Only parse PROXY protocol headers from connections originating from configured trusted source IPs. Connections from untrusted sources have their PROXY headers ignored and use the actual socket IP. This follows the HAProxy proxy protocol specification recommendation to verify that proxy protocol traffic comes from trusted sources. Configuration: [amqp] tcp_proxy_protocol = 1 proxy_protocol_trusted_sources = 10.0.0.1, 10.0.0.2 Co-Authored-By: Claude Opus 4.5 <[email protected]>

Extends proxy_protocol_trusted_sources config to support CIDR notation (e.g., 192.168.0.0/24, 2001:db8::/32) alongside exact IP addresses. Creates IPMatcher struct optimized for the common case of exact IP matching while supporting flexible network range specifications. Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
