MeowOS
52edf0c9e4
NETMGR_DESIGN.md 期2范围落地（全在 patch_v2/meow_netmgrd/ + meow_ipc.h 追加）：
- 连接普查(§4)：每 2s 解析 /proc/net/{tcp,udp}(IPv4) → socket inode→pid（由 inode 集驱动扫
/proc/<pid>/fd，不逐 pid 盲扫）→ 三实体归因 app:<pkg>(amsd status)/svc:<svc>(svcd 落盘状态
/tmp/meow_svcd.status，socket 查询兜底)/proc:<comm>(无则 proc:unknown)。连接表静态 ≤512：
entity/五元组/状态/寿命；远端 IP 由 DNS 缓存反查域名。
- DNS 代理(§5)：监听 127.0.0.1:53 UDP；启动备份 resolv.conf 写双行(127.0.0.1+原上游，崩溃零断流)；
透传转发+缓存(TTL 尊重；≤256 条)；按源端口(port→entity)归因；域名规则 per-entity+global allow/deny
(deny→NXDOMAIN+日志)；atexit/SIGTERM/SIGHUP 恢复；5s 自检被第三方改回即重写；HibyOS 绝不启用/绝不改 resolv。
DNS wire(deny NXDOMAIN / forward→A+cache / NXDOMAIN id 回显) 宿主+qemu 实测 PASS。
- 事件日志(§8)：新连接/关闭/dns deny/接口状态变化；同 entity 同 dst 1 分钟去重(首条+计数)。
- IPC meow_ipc.h 追加 0x00E8 CONNS_REQ/RESULT、0x00EC DNS_CTL/RESULT（纯追加不改既有行；
0x00EA 策略(期3)/0x00EE 事件推送(预留) 保留）。
- CLI meow_net 补 apps / conns [entity] / top(2s 刷新) / dns status|stats|flush。
- 内存：静态表禁 malloc，mipsel bss 228KB → RSS≈374KB，≤600KB 目标 / ≤1MB 预算。
宿主编译 -Wall -Wextra 0 warning；test_netmgrd.sh 48/48(宿主+qemu)、test_netmgrd_p2 全过(宿主+qemu)、
netmgrd_authtest 全过；真机(M6.0/0.8.0)只读实测 apps/conns/dns status 正确
（svc:meowpanel/svc:mdnsd/proc:dropbear 真实三实体归因），resolv.conf 测后核验原值未触碰。
