[libvirt] [PATCH v2 0/6] lxc: Add suport to network indexes for LXC 3.X.
This series implement support for network syntax settings for LXC 3.X. Now, indexes are part of the settings to define network interfaces. Each interface has its own index. The old style uses 'type' tag to differentiate each interface. Old: lxc.network.type = veth lxc.network.flags = up lxc.network.link = virbr0 New: lxc.net.0.type = veth lxc.net.0.flags = up lxc.net.0.link = virbr0 v1-v2: Error condition was causing segfault due to wrong index access. Julio Faracco (6): lxc: Rebase lxcNetworkParseData struct to support indexes. lxc: Rebase lxcNetworkParseData pointers to use new structures. lxc: Introduce lxcNetworkGetParseDataLegacy() method. lxc: Introduce lxcNetworkGetParseData() for 'lxc.net.' entry. tests: Change network settings of V3 testcase set. tests: Introduce random network settings to test indexes. src/lxc/lxc_native.c | 192 ++++++++++++------ .../lxcconf2xml-ethernet-v3.config | 16 +- .../lxcconf2xml-fstab-v3.config | 10 +- .../lxcconf2xml-macvlannetwork-v3.config | 10 +- .../lxcconf2xml-miscnetwork-v3.config | 38 ++-- .../lxcconf2xml-nonenetwork-v3.config | 2 +- .../lxcconf2xml-physnetwork-v3.config | 14 +- .../lxcconf2xml-randomnetwork-v3.config | 21 ++ .../lxcconf2xml-randomnetwork.xml | 45 ++++ .../lxcconf2xml-simple-v3.config | 18 +- .../lxcconf2xmldata/lxcconf2xml-simple.config | 18 +- .../lxcconf2xml-vlannetwork-v3.config | 10 +- tests/lxcconf2xmltest.c | 1 + 13 files changed, 268 insertions(+), 127 deletions(-) create mode 100644 tests/lxcconf2xmldata/lxcconf2xml-randomnetwork-v3.config create mode 100644 tests/lxcconf2xmldata/lxcconf2xml-randomnetwork.xml -- 2.19.1
The current logic of lxcNetworkParseData uses one single structure to record data over the network definitions inside config files. The logic consider the entry 'type' as a new network definition, every time that algorithm find this tag. This new structure was designed to consider network definitions as an array of network structures.

I do think there is value in just adding the *Ptr value and then using within the code rather than "lxcNetworkParseData *data". That is introduce the lxcNetworkParseDataPtr in the same patch as you change anything that uses "lxcNetworkParseData *data" to use "lxcNetworkParseDataPtr data" instead.

The following should be separated into its own patch with the similar format as above using: typedef struct _lxcNetworkParseArray lxcNetworkParseArray; typedef lxcNetworkParseArray *lxcNetworkParseArrayPtr; struct _lxcNetworkParseArray {

This should be "networks" not "data" for the normal naming scheme used. It is also arguably separable since it's new and introducing a new concept. John

As the compiler tells you @networks is not used
+ lxcNetworkParseDataPtr parseData = NULL;
If you took this one patch at a time, then @data "used" to be a pointer to a structure of mostly empty data with a filled in @def and this changes it to a NULL structure, which doesn't feel quite right. That means lxcNetworkParseDataEntry gets called w/ NULL parameter in 3rd parameter. Going to stop here and wait for the next series... I think removing the @networks and @privnet from _lxcNetworkParseData should be one step and then the removal of @def another step. John
