Re: [libvirt] [PATCH v2] Add helper program to create custom leases

Introduce helper program to catch events from dnsmasq and maintain a custom lease file per network. It supports dhcpv4 and dhcpv6. The file is saved as "<interface-name>.status". Each lease contains the following info: <expiry-time (epoch time)> <mac> <iaid> <ip-address> <hostname> <clientid> Example of custom leases file content: [ { "expiry-time": "1390775837", "mac-address": "52:54:00:93:8c:63", "iaid": "*", "ip-address": "192.168.150.209", "hostname": "iit-ad885e4aa1", "client-id": "01:52:54:00:44:7c:d7" }, { "expiry-time": "1390775950", "mac-address": "52:54:00:7b:6f:ba", "iaid": "8089530", "ip-address": "2001:db8:ca2:2:1::6d", "hostname": "*", "client-id": "00:04:76:00:cf:ae:b3:0b:fc:cd:0e:22:2e:97:76:65:74:ec" } ] src/Makefile.am: * Add options to compile the helper program src/network/bridge_driver.c: * Introduce networkDnsmasqLeaseFileNameCustom() * Invoke helper program along with dnsmasq * Delete the .status file when corresponding n/w is destroyed. src/util/leaseshelper.c * Helper program to create the custom lease file --- v2: * Changed format to JSON v1: * Refer: https://www.redhat.com/archives/libvir-list/2014-January/msg00626.html src/Makefile.am | 20 ++++ src/network/bridge_driver.c | 19 ++++ src/util/leaseshelper.c | 271 ++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 310 insertions(+) create mode 100644 src/util/leaseshelper.c
