After a system has experienced an oops, some internal resources may no longer be operational. Thus, even if the system appears to work correctly, undesirable side effects may have resulted from the active task being killed. A kernel oops often leads to a kernel panic when the system attempts to use resources that have been lost. Some kernels ...
The report suggests that the Linux kernel may have been created or distributed illegally and that open-source software may be generally subject to such abuses. The report states that the Linux kernel was written using copied source code from Minix and other resources acquired improperly or possibly illegally by Linus Torvalds.
During the final stages of kernel userspace initialization, a panic is typically triggered if the spawning of init fails. A panic might also be triggered if the init process terminates, as the system would then be unusable. [11] The following is an implementation of the Linux kernel final initialization in kernel_init(): [12]
Boot messages of a Linux kernel 2.6.25.17. The basic components of the Linux family of operating systems, which are based on the Linux kernel, the GNU C Library, BusyBox or forks thereof like μClinux and uClibc, have been programmed with a certain level of abstraction in mind.
kpatch is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kpatch aims to maximize the system uptime and availability.
The Linux kernel is a free and open source, [11]: 4 Unix-like kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free replacement for Unix.
Location of the "O(n) scheduler" (a process scheduler) in a simplified structure of the Linux kernel. The O(n) scheduler [1] is the scheduler used in the Linux kernel between versions 2.4 and 2.6. Since version 2.6.0, it has been replaced by the O(1) scheduler and in 2.6.23 by the current Completely Fair Scheduler (CFS).
Greg Kroah-Hartman is a major Linux kernel developer. As of April 2013, he is the Linux kernel maintainer for the -stable branch, [2] the staging subsystem, [2] USB, [2] driver core, debugfs, kref, kobject, and the sysfs kernel subsystems, [2] Userspace I/O (with Hans J. Koch), [2] and TTY layer. [2]
