This patch adds three utility functions that operate on virNetDevVPortProfile objects. * virNetDevVPortProfileCheckComplete() - verifies that all attributes required for the type of the given virtport are specified. * virNetDevVPortProfileCheckNoExtras() - verifies that there are no attributes specified which are inappropriate for the type of the given virtport. * virNetDevVPortProfileMerge3() - merges 3 virtports into a single, newly allocated virtport. If any attributes are specified in more than one of the three sources, and do not exactly match, an error is logged and the function fails. These new functions depend on new fields in the virNetDevVPortProfile object that keep track of whether or not each attribute was specified. Since the higher level parse function doesn't yet set those fields, these functions are not actually usable yet (but that's okay, because they also aren't yet used - all of that functionality comes in a later patch.) Note that these three functions return 0 on success and -1 on failure. This may seem odd for the first two Check functions, since they could also easily return true/false, but since they actually log an error when the requested condition isn't met (and should result in a failure of the calling function), I thought 0/-1 was more appropriate. --- src/libvirt_private.syms | 3 + src/util/virnetdevvportprofile.c | 313 +++++++++++++++++++++++++++++++++++++++ src/util/virnetdevvportprofile.h | 17 ++- 3 files changed, 332 insertions(+), 1 deletion(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index c023dbf..89fb1f4 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -1427,8 +1427,11 @@ virNetDevVethDelete; # virnetdevvportprofile.h virNetDevVPortProfileAssociate; +virNetDevVPortProfileCheckComplete; +virNetDevVPortProfileCheckNoExtras; virNetDevVPortProfileDisassociate; virNetDevVPortProfileEqual; +virNetDevVPortProfileMerge3; virNetDevVPortProfileOpTypeFromString; virNetDevVPortProfileOpTypeToString; diff --git a/src/util/virnetdevvportprofile.c b/src/util/virnetdevvportprofile.c index 6db04f7..e686fd9 100644 --- a/src/util/virnetdevvportprofile.c +++ b/src/util/virnetdevvportprofile.c @@ -120,6 +120,319 @@ virNetDevVPortProfileEqual(virNetDevVPortProfilePtr a, virNetDevVPortProfilePtr return true; } +/* virNetDevVPortProfileCheckComplete() checks that all attributes + * required for the type of virtport are specified.

This function has several calls to increase the buffer indent by 6, then decrease it again, then increase, then decrease. Additionally, there were several printfs that had 6 spaces at the beginning of the line. virDomainActualNetDefFormat, which is called by virDomainNetDefFormat, had similar ugliness. This patch changes both functions to just increase the indent at the beginning, decrease it at (well, just before*) the end, and remove all of the occurences of 6/8 spaces at the beginning of lines. *The indent had to be reset before the end of the function because virDomainDeviceInfoFormat assumes a 0 indent and is called from many other places, and I didn't want to do an overhaul of every caller of that function. A separate patch to switch all of domain_conf.c would be a useful exercise, but my current goal is unrelated to that, so I'll leave it for another day. --- src/conf/domain_conf.c | 73 +++++++++++++++++++++++--------------------------- 1 file changed, 33 insertions(+), 40 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 5990634..8f1f244 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -11560,21 +11560,22 @@ virDomainActualNetDefFormat(virBufferPtr buf, return -1;

Until now, all attributes in a <virtualport> parameter list that were acceptable for a particular type, were also required. There were no optional attributes. One of the aims of supporting <virtualport> in libvirt's virtual networks and portgroups is to allow specifying the group-wide parameters in the network's virtualport, and merge that with the interface's virtualport, which will have the instance-specific info (i.e. the interfaceid or instanceid). Additionally, the guest's interface XML shouldn't need to know what type of network connection will be used prior to runtime - it could be openvswitch, 802.1Qbh, 802.1Qbg, or none of the above - but should still be able to specify instance-specific info just in case it turns out to be applicable. Finally, up to now, the parser for virtualport has always generated a random instanceid/interfaceid when appropriate, making it impossible to leave it blank (which is what's required for virtualports within a network/portprofile definition). This patch modifies the parser and formatter of the <virtualport> element