Description of the problem

I'm trying to interface DCE with the Linux Kernel Library. I am a bit unsure about how the current Process/Thread/Task system is working. I do have a basic understanding. However, I am facing a problem while trying to interface with LKL.

During the call to InitializeStack

ns-3-dce/model/kernel-socket-fd-factory.cc

Line 558 in aa5de62

KernelSocketFdFactory::InitializeStack (void)

The call to Current:

ns-3-dce/model/utils.cc

Line 121 in aa5de62

Thread * Current (void)

which is supposed to be the current thread, is returning null. This does not cause any problems with net-next-nuse, but I need to initialize Semaphores etc, inside LKL during its initialization, which in turn needs a context. I am going through the events and figure out why the context is empty, but a general idea about the overall TaskManager class would really help me.

I hope this is the right forum to ask this question.

Thanks,
Usama
