Hi,
At the LSF/MM summit, I would like to discuss the following topics:
- Dynamic allocation of protectable (read/only) memory in kernel space
- Rare Write option for the aforementioned dynamic allocation
(this is most likely related to Kees Cook's rare-write proposal)
- Support for userspace to mprotect selected pages:
* as permanently R/O
* as rare write
(this might be easier to implement than kernel rare-write)
Probably both of these will also require a separate userspace memory
allocator, which understands pools, or at the very least, can support
different types of pages.
- Optimization of vmalloc (combining vmap_area and vm_struct structures)
