linux kernel security

1. Create a kernel for the embedded platform (the 6410 Development Board is used as an example here) 1. Clear the original configuration and intermediate files (1) x86: Make distclean (2) arm: Make distclean 2. Configure the kernel (1) x86: Make menuconfig (2) arm: Make menuconfig arch = arm (platform to be specified) 3. Compile the kernel (1) x86: Make bzimage (

Programs running in the Linux kernel should always prevent competing states caused by concurrency. This will cause the data structure to be broken down and cause the kernel to crash in severe cases. Therefore, the kernel synchronization technology is very important to the driver developed by the

The Linux kernel of Android is stored in the kernel subdirectory. By comparing it with the standard Linux 2.6.25 kernel, we can find that it mainly adds the following content: 1. Add the gold-fish platform based on the ARM architecture. The directories added are as follows:

One, the Linux kernel compared to the traditional Unix kernel comparison:(1): Linux supports dynamic kernel modules. Although the Linux kernel is also a monolithic structure, it allows

I. Linux configuration and compilation Linux has the following advantages: 1. Clear temporary files, intermediate files, and configuration files (1) make clean: delete most of the generated files, but keep the configuration file (2) Make mrproper: delete all generated files and configuration files (3) make distclean: Delete the patch and backup files of the editor based on make mrproper. 2. Deter

corresponding __attribute__ parameters in parentheses.The syntax format is: __attribute__ ((attribute-list))Attribute sections are used for functions and variables, and typically the compiler places functions in the. Text section, where variables are placed in the. data or. BSS sections, and the section property allows the compiler to place functions or variables in the specified section.2, meaning of Is_err () in driverAll drivers are running in kernel
