问题 In kernel version before 5.2, I use save_stack_trace_tsk to retrieve call stack. But this method is no longer available in Linux kernel 5.2+, what should I use? 回答1: This question seemed so tempting so I did some digging here is my findings. TLDR; stack_trace_save () functions replaced by arch_stack_walk() interfaces * this is part of consolidation plan and remove duplicate code. linux commit 214d8ca6ee854 provide common architecture to walking stack trace. the new interface called arch_stack

问题 Whenever I start jupyter notebook and create a new python 3 notebook I get an error message saying kernel has died. I have tried deleting and installing ipython, python3.6.5, and jupyter notebook but I still get the error message.

Virtualbox 6.1.10, Ubuntu 20.04 bad return status build on kernel 5.8.0, package virtualbox-dkms error

由 我的未来我决定 提交于 2021-01-26 17:12:41
问题 Not so much as a question as a documentation. This is regarding a failing apt-get install or update related to virtualbox 6.1.10, Ubuntu 20.04, and virtualbox-dkms package failing to build. I had an issue recently with Ubuntu 20.04 and Virtual Box 6.1.10 that's similar to what has been documented here and here. The issue was that installing virtual box from the ubuntu software center installed v6.1.10 which is incompatible with the current ubuntu kernel version, v 5.8.xx. These are all known

Linux Kernel code in memory check with sha256 sum

由 房东的猫 提交于 2021-01-21 11:45:28
问题 Is there a way of finding the loaded kernel code inside the memory? I mean the bootloader loads the kernel and executes it. The kernel extracts itself and start to initialize the hardware and runs init. As I understand the kernel is saved and loaded from the (b)zImage from disk. This unchanged code I want to find inside the memory of the system and check it. I have the following enhancement: Create a sha256 hash of the loaded kernel code and compare it to a defined value to audit the security

Failed to start the kernel on jupyter notebook

问题 I have python versions 3.6.5_1 and 3.7.0 installed via Homebrew. jupyter needs python 3.6 for launching. It wouldn't start if I switch to python 3.7 . After launching, it fails to start the kernel. Giving this error: Traceback (most recent call last): File "/usr/local/Cellar/jupyter/1.0.0_4/libexec/vendor/lib/python3.6/site-packages/tornado/web.py", line 1543, in _execute result = yield result File "/usr/local/Cellar/jupyter/1.0.0_4/libexec/vendor/lib/python3.6/site-packages/tornado/gen.py",

如何下载android源码与android内核源码

由 时光总嘲笑我的痴心妄想 提交于 2020-12-15 04:39:04
首先，要分清楚， android的源代码和android的内核代码一般是分开的 ，要分别进行下载。 1、先下载android的源代码。（这里不包括android的内核代码） 下载最新的源代码，一般上官网下载。网址： http://source.android.com/source/downloading.html 注意：当遇到 error：Exited due to gc error 的错误时，执行 repo sync -j1； 每当下载停止的时候，可以用 repo sync进行继续下载，而不需重新来过。文件总共6G左右， 2、下载android的内核源码 1、首先要安装git ，git1.7.2以上版本，不然会报错，网上百度一下，容易下载到。可以执行命令 ： sudo apt-get install git 2、建立一个存放android内核源码的mykernel目录，进入该目录，并使用如下命令下载内核源码 ，可以使用如下命令： $ git clone https://android.googlesource.com/kernel/common.git 或者 $ git clone https://android.googlesource.com/kernel/goldfish.git 目前新版本的基本上只要下goldfish.git就可以了
