What are the general tendencies related to the Linux Kernel?

[Sammiel]

Actually I want to know the general tendencies related to the Linux Kernel. Nobody can deny the fact that the development task related to the Linux Kernel are very complex and can be said as strange. Since it is maintained by the number of different parts and what there is countless number of persons which can submit the code making it to difficult which is the latest trend in it.

Linux in real-time operation received considerable improvements since it is now often used as mobile phones and other devices embedded systems. But the recently released 2.6.23 kernel show that it in real-time operation, "a little step backward," commercial embedded Linux vendor MontaVista's Chief Technology Officer (CTO) and co-founder Jim • Rui Erdi (Jim Ready) complained. This new process scheduler a more emphasis on "fairness" - which means by the end user to tell which processor the task to be processed, can get a higher priority.

According to me "Real-time users do not need fair," Rui Erdi that, because real-time requirements, whether CPU is doing, can insert a new priority to interrupt the operation. A simple example is that of patients in the medical devices, monitoring software, the discovery of the patient breathing, they can send an immediate warning, the software no matter what the task in dealing with it must first break stop.

The reason is because the kernel developers are committed to making the process scheduler with real-time capabilities. The key part of the operating system is interrupt management - which determines what tasks can get CPU processing power, how they are arranged between the different behavior priority. If all interrupt processors can be integrated into their own thread and going, that thread can be scheduled and set priorities, rather than run and delay cannot predict the real-time response.

Everyone wish to have a more secure system. Novell the release of SUSE Linux Enterprise Server 10 at the same time with the release of the Apparmor, it is a limited application can access what resources the operating system software, which can restrict the use of illegal unauthorized access, caused harm. However, it is unlikely in the near future will be added to the kernel.

Linux Security the authority of the experts, another set of security mechanisms SELinux developer Stephen • Si Malai (Stephen Smalley) think that AppArmor cannot be added to the kernel because of its protective mechanism is based on the "path name" approach, it is essentially is a white list settings, Apparmor only allows applications to access files on the list, all other documents cannot be accessed. According to last year • Corbett Jonathan (Jonathan Corbet) report, the Si Malai that a clever intruder can take advantage of the path name of a legitimate guess the name of the other, creating unnecessary exposure.
