OpenWrt 21.02 Arrives With Linux Kernel 5.4 & WPA3 Support
|
||||
======
|
||||
|
||||
The OpenWrt community announced the first stable update of their series, OpenWrt 21.02.
|
||||
|
||||
In case you did not know, OpenWrt is a project that helps create custom operating systems for embedded devices.
|
||||
|
||||
It enables users to openly customize their devices according to their networking needs, something that the stock router firmware doesn’t. Other than routers, OpenWrt can run on a variety of devices such as smartphones, residential gateways, and even 32 bit PCs!
|
||||
|
||||
With this release, they have over 5800 commits since the older OpenWrt 19.07.
|
||||
|
||||
Let us take a look at what is new with OpenWrt 21.02.
|
||||
|
||||
### OpenWrt 21.02: What’s New?
|
||||
|
||||
While there are several technical changes and improvements, let me highlight the key additions.
|
||||
|
||||
#### WPA3 Support
|
||||
|
||||
Although present in the 19.07 release, the latest security standard for Wi-Fi networks is now included by default in the images.
|
||||
|
||||
WPA3 stands for Wi-Fi Protected Access 3 and is a major improvement in terms of security over the popular WPA2. Backward compatibility is also supported.
|
||||
|
||||
#### TLS and HTTPS Support
|
||||
|
||||
Just like WPA3, TLS and HTTPS support is also included by default. This comes with the trusted CA certificates from Mozilla as well.
|
||||
|
||||
With this addition, _wget_ and _opkg_ should now support fetching resources over HTTPS out-of-the-box. Moreover, [LuCl][1] is available over HTTPS in addition to HTTP.
|
||||
|
||||
#### Initial DSA Support
|
||||
|
||||
As the release announcement states:
|
||||
|
||||
“DSA stands for Distributed Switch Architecture and is the Linux standard to deal with configurable Ethernet switches”
|
||||
|
||||
This has replaced the _swconfig_ system which was being used until now. This is a notable change to how VLANs and switch ports are managed.
|
||||
|
||||
#### New Minimum Hardware Requirements
|
||||
|
||||
With numerous new features and updates to OpenWrt, including the increase in the general size of the Linux kernel, the minimum requirements have been increased.
|
||||
|
||||
Devices now require at least 8 MB of flash and 64 MB memory to run the default build ensuring proper stability.
|
||||
|
||||
#### Package Updates
|
||||
|
||||
The release also comes packed in with several package upgrades, some of them are:
|
||||
|
||||
* Linux kernel 5.4.143
|
||||
* gcc 8.4.0
|
||||
* glibc 2.33
|
||||
* binutils 2.34
|
||||
* busybox 1.33.1
|
||||
|
||||
|
||||
|
||||
Along with the above-listed packages, there are many others that have also received upgrades. You can get the full technical details in the [official release announcement][2].
|
||||
|
||||
### Download OpenWrt 21.02
|
||||
|
||||
You can head to its official website to download the latest stable builds or opt for development snapshots for experiments.
|
||||
|
||||
Instructions to build your own packages, and firmware should be available in their documentation.
|
||||
|
||||
The _sysupgrade_ command can be used to upgrade your system from OpenWrt 19.07 to OpenWrt 21.02. Do note that you won’t be able to upgrade from 18.06.

OpenWrt 21.02 发布，支持 Linux 内核 5.4 和 WPA3
|
||||
======
|
||||
|
||||
|
||||
|
||||
OpenWrt 社区宣布了该发行版的最新稳定版本：OpenWrt 21.02。
|
||||
|
||||
补充一句，OpenWrt 是一个帮助你创建嵌入式设备定制操作系统的项目。
|
||||
|
||||
它使用户能够根据他们的网络需求公开定制他们的设备，这是市面上销售的路由器的固件所没有的功能。除了路由器之外，OpenWrt 还可以在各种设备上运行，如智能手机、住宅网关，甚至是 32 位的个人电脑。
|
||||
|
||||
自从旧的 OpenWrt 19.07 以来，这个版本的发布带来了超过 5800 个新提交。
|
||||
|
||||
让我们来看看 OpenWrt 21.02 有哪些新功能。
|
||||
|
||||
### OpenWrt 21.02 有什么新内容？
|
||||
|
||||
虽然有一些技术上的变化和改进，但让我强调一下主要的新增内容。
|
||||
|
||||
#### WPA3 支持
|
||||
|
||||
虽然在 19.07 版本中就已经存在，但这个最新的 Wi-Fi 网络安全标准现在已默认包含在镜像中了。
|
||||
|
||||
WPA3 的意思是<ruby>Wi-Fi 受保护接入第三版<rt>Wi-Fi Protected Access 3</rt></ruby>，与流行的 WPA2 相比，在安全方面有很大的改进，也向后兼容。
|
||||
|
||||
#### TLS 和 HTTPS 支持
|
||||
|
||||
就像 WPA3 一样，它也默认包括了 TLS 和 HTTPS 支持，并且带有来自 Mozilla 的可信 CA 证书。
|
||||
|
||||
有了这个支持，无需其它工作，`wget` 和 ` opkg` 现在可以通过 HTTPS 获取资源了。此外，除了 HTTP 之外，[LuCl][1] 也可以通过 HTTPS 获得。
|
||||
|
||||
#### 初步的 DSA 支持
|
||||
|
||||
正如其发布公告中所说：
|
||||
|
||||
> “DSA（<ruby>分布式交换机架构<rt>Distributed Switch Architecture</rt></ruby>）是关于可配置的以太网交换机的 Linux 标准。”
|
||||
|
||||
这取代了直到现在还在使用的 `swconfig` 系统，是对 VLAN 和交换机端口管理方式的一个明显变化。
|
||||
|
||||
#### 新的最低硬件要求
|
||||
|
||||
随着 OpenWrt 的众多新功能和更新，以及 Linux 内核的大小的普遍增加，其最低硬件要求也被提高。
|
||||
|
||||
现在设备需要至少 8MB 的闪存和 64MB 的内存来运行默认的构建版本，以确保适当的稳定性。
|
||||
|
||||
#### 软件包更新
|
||||
|
||||
该版本还包含了几个软件包的升级，其中一些是：
|
||||
|
||||
* Linux 内核 5.4.143
|
||||
* gcc 8.4.0
|
||||
* glibc 2.33
|
||||
* binutils 2.34
|
||||
* busybox 1.33.1
|
||||
|
||||
除了上述列出的软件包，还有许多其他软件包也得到了升级。你可以在 [官方发布公告][2] 中了解完整的技术细节。
|
||||
|
||||
### 下载 OpenWrt 21.02
|
||||
|
||||
你可以前往其官方网站下载最新的稳定版，或者选择开发快照进行实验。
|
||||
|
||||
构建自己的软件包和固件的说明应该可以在其文档中找到。
|
||||
|
||||
可以使用 `sysupgrade` 命令将你的系统从 OpenWrt 19.07 升级到 OpenWrt 21.02。请注意，你无法从 18.06 升级。
