Idan Horowitz f972eda7ed Kernel: Mark cloned volatile purgeable AnonymousVMOjects as purged ... Our existing AnonymousVMObject cloning flow contains an optimization wherein purgeable VMObjects which are marked volatile during the clone are created as a new zero-filled VMObject (as if it was purged), which lets us skip the expensive COW process. Unfortunately, one crucial part was missing: Marking the cloned region as purged, (which is the value returned from madvise when unmarking the region as volatile) so the userland logic was left unaware of the effective zero-ing of their memory region, resulting in odd behaviour and crashes in places like our malloc's large allocation support.		2023-12-22 10:57:59 +01:00
