Graham McIntire	6bf9584cb2	test: push coverage from 92% to 97.6% (249 tests) ... Refactor main.go to extract testable runMain() function, make icmpListenPacket and syscallExec injectable, fix worker pool tests to properly fill queue buffers (n*4 capacity). Add comprehensive tests for CLI argument parsing, ping exec fallback, ICMP timeout paths, self-update happy path, and SNMP context cancellation.	2026-03-04 16:35:02 -06:00
Graham McIntire	f35be66148	fix ICMP ping in Docker by trying raw sockets before unprivileged UDP ... The old code only tried unprivileged UDP ICMP (udp4), which relies on the ping_group_range sysctl — not CAP_NET_RAW. Docker doesn't set that sysctl, so pings always timed out and fell through to exec. Now tries raw ICMP sockets (ip4:icmp) first, which properly uses CAP_NET_RAW. Also sets cap_net_raw+ep on the agent binary in the Dockerfile.	2026-02-12 11:18:21 -06:00
