Most of those mistakes cannot be fixed because doing so would break the ABI that the kernel presents to the user space.[7] System Call Interface of the Linux kernel[edit] System Call This has created an incentive towards automatic synthesis and verification of device drivers. The Linux API, by choice, has been kept stable over the decades and never breaks; this stability guarantees the portability of source code.[4] At the same time, Linux kernel developers have The motivation for the project was that 500,000 crashes reported a day were found to be caused by one video driver, leading to concern about the great vulnerability in using complex Source

A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a It was, however, the impetus that Torvalds needed to lead a major restructure of the kernel code to facilitate porting to competing computing architectures.

For example, runtime fault isolation has performance overhead, whereas the static analysis does not cover all classes of errors.

Among the changes that have been made in the 2.6 series are: integration of µClinux into the mainline kernel sources, PAE support, support for several new lines of CPUs, integration of

Most of the included software is free and open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Thus a file system may "know" an area on a disk as /dev/sda3, for example, or "see" a networked terminal session as associated with /dev/pts/14. linux-hotplug (Mailing list).
