[PATCH V7 7/7] vlan extention - CIM Model - VESSMS
by Wenchao Xia 14 Feb '12

14 Feb '12

This patch added a new service class VESSMS which can modify host network about adding, modifying, deleting 802.1.q vlan and bridge. The model of bridge modification is according to VSMS model, and on DSP1097 it says virtual switch should be managed similar to ComputerSystem. The model of allocation of vlan port, is on chapter 9.1.2 of DSP1050_1.0. Difference is that, this patch did not use Parent propety to identify which switch it should belongs to, but use property InstanceID to say it, such as VS_eth0/EA_eth0.10, because using Parent for port allocation needs to implement EC_POOL making things more complicate. The model of connecting of vlan port with bridge, is on chapter 9.1.4 of DSP1050_1.0. The patch matches it despite of that EA_POOL and EC_POOL are not implemented. V7: Some host network checking such as checking of existence for an EthIface before modify it, are moved to function library. Code style changed to fit libvirt-cim. Added properties AutoStart, DHCP, Delay. Other things are same with V2.

[PATCH V7 6/7] vlan extention - CIM Model - EASD
by Wenchao Xia 14 Feb '12

14 Feb '12

Add EASD for EthernetPort. According DSP1050, There are two kinds of EASD: EA stands for Settings of EthernetPort, EC stands for Settings for Connection between EthernetPort. EA_POOL and EC_POOL are not implemented, the model standard is described with more details in next patch. V7: add CIM properties AutoStart, DHCP. V6: almost the same with V2.

[PATCH V7 5/7] vlan extention - CIM Model - EthernetPort
by Wenchao Xia 14 Feb '12

14 Feb '12

This patch add EthernetPort. EthernetPort is always a port on a switch, So eth0.10 is modeled as VS_eth0/EP_eth0.10, and eth0 is modeled as VS_eth0/EP_Eth0. To make things simple enough, EtherPort belongs to VMs, are excluded from the patch and still be modeled as NetworkPort. This means the patch only concern about network on host side. V7: no change. V6: minior change according to comments. V5: almost the same with V2.

[PATCH V7 3/7] vlan extention - CIM Model - VESS
by Wenchao Xia 14 Feb '12

14 Feb '12

This patch add VESS according DSP1097. VESS is modeled similar to ComputerSystem. V7: added state change code which bring up or down ethiface. V6: little change about style. V5: Almost no change from V2, just removed one parameter when calling function library.

[PATCH V7 1/7] vlan extention - function libarary
by Wenchao Xia 14 Feb '12

14 Feb '12

This patch add function libarary and test program with libvirt API. Limit: It have only DHCP property about IP settings. Other settings such IP and mask are ignored, in most cases ip are got by DHCP. V7: Add codes of writing about network configuration. Codes such as iface comparing and duplication are removed comparing to V2, which brings some limit to the usage of API and structure, but make things more simple. V6: Code changes according to comments. V5: Calling libvirt API instead of implement my own.

