The purpose of this ticket is to systematically hunt down the majority of bugs in the networking stack. Details:: There are several open tickets related to the HelenOS networking stack ([ticket:546 #546], [ticket:589 #589], [ticket:627 #627], [ticket:628 #628]) and generally speaking the networking stack is still not behaving flawlessly. People usually avoid stressing the networking stack or putting it under high demand. The practical 100% reliability that one expects from a networking stack is simply just not there yet. The purpose of this ticket is to systematically hunt down the majority of bugs in the networking stack (i.e. all major bugs that can be detected, reproduced, triaged and fixed in the given time frame). This requires designing and implementing a rigorous and robust methodology that would be able to objectively determine whether the degree of reliability of the networking stack actually improves over time. This methodology should be based on a set of stress tests for all major aspects of the networking stack operation, with mostly automatic evaluation of the stress tests. The purpose of this ticket is not to improve the overall performance of the networking stack, although trivial performance bottlenecks and performance issues that break conformance (incorrect timeouts, etc.) are still covered by this ticket. What Gains and Benefits will this bring?:: When the work on this ticket is over, the HelenOS networking stack should no longer be considered a working prototype, but instead a production-ready implementation. Other components can readily rely on the reliability of the networking stack. Difficulty:: High Required skills:: A successful applicant will have good skills of programming in the C language, the ability to understand a non-trivial amount of existing C code and good analytical skills (both for designing the assessment methodology and for finding root causes of bugs).
