zhanghongyu 2b0a4a20f5 iptables: add file lock to prevent concurrent overwrite ... the kernel can only prevent the concurrency of s/getsockopt, but iptables will call these interfaces multiple times at a time. We need to wait for one iptables to complete before executing the second one, otherwise the data will be overwritten. iptables flow: get current iptables entries [1] -> add new entry 2 [1,2] -> set to kernel [1,2] get current iptables entries [1] -> add new entry 3 [1,3] -> set to kernel [1,3] entry 2 is lost Signed-off-by: zhanghongyu <zhanghongyu@xiaomi.com>		2026-01-15 17:20:03 +08:00