[PATCH V7 0/7] vlan 802.1.q extention
by Wenchao Xia 14 Feb '12

14 Feb '12

These patches add vlan extention of host network. Many code are used to build up the network model, which is very similar to ComputerSystem. Patch 1 contains function library codes and C test program. From Patch 2 to 6, it is almost readonly codes, except VESS state change. Patch 7 are CIM model codes of writing network configuration. Limit: Now only DHCP on/off are supported about IP settings, mannually setting of address and netmask are not considered. v7: added portion of code about writing. v6: added CIM model for readonly usage. Code changes according to comments. v5: switched to libvirt API about to enable readonly library. v4: using netlink 1.0 as implemention to avoid runtime errors. v3: using netlink 3.0 and libbridge as implemention. v2: code fix and bug fix. v1: using string parsing and direct accessing with host configuration file, which require some utilities installed, such as IP, VCONFIG. git repository: git://gitorious.org/libvirt-cim_develop/libvirt-cim_develop.git branch vlan_v7 Wenchao Xia (7): vlan extention - function libarary vlan extention - CIM Model - helper and Makefile vlan extention - CIM Model - VESS vlan extention - CIM Model - VESSSD vlan extention - CIM Model - EthernetPort vlan extention - CIM Model - EASD vlan extention - CIM Model - VESSMS Makefile.am | 16 +- libxkutil/Makefile.am | 14 +- libxkutil/misc_util.c | 48 + libxkutil/misc_util.h | 3 + libxkutil/network_model_helper.c | 473 +++++++ libxkutil/network_model_helper.h | 101 ++ libxkutil/network_parsing.c | 1309 ++++++++++++++++++++ libxkutil/network_parsing.h | 217 ++++ libxkutil/network_parsing_test.c | 184 +++ libxkutil/xmlgen.c | 4 +- libxkutil/xmlgen.h | 4 + schema/EthernetPort.mof | 4 + schema/EthernetPort.registration | 3 + schema/EthernetPortAllocationSettingData.mof | 22 + .../EthernetPortAllocationSettingData.registration | 3 + schema/VirtualEthernetSwitchSystem.mof | 10 + schema/VirtualEthernetSwitchSystem.registration | 3 + ...irtualEthernetSwitchSystemManagementService.mof | 14 + ...ernetSwitchSystemManagementService.registration | 3 + schema/VirtualEthernetSwitchSystemSettingData.mof | 33 + ...ualEthernetSwitchSystemSettingData.registration | 3 + src/Makefile.am | 29 +- src/Virt_EASD.c | 711 +++++++++++ src/Virt_EASD.h | 59 + src/Virt_EthernetPort.c | 561 +++++++++ src/Virt_EthernetPort.h | 58 + src/Virt_HostSystem.c | 2 +- src/Virt_HostSystem.h | 2 + src/Virt_VESSSD.c | 392 ++++++ src/Virt_VESSSD.h | 39 + src/Virt_VirtualEthernetSwitchSystem.c | 477 +++++++ src/Virt_VirtualEthernetSwitchSystem.h | 52 + ..._VirtualEthernetSwitchSystemManagementService.c | 1289 +++++++++++++++++++ ..._VirtualEthernetSwitchSystemManagementService.h | 31 + src/Virt_VirtualSystemManagementService.c | 2 +- src/Virt_VirtualSystemManagementService.h | 4 + 36 files changed, 6167 insertions(+), 12 deletions(-) create mode 100644 libxkutil/network_model_helper.c create mode 100644 libxkutil/network_model_helper.h create mode 100644 libxkutil/network_parsing.c create mode 100644 libxkutil/network_parsing.h create mode 100644 libxkutil/network_parsing_test.c create mode 100644 schema/EthernetPort.mof create mode 100644 schema/EthernetPort.registration create mode 100644 schema/EthernetPortAllocationSettingData.mof create mode 100644 schema/EthernetPortAllocationSettingData.registration create mode 100644 schema/VirtualEthernetSwitchSystem.mof create mode 100644 schema/VirtualEthernetSwitchSystem.registration create mode 100644 schema/VirtualEthernetSwitchSystemManagementService.mof create mode 100644 schema/VirtualEthernetSwitchSystemManagementService.registration create mode 100644 schema/VirtualEthernetSwitchSystemSettingData.mof create mode 100644 schema/VirtualEthernetSwitchSystemSettingData.registration create mode 100644 src/Virt_EASD.c create mode 100644 src/Virt_EASD.h create mode 100644 src/Virt_EthernetPort.c create mode 100644 src/Virt_EthernetPort.h create mode 100644 src/Virt_VESSSD.c create mode 100644 src/Virt_VESSSD.h create mode 100644 src/Virt_VirtualEthernetSwitchSystem.c create mode 100644 src/Virt_VirtualEthernetSwitchSystem.h create mode 100644 src/Virt_VirtualEthernetSwitchSystemManagementService.c create mode 100644 src/Virt_VirtualEthernetSwitchSystemManagementService.h

[PATCH v6 0/3] Implementation of a linked list helper
by Eduardo Lima (Etrunko) 03 Feb '12

03 Feb '12

From: "Eduardo Lima (Etrunko)" <eblima(a)br.ibm.com> This series provides a generic linked list implementation for libxkutil that is based on the one originally developed for the libvirt domain events support recently integrated upstream. As test case I ported the ComputerSystemIndication provider code to use this list implementation. In the near future it will be also used by the event loop that I am currently working on to allow systems with libvirt older than 0.9.0 to make use of the same feature. Other possible use cases would be to port the code of libxkutil/*_parsing* to also use the list implementation instead of static arrays. Changes from v5: - Fix possible NULL dereference in list_first() Changes from v4: - Fix possible NULL dereference in list_last_node() - Fix possible leak in acl_parsing.c Changes from v3: - Fix crashes in list_free(), list_first_node() and list_count() - Include patch that ports the acl filter ref code to use the linked list implementation Changes from v2: - Make list struct private Changes from v1: - Fix version iformation in Makefile.am Eduardo Lima (Etrunko) (3): libxkutil: Linked list helper CSI: Use list helper implementation ACL: Use linked list helper for filter refs libxkutil/Makefile.am | 51 +++++-- libxkutil/acl_parsing.c | 58 +++------ libxkutil/acl_parsing.h | 5 +- libxkutil/list_util.c | 254 +++++++++++++++++++++++++++++++++++ libxkutil/list_util.h | 73 ++++++++++ libxkutil/xmlgen.c | 30 +++- src/Virt_ComputerSystemIndication.c | 95 ++++---------- src/Virt_NestedFilterList.c | 73 ++++++----- 8 files changed, 472 insertions(+), 167 deletions(-) create mode 100644 libxkutil/list_util.c create mode 100644 libxkutil/list_util.h -- 1.7.7.6
