Modules§

get_kernel_vm_manager
get_trampoline_arch
get_trampoline_trap_vector
kernel_vm_init
kstack_alloc 🔒
set_trampoline_arch
set_trampoline_trap_vector
setup_trampoline_for_task_kstack_window: Map the task’s kernel stack physical pages into the shared kernel PT at a unique high VA window. Adds an unmapped guard page at the bottom of the window.
setup_user_stack
switch_to_kernel_vm
switch_to_user_vm
teardown_trampoline_for_task_kstack_window: Unmap and free the task’s kernel stack window from the shared kernel PT.
user_kernel_vm_init
user_vm_init
verify_task_kernel_stack_guard: Verify that a task’s kernel stack guard page is unmapped and stack pages are mapped. Returns true if the guard page has no associated memory map and a sample stack address is mapped.
