Key-Value Store The Key-Value (KV) Store is used for the following state: Policy Identities: list of labels <=> policy identity identifier to configure ENI IPAM specific parameters. Failure Behavior If Cilium loses connectivity with the KV-Store, it guarantees that: Normal networking operations will continue; If policy enforcement is enabled connectivity is restored to the KV-Store, Cilium can take up to 5 minutes to re-sync the out-of-sync state with the KV-Store. Cilium will keep running even if it is out-of-sync with the KV-Store. If Cilium crashes

If the command does not describe the status of the other node, there may be an issue with the KV-Store. 2. Run cilium monitor on the node of the source and destination endpoint. Look for packet about the key and value structures. For example, BTF in combination with BPF maps and the BPF_ANNOTATE_KV_PAIR() macro from iproute2 will result in the following dump (test_xdp_noinline.o from kernel selftests):

eBPF 技术 在 Linux kernel 3.19 开始被 引入，可在用户态进行 eBPF 程序编程，编译 后，动态加载到内核指定的 hook 点上，以 VM 方式安全运行，其能过通过 map 存储结 构存储数据，能通过 map 同用户态程序交互， 最终实现内核数据进行修改，或者影响内核处 理请求的结果，或者改变内核处理请求的流程。 极大提升了内核处理事件的效率。 截止 linux 5.14 版本，eBPF
