Error when using --stack option in Redroid

isjuye commented 3 months ago

您好，

在 Redroid 中对所有应用程序和选项添加 --stack 选项时，出现以下错误，导致无法输出 stack：

Error when GetStack:[GetStack] get pid_maps failed by pid:2017599488

当前在 Redroid 上运行：

redroid_arm64:/data/local/tmp # uname -a
Linux localhost 6.5.0-1025-oracle #25~22.04.1-Ubuntu SMP Fri Jun 14 14:45:36 UTC 2024 aarch64

特别情况：

130|redroid_arm64:/data/local/tmp # ./stackplz
CheckKernelConfig failed, error:Kernel config read failed, error:open /proc/config.gz: no such file or directory
1|redroid_arm64:/data/local/tmp #

由于 Ubuntu 中不存在 /proc/config.gz 文件，因此必须使用 --nocheck 选项。

以下是执行命令和完整日志：

执行命令：

./stackplz --nocheck -n re.pwnme -s openat:f0 --no-tname crash_dump64 -f w:/sbin/su --stack

请帮忙确认此问题并提供解决方案。谢谢。

btf不匹配问题，你需要在host开启BTF，然后使用--btf 选项
