Deadlocks

Deadlocks are situations where processes are unable to continue in their work because each process has locked a resource that a different process also requires. This causes an unending loop of waiting during which processes are unable to be carried out (Mutual Exclusion). To avoid this problem the operating system must have a way to detect deadlocks. It should also be able to identify them when they occur.

To prevent deadlocks, it's common to allocate all resources to one category. For example it is possible to divide the resources available into categories like memory, printers, or CPUs. In this way, all processes will be able to access the same resources without creating deadlocks.

This technique can be combined with a basic Banker’s algorithm to identify deadlocks. This method checks the status of each process and if they haven't completed their task, it's considered that the process is locked. However, this method is not 100% reliable. A programmer can still create a deadlock which the operating system could not recognize.

To avoid deadlocks, you can also demand that each process release its own resources before requesting any new ones. This allows the operating system to anticipate requests for processing and free existing resources. This prevents starvation of resources however it has its drawbacks such as late process inception and frequent preemptions.

Another option is to use a deadlock detection system that makes use of a queue to keep track of the state of each process and its children. This kind of mechanism can be useful in identifying deadlocks that can't be detected with a simple dynamic test. It is only possible to use if the operating systems are designed to support such a fix.

Other methods of preventing deadlocks is to use a priority queue, where each process is assigned a numeric priority. The higher the priority of a process, the more likely it will be the victim of a rollback. This method is good to reduce the number of deadlocks, however it could result in low-priority processes being postponed indefinitely. This is why it is not recommended for high-priority tasks.

Inner pin stacks are the most important to this level. They are arranged as dimpled layers inside the outer driver stacks. Small islands in the center of these dimples control lift of the inner pin stacks, allowing them to reach their shearline. Once they are there they press against the binding inner key-pin to set. The outer drivers can be lifted out of the plug, and the lock is now open.

This system also offers protection against extraction pulling attacks. This is achieved by adding an interior shear line that makes it harder to ram the cylinder using an external tool. It also incorporates a shear point on the top and the bottom of the cylinder for additional protection.