in the following ways: * because most of the attributes in a virNetDevVPortProfile are fixed size binary data with no reserved values, there is no way to embed a "this value wasn't specified" sentinel into the existing data. To solve this problem, the new *_specified fields in the virNetDevVPortProfile object that were added in a previous patch of this series are now set when the corresponding attribute is present during the parse. * allow parsing/formatting a <virtualport> that has no type set. In this case, all fields are settable, but all are also optional. * add a GENERATE_MISSING_DEFAULTS flag to the parser - if this flag is set and an instanceid/interfaceid is expected but not provided, a random one will be generated. This was previously the default behavior, but is now done only for virtualports inside an <interface> definition, not for those in <network> or <portgroup>. * add a REQUIRE_ALL_ATTRIBUTES flag to the parser - if this flag is set the parser will call the new virNetDevVPortProfileCheckComplete() functions at the end of the parser to check for any missing attributes (based on type), and return failure if anything is missing. This used to be default behavior. Now it is only used for the virtualport defined inside an interface's <actual> element (by the time you've figured out the contents of <actual>, you should have all the necessary data to fill in the entire virtualport) * add a REQUIRE_TYPE flag to the parser - if this flag is set, the parser will return an error if the virtualport has no type attribute. This also was previously the default behavior, but isn't needed in the case of the virtualport for a type='network' interface (i.e. the exact type isn't yet known), or the virtualport of a portgroup (i.e. the portgroup just has modifiers for the network's virtualport, which *does* require a type) - in those cases, the check will be done at domain startup, once the final virtualport is assembled (this is handled in the next patch). --- docs/schemas/networkcommon.rng | 114 ++++++-- src/conf/domain_conf.c | 25 +- src/conf/netdev_vport_profile_conf.c | 308 +++++++++++---------- src/conf/netdev_vport_profile_conf.h | 17 +- src/conf/network_conf.c | 7 +- tests/networkxml2xmlin/openvswitch-net.xml | 16 ++ tests/networkxml2xmlin/vepa-net.xml | 6 +- tests/networkxml2xmlout/openvswitch-net.xml | 16 ++ tests/networkxml2xmlout/vepa-net.xml | 6 +- tests/networkxml2xmltest.c | 1 + .../qemuxml2argv-net-virtio-network-portgroup.xml | 14 + 11 files changed, 344 insertions(+), 186 deletions(-) create mode 100644 tests/networkxml2xmlin/openvswitch-net.xml create mode 100644 tests/networkxml2xmlout/openvswitch-net.xml diff --git a/docs/schemas/networkcommon.rng b/docs/schemas/networkcommon.rng index 2328892..f2c3330 100644 --- a/docs/schemas/networkcommon.rng +++ b/docs/schemas/networkcommon.rng @@ -15,22 +15,30 @@ <attribute name="type"> <value>802.1Qbg</value> </attribute> - <element name="parameters"> - <attribute name="managerid"> - <ref name="uint8range"/> - </attribute> - <attribute name="typeid"> - <ref name="uint24range"/> - </attribute> - <attribute name="typeidversion"> - <ref name="uint8range"/> - </attribute> - <optional> - <attribute name="instanceid"> - <ref name="UUID"/> - </attribute> - </optional> - </element> + <optional> + <element name="parameters"> + <optional> + <attribute name="managerid"> + <ref name="uint8range"/> + </attribute> + </optional> + <optional> + <attribute name="typeid"> + <ref name="uint24range"/> + </attribute> + </optional> + <optional> + <attribute name="typeidversion"> + <ref name="uint8range"/> + </attribute> + </optional> + <optional> + <attribute name="instanceid"> + <ref name="UUID"/> + </attribute> + </optional> + </element> + </optional> </element> </group> <group> @@ -38,11 +46,75 @@ <attribute name="type"> <value>802.1Qbh</value> </attribute> - <element name="parameters"> - <attribute name="profileid"> - <ref name="virtualPortProfileID"/> - </attribute> - </element> + <optional> + <element name="parameters"> + <optional> + <attribute name="profileid"> + <ref name="virtualPortProfileID"/> + </attribute> + </optional> + </element> + </optional> + </element> + </group> + <group> + <element name="virtualport"> + <attribute name="type"> + <value>openvswitch</value> + </attribute> + <optional> + <element name="parameters"> + <optional> + <attribute name="profileid"> + <ref name="virtualPortProfileID"/> + </attribute> + </optional> + <optional> + <attribute name="interfaceid"> + <ref name="UUID"/> + </attribute> + </optional> + </element> + </optional> + </element> + </group> + <group> + <!