public (active) target: default icmp-block-inversion: no interfaces: eth0 sources: services: dhcpv6-client ssh ports: 1080/udp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:

这个输出表明，您已经成功地将 UDP 端口 1080 添加到了公共区域的防火墙规则中。具体来说，输出中的各个部分含义如下：

- `public (active)`：表示当前活动的区域是公共区域。
- `target: default`：表示默认的防火墙策略是允许所有流量通过。
- `icmp-block-inversion: no`：表示未禁止 ICMP 阻塞反转（即允许 ICMP 流量通过）。
- `interfaces: eth0`：表示仅允许通过网络接口 eth0 的流量通过。
- `sources:`：表示未限制传入流量的来源。
- `services: dhcpv6-client ssh`：表示允许 DHCPv6-客户端和 SSH 服务的流量通过。
- `ports: 1080/udp`：表示允许 UDP 协议的 1080 端口的流量通过。
- `protocols:`：表示未限制通过防火墙的协议。
- `masquerade: no`：表示未启用伪装（即源地址转换）。
- `forward-ports:`：表示未设置端口转发规则。
- `source-ports:`：表示未限制传出流量的源端口。
- `icmp-blocks:`：表示未禁止任何 ICMP 类型的流量。
- `rich rules:`：表示未定义任何复杂的防火墙规则。

请注意，这只是当前防火墙规则的一个摘要，实际上可能包含更多的规则和细节。如果您需要更详细的信息，请尝试运行 `firewall-cmd --list-all` 命令。

Provide a minimal set of RISC-V instructions that may be used to implement the following pseudoinstruction: not x5, x6 // bit-wise invert

The RISC-V ISA does not have a NOT instruction for bit-wise inversion of a register. However, we can still implement this operation using a combination of other RISC-V instructions. One possible set of instructions that can be used to implement the bit-wise inversion operation for registers x5 and x6 are:

    xori x5, x6, -1

Explanation:

The `xori` instruction performs a bit-wise Exclusive-OR operation between the source register `x6` and the immediate value `-1`, which is represented in binary as all 1's. This has the effect of inverting all the bits in `x6` and storing the result in `x5`. Therefore, the above instruction is equivalent to the pseudoinstruction `not x5, x6` in terms of bit-wise inversion.

Note that the above instruction assumes that the initial value of register `x6` is zero-extended to 32 bits. If `x6` contains a value that is sign-extended to 32 bits, we need to use a different immediate value for the `xori` instruction. For example, if `x6` contains the value -1 (represented in binary as all 1's), we can use the immediate value 0 instead of -1, like this:

    xori x5, x6, 0

This will perform the same bit-wise inversion operation as before, but with the correct immediate value for sign-extended register values.
