Re: [libvirt] [PATCH v7 1/4] net-dhcp-leases: Implement the public APIs

Introduce 3 new APIs, virNetworkGetDHCPLeases, virNetworkGetDHCPLeasesForMAC and virNetworkDHCPLeaseFree. * virNetworkGetDHCPLeases: returns the dhcp leases information for a given virtual network. For DHCPv4, the information returned: - Network Interface Name - Expiry Time - MAC address - IAID (NULL) - IPv4 address (with type and prefix) - Hostname (can be NULL) - Client ID (can be NULL) For DHCPv6, the information returned: - Network Interface Name - Expiry Time - MAC address - IAID (can be NULL, only in rare cases) - IPv6 address (with type and prefix) - Hostname (can be NULL) - Client DUID Note: @mac, @iaid, @ipaddr, @clientid are in ASCII form, not raw bytes. Note: @expirytime can 0, in case the lease is for infinite time. * virNetworkGetDHCPLeasesForMAC: returns the dhcp leases information for a given virtual network and specified MAC Address. * virNetworkDHCPLeaseFree: allows the upper layer application to free the network interface object conveniently. There is no support for flags, so user is expected to pass 0 for both the APIs. include/libvirt/libvirt.h.in: * Define virNetworkGetDHCPLeases * Define virNetworkGetDHCPLeasesForMAC * Define virNetworkDHCPLeaseFree src/driver.h: * Define networkGetDHCPLeases * Define networkGetDHCPLeasesForMAC src/libvirt.c: * Implement virNetworkGetDHCPLeases * Implement virNetworkGetDHCPLeasesForMAC * Implement virNetworkDHCPLeaseFree src/libvirt_public.syms: * Export the new symbols --- include/libvirt/libvirt.h.in | 34 ++++++++ src/driver.h | 13 ++++ src/libvirt.c | 179 +++++++++++++++++++++++++++++++++++++++++++ src/libvirt_public.syms | 3 + 4 files changed, 229 insertions(+) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index c83b20d..b3120e2 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -5162,6 +5162,40 @@ typedef enum { #endif } virNetworkEventID; +typedef enum { + VIR_IP_ADDR_TYPE_IPV4, + VIR_IP_ADDR_TYPE_IPV6, + +#ifdef VIR_ENUM_SENTINELS + VIR_IP_ADDR_TYPE_LAST +#endif +} virIPAddrType; + +typedef struct _virNetworkDHCPLease virNetworkDHCPLease; +typedef virNetworkDHCPLease *virNetworkDHCPLeasePtr; +struct _virNetworkDHCPLease { + char *interface; /* Network interface name */
