3 years ago 看样子是 CPU 指令集不支持对应的指令。 给我们一点时间调查。

3 years ago 原因是 XTLS 用的 copy go 1.15.2 的 cpu 换成了 x/sys/cpu（标准做法）
根据 TG 上的反馈，该 CPU 上 termux 直接运行 v2ray-core v4.31.0 没有问题，但 magisk 有问题，所以建议给 magisk 提个 issue

3 years ago I can reproduce this with Magisk-Modules-Repo/v2ray on a Snapdragon 845 Android 10 phone. Replacing v2ray with v4.31.0 arm32 ones works for me. Replacing v2ray with arm64 versions before commit VLESS PREVIEW 2.3 work for me. (Maybe related to XTLS/Go commit import "golang.org/x/sys/cpu")

But I can grab v4.31.0 arm64 binaries from release and make a minimal Magisk module without illegal instruction error.

3 years ago OK, seems chmod 6755 v2ray cause the crash. Commenting this line and chmod 0755 v2ray can temporarily solve it.
To reproduce the crash, v2ray binary should be

3 years ago I grabbed the latest source code and built Android version of v2ray and v2ctl on Termux. It totally works and I cannot reproduce the crash anymore.
Maybe we should not grab Linux builds for Android use?
Those who encounter the same error can try if this build works.
v2ray-android-arm64-v8a.tar.gz
:/data/data/com.termux/files/home # v2ray -version
V2Ray 4.31.0 (V2Fly, a community-driven edition of V2Ray.) Custom (go1.15.2 android/arm64)

magisk test ?
How did you compile？

Yes.
How did you compile？
just follow https://www.v2fly.org/developer/intro/compile.html and run on Termux:
apt install golang git
git clone https://github.com/v2fly/v2ray-core.git
cd v2ray-core
go mod download
CGO_ENABLED=0 go build -o $../v2ray -trimpath -ldflags "-s -w -buildid=" ./main
CGO_ENABLED=0 go build -o $../v2ctl -trimpath -ldflags "-s -w -buildid=" -tags confonly ./infra/control/maincross-compilation GOOS=android GOARCH=arm64 on PC also works.

3 years ago Did you modify the permissions?

3 years ago Of cource I tested it. The go1.15.2 android/arm64 build works even if permission 6755 and magisk-mounted.

3 years ago 似乎不是 v2ray-core 的问题？
推测：
v2ray Magisk模块的作者将v2ray所有者、用户组为设置为inet，权限设置为6755 see this
Android 上/proc/self/auxv权限为0400，所有者、用户组为root
v2ray读取/proc/self/auxv返回错误，转而执行一段汇编代码getisar0()并crash
其他情况下能够正常读取/proc/self/auxv，规避了这个问题
arm linux版本和goos=android 版本则完全没有这部分代码

3 years ago 重新刷magisk 20.3 版本即可解决，20.4有兼容问题。
not Magisk fault and Magisk 20.3 not work for me (tested with v2ray-core 4.31.0)
Anyway this issue should be closed due to the removal of xtls. (XTLS/Xray-core added Android arm64-v8a build for this as well)
