Method Details

find_vnode_object(self)

source code

Find the underlying vnode object for the given vm_map_entry.

xnu-2422.1.72/osfmk/vm/bsd_vm.c: 1339.

Property Details

sharing_mode

Returns the sharing mode of the backing vm_object.

This is losely adapted from vm_map.c, void vm_map_region_top_walk(), except we're not filling page counts for resident/reusable, etc.

Get Method:: unreachable.sharing_mode(self) - Returns the sharing mode of the backing vm_object.

code_signed

Get Method:: unreachable.code_signed(self)

last_shadow

Get Method:: unreachable.last_shadow(self)

start

Get Method:: unreachable.start(self)

end

Get Method:: unreachable.end(self)

vmo_object

Return the vm_object instance for this entry.

There's an intermediate link called struct vm_map_entry.

The members will be called either 'object' and 'vm_object' or 'vme_object' and 'vmo_object'.

There is no easy heuristic for which it will be in a particular kernel version* so we just try both, since they mean the same thing.

* The kernel version numbers could be identical for kernels built from a feature branch and a kernel build from trunk, and the two could be months apart. Furthermore, the profiles are generated not from the kernel itself but from a debug kit and can end up using out of date naming conventions.

Get Method:: unreachable.vmo_object(self) - Return the vm_object instance for this entry.
