[英]libseccomp patch for hash maps

Has this patch been merged or rejected? 此补丁是否已合并或拒绝？ Or the discussion has just ended without evolving? 还是讨论没有发展就结束了？ Maybe the fact that seccomp filters can be rewritten as binary trees is enough to don't add hash maps support for seccomp? 也许seccomp过滤器可以重写为二叉树的事实足以不添加对seccomp的哈希映射支持？

Yes, I struggle to follow kernel patches discussions and to understand if they are merged or not XD :( 是的，我努力跟踪内核补丁讨论，并了解它们是否已合并XD :(

1 个解决方案

That patch has not been merged. 该补丁尚未合并。 seccomp-bpf still doesn't support eBPF bytecode or even just maps. seccomp-bpf仍然不支持eBPF字节码，甚至不支持映射。 It seems unlikely that seccomp-bpf will ever rely on eBPF instead of cBPF. seccomp-bpf 似乎不太可能会依赖eBPF而不是cBPF。

Binary trees were indeed considered a good enough solution for anyone who needs very high seccomp-bpf performance. 对于需要非常高seccomp-bpf性能的任何人，二进制树确实被认为是一个足够好的解决方案。 Although I don't think libseccomp supports binary trees yet . 虽然我不认为libseccomp还支持二进制树。
