Hello, I am interested in wrinting code in Linux kernel and I started write kernel modules. I have some basics about kernel development- I red Robert's Love book. My the biggest project with kernel code is simple module, which create char device which can execute commands as root. Actually I'm reading Linux device drivers 3rd edition. And I haven't any idea what I could doing. I have many ebooks about kernel, but I prefer learn by writing some code. Sorry for my banal question (propably you haven't many time), but when someone answer me, I will be very very thankful.
I would suggest you to: 1) Complete eudyptula challenge. It contains 20 kernel-related tasks. I have completed 8th task and awaiting to response and I want to say that this is a very good challenge for newbies. 2) Pick one of the areas in which you want to participate in. It might be virtualization, networking, storage, drivers, etc.. Any of that. Go to the appropriate kernel bug tracker, pick a bug and then try to reproduce it, fix it and send it as a patch. I tried many different strategies in last 8 months, but it seems that this one is the most obvious and efficient. After you complete it you will know enough to continue without any advices )
