Basics
Rights are associated with handles and convey privileges to perform actions on either the associated handle or the object associated with the handle.
The <zircon/rights.h> header defines
default rights for each object type, which can be reduced via
zx_handle_replace() or zx_handle_duplicate().
| Right | Conferred Privileges |
|---|---|
| ZX_RIGHT_DUPLICATE | Allows handle duplication via zx_handle_duplicate() |
| ZX_RIGHT_TRANSFER | Allows handle transfer via zx_channel_write() |
| ZX_RIGHT_READ | Allows reading of data from containers (channels, sockets, VM objects, etc.) |
| Allows mapping as readable if ZX_RIGHT_MAP is also present | |
| TO BE REMOVED Allows inspection of object state | |
| ZX_RIGHT_WRITE | Allows writing of data to containers (channels, sockets, VM objects, etc.) |
| Allows mapping as writeable if ZX_RIGHT_MAP is also present | |
| TO BE REMOVED Allows modification of object state | |
| ZX_RIGHT_EXECUTE | Allows mapping as executable if ZX_RIGHT_MAP is also present |
| ZX_RIGHT_MAP | Allows mapping of a VM object into an address space. |
| ZX_RIGHT_GET_PROPERTY | Allows property inspection via zx_object_get_property() |
| ZX_RIGHT_SET_PROPERTY | Allows property modification via zx_object_set_property() |
| ZX_RIGHT_ENUMERATE | Allows enumerating child objects via zx_object_get_info() and zx_object_get_child() |
| ZX_RIGHT_DESTROY | Allows termination of task objects via zx_task_kill() |
| ZX_RIGHT_SET_POLICY | Allows policy modification via zx_job_set_policy() |
| ZX_RIGHT_GET_POLICY | Allows policy inspection |
| ZX_RIGHT_SIGNAL | Allows use of zx_object_signal() |
| ZX_RIGHT_SIGNAL_PEER | Allows use of zx_object_signal_peer() |
| ZX_RIGHT_WAIT | Allows use of zx_object_wait_one(), zx_object_wait_many(), and other waiting primitives |
| ZX_RIGHT_INSPECT | Allows inspection via zx_object_get_info() |
| ZX_RIGHT_MANAGE_JOB | NOT YET IMPLEMENTED Allows creation of processes, subjobs, etc. |
| ZX_RIGHT_MANAGE_PROCESS | NOT YET IMPLEMENTED Allows creation of threads, etc. |
| ZX_RIGHT_MANAGE_THREAD | NOT YET IMPLEMENTED Allows suspending/resuming threads, etc. |
| ZX_RIGHT_APPLY_PROFILE | Allows a scheduling profile to be applied to a thread via zx_object_set_profile() |
| ZX_RIGHT_MANAGE_SOCKET | Allows changing socket disposition via zx_socket_set_disposition() |
| ZX_RIGHT_OP_CHILDREN | Allows for operations on a parent object to also modify children |
| ZX_RIGHT_RESIZE | Allows resizing a VM object if ZX_RIGHT_WRITE is also present |
| ZX_RIGHT_ATTACH_VMO | Allows attaching and detaching VM objects to a pager |
| ZX_RIGHT_MANAGE_VMO | Allows managing the contents and metadata of a pager-owned VM object |
ZX_RIGHTS_BASIC
The basic rights allow primitive manipulation of handles and are common to the majority of handle types by default. These are ZX_RIGHT_DUPLICATE, ZX_RIGHT_TRANSFER, ZX_RIGHT_WAIT, and ZX_RIGHT_INSPECT.
These four rights are referred to as ZX_RIGHTS_BASIC when used together.
