helloworld: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3,forGNU/Linux 5.16.9, with debug_info, not stripped 了解你的交叉编译器 可以通过查询gcc发现很多东西。例如,要找到版本,你可以使用--版本: $ arm-cortex_a8-linux-gnueab...
Some executable files have an s in the user permissions listing instead of an x. This indicates that the executable is setuid, meaning that when you execute the program, it runs as though the file owner is the user instead of you. Many programs use this setuid bit to run as root in ...
We will change some of these later 为下面的动态加载器执行获取内核空间page 设置栈空间,栈的设置支持加上一个随机偏移地址作为一种安全措施,设置参数的起始地址,参数包括命令行参数和环境变量 */ retval = setup_arg_pages(bprm, randomize_stack_top(STACK_TOP), executable_stack); if (retval < 0) goto ...
but you can only access a file in a directory if the directory is executable. (One common mistake people make when setting the permissions of directories is to accidentally remove the execute permission when using absolute modes.)
%t UNIX time of dump %h hostname %e executable filename# 查看coredump命名规则配置$cat/proc/sys/kernel/core_pattern 有时,在java进程上执行jmap时,会无法执行成功,这时可以使用gcore替代生成coredump,然后使用jmap转换为mat可以分析的hprof文件。

Linux下标准的可执行文件格式是ELF.ELF(Executable and Linking Format)是一种对象文件的格式,用于定义不同类型的对象文件(Object files)中都放了什么东西、以及都以什么样的格式去放这些东西。它自最早在 System V 系统上出现后,被UNIX世界所广泛接受,作为缺省的二进制文件格式来使用。
KERNEL_CONFIG_PATH := $(OHOS_BUILD_HOME)/kernel/linux/config/${KERNEL_VERSION} DEFCONFIG_FILE := $(DEVICE_NAME)_$(BUILD_TYPE)_defconfig 须知: 由于OpenHarmony工程的编译构建流程中会拷贝kernel/linux/linux-*.*的代码环境后进行打补丁动作,在使用OpenHarmony的版本级编译命令前,需要kernel/linux/linux-...
$ sudo apt-get install gdb 6.1 分析 core dump 文件中的堆栈信息 要分析 core dump 文件中的堆栈信息,请使用以下命令: $ gdb /path/to/executable /path/to/core/file 这将打开 GDB 命令行界面并加载 core dump 文件。您可以使用 bt 命令查看堆栈跟踪信息: ...