-- use this when no type attribute is present --> + <element name="virtualport"> + <optional> + <element name="parameters"> + <optional> + <attribute name="managerid"> + <ref name="uint8range"/> + </attribute> + </optional> + <optional> + <attribute name="typeid"> + <ref name="uint24range"/> + </attribute> + </optional> + <optional> + <attribute name="typeidversion"> + <ref name="uint8range"/> + </attribute> + </optional> + <optional> + <attribute name="instanceid"> + <ref name="UUID"/> + </attribute> + </optional> + <optional> + <attribute name="profileid"> + <ref name="virtualPortProfileID"/> + </attribute> + </optional> + <optional> + <attribute name="interfaceid"> + <ref name="UUID"/> + </attribute> + </optional> + </element> + </optional> </element> </group> </choice> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 8f1f244..0cda374 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -4404,8 +4404,13 @@ virDomainActualNetDefParseXML(xmlNodePtr node, if (actual->type == VIR_DOMAIN_NET_TYPE_BRIDGE || actual->type == VIR_DOMAIN_NET_TYPE_DIRECT || actual->type == VIR_DOMAIN_NET_TYPE_HOSTDEV) { + /* the virtualport in <actual> should always already + * have an instanceid/interfaceid if its required, + * so don't let the parser generate one */ if (!(actual->virtPortProfile - = virNetDevVPortProfileParse(virtPortNode))) { + = virNetDevVPortProfileParse(virtPortNode, + VIR_VPORT_XML_REQUIRE_ALL_ATTRIBUTES | + VIR_VPORT_XML_REQUIRE_TYPE))) { goto error;

One of the original ideas behind allowing a <virtualport> in an interface definition as well as in the <network> definition *and*one or more <portgroup>s within the network, was that guest-specific parameteres (like instanceid and interfaceid) could be given in the interface's virtualport, and more general things (portid, managerid, etc) could be given in the network and/or portgroup, with all the bits brought together at guest startup time and combined into a single virtualport to be used by the guest. This was somehow overlooked in the implementation, though - it simply picks the "most specific" virtualport, and uses the entire thing, with no attempt to merge in details from the others. This patch uses virNetDevVPortProfileMerge3() to combine the three possible virtualports into one, then uses virNetDevVPortProfileCheck*() to verify that the resulting virtualport type is appropriate for the type of network, and that all the required attributes for that type are present. An example of usage is this: assuming a <network> definitions on host ABC of: <network> <name>testA</name> ... <virtualport type='openvswitch'/> ... <portgroup name='engineering'> <virtualport> <parameters profileid='eng'/> </virtualport> </portgroup> <portgroup name='sales'> <virtualport> <parameters profileid='sales'/> </virtualport> </portgroup> </network> and the same <network> on host DEF of: <network> <name>testA</name> ... <virtualport type='802.1Qbg'> <parameters typeid="1193047" typeidversion="2"/> </virtualport> ... <portgroup name='engineering'> <virtualport> <parameters managerid="11"/> </virtualport> </portgroup> <portgroup name='sales'> <virtualport> <parameters managerid="55"/> </virtualport> </portgroup> </network> and a guest <interface> definition of: <interface type='network'> <source network='testA' portgroup='sales'/> <virtualport> <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f" interfaceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f"\> </virtualport> ... </interface> If the guest was started on host ABC, the <virtualport> used would be: <virtualport type='openvswitch'> <parameters interfaceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f' profileid='sales'/> </virtualport> but if that guest was started on host DEF, the <virtualport> would be: <virtualport type='802.1Qbg'> <parameters instanceid="09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f" typeid="1193047" typeidversion="2" managerid="55"/> </virtualport> Additionally, if none of the involved <virtualport>s had a specified type (this includes cases where no virtualport is given at all), --- docs/formatdomain.html.in | 72 ++++++++++++++++++++++++++++++++++++------- docs/formatnetwork.html.in | 27 ++++++++++++----- src/network/bridge_driver.c | 74 ++++++++++++++++++++++++++++++++------------- 3 files changed, 134 insertions(+), 39 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index f97c630..f3b3fa8 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -2230,11 +2230,40 @@ the network; one network may have multiple portgroups defined, with each portgroup containing slightly different configuration information for different classes of network - connections. <span class="since">Since 0.9.4</span>).
