I suggest that useful partial progress can be made sooner by
identifying the allocators, telling valgrind about them and their
external semantics, and having valgrind trust them.
This is likely what will happen anyway. It will likely generate noise from inside the allocators until they are described. It probably won't be the allocators which generate warnings. The main problem will be that newly allocated memory will still be considered initialized by its previous owner. Also, if UML allocates memory using mmap, all memory will be considered to be initialized. Waiting for the globally correct description can take a long time,
perhaps about as long as waiting for the authors of device drivers to
update to a new device I/O model.
Nonsense. They aren't going to be that complicated, and they don't change very often anyway. Doing a few base-level allocators first (get_free_page, kmalloc) will find lots of problems, then you can start refining to the more specialized allocators. J | ||||||||||
