Fabric Module#

The Fabric module provides network control and Linux network fabric management capabilities, allowing applications to interact with and manage the Linux network stack.

🔌 Interface Management#

Interface#

Network interface representation and information:

Features:

Interface enumeration and queries
IP address assignment information
MTU (Maximum Transmission Unit) queries
Interface flags and status
Link-layer address information

Operations:

Query interface properties
Get assigned IP addresses
Check interface state (up/down)
Access hardware (MAC) addresses

Interface Manager#

System-wide network interface management using Netlink:

Features:

Interface discovery and enumeration
Real-time interface monitoring
Address family filtering (IPv4/IPv6)
Interface status tracking
Event-based notifications

Operations:

List all network interfaces
Monitor interface changes
Filter by address family
Query interface capabilities

Implementation:

Built on Linux Netlink sockets

Event-driven updates

🔍 ARP (Address Resolution Protocol)#

ARP protocol implementation for mapping IP addresses to MAC addresses:

Features:

ARP request/reply handling
MAC address resolution from IP
Network layer utilities
Broadcast and unicast ARP

Operations:

Send ARP requests
Parse ARP replies

Service name resolution
IPv4 and IPv6 support
Forward and reverse lookups
Multiple address results

Operations:

Resolve hostnames to IP addresses
Resolve service names to port numbers
Reverse DNS lookups (IP to hostname)
Query multiple addresses per hostname

Protocol Support:

IPv4 (A records)
IPv6 (AAAA records)
PTR records (reverse lookup)
Service/protocol resolution
