Solve Xposed module list become empty on Android 6.0 Marshmallow

0   9218 转为繁体

Recently I found module list in Xposed become empty after I upgrade my Nexus5 to 6.0.1 (M4B30Z, Dec 2016). And all the modules are not activating. So I open logcat and see the following:

Rovo89 said on a xda post that this file should be created if any module is activated. But somehow it didn’t do so on my Nexus5. So I create one myself and set correct permission (0644) and uid (you can run the Xposed Installer app and check the uid through ps |grep xposed). Then I reboot and check logcat again:

Looks like it’s still not working.

Then I realise that Android started to set SELinux to enforce from Lollipop (5.0) so this should be the problem. (We can use dmesg|grep audit to check if the problem really related to SELinux. ) I compared a random file under /data/data to the file we just created:

So all we need to do is to change this conf/modules.list to u:object_r:app_data_file:s0:c512,c768 as well

restorecon is a applet shipped with toybox, we can also use chcon to manually set SELinux context.

解决Android 6.0 Marshmallow中Xposed的模块列表为空

升级Nexus5 到6.0.1 (M4B30Z, Dec 2016)之后,Xposed的模块列表变成空的了,所有的模块也都失效了。没有xposed,怎么种庄稼。于是我打开logcat看了一眼。

rovo89在xda的QA帖中说一般情况下这个文件会在启用任意一个模块后创建。然而现在它并没有被创建。于是我去建了一个,然后chmod 644以及chown到应用到uid(可以通过启动应用之后ps|grep xposed查看uid,形如u0_a??),重启了一下,再瞄了一眼logcat。

好像哪里不对

想起来Android从萝莉棒开始SELinux就是enforce了,所以大概是这个问题。(我们可以通过dmesg|grep audit来查看被SELinux过滤的各种奇怪操作。)于是看了一下默认的文件context和我们刚创建的文件的context:

那么我们把这个conf/modules.list也改成u:object_r:app_data_file:s0:c512,c768这个context好了

restorecon是toybox中带的一个applet,我们也可以用chcon来手动更改context。

一个使用Cloudflare API v4的动态DNS脚本

0   13922 转为繁体

分享一个使用Cloudflare API v4的动态dns脚本(Gist地址本地下载)。

因为11月Cloudflare就要下线v1版本的API了,而Openwrt里的ddns-scripts并没有支持新版[摊手],所以自己写了一个。

仅依赖curl(可以改成wget)。支持v4和v6。会请求ip.yooooo.us得到公网IP地址,怕隐私泄露的可以自己搭一个

 

This is a DDNS script using Cloudflare APIv4 written in bash (Gist or Download directly).

I wrote this because Cloudflare is going to remove support for the old API on Nov. this year. And the ddns-scripts package in Openwrt is not yet supporting the new API [摊手].

This script only depends on curl (can be modified to use wget). It will use ip.yooooo.us to query IPv4 and IPv6. You can use this link to set up your own query server.

deluge各种问题导致状态机抽风

6   10446 转为繁体

遇到一个问题,设置了deluge分享率和做种时间到一定时间之后自动删除种子。之前一直很好使的,最近发现到了指定的分享率或者做种时间之后,种子状态变成了一直Paused或者一直Seeding。发现有这么几种问题导致deluge抽风:

状态存档的权限不对

是deluged没有对状态存档~/.config/deluge/session.state和~/.config/deluge/state/*的写权限导致的。

因为自身需求使用

#  start-stop-daemon -S -c user:www-data -k 000 -x /usr/bin/deluged — -d

启动deluged,deluged具有user的euid和www-data的egid,而~是user:user的。所以就挂了233

直接添加种子下载地址导致一直Paused

deluge可以直接添加种子的http下载地址,取得种子之后自动开始下载,但是这样有一定几率产生万年Paused。

解决办法是自己下载种子之后返回磁力链添加到deluge。
