fix: add hardening compiler flags in debian/rules

[mhduiy]

1. Added DEB_CFLAGS_MAINT_APPEND with -Wall for C compiler warnings
2. Added DEB_CXXFLAGS_MAINT_APPEND with -Wall for C++ compiler warnings
3. Added DEB_LDFLAGS_MAINT_APPEND with multiple security hardening flags:
   • --as-needed for linker optimization
   • -z relro for RELRO protection
   • -z now for immediate binding
   • -z noexecstack for non-executable stacks
   • -E for exporting symbols
4. These changes improve security and code quality by enabling additional warnings and linker protections

fix: 在 debian/rules 中添加编译器加固标志

1. 为 C 编译器添加 DEB_CFLAGS_MAINT_APPEND 并启用 -Wall 警告
2. 为 C++ 编译器添加 DEB_CXXFLAGS_MAINT_APPEND 并启用 -Wall 警告
3. 为链接器添加 DEB_LDFLAGS_MAINT_APPEND 包含多个安全加固标志：
   • --as-needed 用于链接器优化
   • -z relro 用于 RELRO 保护
   • -z now 用于立即绑定
   • -z noexecstack 用于非可执行栈
   • -E 用于导出符号
4. 这些更改通过启用额外的警告和链接器保护来提高安全性和代码质量

Summary by Sourcery

在提供的 debian/rules 文件更改中，添加了一些新的环境变量来增强构建过程中的编译和链接选项。以下是对这些更改的审查：

代码质量

• 环境变量设置：新增的环境变量 DEB_CFLAGS_MAINT_APPEND、DEB_CXXFLAGS_MAINT_APPEND 和 DEB_LDFLAGS_MAINT_APPEND 用于追加编译器和链接器的标志。这些标志有助于提高代码质量，例如启用所有警告 (-Wall)，以及优化链接过程 (-Wl,--as-needed, -Wl,-z,relro, -Wl,-z,now, -Wl,-z,noexecstack, -Wl,-E)。

代码性能

• 链接优化：添加的链接器标志 -Wl,--as-needed、-Wl,-z,relro、-Wl,-z,now、-Wl,-z,noexecstack 和 -Wl,-E 旨在优化二进制文件的性能和安全性。例如，-Wl,--as-needed 会移除未使用的库，-Wl,-z,relro 和 -Wl,-z,now 用于减少内存泄漏，-Wl,-z,noexecstack 防止栈溢出攻击，-Wl,-E 确保所有符号都可见。

代码安全性

• 编译器警告：通过 -Wall 标志启用所有编译器警告，有助于发现潜在的错误和问题，从而提高代码的安全性。
• 链接器安全选项：-Wl,-z,relro 和 -Wl,-z,now 选项有助于提高二进制文件的安全性，通过减少内存泄漏和延迟绑定。

代码维护

• 环境变量命名：使用 DEB_ 前缀来命名环境变量，符合 Debian 包维护的最佳实践，确保这些设置在构建过程中被正确应用。

建议

• 文档说明：建议在 debian/rules 文件中添加注释，说明为什么选择这些特定的编译和链接标志，以及它们对项目的影响。这有助于其他维护者理解这些更改的目的和重要性。

总体来说，这些更改有助于提高代码的质量、性能和安全性，是一个积极的改进。
