The kernel must store the state (context) of each running process in order to switch between them. This involves storing memory contents specific to each process. - Process management: The kernel maintains tables and data structures that describe the state of each process in the system, including...

If the BIOS version of 1.0 series is 1.83 or later or that of 3.0 series is 3.37 or later, and kernel address randomization is enabled for the faulty node, go to 34.c.ii. Otherwise, go to 35. Perform the following operations to disable the memory randomization function: Open the grub...
The libseccomp library provides an easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism. The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that...
