ADD-SP/ngx_waf v6.0.0-beta.4

on GitHub

[6.0.0-beta.4] - 2021-07-16 UTC+0800

NOTE

• This release contains some breaking changes.

• Advanced rules have a high performance cost because the principle is to compile the rules into a series of instructions that are then executed by the VM.

Upgrade from 5.x.x to 6.x.x

1. Create a new empty file named advanced in the rules directory.

2. If the directive waf_priority is used, you can delete it or modify it according to the directive in the documentation.

Pre-built modules

We now provide pre-compiled modules that can be used as long as the following requirements are met.

1. The version of nginx must be the latest stable or mainline version.
2. The C standard library implementation must be the GNU implementation or the MUSL implementation.

The download script will automatically check if the second condition is met.

You can execute assets/download.sh to download the corresponding version of the module and save it to the current directory. Here is the use case.

# nginx-stable ngx_waf-stable
sh assets/download stable stable

# nginx-mainline ngx_waf-stable
sh assets/download mainline stable

# nginx-stable ngx_waf-beta
sh assets/download stable beta

# nginx-mainline ngx_waf-beta
sh assets/download mainline beta

Each update takes about an hour and a half to compile the module, so it is recommended that you download the updated module more than two hours after the update, otherwise you may download the old module.

Added

• Advanced rules are supported, see the documentation for details.

Removed

• Remove mode COMPAT, no longer fully compatible with ngx_http_rewrite_module.

Changed

• Updated the directive waf_priority, see the documentation for details.

• You can now use all the directives of this module in blocks http, server and location

[6.0.0-beta.4] - 2021-07-16 UTC+0800

注意

• 本次更新有一些不向下兼容的改动。

• 高级规则的执行速度较慢，因为其原理是将规则编译成一系列指令，然后由虚拟机执行。

预构建模块

现在我们提供了提前编译好的模块，只要满足了下列要求即可使用。

1. nginx 的版本必须是最新的 stable 或 mainline 版本。
2. 您使用的 C 语言的标准库实现必须是 GNU 实现或者 musl 实现。

下载脚本会自动检查是否满足第二个条件。

您可以执行 assets/download.sh 来下载对应版本的模块并保存到当前目录。下面是用例。

# nginx-stable ngx_waf-stable
sh assets/download stable stable

# nginx-mainline ngx_waf-stable
sh assets/download mainline stable

# nginx-stable ngx_waf-beta
sh assets/download stable beta

# nginx-mainline ngx_waf-beta
sh assets/download mainline beta

每次更新都需要花费约一个半小时的时间来编译模块，所以推荐在更新超过两个小时后再下载更新后的模块，否则可能会下载到旧的模块。

从 5.x.x 升级到 6.x.x

1. 在规则目录下新建一个名为 advanced 的空文件。
2. 如果使用了配置项 waf_priority，可以将其删除或者按照文档中对该配置项的说明进行修改。

新增

• 支持了高级规则，详情见文档。

移除

• 移除 COMPAT 模式，不再完全兼容 ngx_http_rewrite_module。

变动

• 更新了配置项 waf_priority，详情见文档。

• 现在你可以在 http、server 和 location 块中使用本模块的所有配置项。
