Hi all, I'm developing a LKM. I'm working on threads that, as obvious, share the same process address space. I' ve already setted the shared portion of memory as not writable. Now I've to manage the access to this memory by having a notification any time a thread tries to write on. I think the solution is to change an exception handler but I've not an idea of what exception handler is called when a process tries to write on a "not writable" portion of memory... AFAIK it is the page fault handler which is called while traversing the page table. Can anyone help me or give me other suggests? Thanks. Vincenzo. ___________________________________ Nuovo Yahoo!
