi address / report live config in virInterface
The related patch is now available on the netcf-devel mailing list,
making it possible to review this set ;-)
On 10/16/2009 10:56 AM, laine(a)laine.org wrote:
This is the 2nd iteration of this patchset incorporating danpb's
suggestions. Along with a couple other minor things, the type attribute
is again a required attribute, and netcf support will be omitted in
the build unless you have netcf-devel-0.1.3 or greater. Since there is
no netcf-devel-0.1.3 yet, I tested this by changing the appropriate
strings to 0.1.2. 0.1.3 will be released "soon" (I want to try and get
IPv6 address reporting in before lutter cuts another release). I just
wanted to get the patches to the list early to get some visual review
in case I screwed up anything new ;-)
Note that (unless you're building/installing netcf from the head of
git) if you try to fake out the version of netcf yourself you'll get
runtime errors from virInterfaceGetXMLDesc (iface-dumpxml) due to
there being no "type" attribute in the interface xml.
